Abstract
The utility model discloses an extinguishing coil compressing structure, which relates to the technical field of the transformer, in particular to the technical field of the extinguishing coil of the transformer. The extinguishing coil compressing structure comprises an iron core and an extinguishing coil covered on the circumference of the iron core, the lower end of the iron core is fixed on a lower clamping component, an upper clamping component is firmly connected at the upper end of the iron core, the base seat and the upper clamping component are tightened through a tensile rod, and the extinguishing coil compressing structure is characterized in that a pressing nail is arranged between the upper clamping component and the iron core. The upper clamping component is connected with the iron core through the pressing nail in the extinguishing coil compressing structure, when the upper clamping component and the base seat are tightened through the tensile rod, the space between the upper clamping component and the iron core can be adjusted through the pressing nail, the gap between the upper clamping component and the iron core is reduced, the air gap in the extinguishing coil iron core is reduced, the safety factor is higher, when being in use, the extinguishing coil compressing structure is safer, the service life of the extinguishing coil type transformer is enhanced, the structure is simple, and the service life of the transformer is prolonged.
Description
Technical field
The utility model relates to the technical field of transformer, relates in particular to the technical field of transformer arc suppression coil.
Background technology
Arc suppression coil is a reactance coil that band is unshakable in one's determination.During normal the operation, because the neutral point voltage to earth is zero, no current on the arc suppression coil, after single phase ground fault takes place, the earth point of earth point and arc suppression coil forms short circuit current, and neutral point voltage raises to phase voltage, acts on the arc suppression coil, to produce an inductance current, at the earth fault place, the capacitance current at this inductive current and earth fault place offsets, thereby has reduced the electric current of earth point, electric arc is easy to from horizontal blanking, has improved the electricity consumption reliability.Therefore arc suppression coil is widely applied in the transformer, but can have air gap in the arc suppression coil iron core, and according to the difference of arc suppression coil compensation electric current, the quantity of air gap is also different.The air gap of core limb is because the insulating pad of pad in air gap forms, and is highly to be the discus of 50mm between the air gap.Because during the arc suppression coil operation, can make produce very big vibrations and noise unshakable in one's determination because the magnetic hysteresis of silicon steel sheet is flexible, when iron core band air gap, vibrations and noise can increase.When iron core did not press tightly, noise that iron core brings and vibration will be bigger, and discus can be damaged because of vibrations, will cause great hidden danger of quality when arc suppression coil moves.Traditional design all is to adopt the tension structure of drawing screw rod, when compressing coil, compress iron core exactly, but such shortcoming is because the error when coil and unshakable in one's determination the manufacturing, caused often occurring that coil has compressed and iron core does not also compress, perhaps core pressing and cushion block on the coil also is in loosening state, make the electric property of arc suppression coil beat very big discount.
Summary of the invention
The utility model purpose provides a kind of electric property that improves arc suppression coil, and is simple in structure, the arc suppression coil compressing structure of long service life.
The utility model adopts following technical scheme for achieving the above object:
The utility model comprises iron core and is wrapped in the arc suppression coil of periphery unshakable in one's determination, lower end unshakable in one's determination is fixed on the lower clamping piece, fixedlying connected with upper clamping piece in upper end unshakable in one's determination, by drawing the screw rod tension, it is characterized in that between described base and the upper clamping piece: be provided with between above-mentioned upper clamping piece and the iron core and press nail.
Upper clamping piece of the present utility model is threaded with pressing between the nail.
Riveted joint between upper clamping piece of the present utility model and the pressure nail.
The utility model adopts such scheme, compared with prior art has the following advantages:
1, between upper clamping piece and the iron core by pressing nail to be connected, when drawing screw rod tension upper clamping piece, can utilize pressure to follow closely the spacing of regulating between upper clamping piece and the iron core with base, reduce space between the two, reduced the air gap in the arc suppression coil iron core, coefficient of safety is higher, and is safer during use.
2, owing to air gap in the arc suppression coil iron core has reduced, during the arc suppression coil operation, reduced because flexible iron core vibrations and the noise that brings of the magnetic hysteresis of silicon steel sheet, also avoided under the situation that iron core does not press tightly simultaneously, noise that iron core brings and vibration, the discus that is arranged in the insulating pad air gap can not be damaged because of vibrations, has improved the useful life of the transformer of arc suppression coil type.
Error during 3, owing to coil and unshakable in one's determination the manufacturing, the utility model is under the situation that adopts technique scheme, make that iron core had also been realized compressing when coil compressed, cushion block on the coil has also been realized compressing in core pressing in addition, make the electric property of arc suppression coil obtain reinforcement, simple in structure, prolonged useful life of transformer.
