110kV resin casting insulating transformer with three-phase integrated structure

Abstract

The invention discloses a 110kV resin casting insulating transformer with a three-phase integrated structure, which comprises a transformer box body and a sunshade box, a box door is mounted on the front surface of the transformer box body through hinges, a heat dissipation cabinet is mounted on the back surface of the transformer box body, the sunshade box is mounted on the top of the transformer box body, two groups of symmetrically arranged driving boxes are mounted on the inner bottom wall of the transformer box body, a metal rod is mounted at the top of each driving box, a winding box is mounted at the top of each metal rod, two groups of parallelly arranged anti-explosion oil tanks are mounted on the inner bottom wall of the transformer box body, and the anti-explosion oil tanks are located between the two groups of driving boxes. According to the invention, by arranging the sun-shading box, the sun-shading and rain-sheltering device can be specified besides providing sun-shading and rain-sheltering services for the device, the phenomenon that the sun-shading and rain-sheltering device is turned over due to wind blowing is avoided, and the sun-shading and rain-sheltering device can be ensured to continuously and stably provide sun-shading and rain-sheltering services for the transformer box body and the heat dissipation cabinet.

Description

technical field [0001] The invention relates to the technical field of insulating transformers, in particular to a 110kV class resin casting insulating transformer with a three-phase integrated structure. Background technique [0002] With the rapid growth of the national economy and the continuous expansion of the city scale, the development of my country's power grid system has gradually deepened and improved. With the increase in electricity demand, 110KV terminal substations will gradually become the focus of urban power development. In my country, 110KV transformers have always been oil-immersed, but the transformer oil used in oil-immersed transformers is a flammable and explosive substance. Once a short-circuit fault occurs, the level and scope of safety accidents caused are incalculable. It is difficult to popularize places with dense and high explosion-proof requirements, and epoxy resin cast insulation transformer is a transformer with high insulation and no pollutio...

Problems solved by technology

The reinforcing rib of the pressing block increases the creepage distance, reduces the partial discharge, and effectively improves the performance of the transformer.” However, when the arc generated by the internal discharge of the device burns and damages the box, the corresponding explosion-proof protection for the device cannot be taken in time measures that result in a reduction in the safety of the device;
