摘要

电缆终端内高压电流环境造成的电场畸变会大大增加故障概率，降低操作安全性;因此，有必要保证端子内电场的均匀分布。简要介绍了高压电缆端子和非线性材料。制备了传统硅橡胶和添加纳米sio2的硅橡胶。测试了两种硅橡胶的电导率，并模拟了电缆端子的电场。结果表明，纳米sio2改性硅橡胶具有较高的非线性电导率，受温度的影响较小。仿真模型的计算结果也表明，采用改进硅橡胶作为增强绝缘体后，内部场强分布更加均匀，增强绝缘体上的最大场强更小。

Research on the electric field intensity distribution of high-voltage cable terminal improved by non-linear material

The electric field distortion caused by the high voltage current environment in the cable terminal will greatly increase the failure probability and reduce the operation safety; therefore, it is necessary to ensure the uniform distribution of the electric field in the terminal. This paper briefly introduced the high-voltage cable terminal and non-linear materials. The traditional silicone rubber and the silicone rubber added with nano-SiO2 were prepared. The electrical conductivity of the two silicone rubbers was tested, and the electric field of the cable terminal was simulated. The results demonstrated that the nano-SiO2 improved silicone rubber had a higher non-linear conductivity and was less affected by temperature. The calculation results of the simulation model also showed that the distribution of the internal field strength was more uniform, and the maximum field strength on the reinforced insulation was smaller after the improved silicone rubber was used as the reinforced insulation.
