All major components are manufac t ured by Eaton, establishing one source of responsibility for the equipment’s performance and ensuring high standards in quality, coordination, reliability and service.A complete line of Eaton switches and fuses is available:■■38 kV voltage class■■600 A continuous loadinterrupting ratings■■Non-fused or fused with current limiting or boric acid-type fuses■■Manual or motor operated■■Indoor or outdoor non-walk-in enclosures■■Single switches and transformer primary switches■■Duplex loadbreak switch arrange m ents for selection of alternate feeds■■Lineups with main bus■■Standard arrangements with auto m atic transfer control systems (two sources feeding one bus or two sources feeding two buses on a split bus with tie switch) Standard design configurations for:■■NEMA T pads for cable lugs■■Surge arresters■■Instrument transformers■■Control power transformers■■Power Xpert T and IQelectronic metering■■Other auxiliary equipmentOutdoor Duplex with Customer MeteringApplication DescriptionEaton’s Load Interrupter T ype MVSmetal-enclosed switchgear provides safe,reliable switching and fault protectionfor medium-voltage circuits rated to38 kV. T he MVS switch is ideal forapplications where high duty cycleoperation is not required.MVS switchgear has the advantage oflow initial cost inherent in switch designswhile offering the characteristics mostvital to safety and coordination.The MVS switch’s quick-make, quick-break mechanism provides full-loadcurrent interrupting capability whilefuses provide accurate, permanentlycalibrated short circuit detecting andinterrupting capabilities. Visibility ofactual blade position improves safetyby giving positive assurance of circuitde-energization.Standards and CertificationsEaton’s MVS load interrupter switchgearmeets or exceeds the requirements ofthe following industry standards:■■IEEE T Standard C37.20.3■■ANSI C37.57■■NEMA SG5■■Canadian Standard CAN/CSA RC22.2 No. 31Type MVS switches meet or exceedthe requirements of the followingindustry standards:■■IEEE Standard C37.20.4■■ANSI C37.58■■ANSI C37.22■■NEMA SG6■■Canadian Standards CAN/CSA C22.2No. 193 and CAN/CSA C22.2 No. 58Load interrupter switches should notbe used to interrupt load currents abovetheir interrupting rating of 600 A, asthey are not designed nor tested forinterrupting fault currents on electricalsystems . Optional fuses can be providedfor phase overcurrent protection .3838150150600–1200600–12004050.46581.92531.5Switch MechanismThe quick-make, quick-break mecha n ism uses a heavy-duty coil spring that provides powerful opening and closing action. T o close the switch, the handle is inserted into the spring charging cam, then rotated upward through an angle of 120 degrees. This action charges the operating spring, as the mechanism is forced past toggle. The stored energy of the spring is released and transferred to the main shaft that snaps the switch closed.As a result of the over-toggle action, the blades are moved independently of the operator. It is impossible to operate the switch into an intermediate position.To open the switch, the handle is inserted into the spring charging cam and rotated downward through 120 degrees resulting in charging of the operating spring,then releasing its stored energy in similar sequence.Quick-Break DE-ION Arc InterruptionWith the switch closed, both main andauxiliary (flicker) blades are closed, andall of the current flows through the mainblades. T he flicker blades are in the closedposition in the arc chutes, but are past thearcing contacts and thus carry no current.As the main blades open, current istransferred momentarily to the flickerblades, which are held in the arc chutesby high pressure contact fingers. T hereis no arcing at the main blades.When the main blades reach a pre-determined angle of opening, a stoppost on the main blades prevents furtherangular movement between the mainand flicker blades. T his starts the flickerblades out of the high pressure contactsin the arc chutes and as contacts arebroken, the flicker blades are snappedinto position by their torsion springs.The heat of the arc, meanwhile, releasesa blast of de-ionizing gas from thegas-generating material of the arc chute.This combination of quick-break andDE-ION action quickly extinguishes thearc and the circuit is safely de-energized.A non-fused switch has the ability to closeand latch four times when rated 40 kA,and one time when rated 61 kA, andcontinue to carry rated current thusadding a large margin of integrity tothe electrical system.Bus Insulation SystemAll bus runs are supported using a highstrength and high creep, finned supportproviding in excess of 24.00 inches(609.6 mm) for 38 kV, of creep distancebetween phases and ground. T he moldedhigh track-resistant fins are constructedas standard of Aramid nylon or optionalCycloaliphatic epoxy.■■Significantly superior bus bracingthan standoff type A20 insulators■■Significantly increased creep distancephase-to-phase and phase-to-ground■■Improved endurance fromfault incidents■■Minimizes bus system failures dueto tracking■■Eliminates additional groundplanes in the switchgear for bussupporting systemsBus SupportFigure 8.3-1. Switch OperationBoth Blades Disengaged Main, Flicker BladesEngagedMain Blades Disengaged,Flicker Blade EngagedDuplex Switch ConfigurationTwo MVS load interrupter switch sections can be used to provide cost- effective source selectivity with a common load side bus feeding one load (fused or nonfused). Key interlocks are a standard feature provided to per m it only one switch to be closed at a time and prevent opening any switch door unless both switches are open.Figure 8.3-2. Typical Duplex Switch Configuration with One K1 Key— Dimensions in Inches (mm)Loadbreak Switch with Grounding Jaw The loadbreak switch can be supplied with optional grounding jaws for auto-matic grounding of the load circuit. When the switch is opened, the switch main blades engage grounding jaws to ground the load circuit. This feature cannot be used in a duplex switch configuration . The ground jaw option is available at38 kV. It is meant for applying a static ground, and is not rated for carrying fault currents.Figure 8.3-3.

