Specification
CHX-(LYY) hydraulic series resonance test system is used for AC voltage withstand test and partial discharge test of HV equipments up to 500kV, especially for CVT and GIS.
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.
Power frequency corona free HV power supply onsite calibration of CVT angular difference and ratio difference
AC voltage withstand test of GIS, switch, CT, breaker and bushing up to 500kV
Hydraulic device lifts up and down the HV test reactor, enhancing onsite test frequency
Integrated design of corona free HV test reactor and the excitation transformer saves the field 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
