wind power generation substation
?Structural features
?1. Fully insulated, sealed, low maintenance, to ensure your personal safety;
?2. Compact, only with the volume capacity of the EU becomes 1 / 3-1 / 5; height of only 1.5 meters, do not block the line of sight;
?3. binned structure, to avoid contamination of the transformer oil tank;
?4. The high-pressure side of the full range of dual fuse protection, greatly reduce the cost;
?5. either by the ring, the terminal can also be used, the cable head can be removed in an emergency when the load current is 200A;
?6. box with dual cellular sandwich composite panels, compartment temperature but also cooling.
?7. A low-pressure side can be equipped with under?voltage controller when an abnormal voltage is present within the system, it can quickly cut the low-pressure side of the load;
?8. The high-pressure side of the oil-immersed load switch or SF6 load switch, can be automatically upgraded to achieve distribution automation foundation.
?use
?Widely used in urban power grids, residential quarters and other public places, as well as factories, hotels, airports, railways, docks, highways and other indoor and outdoor venues.
?Normal conditions of use
?1. Altitude less than 1000m;
?2. Ambient temperature: -35 ℃ ~ + 40 ℃;
?3. Relative humidity: daily average of not more than 95%, on a draw is not greater than 90%;
?4. Installation place: no fire, explosion, chemical corrosive gas and well-ventilated place, the ground angle of not more than 3 °.
?Fuses
?American substation high voltage side by the back-up protection fuse and plug-in fuse in series to provide a full range of protection, the principle is simple, economical and reliable; backup protection fuses oil-immersed voltage current-limiting fuses, breaking capacity, only inside the transformer failure when the action plug-in fuse built Unika fuse.
