摘要
电缆在出厂和运行前都必须进行各种电气性能的测试,无论是何种形式的电气性能测试,电缆终端头都是电场最为集中的地方。应用有限元软件ANSYS分析电缆水终端周围的电场分布,可以清楚地观察到终端周围电场分布与水的电阻率之间的相互关系。此外,降低水的电阻率对于终端周围的电场分布起到很明显的均匀作用。对水终端进行电缆的耐压试验提供指导性的理论依据。
Cables should be subjected to and pass various electrical performance tests in the factory.Whatever tests they may experience ,cable terminals are the places where the electric stress is the highest.The relationship could be observed between the distribution of electric field and the resistance of water by using the software ANSYS to analyze the distribution of electric field around water sealing end.Reducing the resistance of water can make the distribution of electric field around water sealing end distributed more evenly.A theoretical basis is provided for the pressure test of cable using water sealing end.
