Abstract

The invention relates to a control method and device for an energy storage motor of a circuit breaker, and belongs to the technical field of direct-current motors. The control method comprises the steps that in the energy storage process, the working current and voltage of the energy storage motor are obtained in real time, and the actual operation power of the energy storage motor is obtained according to the working current and voltage of the energy storage motor; when the voltage of the energy storage motor is suddenly reduced or the actual operation power of the energy storage motor is greater than a power set high value, the energy storage motor is controlled to operate in a power reduction manner so as to ensure normal operation of the energy storage motor; the power setting high value is set according to the loading capacity of the switching power supply. According to the invention, the working current and voltage of the energy storage motor in the energy storage process are monitored; when the actual operation power of the energy storage motor is larger than the power set high value, namely when the power of the energy storage motor exceeds the limit, the operation power ofthe energy storage motor is reduced, it is guaranteed that the switching power supply can independently drive the energy storage motor to operate, and the operation power of the energy storage motoris regulated and controlled.

Description

technical field [0001] The invention relates to a control method and device for a circuit breaker energy storage motor, belonging to the technical field of direct current motors. Background technique [0002] With the application of electric energy more and more widely, circuit breakers play an indispensable role in the distribution network at present, and its electric switching characteristics make distribution automation possible. The spring-operated circuit breaker relies on the motor operating mechanism to store energy on the spring, so as to perform continuous opening and closing operations. Once the energy storage cannot be completed, the continuity of the electric opening and closing of the circuit breaker will be destroyed, which will affect the automation of the distribution network. The traditional operating mechanism is only designed according to a predetermined opening and closing mode, and the action process is uncontrollable. Therefore, someone proposes a cont...
