变频器输入、输出端安装接触器和电抗器的作用是什么变频器_软启动器
变频器输入、输出端安装接触器和电抗器的作用是什么? - 变频器_软启动器变频器会在输入端加接触器和电抗器是正常的配置，接触器的作用就相对于是电源开关，在紧急状况下使用接触器直接来停止变频器电源，加电抗器是为了爱护整流块，对尖峰电压起平滑作用。
输出端电抗器的作用就是变频器和电机距离比较远状况下加，加接触器假如是一拖一状况下是没有必要加，且加了没有好处的，在变频器和电机是一拖二一用一备状况下是需要加接触器来转换电机的，在做把握时候需要先让接触器动作吸合后，使用接触器的常开触点作为变频器运行的条件之一。
电源侧接触器使用目的：电源一旦断电，自动将变频器与电源脱开，以免在外部端子把握状态下重新供电时变频器自行工作，以爱护设备的平安及人身平安；在变频器内部爱护功能起作用时，通过接触器使变频器与电源脱开。
使用时请留意，不要用电磁接触器进行频繁地起动或停止（变频器输入回路的开闭寿命大约为10万次），不能用电源侧的电磁接触器停止变频器选择合适的电抗器与变频器配套使用，既可以抑制谐波电流，降低变频器系统所产生的谐波总量，提高变频器的功率因数，又可以抑制来自电网的浪涌电流对变频器的冲击，爱护变频器、降低电动机噪声。
保证变频器和电动机的牢靠运行。

Trench的电抗器产品介绍
ReactorsIntroductionWith 40 years of successful field experience, Trench is the recognized world leader in the design and manufacture of air core, dry type, power reactors for all utility and industrial applications. The unique, custom design ap-proach, along with fully integrated engineering and manufacturing facilities in both North America and Europe have enabled Trench to become the technical leader for high voltage inductors worldwide.A deep commitment to the power industry, along with extensive investment in engineering, manufacturing and test capability give Trench customers the utmost in high quality, reliable products which are individually designed for each application. Trench reactor applications have grown from small, distribution class, current limiting reactors to complex EHV applied reactors surpassing 300 MVA per coil. Reactors are manufactured in accordance with ISO 9001 quality standard. Trench's highly develo-ped research and development program constantly addresses new technologies and their potential ap-plication in reactor products. Trench welcomes challenges for new applications for power reactors.This brochure outlines the features, capabilities and applications of Trench reactors.Although air-core, dry type reactors represent the majority of reactor production volume, Trenchalso produces a highly successful line of iron core/iron shielded and oil type reactors for specific appli-cation (eg. Resonance Grounding/ Petersen Coils). These reactors are also described in detail in other sections of the Trenchproduct catalogue.Design Features ofAir-Core Dry Type Reactors•Epoxy impregnated, fibreglass encapsulated construction•Aluminum construction through-out with all current carrying connections welded•Highest mechanical and short circuit strength•Essentially zero radial voltage stress, with uniformly graded axial voltage distribution between terminals•Low noise levels are maintained throughout the life of the reactor•Weatherproof construction, with minimum maintenance require-ments•Design service life in excess of 30 years•Designs available in compliance with ANSI/IEEE, IEC and othermajor standards.ReactorsFig. 1Three-phase stackedcurrent limiting reactor 2Series ReactorsReactors connected in series with the line or feeder. Typical uses are fault current reduction, load balancing in parallel circuits, limi-ting inrush currents of capacitor banks, etc.Reactor ApplicationsFig. 2Schematic diagramFig. 4Current limiting reactorFig. 