摘　　要：矿用防爆电器开关的前门与壳体的连接方式是影响其防爆性能的重要因素,其开启与闭合的快慢又直接影响矿工维修的方便性。文章以隔爆型电器开关的几种提升式开门结构为例,分析其优缺点,以及其各自适用的场合。The front door of the explosion - proof electric apparatus switch with the connecting way of the housing is an important factor that affects explosion - pro of performance. The speed of opening and closing also affects convenience of maintenance. Take several kinds of lifting door structure of explosion - proof electric apparatus switch as example to analyze its strong and weak points and its suitable situation.
