产品概述 Overview

       
       欧式箱式变电站,又称欧式预装式变电站或欧式组合式变电站,简称欧式箱变。它是将高压开关设备、配电变压器和低压开关设备按一定接线方案组合成一体的紧凑型成套配电设备,用于城市高层建筑、城乡建筑、豪华别墅、广场公园、住宅小区、工矿企业及临时用电施工场所,作配电系统中接受和分配电能之用。
       欧式箱变具有结构紧凑、成套性强,运行安全可靠,维护方便,造型美观、便于迁移等优点,与常规土建式变电站相比,同容量的箱式变电站占地面积仅为常规变电站的1/10~1/5,大大减少了设计及施工工作量,减少了建设费用。在配电系统中,可用于环网配电系统,也可用于双电源或放射终端配电系统,是目前城乡变电站建设和改造的新型成套设备。

        European-style box-type substation, also known as European prefabricated substation or European-style combined substation, referred to as European-style box change. It is a compact complete power distribution equipment that combines high-voltage switchgear, distribution transformer and low-voltage switchgear according to a certain wiring scheme. It is used in urban high-rise buildings, urban and rural buildings, luxury villas, square parks, residential quarters, industrial and mining enterprises and Temporary electricity construction site for the acceptance and distribution of electrical energy in the distribution system.

       The European-style box has the advantages of compact structure, strong set, safe and reliable operation, convenient maintenance, beautiful appearance and easy migration. Compared with the conventional civil-based substation, the box-type substation with the same capacity covers only 1/1 of the conventional substation. 10~1/5, greatly reducing the design and construction workload and reducing construction costs. In the power distribution system, it can be used in the ring network power distribution system, and can also be used in the dual power source or radiation terminal power distribution system. It is a new type of equipment for the construction and transformation of urban and rural substations.
