Basic Info.
Product Description
European-type prefabricated substation has features of high reliability, attractive appearance, modular structure and convenient installation and operation and is mainly applied to 10kV distribution networks and other public places, such as industrial and mining establishments, airports, railway stations, ports, expressways, undergrounds, etc.
Product characteristics:
1. The casing adopts advanced technology in China and new materials (aluminum alloy plate/ steel plate or composite plate) and could resist heat, dust, dampness and small animals.
2. The casing of the transformer chamber adopts maze plate structure for realizing attractive appearance, convenient disassembly and sound ventilation.
3. The box skeleton adopts channel steel and steel angle to ensure adequate mechanical strength, the internal and external surfaces of each component accepts antiseptic treatment to prevent corrosion. The top cover adopts two-layer structure to prevent thermal radiation.
High-voltage unit
TPS Ring Main Unit has high voltage switches, all-insulation protection and integrated SF6 gas cell and could guarantee personal and equipment safety through passing internal combustion arc test and zero gauge pressure test. It is also provided with reliable mechanical interlocking and faulty operation prevention functions and features small size, light weight, long service life and 30-year maintenance-free performance. Home-made XGN-12 SF6 Ring Main Unit (single gas bag) can also be adopted. The load switches are sealed in the all-insulation SF6 gas box that adopts imported aluminized zinc sheet and are riveted with numerically-controlled machine tools.
Optional functions
1) Electric control: A low-voltage control box and electrically operated mechanism can be installed to realize electric control of switches and distribution network automation.
2) Fault display: Through the panel-type LCD fault display. The faults, such as short circuit or grounding, can be displayed and located exactly and thus the equipment repair and maintenance efficiency can be enhanced greatly.
Transformer unit
S9 or S11 full-sealed oil-immersed transformer is adopted, The elbow cable head and 200A adopted at high-tension side to realize all-insulation connection, featuring no leakage, maintenance-free, safety and reliability. Two kinds of solid-cast transformers can also be adopted:
SCG solid-cast platinum-winded transformer with high mechanical strength, low partial discharge volume, flame retardance, explosion protection, no environmental pollution, moisture-free winding and low loss.
SGB solid-cast transformer adopting NOMEX paper insulation system. It is flame retardant, pollution-free, fire resistant, environment-friendly and boasts long service life, reclamation, high mechanical strength, short circuit resistance, low loss, low noise, safe and reliable operation, etc.
Low-voltage unit
The low-voltage switches can adopt circuit breakers as required and could provide individualized metering and reactive compensation devices as required.
The low-voltage unit adopts draw-out modular design to realize simple layout, clear functions and convenient installation and repair.
