摘　　要：针对继电器式本质安全先导电路存在自行启动和低电压启动不稳定的缺点,设计了一种新型的基于微机控制的光耦隔离式矿用磁力启动器本质安全先导电路,详细介绍了该电路的工作原理。实际应用表明,该本质安全先导电路性能可靠,运行稳定。In view of shortcoming that intrinsic safety pilot circuit controlled by relay exists unstable faults of self-starting and low-voltage starting, a new type of intrinsic safety pilot circuit with optical coupling isolation of mine-used magnetic starter based on microcomputer control was designed, working principle of the circuit was introduced in details. The practical application shows that the pilot circuit has reliable performance and stable operation.
