Get up around circlewise, forms two magnetic fluxs with upper magnetic cylinder lid 1, static iron core 2, dynamic iron core 3, magnetic guiding loop 5, magnetic cylinder 6, lower magnetic cylinder lid 7
Path, as shown in figure 4, wherein a paths are from the pole N of permanent magnetism 4, by magnetic guiding loop 5, dynamic iron core 3, static iron core 2, upper magnetic
Cylinder cap 1, magnetic cylinder 6 return to the pole S of permanent magnetism 4, generate upward magnetic force F1, another paths are from the pole N of permanent magnetism 4, by leading
Magnet ring 5, dynamic iron core 3, lower magnetic cylinder lid 7, magnetic cylinder 6 return to the pole S of permanent magnetism 4, generate downward magnetic force F2；Under gate-dividing state, move
Air gap between 2 lower end major-minor pole-face of 3 upper surface of iron core and static iron core is much smaller than 3 lower end surface of dynamic iron core and 7 upper end of lower magnetic cylinder lid
Air gap between major-minor pole-face, therefore F1 > F2, and overcome the elastic force F of switching-in spring 8NAnd vacuum interrupter generates self-closing power, makes
It obtains contactor and is maintained at releasing position；After coil 9 receives trigger signal, after energization with upper magnetic cylinder lid 1, static iron core 2, dynamic iron
Core 3, magnetic cylinder 6, lower magnetic cylinder lid 7 form magnetic flux path, and flow direction is as shown in Figure 5, this flow direction and permanent magnetism 4 pass through magnetic conduction
Ring 5, static iron core 2, upper magnetic cylinder lid 1, magnetic cylinder 6, returns to magnetic flux (generating the magnetic flux of magnetic force F1) side that permanent magnetism 4 generates at dynamic iron core 3
To on the contrary, being in counteracting trend, so that magnetic force F1 reduces；When the F1 of upward direction overcomes the first spring 8 in downward direction to generate bullet
Power FNAnd after the self-closing power of vacuum interrupter generation (or do not include the first spring 8 and generate elastic force FN, only vacuum interrupter is produced from
Close power), it is less than F2 in downward direction with joint efforts, then makes dynamic iron core 3 that pull rod 21, insulated part, moving contact 18 be driven to move downward,
At attracted position, feed motion is completed, after combined floodgate, the electric current in major loop is by quiet busbar 22, static contact 17, dynamic touching
First 18, moving conductive row 23 completes to connect return circuit；At closing position, as shown in figure 5, static iron core 2, dynamic iron core 3, permanent magnetism
4, magnetic guiding loop 5, magnetic cylinder 6, lower magnetic cylinder lid 7 form magnetic circuit, between 2 lower end surface major-minor pole-face of 3 upper surface of dynamic iron core and static iron core
Air gap is much larger than the air gap between 7 upper surface major-minor pole-face of 3 lower end surface of dynamic iron core and lower magnetic cylinder lid, therefore F1 < F2, and combined floodgate bullet
The elastic force F of spring 8NAnd the self-closing power direction of vacuum interrupter promotes to be attracted always, it is identical as the direction F2, therefore resultant force, so that contact
Device is maintained at closing position.
In the case of major loop goes wrong, in the case of above-mentioned triggered as normal signal enabling coil 9, contactor access failure,
Start immediately explosive, explosive 12 is ignited, and explosion generates stress and quickly pushes piston 10, and piston 10 drives pull rod 21, dynamic iron
Core 3, entire insulated part structure and moving contact 18 are moved to attracted position, complete contactor feed motion.
Novel permanent magnetic explosion hybrid contactor of the present invention is that the dual trigger Redundancy Design reliably closed a floodgate ensures that contactor exists
Major loop reliably closes a floodgate in the case of ging wrong；Pure explosive structure mostly destructiveness, only once disjunction, not reproducible use, this
The purer explosive structure of invention compares, contactor body construction can repeatedly be utilized by realizing, and reduces test and application process
The wasting of resources；Compared with pure electromagnetic type or magneto, explosive closing speed is fast, and the entire making process time is that us magnitude can
It completes, closing speed is fast, security performance is higher；Present invention incorporates electromagnetic type or magnetos and explosive advantage, realize
Rapid closing under repeatable division and special occasions, greatly improves cost performance
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
