高压电容器交流电压电路断路器.第2部分:TRV电容器

[中文适用范围]： 本部分IEC 62146适用于额定电压高于100 kV的高压交流断路器上使用的TRV电容器，频率为50 Hz或60 Hz。TRV电容器安装于相与地之间，可以并联于死罐断路器的套管上，或浸入断路器内部，或独立安装于断路器附近。其功能是限制断路器上的瞬态恢复电压(TRV)和恢复电压上升率(RRRV)。符合本文件的电容器可用作TRV电容器。本文件适用于以下一种或两种应用类别的TRV电容器：安装在空气绝缘开关设备(AIS)死罐和活罐断路器上或附近，或安装在气体绝缘开关设备(GIS)断路器上。每种应用的测试在某些情况下有所不同。本文件不适用于与断路器并联安装的分级电容器（在IEC 62146-1中规定），也不适用于与高压交流断路器不直接相关的电容器。本文件的目的是：规定性能、测试和评级的统一规则；规定具体的安全规则；提供安装和操作指南。TRV电容器是断路器的子组件，根据IEC 62271-1、IEC 62271-100和IEC 62271-203的断路器规范进行规定。TRV电容器通常采用复合或陶瓷外壳（绝缘子）制造。这些绝缘子遵循IEC 61462或IEC 62155。如果其他外壳能承受IEC 61462和IEC 62155规定的适用型式测试，也可以使用。 [外文原描述]： IEC 62146-2:2023 is applicable to TRV capacitors used on high-voltage alternating current circuit-breakers with rated voltages above 100 kV with 50 Hz or 60 Hz. TRV capacitors are installed phase to earth, either in parallel to the bushing on dead tank circuit-breakers, or immersed inside the circuit-breaker, or freestanding close to the circuit-breaker. Their function is to limit the transient recovery voltage (TRV) and the rate of rise of recovery voltage (RRRV) on the circuit-breaker. Capacitors in compliance with this document can be used as TRV capacitor. This document applies to TRV capacitors falling into one or both of the following categories for: - mounting on or close to air insulated switchgear (AIS) dead tank and live tank circuit-breakers, or - mounting on gas insulated switchgear (GIS) circuit-breakers. The testing for each of the above applications is in some cases different. This document does not apply to grading capacitors installed in parallel to the chambers of the circuit-breaker, which are specified in IEC 62146-1. This document does not apply to capacitors not directly associated with high-voltage alternating current circuit-breakers. The object of this document is: - to define uniform rules regarding performances, testing and rating - to define specific safety rules - to provide a guidance for installation and operation The TRV capacitor is a sub-component for the circuit-breaker and is specified in accordance with the circuit-breaker specifications according to IEC 62271-1, IEC 62271-100, and if applicable to IEC 62271-203. TRV capacitors are commonly built with composite or ceramic housings (insulators). Those insulators follow IEC 61462 or IEC 62155. Other housings can be used if they can sustain applicable type tests according to IEC 61462 and IEC 62155. This International Standard is to be used in conjunction with IEC 62146-1:2013 and IEC 62146-1:2013/AMD1:2016.
