Resonant Test Device mainly aimed at consumers 10kV,35kVcable,110kV,under compression experiment design and manufacture of substation exchanges.
Variable Frequency Resonance test set makes the reactor and tested capacitor in resonant by adjusting the frequency of the power source, to get high voltage and heavy current from measured equipment. Now it is a new method and trend for high voltage test and widely used.
Resonant Test Device is mainly composed of Variable Frequency Power,Exciting Transformers,Reactors, Capacitive Dividers.
FM resonant device main function and its technical characteristics:
1, Device high accuracy.with, over-current, zero start up, system detuning (flash) protection function, treasure-the over pressure over-current protection value can according to the needs of user setting, try product flash when winding treasure-the protection movement and can flash, flash winding down for the test voltage value are analyzed.
2, The whole device, the largest piece very light weight not more than 40kg and convenient for field use.
3, Device has three working mode, user-friendly according to the site condition flexible choice, improve test speed. Working mode for: automatic mode and manual mode, automatic tuning manual pressurization mode.
4, Different print data can be stored and the data Numbers is, stock, easy to help users digital identification and searching.
5, Device automatic frequency sweep frequency starting point when in the specified scope set arbitrary, sweep frequency direction can choose, while upward and downward LCD big screen display scanning curve, be convenient for the user intuitive understanding whether find resonant point.
6, Adopted DSP platform technology, can conveniently according to the needs of user increase or decrease function and upgrade, but also makes the man-computer exchange interface humanized.
