概述 Overview

箱变结构分为变压器本体、高压室、低压室、检测室、开关操作室和熔断器室六个部分，可
按“目”字型或“品”字型排列。
高压侧采用终端型负荷开关加熔断器保护、熔断器为全范围限流型保护熔断器。
负荷开关和熔断器安装在变压器油箱内，利用变压器的绝缘油作为绝缘介质和散热介质，整
体上具有结构紧凑、散热性能好等优点。
高压侧出线采用高压干式套管支撑桐母线结构，可方便多根电缆线连接。低压侧出线可直接
出线或按用户要求配置低压出线方案。
箱变门采用防风型铰链，箱体上所有的门向外开，开启角度不小于 90°，并设有定位装置。
门都有密封措施，装有门封条，具有缓冲功能，并装有把手，暗门能防雨、防堵、防锈和防
破坏。
箱体为密封防盗结构，采用隐蔽式高强度螺栓及耐油腈橡胶垫圈密封箱盖，整个箱体无外露
可拆卸螺栓。
箱体采用不锈钢板制作，油漆为进口汽车漆，全部采用焗漆方式，防烟雾、防湿热、防霉菌、
户外耐候性能强。光伏发电站所处区域温度低、温差大、湿度大、多风沙，箱变具备合理的
防护结构，防尘结构以及耐低温性能，能满足恶劣环境调节下正常安全运行要求。
The box variable structure is divided into six parts: the transformer body, the high pressure chamber, the low pressure chamber, the detection chamber,
the switch operation room and the fuse chamber, which can be arranged according to the "mesh" type or the "product" type.
The high-voltage side is protected by a terminal type load switch plus a fuse, and the fuse is a full-range current limiting type fuse.
The load switch and the fuse are installed in the transformer oil tank, and the insulating oil of the transformer is used as the insulating medium and the
heat dissipating medium, and the whole has the advantages of compact structure and good heat dissipation performance.
The high-pressure side outlet adopts a high-pressure dry casing to support the Tongan busbar structure, which is convenient for connecting multiple
cable wires. The low-voltage side outlet can be directly routed or configured according to user requirements.
The box changing door adopts a windproof hinge, and all the doors on the box are opened outward, the opening angle is not less than 90 ° , and
a positioning device is provided. The doors are sealed, equipped with door seals, cushioning, and equipped with handles that protect against rain,
blockage, rust and vandal.
The box body is sealed and anti-theft structure. It is sealed with high-strength bolts and oil-resistant rubber gaskets. The whole box has no exposed
detachable bolts.
The box body is made of stainless steel plate, the paint is imported car paint, all adopt the enamel paint method, anti-smoke, anti-humid heat, anti-
mold, outdoor weather resistance. The photovoltaic power station is located in a low temperature zone, large temperature difference, high humidity and
multi-wind sand. The box has reasonable protection structure, dustproof structure and low temperature resistance, which can meet the requirements of
normal and safe operation under harsh environment regulation.
