The operating mechanism of the existing circuit breaker includes a casing, and the casing is provided with an operating handle, a lever, a jumper, a lock, and a connecting rod. The operating handle is hingedly arranged with the casing, and the casing is provided with a first shaft. The lever and the lock are sleeved on the first shaft, the operating handle and the jumper are connected through a connecting rod, the lever is provided with a second shaft, and the jumper is sleeved on the second shaft It forms a hinge between the jumper and the lever. There is a bayonet on the lock, and a block is provided on the corresponding bayonet position on the jumper. It also includes a first return spring for resetting the operating handle and a second return spring for resetting the lever. , the third return spring used to reset the lock, but this circuit breaker cannot realize the function of turning on and off the L pole power line\N pole power line at the same time; and the wiring must be connected to the incoming line and load end of the product according to the requirements , can not be reversed, otherwise the product will burn out after the action

The invention relates to a field of circuit breakers and especially relates to a circuit breaker. The circuit breaker includes a housing, a movable contact, a static contact and an operation mechanism used for controlling connection and disconnection of the movable contact and the static contact. The housing is therein provided with an arc extinguish chamber. The operation mechanism includes an operation handle, a lever, a tripping piece, a lock catch and a connection rod arranged on the housing. The housing is provided with a third shaft sleeved with a torsion spring. One end of the torsion spring abuts against the lever and the other end of the torsion spring can be enabled to abut against a mechanism contact on the housing through swinging of the lever. The other end of the torsion spring is welded with a lead. Along with the engagement and the disengagement of the mechanism, the torsion spring connects and disconnects with the mechanism contact, so that functions of power on and power off of an auxiliary power source are implemented.
Description
technical field [0001] The invention relates to the field of circuit breakers, in particular to a circuit breaker. Background technique [0002] The operating mechanism of the circuit breaker is used to control the opening and closing of the moving contact and the static contact of the circuit breaker to realize the closing and opening of the circuit breaker respectively.
