Three-Level Testing Equipment - Series Resonance Withstand Voltage Test Device
Product Features:
The adjustment range is 30-300Hz, which complies with the enterprise standard "Regulations for Preventive Tests of Power Equipment" issued by China Southern Power Grid. It not only meets the withstand voltage requirements of high-voltage XLPE cables, but also has the advantages of light weight (each component weighs no more than 30kg) and good mobility, making it suitable for on-site testing.
The resonant reactor and excitation transformer in this device are dry-type epoxy cast, suitable for various cable requirements.
Technical Parameters:
Rated output voltage 0-130 kV (RMS) and below
Output frequency 20-300Hz
Resonant voltage waveform Sine wave, waveform distortion rate ≤1%
Full load working time Continuous working time 60min
System quality factor Under maximum load ≥20
Frequency adjustment fineness 0.1Hz, instability ≤0.01%
Working power supply 220V or 380V
