关于高压开关设备相间爬电比距应用系数数值的探讨

Disscussion about Applied Value of Specific Distance of Creepage Between Phases in High Voltage Switch Equipment

现行的有关行业标准规定了高压开关设备外绝缘公称爬电比距应用系数,其中相间爬电比距应用系数为3√。作者就这一数值的合理性进行了引证和论述,提出了自己的观点。

In the related profession standard,the nominal insulated applied Value of specifil creepage out high voltage switch equipment is provided,and the value between phases is3√.In this article the reasons about the value are cited and discussed,and its own opinions are put forward.
