Research on breakdown characteristics of oil-paper insulation in compound field at different temperatures

摘要：

　　The breakdown characteristics of oil-paper insulation in AC,DC and compound field at different temperatures were studied.The breakdown mechanism of oil-paper insulation at different temperatures and in AC and DC electric fields was analyzed.The breakdown characteristic mechanisms of the oil-paper insulation in the compound field at different temperatures were obtained: the dielectric strength of oil-paper compound insulation is changed gradually from dependence on oil dielectric strength to dependence on paperboard dielectric strength at low temperature.The dielectric strength of oil-paper compound insulation is always related to the oil dielectric strength closely at high temperature with decrease of AC content.
