矿灯保护器过电流安全保护局限性的研究

Research on Limitations of Overcurrent Safety Protection of Miner's Lamp Protector

摘要: 矿灯保护器主要的作用是,当电源输出外电路发生过电流故障时,它能立刻切断故障电流,使电源得到安全保护,现行保护器在过电流故障保护中存在局限性。通过理论与实验分析,解析矿灯保护器在过电流保护中存在问题的实质和潜在的危险性,研究应对措施。

Abstract: The main function of miner's lamp protector is cutting off fault current immediately when a fault current happens in the power supply's external circuit in order to get power protected.The protector currently used has limitations in protection of current fault.This paper makes analysis of the essence of existing problems and potential risk in current protection of miner's lamp protector through the theoretical and experimental analysis,and the countermeasure was researched.
