YB□-12/0.4型预装式变电站（欧式箱变）

YB□-12/0.4型预装式变电站（欧式箱变），由高压开关设备、变压器本体和低压开关设备在工厂内预先组装在箱壳内，一般结构为品字排列或目字排列，变压器可根据需要选用油浸式变压器或干式变压器。应用于三相交流50Hz、7.2kV～40.5kV的系统中，作为接受和分配电能之用。适用于居民配电工程、工商业配电工程、城区或者居民区分布式光伏项目。

The prefabricated substation (European-style box-type substation) is assembled in a factory with high-voltage switchgear, transformer body and low-voltage switchgear pre-installed in the enclosure. The general structure is arranged in the form of a "T" or "Y", and the transformer can be selected as oil-immersed or dry-type according to requirements. It is used in 50Hz three-phase AC systems with voltages ranging from 7.2kV to 40.5kV, for the purpose of receiving and distributing electrical energy. It is suitable for residential distribution projects, industrial and commercial distribution projects as well as distributed photovoltaic projects in urban or residential areas.
