BSXZ-F CVT series resonant boost device

Product Introduction

When calibrating a capacitive voltage transformer (CVT), the test frequency must be conducted at 50Hz. At the same time, the geographical conditions on site are complex, and traditional experimental devices are difficult to meet the requirements of on-site handling and testing. The BSXZ-F type tunable resonant boost device is the first adjustable resonant device used for on-site calibration in China, and has been widely used for on-site calibration of capacitive voltage transformers of 500kV and below in China.

Product Features

1. The output voltage and current waveform is good, with distortion less than 0.5%.

2. A small capacitance is required, and the required power supply capacity is 1/Q times the test capacity, with a Q value of 20-60.

3. No overvoltage protection is required. When the test sample breaks down, the system loses resonance, the resonant high voltage disappears, and the reactor immediately acts to limit the short-circuit current, without exacerbating the damage to the test sample.

4. Easy to move on site, this device is a dry-type combined series resonant device consisting of an excitation transformer and multiple resonant reactors. Each individual unit has a small volume and light weight.

5. The protection function is complete, with zero position protection (when the voltage output control knob is not in zero position, the system is prohibited from starting), overvoltage protection, overcurrent protection, flashover protection and other functions, ensuring the reliability of the system.
