Description

Transformer bottom positioner

Technical Field

The utility model relates to a transformer structure field, more specifically say, relate to a transformer bottom positioner.

Background

In the positioning device for the transformer inner body and the oil tank in the prior art, the conventional paper board winding and glue bonding method structure is adopted, so that the paper board is required to be dried in vacuum and wound on the positioning nail at the bottom of the oil tank, the glue is bonded, and the cleanliness of transformer oil is influenced by the glue; when the transformer body is placed in the oil tank, the transformer body legs easily extrude and damage the paper board, so that the transformer body and the oil tank are electrified; when the device is operated and transported, the inner device body shakes, so that the risk of electrifying after the paperboard is worn out exists; after the paperboard glue is soaked in the insulating liquid for a long time, the risk of falling off exists, so that the power is switched on; the transformer is inclined outwards as required during operation and transportation, and the risk of falling of the transformer body and the box bottom exists.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome the fragile problem of traditional transformer in the use that exists among the prior art, now provide a transformer bottom positioner that has stability height.

The utility model discloses a transformer bottom positioner, include the transformer body as the main part, transformer body lower extreme be equipped with the installation base, installation base lower extreme be equipped with the insulating layer, the installation base on open the bolt hole that has a plurality of equipartitions, the installation base pass through bolt hole and screw fixed connection with the insulating layer, the installation base on open the dashpot that has a plurality of equipartitions, the dashpot in be equipped with buffer.

The insulating layer be 6.5mm thickness epoxy glass cloth board insulating cover, adopt bolt hole and bolt and installation base fixed, prevent that insulating cover from droing, this design increases dielectric strength, has guaranteed the reliability of installation, transportation, operation.

In the use, buffer can absorb the pressure between transformer body and installation base effectively to the protection installation base prolongs the life of installation base, improves the stability in the transformer body use.

Preferably, the buffer device comprises fixing plates arranged on the left side and the right side of the bottom of the buffer groove, a spring pin is arranged at the upper end of each fixing plate, a buffer plate is arranged at the upper end of each spring pin, a first spring is sleeved on each spring pin, and the upper end and the lower end of each first spring are respectively welded with the bottom end of each spring pin and the lower end face of each buffer plate.

Preferably, a long pin rod is arranged between the buffer plate and the fixing plate, limiting blocks are arranged at the left end and the right end of the long pin rod respectively, a pin hole used for installing the long pin rod is formed in the center of each limiting block, the bottom of each limiting block is welded with the lower end face of the buffer plate, a second spring is sleeved on the periphery of the long pin rod, compression rings are welded at the left end and the right end of the second spring respectively, push rods are welded at the side ends of the compression rings, rocker arms are hinged to the other ends of the push rods, the other ends of the rocker arms are hinged to one ends of hinge blocks, and the other ends of the hinge blocks are welded with the sides of the fixing plate.

In the use, this meeting of transformer extrudees the buffer board earlier, the buffer board be the better rubber slab of elasticity, spring catch can extrude a spring in extrusion process, can absorb the pressure that the transformer body brought at a spring deformation in-process, when a spring is compressed, the buffer board can translate slightly, the rocking arm can drive push rod and clamping ring and remove to extrude No. two springs at translation in-process, realizes through the deformation of a spring and No. two springs the utility model discloses a multistage buffer function.

The utility model discloses following beneficial effect has: simple structure, convenient manufacture and high stability.
