摘要
高压本安电源在煤矿电缆故障诊断中起着至关重要的作用,传统的本安电源限流电路在使用中存在着缺陷;介绍了一种用于高压本安电源的新型过流保护电路,详细分析该电路的工作原理,并与传统方法进行了详细比较,通过试验验证本电路的保护功能优于传统方式,且该电路简单可靠,调试方便,为高压本安电源的设计提供了条件。
High voltage intrinsic safety power source plays a vital role in coal mine cable fault diagnosis,but there are defects in using the traditional intrinsic safety power limiting circuit. We introduce a new type of overcurrent protection circuit for high- voltage intrinsic safety power source,analyze the working principle of the circuit,and compare with the traditional methods. The circuit has a better protection than traditional methods validated in actual application,and the circuit is simple,reliable,easy to debug,which provides condition for the design of the high voltage intrinsic safety power source.
