产品概述  Overview

组合式变压器，是将升压变压器器身、开关设备、熔断器、分接开关及相应辅助设备进行组合的变压器，高压开关、熔断器均安装在油箱内，整体外形尺寸较小，其结构形式与90 年代从美国引进的箱变相似，按产品结构及元件 配置可分为两种，一种是全绝缘分箱式产品，一种是高压采用干式套管出线的共箱式产品。

A combination transformer is a transformer that combines the body of a step-up transformer, switchgear, fuse, tap changer, and corresponding auxiliary equipment. The highvoltage switch and fuse are all installed in the oil tank, with a smaller overall size. Its structural form is similar to the box transformer introduced from the United States in the 1990s, and can be divided into two types according to product structure and component configuration. One is a fully insulated box type product, One type is a common box type product that uses dry casing for high-voltage output.
