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

Introduction:
It is a kind of contact ratio autotransformer which
can adjust load voltage within rated voltage. This
series of products are well designed because they
adopt UK imported A brush for voltage adjusting
parts. With strict quality control during production,
this kind of device is very small, light, with low
waveform distortion, low noise, and low temperature.
Technical parameter:
Capacity: 5、10、16、20、25、30、40、50、80、100、125、160……1500kVA
Maximum of phase of input and output:
Single phase: 220/0-250V，380V/0-430V
Three-phase: 380V/0-430（650）V
Notes: Direct output would be high voltage if
not set.

Current
amplifier which thermally stabilizes electrical
devices is a kind of current source for testing
use. For example, it can be used as low-voltage
super-current source in motion stability test and
temperature rising test of air circuit breaker,
contactor, relay, and bus-bar. In addition, it can
also be used as check current source of current
transformer. Current amplifier, no matter if it’s
the single phase or the three phase, the AC current
or the DC current, is consisted of super-current
generator (transformer), regulator and controller.
Output : AC3-12V、50-50000A
DC10-20V、50-50000A
Working hour:
For rated voltage output, then working hour would
be 2.5 minutes.
For 1/4 of rated voltage output, then working
hour would be used in a long time.
