高压开关设备和控制设备.第200部分:为使额定电压大于1 kV小于等于52 kV而采用的交流铁壳开关设备和控制设备

[中文适用范围]： 本部分 IEC 62271 规定了额定电压高于 1 kV 且等于或低于 52 kV 的交流预制金属封闭开关设备和控制设备的要求，适用于户内和户外安装，以及额定频率等于或低于 60 Hz 的场合。外壳可包含固定和可拆卸部件，并可填充流体（液体或气体）以提供绝缘。本标准定义了金属封闭开关设备和控制设备的几个类别，这些类别的区别在于：在维护开关设备和控制设备时对电网服务连续性的影响；以及对设备进行维护的必要性和便利性。 [外文原描述]： IEC 62271-200:2011 specifies requirements for prefabricated metal enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. This second edition cancels and replaces the first edition, published in 2003. It is a technical revision. This second edition of IEC 62271-200 has been further updated and improved to the experience gained with the first edition of IEC 62271-200. As maintenance result, this second edition of IEC 62271-200 introduces the following significant changes: - definitions, classifications and testing procedures are specified more precisely; - categories LSC2A and LSC2B have been clarified and LSC2 has been assigned a separate definition; - specific ratings related to fault level to earth (4.5 to 4.7) are introduced; - solid insulated high-voltage parts are no longer considered as compartments on their own; - an optional rating "cable test voltage" and the associated requirements and type tests are introduced; - for testing the internal arc classification, when assigned by the manufacturer, more specific guidance is provided regarding the test arrangement, room simulation and arc initiation; - a single phase to earth ignition is also recognised for internal arc testing; - the Annexes A and B are renumbered Annexes AA and BB. This publication is to be read in conjunction with IEC 62271-1:2007. The contents of the corrigendum of June 2015 have been included in this copy.
