Abstract

The utility model provides a limiting structure for an amorphous alloy oil-immersed transformer body. The limiting structure comprises an oil tank with a tank cover, the transformer body with a bottom clamp, a tank bottom anti-vibration pad, a hanging plate anti-vibration pad and a hanging plate. The transformer body is arranged inside the oil tank, the bottom clamp at the upper end of the transformer body is connected with the tank cover at the upper end of the oil tank through the hanging plate, and the hanging plate anti-vibration pad is installed on the connection portion of the hanging plate and the tank cover. A plurality of symmetrical clamping plates preventing the transformer body from shaking and moving are installed close to the four corners of the transformer body and on the inner walls of the two opposite sides of the oil tank, and the upper ends of the clamping plates are bent towards the direction close to the inner wall of the oil tank. In addition, the tank bottom anti-vibration pad with through holes in the two ends is arranged between the bottom of the transformer body and the bottom of the oil tank and is sleeved with a locating round pipe installed on the bottom of the oil tank through the through holes. According to the limiting structure, the noise of products is lowered obviously, the transformer body is prevented from shaking when the products are transported, and therefore the phenomenon that transformer with small capacity is broken easily when being pulled due to the small conductor section can be avoided.

Description

A kind of amorphous alloy oil immersion type transformer body position limiting structure

Technical field

The utility model relates to amorphous alloy oil immersion type transformer technology field, refers in particular to a kind of amorphous alloy oil immersion type transformer body position limiting structure.

Background technology

Amorphous alloy transformer is exactly the transformer that replaces silicon steel sheet to manufacture with amorphous alloy material, and it significantly obtains wideling popularize of State Grid Corporation of China and Southern Power Grid Company because of energy-saving effect.But due to the particularity of non-crystalline material, iron core can not be squeezed simultaneously.And traditional device body spacing be fuel tank bottom weldering locating pin, end folder is driven location hole, locating pin is inserted in location hole, this bottom localization method makes the noise of product be greater than the noise of the silicon steel product of same capacity, product device body in transportation can wave, the transformer of low capacity is less because of conductor cross-section, in the process of rocking at the device body, easily breaks, thus the potential safety hazard of causing.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of rational in infrastructure, easy to operate amorphous alloy oil immersion type transformer body positioning structure is provided.

For achieving the above object, technical scheme provided by the utility model is: a kind of amorphous alloy oil immersion type transformer body position limiting structure, it comprises fuel tank, the device body of oil-filled transformer, crash roll at the bottom of case, boatswain chair crash roll and boatswain chair, the device body is placed in the inside of fuel tank, the end folder that device is held with it is connected with the case lid of fuel tank upper end by boatswain chair, and the junction of boatswain chair and case lid is equipped with the boatswain chair crash roll, and near four angles of device body and be positioned at the preventer body that a plurality of symmetries are installed on the inwall of the relative both sides of fuel tank and rock the clamp with displacement, this clamp upper end is toward the direction bending near inner wall of oil tank, in addition, crash roll at the bottom of between device body bottom and fuel tank bottom, being furnished with the case of opening perforation in two ends, at the bottom of this case, crash roll is nested in the location pipe that is arranged on the fuel tank bottom by perforation.

The height of described location pipe is less than the height of crash roll at the bottom of case.

At the bottom of described case, the crash roll both side surface is covered with the protruding nail of roundlet column type.

Connecting pore on described boatswain chair is slotted hole.

The utility model, after having adopted such scheme, has reduced the noise of product significantly, has prevented that product device body in transportation from waving, thereby the transformer of avoiding low capacity is because of the less appearance of easily breaking phenomenon of conductor cross-section.

Embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.

Referring to accompanying drawing 1 to shown in accompanying drawing 7, the described amorphous alloy oil immersion type transformer body of the present embodiment position limiting structure, it comprises fuel tank 1, the device body 2 of oil-filled transformer, at the bottom of case, crash roll 3, boatswain chair crash roll 4 and boatswain chair 5, wherein, the case lid 6 at fuel tank 1 top is connected with the end folder 7 in device body 2 by boatswain chair 5, connecting pore 12 on this boatswain chair 5 is slotted hole, guaranteed that device body 2 is unlikely unsettled, device body 2 can be seated at the bottom of case on crash roll 3, for hanging in the process of fuel tank 1, preventer body 2 shakes, boatswain chair crash roll 4 is located at the junction of this boatswain chair 5 and

case lid

6, and 4 clamps 8 are installed on the inwall of fuel tank 1 relative both sides altogether, the height of clamp 8 is about 1/3rd of fuel tank 1 height, its lower end also is about 1/3rd of fuel tank 1 height apart from fuel tank 1 bottom, the interior distance of two clamps 8 is more bigger than upper clamping piece width, generally be greater than 10mm.One end of clamp 8 wants bending at an angle alpha, be generally 30 ° of left and right, can make so the smooth nowel of device body 2, can guarantee again device body 2 chuckings, avoid device body 2 to rock or displacement, in addition, crash roll 3 at the bottom of between device body 2 bottoms and fuel tank 1 bottom, being furnished with the case of opening perforation 10 in two ends, at the bottom of this case, crash roll 3 is nested in the location pipe 9 that is arranged on fuel tank 1 bottom by perforation 10, the height of described location pipe 9 is less than the height of crash roll 3 at the bottom of case, simultaneously, in order to increase shockproof effect, at the bottom of described case, crash roll 3 both side surface are covered with the protruding nail 11 of roundlet column type.

The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection range of the present utility model.
