高压开关设备和控制设备.第209部分:额定电压大于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.充液电缆和干式电缆终端

[中文适用范围]： “IEC 62271 的这一部分涵盖了单相或三相布置中流体填充和挤压电缆与气体绝缘金属封闭开关设备 (GIS)@ 的连接组件，其中电缆终端为流体填充型或干式，并且有是电缆绝缘和开关设备气体绝缘之间的隔离绝缘屏障。本文件的目的是建立电缆终端和气体绝缘金属封闭开关设备之间的电气和机械互换性，并确定供电限值。补充和修订@（如果适用）相关的 IEC 标准。就本文件而言，术语“开关设备”用于“气体绝缘金属封闭开关设备”。它不包括所描述的直接浸入式电缆终端@见 CIGRE 手册 89 [4] 1。” [外文原描述]： 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.
