  • 高压电缆是决定电力输送质量和容量的关键要素. 聚丙烯由于自身优良的耐热性、绝缘性和绿色环保性被广泛关注, 并应用于电缆绝缘材料开发. 高压电缆聚丙烯绝缘材料需要承受脉冲电压和直流额定电压, 容易引起电场畸变从而引发空间电荷积累. 此外, 电缆运行过程中, 温度会急剧升高, 严重影响电缆的绝缘性能, 导致电树枝的引发和生长. 因此需要对高压电缆进行电场调控从而抑制电场畸变、局部放电、电树枝化等劣化现象的出现. 本文重点介绍了高压直流电缆聚丙烯绝缘材料电场调控的理论与方法, 分析了当前电场调控的重点, 最后展望了聚丙烯电缆绝缘的应用前景.
    High voltage cable is the key factor to determine the quality and capacity of power transmission. Polypropylene has widely attracted more attention because of its excellent heat resistance, insulation and green environmental protection, and it is used as cable material. Polypropylene insulation material for high voltage cable needs to bear pulsed voltage and the DC rated voltage, which can easily cause electric field to be distorted and lead the space charge to be accumulated. Meanwhile, the change of cable temperature will also affect the conductivity of insulating material and promote the accumulation of space charge, resulting in the distortion of internal electric field of insulating material and the initiation and growth of electric tree. Therefore, it is necessary to regulate the electric field of high voltage cable so as to suppress the deterioration phenomena such as electric field distortion, partial discharge and electrical demoralization. In this work, the theory and method of regulating DC electric field of polypropylene insulation of high voltage cable is first introduced. Then the main direction of electric field regulation is presented. Finally, the application prospect of polypropylene cable insulation is also put forward.
