Abstract
The utility model provides an AC380V power system traction motor cooling fan which comprises a machine shell assembly, an AC380V motor, an impeller and an air inlet. The AC380V motor is fixedly arranged on the machine shell assembly and located on one side of the machine shell assembly, the AC380V motor is connected with the impeller, the impeller is arranged in the machine shell assembly, and the air inlet is fixedly formed in the machine shell assembly and located in the other side opposite to the AC380V motor. The AC380V power system traction motor cooling fan has the advantages that the voltage of a rated power supply is matched with that of the power supply of a high speed train circuit, the situation that due to the fact that the voltage of the power supply is reduced, the rotating speed of the fan is lowered, and the temperature of the motor rises too much can be prevented, and the long-term safe and reliable operation of the motor can be met.
Description
Technical field
The utility model relates to EMU traction electric machine cooling blower, particularly a kind of traction electric machine cooling blower that can long-time running under the AC380V power supply.
Background technique
Current conventional EMU traction electric machine AC400V during with the use voltage of cooling blower, if long-time running under the AC380V power supply, can cause blower-use motor input voltage too low, current of electric is increased, cause that electric machine temperature rise raises, shorten motor working life, affect rail motor set safety, reliable operation.
Summary of the invention
In order to overcome the above problems, the utility model provide a kind of do not affect gas fan working life, can long-term normal operation under the AC380V power supply the traction electric machine cooling blower.
AC380V power supply standard traction electric machine cooling blower described in the utility model comprises: casing composition, AC380V motor, impeller, intake grill, wherein the AC380V motor is fixed on the side that the casing composition was gone up and be positioned to the casing composition, the AC380V motor is connected with impeller, impeller is positioned at casing and forms, intake grill is fixed on casing and forms above, is positioned at the opposite side opposite with the AC380V motor.
A kind of AC380V power supply of the utility model standard traction electric machine cooling blower, its rated power supply and EMU line power voltage are complementary, and can prevent from causing rotation speed of fan to reduce because supply voltage descends, electric machine temperature rise is too high, and can meet motor long-term safety reliable operation.
In order to reach better effect, AC380V power supply standard traction electric machine cooling blower described in the utility model can also adopt following measures:
1, the utility model also comprises a guard, is fixed on casing and forms above, and it is positioned at the intake grill outside.Its role is to dust shielding outside blower fan, make the interior air-flow of blower fan purer, avoid damage equipment.
2, casing described in the utility model forms the top that is positioned at AC380V motor one side the motor pad is set, and the AC380V motor is fixed on casing by this motor pad and forms.
3, on AC380V motor described in the utility model, air plug also is set, is connected with the AC380V motor by cable.
