NAYDQ系列充氣式試驗變壓器
產品別名
NAYDQ充氣式高電壓試驗變壓器耐壓成套裝置，充氣式試驗變壓器，高電壓試驗變壓器耐壓成套裝置，高電壓試驗變壓器成套裝置，充氣式交直流試驗變壓器，充氣試驗變壓器
產品特性
1、NAYDQ系列充氣式試驗變壓器體積小，重量輕(比同等級油浸試驗變壓器輕40%-65%)。
2、潔凈，無油污，勿需維護。
3、不受惡劣氣候環境影響，現場搬運勿須靜止即可做試驗。
4、緣強度明顯高于油浸試驗變壓器，電暈小。
采用SF6氣體緣技術。油浸試變的換代產品，體積小、重量輕、不受氣候環境變化影響，局部放電量小，單臺容量電壓可達1000kVA/1000kV；現場運用勿靜止、無油污、免維護、壽命長、性能指標良品等優點。產品為新產品和產品。適用于110kV及220kV等級的電力運行設備的局部放電測試。是新一代理想的高壓試驗裝置。產品分金屬體和緣筒外殼、單臺與串級電壓兩種類型。適用于高寒、（高原）高海撥地區和環境使用。

NAYDQ Series Gas te Testing Transformer
Product characteristics
1,The gas te testing transformer is in all size and light weight ( it is lighter 40% to 65% than the same level of oil-immersed testing transformer)
2,Clean, greaseless, do not need maintenance after use
3,Weather-proof , on site testing without standstill
4,The dielectric strength is higher than the oil te testing transformer, and the corona is minimal
Introduction of test transformer
As the only one of applying the SF6 gas-isolated technology, it replaces the oil-immersed transformer by the all volume, light weight, stabilization, and little-current of partial discharge. The voltage capacity of single transformer can even reach 1000kVA/1000kV. It’s also environment-friendly, free of maintenance, long using term, and excellent performances.
