Description
Technical field
The utility model relates to electric switch field, particularly the spacing A.C. contactor of one.
Background technology
Contactor is divided into A.C. contactor (voltage AC) and D.C. contactor (voltage DC), and it is applied to electric power, distribution and electricity consumption.Contactor broadly refers in industrial electro and utilizes coil to flow through current induced magnetic field, makes contact closure, to reach the electrical equipment of control load.At present, people use A.C. contactor be all electric pass formula namely to the electromagnet coil power in A.C. contactor, rear generation magnetic, forms attraction, drives contacting circuit, load just can work, but this way has individual shortcoming, namely allowing A.C. contactor produce attraction will be energized, and it be allowed to keep attraction must continue energising, so this contactor does not have spacing function, under the normal state keeping chi to connect, waste the necessary energy.
Utility model content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of oil-filled transformer, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of spacing A.C. contactor, it is characterized in that: described A.C. contactor is made up of main contactor and stop, described main contactor comprises shell by contact, moving contact, main coil, unshakable in one's determination, dynamic unshakable in one's determination, dynamic link unshakable in one's determination, spring and starting switch composition, one end of dynamic iron core is connected on shell by described spring, described main coil is wound on iron core, described contact and moving contact are connected on unshakable in one's determination and dynamic iron core, starting switch is connected in the joint of main coil extraction, described stop is positioned at dynamic side unshakable in one's determination, described stop is by draw-in groove, grab and reset switch composition, described grab and draw-in groove are connected together by clamping, described reset switch is done with on draw-in groove.
Preferably, described grab is fixed on dynamic iron core, and described draw-in groove is fixed on shell.
Preferably, described contact and moving contact are all provided with A, B, C three-phase contact.
Preferably, described dynamic iron core and dynamic link unshakable in one's determination are by being welded and fixed.
Preferably, described contact is made up of bump.
The beneficial effect of above technical scheme is adopted to be: when using this A.C. contactor, when main coil is energized time, acquisition magnetic unshakable in one's determination, magnetic force was greater than from the resistance of spring and then was attracted to by dynamic iron core here unshakable in one's determination this time, and contact and moving contact are connected, time meanwhile, stop is opened and is fixed the position of dynamic iron core, need not be energized under this ensure that the state of fixing in position as main coil.And this A.C. contactor structure is simple, save the energy.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of spacing A.C. contactor of the present utility model.
Fig. 2 is the partial schematic diagram of stop.
Wherein: 1-main contactor, 2-stop, 3-contact, 4-moving contact, 5-main coil, 6-is unshakable in one's determination, and 7-is dynamic unshakable in one's determination, and 8-moves link unshakable in one's determination, 9-spring, 10-starting switch, 11-draw-in groove, 12-grab, 13-reset switch.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As Fig. 1, shown in Fig. 2, a kind of spacing A.C. contactor, described A.C. contactor is made up of main contactor 1 and stop 2, main contactor 1 comprises shell by contact 3, moving contact 4, main coil 5, unshakable in one's determination 6, dynamic unshakable in one's determination 7, dynamic link 8 unshakable in one's determination, spring 9 and starting switch 10 form, dynamic one end of unshakable in one's determination 7 is connected on shell by described spring 9, described main coil 5 is wound on iron core, contact 3 and moving contact 4 are connected on unshakable in one's determination 6 and dynamic unshakable in one's determination 7, starting switch 10 is connected in the joint of main coil extraction, stop 2 is positioned at the dynamic side of unshakable in one's determination 7, stop 2 is by draw-in groove 11, grab 12 and reset switch 13 form, described grab 12 and draw-in groove 11 are connected together by clamping, reset switch 13 is done with on draw-in groove 11, because in the middle of prior art, use A.C. contactor be all electric pass formula namely to the electromagnet coil power in A.C. contactor, rear generation magnetic, form attraction, drive contacting circuit, load just can work, but this way allow A.C. contactor produce attraction to be energized, it is allowed to keep attraction must continue energising, so this contactor does not have spacing function, the necessary energy is wasted under the normal state keeping chi to connect.When using this A.C. contactor, when main coil 1 is energized time, acquisition magnetic unshakable in one's determination, magnetic force was greater than from the resistance of spring 9 and then dynamic iron core was attracted to unshakable in one's determination 6 here this time, and contact 3 and moving contact 4 are connected, time meanwhile, stop 2 is opened and is fixed the dynamic position of unshakable in one's determination 7, need not be energized under this ensure that the state of fixing in position as main coil 5.And this A.C. contactor structure is simple, save the energy.
It should be noted that, as shown in Figure 2, stop 2 is made up of draw-in groove 11, grab 12 and reset switch 13, described grab 12 and draw-in groove 11 are connected together by clamping, and reset switch 13 is done with on draw-in groove 11, after dynamic unshakable in one's determination 7 move to default position, grab 12 is just fixed at the desired location of draw-in groove 11, and when it needs to get back to home position time, just can use reset switch 13, this is that unshakable in one's determination 7 can get back to original position along with the restoring force of spring 9.
In addition, described grab is fixed on dynamic unshakable in one's determination 7, described draw-in groove 11 is fixed on shell, described contact 3 and moving contact 4 are all provided with A, B, C three-phase contact, described dynamic unshakable in one's determination 7 and dynamic link 8 unshakable in one's determination by being welded and fixed, contact 3 is made such simplicity of design by bump and is met practical demand, and structure is simple.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
