户外预装式变电站（欧式）功能及特点 Functions and characteristics

◆全绝缘、全密封、免少维护、可靠保证人身安全；

◆结构紧凑、体积仅为同容量欧变1/3-1/5的高度低；

◆可采用分箱式结构，避免变压器油箱内油的污染；

◆高压侧采用双熔丝全范围保护，大大降低成本：

◆既可用于环网，也可用于终端，电缆头可在200A负荷电流时紧急插拔；

◆箱体采用蜂窝式双夹层复合板，隔温又散热的功能；

◆低压侧加装电子缺相保护器，当系统内出现不正常电压时，可快速分断主进开关；

◆高压侧油浸式负荷开关或SF6负荷开关， 可电动升级， 为实现配网自动化打下基础。

◆采用油浸式或性能更优的SF11系列变压器。

◆Fully insulated, fully sealed, less maintenance, reliable guarantee of personal safety;

◆compact structure, volume is only 1/3-1/5 of the same capacity Euclidean height is low;

◆Sub-box structure can be adopted to avoid oil pollution in transformer tank.

◆High voltage side adopts full range protection with double fuses, which greatly reduces the cost.

◆It can be used not only in loop network, but also in terminal. The cable head can be plugged in and out in case of 200A load current.

◆The box body adopts honeycomb double sandwich composite board, which has the functions of heat insulation and heat dissipation.

◆The low voltage side is equipped with an electronic phase-gap protector. When abnormal voltage occurs in the system, the main switch can be quickly interrupted.

◆High-voltage side oil-immersed load switch or SF6 load switch can be upgraded electronically, laying the foundation for realizing distribution automation.

◆Use oil-immersed or better performance SF11 series transformer.
