Description
Technical field
This utility model is related to Low Voltage Electrical Apparatus, more particularly to a kind of omnipotent breaker.
Background technology
Omnipotent breaker realizes product on/off switch by operating mechanism.During omnipotent breaker manual energy storage, using outer
Power rotates energy accumulation handle, drives V-arrangement axle to rotate by the ratchet on the pallet and operating mechanism on energy accumulation handle, makes operating mechanism
Energy-stored spring compresses, and completes manual energy storage.After operating mechanism releases energy, ratchet returns to initial position, the energy accumulation handle in initial position
On pallet and operating mechanism on ratchet between do not transmit torque, pallet and ratchet need to be made after energy accumulation handle is turned an angle
Interlock, transmit torque.At present, when operating mechanism releases energy, because the reason such as parts machining error, mismatch error causes ratchet to turn
It is dynamic excessive, ratchet is contacted with the pallet buckle side on energy accumulation handle, now need not open by energy accumulation handle is turned an angle
Beginning energy storage, due to gap very little between original state energy accumulation handle and mask, stirs energy accumulation handle without adequate space, it is difficult to complete
Stored energy operation.
Omnipotent breaker is rotated by motor band pneumatic operating mechanism V-arrangement axle and realizes electric energy-stored, electric energy-stored process
Rotate for motor energization, motor gear transmission reduces rotating speed and is transferred to blind in afterbody gear (aluminium dish), aluminium dish
Hole (or through hole) is coordinated with operating mechanism V-arrangement axle, is transmitted torque to operating mechanism, is realized operating mechanism energy storage.At present, in aluminum
One and operating mechanism V-arrangement shaft section identical blind hole (or through hole) are processed on disk, is coordinated with V-type axle by blind hole (or through hole)
Transmitting torque, the aluminium dish are the entirety of an aluminum profile extrusion, because Product Assembly needs, are coordinated for gap between aluminium dish and V-arrangement axle,
In transmission process, aluminium dish is linear contact lay with V-arrangement between centers, motor aluminium dish blind hole (or through hole) abrasion during electric energy-stored
Greatly, the life-span is low.
The major loop of omnipotent breaker is divided into N/A/B/C tetra- mutually or A/B/C three-phases, per phase major loop by static contact and
Moving contact two parts are constituted.The big axis of rotation of operating mechanism during breaker closing, along driving moving contact edge to rotate by connecting rod
The heart is contacted with static contact after turning an angle, and major loop is connected.During combined floodgate, the touch spring of moving contact is contacted in sound silver point
Continue compression afterwards, form the excess of stroke, increase the end pressure of contact, to meet the performance requirement of product.At present, due to air circuit breaker
Device initiating structure design reasons, in the case of using identical parts, can differ than B away from remaining phase excess of stroke of B phases, exist
The excess of stroke is not enough, the hypodynamic risk of moving contact final pressure.
