Compact Substation Transformer Applications:
· The prefabricated compact substation is a compact complete power distribution equipment that integrates low-voltage/medium-voltage switchgear, distribution transformers, electric energy metering devices and reactive power compensation devices in one box, which is convenient for transportation and installation.
· Compact substations are small in size and are widely used in power distribution systems with rated voltages ranging from 11kV to 40.5kV. It can be installed outdoors with a small footprint. The altitude above sea level does not exceed 1000m, if special custom-made transformers and low-voltage components are used, it can reach 4000m, the vertical inclination is not more than 5°, no violent vibration, no impact.
· Compact substations are suitable for residential quarters, urban public utilities, building electricity, etc. Users can choose compact transformers according to different load levels. No conductive dust, no explosion hazard, no corrosive metal and electrical components in the gas place, and the outdoor wind speed does not exceed 35m/s.
· The shell part is generally made of galvanized metal clad steel, which has good anti-corrosion performance and is guaranteed not to rust for 20 years. The operation of the equipment is not affected by climate and environmental pollution, and can guarantee normal operation in harsh environments ranging from -40°C to +40°C. The air humidity is not more than 90% (+25°C).