3Single phase series reactors Trench reactors are utilized on transmission anddistribution systems. Although it is not possible to list all reactor applications, some of the most common are described below.Current Limiting Reactors,reduce the short circuit current to levels within the rating of theequipment on the load side of the reactor.Applications of current limiting reactors range from the simple distribution feeder reactor to large bus-tie and load balancing reactors on systems rated up to 765 kV/2100 kV BIL.Capacitor Reactors are designed to be installed in series with ashunt connected capacitor bank to limit inrush currents due toswitching, to limit outrush currents due to close in faults and to control the resonant frequency of the system due to the addition of the capacitor banks. Reactors can be installed on system voltages through 765 kV/2100 kV BIL. When specifying capacitor reactors,the requested continuous current rating should account for harmonic current content, tolerance on capacitors and allowable system overvoltage.3Buffer Reactors forElectric Arc Furnaces (EAF).The most effective use of EAFs is achieved by operating the furnace at low electrode current and long arc length. This requires the use of a series reactor in the supply system of the arc furnace transformer forstabilizing the arc.Fig. 5 Buffer reactor for E.A.F.Fig. 6Load flow control reactors Duplex Reactors are currentlimiting reactors which consist oftwo half coils, wound in opposition.These reactors provide a desirablelow reactance under normal con-ditions and a high reactance underfault conditions.Load Flow Control Reactors areseries connected on transmissionlines up to 800 kV.The reactors change the lineimpedance characteristic such thatload flow can be controlled, thusensuring maximum power transferover adjacent transmission lines.4Filter ReactorsFilter Reactors are used in conjunc-tion with capacitor banks to form series tuned harmonic filter circuits, or in conjunction with capacitor banks and resistors to form broad-band harmonic filter circuits.When specifying filter reactors, the magnitudes of fundamental and harmonic frequency current should be indicated. If inductance adjustment for fine tuning is required, the required tapping range and tolerances must be specified. Many filter applications require a Q-factor which is very much lower than the natural Q of the reactor. This is often achieved by connecting a resistor in the circuit.An economical alternative is the addition of a de Q'ing ring structure on a reactor. This can reduce the Q-factor of the reactor by as much as one tenth without the necessity of installing additional damping resistors. (see Fig. 9 below) These rings, mounted on the reactorare simply coupled to the magneticFig. 8Filter reactorsFig. 9Filter reactors withde Q’ing ringsFig. 7Schematic diagramFig. 10Capacitor/filter protection relayfield of the reactor. This eliminatesthe concern of space, connectionand reliability of additional compo-nents such as resistors.The Capacitor/Filter ProtectionRelay CPR 97is a microprocessorbased protection relay speciallydesigned for optimized protectionof shunt banks and harmonic filtercircuits.5Static VAR Compensators are used on transmission systems to improve the overall reliability, correct for voltage fluctuations and power factor as well asincreasing the transmission capability and reducing losses.Shunt ReactorsShunt Reactors are used to compensate for capacitive VARs generated by lightly loaded trans-mission lines or undergroundcables. They are normally connected to the transformer tertiary winding but can also be directly connected on systems up to 115 kV.Fig. 11Schematic diagramFig. 14Thyristor controlled reactorFig. 12Tertiary connected shunt reactorsFig. 13Thyristor controlled shunt reactors and filterreactors in a Static VAR CompensatorThyristor ControlledShunt Reactors are extensively used in static VAR systems, where reactive VARs are adjusted by thyristor circuits. Static VARcompensator reactor applications normally include:•Thyristor controlled shunt reactors (TCR). The compensating power is changed by controlling the current through the reactor by means of the thyristor valves.