怎樣避免電力電纜的渦流故障

   電力電纜施工采用鋼支架,也有用鋼質保護管、電纜卡與架空敷設等情況,但是只要會在電力電纜四周形成閉合回路均會造成渦流,電力電纜系統中電流越大渦流也越大。某單位具體施工中遇到過此現象,有客戶購買了400m的架空電流,用鋼絞線支撐,電纜卡子固定,在正式投運后不久便發生了接地故障。經過檢修發現,是電纜卡子和鋼絞線形成了閉合回路,產生的渦流將電力電纜絕緣層燒壞。針對此問題,建議可以在電纜卡子與鋼絞線結合處用絕緣層隔離后,不形成閉合回路也就避免了渦流產生。經過客戶實踐驗證,這樣運行多年均為發生接地故障。由此可見,在電力電纜施工時,必須采取措施,使電纜周圍不能形成鋼(鐵)性閉合回路,防止電纜引起渦流現象發生。
