NAYDJ Series Oil type/ Gas type/ Dry type Testing Transformer
Product introduction
NAYDJ Series Oil immersed/ Inflatable / Dry Type Testing Transformer (Short for test transformers), also known as booster, it’s the power station, power supply and distribution systems, and research institutes, and other users basic testing equipment. Used for a variety of electrical products, electrical equipment, insulation materials, etc. which under the specified voltage dielectric strength test, the insulation level of assessment products found to be defective insulation test to measure the ability of withstand over-voltage.
Also called name
High voltage withstand testing equipment; High voltage testing transformer; AC DC high voltage test device; AC/DC hipot test set; Cascade type high voltage testing transformer; Oil-immersed testing transformer; Oil type test transformer; Gas type test transformer, SF6 gas-typed test transformer, SF6 gas-insulated testing transformer; Dry type test transformer
The Characteristics of Series Oil type Testing Transformer
1. Oil type test transformer selected reliable quality and good stability materials.
2. The voltage margin is high, corona sound is small, partial discharge is small.
3. Adopting modern insulating materials, small in size, light in weight
NAYDQ系列充氣式試驗(yàn)變壓器
產(chǎn)品特性
1、NAYDQ系列充氣式試驗(yàn)變壓器體積小，重量輕(比同等級油浸試驗(yàn)變壓器輕40%-65%)。
2、潔凈，無油污，勿需維護(hù)。
3、不受惡劣氣候環(huán)境影響，現(xiàn)場搬運(yùn)勿須靜止即可做試驗(yàn)。
4、絕緣強(qiáng)度明顯高于油浸試驗(yàn)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(dá)1000kVA/1000kV；現(xiàn)場運(yùn)用勿靜止、無油污、免維護(hù)、壽命長、性能指標(biāo)始終良品等優(yōu)點(diǎn)。產(chǎn)品為*新產(chǎn)品和*產(chǎn)品。特別適用于110kV及220kV等級的電力運(yùn)行設(shè)備的局部放電測試。是新一代理想的高壓試驗(yàn)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。

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
