Lock disconnects, and further increases stability and the safety of breaker work.
Description of the drawings
The utility model has following attached drawing：
Fig. 1 is the internal structure chart of the utility model；
Fig. 2 is the structure chart that Fig. 1 removes operating mechanism.
Specific implementation mode
As shown, the miniature circuit breaker of band disclosed by the utility model electric leakage self-checking function, including shell 11 and lead
The top of electric item 12, shell 11 is equipped with handle 1, and handle 1 is sequentially connected with the operating mechanism 4 inside shell 11, behaviour
The bottom of motivation structure 4 is connected with moving contact 5, is equipped with electromagnetic drive mechanism 10 in the lower section of handle 1 inside shell 11, electromagnetism drives
Motivation structure 10 and circuit board electrical connection are equipped with grating cover 9 inside shell 11 in the lower section of electromagnetic drive mechanism 10, in grating cover 9
It is arranged with arc extinguishing grid pieces 8, arc striking piece 6 is equipped on the right side of grating cover 9 inside shell 11, conductive bar 12 is conductive in vertically arranged
The bottom of item 12 is electrically connected with the yoke 3 being sleeved on outside electromagnetic drive mechanism 10, bottom and 7 electricity of static contact on 3 right side of yoke
Connection, the top of conductive bar 12 be bent to form to the right be laterally arranged press portion 13, fixture block 14 is installed with inside shell 11, is blocked
Block 14 is in contact with the bending place of conductive bar 12, and 14 top of fixture block is equipped with fillet, and is supported to the bending place of conductive bar 12,
The top for pressing portion 13 is contacted with leak(age) test button 2, and leak(age) test button 2 can be mounted on shell 11 up or down, shell
Electrical contact 15 is being provided at the position pressed below portion 13 inside body 11, electrical contact 15 passes through conducting wire 16 and wiring board electricity
Connection.
It when breaker is in normal "on" position, and needs to simulate drain conditions, whether detection breaker can leak electricity
In the case of separating brake when, press leak(age) test button 2, what leak(age) test button 2 was pressed down against conductive bar 12 presses portion 13, makes to press
Portion 13 is contacted with electrical contact 15, and realization yoke 3 is electrically connected with wiring board, simulates drain conditions, wiring board receives electric signal
Control electromagnetic drive mechanism 10 acts afterwards, and operating mechanism 4 is pushed to rotate counterclockwise so that moving contact 5 and static contact 7 detach, real
Existing breaker open operation, if at this time breaker can normal separating brake, illustrate that the earth leakage protective device of circuit breaker internal can be just
Often work, if at this time breaker cannot normal separating brake, illustrate that the earth leakage protective device of circuit breaker internal is no longer valid, need
Repair or the breaker more renewed carry out detection of electrical leakage to breaker by periodically pressing leak(age) test button 2, come true
Recognize whether breaker earth leakage protective device can work normally, further increases stability and safety that breaker uses.
