标准摘要
[中文适用范围]: 准备此版本的主要目的是尽可能使文本和演示与 IEC 383-1 和 IEC 383-2 第四版保持一致。引入了支柱绝缘子的电气和机械等效概念, [外文原描述]: Applies to post insulators and post insulator units of ceramic material or glass for indoor and outdoor service in electrical installations or equipment operating on alternating current with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. Notes: -May also be regarded as a provisional standard for insulators for use on d.c. systems, see IEC 60438. -When considering hollow insulators, see IEC 60233. -Tests on indoor post insulators of organic material will be covered by a future publication: Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1 000 V up to but not including 300 kV. -For artificial pollution and radio-interference tests, see IEC 60437 and 60507. -For numerical values for insulator characteristics and for selection of insulators for specific operating conditions, see IEC 60273.
