低压配电系统短路电流和保护配合问题探讨

Discussion on Short Circuit Current Extremes and Protection Coordination of Low Voltage Distribution System

近些年来,我国的电力行业呈现出新的发展趋势,使得容易影响到低压配电系统稳定性的接地系统故障问题引起了广泛关注,亟待强化相关的技术措施。基于此发展背景,文中分析了低压配电系统常见的接地系统故障情况,深入探究了低压配电系统保护装置的要点,综合阐述了能够改善低压配电系统接地故障问题的技术手段,以期有助于防范电气事故。

In recent years,the electric power industry in our country has shown a new trend of development,making the fault of grounding system that easily affect the stability of the low voltage distribution system caused widespread concern,and it is urgent to strengthen the relevant technical measures.Based on the background of this development,this paper first analyzes the common grounding system failure in low voltage distribution system,and then based on the key points of the protection device of low voltage distribution system,and finally unify the contents of the argumentation,and comprehensively elaborate the technical means to improve the problem of grounding fault in the low voltage distribution system,in order to help prevent it.Electrical accidents.
