标准摘要
[中文适用范围]: 本部分IEC 62146系列适用于断路器上使用的分级电容器。其功能是控制多断口断路器中各断口单元之间的电压分布。分级电容器也可用于单断口断路器的断口单元并联,以修改瞬态恢复电压(TRV)。分级电容器是断路器的一个子组件,应根据断路器规范进行规定。本标准适用于以下一种或两种类别的分级电容器:安装在空气绝缘断路器上;安装在封闭式断路器上(例如浸入SF6、油等)。上述每种应用的测试在某些情况下是不同的。本标准的目的是:定义关于性能、测试和评级的统一规则;定义特定的安全规则;提供安装和操作指南。注:CIGRE技术手册368对应用于高压断路器的电压分级电容器的工作环境进行了研究。本标准不适用于安装在断路器上用于修改瞬态恢复电压的相地电容器。 [外文原描述]: IEC 62146-1:2013+A1:2016 is applicable to grading capacitors used on circuit-breakers. Their function is to control the voltage distribution across the individual interrupter units of a multi-break circuit-breaker. Grading capacitors can also be used in parallel to the interrupter unit on single break circuit-breakers to modify the Transient Recovery Voltage (TRV). The grading capacitor is a sub-component for the circuit-breaker and shall be specified in accordance with the circuit-breaker specifications. This standard applies to grading capacitors falling into one or both of the following categories for: - mounting on air-insulated circuit-breakers; - mounting on enclosed circuit-breakers (for example immersed in SF6, in oil, etc.). The testing for each of the above applications is in some cases different. The object of this standard is: - to define uniform rules regarding performances, testing and rating; - to define specific safety rules; - to provide a guidance for installation and operation. Keywords: grading capacitors, circuit-breakers This consolidated version consists of the first edition (2013) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.
