This device will be in resonant state by adjusting the inductance value of the inductor or the working frequency of the whole system or both methods. Adjust the frequency of the excitation transformer to the required frequency, then adjust the inductance of the inductor according the inductance value of the measured equipment, make the system in resonant, and generate high voltage, if the resonance point is deflected during the voltage boosting process, can regulate the frequency to correctly find the resonance point to ensure the high Q value, in order to farthest lessen the volume and weight of the measured equipment and power capacity.
1. Device with over-voltage, over flow, zero start-up and loss of harmonic flashover protection, overvoltage and current protection value can according to user needs setting,flashover protection action and can remember the flashover voltage value, for experimental analysis.
2. The whole unit weight is very light, the maximum not more than 40kg, to facilitate the use of the scene.
3. The device has three modes of operation, which is convenient for users to choose flexibly according to the field condition, and the test speed is improved.
4. Working mode is: automatic mode, manual mode, automatic tuning manual boost mode.
5. Can store and print data in different places, the data stored in the number is digital, easy to help users to identify and find.
6. Device automatic sweep frequency starting point can be within the scope of the provisions set arbitrarily, sweep direction can be upward, downward selection, also the large screen liquid crystal display scanning curve, convenient user intuitive understand whether find resonance point.
