高压开关设备和控制设备第209部分:额定电压高于52kV的气体绝缘金属封闭开关设备的电缆连接充液和挤压绝缘电缆充液和干式电缆终端

[中文适用范围]： This part of IEC 62271 covers the connection assembly of fluid-filled and extruded cables to gas-insulated metal enclosed switchgear (GIS), in single- or three-phase arrangements where the cable terminations are fluid-filled or dry-type and there is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear. The purpose of this document is to establish electrical and mechanical interchangeability between cable terminations and the gas-insulated metal-enclosed switchgear and to determine the limits of supply. It complements and amends, if necessary applicable, the relevant IEC standards. For the purpose of this document the term "switchgear" is used for "gas-insulated metal enclosed switchgear". It does not cover directly immersed cable terminations, as described in CIGRE brochure 89 . [外文原描述]： IEC 62271-209:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62271-209:2019 covers the connection assembly of fluid-filled and extruded cables to gas-insulated metal enclosed switchgear (GIS), in single- or three-phase arrangements where the cable terminations are fluid-filled or dry-type and there is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) New numbering in accordance with ISO/IEC directives, Part 2 (2016) and to IEC 62271‑1:2017; b) Clause 3: addition of a definition for plug-in cable termination, filling pressure and minimum function pressure for insulation; c) Clause 7: An additional dielectric type test for plug-in cable termination was added; also a pressure type test as well as a leak rate test on the insulator of a cable termination was implemented; d) Clause 12: New clause about safety practices; e) Clause 13: New clause about influence of the product on the environment; f) New informative Annex A: Mechanical forces applied on the flange of the cable connection enclosure.
