浅析10 kV电缆故障及运行维护措施

Analysis of 10 kV Cable Faults and Operation and Maintenance Measures

10 kV电缆若发生故障,将会严重影响用户的用电体验。分析10 kV电缆故障原因,包括线路升温造成故障、过流保护不够灵敏、电缆外护套穿孔、电缆受到外力破坏、断路与接地故障等,并根据故障提出相应的解决措施,如加强用电负荷与温度监测、电缆绝缘检测与腐蚀监测、10 kV电缆敷设质量验收等。

If the 10kV cable fails in use,it will seriously affect the user's electricity experience.The causes of 10kV cable fault mainly include:line temperature rise,insufficient sensitivity of overcurrent protection,perforation of cable outer sheath,cable damage by external force,open circuit and grounding fault.Put forward corresponding solutions according to different faults,mainly including:strengthening power load and temperature monitoring,cable insulation detection and corrosion monitoring,10kV cable laying quality acceptance,etc.
