Product Description
Inexhaustible clean energy sources of wind energy and solar energy have been rapidly developing, therefore we developed Solar Photovoltaic and Wind Power Step-up Substation. It is a whole set of substation including transformer, HV part LV part and other auxiliary equipment in a common enclosure passed the type test. The structure of product combines the advantages of European style substation and American style substation. Its new step up equipment specially designed for the particularity with the advantages of strong complete set, easy for installation, short construction period, low operating cost, high structural strength, excellent anticorrosive property, environment friendly and so on.
Main Characteristics
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 needs 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 proof" functions completed, easy to make operation and maintenance, meeting the requirement of check and maintenance in rainy days.
