适用范围:
This guide provides requirements and guidance for the seismic qualification of metal-enclosed power switchgear assemblies including switching, interrupting, control, instrumentation, metering, and protective and regulating devices mounted there in. This guide may be used by equipment manufacturers to establish procedures that will yield data to substantiate performance or by equipment users to evaluate and verify performance of representative devices and assemblies as part of an overall… read more qualification effort. As used in this guide, the word switchgear shall mean metal-enclosed power switchgear assemblies with the requirements as defined in IEEE Std C37.20.1™, IEEE Std C37.20.2™, IEEE and Std C37.20.3™. By definition, metal-enclosed power switchgear assemblies include metal-clad switchgear, metal-enclosed interrupter switchgear, and low-voltage power circuit breaker switchgear. This guide does not cover metal-enclosed bus or control switchboards. read less
