IEC 62271的本部分适用于额定最大电压高于1000 V，小于等于38 kV的所有架空、垫装、干式拱顶和潜水式单极或多极交流自动电路重合器。本文件不包括需要独立手动操作的设备。为了尽可能简化本文件，用术语重合器代替自动电路重合器或断路器安装重合器或两者。

This part of IEC 62271 applies to all overhead, pad-mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers for rated maximum voltages above 1 000 V and up to and including 38 kV.Devices that require a dependent manual operation are not covered by this document.In order to simplify this document where possible, the term recloser (or reclosers) has been substituted for automatic circuit recloser(s) or cutout mounted recloser(s) or both.
