Solar Photovoltaic and Wind Power Step-up Substation
1.Product Overview `
Solar Photovoltaic and Wind Power Step-up Substation (New energy box type substation) is a whole set of substation including transformer, HV part LV part and other auxiliary equipment in a common enclosure and passed the type test. The structure of product combines the advantages of European style substation and American style substation. It’s a new step up equipment specially designed for the particularity of wind power and photovoltaic, which has the advantages of strong complete set, easy for installation, short construction period, low operating cost, high structural strength, excellent anticorrosive property, environment friendly and energy saving etc..
2.Product Features
1)The solar photovoltaic and wind power step up prefabricated substations include LV incoming cubicle, transformer and HV incoming cubicle which are independently installed in three compartments, are arranged into coupled “F” type. The LV compartment is equipped with remote device and power supply transformer to realize the remote control and self power supply. 35kV HV switch-disconnections and fuse-combination units placed in two different rooms solves the problem that when to replace the switch, fuse or arc-chute, the whole line need to be shut down.
2)The solar photovoltaic and wind power step up pad-mounted substations includes the LV incoming cubicle, transformer and the HV load switch and fuse installed inside the transformer tank. The arrangement of the whole set is divided into "L" type and coupled "F" type. The LV compartment is equipped with remote device and power supply transformer to realize the remote control and self power supply. As there is no transformer room, the whole set covers relatively less area, less cost and reduces the investment of user.
3)Adopted the radiator installed in open, achieved the heat dissipating performance of fully air natural ventilation which saves the power loss caused by air forced ventilation, avoids the defect of over temperature trip caused by the unreliable performance of fans in air forced ventilation, makes all the live parts fully sealed in the substation, and realizes the dust-proof.
4)"Five-prevention" functions are completed, easy operation and maintenance, and can be checked and maintained in rainy days.
3. Operation environment
1) Altitude: ≤1000 meters.
2) Ambient temperature: Maximum +40oC, Minimum -45oC.
3) Relative humidity: ≤90% (+25 oC).
4) Max. Outdoor wind speed 45m/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) Metal enclosure and stainless steel enclosure could be customized.
2) Fully insulation, semi-insulation, vacuum load switch, solid insulation ring, etc. can be selected as HV parts of transformer parts according to the customer's requirements.
3) Prefabricated substation can select oil-immersed transformer, dry type transformer and amorphous alloy transformer, while the combined substation can only use oil immersed transformer.
4) LV circuit can be changed as per customer's requirements.
5) The outline arrangement can be reasonably optimized according to different solutions, usually divided into open type and fully sealed type.
