Description
Technical field
The present invention relates to permanent magnet mechanism, especially relates to a kind of switch self-closing magnetic circuit permanent magnetic mechanism.
Background technology
As the parts of permanent magnet mechanism are few, life-span length, with divide-shut brake stable action time, acting characteristic is controlled, and
The features such as easily realizing quick disjunction, is favored by user.But the moving component of permanent magnet mechanism is in motor process, by permanent
The comprehensive function of Magnet and coil magnetic field, especially at the initial stage of separating brake, the magnetic field that permanent magnet is produced is to its separating brake athletic meeting
Play a part of obstruction, cause the just-off speed for switching to be difficult to improve, and the just-off speed for switching is weighed for drop-out current very much
Will, therefore, the opening characteristic of permanent magnet mechanism should not meet the requirement of switch, especially for voltage levels or to opening characteristic
Require higher product, it more difficult to meet demand.
The permanent magnet mechanism for now commonly using, its iron core is in closing position, and permanent magnet is placed in middle yoke, works as switch
Carry out during separating brake (i.e. just stage by stage), switching winding is powered, the magnetic line of force is produced, be i.e. the magnetic field force of switching winding generation receives iron core
Power is downward, realizes separating brake action.But simultaneously, the magnetic field magnetic line direction that permanent magnet is produced is that magnetic field force makes iron core stress
Upwards, power plays a part of obstruction towards combined floodgate direction to separating brake in direction.When iron core moves past the half of stroke, forever
The magnetic field force that Magnet is produced is just consistent with separating brake motion.During switch separating brake, it is desirable to have certain just-off speed, permanent magnet is dividing
Lock the second half plays a part of promotion, has had already passed by the critical stage that firm timesharing improves opening velocity.
Chinese patent CN 201465818U adopts multipath magnetic circuit fracture mode, during switch just divides, using multi-break side
Formula, quick increase permanent magnet magnetic circuit magnetic resistance, retroaction of the permanent magnet to separating brake during just dividing is overcome, is solved and join
The low problem of permanent magnetic actuator vacuum switch opening velocity, but when this structure has closing position, the closing coil magnetic line of force is with forever
Long Magnet magnetic line of force part inverse problem.
Content of the invention
Present invention seek to address that joining the problem that permanent magnetic mechanism switch opening velocity is difficult to improve, providing and can slacken permanent magnet
Raising to opening velocity during just dividing produces reaction effect, and the one kind for effectively improving high-voltage switch gear just-off speed is opened
Pass self-closing magnetic circuit permanent magnetic mechanism.
The present invention is provided with drive rod, combined floodgate side yoke, permanent magnet, dynamic iron core, closing coil, outer tube yoke, middle magnetic
Yoke, switching winding, separating brake side yoke；Combined floodgate side yoke and separating brake side yoke be respectively arranged on outer tube yoke top and under
Portion, dynamic iron core be located between combined floodgate side yoke and separating brake side yoke, drive rod from top to bottom through combined floodgate side yoke, dynamic iron core and
Separating brake side yoke, closing coil and switching winding are located between combined floodgate side yoke and separating brake side yoke from top to bottom, middle yoke
Between closing coil and switching winding, permanent magnet is placed in the yoke permanent magnet of combined floodgate side, and one end of permanent magnet sets
There is air gap.
The width of the air gap can be 1～5mm, and the air gap can be filled using nonmagnetic substance.The acting as of the air gap：
When separating brake is switched, dynamic iron core leave the distance of closing position, i.e. dynamic iron core and combined floodgate side yoke more than air gap width when, by
Increase in the magnetic resistance of dynamic iron core main magnetic circuit, make the magnetic line of force self-closing of permanent magnet, the most or part of the magnetic line of force of permanent magnet
By small air gap short circuit, no longer pass through dynamic iron core main magnetic circuit, it is to avoid the magnetic field that permanent magnet is produced is hindered to separating brake motion, is reached
The purpose for accelerating just-off speed is arrived.
One end of the permanent magnet can be upper end or the lower end of permanent magnet.
Middle yoke of the present invention between closing coil and switching winding, through the drive rod of dynamic iron core.Permanent magnet
It is placed in the yoke of combined floodgate side, permanent magnet mechanism one end (upper end or lower end) has a small air gap (or filling using nonmagnetic substance), when
During switch separating brake, dynamic iron core is at a distance from rear, and permanent magnet will produce self-closing type magnetic circuit, and magnetic circuit short circuit is not being led
The power for hindering dynamic iron core separating brake is produced in magnetic circuit, is conducive to improving the just-off speed of switch.The present invention can also adopt unicoil mould
Formula permanent magnet mechanism, when using unicoil pattern permanent magnet mechanism, closing coil and switching winding share a coil, positive logical
Stream, realizes closing a floodgate, is reversely energized, realizes sub-switching operation.
