摘要
严格按照本安电路的设计原则及方法,本文介绍了一种矿用本质安全型电源,该电源可用于含爆炸气体和粉尘的煤矿井下,拥有两级过流保护一级过压保护,它的输入为127VAC,输出为2路5VDC,重点介绍了过流保护和过压保护的详细设计,并测试了它的机械性能和电气性能,结果表明该设备通过了国家各项指标,在煤矿的实际应用中取得了良好的效果。
This article introduces a kind of essentially electricity power source of exploiting mineral according to the designing principles and measures of Aberdeen circuit strictly. This electricity power source can be used to coal mine which is under the well and contains explosiveness gas and dust. Besides, this electricity power source owns two level over current protection and a-level overvoltage protection which input is 127VAC and output is 5VDC of 2 current. This article mainly talks about detail design of overcurrent protection and overvoltage protection, and tests its mechanical function and electricity power source passed of item indexes in China and gained well effect in the practical apolication.
