APPARATUS FOR TESTING THE IMPULSE OVERLAP INSULATION OF HIGH VOLTAGE DC CABLES

摘要

The present invention relates to a shock wave superimposed insulation test apparatus for a high voltage DC cable, comprising: a DC generator for converting AC power to DC high voltage power and outputting it; A shock wave generator for generating and outputting a shock wave of a specified waveform; And an overlapping portion for performing a shock wave overlap insulation test by applying a DC voltage generated by the DC voltage generating unit and a shock wave generated by the shock wave generating unit to the DC cable sample.
