Description

A kind of intelligent electromagnetism accuracy controlling formula motor electricity saving device

Technical field

The utility model relates to the electromagnetism debugging apparatus, especially a kind of intelligent electromagnetism accuracy controlling formula motor electricity saving device.

Background technology

At present, the course of work of existing high-efficiency and energy-saving type relay and contactor is as follows: relay and contactor are fed specified voltage and current, relay and contactor adhesive, main contacts is connected and is started working, because: to calutron, in the moment of relay and contactor energising, magnetizing coil produces the effect that magnetizes to its place iron core, after magnetizing coil removed electricity, iron core remanent magnetism was kept attracting state; To electromechanical assembly, mechanical mechanism is kept attracting state with sound iron core locking.In the process of keeping relay or contactor work, can cancel keeping voltage and keeping electric current, relay or contactor continue to remain under the operating state, after receiving release signal, the main contacts of relay or contactor discharges, and a duty cycle finishes like this.

Mainly there are following problem in existing high-efficiency and energy-saving type relay and contactor:

1, the iron core magnetizing time is long, produces adhesive and postpones;

2, long for solving the iron core magnetizing time, must select the medium ferromagnetic material of B-H loop for use, but produce the situation of keeping adhesive magnetic force deficiency, as can keeping adhesive reluctantly, but the acceleration that does not reach the GB regulation impacts;

3, since magnetic hysteresis loop to show the remanent magnetism of ferromagnetic material bigger, the energy that oppositely magnetizes when forcing relay or contactor to discharge rises, and the control difficulty, is easy to generate overshoot and deficiency, causes relay or contactor not to discharge;

4, for making control accurately, must cause the circuit debugging difficulty to strengthen, the homogeneity variation between the product, cost rises;

5, general ferromagnetic metal sheet material is not examined magnetization property, be not used in the ferromagnetic metal sheet material of electrician's purposes under the normal condition, therefore the magnetic hysteresis loop of every batch of sheet material all is not quite similar, and workload strengthens when causing ordinary production, and the homogeneity between product is criticized and criticized is bad;

6, the energy that oppositely magnetizes when forcing relay or contactor to discharge rises, energy lengthening settling time, must increase the release time of relay or contactor, especially when overshoot, may cause the moment concussion of relay or contactor, have a strong impact on the release performance of relay or contactor product;

7, postpone by adhesive and the hangover causes the action frequency of relay and contactor to descend, magnetize repeatedly, demagnetizing causes degradation under the iron core heating magnetic property;

8, the size of remanent magnetism is kept the suction-combining force and is in no control state by the adhesive voltage decision of moment, can't guarantee the adhesive quality;

9, cause mechanical failure easily.

In view of the foregoing, existing high-efficiency and energy-saving type relay and contactor need to improve.

The utility model content

The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of intelligent electromagnetism accuracy controlling formula motor electricity saving device is provided, the suction-combining force deficiency is kept in solution, and magnetic property descended when iron core magnetized repeatedly, overshoot and deficiency when adhesive and hangover and demagnetization; Improve sucting speed and quality, avoid mechanical failure.

The utility model adopts following technical scheme to achieve these goals: a kind of intelligent electromagnetism accuracy controlling formula motor electricity saving device is by E type moving iron core, E type secured core, and spring, slide rail, coil constitutes; Horizontally set E type moving iron core between the slide rail of two vertical symmetries, the groove of E type moving iron core is downward; The below correspondence of E type moving iron core is provided with E type secured core, and the groove of E type secured core upwards; Between E type moving iron core and the E type secured core spring is set; In the groove of E type secured core coil is set.

Operation principle of the present utility model is: make iron core with retentive material and soft magnetic material, the retentive material iron core is by pre-magnetizing, when leading to forward voltage, coil on the soft magnetic material iron core, produces the magnetic field opposite with the retentive material iron core, because opposite pole is inhaled mutually, iron core overcomes flexible member under the effect of magnetic field force strength attracts each other, moves to the formation closed magnetic circuit, coil blackout is kept attracting state by closed magnetic circuit.Produce the magnetic field identical with the retentive material iron core when coil leads to reverse voltage on the soft magnetic material iron core, because like pole repels each other, iron core separates under the effect of magnetic field force and flexible member, and coil blackout is kept release condition by flexible member.

When initial state was soft magnetic material iron core and the driving fit of retentive material iron core, the earlier logical reverse voltage of coil made its release; The logical forward voltage in back makes its adhesive; Course of action is opposite with said process.

The beneficial effects of the utility model are: simple in structure, transform easily, and the work frequency of relay and contactor is effectively improved, whole power consumption reduces, and magnetic loss is little, heating is low; Easy to use, with low cost, be convenient to promote.
