KGXZ CVT Test Voltage Booster Device
Product Introduction
During the calibration of capacitive voltage transformer (CVT), the test frequency must be carried out under the condition of 50Hz. At the same time, the site geographical conditions are complex, and the traditional experimental device has been difficult to meet the requirements of field handling and testing. The resonant boost device used for KGXZ CVT inspection is the first adjustable resonant device used for field calibration in China. It has been widely used in the field calibration of capacitive voltage transformers of 500kV and below in China.

Product Characteristics
1, the output voltage and current waveform is good, the distortion is less than 0.5%;
2, the required power capacity is small, the required power capacity is 1/Q times the test capacity, and the Q value can be 20 ~ 60;
3, there is no need for overvoltage protection, when the test product breakdown, the system is out of tune, the resonant high voltage disappears, the reactor immediately plays a role in limiting the short circuit current, will not aggravate the damage to the test;
4, easy to move, the device is a dry combination series resonant device, composed of excitation transformer and a plurality of resonant reactors, a single component unit small size, light weight, easy to move, suitable for field use;
5, the protection function is perfect, with zero protection (voltage output control knob is not zero, forbid the system to start), overvoltage protection, overcurrent protection, flashover protection and other functions to ensure the reliability of the system.
