The gas cabinet adopts cable connectors, bus connectors, voltage transformers and other high-voltage components all adopt the external plug-in structure of the gas cabinet. It is especially suitable for large and medium-sized cities with tight land resources and major projects of medium pressure system or transformer distribution power station with harsh environment such as high altitude, high salt spray and high humidity, and it is more economical to use in countries and regions with carbon emission requirements.
Ring cabinet adopts partial N2 or pure N2 insulation, no barrier discharge insulation partition between phase, no insulation aging failure risk, zero gauge pressure is low functional pressure, delay the time of equipment leakage to atmospheric pressure, ensure the rated insulation level of equipment, and arrange power failure inspection and maintenance time, increase the reliability of equipment operation. Compact, easy to expand, with a high maintenance, safety. |
