NON-PARTIAL DISCHARGE POWER-FREQUENCY TESTING TRANSFORMERS    

Usage：

It is used for checking the insulation level of power-frequency voltage of all kinds of insulation materials and electric products, ParTial discharge level It is frequently needed in electric manufacturers, power companies, scientific research institutes and universities. 

Performance：

The 50-1800kV non-partial, discharge power-frequency testing transformers have passed the appraisal of two-ministries. The soilage transformer has obtained the national practical patent. The factory is the unique one to manufacture the sustaining transformer. They are mostly used in Sino-foreign joint venture power transformer manufacturers (shanghai- Areva for example). Main technique capabilities are domestic-leading and keep ahead in the world. 

Characteristics:  

1、Packaged equipment’s can be easily combined. There are adequate series of voltage capacity, and the capability of them is powerful. 
2、Non-partial discharge epoxy insulation pail is successfully invented. It could reduce the partial discharge charge, and it can keep ahead inland. 
3、High quality DQ1 30-30 magnetic particle-directing silicon sheet and 45ompletely mitered sheet are used. Change rate of the wave of products and non-load current is the smallest inland. 
4、Impedance voltage is lower than the determination of the national standard. 
5、Auto-control technique and computer (optical fiber) controlling technique are used. Highly automatic technique results in the strong noise-proof feature. 
6、The reliable fast-electron protecting ins tuitions is used.
