摘要
本文对气吹电弧电流零后的介质热恢复特性进行了研究.在积分法原有的基础上发展了电流零后积分方程的数值解法。对 BBC 喷口和 GE 喷口气吹电弧进行了求解.在一定的范围内,数值计算结果能较好地吻合实验数值,为预测气吹电弧的热开断特性提供了有效的计算方法.
The thermal dielectric recovery characteristics of gas blast arcs after current
zero are investigated,Computational programs based on the integral method are
developed to study the dynamic behaviour during ourrent zero period.BBC and
GE nozzle arcs are solved.The agreement between calculation and experiment
results is acceptable.So an effective calculating method for predicting the ther-
mal interruption capability of gas blast ares is obtained.
