摘要
基于后退欧拉法和变分原理推导了非线性的时域有限元电场计算方程。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。
Nonlinear electric field time-domain finite element equation is deduced based on the backward Euler method and the variation principle. A comparison of the electric field distribution in a cable termination with several different stress control tubes is presented. The conclusion shows that the electric field distribution in a cable termination equipped with a stress control tube comprising a capacitive and a nonlinear resistive material is the most uniform.
