A high-safety oil-immersed transformer that ensures stable and normal sound and temperature

Abstract

The invention discloses a high-safety oil-immersed transformer that ensures stable and normal sound and temperature. It includes a transformer shell, a support base is installed on the bottom of the transformer shell through bolts, and a sealing top cover is installed on the top of the transformer shell through a connecting block. A support plate is installed under the sealing top cover through bolts, a support column is installed under the support plate through bolts, a compression plate is installed under the support column through bolts, and a circuit integration box is installed on the surface of the compression plate through bolts. A transformer is installed under the pressing plate through bolts, a protective casing is wrapped around the outside of the transformer, a placement plate is welded inside the transformer casing, and a mounting plate is nested on the surface of the transformer casing. The present invention solves the existing oil-immersed transformer problems of poor heat dissipation, high noise during operation, and the risk of short circuit leakage due to internal high temperature by providing heat dissipation plates, heat dissipation filling, air outlets and diversion grooves.

Description

technical field [0001] The invention relates to the field of oil-immersed transformers, in particular to a high-safety oil-immersed transformer that ensures stable and normal sound and temperature. Background technique [0002] Oil-immersed transformers are widely used in the market due to their low production cost and good stability. However, during the use of the existing oil-immersed transformers, there are two problems as follows: one is that after the oil-immersed transformers have been used for a long time, the insulating oil in the oil-immersed transformers is prone to subsidence for a long time without moving. As a result, the density of the insulating oil on the upper layer is small, and the density of the insulating oil on the bottom layer is relatively high, which makes the heat dissipation of the oil-immersed transformer uneven, which leads to the local temperature of the oil-immersed transformer being too high, which is very prone to fire, resulting in the oil-i...
