Abstract

The utility model discloses a main transmission system circuit structure suitable for a double-source subway project maintenance vehicle. Two common current sensors replace a differential current sensor in an existing circuit structure. The two current sensors can respectively detect main circuit input end currents and backflow currents, and the difference between the main circuit input end currents and the backflow currents is a main circuit leakage current. Due to the fact that the price of the common current sensors is much lower than the differential current sensor, cost is reduced.
