Abstract
The invention relates to transformer body laminated board treatment technology which is characterized in that a plurality of screw holes are formed in a position close to edges of laminated paper boards of a transformer. High intensity paper screws are screwed into the screw holes with glue so that the laminated paper boards are locked through the screws and the electric glue. Due to the fact that the plurality of screw holes are formed in the position close to the edges of the laminated paper boards of the transformer, the high intensity paper screws are screwed into the screw holes with the glue and the laminated paper boards are locked through the screws and the electric glue, the paper board at each layer is prevented from sliding and cracking, laminated board mechanical strength is improved, the technology is mainly applicable to manufacture of the laminated board and a support board of a high voltage transformer laminated paper board material.
Description
(1) technical field
The present invention relates to a kind of transformer body pressing plate treatment process, belong to transformer manufacture technology.
(2) backgroundTechnology
The electric property of laminated paper board, toughness all are better than electrical laminated plank, thus present stage the high voltage transformer pressing plate generally adopt laminated paper board to replace electrical laminated plank to make.But the laminated paper plate is easy to crack along laminating direction when heating, drying is stressed.Usually the method that adopts is increase the content of glue in laminated paper board and reduce drying time and be subjected to force intensity.The method of conventional anti-cracking can reduce the electric and mechanical performance of transformer pressing plate, and the anti-cracking technique processing method identical with the present invention do not arranged at present.
(3) inventionContent
The purpose of this invention is to provide a kind of new anti-cracking technique processing method, be specially a kind of strength of compressive plate high, safe and reliable transformer body pressing plate treatment process.
The present invention is achieved through the following technical solutions:
A kind of transformer body pressing plate treatment process is characterized in that: lean on into edge on the transformer laminated paper board and attack some holes, band glue is screwed into the high strength paper screw rod, utilizes screw rod and electrician's glue that laminated paper board is locked.
Described transformer body pressing plate treatment process is characterized in that its concrete steps are:
1) on the laminated paper board that processes, beat some apertures apart from the edge with than large opening 40-60mm and other easy strain cracking place, pitch of holes can be adjusted between 80-120mm according to thickness of compressive plate, and the thick Ullage of pressing plate gets the small value;
2) at aperture place tapping, the tapping diameter is adjusted between M16-M24 according to thickness of compressive plate, pitch of holes;
3) with dust catcher, that foreign material, broken end reason is clean, the electrician is put gummed paper be bonded at pressing plate and below lower end, silk hole sealed up, carefully inject electrician's glue, need prevent from producing in glue bubble in this process;
4) select import high strength paper screw rod or laminated paper board screw rod, gluing is screwed into a hole, unnecessary glue is processed clean, puts gummed paper with the electrician and glues dustproofly, enters drying oven vacuumize immersion oil and solidifies.
The invention has the beneficial effects as follows: the present invention leans on transformer pressing plate into edge and attacks some holes, and band glue is screwed into the high strength paper screw rod, utilizes screw rod and electrician's glue that laminated paper board is locked, prevents each layer paperboard slip cracking, improves the pressing plate mechanical strength.Be mainly used in pressing plate, the supporting plate manufacturing of high voltage transformer laminated paper board material.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention;
In figure, 1 laminated paper board, 2 pressing plate winding protruding head gaps, gap under 3 pressing plate iron yokes, 4 paper screw rod paper screw rod or laminated paper board screw rods.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment is a kind of transformer body pressing plate treatment process, it is characterized in that: lean on into edge on the transformer laminated paper board and attack some holes, band glue is screwed into the high strength paper screw rod, utilizes screw rod and electrician's glue that laminated paper board is locked.
The concrete steps of transformer body pressing plate treatment process of the present invention are:
1) on the laminated paper board that processes, beat some apertures apart from the edge with than large opening 40-60mm and other easy strain cracking place, pitch of holes can be adjusted between 80-120mm according to thickness of compressive plate, and the thick Ullage of pressing plate gets the small value;
2) at aperture place tapping, the tapping diameter is adjusted between M16-M24 according to thickness of compressive plate, pitch of holes;
3) with dust catcher, that foreign material, broken end reason is clean, the electrician is put gummed paper be bonded at pressing plate and below lower end, silk hole sealed up, carefully inject electrician's glue, need prevent from producing in glue bubble in this process;
4) select import high strength paper screw rod or laminated paper board screw rod, gluing is screwed into a hole, unnecessary glue is processed clean, puts gummed paper with the electrician and glues dustproofly, enters drying oven vacuumize immersion oil and solidifies.
The present invention relates to high-tension transformer device body pressing plate treatment process, by introducing the locked laminated paper board of paper screw rod band glue, stressed cracking when preventing the pressing plate heating, drying improves strength of compressive plate, increases security reliability.
