Routine maintenance of elevator inverter


Application has been common elevator inverter fans, pumps, etc. to expand to the food, beverage, logistics, building, and constantly open new energy field, and its function has also been improved and diversified, one is fully digital, fully functional, able compensate for load changes adaptive, self-tuning technology, especially distributed communications, networking and integration of PLC-end elevator inverter; hand is a simple elevator inverter or industry-specific as well as mechanical and electrical integration, miniaturization lift inverter. In addition, new high-voltage power electronic devices because the advent of high-voltage and medium-voltage drive elevators also have made ​​great progress.
If you usually carry out maintenance on the elevator inverter, you can greatly decrease the failure rate of elevator inverter:
An elevator electrical room temperature is not too high, otherwise elevator inverter components easy to aging, preferably 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 elevator inverter individual damage grim;
4, elevator inverter cooling fan to regularly clean the dust, elevator inverter repair method using DC resistance line voltage detection and measurement of both methods and found that there was a noise or exchange will not run;
5, elevator motors unusual noise is usually elevator inverter problems, such as motor phase current is not balanced, then the best will repair, it is not complete until the elevator inverter may be more severe damage.
