At low flow rates the majority of the air flows through the Venturi section (A). The rest of the air opens the check valve (C). The velocity of the air flowing through the Venturi section (A) creates a pressure drop. This lower pressure allows the oil to be forced from the reservoir through the pickup tube (B) and travels up to the metering screw (D). The rate of oil delivery is then controlled by adjusting the metering screw (D). Oil flows past the metering screw (D) and forms a drop in the nozzle tube (E). As the oil drops through the dome (F) and back into the Venturi section (A), it is broken up into fine particles. It is then mixed with the air flowing past the check valve (C) and is carried downstream. As the air flow increases the check valve (C) will open more fully. This additional flow will assure that the oil delivery rate will increase linearly with the increase of air flow.Technical InformationWeight ........................................................................1.9 lb.

LVPECL is ideal for driving 50Ω and 100Ω-controlled impedance transmissionlines. There are several techniques for terminating the LVPECL output: parallel termination-Thevenin equivalent, parallel termination (3-resistor), and AC-coupled termination. Unused output pairs may be left floating. However, single-ended outputs must be terminated or balanced.Figure 10. Parallel Termination-Thevenin EquivalentNote:12.

66 Carey Road | Queensbury, NY | 12804 Ph: (518) 792-4776 | Fax: (518) 792-5767 |***************NEPSI's MSP™ (Motor Surge Protector) is de-signed to protect medium voltage motors and gen-erators from voltage surges due to lightning and switching events. The MSP™ accomplishes this task better than any other product by decreasing the slope and crest of impending voltage surges to safe levels.Application of the MSP™ is guaranteed to reduce the likelihood of motor failures, resulting in less down -time and higher productivity.GeneralMSP™ - Medium Voltage Motor Surge ProtectionFigure 1NEPSI's Medium VoltageMotor Surge Protection equip-ment protects motor insulation from power system transi-ents.Figure 2Principle operation of the MSP™ is to decrease the crest voltage and rate of rise of the impending surges. High rates of rise damage end turns while high crest voltages damage winding to core insulation. Both of these types of damaging surges are mitigated with NEPSI's MSP ™.∙Reduced medium voltage motor and generator failures from voltage surges due to lightning, faults, and switching events.∙Units can be custom designed for direct mounting to generators, mo-tor, and compressor housing.∙Units can be supplied with over -current and differential protection current transformers. Reduced downtime and material waste from motor failure.∙Simple to install andrequires no maintenance.∙MSP's are custom designed for many OEM’s utilizing medium volt-age motors and generators.Due to the wavelength and travel time of lightning and switching transients, the MSP™ is most effec-tive when placed as close as practical to the motor terminals with the ground leads being as short as possible. This will limit the surge voltage seen by the motor to the discharge voltage of the arrester. For best protection, one MSP™ should be placed at each medium voltage motor or generator. Where there are many small motors or explosion proof mo-tors in hazardous locations, a single MSP™ at the motor control center is recommended.The proper choice of MSP™ is based on the system and/or motor voltage and the system grounding. The order guide below can be used to determine the cor-rect MSP™ for your application.Enclosure11 gauge galvanneal steel all welded construction, C2 structural steel channel base, bolted stainless steel hinged door. NEMA 1, 3R, 4X (optional), 12 | IEC IP10, IP14, IP56, IP52, NEC Class 1 & 2, Div. II designs also available.Surge CapacitorThe MSP™is equipped with hermetically sealed low-loss, low-inductance surge capacitors. Their capacitance rating is based upon the MSP™ voltage rating as shown in Table 1 below. The surge capacitor is equipped with discharge resistors that reduce the residual voltage on the capacitor to 50 volts in 5 minutes.Wall mounting flangesAllows the MSP™ to be mounted on suitable walls.Surge/Lightning ArrestersThe MSP™is equipped with heavy duty, silicone rubber housed MOV distribution class lightning arresters incorpo-rating the latest in metal oxide varistor (MOV) design tech-niques (Station Class are available as an option). The high track resistant, non-fragmenting silicone rubber housed arrester provides increased safety for personnel and equipment. The lightning arresters complies with the latest revision of ANSI/IEEE C62.11 "IEEE Standard for Metal Oxide Surge Arresters for AC Power Circuits.TerminalsThe MSP is provided with a Copper NEMA 2-hole pad for interconnection with customer wiring.Operating Temperature-40F (-40C) to +115F (+46C)Warranty1 year replacement parts per NEPSI’s Standard Warranty.FusesIncreases system and equipment reliability by re-moving a failed MSP™. Blown fuse detection is provide through a set of dry contacts to alert plan personnel of a blown fuse.Pecker-Head/Motor Terminal MountingThe MSP™ can be custom designed for direct mounting to a motor or generator to act as a termi-nal box. The equipment can be equipped with a neutral grounding resistor, differential CT’s, and ground CT to provide all fault sensing.Differential current transformersThis option is shown in Figure 3, below. The differen-tial CT’s are placed inside the MSP™ and afford the highest level of protection for the motor or generator.MSP™ Ordering GuideThe MSP ™ can be ordered by choosing the part number from the table below based on the system voltage and type of grounding. Options are ordered by adding part number suffixes.Table 1MSP ™ Standard Part NumbersFigure 3Three -line diagram of MSP™ equipped with differential current transformers and phase overcurrent transformers for connection to motor protection relays.Figure 4Approximate Layout for basic MSP ™. Layout and dimensions may change without notice. Confirm layout and dimensions at order placement.Table 3MSP Dimensions Weights and Electrical ValuesTable 2MSP Part Suffixesmary current rating of the CT where #### appears.For example, an MSP ™ for a 500 HP motor that is on a 4.16kV resistive grounded system with the wall mounting brackets would have the following part number: MSP6A0416Contact the factory or your nearest sales representa-tive for options and voltages not shown above.。
NEP998A继电保护装置在高压电动机中的应用
NEP998A继电保护装置在高压电动机中的应用【摘要】在电力生产中，电气设备举足轻重，它的可靠运行对于生产安全来说非常关键，而电动机保护设备又是电动机可靠平稳运行的主要保障，本文结合陡河发电厂6KV电机保护，对NEP998A数字式继电保护装置在电力生产中的作用。
【关键字】保护装置；电机保护；电流前言：高压电机在工业生产中应用广泛，为避免电机因故障造成损坏，继电保护装置必不可少的，继电保护人员对保护的可靠性、快速性、灵敏性也越来越重视。
随着科学技术的不断发展，原老式的电磁型继电器保护已经逐渐被微机综保所替代，技术也逐渐成熟。
NEP998A型数字式继电保护装置在陡河发电厂6KV电机开关保护中广泛应用，在安全生产中起到了重要作用。
NEP998A型数字式继电保护装置，需要220V直流电源供电，采用高速处理器，主频220HZ，外围电路设计简单；测量三相电流和零序电流（Ia，Ib，Ic，Io），三相或线电压（Uan，Ubn，Ucn，Uab，Ubc，Uca）；保护元件的出口方式可通过跳闸矩阵进行整定，所有继电器出口节点可选择为跳闸接点（自动返回）或信号接点（复归后返回）。
保护功能及原理说明（1）电流速断保护它能在最短的时间内迅速切除短路故障，减小故障持续时间，防止事故扩大。
异步电动机启动过程中电流很大，能达到5-8倍额定电流（Ie），启动时间能达到几十秒。
当任一项电流大于速断保护电流定值时，保护动作。
该保护设有“起动中速断定值”和“起动后速断定值”，起动中采用前者，按躲过电动机起动电流整定，起动结束后采用后者，按电动机自起动电流和区外出口短路时电动机最大反馈电流考虑，取电流大者。
（2）过流保护当任一相电流大于过流保护定值时，经可设定的延时时间，保护动作，动作电流一般为（1。
2-2）Ie，延时按躲过电动机起动时间整定。
此电流值小于速断保护的定值。
（3）过负荷保护由于短时过负荷不会引起系统或电力设备的安全问题，但长时间会引起系统或电力设备本身的安全或稳定问题，或用电设备的安全，故过负荷一般保护延时作用于信号和跳闸。

