Description

Technical Field

[0001] The utility model specifically relates to an energy storage, boost and current conversion integrated new energy box transformer. Background Art

[0002] The integrated energy storage, boost, and converter new energy packaged transformer is part of a battery energy storage system. It is a prefabricated cabin that integrates a power storage converter (PCS), dry-type transformer, switchgear, and communication power cabinet. As energy storage systems grow in capacity, to address PCS heat dissipation issues, the PCS is often manufactured outdoors and placed directly on the prefabricated cabin chassis. This necessitates the design of a sealed connection channel for the primary connection between the transformer and the PCS.

[0003] The current sealing method used on the joint surfaces of the connecting channel, the box body and the PCS is often to design the joint surfaces of the box body, PCS and the sealing channel into a circle of vertical planes, affix a sealing strip on this vertical plane, and directly drill holes in the sealing strip to tighten bolts. This causes excessive compression of the sealing strip, and the sealing strip is exposed, which is prone to aging and failure in harsh environments. At the same time, water is easily accumulated on the upper sealing strip, causing water seepage and leakage in the sealing channel, which will seriously lead to short-circuit accidents. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to provide an integrated energy storage, boost and current conversion new energy box transformer that can prevent rainwater from accumulating and infiltrating, while also protecting the side sealing strips from long-term exposure to the sun, which can accelerate aging of the side sealing strips.

[0005] According to the utility model, an integrated energy storage, boost and conversion new energy box transformer includes a PCS energy storage converter and a box transformer body. A channel shell is provided between the PCS energy storage converter and the box transformer body. One side of the channel shell is placed in the box transformer body, and the other side of the channel shell is provided with a vertical flange. The top of the vertical flange is provided with an oblique outer flange.

A guide groove outer flange is also provided on the guide groove. The guide groove outer flange is placed on the outer surface of the vertical flange, and a side sealing strip is provided between the guide groove outer flange and the vertical flange.

[0006] Specifically, the top end of the channel shell is provided with a top cover plate and an inner flange, the inner flange is placed on the bottom surface of the top cover plate, and a top sealing strip is provided at the contact point between the inner flange and the bottom surface of the top cover plate.

[0007] Specifically, the top cover plate is provided with a top cover plate flange, and the upper surface of the channel shell is provided with welding studs, which pass through the top cover plate flange and are welded to the top cover plate flange.

[0008] Specifically, the channel shell is respectively provided with a left sealing plate, a bottom sealing plate and a right sealing plate.
