HDXZ-162kVA/54kV Variable Frequency AC Resonant Test System is applied for AC dielectric withstand test for electric equipment.
The system is mainly composed of following parts:variable frequency control power supply,exciting transformer,reactor and capacitive divider.
1. 10kV/300mm2 cable 3km AC withstand voltage test, capacitance ≤1.1265uF, test frequency 30-300Hz, test voltage 22kV, test time 5min.
2. 35kV/300mm2 cable 1.5km AC withstand voltage test, capacitance ≤0.2917uF, test frequency 30-300Hz, test voltage 52kV, test time 60min.
Features
● With the function of over-voltage, over-current, zero-start, system detune (flashover) protection. Over-voltage, over-current protection value can be set accordingly to user’ need. Flashover protection action when the test object
● flash over and tester records the flashover voltage value for testing analyze.
● Small volume, light weight, very suitable for the operation people on the spot.
● There are three kinds of working modes, which is convenient for user choosing according to on-site condition. Working modes : Automatic mode, Manual mode, Automatic tuning manual boost mode.
● Data can be stored and printed in different places, and the series numbers are figures which is convenient for identification and searching.
● 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 directly understand whether the resonance point is found .
