摘要
针对煤矿井下易燃易爆的特殊环境,文中基于开关电源技术,设计了一种本质安全型LED驱动电源,能将输入输出隔离,并加入过压过流等保护功能,从而使故障时释放的能量符合国家本质安全标准的规定,提高煤矿井下用电设备的安全性及可靠性。
In view of the inflammable and explosive environment of coal mines, a design of intrinsically safe LED driver power supply based on the switching power supply technology is presented. It has the feature of electrical isolation with a variety of protection functions, such as over voltage protection, over current protection and so on, thus guaranteeing that, the energy released is in line with national standards of intrinsically safe should circuit fault occur. It can improve the security and reliability of coal mine.
