Research on Fault Treatment and Circuit Analysis of Five-Wire Turnout

Turnout is an important signal equipment in rail transit. Its stable and safe work can directly ensure the safety of train operation. The five-line turnout is one of the most frequently used types, and its fault detection is particularly vital for rail transit operation. This research mainly analyzes the working principle and enabling path of five-wire turnout control circuit, action circuit and indication circuit are mainly analyzed. The malfunction existing in the turnout indicating circuit is determined by a combination of graphics and images. Measure and compare the voltage data during normal operation and line break and short circuit fault. The variation rule of voltage data is summarized when the circuit is broken or short inside and outside, and the fault point of the circuit equipment is quickly located. To achieve the purpose of quick troubleshooting and ensuring driving safety.
