绝缘子表面疏水性的测量指南

[中文适用范围]： 本技术规范所述的方法可用于架空线路、变电站及设备用复合绝缘子伞裙和外壳材料或包覆或不包覆涂层的陶瓷绝缘子疏水性的测定。获得的值代表测量时的疏水性。本技术说明书的目的是描述可用于确定绝缘体疏水性的三种方法。水润湿绝缘子表面能力的测定可能有助于评估使用中绝缘子表面的状况，或作为实验室绝缘子测试的一部分。 [外文原描述]： IEC TS 62073:2016(E) specifies the measurement of the hydrophobicity of the shed and housing material of composite insulators for overhead lines, substations and equipment or ceramic insulators covered or not covered by a coating. The obtained value represents the hydrophobicity at the time of the measurement. The object of this technical specification is to describe three methods that can be used to determine the hydrophobicity of insulators. The determination of the ability of water to wet the surface of insulators may be useful to evaluate the condition of the surface of insulators in service, or as part of the insulator testing in the laboratory. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Changed wettability to hydrophobicity throughout the document b) Redefined the criteria for the determination of hydrophobicity class in paragraph 3.4.
