  • 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

  1. Two reactors multi-taps designed, enables required power frequency resonant HV output of onsite CVT calibration under 50Hz.

  2. 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

  • Enables installation in a test trailer
