Overview
The box type transformer is divided into three parts: high-voltage chamber, low-voltage chamber and transformer, which can be arranged according to the "eye" type or "character" type.
The internal and external surfaces of the box shall be flat and free of rust, coating falling off and collision damage, and the coating layer shall be firm and uniform without obvious contrast reflection.
The box base and all exposed metal parts shall be subject to anti-corrosion and antirust treatment, and durable protective coating shall be sprayed.
The box top cover is equipped with rainproof sealing cover plate and square rain eaves, and the box top cover with double-layer structure can prevent thermal radiation.
The design size of the box transformer substation door shall match the size of the equipment installed. The box transformer substation door shall be hinged internally, and all doors on the box shall be opened outwards with an opening angle greater than 90 ° .
The box body is made of stainless steel plate, and the paint is imported automobile paint. All the boxes are made of curium paint, which is smoke proof, damp heat proof, mold proof, and has strong outdoor weather resistance. The PV power station is located in an area with low temperature, large temperature difference, high humidity and windy sand. The box transformer substation has reasonable protective structure, dust-proof structure and low temperature resistance, which can meet the requirements for normal and safe operation under harsh environmental conditions.
