摘要

针对当前环保型环网柜（包括环保气体绝缘环网柜、固体绝缘环网柜）中主开关（真空断路器、真空负荷开关）与隔离接地三工位开关这2种布置方式的差异和争论

依据相关电力安全工作规程和产品标准论证了2种布置方式的差异和优缺点

得出了2种方式都满足现行规程和标准的要求

给出了明确的结论。

Abstract

Thispapermainlydescribescurrentdifferencesandargumentsabouttwoarrangmentsofmainswitch（including vacuum circuit breaker and vacuum load-break switch）with three-position switch in environmental protection ring main unit（including environmental protection gas insulated ring main unit and solid insulated ring main unit）

demonstrates the difference and the advantage of two arrangments according to relevant regulations of electric industry safety work. The two arrangments meet current regulations and standards

and a clear conclusion has been given.
