摘要

基于叠加原理和对称分量法

文章推导出一种供计算三相对称网络中电流开断后恢复电压用的拉氏阻抗网络图

文中还给出了这一方法的几个应用的例子

对三相接地和不接地短路开断的首相开断系数的计算结果表明

在实际电网中这些系数比高压交流断路器的相应标准中所规定的要小。

Abstract

Based on the superposition theorem and the symmetrical compoent method

the connection diagrams of Laplace transformation impedance for calculation of recovery voltages in three-phase symmetrical networks are deduced and some application examples by this method also presented in this paper. The calculated results of the first-pole-to-clear factors for three-phase earthed and unearthed short-circuit current interruption show that the factors in the actual networks are lower than that specified in the corresponding standards for high-voltage alternating circuit breakers.
