Circuit breaker phase-selection opening and closing device and control method

Abstract

The invention discloses a circuit breaker phase-selection opening and closing device and a control method. The circuit breaker phase-selection opening and closing device comprises a circuit breaker and a circuit breaker opening and closing control system, and is characterized in that the circuit breaker comprises a first pole column, a second pole column and a third pole column, the first pole column, the second pole column and the third pole column are internally provided with a pressure sensor, the first pole column, the second pole column and the third pole column of the circuit breaker areprovided with a displacement sensor at the bottom, and the opening and closing control system comprises a main controller, a temperature sensor, a timer, a first driving circuit, a second driving circuit, a third driving circuit, a first motor, a second motor, a third motor, a wireless communication circuit, a first opening and closing operating mechanism, a second opening and closing operating mechanism and a third opening and closing operating mechanism. The circuit breaker phase-selection opening and closing device has a function of real-time compensation and a characteristic of stable opening and closing time.

Description

technical field [0001] The invention relates to the technical field of manufacture and use of high voltage circuit breakers, in particular to a circuit breaker phase selection opening and closing device and control method with compensation function and stable opening and closing time. Background technique [0002] As we all know, with the emergence and wide application of ultra-high voltage and ultra-high voltage transmission lines, the voltage and inrush current generated by circuit breakers in the process of switching loads and breaking short-circuit currents often endanger the insulation of equipment and the stability of power systems. It is necessary to control and optimize the opening and closing operation process of the circuit breaker. To achieve precise control and achieve ideal results, it is very important to ensure the discreteness and stability of the inherent action time of the circuit breaker mechanism. Contents of the invention [0003] The present invention...
