关于电气间隙和爬电距离的指南，特别是对于等于或小于 2 mm 的距离 影响参数研究的测试结果（第 1.0 版

[中文适用范围]： 本文件描述了对于印刷线路材料和其他等效绝缘布置@的间隙和爬电距离@尺寸等于或小于2毫米的研究的测试结果，其中间隙和爬电距离沿着沿着表面的相同路径。固体绝缘。本文件中包含的信息仅是研究结果，不能用于确定适用 IEC 60664-1 的低压系统@内设备的电气间隙和爬电距离。然而，出于功能原因，可以考虑距离。本文件提供了与以下标准相关的研究结果：1）独立于微环境的间隙； 2) 污染等级1@2和3的爬电距离，将更小的距离的使用扩展到具有与印刷电路板类似的设计特征的产品； 3）爬电距离以避免绝缘表面闪络； 4) 有关保持最小绝缘电阻的最小爬电距离的信息。描述了一种用于评估尚未分类的任何绝缘材料表面的相关吸水基团的测试方法。 [外文原描述]： IEC TR 63040:2016(E) describes test results of research on dimensioning of clearances and creepage distances, for spacing equal to or less than 2 mm for printed wiring material and other equivalent arrangements of insulation, where the clearance and the creepage distance follows the same path along the surface of solid insulation. The information contained in this document is the result of research only and cannot be used for dimensioning the clearances and creepage distances for equipment within low-voltage systems, where IEC 60664-1 applies. However distances can be taken into account for functional reasons. This document provides results of research related to the following criteria: 1) clearances independent from the micro-environment; 2) creepage distances for pollution degree 1, 2 and 3 which extends the use of smaller distances to products having design features similar to printed circuit boards; 3) creepage distances to avoid flashover of the insulating surface; 4) information on minimum creepage distances to maintain minimum insulation resistance. A test method for the evaluation of the relevant water adsorption group for the surface of any insulating material which has not yet been classified is described.
