Product Introduction
The UHV AC Resonant Test System for Cable is a portable frequency conversion resonance voltage test device designed for domestic cable testing. It adopts a special SPWM digital waveform generator chip and advanced IPM modules, features a dry epoxy cast reactor, and utilizes orthogonal asynchronous stationary carrier modulation for stable and efficient performance.
The main functions and technical features of the frequency series resonant test device are as follows:
1. The device has over-voltage, over-current, zero start, system detuning and flash-over protection function. The over-voltage and over-current protection value can be set according to user's needs, and the flash-over protection action to protect the product.
2. Small volume, light weight, very suitable for the operation of the people on the spot.
3. The device has three working modes, which is convenient for users to choose flexibly according to the field conditions and improve the test speed. The working modes are: full automatic, manual and automatic tuning manual boost mode.
4. The data can be stored and printed in different places. The data number is numbered is convenient to help the user to identify and find the data.
5. When the device automatically sweeps the frequency, the starting point of frequency can be set arbitrarily in the specified range. Meanwhile, the LCD screen displays the scanning curve, which is convenient for users to directlyunderstand whether the resonance point is found .
6. Using the DSP technology, it can easily increase and decrease the function and upgrade according to the needs of the user, and also make the human-computer exchange interface more humanized.
