标准摘要
[中文适用范围]： 本部分是用于交流l000V及以下或直流1500V及以下供电线路、通信及信号系统中用来保护 设备、人员或两者免受高的瞬态电压的危害的金属氧化物压敏电阻的试验规范。 本规范适用于双电极MOV，不适用于混合装置。本规范也不考虑零配件及其安装对MOV特性的 影响。所给出的特性仅适用于按试验所述的方式安装的MOV。 [外文原描述]： Details the test specifications for metal oxide varistors (MOV), which are used for applications up to 1000 V a.c. or 1500 V d.c. in power line, or telecommunication, or signalling circuits. The MOVs are designed to protect apparatus or personnel, or both from high transient voltages. Does not deal with hybrid devices. Does not apply also to mountings and their effect on the MOVs characteristics.
