本文分析了井下低压供电的现状及其对策。指出在“七·五”期间必须把低压供电主回路的研究放在重要的地位,努力提高其快速性、极限分断能力与电寿命,这将能减少电火花引爆瓦斯的危险,并为实现选择性的短路保护与漏电保护奠定基础。由于低压供电是一项复杂的系统工程,应重视新技术的综合开发与推广。本文对增设“短路器”实现快速断电技术方案也作了一定的分析探讨。
This paper analyzes the current situation and countermeasures of underground low voltage power supply. It is pointed out that during the “Seventh Five-Year Plan” period, the research on the main circuit of low-voltage power supply must be put in an important position to improve its rapidity, ultimate breaking capacity and electrical life, which will reduce the risk of spark gas explosion and realize the choice The basis of short circuit protection and leakage protection. As low-voltage power supply is a complex system engineering, should pay attention to the comprehensive development of new technologies and promotion. In this paper, additional “short circuit” technology to achieve rapid power outages have made some analysis and discussion.
