Description

Generator output control device of engine locomotive

This creation relates to a generator output control device with an engine locomotive, mainly referring to a device that can control whether the engine drives the generator output.

At present, locomotives with engines generally have multiple electrical equipment such as generators, batteries, starting motors, lights, horns, etc. The power output by the generators and batteries can be used by various electrical devices, and the generators are generally permanent magnet AC The generator has a stator and a rotor driven by the engine crankshaft, and the magnetic field generated when the engine rotates the rotor can be cut by the stator and generate an induced current, and the output AC power is rectified and stabilized by the rectifier circuit and then output to various electrical equipment, and The battery can be charged, and when the output of the generator has fully charged the battery and exceeds the demand of the electrical equipment, it will be consumed by a short circuit to stabilize the voltage and avoid battery overcharging and damage to the electrical equipment.

Therefore, the current locomotive electrical system is designed to generate a magnetic induction output current when the locomotive engine is activated. However, the reluctance generated by the generator will increase the engine load.

As shown in FIG. 6, it is a starting circuit of a conventional engine, which mainly has an electric door lock SW1, a start button switch SW2, a start relay Relay1, and a starter motor M. The electric door lock SW1 and the start relay Relay1 are connected to the battery power supply B ⁺ , When the electric door lock SW1 and the start button switch SW2 are turned on at the same time, the start relay Relay1 can be activated, and the battery power B ⁺ can be output to the start motor M to start the engine.

However, the engine must be synchronized to drive the generator to generate electricity, causing the battery to have a large output to start the engine. In practice, when the vehicle is cold or the battery is aging, it often happens that repeatedly pressing the start button switch SW2 still fails to start the engine, causing the final locomotive battery to run out. However, when the engine cannot be started, the engine must be driven to generate electricity synchronously, which causes the engine to maintain the load of the generator while driving and reduce the speed of the vehicle.

The purpose of this creation is to provide a device that can control whether the engine drives the complete output of the generator.

The control device of this creation is electrically connected between the output end of the locomotive generator and the battery input end, and can control the normal output current of the locomotive generator output end to the locomotive battery when the engine is operating or the output end has no output current to the battery .

Further, the locomotive generator output terminal is electrically connected with a brake fluid such as SCR that can be controlled to conduct or not; the switch actuator is electrically connected to the brake fluid, and when the switch actuator is activated, the brake fluid can be activated Cut-off or conduction operation.

Further, the control device has at least one relay, and the contact of the relay is switched by the action of the switch actuator, and the generator output or non-output action.

Further, the control device further includes an engine start detection device, the engine start detection device receives the detection information of the engine start operation, and can sense that after the engine is started, the switch actuator is converted into an operation only for the output of the generator. .

This creation can reduce the load on the engine by making the switch actuator control the engine output when the engine is in motion, which can reduce the engine load and facilitate engine start. Improve the speed effect.

The switch actuator of this creation can be shared as one of the original locomotive switches. For example, when the start button switch can be used, the control device further includes an engine start detection device. The engine start detection device is electrically connected to the locomotive engine start circuit, and Receives the detection information that the engine is started and delays the set time, and can sense that the engine is started for a set time, and then the start circuit and the start button switch are disconnected, and the start button switch can be controlled to increase the vehicle speed at an appropriate time without starting the locomotive. motor.