Duringthe closing operation, full clearancebetween blades and stationarycontacts is maintained until theswitch mechanism goes over toggle.The switch mechanism has onlymetal-to-metal linkage—no chainsor cables are used.Arc interruption takes place betweencopper-tungsten tipped auxiliary(flicker) blade and arcing contacts witha DE-ION T arc chute; no arcing takesplace between the main blades and the stationary contacts to prolong the lifeof the main blades.Blow-out forces cannot be transmit t ed to the operating handle.b■Provisions for Padlocking DoorHandle not visible in the photo.c■Inspection W indowA large 8.00-inch x 16.00-inch(203.2 x 406.4 mm) gasketed,rectangular, high impact viewingwindow permits full view of theposi t ion of all three switch bladesthrough the closed door.d■Full Height Main DoorThe door has a return flange and tworotary latch-type handles to providelatching members held in shear.

T ests were performed to substantiate all published ratings in accordance with ANSI, IEEE, CSA and NEMA standards.The testing program included tests of:■■Basic impulse levels■■Momentary withstand■■Short-time withstand■■Fault closing■■Load interrupting at various loads, various power factors■■Mechanical life tests■■Temperature rise testThese tests verified not only the per-formance of the switch and integrated switch-fuse assembly, but also the suitability of the enclosure venting, rigidity and bus spacing.The mechanical life test subjected the MVS switch to a number of no load cycles greater than the requirements tabulated in ANSI C37.22 standards. T here were no moving or current carrying part failures as a result.The Fault Close and Load Interrupting test demonstrated significant improved performance above ANSI/IEEE standards. See T able 8 .3-3 and T able 8 .3-4 for results.38381501506006004050.46581.92531.5386005538384050.46581.91111a When RBA expulsion fuses are used, and two ratings appear, the lower rating applies when thelower-rated switch (15 kV, 40 kA fault close, 25 kA short-time current) versus the higher rating that applies when the higher-rated switch (15 kV, 61 kA fault close, 38 kA short-time) is used.Motor Operated MVSApplicationEaton’s MVS Pow-R-Drive E motor operator makes possible the safety and convenience inherent in remote switch operation.Motor Operated MVS Switch DescriptionA MVS Pow-R-Drive motor operatedswitch is a standard, manually operatedswitch in combination with a heavy-dutyelectric motor-driven linear actuator thatcharges the spring. T he linear actuator islocated in a separate isolated low-voltagecompartment. During electrical operation,it smoothly and quietly extends orretracts the proper distance to cause theswitch mechanism to operate.Standard motor operators are mounted inthe switch enclosure. T his eliminates theneed for a separate motor compartmentconserving floor space.Manual Operation OverrideManual OperationTo operate manually, loosen the holdingscrew that keeps the pin connecting thelinear actuator to the mechanism, andremove the pin. Remove the clevis pinon the support of the bottom of the linearactuator. Unplug the cord from thedisconnect i ng terminal block as theactuator is removed and set the actuatoraside. T he switch can now be operatedmanually with the removable handle.Lock Open Key InterlockA keyed lock is standard to lock the switchin the open position only.This lock not only locks the switch in theopen position, but also breaks theelectrical motor contacts integral to themotor control circuit and permits the keyto be removed. With the key, the operatorcan then open the lock on the switch door.This scheme gives positive assurance thatthe switch is open and cannot be closedwith the door open.MeteringElectronic Metering and Communications ApparatusMVS switchgear assemblies can be equipped with Eaton’s family of Power Xpert T and IQ digital meters to monitor a power circuit’s electrical quantities within the capabilities of each device. Eaton’s power management products provide hardware and softwaresolu t ions that allow customers to interface with their switchgear at varying levels of sophistication. Power Xpert and IQ Meters monitor common electrical parameters and communicate the data via standard industry protocols and optional web interfaces. Power Xpert Gateways consolidate devices into a single web browser interface and provide Ethernet connectivity. Eaton’s Foreseer web-based software system can display, analyze and store data from multiple devices across the facility to enable management of the customer’s power system.Electronic Metering Outdoor Enclosures Weatherproofing complying with the requirements of IEEE standard C37.20.3 is available for MVS