High-voltage switchgear and controlgear. Part 205: Compact switchgear assemblies for rated coltages above 52 kV (IEC 62271-205:2008)

Alkalmazási terület

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 between 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 components 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 assemblies 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 interactions 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 The 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 envisaged. 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: Switching devices: • Circuit-breakers IEC 62271-100 • Disconnectors/Earthing switches IEC 62271-102 • Switches IEC 60265-2 • Disconnecting circuit-breakers IEC 62271-108 Devices: • 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 61639 Each switching device, device and their controlgear forming part of a compact switchgear assembly shall comply with the relevant individual standard. If part of the compact switchgear assembly is formed by metal enclosed switchgear devices the requirements of IEC 62271-203 apply. Compact switchgear assemblies, as defined in this standard, are considered to be a single product with a single serial number and one set of documentation.
