摘要
针对邢台矿7717掘进工作面供电系统中存在的局部通风机双回路供电、备用局部通风机漏电保护、掘进机过流保护整定等问题,分析问题产生的原因,进行优化设计,提出解决方案。实践表明,优化设计很好的解决了现存的问题,为类似情况提供了经验借鉴。
Based on local ventilator double circuit power supply, alternate partial ventilator electrical leakage protection,mining machine overcurrent protection setting problems, the reason was analyzed, through the optimized design, the solving plan was put forward. The practice showed that the design could solve the problems and provide experience and reference for similar condition.