switch g ear assemblies. The weatherproofing consists of sloped roof panels that are joined together with caps. Doors and rear covers are fully gasketed. Externally accessible louvered filtered covers, top and bottom, front and rear, are provided for ventilation. At least one 250 watt heater is provided in each vertical section. Power for the heaters may be supplied from an external source, or an optional integral control power transformer may be specified to provide power for the heaters.Outdoor EnclosurePower Xpert MeterPXM 4000/6000/8000IQ 130/140/150/250/260Automatic Transfer ControlT wo-Switch Automatic T ransferApplicationEaton’s MVS switchgear with an automatic transfer control system is an integrated assembly of motor operated MVS switches, sensing devices and control components. Available in 38 kV class.It is typically applied where the continuity of service for critical loads from two power sources in either a main/main or a main/ tie/main configuration is desired.MVS switchgear with an automatic transfer control system can meet most automatic throwover requirements as it has a wide variety of operational sequences embodied in one standard automatic transfer control system. Please note that the duty cycle of load interrupter switches is limited by ANSI Standard C37 .22 . Refer to T able 8 .3-3for maximum number of switching operations allowed . If the number of switching operations is expected to exceed the maximum allowed, then load interrupter switches should not be used . Use circuit breakers (refer to T ype MSB, MEB, MEF or V CP-W switchgear designs) . Also note that the operating times of Eaton’s motor operated load interrupter switches are much longer compared to circuit breakers, therefore, the switches are not suitable for closed-transition transfer applications . Use circuit breakers if closed-transition transfer is required . T ypical T wo-Switch AutomaticT ransfer Using ATC ControllerEaton’s ATC-900 controller continu o uslymonitors all three phases on both sourcesfor correct voltages. Should the voltageof the normal source be lost while thevoltage of the alternate source remainsnormal, the voltage sensing function inthe ATC controller will change statestarting the time delay function. If thevoltage of the normal source is notrestored by the end of the time delayinterval, the normal switch will open andthe alternate source switch will close,restoring power to the load.ATC ControllerEaton’s ATC controller is equipped todisplay history information via the frontpanel. ATC-900 controller stores 320 timestamped events. Oscillographic data forlast 10 events can be downloaded via theUSB port or displayed in the controller’sdisplay window. T he controller allowscommunications via RS-232 or Modbusthrough RS-485 port, Ethernet or viaUSB interface.ATC ControllerStandard Features■■Voltage sensing on both sources isprovided by the ATC controller■■Lights to indicate status of switches,sources, etc.■■Interlocking to prevent paralleling ofsources via software■■Control power for the automatictransfer control system is derived fromthe sensing voltage transformers■■Manual override operation■■Open transition on return to normal■■Programmable time delays on bothsources, “OFF DELA Y” and “ON DELA Y”■■Four programmable digital inputsand outputs■■Single-source responsibility; all basiccomponents are manufac t ured by Eaton■■Key interlocking of operating systemand doors where required to provideoperator safetyOptional Features■■Lockout on phase and/or groundovercurrents and/or internal bus faults■■Blown fuse overcurrent lockout■■Load current, power and PF meteringwith optional dcT module■■24 Vdc control power input■■Up to four additional I/O modules, eachwith four programmable digital inputsand digital outputsSurge ProtectionIEEE standard C62.11 for Metal Oxide Surge Arresters lists the maximum rated ambient temperature as 40 °C. T he ambient temperature inside an Eaton MVS switchgear vertical section may exceed this temperature, especially in outdoor applications where solar radiation may produce a significant contribution to the temperature. T able 8 .3-6 lists the recommended minimum duty cycle voltage rating for various system grounding methods. Surge arrester rating is based upon the ambient air temperature in the switchgear vertical section not exceeding 55 °C.33.0034.50 38.0027303022.0024.4024.403030—24.4024.40———————27303022.0024.4024.4036363629.0029.0029.004548—36.5039.00—Note: MCOV = Maximum Continuous Operating Voltage.System OptionsPartial Discharge Sensing and Monitoring for SwitchgearPartial Discharge in SwitchgearPartial discharge (PD) is a common name for various forms of electrical discharges such as