MAIN DRIVE CONTROL METHOD FOR GLASS FACTORIES

摘要

A main drive control method for glass factories, comprising the following steps: (a) providing a first circuit breaker and a second circuit breaker on a power supply loop of an electrical motor, wherein one end thereof is respectively connected to two main drive electrical motors; (b) enabling the first circuit breaker to be connected to a municipal power supply and the second circuit breaker to be connected to a UPS power supply; and (c) enabling the first circuit breaker and the second circuit breaker to be interlocked via a mechanical interlocking mechanism, so that only one of the circuit breakers can be switched on during a normal operation. The main drive control method for glass factories solves the problem that the rotation speed of a main drive electrical motor is incorrect due to the interference on a signal. The requirement of no stop of both electrical motors when either a municipal power supply or a UPS power supply has a failure is met; and meanwhile, the two main drive control systems are respectively provided with an independent control box, thereby avoiding a man-made accident when either of these has a failure or is repaired.
