Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] The high-voltage circuit breaker provided by the present invention is a circuit breaker driven by a motor, and the circuit breaker is provided with a motor-driven operating mechanism, such as figure 1 As shown, and the power supply system for the motor-driven operating mechanism. For ease of description, in this embodiment, a 126kV sulfur hexafluoride circuit breaker is used as an example for the high voltage circuit breaker.

[0016] Such as figure 2 As shown, the power supply system includes a transformer device 101, a rectifier device 102, an energy storage device 103, a rectifier device 104, a rectifier device 105, and a rectifier device 106. The input end of the transformer device 101 is connected to a three-phase 380V alternating current. Transform the three-phase 380V AC power, transform the three-phase 380V AC power to generate the required ...

Description

technical field [0001] The invention relates to a power supply system for a motor-driven operating mechanism of a high-voltage circuit breaker and a high-voltage circuit breaker. Background technique [0002] Due to the high failure rate, poor stability and complex mechanical structure of the traditional high-voltage circuit breaker operating mechanism, it brings great safety hazards to the safe operation of the power system. In recent years, a new type of operating mechanism using a motor to drive a high-voltage circuit breaker has been proposed, which can solve the above problems. [0003] The Chinese invention patent with the application number 201210348752.8 discloses a high-voltage circuit breaker machine operating mechanism; the Chinese invention patent with the application number 201310297673.3 discloses a circuit breaker and its operating mechanism; A high-voltage switch operating mechanism and a high-voltage switch using the mechanism. These related patents only d...
