Oiled paper compound insulation electrical ageing test system

The invention discloses an oiled paper compound insulation electrical ageing test system which comprises an alternating current-direct current high voltage power supply, a high voltage capacitance-resistance divider, an oiled paper insulation sample tank, a partial discharge measuring instrument and an upper computer. The alternating current-direct current high voltage power supply is connected with the oiled paper insulation sample tank. The high voltage capacitance-resistance divider is connected with the oiled paper insulation sample tank. The partial discharge measuring instrument is connected with the oiled paper insulation sample tank, and collects partial discharge signals inside an oiled paper insulation sample. The upper computer is in two-way communication connection with the alternating current-direct current high voltage power supply and the partial discharge measuring instrument. According to the oiled paper compound insulation electrical ageing test system, alternating current-direct current compound voltage is adopted for oiled paper insulation, accurate and accelerated ageing is conducted on a solid insulation paper board, and an oiled paper insulation electrical ageing laboratory test is achieved.
