適用范圍：This part of IEC 62271 applies to compact switchgear assemblies consisting of at least oneswitching device directly connected to, or sharing components with, one or more otherdevices such that there is an interaction between the functions of the individual devices. Suchassemblies are made up of devices defined in 1.101 and are designed, tested and suppliedfor use as a single unit. The interaction between devices may be due to proximity, sharing ofcomponents or a combination of both. The assemblies may contain components of airinsulated switchgear (AIS) only or a combination of AIS and gas insulated switchgear (GIS),so called mixed technology switchgear (MTS) and may be delivered entirely prefabricated orpartially assembled.It is not possible to define all potential arrangements of compact switchgear assemblieshowever four examples are shown for information in Annex A.These compact switchgear assemblies are for indoor and/or outdoor installations in systemshaving rated voltages above 52 kV and service frequencies of 50 Hz and 60 Hz.This standard covers the influence on performance of the interactions between devices withincompact switchgear assemblies and defines ratings and test procedures for these assemblies.IEC 62271-1 is applicable if not stated otherwise.This standard does not apply to switchgear assemblies consisting solely of GIS which arecovered by 62271-203.1.101 ObjectiveThe objective of this standard is to respond to the increasing use of compact switchgearassemblies that perform the functions of a number of separate devices and their controlgear.Numerous arrangements are possible and this standard provides guidance on basic types ofassemblies which might be envisaged.As there are potential interactions between devices within such assemblies, it is necessary toconsider the standardization requirements for the assembly in its entirety.The devices, defined by IEC standards, which may form part of a compact switchgearassembly are listed below:Switching devices:? Circuit-breakers IEC 62271-100? Disconnectors/Earthing switches IEC 62271-102? Switches IEC 60265-2? Disconnecting circuit-breakers IEC 62271-108Devices:? Instrument transformers– Current transformers IEC 60044-1, IEC 60044-8– Voltage transformers IEC 60044-2, IEC 60044-5, IEC 60044-7– Combined transformers IEC 60044-3? Surge arresters IEC 60099-4? Bushings IEC 60137? Insulators IEC 61462, IEC 62155? Cable connections IEC 62271-209? Transformer connections IEC 61639Each switching device, device and their controlgear forming part of a compact switchgearassembly shall comply with the relevant individual standard. If part of the compact switchgearassembly is formed by metal enclosed switchgear devices the requirements of IEC 62271-203apply.Compact switchgear assemblies, as defined in this standard, are considered to be a singleproduct with a single serial number and one set of documentation.