•Thyristor switched reactors (TSR)•Thyristor switched capacitor reactors (TSC)•Filter reactors (FR)6HVDC-ReactorsHVDC lines are used for longdistance bulk power transmissionFig. 15SchematicdiagramFig. 17HVDC-Smoothing reactorFig. 16AC-Filtersas well as back-to-back inter-connections between differenttransmission networks.HVDC Reactors normally includeSmooting Reactors, AC and DCHarmonic Filter Reactors as wellas AC and DC PLC Noise FilterReactors.7Smoothing ReactorsSmoothing reactors are used to reduce the magnitude of the ripple current in a DC system. They are used in power electronics applications such as variable speed drives and UPS systems. They are also required on HVDC transmission lines for system voltages up to 500 kV.Several design and construction techniques are offered by Trench.Fig. 18 Schematic diagramFig. 19Iron core, forced air cooled reactorFig. 20Air core,encapsulated winding designFig. 21Iron core,water cooled reactor8Test Lab ReactorsTest Lab Reactors are installed in high voltage and high power test laboratories. Some typical applications include current limiting, synthetic testing of circuit breakers, inductive energy storage, artificiallines, etc.Fig. 22Schematic diagramFig. 23Reactor bank for thevoltage circuit for synthetic testingof circuit breakers;32 kA peak to peak,0,318 mH to 353,6 mH,up to 1600 kV BILFig. 25Short circuittest reactorFig. 24Adjustablecurrent limiting reactor9Neutral Grounding ReactorsNeutral Grounding Reactors limit the line to ground fault current to specified levels. Specification should also include unbalanced condition continuous current andduration.Fig. 26Schematic diagramFig. 27Arc suppression coil 110 kV Fig. 28Standard arc suppression coilArc Suppression CoilsSingle-phase neutral grounding (earthing) reactors (arc suppression coils) are intended to compensate for the capacitive line-to-ground current during a single phase gro-und-fault.The arc suppression coil (ASC) represents the central element of the Trench earth fault protection system.Since the electric system is subject to changes, the inductance of the ASC used for neutral earthing must be variable.The earth fault detection system developed by Trench utilizes the plunger core coil (moveable core design). Based on extensive experi-ence in design, construction and application of ASCs, Trenchproducts can meet the most strin-gent requirements for earth fault compensating techniques.10A Trench air core dry type reactor consists of a number of parallel connected, individually insulated, aluminum (copper on request) conductors. These conductors can be small wire or proprietary cables custom designed and manufactured.The size and type of conductor used in each reactor is dependant on the reactor specification. The various styles and sizes of conductors available ensure optimum performance at the most economical cost. The windings are mechanically reinforced with epoxy resin impregnated fibreglass, which after a carefully defined oven cure cycle produces an encapsulated coil. A network of horizontal and vertical fibreglass ties coupled with the encapsulation minimizes vibration in the reactor and achieves the highest available mechanical strength.The windings are terminated at each end to a set of aluminum bars called a spider. This construction results in a very rigid unit capable of withstanding the stresses developed under the most severe short circuit conditions. Exceptionally high levels of