Abstract
The utility model relates to an insulating structure of an iron core clamp of a transformer, belonging to the technical field of transformers; according to a technical proposal, the insulting structure comprises an insulating paperboard (1), cushion blocks (2) and boss cushion blocks (3), wherein the cushion blocks and the boss cushion blocks are arranged on the insulating paperboard at interval; the boss cushion blocks are bosses which are extended on a height direction by 10mm and extended on a thickness direction by 5-10mm and arranged on the cushion blocks; the boss cushion blocks are arranged at interval of 400mm; and at least three boss cushion blocks are arranged. The insulating structure disclosed by the utility model has positive effect that in order to prevent a problem of multi-point grounding of an iron core because of non-tight clamping, the insulating structure uses limit operation for the upper surface of an upper iron yoke last level sheet and the lower surface of a lower iron yoke last level sheet; therefore, the insulating structure not only solves the problem of the multi-point grounding of the iron core, but also develops lamination radiating effect.
Description
Technical field
The utility model relates to a kind of transformer core clamping insulation system, belongs to the transformer technology field.
Background technology
Iron core is the basic element of character of power transformer, is made up of magnetic conductor and clamping device.The magnetic circuit that in transformer, constitutes a sealing unshakable in one's determination, and be again the skeleton that coil is installed is an important components very for the electromagnetic performance of transformer and mechanical strength.Group unshakable in one's determination will be made up of core lamination and core construction spare, and core lamination is formed by the electrical steel strip stack, and core construction spare mainly is made up of folder, pad pin, fagging and drawstring etc., guarantees the abundant clamping of lamination to form complete and firm core construction.Between core lamination and folder, pad pin, fagging and the drawstring insulating part is arranged all.Core lamination and folder are drawn ground lead respectively and are received the outside reliable ground of fuel tank, and inside does not allow to exist the multipoint earthing situation.The folder insulation is the insulating part between folder web and the core lamination; High-pressure side, low-pressure side folder from top to bottom all have, and structure is generally adhesion coating pressboard or lamination wooden insulation cushion block structure on the insulating board, and its thickness is consistent with arm-tie and arm-tie insulation; Width H is concordant with iron yoke final stage iron; Upper end or the lower end height yoke final stage iron 10mm that taps a blast furnace, this structure causes that easily folder unshakable in one's determination is not tight, folder unshakable in one's determination tightly then can not cause scurries on the upper yoke final stage sheet and lower yoke final stage sheet sinkage and cause multipoint earthing unshakable in one's determination easily; Thereby the circulation heating takes place, serious overheating fault occurs; If cause the Gas in Oil of Transformer too high levels, caused oil-insulation intensity to reduce, simultaneously, too much gas forms bubble, possibly become " foot bridge ", forms breakdown channel, and structure causes partial discharge.Owing to place not constraint, place simultaneously, can influence the core lamination heat radiation if cardboard suffers lamination.
The utility model content
The purpose of the utility model provides a kind of transformer core clamping insulation system, has both solved the core lamination multipoint earthing, has played the lamination thermolysis again, solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of transformer core clamping insulation system, comprise insulating board, cushion block and boss cushion block, and cushion block and boss cushion block separation are on insulating board.
The boss cushion block is on cushion block, to have short transverse to stretch out the boss that 10mm, thickness direction stretch out 5 ~ 10mm.The every interval 400mm of boss cushion block places one, three boss cushion blocks of minimum placement.
The good effect of the utility model: for preventing the problem that does not tightly cause multipoint earthing unshakable in one's determination owing to folder unshakable in one's determination; The utility model is taked spacing measure to upper yoke final stage sheet upper surface and lower yoke final stage sheet lower surface; Both solve the core lamination multipoint earthing, played the lamination thermolysis again.
Description of drawings
Fig. 1 the utility model embodiment sketch map;
Among the figure: insulating board 1, cushion block 2, boss cushion block 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
A kind of transformer core clamping insulation system comprises insulating board 1, cushion block 2 and boss cushion block 3, and cushion block and boss cushion block separation are on insulating board.
The insulating board height H is concordant with iron yoke final stage sheet.Boss cushion block side is towards core lamination, the boss of upper clamping piece cross-over block up, the boss of lower clamping piece cross-over block is down.
Claims (2)
1. transformer core clamping insulation system, it is characterized in that: comprise insulating board (1), cushion block (2) and boss cushion block (3), cushion block and boss cushion block separation are on insulating board.
2. a kind of transformer core clamping insulation system according to claim 1 is characterized in that the boss cushion block is on cushion block, to have short transverse to stretch out the boss that 10mm, thickness direction stretch out 5 ~ 10mm; The every interval 400mm of boss cushion block places one, three boss cushion blocks of minimum placement.
