The sucking disc type electromagnetic mechanism comprises an armature which is installed on a movable bridge support, wherein the lower portion of the movable bridge support is provided with a restoring spring fixed on a driving frame. The electromagnetic mechanism is characterized in that a sucking disc type electromagnet which is matched with the armature is arranged on the driving frame, and is composed of an iron core, a cylinder and a coil, wherein the cylindrical iron core penetrates through the coil, and is fixed on the center of the cylinder, and the coil is connected with a switch control circuit which can be started in high voltage and maintained in low voltage. The sucking disc type electromagnetic mechanism of transfer alternating current contactor solves the weaknesses of high cost, low efficiency and large volume of an electromagnetic mechanism of a transfer alternating current contactor in the prior art, has the advantages of low cost, high efficiency and small volume, and greatly improves the performance and working reliability.
Description
Technical field
The utility model belongs to the recloser field, is specifically related to the transhipment formula A.C. contactor sucked type electromagnetic mechanism of 220V, 380V all size model.
Background technology
Transhipment formula A.C. contactor is a kind of device to supply line, power consumption equipment enforcement open and close function, and the electromagnetic mechanism of the transhipment formula A.C. contactor of producing in the A.C. contactor industry is that double-H groove weld font iron core, unicoil are formed (CJ12) at present.U font core volume is big, and the single coil volume is also big, and its material cost is just high like this, and power consumption is big, owing to the scope range of the fluctuation of voltage broad, very easily burns out coil, and bigger interchange noise pollution is caused in the working site that the people is arranged in 220V or 380V alternating current circuit.
The utility model content
The purpose of this utility model is low, the bulky defective of electromagnetic mechanism cost height, efficient that solves prior art transhipment formula A.C. contactor, provide that a kind of cost is low, efficient is high, volume is little, the transhipment formula A.C. contactor sucked type electromagnetic mechanism that performance and functional reliability improve greatly.
The utility model is achieved through the following technical solutions:
It is a kind of transhipment formula A.C. contactor sucked type electromagnetic mechanism, comprise the armature that is installed on the moving bridge bracket, moving bridge bracket below is provided with the back-moving spring that is fixed on the gear frame, it is characterized in that gear frame is provided with the sucked type electromagnet that mates with armature, described sucked type electromagnet is made up of iron core, cylinder body, coil, columniform iron core passes the center of coil stationary at cylinder body, and coil is connected with the ON-OFF control circuit of high voltage startup, low voltage sustain.
Dishwashing formula electromagnet is arranged on the gear frame corresponding with armature position.
Armature is plate shaped.
Cylinder body is made up of the cylinder sleeve and the circular chassis of tubular, and described cylinder sleeve and chassis are integral structure or split-type structural.When adopting integral structure, the mode of can adopt car, milling is carried out the time processing moulding to section bar; When adopting the split-type structural formula, cylinder sleeve and chassis process respectively, adopt welding or other mode to make up then.
Iron core of the present utility model, cylinder sleeve, chassis also can be integral structures, and can adopt the method one-shot forming of casting this moment.
Iron core, cylinder body, armature material are electrical pure iron or mild steel.
Compared with the prior art, the utility model has the advantages that:
The sucked type electromagnet adopt iron core interior, coil placed in the middle, cylinder sleeve totally enclosed type magnetic loop structure outside, and leakage field is reduced greatly, electromagnetic efficiency improves greatly.Under equal-wattage, improved the electromagnetic force of electromagnet greatly; Under the suitable situation of electromagnetic force, can correspondingly reduce the volume of electromagnet, and its used armature is plate shaped, the used steel of cylinder body and armature have so just been reduced greatly, and because of its magnet spool in cylinder body, its volume is reduced greatly, the copper material that coil is used reduces greatly, so just can significantly reduce the consumption of steel and copper material, the material cost of whole electromagnetic mechanism is reduced greatly.
Because of its circuit module with high voltage startup, low voltage sustain is connected, adopt DC operation, than U font electromagnetic mechanism, saved electric energy (economize on electricity is more than 90%) greatly, easy burn-out coil has not improved the reliability of contactor work again, and the interchange noise pollution that produces when having eliminated the contactor operation.
In sum, the sucked type electromagnetic mechanism reduces greatly than U font electromagnetic mechanism cost, both saved the consumption of steel and copper material, saved electric energy, eliminated the interchange noise, not the easy burn-out coil, improved the reliability of contactor work, again because of circuit module externally, make maintenance, change simple and convenient, avoided U font electromagnet to burn out changing behind the coil must the dismounting contactor trouble.
