Transportablesubstation integrates high voltage electric equipments, transformers, and low voltage electric equipments into one box or house. It is suitable for business center, resedential district, industrial and mining enterprises, hospital, school, airport, busstation, port and subway, etc. Service Condition 1.Altitude: <=1000m 2.Maximal ambient temperature: +40'C 3.Minimal ambient temperature: -25'C 4.Average temperature in 24 hours: <=35'C 5.Air velocity: <=35m/s 6.Relative humidity: daily average <=95%, monthly average <=90% 7.Horizontal acceleration of earthquake: <=0.4m/s2 8.Vertical acceleration of earthquake: <=0.2m/s2 9.No fire, explosion, severe dirtiness, chemical corrosion or excessive vibration Special condition subjects to users Standard GB/T17467 SD320 Feature 1.Transportable substation is composed of high voltage unit, low voltage unit, relay protection unit and transformer unit. Small volume, reduced cost, reliability, maintainness free and transportability. 2.The casing is made of aluminium alloy plate, stainless steel plate, steel plate or composite board. Aluminium alloy plate is treated by anodic oxidation to enhance anticorrosion and intensity.Steel component is treated by bonderizing. 3.Thermal insulation material, ventilating fan, air conditioner andautomatic controllerare employed to keep required temperature and humidity inside the substation. 4.Oil-immersed (S9, S11, S13, etc.) or dry-type (SCB10, etc.)transformers are optional. In the case of oil-immersed transformer,railings instead of enclosed casing are installed to reinforce cooling. Outer coveringis applied for dry-type transformer. 5.Interlocking device prevents misoperation. 6.AC power supply panel, DC power supply panel, signal panel, protection panel, RTU, carrier machine or optical fiber terminal are installed in relay protection unit. 7.Transformer can be easily pushed in or pulled out from both sides through optional tracks in the unit.
