摘要

为探究熔断器燃弧过程中电弧压力的变化，文中首先设计了一种熔断器内部压力检测方法，可通过外置支架和压力传感器的配合达到测量内部压力的目的。其次，通过两组对比试验验证了测压方式的准确性和可行性，该测压方法可用于对电弧压力和燃弧过程关系的深入研究。再次，设计4组相同电路参数、不同起弧电流的分断试验，以此模拟不同电弧压力的分断试验，记录试验参数、拟合电弧电导率，分阶段对燃弧过程进行了分析。结果表明，各组试验间电弧压力与燃弧功率呈明显映射关系，电弧压力在各个燃弧阶段中对燃弧过程影响不同，在相同电弧功率密度下，电弧电导率与电弧压力存在比例关系。

Abstract

For exploring the variation of arc pressure durign the arcign process of fuse

a internal pressure detection method for fuse is firstly designed and the internal pressure measurement can be achieved through the coordination of external bracket and pressure sensor. Then

the accuracy and feasibility of the pressure measurement method are verified by two groups of comparative tests. This pressure measurement method can be used to deeply study the relationship between arc pressure and arcing process. After that

four sets of breaking tests with same circuit parameters but different arc ignition currents are designed to simulate the breaking tests with different arc pressures

record the test parameters

fit the arc conductivity

and analyze the arcing process by stages. The results show that there is an obvious mapping relationship between the arc pressure and the arcing power in each test set

and the arc pressure has different effects on the arcing process in each arcing stage. Under the same arc power density

the arc conductivity exhibits propotional relationship the arc pressure.
