Research on Embedded Partial Discharge Sensing Detection of Cable Joints Based on Capacitive Coupling

局部放电是电力设备中常见的故障形式,特别是在电缆接头中,由于制造工艺和材料缺陷等因素,局部放电现象可能会严重影响接头的可靠性和安全性。文章旨在探索一种基于电容耦合的电缆接头植入式局放传感检测技术,名为双极植入式局放传感单元,是通过在电缆接头内部植入微型传感器单元,实时感知局部放电信号,并提供接头故障检测和预警。

Partial discharge is a common form of fault in power equipment,especially in cable joints.Due to manufacturing processes and material defects,the phenomenon of partial discharge may seriously affect the reliability and safety of joints.This study aims to explore a capacitive coupling based embedded partial discharge sensing detection technology for cable joints.This technology embeds micro sensor units inside cable joints to sense partial discharge signals in real-time and provide joint fault detection and warning.
