Prefabricated Substation or Prefabricated Transformer
1.Product Overview
Prefabricated substation (Box type substation) is also known as European style box transformer or Pre-installed substation. It is a set of high-voltage switchgear, distribution transformers and low voltage power distribution equipment connected in one of the factory indoor, outdoor compact type distribution equipment according to a certain wiring diagram. It organically combined together the step-down transformer, low voltage power distribution, and other functions in a moisture proof rust-proof, dustproof, rat-proof, fire prevention, guard against theft, thermal insulation, fully enclosed, movable outdoor box. It is especially suitable for city network construction and retrofit, which is a new substation after the rise of civil substation. Pre-installed substation is suitable for mines, factory enterprises, oil and gas fields and wind power stations, which replaces the original civil distribution room and distribution station. It becomes a new complete set of substation and distribution devices.
2. Product Features
1) Compact structure, small size, safe and reliable operation, easy for maintenance and removable.
2) Suitable for the lighting and power system of streets, highways, bridges, tunnels, parking lot residential areas and tourist attractions, especially for urban grid transformation.
3) Power supply safe and reliable. Can provide perfect mechanical or electrical linkage, meet the requirement of “five-prevention”, and ensure the safety of the person.
4) Enclosure material is various and the design is beautiful. Under the premise that guarantees the power supply reliability, we can easily harmonize with the surrounding environment by selecting the shell color, which is especially suitable for urban construction.
5) The transformer is mainly ventilated with natural ventilation, and when the temperature of the transformer room exceeds the set temperature, the axial fan on the top automatically starts to control the temperature.
6) The prefabricated transformer substation can be customized according to the user's requirement since each functional unit is independent. Therefore the selection range is large and the market adaptability is strong.
7) High degree of automation. Protection system uses substation microcomputer integrated automation devices, which can realize "four control" namely, telemetry, remote communication, remote control, remote regulating. Each unit has independent operation function and complete relay protection function. It can set the operating parameters remotely, control the humidity and temperature in the box, and remote smoke alarm, which meets the requirements of the unattended. Image remote monitoring is also possible if required.
3. Operation environment
1) Altitude: ≤1000 meters.
2) Ambient temperature: Maximum +40ºC, Minimum -25ºC.
3) Relative humidity: ≤90% (+25 ºC).
4) Max. Outdoor wind speed 35m/s;
5) Max Ground ramp degree: ≤3°.
6) Seismic level: ≤0.3m/s2 at horizontal direction and ≤0.15m/s2 at vertical direction.
7) Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
8) If the application environment is different from the above standard conditions, please contact for customized designs.
4. Type Selection Instruction
1) Non-metallic surfaces, metal enclosure, wood enclosure and stainless steel enclosure can be chooses by customer's requirements.
2) Fully insulation, semi-insulation vacuum load switch solid insulation ring, etc. can be selected as transformer H.V parts according to customer's requirements.
3) Oil-immersed transformer, dry type transformer and amorphous alloy transformer can be selected as per customer's requirements.
4) We have LV circuit general configuration, and can be changed as per customer's requirements.
5) Equipment capacitance compensation can be divided into intelligent capacitance and common capacitor. The capacity can be changed as per customer's requirements
6) Equipment arrangement usually divided into coupled "F" type and "O"+ reversed "E” type. Special plan can be optimized as per customer's requirement.
