Description
Technical field
The present invention relates to a kind of switchgear, have：Electromagnetic actuator device, the electromagnetic actuator device, which has, carries coil case
Coil, stationary positioned yoke and can relative to stationary positioned yoke move armature；And switch contact, the switch touch
The contact of point can be switched on and off by motion of the armature along axis.
Background technology
Such switchgear can be designed with DC magnet systems, wherein the side-walls in the inside of framework
Mounting permanent magnet, it magnetizes transverse to the moving direction of armature and direction is medially equipped with the cover plate being fabricated from iron.
The pole plate being connected with armature is arranged below the cover plate.The field wire of the strong boundling occurred at the narrow side of coverage rate passes through
Pole plate and framework close and cause armature together with pole plate by permanent magnet attraction.This magnetic being applied on armature is protected
Holding force can realize that reduction is typically subjected to the power of the back-moving spring of whole confining forces.Coordination each other must assure that enough
Impact strength, so that when switchgear, especially contactor will not be due to acceleration of gravity equivalent to such as twice
The shock of stress and trigger, i.e., unintentionally switch.Generally, in the contactor of no permanent magnet, impact strength is only led to
The spring force of back-moving spring is crossed to determine.
If the coil of DC magnet systems is energized, then the coil flowed through depending on electric current is higher by extremely more magnetic
Power, pole plate triggered together with armature by permanent magnet and it is mobile in the case where overcoming working gas gap until pole plate be resisted against it is anti-
At remanent magnetism plate.It is also referred to as due to the excitation to coil in this position of " on " position, such as at contact carrier
Contact contacted with fixed contact.
There is following demand in such switchgear, can always be connected in given structural volume bigger
Power.Therefore, it is necessary to higher contact force, now to control the turn-on current for becoming higher.Here, switching process must be
Realize, i.e., realized in default voltage in the whole default working range of magnet exciting coil.
In order in view of the contact force improved when more powerful, it is necessary to more strongly design electromagnetic actuator device.This causes
The connection energy that significantly improves simultaneously and then can be also noticeable with the switch noise of raising.Such as the application in switchgear
In, switch noise can be interfering.
The reduction of switch noise by means of electronic circuit for example by reducing on voltage to realize.Electronic circuit can connect
It is connected between control supply voltage and the coil of electromagnetic actuator device.For ON switch equipment, only by so-called low pressure, i.e. most
Low permission is applied supply voltage on coil.Once the contact closure of switch contact, then improve voltage, so that it is guaranteed that needing
High contact force.The shortcomings that this measure, is, the turn-on time of switchgear is increased in a manner of unfavorable.
The content of the invention
Correspondingly, it is an object of the present invention to a kind of switchgear for the switch noise for having and reducing be proposed, without not
Closing speed is influenceed sharply.
According to the present invention, the purpose realizes have by a kind of switchgear：Electromagnetic actuator device, electromagnetic drive dress
Put with the coil of coil case, the yoke of stationary positioned and the armature that can be moved relative to the yoke of stationary positioned；And
Switch contact, its contact can be switched on and off by motion of the armature along axis.Here, it is a feature of the present invention that
Floating ground is supported with inner yoke at coil case.
The core of the present invention is that the inner yoke being rigidly fixed up to now is driven preferably together with permanent magnet in magnetic
Floating twelve Earthly Branches are held on the moving direction of dynamic device.By this floating support, reduce it is from switch contact, from pole plate transmission
Energy on to inner yoke.Because the Impact energy is captured by the arrangement of the floating, equally reduces and now occur
Noise.The switch noise of magnet system is reduced herein.
It can be proposed in particularly advantageous design, permanent magnet is supported with inner yoke, this is forever
Long magnet follows inner yoke to move, so to capture the energy of mobile part and thus to reduce switch noise.Forever
Therefore also floating ground supports magnet.In the switching process being delivered to from pole plate in inner yoke, supporting that energy passes through the floating
To weaken.Impact energy is absorbed by the arrangement of floating, so as to reduce the noise now occurred.
There can be other scheme in the special design of the present invention, at coil case, in the upper of inner yoke
Side is disposed with gap, to expand the moving range of inner yoke.Gap at coil case can construct particularly by milling.It is interior
Thus yoke is no longer rigidly fixed between coil case and pole plate, but have certain moving range.
It can be proposed according to the present invention, switchgear is contactor.
It is furthermore possible to propose, contactor has DC magnet systems.
The magnetic for coil with coil case is had according to the electromagnetic actuator device of the switchgear of the present invention, being fixedly positioned
Yoke, and the armature that can be moved relative to the yoke of fixed positioning, yoke are surrounded coil and preferably can supported to damping
In the housing of switchgear, armature connected coil and had pole plate with following above coil.Arranged at coil
There is the inner yoke that floating ground supports.Permanent magnet is disposed between inner yoke and yoke, it preferably floats together with inner yoke
Ground is supported and has certain moving range, and the moving range is constructed by the gap at coil case.At coil case
Gap directly formed herein by inner yoke.
It is a feature of the present invention that there is the factory side for being used for minimizing switch noise according to the switchgear of the present invention
The solution in face, and the turn-on time of switchgear will not be increased herein.Here, pass through factory solution party presented here
Case, customer need not use distinctive measure.Reduce switch noise element be configured to equipment it is intrinsic and can go to tool
On the complete structural series for having direct current magnet drive device.Further describe the present invention's below according to embodiment and accompanying drawing
Additional advantage and improvement scheme.
