Abstract

The utility model relates to an adjustable structure of a cushion block under a transformer coil, comprising a lower clip (7), a cushion block (5), an asbestos gasket (4), a porcelain briquetting block (3) and a silica gel cushion (2); It is characterized in that two screws are welded on the spacer (5) to cooperate with the back-stopping hexagonal flange nut (6), and a corresponding hole is opened at the corresponding position of the lower clamp (7), and the screw head extends into the hole. Because the utility model makes the spacer into a movable type, the hexagonal flange nut of the backstop can be adjusted when the coil is set, so that the top surface of the porcelain pressing block on the spacer is on the same level to ensure a good insulation distance. This structure improves the qualified rate of the suit, reduces the difficulty of refurbishment, and reduces the times of pressing and adjusting.

Description

The adjustable structure of the cushion block under the transformer coil

technical field

The utility model relates to an adjustment structure of a transformer coil, in particular to an adjustable structure of a cushion block under a transformer coil, and belongs to the technical field of power transformers.

Background technique

When the coils of dry-type transformers are assembled, they generally adopt the pull plate structure. The upper and lower clamps are connected into a whole through the pull plate. When the position of the clamp and the core is shifted, the position of the lower clamp and the coil cannot be adjusted, and the main insulation distance between the coil and the core cannot be guaranteed, which brings great difficulty to the final assembly.

Utility model content

The purpose of this utility model is to provide a new type of lower pad structure with adjustable coil position, which improves the pass rate of the assembly on the one hand and ensures the main insulation between the coil and the core on the other hand. The distance fully guarantees the safety of the transformer.

In order to achieve the above-mentioned purpose, the utility model is achieved by taking the following technical solutions:

An adjustable structure of a cushion block under a transformer coil, including a lower clip 7, a cushion block 5, an asbestos gasket 4, a porcelain pressing block 3 and a silica gel pad 2; it is characterized in that two A screw cooperates with the backstop hexagonal flange nut 6, and has a corresponding hole at the corresponding position of the lower clip 7, and the screw head stretches into the hole.

The aforementioned adjustable structure of the cushion block under the transformer coil is characterized in that the hole is a round hole.

Because the utility model makes the spacer into a movable type, the hexagonal flange nut of the backstop can be adjusted when the coil is set, so that the top surface of the porcelain pressing block on the spacer is on the same horizontal plane to ensure a good insulation distance. This structure improves the qualified rate of the suit, reduces the difficulty of renovation, and reduces the times of press-fitting adjustments.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is specifically introduced as follows:

Fig. 1 is a structural schematic diagram of the utility model, and Fig. 2 is a partial schematic diagram of Fig. 1 . As shown in Figures 1 and 2, the adjustable structure of the cushion block under the transformer coil of the present invention consists of a coil 1, a silica gel pad 2, a porcelain briquetting block 3, an asbestos gasket 4, a pad block 5 and a hexagonal flange nut for backstopping. 6. The lower clip 7 and the iron core 8 are composed. Two screws are welded on the pad 5, and the hexagonal flange nut 6 is screwed on it, and two round holes or other forms of holes are opened on the corresponding position of the lower clip, and the screws stretch out from the holes. Put the asbestos spacer 4, porcelain briquetting block 3 and silica gel pad 2 successively on the spacer. By adjusting the backstop hexagon flange nut 6, the top surface of each pad and the iron yoke pad 9 are on the same plane. After the coil is assembled, it is pressed on the ceramic pressure block, and the porcelain pressure block is placed on the cushion block, and then adjusted by the hexagonal flange nut, and the spacer 5 can clamp the coil through the action of the screw, so that the coil and the core The window height spacing meets the main insulation requirements.

The main insulation distance between the coil and the iron core of this structure is easy to ensure, the qualified rate of the package is greatly improved, and the difficulty of repairing is greatly reduced, thereby improving labor productivity.

The above-mentioned embodiments do not limit the present utility model in any way, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.

Claims (2)

1. the adjustable structure of transformer coil lower cushion block comprises lower clamping piece (7), cushion block (5), asbestos washer (4), porcelain briquetting (3) and silicagel pad (2); It is characterized in that being welded with two screws on described cushion block (5), cooperate with retaining hexagon nut with flange (6), have corresponding hole in the relevant position of lower clamping piece (7), head of screw puts in the hole.

2. the adjustable structure of transformer coil lower cushion block according to claim 1 is characterized in that described hole is a circular hole.
