Description
Technical field
The utility model is related to a kind of being applied in high-power transformer fuel tank to fix magnetic screen stud detecting tool, belongs to big
Type oil tank of transformer fixes magnetic screen stud detection technique field.
Background technology
High-power transformer fuel tank is big because of its tank wall area, and eddy-current loss therein is very big.In order to avoid leakage magnetic flux is disperseed, subtract
The loss that few leakage magnetic flux is caused, need to place the plate i.e. magnetic cup that some magnetic materials are made between the coil of transformer and fuel tank
Cover.In order to install, fix and fastening magnetic shield panel, inner wall of oil tank need to set a large amount of studs（400-500 or so）, method to set up
It is stud welding mode.
After stud welding, be to the physical dimension of all studs, perpendicularity and weld strength（Moment of torsion）Carried out etc. project
Check.The method for used during dimensional measurement is many packet size repeated measurements of stud one by one, and the instrument for using is box chi.Due to
Welded stud quantity is more and drawing size and Geometrical Tolerance Principle are very tight, even if after total plus tight inspection one by one, also often going out
Now indivedual stud dimension overproofs, dislocation or the problems such as stud profile deflection, cause fuel tank magnetic screen cannot normal mounting use.And
The foreign matter produced when erecting yard is repaired and polished easily pollutes fuel tank, device body and erecting yard, easily causes transformer discharge, hits
The serious quality problems such as wear.
Divided respectively by the physical dimension of the physical dimension to tank wall stud welding drawing requirement, magnetic shield panel requirement
Analysis, and field operation observation magnetic shield panel actual installation situation, it is believed that only " entire row permutation " stud dimensional accuracy and morpheme
Tolerance all meets the requirements, and just can guarantee that the normal mounting of magnetic screen.
Utility model content
The purpose of this utility model is to provide a kind of being applied in high-power transformer fuel tank and fixes magnetic screen stud detection work
Dress, stud inspection is carried out using this frock, only need to check whether tank wall permutation welding screw all can enter to confine position, it becomes possible to
The judgement stud of " simple, quick, accurate, directly perceived ", the drawing physical dimension, arrangement position and its morpheme involved by it is public
Difference（Perpendicularity）It is very clear Deng involved design drawing size requirement.Measured with this detecting tool instrument simultaneously, now only needed
One people with regard to can it is independent, simple, efficiently checked；Quantization is truly realized using this frock tool to check, effectively prevent mistake
The generation of missing inspection problem, improves operating efficiency, and portable construction solves the above mentioned problem that background technology is present.
The technical solution of the utility model is：
One kind is applied in high-power transformer fuel tank fixes magnetic screen stud detecting tool, comprising big anti-deformation plate, small anti-
Deformed plate, circular hole, transformer box wall, stud and handle, the stud for multiple, uniform welding in the inner side of transformer box wall,
Multiple studs are divided into some groups, and on same vertical plane, two groups of adjacent studs be arranged in parallel every group of center line of stud；It is described
Big anti-deformation plate is rectangular slab, is arranged on transformer box wall inside front, between two adjacent groups stud, small anti-deformation plate
Quantity is multiple, is symmetricly set on the both sides of big anti-deformation plate two-by-two respectively, and matching is fastened on two studs adjacent in every group
Between；The two ends of the big anti-deformation plate are provided with handle, and several circular holes are evenly arranged on big anti-deformation plate.
Length of the distance between the described two adjacent small anti-deformation plates more than small anti-deformation plate.
The vertical plane of every group of center stud line be arranged in parallel with the vertical plane of the longitudinal centre line of big anti-deformation plate.
The size of the big anti-deformation plate is, thickness 25mm, width 268mm, length 2500mm.
The size of the small anti-deformation plate is, thickness 25mm, width 38mm, length 20mm.
A diameter of 50mm of the circular hole.
The postwelding of the stud is highly 25 mm.
The quantity of the circular hole is 60.
Good effect of the present utility model：Portable construction, only needs the people just can be independent, simply, efficiently checked, carries
High workload efficiency；Quantization is truly realized using this frock tool to check, effectively prevent the generation that problem is examined in mistakes and omissions.
