直流系统中直流电弧的研究与实践

Research and Practice of DC Arc in DC System

直流配电过程中直流负荷或相关电气开关开断时可能存在燃弧问题。本文旨在探索直流电弧相关知识,研究直流电弧的产生原因和特性,探讨不同负载特性条件下直流电弧的起弧情况,并给出实际实验结果,为后续应对低压直流配电系统中的电弧问题提供参考。

There may be arc-pulling problems when DC load or related electrical switches are interrupted in DC distribution process.The purpose of this paper was to explore relevant knowledge of DC arc,to study the causes and characteristics of DC arc,to explore the arc-starting situation of DC arc under different load characteristics,and to give the actual experimental results for subsequent response.The arc problem in low voltage DC distribution system can be referred to this article.
