摘　　要：分布式电容随道岔控制距离变长而增加,电容堆积对道岔表示继电器正常工作造成极大影响,通过对分布式电容形成原因的理论探讨,得出影响分布式电容容值的因素,并提出工程应用中降低和解决分布式电容方法,对于提高交流道岔控制电路表示可靠性有积极意义。The distributed capacitance increases with the turnout control distance becoming longer, and the accumulation of capacitance has a great impact on the normal operation of turnout indication relay.Through the theoretical analysis of the causes of the formation of distributed capacitance, the factors affecting the distributed capacitance are obtained, and the methods to reduce and solve the distributed capacitance in engineering application are put forward. It has positive significance to improve the reliability of AC turnout control circuit.
