24、t switchgear assemblies for rated voltages above 52 kV 1 General 1.1 Scope This part of IEC 62271 applies to compact switchgear assemblies consisting of at least one switching device directly connected to, or sharing components with, one or more other devices such that there is an interaction betwee
25、n the functions of the individual devices. Such assemblies are made up of devices defined in 1.101 and are designed, tested and supplied for use as a single unit. The interaction between devices may be due to proximity, sharing of components or a combination of both. The assemblies may contain compo
26、nents of air insulated 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 or partially assembled. It is not possible to define all potential arrangements of compact switchgear assem
27、blies however four examples are shown for information in Annex A. These compact switchgear assemblies are for indoor and/or outdoor installations in systems having rated voltages above 52 kV and service frequencies of 50 Hz and 60 Hz. This standard covers the influence on performance of the interact
28、ions between devices within compact 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 are covered by 62271-203. 1.101 Objective Th
29、e objective of this standard is to respond to the increasing use of compact switchgear assemblies 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 of assemblies which might be envis
30、aged. As there are potential interactions between devices within such assemblies, it is necessary to consider the standardization requirements for the assembly in its entirety. The devices, defined by IEC standards, which may form part of a compact switchgear assembly are listed below: BS EN 62271-2

44、16-25 BS EN 62271-205:2008 7 3.1.102 disconnected position (of a withdrawable part) position of a withdrawable part in which an isolating distance or segregation is established in all the circuits of the withdrawable part, that part remaining mechanically attached to the assembly IEV 441-16-28 NOTE
45、1 The auxiliary circuits may not be disconnected in this position. NOTE 2 This position may not be one in which it is safe to work on the withdrawn (moved) part. 3.2 Compact switchgear assembly Subclause 3.2 of IEC 62271-1 is applicable with the following addition: A compact switchgear assembly cons
46、ists of at least one switching device directly connected to, or sharing components with, one or more other devices such that there is an interaction between the functions of the individual devices. NOTE 1 A compact switchgear assembly may be mounted on one or more structures but it is only intended
47、for installation and operation as a single, complete unit. NOTE 2 Interaction is the transfer of stresses (e.g. electrical, mechanical and thermal) between the individual devices. 4 Rating Clause 4 of IEC 62271-1 is partly applicable with the following distinctive features: The rating of a compact s
48、witchgear assembly and its controlgear comprise the following : a) rated voltage (Ur); b) rated insulation level; c) rated frequency (fr); d) rated normal current (lr) (for main circuits); e) rated short-time withstand current (Ik) (for main and earthing circuits); f) rated peak withstand current (I
