About the daily maintenance of the elevator inverter: Now the elevator is controlled by the inverter. When the inverter fails, it will cause inconvenience to many people, and it will also irritate the management personnel. If the inverter is usually maintained, Greatly reduce the failure rate of the inverter. After repairing a large number of elevator inverters, we have summarized several problems that should be paid attention to during normal maintenance:
1) The temperature of the elevator electrical room can't be too high, otherwise the inverter components are easy to age, it is better to have air conditioning, the effect is quite 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 lightning protection facilities of the whole building or the whole community. The inverters that are struck by lightning are generally damaged seriously.

4) The cooling fan of the inverter should be cleaned regularly, and it should be replaced if it is loud or not running.

5) The abnormal sound of the elevator motor is usually caused by the inverter. If the three-phase current of the motor is unbalanced, it is best to repair it. If the inverter is completely out of order, the damage may be serious. If you don't have maintenance experience, don't repair it yourself. Many people make the inverter worse.
