摘要
介绍了矿用隔爆型真空馈电开关、矿用隔爆兼本质安全型真空电磁启动器等主要煤矿防爆电器的技术现状,提出一种以PLC为控制核心,集漏电、漏电闭锁、过载、断相、短路和欠压等故障保护于一体的智能保护器。
The technical status mine explosion-proof electrical apparatus of mine falme-proof type vacumm feed switch,mine falme-proof type with intrinsically safe vacuum electromagnetic stater are introduced,and design a kind of intelligent motor protector whice use PLC as control core and include many kinds of protection functions.
