Device and method for fault detection of motor cooling system

Abstract

The invention discloses a motor cooling system fault detection device and method. The motor cooling system fault detection device comprises a first box body, wherein a switch is arranged on one side of the first box body, a storage battery electrically connected with the switch is arranged on the rear side of the first box body, and the first box body is internally provided with a small air pump,a winding mechanism, an air pipe and air flow meters. The motor cooling system fault detection method is characterized in that air is conveyed into a cooling pipeline of a driving motor cooling mechanism through the small air pump, and meanwhile, whether the blockage problem exists in the cooling pipeline of a driving motor can be measured according to the flow difference between the two flow meters, so that vacancy of the aspect in the market at present is solved, and whether the cooling pipeline of the driving motor is blocked or not can be rapidly detected, and the convenience is provided for fault detection; and the device is novel in design, simple in structure, convenient to use and particularly suitable for detecting faults of a cooling structure of a driving motor of an electric bus.

Description

technical field [0001] The invention relates to the technical field of motor cooling structure fault detection, in particular to a motor cooling system fault detection device and method. Background technique [0002] At present, in order to protect the living environment of human beings and save non-renewable resources, the energy consumption structure must be changed to avoid the energy crisis. Therefore, new energy vehicles play an important role in the current situation, and the drive motor is the heart of electric vehicles. Due to its small size and high power density, the driving motor will generate a lot of heat when it is working, resulting in a high temperature rise of the motor, accelerating the aging of the insulation, and affecting the safe and stable operation of the motor. Therefore, the heat dissipation of the driving motor is in the electric motor. It is especially important in the car. Most of the driving motors are heated by water-cooled fans, and the cooli...

[0002] At present, in order to protect the living environment of human beings and save non-renewable resources, the energy consumption structure must be changed to avoid the energy crisis. Therefore, new energy vehicles play an important role in the current situation, and the drive motor is the heart of electric vehicles. Due to its small size and high power density, the driving motor will generate a lot of heat when it is working, resulting in a high temperature rise of the motor, accelerating the aging of the insulation, and affecting the safe and stable operation of the motor. Therefore, the heat dissipation of the driving motor is in the electric motor. Especially important in cars

Most of the driving motors are heated by water-cooled fans, and the cooling pipes are prone to blockage. Once blocked, the cooling effect will be reduced. At present, there is no special inspection device for cooling faults on the market, so it is impossible to determine whether the pipes are blocked, which increases the difficulty of detection.
