In addition, in the present invention, the mover 5 and push rod 6 can be under the different working conditions of D.C. contactor
Keep the principle of equilibrium state are as follows:
1) D.C. contactor is under off working state (release conditions):
Coil no power under this state, first permanent magnet 8 and 9 same polarity of the second permanent magnet are repelled each other, between the two
Generate the upward repulsion F of an Impact directionReprimand 1；Moving component (contains the moving contacting plate 3, mover 5, push rod 6, reset spring at this time
7, the first permanent magnet 8, mounting blocks 10, touch spring 12, bearing plate 13, magnetic guiding loop 15) total force be that G, Impact direction are downward；
The reset spring 7 is in compressive state, with the counter-force F that an Impact direction is downwardAnti- 1.So in this case, FReprimand 1=G+
FAnti- 1, therefore, moving component keeps force balance state, and the stationary contact 2 and moving contacting plate 3 of D.C. contactor are disconnected, kept out
Road.
2) under D.C. contactor is in running order:
2a) D.C. contactor is under dynamic behavior:
When coil is initially powered up, magnetic field is generated in magnetic circuit, and generate electricity in attached magnetic circuit the first gap d1 shown in Fig. 4
Magnetic attraction (magnetic circuit the first gap d1 magnetic pole is different), moving component overcomes gravity, spring force under electromagnetic attraction effect at this time
It moves upwards；
When moving component continues upward and moves to magnetic circuit lower part and the second gap d2 occur, then just shown in the attached drawing 5
Magnetic circuit the second gap d2 generates electromagnetic attraction (magnetic circuit the second gap d2 magnetic pole is different), and moving component will be in electromagnetism at this time
It is moved downward under suction and gravity.
2b) D.C. contactor is under steady-working state:
By above-mentioned dynamic duty process, D.C. contactor finally reaches balance under attached state shown in fig. 6, at this time magnetic
Road closure, the stationary contact 2 and moving contacting plate 3 of D.C. contactor be in contact, and D.C. contactor is in steady-working state, and this
When, the upward repulsion F of an Impact direction is generated between first permanent magnet 8 and second permanent magnet 9Reprimand 2；The reset bullet
The counter-force F that spring 7 has an Impact direction downwardAnti- 2；The counter-force F that the touch spring 12 has an Impact direction downwardAnti- 3；Movement
The total force of component is G, Impact direction is downward；Magnetic circuit keeps electromagnetic attraction FInhale 1Impact direction it is upward；So in this state
Under, FReprimand 2+FInhale 1=FAnti- 2+FAnti- 3+ G, therefore, moving component keep force balance state, and D.C. contactor keeps access.
In conclusion the utility model is improved by structure, the job stability of D.C. contactor was both greatly improved, also
Product noise is effectively reduced, and reduces the power consumption of coil.
The above is only the preferred embodiment of the utility model, but is not intended to limit the utility model, and should refer to
It out, for those skilled in the art, without deviating from the technical principle of the utility model, can be with
Several improvements and modifications are made, these improvements and modifications also should be regarded as within the protection scope of the present utility model.
