Description
Technical Field
The utility model relates to a fastening component of transformer tank magnetic screen, in particular to transformer tank magnetic screen dysmorphism nut fastening structure.
Background
When the plate type magnetic shielding is installed on the transformer oil tank, two layers of insulating paperboards are wrapped outside the magnetic shielding, and the steel clamp is required to be welded densely on the wall of the oil tank, so that the steel clamp is smashed to fix the magnetic shielding. Smash the steel card and lead to the appearance pleasing to the eye, inconvenient dismantlement magnetic shield after fixed brings the difficulty for overhauing the magnetic shield, and a large amount of welding steel cards are wasted time and energy simultaneously in the box.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a remedy prior art not enough, provide a easy dismounting, firm reliable transformer tank magnetic screen special-shaped nut fastening structure.
The utility model discloses a realize through following technical scheme:
the utility model provides a transformer tank magnetic shield dysmorphism nut fastening structure, is including installing the oil tank on the transformer, oil tank surface mounting magnetic shield, characterized by: the oil tank wall is welded with a stud, an insulating paper board arranged on the stud is arranged between the oil tank wall and the magnetic shield, a paper tube is inserted into the magnetic shield hole, a washer is sleeved on the paper tube, and a special-shaped nut is fastened on the stud.
And a disc spring is arranged between the washer and the special-shaped nut.
The gasket is provided with an air guide groove.
The utility model has the advantages that: the assembly is simple, the fixing is reliable, the attractive appearance of the oil tank magnetic shielding is ensured, the disassembly is convenient, certain damping magnetic shielding and tank wall vibration transmission effects are achieved, the vibration of the tank wall surface absorbing the oil body transmission can be reduced, and therefore the noise is reduced.

Detailed Description
The attached drawing is a concrete embodiment of the utility model. This embodiment is including installing oil tank 1 on the transformer, 1 surface mounting magnetism shielding 2 of oil tank, 1 tank wall welding double-screw bolt 3 of oil tank, is equipped with the insulating paper board 4 of arranging in on the double-screw bolt 3 between 1 tank wall of oil tank and magnetism shielding 2, and 2 downthehole paper pipes 5 of inserting of magnetism shielding are equipped with packing ring 6 on the paper pipe 5, and the inherent special-shaped nut 7 has on the double-screw bolt 3. A disc spring 8 is arranged between the washer 6 and the special-shaped nut 7. The gasket 6 is provided with an air guide groove 9.
Adopt the utility model discloses a transformer tank magnetic screen dysmorphism nut fastening structure, its preparation flow is: manufacturing a sample plate according to the central size of the magnetic shielding hole, taking the central horizontal line of the stud in the middle as a datum line, placing the sample plate at the intersection position of the datum line and the height central line of the magnetic shielding for positioning, and welding the stud by adopting a stud welding machine; punching a plurality of round holes when the magnetic shielding silicon steel sheets are blanked on the silicon steel sheet automatic shearing line, brushing a curing agent on the stacked silicon steel sheets, standing, curing and forming to prepare a punched plate type magnetic shielding; cutting and blanking the insulating paper board, stacking, uniformly marking and drilling a plurality of round holes; manufacturing a special-shaped nut; sawing a phenolic paper tube with a certain length; manufacturing a glass cloth plate gasket, drilling a hole and opening an air guide groove; milling a gas guide groove on one surface of the large washer and blackening; and (5) purchasing the disc spring.
An insulating paper board 4 (or a rubber plate) is placed on a stud 3 of the wall of an oil tank 1, a punching type plate type magnetic shielding 2 is placed, a phenolic paper tube 5 is inserted into a hole of the plate type magnetic shielding 2, two glass cloth plate gaskets 6 or a blackened large gasket 6 are sleeved on the paper tube 5, an air guide groove 9 is vertically arranged, and a special-shaped nut 7 is sleeved on a disc spring 8 and assembled on the stud 3.
Generally, the magnetic shield 2 is tightly fixed at three or four places, one place is grounded by a large blackened gasket, and the other places are insulated by glass cloth gaskets. When the magnetic shield 2 is more than 10mm thick, a 3mm rubber plate can be arranged between the magnetic shield and the wall of the oil tank 1, so that the vibration of the tank body, which is transmitted by oil bodies, can be reduced on the surface of the wall of the tank, and the noise is reduced.
