Description
Technical field
The present invention relates to a kind of low-voltage electrical apparatus, relate in particular to the automatic switching off/on device of a kind of miniature circuit breaker.
Background technology
Miniature circuit breaker, also known as miniature circuit breaker, is widely used in electric wiring transshipping, short circuit and overvoltage, under-voltage guarantor
Protecting, due to the appearance of intelligent grid, the divide-shut brake of miniature circuit breaker must have the function of far distance automatic controlling, the most this
Conform to the automaton in miniature circuit breaker side in succession occur, at present, the control dress of the automatic divide-shut brake of miniature circuit breaker
Putting and mainly have two classes, a class is to use worm and gear to drive, and a class is to use angular wheel to drive.
Chinese patent literature CN105304421A discloses the control driving means of a kind of miniature circuit breaker, uses worm gear
Worm drive, it employed technical scheme comprise that the worm screw of motor side is meshed with bevel gear set, bevel gear set and straight-tooth wheels phase
Engagement, straight-tooth wheels are meshed with drive mechanism, and drive mechanism drives and controls dropout actuator, by controlling motor in work
Rotation thus control dropout actuator and rotate from different directions, by the connection miniature circuit breaker that dropout actuator is centrally disposed
The square shaft of handle is to reach to control the purpose that miniature circuit breaker automatic brake separating closes a floodgate, and this device driving gear set is more, and structure is multiple
Miscellaneous, the load that can transmit is less.
Chinese patent literature CN104576235A discloses the auto recloser of a kind of miniature circuit breaker, uses cone
Shape gear drives, and it the technical scheme is that and includes base, upper cover, drive mechanism, tripping mechanism, electronic-controlled installation, institute
The drive mechanism stated uses the bevel gear that bevel gear is meshed with bevel gear, controls the forward and reverse of motor and rotate through in work
The connecting shaft connecting miniature circuit breaker operation handle that arranges on bevel gear end face thus realize miniature circuit breaker separating brake, combined floodgate
Purpose, but when realizing far distance automatic reclosing, it is provided with a special tripping mechanism being made up of electric magnet, cause this dress
Put the most complicated.
Summary of the invention
It is an object of the invention to overcome the middle-size and small-size chopper of the prior art baroque drawback of automatic switching off/on device,
Open a kind of simple in construction, working stability, the automatic switching off/on device of miniature circuit breaker that transfer charge is bigger.
The automatic switching off/on device of a kind of miniature circuit breaker, including base, closing lid, drive mechanism be arranged on base
Control circuit board, action link rod, it is characterised in that: described drive mechanism includes driving motor and train of reduction gears, is arranged on
The driven wheel of differential that the drive bevel gear of driving motor train of reduction gears end engages with drive bevel gear, is arranged on from mantle tooth
The folding gear that wheel top is engaged with driven wheel of differential, in the middle part of described folding gear, axial restraint has kinematic link, described
Kinematic link operates handle through base with the miniature circuit breaker of required control and is connected.
Arranging further, described driven wheel of differential is axially disposed is three parts, and middle part is provided with and described initiative taper
The driving cog that gear is meshed, front portion is set to incomplete travelling gear, is provided above with several driving cog, described not exclusively
The outside of travelling gear is provided with erecting bed, and described driven wheel of differential rear portion is set to turning wheel, sets on described turning wheel
Being equipped with one and stir tooth, the rear side at described turning wheel is provided with erecting bed, described driven wheel of differential be provided centrally with install
Axis hole, puts driven wheel of differential conjunction in described base and closing lid by installing axle and described erecting bed.
Arrange further, described folding gear be provided centrally with front and back installing axle, by described base plate and closing lid
Installing groove conjunction and put in base and closing lid, described folding gear is set to partial gear, and described folding gear is provided with
Several driving cogs that travelling gear incomplete with on described driven wheel of differential is meshed, described installation axle be provided centrally with peace
Fill the square hole of described kinematic link.
Arranging further, described action link rod is set to hook shape, and middle part is provided with installation axle, and described action link rod leads to
Crossing the rotation of installation axle to be arranged in base and closing lid, the non-hook end of described action link rod is vertically installed with action driving lever.
The operation principle of the automatic switching off/on device of described miniature circuit breaker is as follows:
When miniature circuit breaker is in the case of closing a floodgate, after driving motor obtains the sub-gate signal that control circuit board is sent here, pass
Galvanic electricity owner's dynamic bevel gear is rotated clockwise, and the driven wheel of differential engaged is rotated clockwise, described action
Connecting rod is under the effect of driven wheel of differential back side turning wheel, and the action driving lever of action link rod end is in the arcuate groove of miniature circuit breaker
Move upward and be in gate-dividing state, drive the operation handle of miniature circuit breaker automatically to thread off, if the most artificial removes combined floodgate
Operation handle, due to the effect of action driving lever, operation handle will be unable to close a floodgate；When miniature circuit breaker is in open position, when
After obtaining the switching signal of control circuit board, driving motor drive bevel gear continues to be rotated clockwise, engage from
Dynamic bevel gear is rotated clockwise, simultaneously described in action link rod under the effect of driven wheel of differential back side turning wheel, action
The action driving lever of connecting-rod head moves downward in the arcuate groove of miniature circuit breaker and is in closing position, now described folding tooth
Wheel counterclockwise rotates, and the power transmission shaft being in folding gear centre drives the operation handle of miniature circuit breaker to close a floodgate,
In the case of this, if miniature circuit breaker is under loaded line is in overload, short circuit, overvoltage, the abnormal conditions such as under-voltage, do not interfere with
The trip protection of miniature circuit breaker, does not interferes with separating brake and the combined floodgate artificially to miniature circuit breaker simultaneously yet.
The automatic switching off/on device of miniature circuit breaker of above structure is had the beneficial effect that this automatic divide-shut brake structure
Simply, stable and reliable in work, under the normal working condition of miniature circuit breaker, do not interfere with its defencive function, work as miniature circuit breaker
Can not close a floodgate by force after being in control separating brake, be particularly suitable in intelligent grid using, simultaneously because use conical tooth wheels to pass
Dynamic, the load transmitted is relatively big, and the most jumbo multipole circuit breaker uses.
