Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figures 1-4, a kind of Self-recover overvoltage-undervoltage protection structure, it includes：Moving contact 1, moving contact rack 2, quiet iron
Core 1, coil rack 1, DC coil 1, DC coil 26, compression spring 1, static iron core 28, yoke 9, coil rack two
10th, magnetic conduction sheet 11, compression spring 2 12, dynamic iron core 13, Zola's spring 14, right tension spring 15.1 plate-like structure of moving contact, its one end are located at
In groove on moving contact rack 2, and it is flexibly connected with the groove on moving contact rack 2, the other end connects with the activity of dynamic iron core 13
Connect.Static iron core 1, static iron core 28 are engaged with yoke 9, and split forms rectangular configuration.Coil rack 1, coil rack 2 10
It is fixed in the rectangular configuration that static iron core 1, static iron core 28 and 9 split of yoke are formed.DC coil 1, DC coil 26
It is set in coil rack 1, the excircle of coil rack 2 10.Magnetic conduction sheet 11 is installed on coil rack 1, coil rack
In the middle part of 2 10 radial direction.Dynamic iron core 13 is in I-shaped column structure, and its one end is located in the kidney slot of moving contact 1 and can be in groove
Slide, the other end is located at coil rack 1, the inner cavity of coil rack 2 10, and can be in coil rack 1, coil rack 2 10
Inner cavity slide.Coil rack 1, coil rack 2 10 and dynamic iron core 13 are kept on the same axis.Compression spring 1, compression spring two
12 respectively positioned at static iron core 1, the inner cavity of static iron core 28, and can be slided in its corresponding inner cavity；Compression spring 2 12 is sleeved on dynamic at the same time
The major part end of iron core 13.Zola's spring 14, right tension spring 15 are respectively positioned on moving contact rack 2, are symmetrically arranged at moving contact 1
Opposite sides.
The present invention operation principle be：When circuit occurs over-pressed or under-voltage, DC coil 26 does not work, AC line
The energization conducting of one 5 moments is enclosed, the magnetic field suction dynamic iron core 13 of generation, dynamic iron core 13 moves right compression press spring 2 12 and static contact
Clap and close, and promote moving contact 1, be allowed on moving contact rack 2 rotate by a certain angle counterclockwise around " spring is crossed at dead point ", and make
Spring（Tension spring）Dead point is crossed, is eventually held in " off-state ", dynamic iron core 13 is returned to original by 2 12 reverse elastic force of compression spring at this time
Position.When line voltage distribution recovers normal, DC coil 1 does not work, and 26 moment of DC coil, which is powered, to be turned on, the magnetic of generation
Attract dynamic iron core 13, dynamic iron core 13 to the left clap and close by motion compresses compression spring 1 and static contact, and pulls contact 1, is allowed to touch dynamic
Certain angle is rotated clockwise around " spring is crossed at dead point " on head bracket 2, and makes spring（Tension spring）Dead point is crossed, is eventually held in
" closure state ", at this time dynamic iron core 13 returned to home position by one 7 reverse elastic force of compression spring.If things go on like this, when again circuit occurred
When pressing or is under-voltage and recovering normal voltage, the above process understands repetitive operation again, realizes that Self-recover overvoltage-undervoltage is protected.
The key technology point of Self-recover overvoltage-undervoltage protection structure of the present invention：
（1）Movable contact system：Control moving contact to be rotated on moving contact rack by tension spring, stent, tension spring and dynamic touch
Cooperation between head will be designed to very well, and just making moving contact, tension spring crosses dead point smoothly in closed and disconnected.Moving contact
To be designed at extension tension spring symmetrical so that contact side-to-side movement stress balance on stent, movement are reliable.
（2）Excitation system：Two coils and dynamic iron core will be kept on the same axis, so just can guarantee that dynamic iron core can be
Can smoothly it move along a straight line back and forth on two coil racks.Magnetic conduction sheet is added between coil so that during each coil working
There can be shorter field circuit, increase electromagnetic attraction.
Self-recover overvoltage-undervoltage of the present invention protects structure as double DC coil excitations, i.e. two identical absolute coils,
Coil is selectively turned on when under-voltage, over-pressed and voltage recovers normal, produces magnetic field, is driven dynamic iron core, is allowed to drive moving contact
Closure disconnects.Situations such as structure contactor gap is sufficiently large, will not produce electric breakdown, contact melted, and contact pressure
I is realized adjustable by varying extension spring structure greatly, and possesses certain breaking capacity, can avoid the appearance of failure problems.
