摘要

断路器在按额定操作顺序进行短路开断试验时

其燃弧时间应覆盖最短、中间和最长3种时长

对于某些断路器

需要采取延长电弧燃烧时间的措施

以进行长燃弧时间甚至中燃弧时间的试验。文中针对脉冲电流延弧回路的参数进行了计算

给出了延弧回路参数的计算式

并对其运行条件进行了分析

叙述了克服这些问题的方法

提出了建议的延弧支路接线以及可能结构形式。

Abstract

In the short circuit breaking test of circuit breakers in accordance with rated operation sequence

its arcing time shall cover such three intervals as the minimum

medium and maximum arcing times. For certain circuit breaker

the measures of prolonging arcing time shall be taken to perform the test at maximum and even medium arcing time. In this paper

the parameters of prolonging arc circuit of impulse current are calculated and the calculation formula of the prolonging arc circuit are given. Its operation conditions are analyzed and the method on how to overcome above problems are described. The wiring and possible structure form of the suggested prolonging arc branch are proposed.
