Description

Novel support of transformer high voltage neutral point grounding body installation

Technical Field

The utility model relates to an earthing body installation technical field especially relates to a novel support of transformer high pressure neutral point earthing body installation.

Background

At present, when a direct grounding mode is adopted for a high-voltage neutral point of a transformer, a grounding body is generally connected with an underground main grounding grid of a power plant/power station after being led down along a transformer body, and the grounding body for the high-voltage neutral point of the transformer is fixed by adopting an insulator when being led down, and the insulator is generally arranged on the transformer body. But need destroy the japanning on transformer body surface when adopting above-mentioned mounting means field installation, later stage needs the touch-up paint, and the safe distance of other annexes on main attention grounding body and the transformer body during the installation will satisfy the standard requirement. Especially for foreign projects, if there is a clear requirement, the other parties except the supplier of the transformer body strictly forbid open flame welding on the transformer body, which is not favorable for leading down the installation of the grounding body on the transformer body.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical scheme that its technical problem adopted does:

the utility model provides a novel support of transformer high voltage neutral grounding body installation, include: the bracket main body is arranged on a fireproof wall, or the bracket main body is arranged on an upright post; and the insulator is arranged on the bracket main body and is used for fixing the high-voltage neutral point grounding body of the transformer.

Furthermore, the bracket main body is provided with an opening for installing the insulator.

Furthermore, the support is formed by welding channel steel.

Furthermore, an inclined strut is arranged below the support.

Furthermore, the inclined strut is made of angle steel.

Furthermore, the inclined strut is made of channel steel.

Furthermore, one end of the transformer high-voltage neutral point grounding body is connected with the transformer high-voltage neutral point sleeve, and the other end of the transformer high-voltage neutral point grounding body is connected to the underground and the grounding body of the underground main grounding grid.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the novel bracket for installing the transformer high-voltage neutral point grounding body of the embodiment of the utility model installs the insulator of the transformer high-voltage neutral point grounding body on the novel bracket, and the bracket can be fixed on a fireproof wall near the transformer or a special stand column, so that the transformer body is not required to be damaged, and is not required to be matched with a transformer manufacturer, and the insulator or the insulator installation position is not required to be reserved on the transformer body;

2. the novel bracket installed on the transformer high-voltage neutral point grounding body of the embodiment of the utility model can not damage the paint on the surface of the transformer body during field installation, and can effectively protect the transformer body;

3. the novel bracket installed on the transformer high-voltage neutral point grounding body of the embodiment of the utility model has the advantages of simple material for manufacturing the novel bracket, easy purchase and low price;

4. the utility model discloses the novel support of transformer high voltage neutral point grounding body installation, the size of novel support, the channel steel model, mounting height, the mounted position etc. of adoption all can change according to on-the-spot actual conditions is nimble, and the mounting means is more nimble convenient.
