Abstract
The utility model discloses an oil tank magnetic shielding device for a transformer. The oil tank magnetic shielding device comprises a magnetic shielding device body of which the outermost layer package is an outer paper groove (2), wherein the outer paper groove (2) is provided with four corners of which two adjacent side faces are connected together, and the corners of the outer paper groove (2) extend along the center line of the outer paper groove (2); the outer package of a silicon steel sheet (1) is fixed by using four corners instead of two corners. By adopting the oil tank magnetic shielding device, corner protecting parts are not required, and the mounting procedure is simplified.
Description
Technical field
The utility model relates to a kind of fuel tank magnetic shielding device, especially a kind of fuel tank magnetic shielding device for transformer.
Background technology
Transformer is as large-scale power device, particularly to oil immersed power transformer, distance between oil immersed power transformer coil and tank wall hour, fuel tank magnetic screen need to be installed, to reduce leakage flux, guarantee the security of operation of transformer, therefore the fuel tank magnetic shielding device for transformer is a kind of important transformer part, at the existing fuel tank magnetic shielding device for transformer, generally to use four paper grooves to divide front and back each two-layer parcel silicon steel sheet, then with contraction bands colligation, form, during magnetic screen assembling, also need the cardboard that adds a plurality of corner protectors and be used for separating magnetic screen and fuel tank threaded base, expend labor and materials and installation difficulty is large, as Fig. 1.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of fuel tank magnetic shielding device for transformer, therefore no longer needs corner protector, has simplified installation procedure.
For achieving the above object, the technical scheme that the utility model is taked is: include and have the magnetic shielding device body that outermost layer packing material is outer paper groove, outer paper groove is set to have four bights that two adjacent side connect, and the bight of outer paper groove is set to extend along the center line of outer paper groove.
Using outer paper groove to carry out outermost packing to silicon steel sheet, owing to having designed outer paper groove, to the external packing of silicon steel sheet, used four bights to be fixed, is no longer to only have two bights to fix, and therefore no longer needs corner protector, has simplified installation procedure.
The utility model has designed, magnetic shielding device body is set to also include without latitude band, contraction bands, ground strip and interior paper groove, ground strip is arranged between the two-layer silicon steel sheet of outermost, on the lateral surface of silicon steel sheet, be provided with without latitude band, without latitude band, be set to be packaged on silicon steel sheet, interior paper groove is arranged between silicon steel sheet and outer paper groove, outer paper groove is set to a side of silicon steel sheet, pack and top and the bottom bending to the inside respectively from the another side of silicon steel sheet, contraction bands is set to tie up outer paper groove, the cross section contour of interior paper groove is set to L shaped, the cross section contour of outer paper groove is set to have a side rectangle of opening.
In the technical program, the outer paper groove with interconnective four bights is important technical characterictic, and the technical field at the fuel tank magnetic shielding device for transformer, has novelty, creativeness and practicality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the prior art in technical background of the present utility model:
Fig. 2 is schematic diagram of the present utility model.
Embodiment
Fig. 2 is an embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include without latitude band 6, contraction bands 5, ground strip 4, outer paper groove 2 and interior paper groove 3, ground strip 4 is arranged between the two-layer silicon steel sheet of outermost 1, on the lateral surface of silicon steel sheet 1, be provided with without latitude band 6, without latitude band 6, be set to be packaged on silicon steel sheet 1, interior paper groove 3 is arranged between silicon steel sheet 1 and outer paper groove 2, outer paper groove 2 is set to a side of silicon steel sheet 1, pack and top and the bottom bending to the inside respectively from the another side of silicon steel sheet 1, contraction bands 5 is set to tie up outer paper groove 2, the cross section contour of interior paper groove 3 is set to L shaped, , the cross section contour of outer paper groove 2 is set to have a side rectangle of opening.
After silicon steel sheet 1 assembling, use and pack for the first time without latitude band 6, re-use interior paper groove 3 and pack for the second time, use 2 pairs of silicon steel sheets of outer paper groove 1 to carry out outermost packing, by contraction bands 5, tightened.
The utlity model has lower feature:
1, owing to having designed outer paper groove 2, to the external packing of silicon steel sheet 1, used four bights to be fixed, be no longer to only have two bights to fix, therefore no longer need corner protector, simplified installation procedure.
2, owing to having designed outer paper groove 2 and interior paper groove 3, to the external packing of silicon steel sheet 1, having used four bights to be fixed, only needed two two-layer packings, is no longer to need four parts.
3, owing to having designed outer paper groove 2, convenient carrying and transportation.
In the fuel tank magnetic shielding device technical field for transformer; Have the magnetic shielding device body that outermost layer packing material is outer paper groove 2 every including, and four bights technology contents that also bight of outer paper groove 2 is set to extend along the center line of outer paper groove 2 that outer paper groove 2 is set to have two adjacent side connections is all in protection range of the present utility model.
