Device, for single-phase, three-phase short circuit, the overload protection of below 125A, including monopole 1P, two pole 2P, three pole 3P, quadrupole 4P.It is disconnected
Road device releasing structure is used for the rapid-releasing of far distance controlled breaker, and circuit breaker tripping structure generally uses operation electriomagnet machine
Structure.Electric motor operating mechanism is used for the divide-shut brake of operating breaker, is reached by the position of the cam inside motor-operating mechanism
Splitting or integrating, breaker can guarantee that breaker reliably closure and disconnection when being operated with motor drive mechanism.
The motor-operating mechanism of breaker is a kind of annex for electronic separating brake and combined floodgate breaker at a distance, electronic behaviour
There are two kinds of electric motor operating mechanism and operation electriomagnet mechanism as mechanism.Electric motor operating mechanism is usually used in mold cased circuit breaker,
Splitting or integrating is reached by the position of the cam inside motor-operating mechanism, breaker can guarantee that open circuit when being operated with motor drive mechanism
Device reliably closure and disconnection.But complex to ensure correct its structure of order of operation and control, reliability is low, high cost,
Simultaneously switch off speed generally relatively slow, and nor thread off.
A kind of motor-operating mechanism of breaker, its skill for using are disclosed in Chinese patent literature CN203277259U
Art scheme is, this kind of motor-operating mechanism of breaker, including rotation dish, slide plate and a semi-circular teeth disk, the rotation dish one
Side sets one handle, and the rotation dish opposite side is extended a rotating shaft, a fixing groove, the semicircle are opened up in the rotating shaft
In fluted disc insertion fixing groove and with rotation seat socket on the same axis, a breach is opened up in the rotation dish, the slide plate
One end is provided with promoting button, and a lock- receiving aperture is opened up in the promoting button, and the other end of the slide plate is provided with snap fit, works as cunning
When plate is moved rearwards by, snap fit is buckled in the breach of rotation dish.But can be manual or artificial in the breaker of the technical scheme
Combined floodgate separating brake, it is impossible to ensure when that can prevent failure from not releasing or not paying dues after being tripped caused by there is catastrophe failure or arrearage
Artificially close a floodgate by force, so as to safety cannot be ensured or prevent arrearage from sneaking current.
A kind of biography of electric operation mechanism for miniature breaker is separately disclosed in Chinese patent literature CN102290298A
Motivation structure, includes housing, and motor is provided with housing, and the handle that can be rotated around fixing axle, handle are provided with housing
Lower end is provided with gear and in housing, is provided with the output shaft of the motor and turns wall and matched driving tooth
Wheel, driving gear engages with gear, to turn and be provided with gap between wall and the corollary apparatus of driving gear.The technical scheme cannot also be protected
Artificially closing a floodgate by force when that can prevent failure from not releasing or not paying dues after being tripped caused by there is catastrophe failure or arrearage is demonstrate,proved, from
And safety cannot be ensured or prevent arrearage from sneaking current.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of can direct drive by motor makes breaker rapid-releasing
And the circuit breaker tripping structure that cannot be closed a floodgate by handle.
In order to solve the above technical problems, the technical solution adopted by the present invention is, the circuit breaker tripping structure includes threading off and drives
Moving part and dropout revolving meber；The dropout actuator is respectively provided with axis hole and with identical axle center, institute with the dropout revolving meber
Dropout actuator is stated to be movably connected by fixing axle with the dropout revolving meber；The dropout actuator is axially extended and is provided with
First axle sleeve, the first axle sleeve side is extended transversely with drive rod；The dropout actuator opposite side and described first
Axle sleeve extends in transverse direction jointly has the first holder and the second holder, in first holder and second folder
There is rotary space between gripping member；The dropout revolving meber extends with platform in transverse direction, and the platform is axially disposed
There is pivoted lever, the pivoted lever is embedded between first holder and second holder so that pivoted lever can be embedding
Enter and turned round in the rotary space；The dropout revolving meber includes rotating part, and the rotating part is in axial direction provided with
Connecting shaft, the connecting shaft has the connecting bushing being socketed in the connecting shaft, and the connecting bushing is connected with the platform
Connect, the connecting shaft is movably connected with the connecting bushing.
Using above-mentioned technical proposal, dropout actuator is by the revolution that is embedded between the first holder and the second holder
Bar is turned round in the rotary space formed by the first holder and the second holder so as to drive dropout revolving meber to slide, and is made
Breaker rapid-releasing, threads off and power off；In addition directly dropout actuator can be driven to move by motor, so as to realize using
Motor directly drives breaker rapid-releasing；After the rotating part of dropout revolving meber moves to circuit breaker tripping position, then can
It is maintained on trip positions, so that the lock of breaker is constantly in released state, it is impossible to close a floodgate, it is ensured that occurring seriously
Artificial when can prevent failure from not releasing or not paying dues after tripping operation caused by failure or arrearage being closed a floodgate by force, so that it is guaranteed that safety or
Person prevents arrearage from sneaking current.
Further improvement is that the circuit breaker tripping structure includes travelling gear, and the travelling gear can by drive rod
Drive the dropout actuator.Travelling gear drives dropout actuator to rotate by drive rod, and dropout actuator drives dropout again
Revolving meber is slided, so as to realize threading off.
Further improvement is that the travelling gear axially extends has arc boss, and the travelling gear passes through institute
Arc boss is stated to be in contact with the drive rod so as to drive and limit the dropout actuator.Can be limited by arc boss
The position of dropout actuator, so that the position of dropout revolving meber is limited, so as to realize that lock is maintained on trip positions so that disconnected
The lock of road device is constantly in released state, it is impossible to close a floodgate, and further better ensures that and cause there is catastrophe failure or arrearage
Tripping operation after artificial when can prevent failure from not releasing or not paying dues close a floodgate by force, so that it is guaranteed that safety or preventing arrearage from stealing
Electricity.
Further improvement is that the dropout revolving meber is provided with the second axle sleeve vertically, and second axle sleeve is to extension
Stretch and be provided with rotator, the rotator is parallel with the platform；The rotating part has the first groove, the rotating part both sides
Edge is in circular arc；And the both sides of the rotating part in transverse direction extend be provided with arc platform.The Main Function of rotator
Be the dropout revolving meber after stress rotate counterclockwise, rotating part limited by rotator and the housing being in contact with rotator and
Deformation, so as to a clockwise restoring force can be produced after rotating part loses counterclockwise rotating force, so that extensive after threading off
Again more rapidly.
Further improvement is, including motor, bevel gear set and spur gear group；The motor is oblique with described by worm screw
