US 2017/0324355 A1 · MAIN DRIVE CONTROL METHOD FOR GLASS FACTORIES

Abstract

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.

A main drive control method for glass factories, comprising:

(a) providing a first circuit breaker and a second circuit breaker on a power supply loop of an electrical motor, wherein one end of the first circuit breaker and one end of the second circuit breaker are connected to two main drive electrical motors respectively;
(b) enabling the first circuit breaker to be connected to a municipal power supply and the second circuit 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 one of the circuit breakers could merely be switched on during a normal operation.