terminal pull, tensile strength, wind loading and seismic withstand can be accommodated with the reactor. See Fig. 29 for details on construction.This unique design can be installed in all types of climates and environments and still offer optimum performance.Trench air core dry typereactors are installed in polluted and corrosive areas supplying trouble free operation. In addition to the standard fixed reactance type of coil, units can be supplied with taps for variable inductance.A number of methods are available to vary inductance for fine tuning or to provide a range of larger inductance steps.Trench utilizes various other designs for reactors (eg. iron core, water cooled, etc.) which are described in other sections of thiscatalogue.ConstructionFig. 29Typical Trench air core dry typereactor construction11It is the customer's responsibility to consider these minimum clearances, especially if steelreinforcing in concrete foundations or floors, or structural steel is involved in the building or station design. It is important, even outside these minimum magnetic clearan-ces, to avoid closed electrical loops with metallic parts.Terminals/Magnetic ClearanceIf required, non-magnetic extension brackets can be supplied by Trench to maintain thenecessary magnetic clearance below the reactor. Trench canprovide additional details on space requirements andrecommended reinforcing steel (rebar) design, if requested.Magnetic ClearanceMinimum clearances to metallic parts, and between coils, must be maintained as indicated by Figs. 32and 33. The values shown are only guidelines. Each specific reactor design will specify magnetic clearance requirements.Fig. 30Terminal orientation Fig. 31Terminal detailsMinimum magnetic clearance to other reactors and metallic partsnot forming closed loops (approximate values only)Terminals12Generally, air core, dry type reactors can be installed in either side by side or vertically stacked configurations and are often added to existing substations or locations where space limitations exist. With its highly developed computer design expertise, Trench can design reactors with optimized dimensions, to suit limited space requirements. The multi-spider construction allows flexibility in terminal location, which minimizes connection problems (see Fig. 35).Number of spider arms to be obtained from the actual quotation design.Installation assembly is minimal and typically requires only that brackets and insulators be bolted to the main coil. Installation instructions are provided with each reactor order.Trench takes intoconsideration all aspects of the reactor installation. These include requirements of ventilation, reactor supports, connections and busbar arrangements.Trench can also provide detailed information regarding:•magnetic field distribution analysis for mounting pads and foundations, grounding grids, fences and adjacent structures•Force calculations on adjacent coil installations, bus and cable connectionsInstallation•Seismic analysis on entire reactor assemblies, including support insulators and mounting pedestals, when furnished.Fig. 33Three-phasestacked arrangement13TestingAt Trench each reactor manufactured is subjected to a rigorous test and inspection program. In addition to the routine testing required by ANSI/IEEE or IEC a number of in-process tests are performed on each unit during production to ensure maximum in-service reliability. Each reactor is supplied with a certified test report with the results from all tests performed.In addition to routine testing we have the capability in our