1 装置概述NEP 988数字式备用电源自动投切装置是在消化吸收国内外先进经验的基础上专门为发电厂、变电站开发（可与各类综合自动化配套）的产品。
该类产品将结构小巧，可在恶劣的工业环境下（如高、低温、震动、有害气体、灰尘、强电磁干扰等）长期可靠地运行。
产品可按功能就地安装，并具有远传、记忆各种操作或故障信息等功能，同时亦提供独立的中央信号空接点。
特点：●采用Motorola高性能32位单片机。
●采用一对一的方式，调试、安装及维护均非常便利。
●人机界面友好，液晶中文显示。
显示信息丰富、直观、各种操作亦非常方便。
●完善的自我诊断功能，不需人为干预，故障可定位到某集成块。
●最近100条事件记录(记录事件时间和类型)、10条事故记录（包含故障前360毫秒，故障后600毫秒，记录事故时间、类型、定值、控制字、交流量幅值及采样点）及200条遥信变位信息（记录遥信变位时间和类型），方便分析。
●高抗干扰性能，能满足：GB/T 快速瞬变干扰试验Ⅳ级GB/T 脉冲群干扰试验Ⅲ级GB/T 静电放电干扰试验Ⅲ级功能：母联备自投、进线互投、内桥开关备自投、厂用电源自投、水电厂备自投、两相三段式电流保护、过流加速段保护及各种开关量变位信息等功能。
