空气断路器的长延时热脱扣试验台和试验方法

为了精确而迅速地考核空气断路器的热效应，对长延时脱热扣试验台和试验方法提出了较高的要求。作者多年从事交流稳流源的研究推广工作，对国内长延时热脱扣试验台现状比较了解，本文对长延时热脱扣试验台和试验方法及它们与稳流电源配合的情况作出一些探讨。

Test Table of Long Time Delay Heat Trip of Air Circuit Breaker and Test Method

In order to auccrately and speedy assess heat effect of air circuit breaker,the higher demands on long time deay tripping test table and test method are set.For many years author has heen engaged in study and spread work for AC current stabilized power source and has been in the know about the long time delay tripping test table at home status.The paper makes an approach to the long time delay heat trip test table and the test method and in coordination with current stabilized pawer source.
