Abstract

The invention discloses an electric transmission system of a dual-power metro grinding car. The electric transmission system comprises a high-voltage electric appliance box, an electric reactor, a traction inverter, a traction motor, an auxiliary power generator, a three-phase rectifier cabinet, a grinding inverter and a grinding device, wherein power can be supplied to the traction motor and the grinding inverter through a contact grid, or power can be supplied to the traction motor and the grinding device through the auxiliary power generator. The invention further provides a power switching method for the dual-power metro grinding car. According to the method, seamless switching of the power supply between the contact grid and the auxiliary power generator can be realized. The electric transmission system has the advantages of being convenient to maintain, lower in energy consumption and pollution, and friendly to the environment; the power switching method has the advantages that the dual-power metro grinding car needs not to be shut down in the switching process, the flexibility and the convenience are guaranteed, the voltage is kept stable during the switching of the power supply, and the normal operation of the dual-power metro grinding car is not impacted.

Description

technical field [0001] The invention relates to the technical field of power transmission systems of rail transit construction machinery vehicles, in particular to an electric transmission system of a dual-power subway grinding vehicle and a power switching method. Background technique [0002] With the great development of urban rail transit in our country, higher requirements are put forward for the maintenance of subway lines. At present, domestic grinding vehicles use diesel generators + hydraulic transmission systems. Diesel generators provide driving power for grinding vehicles, and hydraulic transmission systems provide grinding power for grinding equipment. However, this transmission system has both electrical systems and There is a hydraulic piping system, the system is complex, and maintenance is inconvenient. There are electric transmission systems that simply use diesel generators as power sources abroad, but they use diesel generators to provide power, which wi...
