摘　　要：介绍了一种矿用道岔控制器的按钮电路,通过对现有按钮控制方式的隐患分析与电路改进设计,阐述了其存在隐患的设计对策。通过对按钮线路绝缘阻抗特性分析,结合线路绝缘检测技术,设计实现了具有绝缘检测功能的按钮线路漏电监督电路,解决了因按钮线路漏电引起的误动作驱动,从而实现了道岔控制器的安全可靠工作。This paper introduces the button circuit of a mining switch controller. Through the analysis of the existing hidden trouble of button controls, and improved design of circuit, expounds the design countermeasures of the existence of the hidden dangers. The characteristic impedance of the button line insulation analysis, combined with the line insulation detection technology, design and implement with button line leakage supervision circuit insulation detection function, to solve the misoperation switch control caused by button line leakage, in order to achieve a safe and reliable switch controller.
