產品概述 Overview
組合式變壓器，是將升壓變壓器器身、開關設備、熔斷器、分接開關及相應輔助設備進行組合的變壓器，高壓開關、熔斷器均安裝在油箱內，整體外形尺寸較小，其結構形式與90 年代從美國引進的箱變相似，按產品結構及元件 配置可分為兩種，一種是全絕緣分箱式產品，一種是高壓采用干式套管出線的共箱式產品。
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.
