" mountain " font intermediolateral column, it is connected simultaneously with two commutation diodes D1 and D2 positive and negative electrode by the lead b10 of coil 7, by 220v
Or 380v AC rectification is two semi-wave DCs, 12 and are switched by start button switch 13, stop button respectively
Change-over switch 14 is electrically connected to each other, and is formed the positive semi-wave DC of 7 one startups of input coil, is made the quilt of electromagnetic core 6
Magnetization produces an adhesive magnetic force opposite with the magnetic polarity of permanent magnetism iron core 4 and the reverse half-wave DC of adhesive and a stopping is electric
Flow, make electromagnetic core 6 produce another to repel magnetic force with the magnetic pole identical of permanent magnetism iron core 4 and discharge, forming moment in coil 7 leads to
No current, the noiseless job state powered off after electricity；
Commutation diode D1 and D2, using the pole of common rectification two more than IN400 is serial, pressure-resistant 400 volts and electric current 0.5 are pacified
Pipe；
Change-over switch 14, start button switch 13, stop button switch 12 and its electric connection mode, wherein：Change-over switch
14 include switch seesaw 22, electric bridge seesaw 21, switch a points 18, switch o points 19 and switch b points 20, are arranged on and elastic force tabletting 23
In the contactor housing of precision-fit；Start button switch 13 and stop button switch 12 possess normally opened touch using identical two
The compound button switch of point 15, normally-closed contact 17 and conductive bridge plate 16；
By the switch b points 20 of a normally-closed contact 17 and the change-over switch 14 of start button switch 13, another normally closed touches
Point 17 and a normally opened contact 15 of stop button switch 12, another normally opened contact 15 of stop button switch 12 and rectification two
Switch a points 18 of pole pipe D2 negative pole electrical connection and a normally opened contact 15 and the change-over switch 14 of start button switch 13, separately
One normally opened contact 15 and a normally-closed contact 17 of stop button switch 12, another normally-closed contact of stop button switch 12
17 electrically connect and the lead 10 of the one end of coil 7 draws with diode D1D2 both positive and negative polarities, the other end with commutation diode D1 positive pole
Line 9 electrically connects with a power line 11, another power line 11 with the switch o points 19 of change-over switch 14, composition press startup by
Button switch 13, the coil 7 on electromagnetic core 6 obtain a positive half-wave current opposite with the magnetic polarity of permanent magnetism iron core 4 and adhesive
And power off, after power-off, adhesive is continued by the magnetic attraction of permanent magnetism iron core 4 and presses stop button switching the 12, line on electromagnetic core 6
Circle 7 obtains another and discharges and power off with the reverse half-wave current of magnetic polarity identical of permanent magnetism iron core 4, after power-off, by counter-force bullet
The reverse support force of spring 5 continues for permanent magnetism iron core 4 to be suspended in the relational structure of the top of electromagnetic core 6, realizes coil 7 in operation
No current, noiseless energy-saving and environmental protection operation in journey.
In use, because before the use, permanent magnetism iron core 4 is supported with electromagnetic core 6 by reaction spring 5, in suspension shape
State, elastic force tabletting 23 is above the switch seesaw 22 of change-over switch 14, electric bridge seesaw 21 and switch a points in change-over switch 14
18th, o points 19 are switched to turn on；Press start button switch 13 moment, external AC power supply by a power line 11 from switch o
Point, switch a points, two normally opened contacts 15 of starting switch 13, two normally-closed contacts 17, commutation diodes of shutdown switch 12
Lead 10, coil 7, lead 9 and another power supply of a half-wave current and coil 7 after D1, rectified diode D1 rectifications
Line 11 forms loop, and the magnetic pole magnetization electromagnetic core 6 opposite with the magnetic polarity of permanent magnetism iron core 4 of moment formation one, makes in coil 7
Mutual attraction between electromagnetic core 6 and permanent magnetism iron core 4, it is sufficient to which the support force for resisting reaction spring 5 inhales lower permanent magnetism iron core 4, main
Contact 2 closes, and under suction while permanent magnetism iron core 4, elastic force tabletting 23 switchs a below the switch seesaw 22 of change-over switch 14
Point 18 disconnects with switch o points 19, and coil 7 loses loop power-off, at this moment because permanent magnetism iron core 4 is long-range to the suction of electromagnetic core 6
Continue to keep adhesive in the support force of reaction spring 5, main contacts 2 remains closed, and realizes the no current of coil 7, noiseless fortune
OK；During stopping, due to iron core adhesive, elastic force tabletting 23 is downward, and electric bridge seesaw 21 turns on switch b points 20, switch o points 19, presses
The moment of lower stop button switch 12, AC power is by another power line 11 from lead 9, coil 7, lead 10, the pole of rectification two
Pipe D2, two normally opened contacts 15 of shutdown switch 12, two normally-closed contacts 17 of starting switch 13, the switch b of change-over switch 14
Point, switch o points, power line 11 form loop, and coil 7 obtains the half-wave current of an opposite direction, and moment forms electromagnetic core 6 and produced
Life one is mutually exclusive with the magnetic polarity identical magnetic pole of permanent magnetism iron core 4 and discharges, and the release of permanent magnetism iron core 4 is returned to and is suspended at electricity
The top of magnetic core 6 is in situ, and while release permanent magnetism iron core 4 are repelled, elastic force tabletting 23 is pushed back to the top of switch seesaw 22, opens
Close b points 21 to disconnect with switch o points 19, coil 7 loses loop power-off, and at this moment permanent magnetism iron core 4 is due to by the support force of reaction spring 5
Support and continue to keep suspending with electromagnetic core 6, main contacts 2 maintains a normally open.
A kind of permanent-magnet energy-saving contactor of the present invention, by forming the change-over switch 14 of the contactor, start button switch 13, stopping
The only interrelated connection of button switch 12, commutation diode D1 and D2, two commutation diode D1 and D2 are formed by alternating current
Source rectification is two semi-wave DCs, two semi-wave DCs, when starting and stopping electricity consumption implementation, is opened by pressing
The moment of dynamic button switch 13, coil 7 produce electromagnetic core 6 be geomagnetic into the opposite pole of permanent magnetism iron core 4 and adhesive simultaneously
Continue to keep adhesive with electromagnetic core 6 by the magnetic attraction of permanent magnetism iron core 4 after power-off, power-off and press stop button switch 12
Moment, coil 7 produce electromagnetic core 6 like pole of permanent magnetism iron core 4 is ostracised discharge and power off, power off after due to anti-
The support force of power spring 5 and continue to keep the suspended state of permanent magnetism iron core 4, reaching operation operation that control electricity consumption implemented with stopping
While only, the energy-saving and environmental protection operation of the no current of coil 7, electromagnetic core 6 without electric and magnetic oscillation noise is realized, overcomes existing skill
Art will flow through current induced magnetic field all the time using coil, make the operation operating type of contact closure, consuming electric energy be present and have electricity
The defects of magnetic vibration noise, and simple in construction, raw material are common, processing and manufacturing is easily achieved, meanwhile, for the section in current generation
Energy emission reduction, optimizing the environment has practical realistic meaning, is worthy of popularization.
