Product Details
Product Introduction
The HXXB series variable frequency series resonant withstand voltage device is suitable for AC withstand voltage testing of equipment such as transformers, circuit breakers, switches, GIS systems, cables, bushings, insulators, etc. It has multiple protection functions such as high voltage overvoltage protection, low voltage overcurrent protection, as well as detuning protection, zero position, flashover protection, emergency stop, and undervoltage protection. It can meet the requirements of equipment testing conditions for high voltage and low current, as well as low voltage and high current, and has a wide range of applications.
The frequency adjustment of the HXXB series variable frequency series resonant withstand voltage device is divided into coarse and fine adjustments, and can automatically find the test resonance point to ensure that the resonance frequency does not drift throughout the entire test process; The required power capacity is small, and the power required for the test is only 1/Q of the test capacity; the size is small and the weight is light, which is 1/3-1/5 of the ordinary test device; A resonant power supply is a resonant filtering circuit that can improve the waveform distortion of the output voltage, obtain a good sine waveform, and effectively prevent the breakdown of the test sample by harmonic peaks; Equipped with multiple working modes, using 220V or 380V single-phase power supply for convenient on-site power supply; Multiple ways, modular combination, easy to string and parallel operation, convenient for on-site use.
Product features
The required power capacity is greatly reduced, and the power required for the experiment is only 1/Q of the test capacity.
Ø Small in size and light in weight, usually 1/3-1/5 of a regular testing device.
The resonant power supply is a resonant filtering circuit that can improve the waveform distortion of the output voltage, obtain a good sine waveform, and effectively prevent the breakdown of the test sample by harmonic peaks.
