高压电缆缓冲层烧蚀故障与对策分析

Analysis of Ablation Failure and Alignment Strategy of High-voltage Cable Buffer Layer

阐述高压电缆的缓冲层结构发生烧灼故障,不能发挥良好的缓冲和保护作用,分析故障产生的原因。试验结果显示,进水受潮是缓冲层产生白色粉末及烧灼现象的主要因素,应采取多种措施,有效避免缓冲层出现此类问题,从而提高高压电缆的安全性。

This paper expounds that the buffer layer structure of high-voltage cables has a burning fault,which cannot play a good buffer and protection role,and analyzes the causes of the fault.The test results show that water ingress and moisture are the main factors causing white powder and burning in the buffer layer.Various measures should be taken to effectively avoid such problems in the buffer layer,thereby improving the safety of high-voltage cables.
