10 kV电力电缆中间接头施工工艺缺陷的研究

Research on the Installation Defects of 10 kV Cable Joint

模拟了10kV电缆中间接头在施工过程中产生的7种典型缺陷,采用有限元的方法进行仿真分析,在实验室环境下开展了现场试验,对仿真和试验结果进行记录和分析。研究表明:电缆接头在施工过程中产生的缺陷容易引起局部放电,导致电缆接头发生击穿事故。通过对仿真和试验结果进行分析,提出了有效的改进措施。

Seven typical defects of 10 kV cable intermediate joint during construction are simulated in the paper using finite element method.Lab tests are carried out and the data obtained during the test is analyzed comprehensively with simulation results.The results show that the defect of cable joint during construction is a potential lead to partial discharge,resulting in breakdown accident at cable joint.Effective improvement measures are proposed based on the key points identified.
