(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. 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 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 |

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) |
