产品特点
Characteristics of the product
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的 1/3-1/5，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：
即可用环网，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 S9 或性能更优的 S11 系列变压器。
Fully insulated, fully sealed, less maintenance, reliable guarantee of personal safety;
Compact structure, the volume is only with the capacity of the European variable 1 / 3-1 / 5, low height;
Can be used sub-box structure, to avoid oil pollution in the transformer tank;
High-side fuse with a full range of protection, greatly reducing costs:
You can use the ring network can also be used for the terminal, the cable can be 200A load current emergency plug;
The cabinet adopts the honeycomb double sandwich composite board, the function of heat insulation and heat dissipation;
Low-voltage side of the installation of electronic phase protection, when the system voltage is not normal, you can quickly break the main switch;
High-pressure side oil-filled load switch or SF6 load switch can be electrically upgraded to lay the foundation for the realization of distribution automation.
The use of oil-immersed S9 or better performance of the S11 series transformers.
