Specifically, the engine 10, the generator 20, and the rectifier 30 are provided in each of the first and second vehicles. Taking the first vehicle as an example, the engine 10 of the first vehicle can convert chemical energy of fuel oil into mechanical energy, the generator 20 of the first vehicle can convert mechanical energy into electrical energy, and the rectifier 30 of the first vehicle can convert alternating current output by the generator 20 of the first vehicle into direct current, so as to supply power to each inverter of the first vehicle.
The rectifier 30 of the first car is connected with the traction inverter 40 of the first car, the traction inverter 40 of the first car is connected with at least one traction motor 50, the traction inverter 40 of the first car can convert direct current output by the rectifier 30 of the first car into alternating current required by the traction motor 50, and the traction motor 50 of the first car can provide traction power when power is supplied.
The rectifier 30 of the first car is further connected with the grinding inverter 60 of the first car, the grinding inverter 60 of the first car is connected with at least one grinding motor 70, and the grinding inverter 60 of the first car can convert the direct current output by the rectifier 30 of the first car into the alternating current required by the grinding motor 70. Each grinding motor 70 is then connected to a predetermined number of grinding heads, which are not shown in the drawings of the present application.
The second vehicle section has the same principle as the first vehicle section, and the description is not repeated.
In practice, the number of traction motors 50 for both the first and second carts is typically 2. And considering that the grinding heads are disposed in both the first and second carts in the present application, the number of grinding motors 70 connected to the grinding inverter 60 in the first cart is the same as the number of grinding motors 70 connected to the grinding inverter 60 in the second cart in practical use. That is, the number of the grinding heads arranged in the first vehicle section and the second vehicle section is always consistent, and the balance of the working efficiency of the first vehicle section and the second vehicle section is ensured. Of course, the grinding head quantity of specifically arranging in first section car and the second section car can be set for and adjust according to actual need, for example in a concrete occasion, all set up 10 grinding motor 70 in first section car and the second section car, every grinding motor 70 all is connected with 1 bistrique, all set up 10 bistriques in first section car and the second section car promptly, this novel hybrid subway rail grinding wagon has 20 bistriques, work efficiency is higher.
In an embodiment of the present invention, referring to fig. 2, the method may further include:
a voltage reduction circuit 80 connected with the pantograph and used for receiving power supply of the power grid and reducing voltage, wherein the traction inverter 40 of the first car, the grinding inverter 60 of the first car, the traction inverter 40 of the second car and the grinding inverter 60 of the second car are all connected with the output of the voltage reduction circuit 80;

The voltage step-down circuit 80 may be generally disposed in the first bay or in the high-voltage cabinet of the second bay.
In this embodiment, the power supply by the pantograph is the default power supply method, that is, when the power supply by the pantograph is available, the first and second vehicles are supplied with the power by the pantograph, in consideration of the fact that the power supply by the fuel is heavy in pollution, and particularly, the noise pollution and the exhaust gas pollution are serious in the tunnel. Of course, when the pantograph cannot be used for power supply, for example, a power supply circuit of the pantograph is damaged, or a power grid is abnormal, the first vehicle and the second vehicle can both use fuel oil for power supply, so that normal operation is ensured, and the reliability of operation is improved.
