High voltage motor maintenance

High voltage motor maintenance relies on its own high-frequency vibration to generate vibration force. Therefore, during its working time, the motor itself will have a high temperature rise. It is precisely due to the existence of this matching gap that the shaft repaired by large high-voltage motor will expand after the temperature rise. The expanded shaft just fits closely with the bearing to achieve normal working state, If there is no gap of 0.01-0.0115mm, a series of problems will occur after the working temperature rise reaches a certain temperature, or even stop running or burn the high-voltage motor for maintenance. Therefore, attention should be paid to this problem in the maintenance of high-voltage motor.

High voltage motor maintenance is due to long-term continuous use, coupled with improper operation by users, motor faults often occur. Professional personnel should be responsible for high-voltage motor maintenance to ensure good motor operation. High voltage motor maintenance can save costs and improve motor utilization. The following is the purpose of hot pressing in the maintenance process of high voltage motor:

1. After setting, the thread can be embedded for convenience.

2. Coil curing can prevent moisture and water immersion.

3. Corona discharge beyond the notch.

4. Complete the sealing to the outside world and avoid high voltage breakdown.

Automatic control devices can be attached to the hot press, such as the constant temperature at which level H works, the constant temperature at which level F works, multiple hot pressing times, when to start and when to stand by for insulation. During hot pressing, you should buy some release agents, scavengers, residues and other tools from the designated manufacturers.
