Background technique
Effect of the breaker played in distribution line is disjunction and connect circuit, more particularly, passes through contact system
The separable contact pair of a pair closure or separation realize being switched on or switched off to protect circuit and electrical equipment of electric line.When
When there is abnormal failure in route, such as when short circuit, the rapidly disjunction circuit by the separation of contact pair, to avoid equipment damage；
When overload, bimetal leaf expanded by heating promotes contact to separation and rapidly disjunction circuit.The known reason such as industry, in current-carrying
In the case of contact separation can generate electric arc, especially when disconnecting Short-Circuit High Current, the energy of electric arc is big, tight to the ablation of contact
Weight, therefore in the various device for switching such as breaker, contactor, arc-control device is usually all set to extinguish electric arc, to guarantee electricity
Device equipment operational safety.
Currently, the Chinese patent that notification number is CN207183187U discloses a kind of operating mechanism of novel breaker, it
Including shell, shell is equipped with operation handle, lever, tripping, lock, connecting rod, and housing switch mouth is hingedly arranged in operation handle
Side, the other side be equipped with the first axle body, lever, lock be set on the first axle body, through U-shaped between operation handle and tripping
Connecting rod connection, lever are equipped with the second axle body, and tripping, which is set on the second axle body, forms the hinged of tripping and lever, set on lock
There is bayonet, bayonet position is corresponded in tripping equipped with fixture block, further includes the first resetting-mechanism having for resetting operation handle, is used for
Second resetting-mechanism of restoring lever, the third resetting-mechanism for reset lock.
The operating mechanism structure of this novel breaker is simple, and after fault and contact are to separation, operation handle passes through
First resetting-mechanism is downwardly turned over along hinged place, when circuit improves and then dials up operation handle along hinged place
And position, realize contact to closure by connecting rod.When needing to circuit emergency power off, worker manual toggle manipulator is needed
Handle, by circuitry cuts；The operation handle of the operating mechanism of this novel breaker is shorter, and under dim environment, worker is dialled
Dynamic operation handle even needs to touch shell with hand, is then stirred downwards with hand along shell, finger encounters operation handle then
Operation handle is stirred downwards, however interior of shell can generate electric arc by being powered to switching to power off, in the case where arc-chutes damage,
It is easy for causing safety accident.

Wheel, the first gear are fixedly connected with drive rod, and the second gear is fixedly connected with screw rod, the first gear
Outer diameter be less than second gear outer diameter.
By using above-mentioned technical proposal, the outer diameter of first gear is less than the outer diameter of second gear, drives the in drive rod
One gear has preferable labor-saving effect during rotating, so that worker be made to drive accessory plate movement more convenient.
The utility model is further arranged to：It is fixed on the outer wall of the drive rod multiple using anti-made of rubber
Draw runner.
By using above-mentioned technical proposal, the setting of tread plate, effectively increase worker's hand and drive rod outer wall it
Between frictional force, make worker drive drive rod rotation it is more convenient.
In conclusion the utility model has the advantages that：
Rotation of drive rod makes drive rod drive screw rod rotation by steering assembly, pushes screw rod by screw thread auxiliary
It helps plate mobile toward the direction far from drive rod, the overturning of operation handle can be realized by stirring accessory plate, so that worker is not
Accessory plate can be touched easily under the premise of pedestal must be touched, and achieve the purpose that be not easy to cause safety accident.
