Embodiment Construction

[0016] Embodiments of the circuit breaker of the present invention: as Figure 1-2 As shown, it includes a circuit breaker unit and a circuit breaker operating mechanism. The circuit breaker operating mechanism includes an operating mechanism box 4, and the upper right side of the operating mechanism box 4 is connected to the transmission mechanism box 2 of the circuit breaker. Each circuit breaker unit 1 is supported by brackets 3 . A motor 5 for driving the insulating pull rod of the movable contact is installed in the operating mechanism box, and the insulating pull rod of the moving contact is located in the transmission mechanism box 2 . The operating mechanism casing 4 has three layers in the up-down direction. The upper layer of the operating mechanism casing forms a motor compartment 45 for installing the motor, and the axis of the output shaft 51 of the motor 5 extends along the left-right direction. The output shaft 51 of the motor 5 stretches out from the motor com...

Abstract

The invention discloses a circuit breaker operating mechanism and a circuit breaker and high-voltage applying the same. The circuit breaker operating mechanism comprises an operating mechanism box, a motor used for driving a dynamic contact insulating tension rod is mounted in the operating mechanism box, and the output shaft of the motor extends out of the operating mechanism box. By the arrangement that the motor is arranged in the operating mechanism box, the motor itself, a data transmission line and a power line are effectively protected, and interference caused by strong interference environment on an electromotor control system, data transmission and the like in field application are avoided; the motor is arranged in the mechanism box to be integrally formed with the mechanism box, so that the entire operating mechanism is more compact in structure and convenience in in-situ mounting and maintaining is achieved.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, in particular to a circuit breaker operating mechanism, a circuit breaker and a high-voltage switch using the mechanism. Background technique [0002] The high voltage circuit breaker is one of the important equipment in the power system, and the operating mechanism in the circuit breaker is the key component that determines its performance. The working reliability of the circuit breaker depends to a large extent on the action reliability of the operating mechanism. . The traditional circuit breaker operating mechanism has a high failure rate and poor stability, which brings great safety hazards to the safe operation of the power system. In recent years, a new type of operating mechanism that uses a motor to drive a high-voltage circuit breaker has emerged. For example, the Chinese patent with the authorized notification number CN102891034B discloses a high-voltage circuit breaker...
