Routine maintenance of the elevator inverter


Application has been common drive fans, pumps, etc. to expand into the food, beverage, logistics, elevator drive internal structure building, and constantly open new energy field, and its function has also been improved and diversified, one is all-digital, fully functional, able to compensate for load changes adaptive, self-tuning technology, especially distributed communications, networking and integration of PLC-end elevator inverter; hand is simple or industry-specific mechatronic drive as well as small and medium of elevator inverter. In addition, new high-voltage power electronic devices because the advent of high and medium voltage elevator inverter also has made ​​great progress.
If they do maintenance work on the drive, you can greatly decrease the failure rate of the drive:
An elevator electrical room temperature is not too high, otherwise the drive components easy to aging, the best air-conditioned, the consequences quite good;
2, to prevent rain water, usually in a typhoon, the windows broken by the wind leaving the elevator inverter shower to rain;
3, lightning, this would relate to the whole building or all of the district mine facilities, so she was struck by lightning individual elevator inverter severe damage;
4, the drive's cooling fan to regularly dust cleared, the elevator inverter repair method using DC resistance line voltage detection and measurement are two methods and found that there was a noise or exchange will not run;
5, elevator motors unusual noise is usually drive problems, such as motor phase current is not balanced, then the best we must repair the damage is not complete until the elevator inverter may be more severe.
