35kV Combined Transformer for Photovoltaic Power Generation (American-Type)

产品简介： 光伏发电作为一种清洁的能源生产方式，在国内外得到迅速的发展，Z口S-ZG-/系列组合式变压器正是为满足日益增长的光伏发电的供电要求，在公司生产35KV组合式变压器基础上，消化吸收国内外的先进技术结合国内需求自行开发的系列产品。该产品是将变压器、负荷开关、高压熔断器安装在变压器的箱体内，利用变压器的绝缘油作为整个产品的绝缘和散热介质，油箱采用全密封结构，具有体积小、重量轻，安装方便等优点。光伏发电用组合式变压器主要分为双绕组和双分裂两种。其中轴向双分裂高压采用轴向分段绕制。低压采用铜箔绕制的方案，低压两个分变可以单独运行、也可以同时运行和并联运行，在光伏发电中得到了广泛应用。

Case Description

Product Features

The ZGS-Z-G modular transformer for photovoltaic power generation consists of three sections: the high-voltage compartment, the transformer body, and the low-voltage compartment, arranged in a “well” or “L” configuration. The high-voltage live parts and high-voltage cables are separated by individual insulating partitions and equipped with electromagnetic locking devices to facilitate installation and maintenance; the high-voltage load switch is a two-position oil-immersed type.
The product features plug-in, full-range protective fuses for protection, and the high-voltage components are housed in the same oil tank as the transformer core.
The transformer core adopts a common-tank structure, with high- and low-voltage bushings arranged on the side for convenient direct connection to high- and low-voltage switchgear. The plug-in fuse is mounted on the top of the tank, effectively reducing the installation footprint. Radiators are installed on the sides of the transformer tank, providing excellent heat dissipation; they can be configured in either an open or a closed design.
No leakage: each tank undergoes a 50 kPa/12-hour sealing test to ensure tight, leak-free containment.
The common-tank, combined-type transformer with dry-type bushings for the high-voltage side offers convenient wiring, supports a greater number of high-voltage incoming and outgoing circuits, and features lower costs.
The equipment enclosure undergoes a rigorous coating process involving iodine-based painting, delivering exceptional outdoor weather resistance and meeting the stringent corrosion protection requirements of harsh environments such as high altitudes and areas with heavy salt spray.
The transformer’s heat-dissipating fins are in direct contact with the ambient air, resulting in excellent heat dissipation.
