    摘 要:以棱邊突出的金屬凸輪為研究對象,利用試驗及計算機軟件仿真分析其在高電壓下的放電現象及電場特性,分析邊沿效應及放電路徑等因素對放電過程的影響。通過施加冷縮增爬傘裙增加金屬導體之間的爬電距離,分析了冷縮傘裙與尼龍軸間界面壓力對沿面絕緣的影響,給出了冷縮傘裙選型方式。研究成果可用于各種電氣設備內部金屬導體尤其是不規(guī)則導體間的絕緣優(yōu)化設計。
    關鍵詞:金屬凸輪;冷縮增爬傘裙;爬電距離;界面壓力

    Abstract: Taking the rigid cams with protruding edges as the research object, this paper used the experiments and the computer software to simulate and analyze the discharge phenomena and electric field characteristics under high voltage, and analyzed the influence of edge effect and discharge path etc factors on the discharge process. By applying the cold shrink by climbing skirt to increase the creepage distance between the metal conductors, this paper analyzed the impact of the interfacial pressure between the cold umbrella skirt and the nylon shaft on the edge insulation and gave the selection method of cold shrink umbrella skirt. The research result could be used to optimize the insulation design of various interior metal conductors of electrical equipments, especially between the irregular conductors.
    Key words: metal cam; cold shrink by climbing skirt; creepage distance; interfacial pressure
