Study on XLPE Cable Voltage Withstand Test and Its Circuit Model

摘要

Analyze the application of resonant voltage withstand test in the XLPE cable voltage withstand test, and the two methods of variable frequency resonant voltage withstand test were compared by an example. By comparison, the resonant voltage test method can effectively simulate the field voltage withstand test of XLPE cable is found. Through the research of the traditional frequency conversion resonance voltage withstand test circuit, a new voltage withstand test model of cable is proposed, and models of young and old are compared by means of the spot testing, the conclusion of the new circuit model can be more accurate to complete the calculation of AC voltage withstand test is validated.
