Products Details
Overview
This product is developed by absorbing the latest foreign advanced technology and combining with the actual situation in China. It is suitable for new residential areas, green belts, parks, station hotels, construction sites, airports and other places. ZBW-12 prefabricated substation (US substation), suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a substation, metering, compensation control and protection device. This product complies with the following standards: GB/T17467-1998 "High-voltage and low-voltage prefabricated substations", DL/T537-93 "6-35kV box-type substations ordering technical conditions" 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°.
