【摘要】 利用时域有限元方法分析了含不同应力控制管时的电缆终端电场分布。分析结果表明,采用由电容性和非线性电阻性材料复合绝缘结构的应力控制管时,电缆终端的电场分布最为均匀。进一步分析电缆终端中电容性和非线性电阻性材料知其分界面处含有气隙时的电场分布。更多还原

【Abstract】 A comparison of the electric field distribution in a cable termination with several difˉferent stress control tubes is presented.The result reveals that the stress control tube comˉprising a composite structure of the nonlinear resistive and capacitive material shows the best performance in improving electric field distributions in cable terminations.Further more,the distribution of electric field in cable termination is analyzed as cavities reside on the interface of a capacitive and a nonlinear resistive material.更多还原
