Model Meaning
Functions and Features
◆Fully insulated, fully sealed, maintenance-free, and reliable to ensure personal safety;
◆Compact structure, the volume is only 1/3-1/5 of the European variable of the same capacity, and the height is low;
◆The sub-box structure can be adopted to avoid the pollution of the oil in the transformer tank;
◆The high-voltage side adopts dual fuse full-range protection, which greatly reduces the cost:
◆It can be used for both ring network and terminal, and the cable head can be plugged and unplugged urgently when the load current is 200A;
◆The box adopts honeycomb double sandwich composite board, which has the function of heat insulation and heat dissipation;
◆Electrical phase loss protector is installed on the low-voltage side, when abnormal voltage occurs in the system, the main input switch can be quickly disconnected;
◆The high-voltage side oil-immersed load switch or SF6 load switch can be upgraded electrically, laying the foundation for the realization of distribution network automation.
◆Using oil-immersed S9 or S11 series transformers with better performance.
Normal use conditions
◆The altitude does not exceed 1000m;
◆Ambient temperature: -35℃~+40℃;
◆Relative humidity: the daily average is not more than 95%, the monthly average is not more than 90%;
◆Installation place: no fire, explosion hazard, chemical corrosive gas and well-ventilated place, the ground inclination angle is not more than 3°.
