Abstract

The electrical property parameters are crucial elements in the design of cable accessories, emphasizing the significance of precisely understanding their operational characteristics. This study investigates the variations in the electrical properties of silicone rubber (SR) insulation under mechanical stretching. The distribution characteristics of relative permittivity and ac breakdown strength are determined based on the mechanical stretching state. Furthermore, the electric field strength and safety margin are calculated to assess the operational capability of cable accessories. Comparatively, the mechanical stretching effects lead to increased electric field strength and breakdown strength, ultimately enhancing the safety margins of cable accessories, with a noticeable impact as the stretching degree increases. These findings suggest that the cable accessories exhibit a higher safety level than initially anticipated and that mechanical stretching should be thoroughly considered in their design.

考虑机械拉伸的电缆附件精确操作特性

电性能参数是电缆附件设计中的关键因素，强调准确理解其工作特性的重要性。研究了机械拉伸作用下硅橡胶绝缘材料电性能的变化。根据机械拉伸状态确定了相对介电常数和交流击穿强度的分布特征。计算了电缆附件的电场强度和安全裕度，评估了电缆附件的运行能力。相比之下，机械拉伸效应导致电场强度和击穿强度的增加，最终提高了电缆附件的安全裕度，且随着拉伸程度的增加，影响显著。这些发现表明，电缆附件显示出比最初预期的更高的安全水平，在其设计中应充分考虑机械拉伸。
