摘要
为解决目前矿用本安电源上电时,因负载电容充电造成本安电源误动、可靠性差的现状,结合本安电源短路保护的整定原理和本安电源的特点,对决定本安电源性能和设计水平的核心电路(可靠性组件电路)进行研究,提出一种新型本安电源的设计方案。在该方案中采用功率监视IC做可靠性组件的核心芯片,减小取样电阻值,实现过流、过压、过功率保护,增加上电保护电路,解决了容性负载上电时对本安电源暂态冲击的影响。结果表明,该设计方案提高了本安电源的带负载能力和可靠性。
In order to solve the present mine intrinsic safe power connected on power,due to the wrong action of the intrinsic power oc- curred by the loaded resistance charging charge and the poor reliability,in combined with the setting principle intrinsic safe of the power short circuit protection and the power features,the paper studied the key circuit reliability module circuit to the intrinsic safe power per- formance and design level.The paper provided new design plan of the mine intrinsic safe power.The design...
