Iron Tank Type High Voltage Test Reactor , Variable Inductance
Resonant Testing Equipment , Cable Testing
I. Application :
CHX(L,TX) series large capacity& iron tank-type induction
regulation resonance test system is mainly used for AC voltage
withstand or of ex-factory AC voltage withstand test to HV XLPE
cable or other power equipment of 110KV~500KV class, which
Significant advantages is proper for very long continuous working
.This products from Fanke has been subscribed by State Grid
Corporation of China Wuhan High Voltage Research Institute(as per.
The above picture). The specification is 350KV,35A . they are used
for long period stimulating voltage withstand test of super high
voltage cables(type test for EHV XLPE).
Note : Iron Tank Type High Voltage Test Reactor with variable
frequency resonance also can be mady by order .
HV output bushing on the test reactor can be designed to be
horizontal side .
II. Applicable objects
- Field AC voltage withstand and factory AC voltage withstand test of
high voltage power cable of 110KV—500KV.
III. Key features
- Iron box style structure, good heat dispersion, being able to
operating for long time.
- The input power supply capacitor is only 1/Q that of output.
- Weight as1/5~10 of conventional power frequency test transformer
- No transient overvoltage when breakdown the tester
- Wide applicable range, good flexibility of application, large
capacitor range of the
- When breakdown the tested object, the resonant condition is
damaged, shortcircuit current will be reduced to the minimum
automatically, little short-circuit current past on fault point
- Equipped with intelligent measurement and control system, long term
- intelligently and automatically detect, dispense with staff on
- Could be designed as vehicle mounted and equipped with special test
