中文摘要:
      电力电缆作为传送电能的通道,是电力系统的重要组成部分,为电力系统的稳定性和可靠性提供保障。然而,电缆在运行过程中,由于受到光照、电场、磁场、热及水分等因素的影响而使其聚合物绝缘材料发生老化,导致材料绝缘性能显著降低,甚至造成整个电力系统的瘫痪和报废。因此,关注电缆绝缘材料的老化现象对保证电气系统安全运行具有重要的理论意义和实用价值。文中综述了电绝缘材料老化的研究现状,深入分析了其老化原因、机理和表现形式,并从机理层面概述了电绝缘材料老化的诊断分析和预防措施。
英文摘要:
      Electrical cable, as the channel to transmit electric energy, is an important component of the electric system, and it can make sure the stability and reliability of cable. However, the aging of cable insulation, which was induced by the influence of external stimulation, such as light, electric field, magnetic field, heat and humidity during the application of process, may ruin the circuit board and paralyze the entire electronic system. Therefore, it possesses theoretical significance and practical value to understand the phenomena of insulation electrical aging. This paper reviewed the research progress about the aging of cable insulation materials, discussed the aging mechanism, introduced the diagnostic techniques of cable aging, and finally provided the prospects of possible aging precautions.
