铅封开裂产生悬浮电压对高压电缆附件影响消除

Eliminating the Impact of Suspension Voltage Generated by Lead Seal Cracking on HV Cable Accessories

高压电缆附件是电缆线路的重要组成部分,其运行质量直接影响电力系统的安全。高压电缆附件铅封开裂后金属护套接地不良导致悬浮电压产生。通过对悬浮电压产生原因及其对高压电缆附件影响的分析,在设计和运行两方面提出消除和预防悬浮电压产生的方案,从而消除悬浮电压的影响。

The HV cable accessories are an important part of cable lines,and their operation quality directly affect the safety of power system.After lead seal cracking on HV cable accessories,the poor grounding of metal sheath leads to the generation of suspension voltage.By analyzing the causes of suspension voltage and its impact on HV cable accessories,the schemes are proposed to eliminate and prevent the generation of suspension voltage in both design and operation,thereby eliminating the impact of suspension voltage.
