High-safety resin-making steam injection insulating transformer

Abstract

The invention discloses a high-safety resin-making steam injection insulating transformer, relates to the technical field of insulating transformers, and particularly relates to a high-safety resin-making steam injection insulating transformer which comprises a pouring shell and a bottom frame. A tapping device is installed on the surface of the front side of the pouring shell, and a cushion block is arranged at the bottom of the pouring shell; and an integrated cabinet is integrally arranged on the outer side of the pouring shell, an air cooler is installed on the surface of the bottom frame, the bottom frame is located at the bottom of the integrated cabinet, and rolling wheels are arranged at the bottom of the bottom frame. The high-safety resin-making steam injection insulating transformer is provided with the pouring shell, a resin liquid can be poured through the pouring shell, a resin material is high in safety, non-flammable, low in maintenance cost and free of pollution, the flowing speed of resin can be slowed down in the resin pouring process through a grid layer, meanwhile, air can be conveniently extruded out of air holes in time, bubbles in the resin are avoided, and the safety is reduced.

Description

technical field [0001] The invention relates to the technical field of insulating transformers, in particular to a high-safety resin steam injection insulating transformer. Background technique [0002] With the rapid growth of the national economy and the continuous expansion of the city scale, the 110kV terminal substation will become the focus of urban power. 110kV class transformers can be divided into composite oil-insulated type, oil-immersed type, and SF6 gas-insulated type according to different insulating media. Resin cast insulation transformer is a kind of transformer with reliable operation, safety, flame retardant, fire prevention, no pollution, easy installation, maintenance-free, small size, superior environmental protection performance and mature technology. At present, 35kV and below resin insulated dry-type transformers have been widely used in urban power systems. [0003] During the use of existing insulating transformers, 110kV transformers have always...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-safety synthetic resin steam-injected insulating transformer, which solves the problem that the 110kV class transformer has always been oil-immersed during the use of the existing insulating transformer mentioned in the background art. , its insulating medium is a flammable and explosive product, once a short-circuit accident occurs, it may cause the combustion and explosion of transformer oil, so it has the problem that it cannot be used in densely populated cities and public places with high explosion-proof requirements
