摘要

目前偏磁式消弧线圈的研究是将励磁绕组电源简化为恒流源模型

得出消弧线圈的工作特性

但现场实践表明

消弧线圈实际工况中的偶次谐波电流分量已经大到不可以忽略

因此忽略偶次谐波电流而将励磁电流简化为恒流源在一定程度上影响了分析结果的准确度。针对此种研究方法的缺陷

考虑偶次谐波电流的实际影响

笔者提出了基于自由偶次谐波原理研究偏磁式消弧线圈工作特性的新方法

通过数学建模

得到了消弧线圈的调节特性和伏安特性。研究结果表明

基于自由偶次谐波原理的研究方法能够反映实际工况

并为偏磁式消弧线圈的优化设计提供了一个新的解决思路。

Abstract

In conventional research on arc-suppression coil with magnetic bias

exciting winding source is simplified as constant current source model to achieve the working characteristics of the arc-suppression coil.However

field practice indicates that even-order harmonic current induced by AC source is too large to be ignored

so the above simplification will reduce the accuracy of analysis results to a certain degree.Therefore

a novel method of research on characteristics of arc-suppression coil with magnetic bias based on free even-order harmonic principle is presented considering the influence of even-order harmonic current.Regulating characteristic and volt-ampere characteristic of arc-suppression coil are obtained through mathematical modeling.The results indicate that the proposed method can reflect actual situation

and play a new role in the optimization design of arc-suppression coil with magnetic bias.
