AC Resonant Test Set , High Voltage Cable Testing Equipment , AC Withstand Voltage Test Set
I. Application :
AC resonant test set is a kind of high voltage cable testing equipments for applied withstand voltage , which can be classified as variable frequency and variable inductance resonant test system. The former is tuned to resonance by regulating test frequency and the latter is by adjustable inductance. Different regulation modes lead to the same objective, that is, large capacity output on test object can be obtained by inputting small capacity power supply.
For large capacity test objects like XLPE HV cable, the biggest difficulty for adopting power frequency or approach power frequency AC voltage withstand test as acceptance test for XLPE insulating cable, is that it needs power supply and equipments with large capacity. For instance, given a 630mm2, 110kV XLPE cable with capacitance of 0.188uF/kM, the test parameter of each cable is 2.9MVA/128kV/22.7A if cable length is 3kM. Then there has a conclusion that it is impossible to do field test in traditional way. However, in variable frequency resonant test system, by dropping test frequency on one hand, and with a high quality factor (Q) on the other, the required capacity of input power supply is 1/Q of that of test power, thus dramatic reductions in volume and weight of test equipments are available, ideal for field test.
Fanke company owns many years of manufacturing experience in this type of testing equipment, customized types of such equipment according to the test needs of different customers, including OEM services, The components of the sets can also be ordered separately.
II. Main Components of AC Resonant Test Set With Variable Frequency
1. Isolation transformer
2. Variable frequency power source
3. Excitation transformer
4. HV test reactor group(resonant inductor)
5. Voltage divider
6. Optional part
6.1 Load capacitor
6.2 HV damping blocking inductor
Note:
1).Load capacitor can be optional when small load line is tesing or need analog load to control test frequency.
2).Test reactor can be produced to be 130KV,150KV,155KV,200KV, 250KV, 300KV, 350KV, 400KV for each piece rated voltage according to different tested object scope or customer requried. The max. rated current of each HV reactor can be 1~5A,10A,15A,20A,25A,30A.
VF: Variable Frequency Power Supply Source which is control and measurement part in the test circuit.
T : Excitation Transformer which provide the exciting voltage for HV test reactor
L : Test Reactor which is resonant inductance in the LC circuit and produce the test voltage
Cx: Tested Equipment
MOA1: Lightning Arrestor is protection part on the excitation transformer
C1,C2: Voltage divider(C1 is high voltage arm,C2 is low voltage arm ) which is HV voltage measurement part
