Description

technical field

[0001] The invention relates to the technical field of circuit breakers, in particular to a small circuit breaker opening and closing drive device. Background technique

[0002] Miniature circuit breaker, referred to as MCB, is the most widely used terminal protection device in the electrical terminal distribution device. The opening and closing drive module is the electric operating mechanism. It is an accessory used to control the opening and closing of the MCB. It can realize the remote electric opening and closing of the circuit breaker. At present, the most commonly used method is to use the motor Acceleration and deceleration mechanism to achieve.

[0003] The patent with the publication number CN203277259U discloses an electric operating mechanism of a circuit breaker. In the second-stage gear, two coaxial gears with clutch function are used, wherein the coaxial driving wheel is first rotated forward to drive, driving The handle of the circuit breake...
