Description
What the present invention relates to is a kind of non-noise AC contactor with very-low energy consumption
The A.C. contactor of existing various series, because it adopts E type or U sections core to power up the contact power of magnetic zygonema circle start fixed contact, thereby as long as A.C. contactor work, the electromagnetism pull-in winding just has electric current to pass through, it must consume certain electric energy, and along with the difference of the big low capacity of A.C. contactor, its pull-in winding consumes energy from little several watts (VA) to several hectowatts (VA), so just there is the electric energy of hundreds of hundred million degree (during KVA/) every year in the whole nation by invisible slatterning, and can produce noise and thermal pollution environment.
The objective of the invention is defective, propose a kind of non-noise AC contactor with very-low energy consumption at above-mentioned existence.
Technical solution of the present invention: include E type (or U type) iron core, centre at the upper and lower iron core 2,3 of E type (or U type) is provided with electromagnetism pull-in winding 4, movable suction disc 5 fuses with the upper and lower iron core 2,3 of movable E type (or U type), pole shoe 6 holds suction disc 5, establish permanent magnet 8 in the centre of left and right sides pole shoe 6, be provided with bucking coil 7 on the top of pole shoe 6, bucking coil 7 connects capacitor discharger 11, one side of electromagnetism pull-in winding 4 is established cut spring 9

Advantage of the present invention:
(1) this A.C. contactor only needs instantaneous energising from being disconnected to connection working electromagnet pull-in winding, is not subjected to the influence of voltage ripple of power network, thereby has improved the useful life of electromagnetism pull-in winding.
(2) during this A.C. contactor operate as normal, the contact power of moving, fixed contact, suction from permanent magnet magnetic field, this tries hard to keep and holds the life-span that weighing apparatus helps improving moving fixed contact surely, the electromagnetism pull-in winding need not be switched on simultaneously, therefore save a large amount of electric energy, realized not having hot, noiseless, operation, environment purification.
(3) reduce inductive loads in the electrical network in a large number, thereby improved the power factor (PF) of power supply network.
(4) also possess the repertoire of existing A.C. contactor, and compact conformation, the longevity used
Life is long etc.
Accompanying drawing 1,2 is respectively structural representation of the present invention, cut-away view.10 is pedestals among the figure, the 1st, and the moving contact skeleton
Accompanying drawing 3 is electrical schematic diagrams of capacitor discharger.
Below in conjunction with accompanying drawing operation principle of the present invention is described.
(1) press knob down switch QA power supply and lead to, electromagnetism pull-in winding 4 moments energising generation suction drive suction disc 5 moves downward by pole shoe 6 and sucks, release button switch QA, and A.C. contactor enters operating state, realizes no energy consumption, silent running.
By electrical schematic diagram electromagnetism pull-in winding 4 energisings as can be known, its auxiliary relay contact CJ

3Obtain trigger voltage and be in conducting state, just by bucking coil 7 discharges, its discharging current produces and permanent magnet 8 opposite polarity magnetic fields capacitor C1, makes pole shoe 6 tops magnetic altogether, and suction disc 5 is released A.C. contactor and quits work.
(3) chain control: this A.C. contactor possesses the usefulness of the input interface of normally-open normally-close contact for chain control.
With the capacitor discharger that above element is formed, perhaps form the capacitor discharger of said function with the flexible replacement of relay controllable silicon.
This patent is little energy consumption, and though several years power consumption of amount of capacity continuous operation less than 4 kilowatts/time, i.e. 4 degree electricity, energy-saving effect is considerable, noiseless during work, long service life simple in structurely is easy to establishment.
