摘要:
为了研究冷缩式电缆中间接头的电场分布并对其结构参数进行优化,首先,建立电缆中间接头的有限元仿真模型;然后,利用该模型对中间接头的结构参数配合进行分析;最后,根据分析结果制作一个10 kV冷缩式电缆中间接头,并对该样本开展局部放电和耐压试验.仿真与试验结果表明:通过合理优化应力锥和屏蔽管的结构参数,当应力锥的轴向长度、端部曲率半径及厚度分别为65,25和2.5 mm,屏蔽管长度和端口形状的分别为170 mm和90°,应力锥与屏蔽管之间的距离为60 mm,中间接头本体长度为420 mm时,样品的最大场强和最大切向场强小于30 kV·cm-1(空气击穿场强)且其交界面上的电场分布较为均匀;其可通过局放与耐压试验,满足设计要求,为10 kV冷缩中间接头的合理设计提供理论依据.
Abstract:
In order to study the electric field distribution and optimize the structural parameters of the cold-shrinkable cable intermediate joint, the finite element simulation model of the cable intermediate joint is established firstly, and then the structural parameters matching of the intermediate joint is analyzed by using the model. Finally, a 10 kV cold-shrinkable cable intermediate joint is made according to the analysis results and the sample was made the discharge and voltage withstand test. The simulation and test results show that: By reasonable optimizing the structural parameters of stress cone and shielding tube, when the axial length, curvature radius and thickness of stress cone are 65, 25 and 2.5 mm respectively, the length and shape of shielding tube are 170 mm and 90° respectively, the distance between stress cone and shielding tube is 60 mm, and the length of intermediate joint body is 420 mm. The maximum field strength and tangential field strength of the sample are less than 30 kV·cm-1(air breakdown field strength)and the electric field distribution on theinterface is more uniform. The design requirements can be met by partial discharge and voltage withstand test, which provides a theoretical basis for the reasonable design of 10 kV cold shrinkage intermediate joint.
