Product Description

AC resonant test set for cable ,gis test 

I. AC Resonant Test System Product description
AC Resonant test system is mainly used for conducting the on-site AC dielectric test for electric equipment with large capacity, including medium-low voltage, high voltage and ultra-high voltage XLPE, GIS, motor stator, large-sized transformer and electric capacitor.
The series variable frequency resonant system is to change the system inductance and test frequency to make circuit in resonant condition. Its electric circuit is shown in Fig.2. The adoption of variable frequency resonant technology reduces the capacity of power source and the weight of equipment, which facilitates on-site test.
the AC Resonant test system is composed of  Variable-frequency power source, Exciting transformer, High voltage reactor,  Capacitive voltage divider composition.
and output voltage range of the AC Resonant test system is 0-1200kV, which can be customized according to your test requirements.

II. AC resonant test set Function:

1. Device with over-voltage,over-current, zero startup, system detuning,high voltage flashover fault,ect  protection function.the over-voltage over-current protection value can be set according to the needs of user.flashover protection movement when the test object flashover, and mark down flashover voltage value, for test analyzed.

2.The whole device ,the largest piece very light weight not more than 40kg and convenient for field use.

 

3.Device has four working mode, user-friendly according to the site condition flexible choice, improve test speed.working mode as automatic mode,manual mode,automatic tune mode and manual boost mode.

 

4.Can store and print data,nonlocal print data, the serial number of the stored data is number, easy to help users digital identification and searching.

 

5.Frequency starting point can be set arbitrarily within prescribed scope when the device automatic frequency sweep.Sweep frequency direction can choose to up or down,, meanwhile color LCD big screen display scanning resonance boost and timing curve, be convenient for the user intuitive understanding whether find resonant point.

6.Adopted DSP platform technology, according to user needs ,can conveniently increase or decrease function and upgrade, but also makes the man-computer exchange interface humanized.
