Product details
■ Product Overview
This product is developed by absorbing new foreign technologies and combining them with the actual situation in China. The entire product has the characteristics of small size, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, and full protection. Suitable for new residential areas, green belts, parks, stations, hotels, construction sites, airports, and other places.
ZGS □ -12/630-10 series American prefabricated box type 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 "Technical Conditions for Ordering 6-35kV Box type Substations"
■ Model meaning
■ Function and Features
Fully insulated, fully sealed, maintenance free, and reliable to ensure personal safety;
Compact structure, with a volume only 1/3-1/5 of the same capacity European transformer, and low height;
A split box structure can be used to avoid oil pollution in the transformer oil tank;
The high-voltage side adopts dual fuse full range protection, greatly reducing costs;
It can be used for both ring network and terminal, and the cable head can be urgently plugged and unplugged when the load current is 200A;
The box is made of honeycomb double layered composite board, which has the functions of insulation and heat dissipation;
Install an electronic phase loss protector on the low voltage side, which can quickly disconnect the main switch when abnormal voltage occurs in the system;
High voltage oil immersed load switches or SF6 load switches can be electrically upgraded, laying the foundation for achieving distribution network automation.
Adopt oil immersed S9 or S11 series transformers with better performance.
■ Normal usage conditions
Altitude not exceeding 1000m;
Environmental temperature: -35 ℃~+40 ℃;
Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;
Installation location: A place without fire, explosion hazards, chemical corrosive gases, and good ventilation, with a ground inclination angle of no more than 3 degrees.
