Description
Technical field
The present invention relates to power domain, in particular it relates to the catalyst of low eddy-current loss.
Background technology
Catalyst, mainly in order to control direct circuit, is only that power supply plays transmission effect, electrical appliance size and electrical appliance
Rated current is relevant.In the catalyst of present use, when being connected with alternating current in coil, the magnetic flux produced in iron core is
With the change of electric current same frequency, when power frequency is 50Hz, magnetic flux is per second has 100 times through zero crossing.When magnetic flux is through zero time,
Suction produced by it is also zero, and dynamic unshakable in one's determination (armature) leaves trend, but not and leave, magnetic flux does not the most quickly rise, dynamic iron core
The most sucked back, result causes vibration, produces noise, reduces the service life of catalyst, and produces eddy-current loss.And eddy-current loss
It is conductor when moving in non-uniform magnetic-field or be in time dependent magnetic field, the energy that the electric current inducted in conductor causes
Amount loss, needs to avoid in transmittance process, to increase effective utilization of electric energy.
Summary of the invention
The technical problem to be solved is to provide the catalyst of low eddy-current loss, and this apparatus structure is simple, passes through
The iron core of special setting, utilizes divided magnetic ring can allow between iron core the magnetic flux by two different casees in time, makes the total magnetic flux will not
Exceed zero point, reduce noise, reduce eddy-current loss, improve service life.
The present invention solves the problems referred to above and be the technical scheme is that the catalyst of low eddy-current loss, including moving contact, electricity
Sense coil, rotation bar, iron core, static contact, mounting seat, horizontal cross bar and base plate, described inductance coil, mounting seat and level are horizontal
Bar is all vertically mounted on base plate, and inductance coil, between mounting seat and horizontal cross bar, is also pacified on the end face of inductance coil
Dress iron core, iron core is formed by polylith silicon steel sheet stack riveting, equipped with divided magnetic ring on end face unshakable in one's determination, mounting seat is installed stationary contact
Head；Described rotation bar one end fixed installation moving contact, the other end is flexibly connected horizontal cross bar, also installs on the surface rotating bar
Armature, armature is relative with iron core, is respectively provided with terminals on the lower section rotating bar and mounting seat；Described moving contact and static contact
Relatively.Iron core is divided into two parts, bottom unshakable in one's determination not to be wrapped by divided magnetic ring, by the magnetic flux of this part by divided magnetic ringProduce
Suction, the upper surface unshakable in one's determination that divided magnetic ring is wrapped produces induced potential and electric current in divided magnetic ring, magnetic produced by this electric current
Lead to and will attempt to stop the change of magnetic flux in upper surface, cause the actual magnetic flux through upper surfaceLag behindOne angle, ferrum
Suction produced by the upper surface of the heartAlso will be late by, make total making a concerted effortF Without zero point, thus eliminate vibration and
Noise, decreases eddy-current loss, and vibrations unshakable in one's determination reduce, improve service life.This device only need to access electricity inductance coil
Source, can produce electromagnetic induction and make iron core hold armature, so that moving contact contacts with static contact, switch on power, then will need
The electrical equipment accessed connects terminals, can realize electrical equipment and connect electricity, and simple in construction is easy to use.
Described iron core is divided into two-layer, two-layer to stagger, and every layer is vertically stacked by polylith stalloy and to rivet together, only on top
Equipped with divided magnetic ring on Ceng.Two-layer staggers, and upper strata magnetic flux and lower floor magnetic flux can preferably work alone, and are independent of each other, and unshakable in one's determination is upper
When layer can preferably realize the stenosed section that magnetic flux passes thin slice, some narrow and small loops stream that eddy current is limited in each
Crossing, and the clean electromotive force in these loops is less, the length in loop is relatively big, then owing to the resistivity of this sheeting is big, this
Sample just can significantly reduce eddy-current loss.
It is also connected with antagonistic spring between bottom described rotation bar and bottom base plate.When after inductance coil power-off, unshakable in one's determination and
Armature separates, pullling because of spring, it is to avoid rotates bar and 360 ° of rotations occurs, cause security incident, damages and rotate on bar
Moving contact and rotate the active connection place of bar and horizontal cross bar, improve service life.When unshakable in one's determination and armature need adhesive
Time, antagonistic spring can be compressed again, does not affect its adhesive, flexible and convenient to use.
Described moving contact and static contact opposite end are arcuate structure.It is easy to preferably contact.
The angular range that the flexible connection point that described rotation bar can be wound on horizontal cross bar rotates counterclockwise is 0-45 °.
While ensureing iron core and armature adhesive and separating, moreover it is possible to avoid rotating bar rotation amplitude excessive, it is ensured that the safety of each parts.
Two terminals are also set up on described inductance coil.Convenient and outside electric equipment is connected.
To sum up, the invention has the beneficial effects as follows:
1, the present invention iron core by special setting, utilizes divided magnetic ring can allow between iron core the magnetic by two different casees in time
Logical, make total magnetic flux not over zero point, reduce noise, reduce eddy-current loss, improve service life, this apparatus structure is simple, real
With convenient.
2, two-layer unshakable in one's determination staggers, and upper strata magnetic flux and lower floor magnetic flux can preferably work alone, and are independent of each other, the upper strata of iron core
When can preferably realize the stenosed section that magnetic flux passes thin slice, some narrow and small loops that eddy current is limited in each are flow through,
And clean electromotive force in these loops is less, the length in loop is relatively big, then owing to the resistivity of this sheeting is big, thus
Eddy-current loss can be significantly reduced.
3, the setting of antagonistic spring, when, after inductance coil power-off, iron core separates with armature, drawing because of spring
Pull, it is to avoid rotate bar and 360 ° of rotations occur, cause security incident, damage the moving contact rotated on bar and rotation bar is horizontal with level
The active connection place of bar, improves service life.
