摘要

传感器绝缘子被广泛用于中压开关设备中既起绝缘支撑作用也作为取电压信号的传感器。其绝缘水平直接影响开关设备整体绝缘性能。现场运行与试验结果发现

内部传感器与外部伞裙的设计严重地影响了外伞裙表面的电场分布。文中通过对5种不同绝缘结构的传感器绝缘子的爬电距离与其工频耐压水平的关系进行电场分析及极限工频耐压试验

详细分析了不同爬电距离与对应的极限工频耐压水平之间的联系

为同类产品的结构设计与仿真分析提供参考。

Abstract

The sensor insulators are used as support and to achieving voltage signal in medium voltage switchgears

and its insulation level directly determines the insulation performance of the entire set of equipment. Field operation and test results show that sensors embedded in epoxy resin and shed structure heavily affect on the distribution of electrical field on the surface of insulator. By comparing

analyzing and discussing the relationship between creepage distance and power frequency withstand voltage level of sensor insulators of 5 different insulation structures

the relationship between creepage distance and power frequency withstand voltage level is obtained. These results can provide usable reference for the structural design of similar products and electrical field simulation.
