How to do the common faults and elimination of electrical control system in Guiyang elevator company
1. From the scope of the electrical fault of the elevator, the most common is the malfunction of the door machine system and the poor contact of electrical components. There are many reasons for the malfunction of the door and electrical components, such as the quality of the components, the quality of the installation and debugging, the quality of maintenance and so on.
2. From the nature of electrical faults, there are two kinds of short circuits and circuit breakers.
The short circuit is due to some reason, it is the connection or connection of the circuit that should not be connected and the resistance in the line is very small. The common causes of short circuit faults in elevators include mechanical and electronic linkage failures of a directional contactor or relay.
May have robbed the contactor or relay action caused by short circuit; the main contact of the contactor is switched on or off, the arc to medium electrical components around the dielectric breakdown and short circuit; insulation aging and failure, caused by damp short-circuit electrical components; due to insulation failure and foreign material intrusion cause of electrical components caused by the outside world short circuit.
