In order to ensure the service life of the elevator inverter, the inverter manufacturer reminds us that the elevator inverter should be repaired and maintained regularly. In addition, the following issues should be paid attention to when repairing and maintaining the elevator inverter:
1. The cooling fan of the frequency converter should be cleaned regularly, and it should be replaced when it is found to be noisy or not working.
2. The abnormal noise of the elevator motor is usually caused by the problem of the inverter. If the three-phase current of the motor is unbalanced, it is better to repair it at this time. When the inverter is completely out of order, the damage may be more serious. If you have no maintenance experience, don’t repair it yourself to avoid making the inverter worse.
3. The temperature of the elevator electrical room should not be too high, otherwise the inverter components are easy to age, and it is better to be equipped with air conditioning, and the effect is quite good!
4. Prevent the rain from getting wet, usually when the typhoon blows, the windows and doors are damaged by the wind and the inverter is drenched with rain.
5. Lightning protection, this is related to the lightning protection facilities of the whole building or the whole community. The frequency converter struck by lightning is generally seriously damaged.
