產(chǎn)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(huán)境影響，現(xiàn)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。
采用SF6氣體絕緣技術(shù)。油浸試變的換代產(chǎn)品，體積小、重量輕、不受氣候環(huán)境變化影響，局部放電量極小，單臺容量電壓可達1000kVA/1000kV；現(xiàn)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(yōu)點。產(chǎn)品特別適用于110kV及220kV等級的電力運行設(shè)備的局部放電測試。是新一代理想的高壓試驗裝置。產(chǎn)品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(qū)和環(huán)境使用。

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
