Description

Dry-type transformer anchor clamps subassembly

Technical Field

The utility model relates to a dry-type transformer, in particular to dry-type transformer anchor clamps.

Background

The dry type transformer can be directly installed in a load center due to good safety and fire resistance; the maintenance is free, the installation is simple and convenient, and the comprehensive operation cost is low; the moisture resistance is good, and the environment is not polluted; the air cooling system has the advantages of low loss, low local discharge capacity, low noise, strong heat dissipation capability, capability of operating at 150% rated load under the forced air cooling condition, high reliability and the like, and is adopted by users.

The dry type transformer is an important electrical device in a power grid, and in the prior art, the waterproof epoxy resin cast dry type transformer mainly structurally comprises an upper clamping piece and a lower clamping piece which are usually made of channel steel, pull nails are welded on pull plates, the upper clamping piece and the lower clamping piece are connected into a frame, a coil is tightly pressed through pressing nails and insulating cushion blocks on the upper clamping piece, and finally the transformer forms a firm whole. The pulling plate is combined with the two side columns of the iron core, the low-voltage coil is sleeved on the iron core column, and the high-voltage coil is positioned outside the low-voltage coil.

Since the pull plate is welded with the pull nail protrusion (as shown in fig. 6), the pull plate can be in the way when the low-voltage coil is sleeved, so that the inner diameter of the low-voltage coil is often designed to be a little larger. The clamping and pulling plate structure of the current dry-type transformer is basically as follows: the upper end and the lower end of the pulling plate are welded with a pulling nail shaft which is connected with a matched hole on the clamping piece. When the manufacture is carried out, the manufacture of the pulling plate can be completed only by the working procedures of sheet metal, drilling, welding and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a dry-type transformer anchor clamps subassembly for the assembly is more convenient, eliminates the shearing force, makes the connection of going up folder, lower folder and arm-tie more reliable, reinforcing dry-type transformer overall structure intensity.

The purpose of the utility model is realized like this: the utility model provides a dry-type transformer anchor clamps subassembly, is including connecting the arm-tie of upper clamp spare and lower clamp spare, go up the clamp and offer on the lower clamp with arm-tie complex notch, the both ends embedding of arm-tie the notch sets up, the notch is processed into the calabash shape, and the arm-tie both ends correspondence is processed into the calabash shape.

Compared with the prior art, the beneficial effects of the utility model reside in that, the utility model discloses a folder and lower folder are connected to the notch cooperation arm-tie of calabash shape for it is more convenient to assemble, eliminates the shearing force, makes folder, lower folder more reliable with being connected of arm-tie, reinforcing dry-type transformer overall structure intensity. The utility model discloses can be used to among the dry-type transformer.

In order to make the assembly more convenient, the upper clamping piece and the lower clamping piece have the same structure and are symmetrically arranged, the upper clamping piece comprises a vertical part and bending parts at the upper end and the lower end, and the notch is formed in the vertical part.

In order to ensure that the lower clamping piece is more reliably installed and fixed, a bolt is connected to a bending part at the lower end of the lower clamping piece, and the lower clamping piece is fixed on the base through the bolt.

In order to ensure that the structure reliability of the upper clamping piece, the lower clamping piece and the pulling plate after connection is better, the upper clamping piece, the lower clamping piece and the pulling plate are the same in thickness, and the end faces of the pulling plate are flush with each other after the two ends of the pulling plate are embedded into the upper clamping piece and the lower clamping piece.

As a further limitation of the present invention, the upper clamp and the lower clamp are made of steel plates by bending.
