摘　　要：根据煤矿井下常用的隔爆兼本安电源的功能要求,参照Exib I本安防爆的基本标准、本安电源的工作原理和系统构成的基本要求,利用浪涌抑制器芯片LT4356作为过压过流保护器件,采用双重过压过流保护电路,设计了一种具有自动恢复功能、欠压馈电检测功能、电源输出为双路18V/1A的本安电源。在实际使用中,它具有输出可靠、带负载能力强、体积小、装配调试简单、安装方便等优点。According to the characteristics of proof and intrinsically safe power supply commonly used vibration of coal mine, intro- duces the basic requirements of ExibI explosion-proof and intrinsically safe power supply of the working principle, system structure and circuit design. The use of power surge suppressor chip LT4356 as the overvoltage and overcurrent protection device adopts dou- ble over-voltage and over-current protection circuit, and has the automatic recovery, undervohage feed detection function, the out- put of the power supply for the dual 18 V and 1 A. In actual use, it has a reliable output and load capacity, small volume, sim- ple assembly and debugging, simple installation etc.
