对标称电压大于 1 000 V 系统的陶瓷材料或玻璃的室内和室外支柱绝缘子进行测试

[中文适用范围]： 适用于标称电压大于 1 000 V、频率不大于 100 Hz 的电气装置或交流电设备中室内和室外使用的陶瓷材料或玻璃支柱绝缘子和支柱绝缘子单元。注： - 也可被视为直流系统中使用的绝缘子的临时标准，请参阅 IEC 438。 - 考虑空心绝缘子时，请参阅 IEC 233。 - 有机材料室内支柱绝缘子的测试将由未来的出版物涵盖：对标称电压大于 1 000 V 至 300 kV 系统的有机材料室内支柱绝缘子进行测试。 - 对于人工污染和无线电干扰测试，请参阅 IEC 437 和 507。 - 有关绝缘子特性的数值以及特定操作条件下绝缘子的选择，请参阅 IEC 273。 [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 438. - When considering hollow insulators, see IEC 233. - 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 437 and 507. - For numerical values for insulator characteristics and for selection of insulators for specific operating conditions, see IEC 273.
