[0035] How it works

[0036] First, the fuel (diesel) enters each cylinder of the diesel engine, where combustion occurs. The heat energy generated by this process is converted into mechanical energy; the mechanical energy drives the engine crankshaft to rotate. This is achieved by the up and down reciprocating motion of the piston in the cylinder. This process includes four strokes: intake, compression, combustion and work (expansion), and exhaust;

[0037] The mechanical energy then drives an AC generator, which uses the principles of electromagnetic induction to convert mechanical energy into electrical energy. In an AC generator, the stator contains copper coils, while the rotor has coils wrapped around an iron core, which generate an electromagnetic field as the rotor rotates. As the magnetic field forms and weakens, the voltage fluctuates between positive and negative peaks, forming an AC electromagnetic field. In order to provide constant power, diesel generator sets are usually equipped with automatic voltage regulators (AVRs) or automatic magnetic field devices. These devices automatically adjust the magnetic field strength according to the power demand to ensure that the voltage level remains consistent;

[0038] The electricity generated by the generator can be connected to different loads through the selector switch. If the current exceeds the capacity, the circuit breaker will stop the system to protect the generator and connected equipment from damage. After the power reaches the connection panel, the operator can connect the power cord to the plug for daily use of the train air conditioner.

[0039] Optimize the overall layout of the power generation unit and place the diesel tank inside the unit. When the capacity is the same, it is different from the base tank and is far away from the diesel engine. It is not easily affected by the temperature of the diesel engine. The built-in diesel tank is safer to assemble, with lower cost, higher efficiency and lighter weight. The whole machine takes up less space when installed and is easy to maintain.

[0040] Adopting integrated design, compact structure, reducing the space occupied by the generator set;

[0041] The box adopts rainproof design, which can effectively prevent rain, snow and dust, improve efficiency and reduce production costs;

[0042] The weight is reduced and the material selection is high-strength; the equipment is easy to operate, safe and reliable, and easy to maintain; the appearance is simple and beautiful.

[0043] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
