Shown in Fig. 4-7, the working principle of contactor of the present invention is as follows:
Piecemeal permanent magnetism 8 generates magnetic field, forms two closure magnetic flux paths by the pole N and returns to the pole S, one goes out from permanent magnetism 8
Hair returns to permanent magnetism 8 via magnetic guiding loop 7, dynamic iron core 5, static iron core 4, upper magnetic cylinder lid 1, magnetic cylinder 2, and generation makes dynamic iron core 5, static iron core 4
Between air gap reduce electromagnetic attraction F1；Another is returned from permanent magnetism 8s via magnetic guiding loop 7, dynamic iron core 5, lower magnetic cylinder lid 3, magnetic cylinder 2
To permanent magnetism 8, the electromagnetic attraction F for reducing 3 dynamic iron core 5, lower magnetic cylinder lid air gaps is generated2.In the case of separating brake, dynamic iron core 5,
Air gap between static iron core 4 is much smaller than 3 dynamic iron core 5, lower magnetic cylinder lid air gaps, so F1>F2, it is small that dynamic iron core 5 is maintained at air gap
That side, overcome the pressure F of switching-in spring 9NAnd the self-closing power of vacuum interrupter, contactor are in release conditions.
Have baffle 15 on 16 disk of piston, under have reset spring 18.In the case of separating brake, by the pressure F of reset springN' make
With making contactor auxiliary driving structure be maintained at release conditions.
After coil 6 powers on, via upper magnetic cylinder lid 1, magnetic cylinder 2, lower magnetic cylinder lid 3, dynamic iron core 5, static iron core 4 generate with via leading
Magnet ring 7, dynamic iron core 5, static iron core 4, upper magnetic cylinder lid 1, magnetic cylinder 2 return to the flow direction of permanent magnetism 8 on the contrary, with via magnetic guiding loop 7, dynamic
Iron core 5, lower magnetic cylinder lid 3, magnetic cylinder 2 return to the identical magnetic flux of flow direction of permanent magnetism 8, weaken 4 dynamic iron core 5, static iron core gas
Gap magnetic flux, electromagnetic attraction F1Reduce therewith, as electromagnetic attraction F2With the self-closing power of equidirectional vacuum interrupter, switching-in spring elastic force
FNThe sum of be greater than F1When, dynamic iron core 5 drives pull rod 30, insulated part structure, moving contact 25 to move downward, and closes a floodgate until being attracted, even
The major loop conducting connect.
In the case of closing a floodgate, 3 dynamic iron core 5, lower magnetic cylinder lid air gaps are much smaller than the air gap between dynamic iron core 5, static iron core 4
, so F2>F1, dynamic iron core 5 is maintained at that small side of air gap, in the pressure F with switching-in spring 9NAnd vacuum interrupter from
It closes under the collective effect of power, contactor is in attracting state.
When major loop goes wrong tripping, in above-mentioned triggered as normal signal enabling coil 6, the non-normal ON feelings of probe of contactor
Under condition, starts auxiliary driving structure immediately and pneumatically closed a floodgate.When firing circuit provides trigger signal, gas generator is ignited,
Bulk gas is generated in cylinder in short time, as the thrust gas F for acting on cylinder inner wall3Greater than the pressure of reset spring 18
F′N, electromagnet portion magnetic force F1With the resultant force of the self-closing power of vacuum interrupter, unique movable member piston 16 will be pushed to overcome reset
The pressure F ' of spring 18NIt drives pull rod 30, dynamic iron core 5, insulated part, moving contact 25 to move downward, closes a floodgate until being attracted, connection
Major loop conducting.
Above-mentioned electromagnetic principle can be used in the present invention, two kinds of driving methods of pneumatic principle close a floodgate contactor, it is ensured that contactor
It reliably closes a floodgate when major loop goes wrong.