High Voltage and Power labs to perform most of the design tests described in the applicable standards. Design tests can be performed at an additional cost or test reports on similar units can be supplied upon request.The materials used in the manufacture of the reactor are also subject to a strict test program. Cooling duct spacers and the fibreglass epoxy resin composite encapsulation are subject to routine mechanical strength and tracking resistance testing. Accelerated thermal and multifactor aging studies are carried out which help to verify performance of the reactor components over their full service life.This testing coupled with our Quality Assurance program enables us to ensure the continuous perfor-mance of our reactors throughout the design service life.LossesThe custom design approach used by Trench allows optimum use of materials to control reactor losses. If a loss evaluation is not indicated in the specification, the reactor will be designed to meet the applicable standards at a most economical initial cost.All customers are aware of the advantages in minimizing system losses and are applying loss evaluation techniques to reactor purchases. In the cases where loss evaluations are included in the reactor specifications, Trench optimizes the initial cost of the reactor plus the cost of operating losses, to ensure the most economical balance. Generally, a loss optimized reactor will operate at a lower temperature rise and will thus extend the reactor overload capability.Trench's ability to design and manufacture low loss reactors al-lows many electric power utilities to economically justify the replacement of older, inefficient reactor installations. The low loss reactors can usually be installed on existing mounting pads.Losses can also be influenced for other purposes. In some applications it is important to control the Q factor (X/R ratio) of the reactor. This may be important at the fundamental frequency or at specific harmonic frequencies where additional losses are advantageous, for example capacitor switching reactors and certain filter applications.Testing/LossesFig. 34High voltage test laboratory 14Trench designs andmanufactures enclosures and support pedestals specifically for air core, dry type reactors.Enclosures, depending on the requirement, are made of steel or fibreglass and can be designed for indoor or outdoor installations.Trench enclosure design minimizes circulating current loops and opti-mizes the size by defining ventila-tion area and acceptable tempe-rature rise. Enclosures have been qualified as completeassemblies by short circuit testing of the enclosed reactor.Trench can supply support pede-stals to elevate reactor live parts to a height commensurate with per-sonnel safety standards. Pedestals also provide propermagnetic clearance below the reactor.Various pedestal designs are available and include fibreglass,braced aluminum and non-magnetic steel designs.Trench can recommend the most practical pedestal for each reactor application. Additional information on enclosures and pedestals is available on request.Sound shields can be provided to reduce the reactor noise level for special applications (HVDC).Enclosures and PedestalsFig. 35Filter reactor with sound shieldFig. 36Filter reactor with top-hatand pedestal15Data required with order•Reactor application•Indoor or outdoor installation•System voltage,impulse insulation level (BIL)•Rated and maximum continuous current (fundamental and harmonics)•Short circuit current level and duration•Rated inductance/impedance•Mounting arrangement (side by side or vertical stack)•Detailed accessory requirements (connectors, buswork, etc.)