标准摘要
[中文适用范围]： IEC 62146 系列的这一部分适用于断路器上使用的均压电容器。它们的功能是控制多断路断路器的各个断续单元的电压分布。分级电容器还可与单断路断路器上的断续器单元并联使用，以修改瞬态恢复电压 (TRV)。均压电容器是断路器的一个子部件，应按照断路器规范进行规定。本标准适用于属于以下一类或两类的均压电容器： ?C 安装在空气绝缘断路器上； ?C 安装在封闭式断路器上（例如浸入油中的 SF6@ 等）。在某些情况下，上述每个应用程序的测试都是不同的。该标准的目的是： ?C 定义有关性能@测试和评级的统一规则； ?C 定义具体的安全规则； ?C 提供安装和操作指导。 [外文原描述]： IEC 62146-1:2013 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
