Elevator inverter maintenance precautions

Frequency converters are widely used in life, such as fans, pumps, food, beverages, logistics, buildings, etc., and inverters are constantly developing, producing high-voltage inverters, medium-voltage inverters and low voltage. Inverter. For example, in the mall, we can often see the elevator, and the frequency converter plays an important role in the application of the elevator. If the inverter is used frequently, but does not pay attention to maintenance, it will cause safety hazards and will greatly reduce the efficiency of use. Therefore, in the process of elevator maintenance, you should pay attention to the following issues:

1, the elevator electrical room temperature can not be too high, otherwise the inverter components are easy to age, it is best to have air conditioning, the consequences are good!

2. Prevent rainwater from getting wet, usually when the typhoon is being blown, the window door is blown by the wind and the inverter is drenched into the rain.

3, lightning protection, this is related to the entire building or all residential lightning protection facilities, the lightning damage to the inverter is severely damaged.

4. The cooling fan of the inverter should be cleaned regularly. The maintenance mode of the inverter adopts two methods: online voltage detection and DC resistance measurement. It is found that it has to be audible or not to be replaced.

5, the elevator motor has abnormal sound is usually the inverter has problems, such as motor three-phase current is not balanced, then it is best to repair, until the inverter is not complete, the damage may be more severe.

The above content, the introduction of Xiaobian hopes to provide some help for everyone when repairing the inverter.
