ETCXB-H series CVT inspection resonant boost device

Product Introduction

The ETCXB-H series CVT inspection resonant boosting device is used for boosting various types of CVT calibration at voltage levels of 35kV, 66kV, 110kV, 220kV, 330kV, and 500kV. The CVT inspection uses a resonant boost deviceSeries ResonanceThe principle of the device adopts the technique of stepless manual sensing and the series connection of energy-saving resistors, which greatly reduces the required power supply, test equipment volume and weight, and simplifies wiring operation for on-site testing. It is the preferred device for power metering and high-voltage testing majors.
The output voltage and current waveform of the resonant boost device used for CVT inspection is good, with distortion less than 0.5%;
The resonant boost device used for CVT inspection requires a small capacitance. The required power capacity is 1/Q times the test capacity, and the Q value can reach 20-60;
The resonant boost device used for CVT inspection does not require overvoltage protection. 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;

Product characteristics

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 limits the short-circuit current without exacerbating the damage to the test sample
4. Easy to move on site, this device is a dry-type combination series resonant device consisting of an excitation transformer and multiple resonant reactors. Each individual unit has a small volume and light weight, making it easy to move and suitable for on-site use
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