corona, surface tracking, and discharges internal to the insulation. It partially bridges the insulation between the conductors. T hese high frequency discharges are essentially small arcs occurring in or on the surface of the insulation system when voltage stress exceeds a critical value. With time, airborne particles, contaminants and humidity lead to conditions that result in partial discharges. Partial discharges start at a low level and increase as the insulation becomes deteriorated. Examples of partial discharge inswitchgear are surface tracking across bus insulation, or discharges in the air gap between the bus and a support (such as where a bus passes through an insulating window between the sections of the switchgear). If partial discharge activity is not detected and corrected, it can develop into a full-scale insulation failure followed by an electrical fault. Most switchgear flashover and bus failures are a result of insulation degradation caused by various forms of partial discharges.Sensing and MonitoringEaton’s T ype MVS metal-enclosedswitchgear (2.4–27 kV) is corona-free by design. By making switchgear assemblies corona-free, Eaton has made its standard switchgear more reliable. However, as indicated above, with time, airborne particles, contaminants and humidity lead to conditions that cause partial discharges to develop in switchgear operating at voltages 4000 V and above. Type MVS switchgear can be equipped with factory-installed partial discharge sensors and a partial discharge sensing relay for continuous monitoring under normal operation. T imely detection ofinsulation degradation through increasing partial discharges can identify potential problems so corrective action can be planned and implemented long before permanent deterioration develops. Partial discharge detection can be the foundation of an effective predictive maintenance program. T rending of partial discharge data over time allows prediction of failures, which can be corrected before catastrophic failure occurs.The PD sensing and monitoring system consists of Eaton’s InsulGard T relay and PD sensors, specifically developed for application in the switchgear to work with the relay. T here are two types of PD sensors used in the switch g ear: the first sensor is a coupling capacitor type sensor developed for use with 5 kV, 15 kV and 27 kV switchgear.The coupling capacitor sensor detects partial discharges within the switchgear cubicle and/or adjacent cubicles, and is typically installed on the load side of the feeder switches or on the main bus. T he second sensor is a small donut type radio frequency current transformer (RFCT). It is designed for installation around the ground shields of incoming or outgoing power cables. It detects partial dis c harges in power cables and monitors for external electrical noise.Typically one set of coupling capacitor sensors is used at every two cubicles. One RFCT sensor is used for each incoming and outgoing power cable circuit.Output signals from sensors (coupling capacitor and RFCT) are wired out to terminal blocks for future or field use, or connected to the InsulGard relay. One InsulGard relay can monitor up to 15 input signals, as well as temperature and humidity. T he temperature andhumidity sensors are included with each InsulGard relay system. T he relaycontinuously monitors the switchgear primary system for partial discharges and provides an alarm signal (contact closure) when high PD level is detected. Also, data analysis and diagnostics by Eaton engineers can also be provided by remote communication with the InsulGard relay.The sensors and InsulGard relay are optional in MVS switchgear .Figure 8.3-5.

Layouts shown are for rear-accessible equipment . Front-accessible designs are available—refer to Eaton . Many other configurations and combinations are available. T wo voltage transformers for metering and one control transformer for auxiliary power can be mounted in the structures shown. For control power above 1 kVA, additional space is required. Depth of units will vary due to cable entrance and exit requirements, the addition of lightning arresters, instrument transformers, special cable terminators, etc. Cables are shown out top and bottom for layout only. T op or bottom must be selected for incoming and for outgoing cables. Cable sizing is based on two 500 kcmil XLP or EPR insulated cables per phase using preformed slip-on cable termination devices.Note: Width for Utility Metering Structures may vary.ATC = Automatic T ransfer Controller (see Page 8 .3-9)M = Motor OperatorPLC = Programmable Logic ControllerNote: Not to be used for construction purposes unless approved.Figure 8.3-9.

