摘　　要：通过一系列雷电与操作冲击试验,研究了底架高度与支柱绝缘子冲击电压耐受强度之间的关系。其中对金属底架、试验回路、试品布置以及试验方法进行了描述,然后通过仿真模型计算分析了空间电场强度分布,并从试验结果和仿真分析中总结出了金属底架高度与支柱绝缘子50%放电电压之间的规律,并得出绝缘子最短放电距离与底架高度近似相等时,技术与经济效果较好。The relationship between height of metal chassis and impulse voltage withstands intensity of post insulator are studied a series of switch and lightning impulse voltage tests. The detailed description of metal chassis, test object installation, test circuit and test method are given. Then the distribution of electric field intensity is calculated and analyzed based on simulation model. Finally the relationship between the height of metal chassis and the post insulator 50% discharge voltage is obtained by the test results and simulation analysis, and it is also obtained that the technical and economic effect is better when the minimum discharge distance of the insulator is approximately equal to the height of chassis.
