Research on Electronic Switch in Ground Automatic Passing Phase System

Abstract

This article mainly designs a new type of ground automatic phase separation device. The electronic switch with thyristor as the component is used to replace the traditional vacuum switch to switch the two-phase voltage when the locomotive passes through the phase separation zone. The conversion time of the two-phase voltage is controlled from 10ms to 40ms by the new ground automatic phase passing device, which is a great improvement compared with the traditional mechanical switch of 300ms. It is verified through simulation experiments that the locomotive conversion time is reasonably shortened, and the overvoltage and impact are reduced when the electronic switch is closed and opened. The rationality and feasibility of the electronic switch are verified.
