摘　　要：工作面自动化是煤矿综合自动化系统发展的一个重要方向。为能驱动工作面自动化系统中相关的大功率电气设备,要求本安电源应具有较大的的输出电流。文章设计了一种基于LM723的矿用大电流输出本安电源,输出电压12V,最大限流1.4A,满足了工作面自动化系统相应的电气设备的供电要求。The automation of the coal mining face is an important direction of the mine comprehensive automation system development. In order to drive the large power electric equipment in the face automation system, the intrinsic safe power is required to have a high output current. The paper designed a mine intrinsic power with a high current output. The output voltage is 12V and the max current-limit is 1.4A, which could meet the power supply requirements of the related electric equipment in the face automation system.
