Description

Novel small-sized breaker

Technical field

The present invention relates to the breaker of manually and automatically integral type divide-shut brake, is specially that a kind of the automatic of miniature circuit breaker is divided Closing device.

Background technology

Miniature circuit breaker is a kind of switching device for the various occasions for being widely used in production and living, and user terminal is generally all matched somebody with somebody There is miniature circuit breaker device, with information-based development, intelligent grid is growing perfect, and the mode of the electricity charge is collected to user No longer visited as before by meter reading person and meter reading and collect the electricity charge；The electricity charge are collected to user now generally take and remotely collect electricity The mode taken, user can be by pinpointing business hall electricity payment or in online business hall electricity payment, can also be by pre- Certain electricity pre-purchase in the mode of payment, and when subscriber arrearage, the breaker of user terminal is automatic by control device control Separating brake, after treating user's electricity payment, it is customer power supply that control device controls the breaker closing of user terminal again；

Such as the Chinese patent literature of Application No. 201610664948.6 discloses automatic point of a kind of miniature circuit breaker Closing device is using base, closing lid, transmission mechanism and control control module on base, action link rod, the biography Motivation structure includes driving motor and train of reduction gears, the drive bevel gear at driving motor engagement train of reduction gears end, active conical tooth Wheel engagement driven wheel of differential, while driven wheel of differential top, the folding gear by driven wheel of differential transmission, the folding gear Middle part is provided with a kinematic link, is connected through mounting seat with the miniature circuit breaker operation handle of required control, described dynamic The end vertical for making connecting rod is provided with action driving lever, the action driving lever go directly the miniature circuit breaker side attached together arc groove in, Miniature circuit breaker cannot artificially close a floodgate when in open position, although the device has simple in structure, working stability, transmit negative The features such as lotus is larger, but in intelligent grid, in various complicated circuits controls, can only simply control breaker open operation and Combined floodgate has been unable to meet intelligent grid demand.

The content of the invention

It is an object of the invention to overcome in the prior art the automatic switching off/on device of miniature circuit breaker cannot meet control and Complicated release unit is instructed, because the displosure one enriches the control instruction of breaker, has greatly reinforced the safe to use of product Performance, makes that it is suitable in various complicated circuit environment.

A kind of automatic switching off/on device of miniature circuit breaker, including breaker, the left surface of the breaker are equipped with lid, institute State and control module, motor are installed on the left of lid, the motor is equipped with worm screw, and gear set is connected with the worm screw, described The upper end of gear set is connected with universal driving shaft, and handle gear is equipped with universal driving shaft, and the positive middle part of breaker, which is equipped with, threads off Bar, the right side of the release lever are equipped with base；

The gear set includes turbine, the first travelling gear, the second travelling gear and the 3rd travelling gear, and described The first detection switch, the second detection switch and the 3rd detection switch are engaged with two travelling gears, first travelling gear Front is equipped with driving wheel, is engaged with the second travelling gear on the driving wheel, second travelling gear be by dropout boss with Instruct boss to form, at the center of second travelling gear engaging have the 3rd travelling gear, and second travelling gear with 3rd travelling gear is coaxial, and the turbine is equipped with central shaft.

Further, the handle gear is equipped with divide-shut brake instruction boss, and separating brake instruction boss and described the Three detection switch are not exclusively drive connection.

Further, the counter clockwise direction of the handle gear be disposed with the 3rd detection switch, the first detection switch, Second detection switch, and the divide-shut brake instruction boss when rotating counterclockwise successively with the 3rd slowdown monitoring switch, the first detection switch, the Two detection switch contact.

Further, the 3rd travelling gear, which is equipped with, performs boss, and described instruction boss and the execution boss are suitable When dial do not contact.

Further, second travelling gear is coaxial with the 3rd travelling gear, and second travelling gear with By performing boss and described instruction boss coupled movements between 3rd travelling gear.

Further, when the divide-shut brake instruction boss on the handle gear pushes down three detection switch, the motor stops Rotation stop is moved.

The present invention operation principle be：Breaker is in open position, the divide-shut brake instruction boss pressure on its handle gear Firmly the 3rd detection switch, makes it continuously send out breaker and be in " open position " signal and gives breaker control module；

1. when breaker receives combined floodgate order, motor rotates forward, and drives turbine to rotate counterclockwise by worm screw, then turbine Drive the first travelling gear to rotate clockwise it, and then drive the second travelling gear to rotate counterclockwise it, and the second transmission The instruction boss of gear promotes the execution boss of the 3rd travelling gear, the 3rd travelling gear is rotated counterclockwise together, and the 3rd passes Moving gear is engaged by gear and drives handle gear, and divide-shut brake instruction boss thereon leaves the 3rd detection switch, when its rotation During to the first detection switch, the first detection switch sends " closing position " signal to breaker, and motor reversal, passes through gear at this time Engagement drives the second travelling gear to rotate clockwise, and at this moment on the instruction boss and the 3rd travelling gear on the second travelling gear Execution boss up time dial do not contact, therefore the 3rd travelling gear can not be promoted, when the second travelling gear turns to its instruction When boss pushes down the second detection switch, the second detection switch sends " combined floodgate resigning position " signal, and motor stalls, break at this time Road device is in "on" position, while can manual brake separating and closing by hand；

2. when breaker receives separating brake order, motor continues to invert, and the dropout boss on the second travelling gear promotes Release lever, so as to promote breaker open operation, circuit breaker handle drives handle teeth wheel to return to initial open position, on its handle gear Divide-shut brake instruction boss push down the 3rd detection switch, the 3rd detection switch sends " open position (separating brake locking position) " letter Number, motor stalls, breaker can not closing by hand at this time.

The beneficial effect of the device is：1. as a result of turbine, worm screw, the first travelling gear, the second travelling gear, Three travelling gears, handle gear etc. have six gear transmission structures altogether.By motor forward and reverse come control breaker from Dynamic circuit connector lock and automatic brake separating, and then realize the device remote control.

2. due to using the first detection switch, the second detection switch and the 3rd detection switch control signal transmission, realizing disconnected Road device automatic closing, automatic closing resigning, automatic brake separating, automatic brake separating such as lock at the instruction, enrich the control instruction of breaker, The usage safety performance of product is greatly reinforced.

It is 3. convex by performing boss and instruction between them due to coaxial with the 3rd travelling gear using the second travelling gear Platform coupled movements, and then ensure that the device can accurately control the breaker open operation and combined floodgate in complicated circuit, ensure electricity consumption Safety, reduces false touch and the artificial possibility for forcing to close a floodgate, reduces electric shock risk, and then realize breaker automatic brake separating and conjunction Lock.
