Description

A kind of economize on electricity magnetic

Technical field:

The present invention relates to a kind of attracting device, particularly a kind of magnetic.

Background technology:

Existing large-scale magnetic (as large-scale contactor magnetic), its iron core generally forms with silicon steel sheet is superimposed, when needing adhesive, coil must be switched on, like this, not only want consume electric power, produce magnetic loss, and, easily produce the magnetic shake between silicon steel sheet, the magnetic temperature raises, the environment around both having affected, and, if can not in time dispel the heat, can affect the normal use of magnetic.

In order to address the above problem, it is 200610036430.4 patented technology that the inventor has invented the patent No., by adopting the capacitor C charging rear oppositely to coil power supply, like this, the iron core that just can adopt the cast iron that easily is magnetized or irony iron core to be used as magnetic uses, so that iron core just need not to power to coil after being magnetized armature being held again, like this, just realized little power consumption, do not generated heat, without magnetic loss, can not produce the purpose of magnetic shake.But, oppositely give the electric weight of coil power supply accurate after the charging of this kind Technology Need capacitor C, in order to effectively eliminate magnetic force unshakable in one's determination, this will electronic component steady quality, and, guarantee that electronic component can not be subjected to extraneous interference, like this, brought certain inconvenience just for production and the use of circuit; In addition, cast core material and determined, because the material carbon containing is high, cause being not easy accurately according to the shape moulding that designs.

Summary of the invention:

Goal of the invention of the present invention be to provide a kind of economize on electricity, production and economize on electricity magnetic easy to use and reliable, the easy moulding of core configuration.

the present invention is achieved in that and comprises the iron core that consists of contactor, be wound around the coil of iron core, armature, be positioned at armature, spring between iron core, its special feature are that the material of iron core is phosphorus content less than 0.1% iron, connect a magnetic control circuit on coil, and the magnetic control circuit comprises normal open switch, the normally closed switch that is connected with power supply, normally opened contact in contactor, transformer or electric capacity, rectification circuit, normally closed switch one tunnel passes through normal open switch successively, rectification circuit and coil wherein an end are connected, and relay switch is passed through on normally closed switch another road successively, electric capacity or transformer, rectification circuit and coil wherein an end are connected or the magnetic control circuit comprises normally opened contact in contactor, transformer or electric capacity, rectification circuit, relay, the normally-closed contact of relay, the normally-closed contact of the relay that is connected with power supply successively the coil by rectification circuit and contactor wherein an end be connected, with normally opened contact one tunnel in contactor that power supply is connected successively by electric capacity or transformer, rectification circuit and coil wherein an end are connected, and another road is connected with relay.

During use, click normal open switch, moment switches on power, export a full voltage electric current by rectified current to coil, make armature and iron core adhesive, in the time of armature and iron core adhesive, the normally opened contact in contactor is closed, and power supply provides low-voltage current by electric capacity or transformer, rectification circuit to coil successively.At this moment, after armature and iron core adhesive, both are substantially very close to each other or the gap is minimum, make magnetic resistance between the two minimum, like this, under the effect of the magnetic force that the low-voltage current effect produces, both just can be pulled together consumingly, have guaranteed the normal operation of magnetic.When needing to disconnect adhesive, block power supply, make coil losing electricity and the magnetic force disappearance, like this, under the effect of spring, armature separates with iron core.The effect of electric capacity or transformer is that the current/voltage that provides to coil is provided; Adopt phosphorus content less than 0.1% iron, to utilize phosphorus content less, leave the character of the soft magnetic medium that remanent magnetism is less behind magnetic field, after magnetic field disappears, its magnetic force that obtains in magnetic field rapidly disappears, and remanent magnetism is few, and remaining magnetic force far is not enough to overcome the elastic force of spring, the character of the iron that phosphorus content is little has simultaneously determined its easy distortion, easily comes moulding according to designing requirement.

The present invention compared with the prior art, have advantages of economize on electricity, production and easy to use and reliable, the easy moulding of core configuration.
