Abstract
The utility model relates to a compaction structure, in particular to a large transformer body compaction structure. The structure comprises a body, an upper clamp is arranged on the body and connected with the body through a pressing piece, an insulated pressing cylinder is arranged in the body, and the insulated pressing cylinder and the pressing piece are fixed through a pressing piece limit pin. The structure is simple and has strong practicability.
Description
Technical field
The utility model is a kind of compressing structure, particularly a kind of high-power transformer device body compressing structure.
Background technology
Conventional structure of the prior art is the metal crimp pin structure, for high voltage transformer, causes the trouble of insulation distance anxiety easily, does not with great difficulty cause the discharge in insulation phenomenon if handle.
Chinese patent CN201336211 discloses a kind of compressing structure of transformer body, is included in the auxiliary pressure plate structure that is provided with on the pressing plate, and auxiliary pressure plate structure is provided with the pressure pin structure.The compressing structure that the utility model provides is applied to the fixing of transformer body, combines the characteristics of pressing pin structure and auxiliary pressure plate structure, can regulate degree of tightness, and bigger with the pressing plate contact area, and thrust is also bigger, and is fastening effective.This utility model structure relative complex, and compressing structure poor effect.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of transformer end Electric Field Distribution that makes more even, the high-power transformer device body compressing structure that insulating Design is oversimplified.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of high-power transformer device body compressing structure comprises the device body, and described device is provided with upper clamping piece on one's body, upper clamping piece is connected with the device body by casting die, be provided with the insulation cylinder pressure in the described device body, insulation cylinder pressure and casting die fix by the casting die spacer pin, also are provided with device body pressing plate under the insulation cylinder pressure.The contact area of insulation cylinder pressure and pressing plate has bigger increase, makes device body axial compression more reliable, has reduced the harm of the composition of metal iron filings when the metal bolts lemon is tight to transformer, makes the end Electric Field Distribution more even, and insulating Design is oversimplified; Insulation cylinder pressure described here can be a monoblock, also can be two of boundary each minutes with the center line,
As preferably, described insulation cylinder pressure by last insulation cylinder pressure, regulate the insulation cylinder pressure and down the insulation cylinder pressure forms, describedly go up the insulation cylinder pressure, regulate the insulation cylinder pressure and the cylinder pressure that insulate down fixes by the cylinder pressure spacer pin.
As preferably, described insulation cylinder pressure and casting die fix by rectangle casting die spacer pin; Described insulation cylinder pressure, adjusting insulation cylinder pressure and the following insulation cylinder pressure gone up fixes by cylinder cylinder pressure spacer pin.
As preferably, describedly go up the insulation cylinder pressure, regulate the insulation cylinder pressure and down the insulation cylinder pressure successively from top to bottom mutual superposition form.
As preferably, described cylinder cylinder pressure spacer pin and last insulation cylinder pressure, regulate the insulation cylinder pressure and down the insulation cylinder pressure plug.
Therefore, the utility model provides high-power transformer device body compressing structure, and is simple in structure, practical.
