The most significant factor of passenger elevator failure is the failure of the electrical control system. There are many reasons for the failure of electrical control systems. The main reason is that the quality and maintenance of electrical components are unqualified. Bed Elevator Supplier introduced that electrical system failures can be roughly divided into two categories:
1.An open-circuit fault occurred in the electrical circuit. In the circuit, it is often found that the crimping screws of the incoming and outgoing wires of the electrical components are loose or the solder joints are weakly welded, which causes the electrical circuit to open or make poor contact. When the circuit is broken, check and repair must be carried out immediately; poor contact may cause people or lead wires to draw an arc and burn out the contacts and electrical components over time.
2. Short circuit failure. When a short-circuit fault occurs in the circuit, the fuse will be burnt in the slightest, and the electrical components will be burned in the worst, and it may even cause a fire. Common mechanical and electrical interlock failures with contactors or relays may cause contactors or relays to snap and cause short circuits. When the main contact of the contactor is turned on or off, the arc generated causes the surrounding medium to break down and cause a short circuit. The aging, failure, and dampness of the insulation materials of electrical components can also cause short circuits.
