Description
Technical field
The present invention relates to a kind of main drive circuit of bistable state permanent magnet operating mechanism, overcome big stroke forever particularly to one
Magnetic operating mechanism divides, combined floodgate pick-up current is excessive and just-off speed is unsatisfactory for the main drive circuit of permanent-magnet operating mechanism that requires.
Background technology
Generally when designing permanent-magnet operating mechanism, it is considered that: when dynamic iron core is at open position, if requiring to close a floodgate,
In closing coil, then pass to appropriately sized and direction electric current, this electric current dynamic iron core in open position side and separating brake side end cap
Between air gap in produced magnetic field can cancel each other with by magnetic field produced by permanent magnet, this electric current is at dynamic iron core and combined floodgate
In air gap between side end cap, produced magnetic field then produces the driving force driving dynamic iron core to move to closing position；When dynamic iron core
When closing position, if requiring separating brake, then passing to appropriately sized and direction electric current in switching winding, this electric current is closing a floodgate
In air gap between dynamic iron core and the combined floodgate side end cap of side, position, produced magnetic field can be mutual with by magnetic field produced by permanent magnet
Offseting, in this electric current air gap between dynamic iron core and separating brake side end cap, produced magnetic field then produces the dynamic iron core of driving to dividing
The driving force that gate position moves.But, when actuator travel is longer, and analysis shows, use common twin coil bistable permanent magnetic to grasp
Make mechanism design method, either close a floodgate or separating brake, depend merely on magnetic field produced by the magnetizing coil of side and to drive dynamic iron core dynamic
Make, required magnetomotive force is the biggest, beyond design on accept scope.
Summary of the invention
The invention provides a kind of can the main drive circuit of bistable state permanent magnet operating mechanism of quick release, solve big stroke
Permanent-magnet operating mechanism divides, combined floodgate pick-up current is excessive and just-off speed be unsatisfactory for require technical problem.
The present invention is to solve above technical problem by the following technical programs: switching winding and closing coil are joined by imagination
Close and use (series connection): when dynamic iron core is at closing position, as wanted separating brake, closing coil produce and offset permanent magnet in the generation of combined floodgate side
The magnetomotive force in magnetic field, and common in the air gap between dynamic iron core and separating brake side end cap by switching winding magnetomotive force and permanent magnet
Excitation field produces the driving force making iron core carry out separating brake action；When dynamic iron core is at open position, as closed a floodgate, by separating brake line
Circle produces offsets the magnetomotive force in magnetic field that permanent magnet produces in separating brake side, and by closing coil magnetomotive force and permanent magnet at dynamic iron core
And common activation magnetic field produces the driving force making iron core carry out feed motion in the air gap between combined floodgate side end cap.Analytical calculation
Show, during separating brake, when air gap between dynamic iron core and combined floodgate side end cap is less, along with being gradually increased of separating brake exciting curent,
The direction of dynamic stress unshakable in one's determination presents the variation tendency in " combined floodgate direction-separating brake direction-combined floodgate direction ", and reason is as separating brake and swashs
Being gradually increased of magnetoelectricity stream, in the air gap between dynamic iron core and combined floodgate side end cap, the magnetic field that the magnetomotive force of closing coil produces
After offsetting the magnetic field that permanent magnet produces gradually superfluous, and owing to the air gap between dynamic iron core and combined floodgate side end cap is less, this mistake
Residual magnetic field is relatively strong, and the power being crossed the combined floodgate direction that residual magnetic field produces by this that dynamic iron core is subject to reaches certain value at separating brake exciting curent
After will exceed air gap between dynamic iron core and separating brake side end cap of switching winding magnetomotive force and permanent magnet (at this moment dynamic unshakable in one's determination and separating brake
Air gap between side end cap is bigger) in the common magnetic field the produced size to the power in the separating brake direction of dynamic iron core, make unshakable in one's determination always
Impact direction be combined floodgate direction；During combined floodgate, also there will be similar phenomenon, i.e. air gap between dynamic iron core and separating brake side end cap
Time less, along with being gradually increased of combined floodgate exciting curent, dynamic Impact direction unshakable in one's determination presents " separating brake direction-combined floodgate direction-separating brake
Direction " variation tendency.Visible, directly switching winding and closing coil are connected as separating brake magnetizing coil or the excitatory line that closes a floodgate
It is undesirable that circle uses.
Propose a kind of can the bistable state permanent magnet operating mechanism method for designing of quick release: during separating brake, only use combined floodgate side
A part (connecting with separating brake lateral coil) for coil is as separating brake trip coil, and magnetic field produced by its magnetomotive force is used for offsetting forever
The magnetic field that magnet produces in air gap between dynamic iron core and combined floodgate side end cap；During combined floodgate, only use a part for separating brake lateral coil
(connecting with combined floodgate lateral coil), as combined floodgate trip coil, magnetic field produced by its magnetomotive force is used for offsetting permanent magnet at dynamic iron core
And the magnetic field produced in air gap between separating brake side end cap.It should be noted that the turn ratio of trip coil and main driving coil is wanted
An appropriate numerical value is determined through computational analysis.Compare through repeatedly calculating, it is believed that trip coil and the circle of main driving coil
Number ratio can be using 1/3 as reference.The permanent-magnet operating mechanism being used in vacuum circuit breaker based on the method design not only solves
Along with exciting curent increases dynamic iron core Impact direction, problem repeatedly, required point, combined floodgate initiating electricity occur during aforementioned divide-shut brake
Stream is also greatly reduced, and other performances meet concerned countries standard-required the most very well.
