石英砂熔断器开断过程的电弧数学模型

Mathematical Model for Arcing Process of Fuse

本文分析了熔断器短路故障电流的分断过程,并建立描述熔断器燃弧过程的电弧数学模型。用此模型对熔断器分断过程进行分析和计算,其结果和试验结果进行比较。

This paper analyses the interrupting process of fuse under short circuit. The mathematical model is set up which describes the arcing process of fuse, it is used to calculate the interrupting process of fuse, the calculation results agree with the test results.
