Description
Technical field
The utility model belongs to the recloser field, is specifically related to the direct shipment type A.C. contactor sucked type electromagnetic mechanism of 220V, 380V all size model.
Background technology
Direct shipment type A.C. contactor sucked type electromagnetic mechanism is a kind of device of supply line, power consumption equipment being implemented the open and close function.The electromagnetic mechanism of the direct shipment type A.C. contactor of producing in the A.C. contactor industry is divided into double-H groove weld font iron core, twin coil and two kinds of energy-conservation magnetism holding types (CJ20) at present.U font dual coil electromagnetic mechanism, because of U font core volume is big, two coils, used like this steel and copper material consumption are just big, the cost of electromagnetic mechanism is just high, and power consumption is big, in 220V or 380V alternating current circuit,, very easily burn out coil, and the interchange noise pollution is caused in the working site that the people is arranged owing to the scope range of the fluctuation of voltage broad; The armature of energy-conservation magnetism holding type electromagnetic mechanism is substituted by rare earth permanent magnet, makes the electromagnetic mechanism adhesive for during Contactor Starting transient forward voltage of coil, then keeps attracting state by the magnetic force of permanent magnet; In the time will disconnecting, produce an opposing magnetic field for again instantaneous reverse voltage of coil and allow contactor disconnect.Though it has overcome the shortcoming of above-mentioned U font electromagnetic mechanism, volume is also little, but because of its permanent magnet cost height, make the total cost of electromagnetic mechanism not low, the more important thing is, damage, can cause the A.C. contactor can't disjunction in case start with the electronic circuit that disconnects, thereby lose its automatically effect of control, perhaps this be that the large tracts of land of failing is so far promoted the main cause of opening.
The utility model content
The purpose of this utility model is to solve prior art direct shipment type A.C. contactor electromagnetic switch mechanism electromagnetic iron cost height, low, the bulky defective of efficient, provide that a kind of cost is low, efficient is high, volume is little, the direct shipment type 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 direct shipment type A.C. contactor sucked type electromagnetic mechanism, comprise the armature that is connected with travel(l)ing rest, it is characterized in that being provided with on the body and the corresponding sucked type electromagnet of armature on the travel(l)ing rest, 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.
The sucked type electromagnet is arranged on the body corresponding with travel(l)ing rest upper armature below.
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 it is connected with high voltage startup, low voltage sustain circuit module, 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 ac operation; More energy-conservation magnetism holding type electromagnetic mechanism, its material cost is relatively low, the more important thing is that it does not change the performance of former A.C. contactor, has overcome its control circuit of magnetism holding type electromagnetic mechanism and has damaged the critical defect that the contactor that causes can't disconnect.
In sum, the sucked type electromagnetic mechanism is low than U font electromagnetic mechanism cost, both save the consumption of steel and copper material greatly, reduced the height of contactor again, also saved electric energy, eliminated the interchange noise, the easy burn-out coil has not 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.Material cost than the magnetism holding type electromagnetic mechanism is relatively low, has overcome its control circuit and has damaged the critical defect that contactor can't disconnect.
