Circuit breaker operating mechanism and circuit breaker and high-voltage switch applying same

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. 本发明公开了种断路器操动机构及使用该机构的断路器、高压开关，其中断路器操动机构包括操动机构箱体，操动机构箱体内安装有用于驱动动触头绝缘拉杆的电动机，电动机的输出轴伸出所述操动机构箱体
