组合式变压器(美式箱变)

一、概述Summary

组合式变压器(美式箱变)是将高压开关、变压器和低压配电设备按一定的接线方案组合在箱体内小型化配电设备。作为高压配电计量,补偿控制和保护装置,高压侧装有四工位或二工位负荷开关,后备保护熔断器及插入式熔断器,低压侧可按用于要求装设控制电器、配电电器、补偿装置及电能计量表等,本公司生产的组合式变压器具有损耗低、噪音低、安全可靠、体积小、外形美观、安装周期短等优点。

Combined transformer (American box) is the high voltage switch, transformer and low voltage power distribution equipment according to a certain terminal portfolio in the box body, miniaturization of power distribution equipment. As a high voltage distribution measurement, compensation control and protection device, high voltage side is provided with four station or two position load switch, and insert backup fuse according to the requirements, the low-voltage side for the installation of control electrical appliances, electrical distribution, compensation device and electric energy meter. The company's combined transformer with advantages of low loss, low noise, safety and reliability, small size, beautiful appearance, and installation short cycle.
