Specification
CHX-YY hydraulic series resonance test equipment is used for AC voltage withstand test and partial discharge detection of HV electric equipments up to 500kV.It’s especially suitable for CVT calibration test, GIS AC voltage withstand test.
Configurations optional
Two reactors multi-taps designed, enables required power frequency resonant HV output of onsite CVT calibration under 50Hz
Equipped with variable frequency power supply, enables AC voltage withstand test of 100kV-500kV GIS, breakers, mutual inductors, insulators, etc
Used as Power frequency corona-free HV power supply for CVT angular difference and ratio difference calibration
AC voltage withstand test of GIS, switch, CT, breaker and bushing up to 500kV
Hydraulic device lifts up and down the HV test reactor, thus enhancing onsite test frequency
Integrated design of corona free HV test reactor and the excitation transformer saves the onsite test space
Silicone rubber shed as insulation material of the lifting device shortens height of the HV device and optimizes the volume and weight of the device.
The metal base of the lifting device is stable and solid, convenient for transport
