Transformer sealing terminal and installation fabrication process thereof

Abstract

The invention discloses a transformer sealing terminal. The transformer sealing terminal comprises an integrated sleeve and a silicon rubber sleeve, wherein the integrated sleeve is arranged on a transformer body, and the silicon rubber sleeve sleeves the integrated sleeve and is screwed on the integrated sleeve by an arc stainless steel sheet, a hook and a butterfly-shaped nut. The invention alsodiscloses an installation fabrication process of the transformer sealing terminal. By the transformer sealing terminal, a sealing cover and a cable sealing thermal contraction pipe in the prior art are removed; with the adoption of the integrated sleeve, the economic cost is reduced; moreover, the sealing terminal structure is high in installation efficiency, has the excellent performance of theft prevention and water prevention and has excellent insulation property, and the service lifetime is prolonged; since a brand-new sealing terminal structure and an installation fabrication mode, the production efficiency and the running reliability are effectively improved, and powerful guarantee is provided for elimination of a potential accident; and after sealing processing, the waterproof performance of a transformer body terminal can be improved, and the running stability of a product is better.

Description

technical field [0001] The invention relates to the technical field of underground transformer processing, in particular to a transformer sealing terminal and its installation and manufacturing process. Background technique [0002] China's urban construction has gone through old city demolition, building renovation and urban network transformation; it has also gone through urban green space and cable power supply, and is now entering the stage of urban beauty aimed at improving streetscape and city appearance. With the continuous deepening of urban ecological design concepts, transformers are gradually buried underground for installation. Underground transformers are designed and developed to meet the requirements of the above fields. A new type of environmentally friendly, energy-saving, and intelligent power transmission and distribution equipment, which is A fully sealed distribution transformer or combination transformer that can be installed underground (or in a pit). ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a transformer sealing terminal and its installation and manufacturing process in view of the current problems. The sealing terminal has a simple structure, effectively improves the installation efficiency of the transformer, has excellent anti-theft, waterproof, excellent insulation performance, and improves the operation of the transformer. The reliability provides a strong guarantee for the elimination of hidden dangers of accidents when the transformer is used in the later stage, and can meet the waterproof and sealing requirements of the low-voltage or high-voltage parts of the underground transformer
