Embodiment Construction

[0024] Embodiment of the control device of the circuit breaker energy storage motor:

[0025] The control device for the energy storage motor of the circuit breaker proposed in this embodiment includes a drive circuit and a controller. The driving circuit includes an energy storage circuit, and a switching power supply is connected in series in the energy storage circuit, which is used to drive the energy storage motor to run; the controller includes a memory and a processor, and the processor is used to execute instructions stored in the memory to realize the operation of the circuit breaker energy storage motor. Control Method.

[0026] In order to realize the control method of the energy storage motor of the circuit breaker of the present invention, the circuit breaker needs to change the original internal wiring relationship, such as figure 1 As shown, the original internal wiring of the circuit breaker is that the energy storage motor M is connected in series with the co...

Abstract

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. The control method for the energy storage motor of the circuit breaker includes the following steps: before the energy storage motor is started, the power-on time of the switching power supply is detected, and if the power-on time of the switching power supply is greater than or equal to the time threshold, the energy storage motor is controlled to start. In the present invention, after the switching power supply is turned on and before the energy storage motor is started, a certain time is left to charge the capacitor, which can prevent the switching power supply from overload protection when the energy storage motor is at the maximum load, and cannot drive the energy storage motor to run, thereby improving energy storage Reliability of motor starting.

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...