孙忠磊大唐淮南洛河发电厂安徽省淮南市 232008摘要：作为火力发电厂中非常常见的设备材料，管道、阀门在生产运行中也占据重要地位，其振动会给火力发电厂的正常运转带来影响。
本文在简述管道阀门振动危害的基础上，对管道阀门振动类型进行了简要分析；在简述管道阀门振动治理原则的基础上，对管道阀门振动对策进行了探索，以促进火力发电厂的正常、稳定运转。
关键词：管道；火力发电厂；阀门前言目前，火力发电厂的运行原理基本都是通过加热燃烧燃料带动水蒸汽，借助于设定的发电设置进行电力的生产，在火力发电厂的生产系统中，管道与阀门具有着必不可少的地位。
在生产系统当中，管道起到血管作用，阀门可对系统开关进行控制。
在技术进一步发展的现在，火电单机容量得到了进一步增长，其在管道与阀门的技术和材料方面要求越来越高。
然而，受阀门管道内流体介质、运行、选型、安装、设计、构造与材料的影响，管道阀门常出现振动情况，影响其使用寿命，最终对经济效益产生影响。
在此背景下，需加强对火力发电厂管道阀门振动的研究与分析，减少其振动状况，保证其正常发挥作用。
1管道阀门振动造成的危害在对于管道与阀门的震动情况进行分析时，应从静应力与动态两个方面进行分析，其中，疲劳损害主要是构件破坏，振动响应体现在时间函数上。
根据对压力管道阀门疲劳损害的分析，其主要表现包括低循环疲劳破损与高循环疲劳破损。
致使管道阀门出现振动情况的因素种类较多，在进行应对时，应根据具体情况进行分析。
本文在进行探索的过程中，首先针对于管道阀门振动的危害进行分析，根据火力发电厂实际运行情况，管道阀门振动将导致其使用时间减少、发电系统损害、管道阀门破损以及仪器仪表的损坏。

莫克维迪轴流式调节阀
MOKVELD轴流式控制阀的特点及常见问题处理1 川气东送站场压力控制系统简介川气东送站场压力控制系统是由安全切断阀（SSV）、监控调压阀（PCV）、工作调压阀（PV）按照从上游至下游的顺序，串联在一起的安全、监控式调压系统（调压橇）。
安全切断阀OSE、监控调压阀FL、工作调压阀MOKVELD为相互独立的设备。
正常情况下，安全切断阀和监控调压阀处于全开位置，由工作调压阀对下游压力进行控制。
当工作调压阀出现故障，无法控制下游压力时，监控调压阀开始工作，以维持下游压力的安全范围。
若监控调压阀也出现故障，不能控制下游压力，安全切断阀则自动切断气源，同时控制机柜开启备用回路，以保证下游管道和设备的安全。
当需要进行流量控制时，控制机柜接到SCADA系统的信号，供气流量超过设定值时，控制机柜和工作调压阀则切换到流量控制状态，此时控制机柜输出控制信号，限制分输流量，见图1。
图1 川气东送站场压力控制系统2 MOKVELD控制阀2.1 MOKVELD控制阀的结构MOKVELD控制阀是一种轴流式调节阀，由阀外体、阀内体、阀杆、活塞杆、活塞和笼筒组成，见图2。
阀体包括阀外体和阀内体，是一完整的铸造体，阀的内外体之间有一轴向对称流道，见图2箭头处。
笼筒是减压阀的关键部件，壁面上有许多孔洞，MOKVELD控制阀选用三层笼筒，即笼筒壁面分三层，每层按一定规律分布有许多孔洞，三层壁面按一定的要求组合为一体。
活塞杆与阀杆构成一个90°的角式传动机构（见图2），活塞借助此传动机构在导轨内沿阀门的中心线运动，活塞杆与阀杆上4 5°的齿条相互啮合，阀杆上下传动，带动活塞杆及活塞在全行程上左右运动。
活塞的端面上均匀分布有孔洞，以使活塞内外压力平衡，左右运动时不受轴向压力的影响。
