摘要
针对煤矿地面供电系统的主要工作对象,提出了一种供电系统方案。首先分析煤矿供电系统的特性,研究了六大生产系统的供电需求与问题,其次针对存在的问题提出了一种供电系统方案,对一种电源快速切换装置进行了选型设计,可保证通风系统与排水系统的不间断工作,最后设计介绍了供电系统的保护方案,实现供电网络的继电保护功能。供电系统提高了容错率,当某一支路断电时,仍能保障矿井生产系统安全稳定的工作。
Aiming at the main working object of coal mine ground power supply system,a power supply system scheme is proposed.Firstly,the characteristics of power supply system in coal mine are analyzed,the demand and problems of power supply in six production systems are studied,then a power supply system scheme is put forward for the existing problems,and a power supply quick switching device is selected to ensure the uninterrupted work of ventilation system and drainage system.Finally,the protection scheme of power supply system is introduced to realize the relay protection function of power supply network.The power supply system improves the fault tolerance rate,and can still ensure the safe and stable work of the mine production system when a certain road is cut off.
