Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings: as it can be seen, small-sized electric leakage reclosure breaker, bag
Include breaker unit 2 and for controlling the reclosing unit 1 of described breaker unit 2 divide-shut brake, also include for described disconnected
Road device unit 2 carries out earth leakage protective electric leakage trip unit 3.This utility model provides small-sized electric leakage reclosure breaker, including
Breaker unit and for controlling the reclosing unit of described breaker unit divide-shut brake, also includes for described chopper list
Unit carries out earth leakage protective electric leakage trip unit.This miniature circuit breaker is provided simultaneously with leak electricity tripping function and automatic reclosing merit
Can, use convenient.
In the present embodiment, as it can be seen, described reclosing unit 1 includes that the first housing 11, described first housing 11 set
Have and drive motor 111 and driven the rotation dish 112 of rotation by described driving motor 111, described first housing 11 be provided with for
The groove 113 that dropout pin 22 passes through, described breaker unit 2 includes operating handle 21, described operation handle 21 is coaxially provided with
The power transmission shaft 23 of synchronous axial system, described power transmission shaft 23 part stretches into described first housing 11 and is provided with STATEMENT OF FEDERALLY SPONSORED 24, described rotation
On dish 112, side is provided with protuberance 1121, and when described rotation dish 112 includes rotating backward, its protuberance 1121 promotes described dropout
Pin 22 makes the primary importance of breaker open operation, when rotating forward by drive STATEMENT OF FEDERALLY SPONSORED 24 make breaker closing the second position and
The 3rd initial position.When chopper is off, and moving contact separates with static contact, the dropout being connected with moving contact rack
Axle is below.When automatic reclosing miniature circuit breaker obtains signal, electric motor starting, and drive motor axle gear rotates, thus
Drive turn disc.Bevel gear drives STATEMENT OF FEDERALLY SPONSORED, thus starts to close a floodgate.When turn disc is to when specifying position, and motor stops
Spline is moved, breaker closing complete (i.e. the second position), and after closing a floodgate, motor rotates backward, by turn disc to the
Shutting down behind three positions, making process is complete.
When chopper is in "on" position, moving contact contacts with static contact, when automatic reclosing miniature circuit breaker obtains letter
Number, motor starts to rotate backward, and drives rotation dish to rotate backward, the dropout sheet collision trip shaft on rotation dish, makes trip shaft move
Dynamic, trip shaft is connected to moving contact of breaker support, and chopper starts to thread off under the effect of internal spring force.When trip shaft is moved
Dynamic, drive moving contact rack to move, thread off rapidly under the effect of chopper inner spring power, while dropout, due to chopper
Handle separating brake, thus band moving axis and clutch rotate.When turn disc to primary importance, motor stalls.Work as rotation
Dish arrives specific bit and postpones, and motor rotates forward again, drives rotation dish to return to the 3rd position, closes a floodgate complete.
In the present embodiment, as it can be seen, be correspondingly provided with pushing block 241 with described protuberance 1121 in described STATEMENT OF FEDERALLY SPONSORED 24.
Being respectively arranged with 2 projections between dropout gear and STATEMENT OF FEDERALLY SPONSORED, when dropout gear is in three positions when, STATEMENT OF FEDERALLY SPONSORED can be free
Rotate, i.e. chopper can not limit with manual brake separating and combined floodgate.When motor-driven gear rotates, the projection on dropout gear
The projection in STATEMENT OF FEDERALLY SPONSORED will be promoted, it is achieved the rotation together with STATEMENT OF FEDERALLY SPONSORED of dropout gear, when dropout pinion rotation is to closing position
The when of putting, clutch band moving axis is by breaker closing.When dropout gear returns to primary importance, handle is free to again
Divide-shut brake.
In the present embodiment, as it can be seen, described rotation dish 112 is provided with Magnet 1122, in the first housing 11, it is provided with line
Road plate, described wiring board is correspondingly provided with three magnetic-inductive devices with described Magnet 1122.Dropout gear has a groove,
A Magnet is placed in the inside, produces magnetic field.There are 3 magnetic-inductive devices (first, second and third position the most mentioned above) in the circuit board
Receive magnetic field.When dropout gear forwards corresponding position to when.Magnetic-inductive device will receive magnetic signal, thus accurately controls
The position of dropout gear processed.
In the present embodiment, as it can be seen, described electric leakage trip unit 3 includes the second housing 31, described second housing 31
Being provided with electrical connection ZCT and magnetictrip 32, described magnetictrip 32 front end is correspondingly provided with push rod 33, described top
Bar 33 is correspondingly arranged with described dropout pin 22, and described second housing 31 is additionally provided with the elastic reset resetted for described push rod 33
Part.ZCT senses electric leakage signal, and wiring board, to coil electricity, produces magnetic field so that the ferrum inside magnetictrip
Core becomes Magnet and attracts each other, thus moves, and promotes dropout push rod, and dropout push rod promotes trip shaft, makes circuit breaker tripping.
In the present embodiment, as it can be seen, described elastic reset part is torsion spring.May be otherwise the elastic reset for other
Part, such as extension spring, stage clip etc., use torsion spring to be easily installed, use.
Embodiment is not construed as restriction of the present utility model, but any based on changing that spirit of the present utility model is made
Enter, all should be within protection domain of the present utility model.
