- 南澳電氣NAYDQ系列充氣式試驗變壓器 產品特性 1、南澳電氣NAYDQ系列充氣式試驗變壓器 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、絕緣強度明顯高于油浸試驗變壓器，電暈極小。 南澳電氣NAYDQ系列充氣式試驗變壓器 采用SF6氣體絕緣技術。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，局部放電量極小，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、性能指標始終良品等優點。產品為國家級新產品和國家級專利產品。特別適用于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。南澳電氣NAYDQ系列充氣式試驗變壓器分金屬體和絕緣筒外殼、單臺與串級電壓兩種類型。特別適用于高寒、（高原）高海撥地區和環境使用。 ?輸出電壓 50kV 100kV 150kV 200kV 250kV 300kV ??輸入電壓 200V 200V 400V 400V 400V 400V ??額定電壓局放量 ≤5pC ≤5pC ≤5pC ≤5pC ≤5pC ≤5pC ??阻抗電壓 ＜8% ＜8% ＜8% ＜10% ＜10% ＜10% ??空載電流 ≤4% ≤4% ≤4% ≤5% ≤5% ≤5% ??波形畸變 ＜3% ＜3% ＜3% ＜3% ＜3% ＜3% ??氣體壓力（Mpa） 0.4 0.4 0.5 0.5 0.5 0.5 NAYDQ Series Gas type Testing Transformer Product characteristics 1,The gas type testing transformer is in small 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 type 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 small 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. As the national new product and patented product, it’s particularly applicable in partial discharge test of 110kV and 220kV electrical devices. And it’s the nanao electric company new generation of ideal high-voltage testing devices with two kinds of products, the metal & dielectric shell and the singe –stage & cascade voltage. It can also be used in the environment of cold and high latitude districts, like altiplanocie Output voltage 50kV 100kV 150kV 200kV 250kV 300kV Input voltage 200V 200V 400V 400V 400V 400V Rated voltage of Partial discharge ≤5pC ≤5pC ≤5pC ≤5pC ≤5pC ≤5pC Impedance voltage ＜8% ＜8% ＜8% ＜10% ＜10% ＜10% No-load current ≤4% ≤4% ≤4% ≤5% ≤5% ≤5% Waveform distortion ＜3% ＜3% ＜3% ＜3% ＜3% ＜3% Air pressure（Mpa） 0.4 0.4 0.5 0.5 0.5 0.5
