A 110kV Class Resin Casting Insulation Transformer with Three-phase Integrated Structure

Abstract

The invention discloses a 110kV class resin cast insulation transformer with a three-phase integrated structure, which comprises a transformer box body and a sunshade box. A heat dissipation cabinet is installed, a sunshade box is installed on the top of the transformer box, two sets of symmetrically arranged drive boxes are installed on the inner bottom wall of the transformer box, and a metal rod is installed on the top of the drive box. A winding box is installed on the top of the rod, and two sets of explosion-proof oil tanks arranged in parallel are installed on the inner bottom wall of the transformer box, and the explosion-proof oil tanks are located in the middle of the two sets of drive boxes. The present invention is provided with a sunshade box, in addition to providing sunshade and rain-shielding services for the device, it can also regulate the sunshade and rain-shielding device, avoiding the phenomenon that the sun-shading and rain-shielding device is overturned due to wind blowing, and ensuring that the sun-shading and rain-shielding device can Provide continuous and stable sunshade and rain protection services for transformer boxes and cooling cabinets.

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;
