High-voltage test system HVTF1

for electrical networks

The AC withstand voltage test device is suitable for AC withstand voltage test of transformers, circuit breakers, switches, GIS systems, cables, bushings, insulators and other equipment. With high voltage overvoltage protection, low voltage overcurrent protection, as well as detuning protection, zero position, flashover protection, emergency shutdown, undervoltage protection and other multiple protection functions. It can meet the test requirements of high voltage and low current equipment, and meet the test requirements of low voltage and high current equipment. It has a wide range of application. The frequency adjustment of the AC withstand voltage test device is divided into coarse adjustment and fine adjustment, and the test resonance point can be automatically found to ensure that the resonance frequency does not drift during the whole test process; the required power supply capacity is small, and the power supply required for the test is only tested. The capacity is 1/Q; the volume is small and the weight is light, which is 1/3-1/5 of the common test device; the resonant power supply is a resonant filter circuit, which can improve the waveform distortion of the output voltage and obtain a good sinusoidal waveform, effectively preventing Harmonic peak to the wrong breakdown of the test sample; with a variety of working modes, 220V or 380V single-phase power supply, convenient on-site power; multi-mode, modular combination, can be combined and easy to operate, convenient for on-site use.
