Abstract

The invention discloses a manual and motor-driven integrated operating mechanism of a breaker. The manual and motor-driven integrated operating mechanism comprises a first fixing plate and a second fixing plate which are installed on a middle cover of the breaker, a movable separation plate is arranged below the first fixing plate, one end of the separation plate is connected with the first fixing plate through a locating pin, a manual/automatic switch is arranged at the other end of the separation plate, a motor is arranged on the separation plate, a gear is connected onto a main shaft of the motor, the second fixing plate is arranged on one side of the first fixing plate, a sliding plate is arranged on the second fixing plate, a rack matched with the gear is fixed on the sliding plate, and the sliding plate is in transmission connection with an operation handle through a linkage component. The operating mechanism of the breaker is installed on the middle cover of the breaker, and the handle can be operated by directly operating the breaker. The manual and motor-driven integrated operating mechanism is simple and reliable in mechanism, convenient to operate and small in size, can achieve automatic manual reliable switching and prolongs mechanical service life.

Description

technical field [0001] The invention relates to an operating mechanism for a circuit breaker, in particular to an integrated operating mechanism for a circuit breaker that can be operated manually and electrically. Background technique [0002] At present, circuit breakers are necessary products for power transmission and switching in power supply systems. The operating mechanism first realizes spring energy storage and then opens and closes to complete. Generally, to achieve this action, it is necessary to install two sets of manual and electric operating mechanisms in the circuit breaker. However, the new generation of circuit breakers currently designed and produced are compact in structure and small in size. Due to the complex structure and large size of the traditional manual and electric operating mechanisms, it is not enough space to install two operating mechanisms inside the circuit breaker to realize the switching of power.
