摘要
电缆附件与电缆主绝缘间的握紧力是保证输电线路安全运行的关键,而实际测量附件绝缘与电缆界面的压力非常复杂,这对电缆附件的结构设计及判断老化情况带来诸多困难。针对电缆附件用硅橡胶绝缘,通过实际测量电缆绝缘XLPE及附件硅橡胶料的弹性模量,利用ANSYS软件建立10 kV电缆附件三维仿真模型,分析了电缆附件过盈量与面压之间的关系。
The grip strength between cable accessory and cable main insulation is the key factor to ensure the safety of electrical transmission line.But in fact,it is too complicated to measure the pressure at the interface between cable accessory and main insulation,as a result,it is very difficult to design the accessory structure and judge the aging state.Focused on the silicone rubber（SR） used in the cable accessory,the elasticity modulus of XLPE and SR sample was measured.Then the three dimensional simulation model for 10 kV Cable Accessory was built by ANSYS software.According to the model,the relationship between the shrink range and the interfacial pressure was analyzed.
