Scope

本文件规定了高压交流断路器用均压电容器的使用条件、额定值、设计和结构、试验、运输、贮存、安装、运行和维护规则、安全、环境方面的内容。
本文件适用于与断路器断口相并联的均压电容器。其作用是改善多断口断路器各个灭弧室单元两端的电压分布。
均压电容器也能与单断口断路器上的灭弧室单元并联使用,以抑制瞬态恢复电压(TRV)。
均压电容器是断路器的组部件且应符合断路器的技术要求。
本文件适用于满足下列类别中的一种或两种均压电容器:
——安装在空气绝缘断路器上;
——安装在封闭式断路器上。
对以上不同类别均压电容器的试验在某些情况下是不同的。
本文件的目的是:
——规定性能、试验和额定值的统一规则;
——规定特定的安全规则;
——提供安装和运行导则。
本文件不适用于安装在断路器上以抑制瞬态恢复电压的相对地电容器。
