 ADSS kablosu: Güç iletişim sisteminde tamamen dielektrik kendinden destekli ADSS optik kablosunun uygulanması第1张

         ADSS Tüm Dielektrik Kendinden Destekli Optik Fiber Kablo ADSS kablosu kısaca 220kV, 110kV ve 35kV gerilim seviyesi iletim hatlarında yaygın olarak kullanılmaktadır ve genellikle mevcut hatlarda kullanılmaktadır. 


Tamamen dielektrik, optik kablonun tamamen dielektrik malzemelerden yapılmış olduğu anlamına gelir ve kendi kendini destekleyen, optik kablonun kendi takviye bileşenlerinin kendi ağırlığına ve dış yüklere dayanabileceği anlamına gelir. 


İsim, bu optik kablonun kullanım ortamına ve temel teknolojilerine işaret ediyor: kendi kendini destekleyen olduğu için mekanik gücü büyük önem taşıyor; tamamen dielektrik malzemeler kullanılır çünkü optik kablo yüksek voltajlı ve güçlü elektrik ortamındadır ve güçlü elektriğin etkisine dayanabilmelidir; bir elektrik direği kulesinde tepeden kullanıldığı için, optik kabloyu direk kulesine sabitlemek için eşleşen askılara sahip olmalıdır.

ADSS optik kabloları, yüksek voltajlı güç hatlarının yanına monte edildiğinden, yüzeyleri yalnızca geleneksel optik kablolar gibi UV 'ye dayanıklı olmakla kalmamalı, aynı zamanda yüksek voltajlı, yüksek voltajlı ortamların uzun vadeli taleplerine de dayanmalıdır. 


Optik kablo ile yüksek voltajlı faz hattı arasındaki ve ayrıca kablo ile toprak arasındaki kapasitif bağlantı, kablo yüzeyinde farklı uzaysal potansiyeller üretir. 


Yağmur, kar, don ve tozun varlığında bu potansiyel fark, sızıntı akımlarının nemli, kirli kablo yüzeyinden akmasına neden olur. 


Ortaya çıkan termal etki, kablo yüzeyinin belirli bölgelerinden nemin buharlaşmasına neden olur. Bu geçici buharlaşma, kaçak akımı kesintiye uğratarak yaylar ve önemli ısı üretir. Bu birikmiş ısı, kablo yüzeyini yakarak elektrik izleme olarak bilinen ağaç benzeri izler bırakır. 


Zamanla, dış kılıf bozulur ve aramid ipliğin mekanik özellikleri bozulur ve sonuçta kablo kırılmasına yol açar. 


Bu sorun iki ana bakış açısıyla ele alınmıştır. İlk olarak, aramid ipliğin dışındaki dış kılıfı çıkarmak için özel bir izleme önleyici kılıf malzemesi kullanılır, yani AT izleme önleyici kılıf, güçlü elektriğin neden olduğu optik kablo yüzeyinin elektrik izleme korozyonunu azaltmak için kullanılır;


 Ayrıca güç kulesi üzerindeki mekansal potansiyel dağılımı profesyonel yazılımlar aracılığıyla hesaplanmış ve elektrik alan gücü dağıtım haritası çizilmiştir. 


Bu bilimsel temele dayanarak, optik kablonun kuledeki belirli asma noktası, optik kablonun daha güçlü bir elektrik alanından etkilenmesini önlemek için belirlenir. 


ADSS optik kabloları, farklı güç yolları için farklı kılıflar kullanır. En yaygın iki ADSS kılıfı PE kılıf ve AT kılıftır. Sıradan bir polietilen kılıf olan PE kılıf, 350KV ve altındaki güç hatları için kullanılır. İzleme önleyici bir kılıf olan AT kılıf, 110KV ve üzeri güç hatları için kullanılır.
