HRYDQ (W) Series of High-voltage Tester of Industrial Frequency Non-partial Discharge for Ultra-light-type Gas-filled-type Transformer
  Introduction of A and B
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. Its also environment-friendly, free of maintenance, long using term, and excellent performances.

As the national new product and patented product, its particularly applicable in partial discharge test of 110kV and 220kV electrical devices. And its the new generation of ideal high-voltage testing devices with two kinds of products, the metal & dielectric shell and the singe Cstage & cascade voltage. It can also be used in the environment of cold and high latitude districts, like altiplanocie

  C. Control Cabinet (Console) and Numerical Control Console for Testing Transformer
As upgrade replacement of high-voltage testing equipment, this kind of testing transformer console applies the automatic control of microcomputer, which is especially useful in automatically controlling system of high-voltage tester of non-partial discharge. It is the first testing console ever made in china, which makes high-voltage testing easier to carry out.

1. Numerical control and manual control
2. Microcomputer to control adjustable voltage speed and output voltage.
3. Multiple over-current and over-voltage protection
4. Automatic discharge voltage recorder
5. Preset operating data through keyboard
6. timer-setting (automatically or manually)
