The invention relates to an operating mechanism of a back-up protector of a surge protector. As a transmission rod is connected between a rotating bracket and a movable contact rod, one end of the transmission rod is hinged with the rotating bracket through a connecting pin, the other end of the transmission rod is connected with a sliding pin, and the sliding pin is inserted into a driving waisthole of the movable contact rod; the connecting pin is sleeved with a torsional spring, and the torsional spring presses the transmission rod on the rotating support in the clockwise direction. Thus,in a closing state, if the movable contact rod pushes the transmission rod under the action of an electric repulsion force, the transmission rod can overcome the action of the torsion spring to rotatefor a certain angle in a buffering manner, tripping and opening caused by an excessive impact force on the rotary bracket and the opening and closing operation mechanism are avoided, and after the electric repulsion force disappears or decreases, under the action of the torsion spring, tripping and opening are realized; the transmission rod drives the movable contact rod to recover to the state of closing with the static contact rod, therefore, the operating mechanism of the back-up protector of the surge protector can improve working reliability of a circuit breaker, and is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to an operating mechanism of a surge protector backup protector, in particular to an operating mechanism of a surge protector backup protector applied in the field of low-voltage circuit breakers and surge protector backup protectors. Background technique [0002] In products such as low-voltage circuit breakers and surge protector backup protectors, the smoothness of the movement of the transmission mechanism of the contact device is an important factor for judging whether the operating mechanism of the switch protector and the design of the switch are reasonable. At present, the existing transmission rod directly links the moving contact rod with the rotating bracket. This disadvantage is limited by the movement range of the bracket. The force will cause a great impact on the mechanism, and it is easy to trip. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the technical proble...
