Description

This PD-free test resonant test system is used for checking the insulation structure and insulation level of

power-frequency voltage of all kinds of insulation materials and electric products (Partial discharge level).

At the same time, it can be also used as PD free power frequency test power supply, such as transformers, 

mutual inductors and lightning arrester.

It is widely needed in electric manufacturers, power companies, scientific research institutes and universities. 

 
Performance

The 50-800kV no-partial discharge power-frequency resonant test systems have passed the appraisal of the

state grid institutes and have obtained the national practical patent. They are widely used in sino-foreign joint

venture power transformer manufacturers. Main technique capabilities are domestic-leading and keep ahead

in this industry.

 
Characteristics

(1)packaged equipment can be easily combined. There are adequate series of voltage capacity, and the capability

of them is powerful.

(2)No-partial discharge epoxy insulation pail is successfully invented. It could reduce the partial discharge charge.

(3)High quality DQ130-30 magnetic particle-directing silicon sheet and 45°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 installation is used.