•Location of installation and site conditions•Ambient temperature range Trench Austria GmbH Paschinger Strasse 49, Postfach 13 A-4060 Linz-Leonding/Austria Phone+43.732.6793-0Fax+43.732.671341E-Mail sales@TrenchAustria.at Trench Brasil LTDAVia Expressa de Contagem, 2685 CEP 32370-485Contagem, MG - BrasilPhone 55. 31. 391-5959Fax 55. 31. 391-1828E-mailtrenchbrasil@ Trench LimitedCoil Product Division71 Maybrook Drive, Scarborough Ontario, Canada M1V 4B6 Phone (416) 298-8108Fax (416)298-2209E-Mail sales@ Trench LimitedInstrument Transformer Division 390 Midwest Road, Scarborough Ontario, Canada M1P 3B5Phone (416) 751-8570Fax (416)751-6952E-Mail sales@ Trench France S.A.16, rue du Général Cassagnou B.P. 70F-68302 St-Louis Cedex/France Phone +33.3.8970 23 23Fax +33.3.89 67 26 63E-Mail sales@ Trench Germany GmbHNürnberger Strasse 19996050 Bamberg/GermanyPhone +49.951.1803-0Fax +49.951.1803-224E-Mail sales@trench.deTrench Switzerland AG Lehenmattstrasse 353CH-4028 Basel/Switzerland Phone +41.61.315 5111Fax +41.61.315 59 00E-Mail sales@trench.chSubject to change without notice04.2000E 600。

目前市场上运用广泛的主要有以下两类：变频器用电抗器和无功补偿用电抗器。
变频器用电抗器主要分为：输入电抗器（又叫进线电抗器）、输出电抗器（又叫出线电抗器）以及直流电抗器（又叫平波电抗器或者DC电抗器）。
无功补偿用电抗器主要分为：解谐电抗器（又叫消谐电抗器或者串联电抗器)和滤波电抗器！其他电抗器还有限流电抗器、阻尼电抗器等等。

TCR+FC型SVC静止动态无功补偿装置简介
TCR+FC型SVC静止动态无功补偿装置简介随着国民经济的发展和现代化技术的进步，电力网负荷急剧增大，对电网无功功率的要求与日俱增。
特别是如轧机、电弧炉等冲击、非线性负荷的不断增加，加上电力电子技术的普遍应用，使得电力网发生了电压波形畸变、电压波动闪变和三相不平衡等，产生了电能质量降低、网络损耗增加等不良影响。
因此解决好电网的无功功率因数补偿和谐波滤波问题，对于提高电能质量、安全运行、降低损耗、节能、充分利用电气设备的出力等具有重要的意义。
1、谐波的危害：1.电能的生产，传输和利用效率降低，电器设备过热，产生附加的振动和噪声2.绝缘老化，寿命缩短3.设备故障，引起电力系统局部发生串联谐振或者并联谐振4.谐波发生放大，造成电容器过热，膨胀甚至产生破裂5.继电保护和自动化控制装置误动作，使电能计量失准，造成混乱6.对通信和电子设备产生干扰。
2、简介90年代以来，随着高压晶闸阀的制造技术日趋成熟，绝大部分用户采用TCR+FC型SVC这种动态无功补偿及滤波装置来改善电网电能的质量。
晶闸管控制电抗器型静止动态无功补偿装置是一种可以自动调节的无功功率补偿装置。
它具有3个主要功能：抑制电压波动，改善功率因数，吸收电网谐波。
TCR+FC型SVC全称如下：图1：TCR+FC型SVC主回路接线图无源单调谐滤器FC以其结构简单、成本低、运行维护方便等特点被广泛应用于负荷冲击不大的有污染的供电系统中，具有吸收电网谐波和补偿无功功率两个功能。
安装于母线或者设备侧，设备组合方便，性能稳定。
TCR（Thyristor Controlled Reactor）是晶闸管投切电抗器型静止无功补偿装置。
由于单独的TCR只能吸收感性的无功功率，因此往往与并联电容器配合使用。
并联电容器后，使得总的无功功率为TCR与并联电容器无功功率抵消后的净无功功率。
3、TCR型补偿装置工作原理TCR型动补装置的补偿原理见图2所示。
图中Q C为电容器功率，Q L为负载感性无功功率，Q LS为补偿器所提供的感性无功功率。

电抗器厂家直销价格优惠！输入电抗器输入电器器英文名称Input AC reactor 变频器的输入端安装JXL输入电抗器，一方面是为了减小谐波电流发射，另一方面可以提高变频器抗浪涌干扰的特性。
变频器的整流电路相当于一个谐波电压源。
我们知道，电压源当负载阻抗大时，输出电流会小。
因此，在变频器的电源输入端安装电抗器能够减小谐波电流的发射。
输出电抗器输出电抗器英文名称Output reactor ，当变频器输出到电机的电缆长度大于产品规定值时，应加输出电抗器来补偿电机长电缆运行时的耦合电容的充放电影响，避免变频器过流。
变频器输出端增加输出电抗器的作用是为了增加变频器到电动机的导线距离，输出电抗器可以有效抑制变频器的IGBT开关时产生的瞬间高电压，减少此电压对电缆绝缘和电机的不良影响。
直流电抗器直流电抗器英文名称 DC Reactors 直流电抗器接在变频系统的直流整流环节与逆变环节之间，主要用途是将叠加在直流电流上的交流分量限定在某一规定值,保持整流电流连续，减小电流脉冲值,使逆变环节运行更稳定及改善变频器的功率因数串联电抗器串联电抗器LV-Series Reactors 低压串联电抗器适用于无功补偿系统中的电容器前端，抑制电网中的谐波，保护电容器的正常使用CKSG串联电抗器并联在电网中,低频时呈现容性,主要起到无功补偿功能;高频时,电网呈现感性,从而抑制谐波起动保护电容器的作用。
高压串联电抗器高压串联电抗器HV-Series Reactors 与并联电容器相串联，具有补偿电网无功功率、提高功率因数、抑制谐波电流、限制合闸涌流等功能，高压串联电抗器适用于电力系统、电力化铁道、冶金、石化等较高防火要求、电磁干扰要求和安装空间有限的城网变电站、地下变电站和微机控制变电站等场所哈尔滨电抗器作用1-1，哈尔滨电抗器-输入电抗器（Input AC reactor）作用■减少对电网的低次谐波污染，提高功率因数■限制变流器换相时电网侧的压降■限制晶闸管导通时电流上升率di/dt和电压上升率du/dt■对并联变流器解耦，改善电源电压的波形■减少浪涌电流和电压对变流器的冲击，提高变频系统可靠性和使用寿命1-2哈尔滨电抗器-输出电抗器（Output reactor ）作用1、降低工频暂态过电压，这是利用变频器专用出线电抗器的空载或轻负荷线路上的电容效应来实现的；2、改善长输电线路上的电压分布；3、缓解变频器输出端的三相不平衡现象，减轻线路上的能量损失；使轻负荷时线路中的无功功率尽可能就地平衡，防止无功功率不合理流动；4、降低高压母线上工频稳态电压，便于发电机同期并列；5、防止发电机带长线路可能出现的自励磁谐振现象。
1-3哈尔滨电抗器-直流电抗器-DC Reactors作用因为脉动的直流输出电压中所包含的谐波分量，在逆变时将产生不必要的损耗和发热，谐波中的负序分量则产生反向力矩，而且当晶闸管深控时，若脉动的直流输出电压的瞬时值低于电动机的反电势，将使电流不连续。
整流电路的脉波数总是有限的，且在输出的直流电压中总是有纹波的，这种纹波往往有害，需要由平波电抗器加以抑制，平波电抗器用于整流以后的直流回路中，经平波电抗器后输出的直流接近于理想直流。
