电力机车辅助电机主要是为了保证主电路的正常工作而设计的辅助设备，其是否

Auxiliary motor electric locomotive primarily to ensure the normal operation of the main circuit designed auxiliary equipment, depending on whether it is to work the working status of the main circuit, even if the ambient temperature is low, although the main circuit in traction or braking working conditions, but the temperature rise of the main circuit electrical equipment of these auxiliary equipment and services is not high, this is not only a waste of energy, increasing the loss of equipment, reducing its service life, but also have a great mechanical and electromagnetic noise, affecting crew comfort workers work becomes. Auxiliary motor is an important equipment from auxiliary power circuit, comprising an asynchronous splitter, an air compressor motor, blower motor traction, braking fan motors, fan motors and transformers submersible pump motors. <br>For electric locomotive auxiliary motor control, first of all should be clear control target, analyze their characteristics and control requirements, the control strategy, control system design program to determine the specific implementation approach. The total pressure of the air compressor air cylinder is controlled by the pressure controller, the brake resistor fan is controlled by the driver braking conditions, the control thereof is not changed. Traction fan, fan control transformer of the driver manual control, this paper SS4G electric locomotive auxiliary motor as the object of study, focused on the auxiliary motor failure occurred in the operation and handling.

Electric locomotive auxiliary motor is mainly designed to ensure the normal operation of the main circuit auxiliary equipment, whether it is put into operation depends on the operating state of the main circuit, even in the case of low ambient temperature, although the main circuit works in traction or braking conditions, but these auxiliary equipment service main circuit electrical equipment temperature rise is not high, This not only causes energy waste, increases the loss of equipment, reduces its service life, but also produces a lot of mechanical and electromagnetic noise, affecting the comfort of the work of flight attendants. Auxiliary motor is an important equipment of electric locomotive auxiliary circuit, which includes asynchronous split camera, air compressor motor, traction ventilator motor, brake ventilator motor, transformer fan motor and submersible pump motor. <br>For the electric locomotive auxiliary motor control, first of all, we should clearly control the object, analyze their characteristics and control requirements, study the control strategy, design the control system scheme, determine the specific way to achieve. The air compressor is controlled by the pressure controller according to the pressure of the total cylinder, and the brake ventilator is controlled by the driver when the resistance brakes are operating, and the way they are controlled is not changed. The control of traction ventilator and transformer ventilator is the driver's manual control, and this paper focuses on the fault and treatment of the auxiliary motor in operation with ss4G electric locomotive auxiliary motor as the research object.

The auxiliary motor of electric locomotive is mainly the auxiliary equipment designed to ensure the normal operation of the main circuit. Whether it is put into operation depends on the working state of the main circuit. Even if the ambient temperature is very low, even though the main circuit works in traction or braking conditions, the temperature rise of the main circuit electrical equipment served by these auxiliary equipment is not high, which not only causes energy waste and increases The loss of equipment is added to reduce its service life, and at the same time, it also produces a lot of mechanical and electromagnetic noise, which affects the comfort of crew. Auxiliary motor is an important equipment of electric locomotive auxiliary circuit, which includes asynchronous split camera, air compressor motor, traction fan motor, brake fan motor, transformer fan motor and submersible pump motor.<br>For the auxiliary motor control of electric locomotive, first of all, it is necessary to define the control object, analyze their characteristics and control requirements, study the control strategy, design the control system scheme, and determine the specific implementation path. The air compressor is controlled by the pressure controller according to the pressure of the main air cylinder, and the braking ventilator is controlled by the driver under the resistance braking condition, and their control mode does not change. The control of traction fan and transformer fan is controlled by the driver manually. In this paper, the auxiliary motor of SS4G electric locomotive is taken as the research object, and the faults and treatment of the auxiliary motor in operation are discussed.<br>
