标准范围

IEC TS 61245:2015（E）适用于d.c.的确定。在室外使用和暴露于污染大气中的陶瓷和玻璃绝缘子的承受特性。系统最高电压大于+/-1 000 V的系统。这些测试不适用于聚合物绝缘体、涂油绝缘体或特殊类型的绝缘体（例如，带有半导体釉或覆盖有任何有机绝缘材料的绝缘体）。本技术规范的目的是规定适用于架空线路、变电站和牵引线路绝缘子以及套管的人工污染试验程序。这第二版取消并取代了1993年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)更正和添加解释材料；b)增加关于大气校正的第4.4.2条；c)绝缘子清洗用自来水体积电导率上限变化为0.1 S/m；d)延伸至UHV电压；和e)增加附件B“绝缘子耐受特性的测定”和附件E“+/-600 kV及以上电压系统绝缘子人工污染试验的补充信息（固体层法程序B）。

IEC TS 61245:2015(E) is applicable for the determination of the d.c. withstand characteristics of ceramic and glass insulators to be used outdoors and exposed to polluted atmospheres, on d.c. systems with the highest voltage of the system greater than +/- 1 000 V. These tests are not applicable to polymeric insulators, to greased insulators or to special types of insulators (e.g. insulators with semiconducting glaze or covered with any organic insulating material). The object of this technical specification is to prescribe procedures for artificial pollution tests applicable to insulators for overhead lines, substations and traction lines and to bushings. This second edition cancels and replaces the first edition published in 1993. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Corrections and the addition of explanatory material;
b) The addition of Clause 4.4.2 on atmospheric correction;
c) The change of upper limit of volume conductivity of tap water for insulator cleaning to 0,1 S/m;
d) The extension to UHV voltages; and
e) The addition of Annex B "Determination of the withstand characteristics of insulators" and Annex E "Supplementary information on artificial pollution tests on insulators for voltage systems of +/- 600 kV and above (solid layer method procedure B).
