Description

Fixing and supporting device for high-voltage neutral point grounding wire of transformer

Technical Field

The utility model relates to a fixed support device of transformer high pressure neutral point earth connection belongs to transformer technical field.

Background

In the power transformer industry, a high-voltage neutral point of a transformer is generally grounded through a neutral point protection device. When the neutral point protection device is far away from the high-voltage neutral point sleeve of the transformer and the neutral point grounding wire is long, a fixed supporting device needs to be arranged for fixedly supporting the neutral point grounding wire. The fixed supporting device is generally installed on a site foundation, but when the site conditions are limited and the fixed supporting device cannot be installed on the foundation, the fixed supporting device needs to be additionally installed on the transformer.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fixed support device of transformer high pressure neutral point earth connection can satisfy the user and install strutting arrangement's requirement additional on the transformer body, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

the utility model provides a fixed bolster device of transformer high pressure neutral point earth connection, contain post insulator, fastener A, the vertical support post, fastener B, the bearing diagonal post, fastener C, fixed plate A, fastener D, fixed plate B, backup pad and transformer tank, fixed plate A fixes the top at transformer tank, the side at transformer tank is fixed to the backup pad, fixed plate B fixes in the backup pad, fastener D is passed through to the lower extreme of vertical support post and fixes on fixed plate B, post insulator passes through fastener A and fixes the upper end at the vertical support post, fastener B is fixed on the vertical support post through to the upper end of bearing diagonal post, the lower extreme of bearing diagonal post passes through fastener C and fixes on fixed plate A.

The fastening piece A, the fastening piece B, the fastening piece C and the fastening piece D are fastening bolts and nuts.

And the fixed plate A and the fixed plate B are rectangular plates and are respectively fixed on the top of the transformer oil tank and the supporting plate in a horizontal state.

The utility model has the advantages that: the transformer body supporting device is simple in structure, easy to manufacture and convenient to operate, and can meet the requirement that a user additionally installs the supporting device on the transformer body.
