标准摘要
[中文适用范围]： 本技术报告适用于额定电压52kV以上高压空气绝缘隔离开关。该报告描述了电容电流开关负载，并提供了实验室测试指导以证明开关能力。配备辅助断路装置的空气绝缘隔离开关也属于本范围。注：对于手动操作隔离开关@，应考虑操作员的使用安全，并应认识到本文所述的开关测试结果（使用电动隔离开关进行）不一定代表此类隔离开关在使用中的性能。实际服务。如果开关测试表明电弧持续时间可能延长，则应进行尽职调查。 [外文原描述]： IEC/TR 62271-305:2009(E) applies to high-voltage air-insulated disconnectors for rated voltages above 52 kV. The report describes the capacitive current switching duty and provides guidance on laboratory testing to demonstrate the switching capability. Air-insulated disconnectors equipped with auxiliary interrupting devices are included under this scope. The contents of the corrigendum of June 2017 have been included in this copy.
