标准摘要
[中文适用范围]： 本国际电工标准 IEC 60168 适用于额定电压大于 1000 V 且频率不大于 100 Hz 的交流电气装置或设备中使用的室内和室外陶瓷或玻璃支柱绝缘子及支柱绝缘子组件。该标准也可视为用于直流系统支柱绝缘子的临时标准。IEC 60438 提供了这些绝缘子的一般指导。本标准不适用于复合绝缘子或属于其他 IEC 标准的室内有机材料支柱绝缘子。本标准的目的是定义：所用术语；支柱绝缘子的电气和机械特性；验证这些特性规定值的条件；试验方法；供货的验收准则。支柱绝缘子特性的数值在 IEC 60273 中规定。本标准不包括根据特定运行条件选择支柱绝缘子的要求。注 1：关于污染条件下绝缘子选择的指南已发布，见 [1]。注 2：本标准不包括无线电干扰试验或人工污秽试验。这些主题及相关试验方法在其他 IEC 出版物中处理，见 [2], [3] 和 [4]。注 3：当本标准应用于空心支柱绝缘子时，还应考虑其他 IEC 出版物，见 [5] 和 [6]。 [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. This consolidated version consists of the fourth edition (1994), its amendment 1 (1997) and its amendment 2 (2000). Therefore, no need to order amendments in addition to this publication.
英文名称Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal voltages greater than 1000 V
