Abstract

Çevresel ve
elektriksel zorlayıcı etkiler enerji iletim dağıtım hattında yaygın olarak
kullanılan silikon izolatörlerin yaşlanmasına sebep olurlar ve dielektrik performanslarını
azaltırlar. Mekanik olarak taşıma kolaylığı, esnekliği ve hafifliği ile öne
çıkan silikon izolatörler aynı zamanda yüksek elektrik direncine de sahiptir.
Bu yalıtkanların yapısındaki herhangi bir bozulma, elektrik kesintilerine neden
olarak ciddi finansal kayıplara yol açabilir. Enerji iletim-dağıtım hattı
boyunca izolatörlerde, tellerden geçen akımın ürettiği manyetik alanın etkisi
vardır. Bu alan, yalıtkan üzerindeki çalışma performansını değiştirecek bir
etkiye neden olabilir. Bu çalışmada, silikon izolatörlerin çalışma
performansını etkileyen AC manyetik alan, eğik düzlem testinde IEC 60587 ve
ASTM 2303 standartlarına göre incelenmiştir. Ek olarak, üretilen bir elektrik
alan ve kapasitif etki test edilmiştir. Numunelerin test süreleri, yalıtkan
yüzeyinde üst elektrottan toprak elektroduna akan kaçak akım ve yüzey koşulları
incelenmiş ve sonuçlar karşılaştırılmıştır.

POLYMERIC INSULATOR PERFORMANCE TEST UNDER MAGNETIC FIELD EFFECT

Abstract

The environmental and electrical stresses age silicone insulators
commonly used in energy transmission-distribution line and reduce their
performance. Silicon insulators, which stand out mechanically with their ease
of transportation, flexibility and light weight, have high electrical
resistance as well. Any deterioration in the structure of these insulators can
lead to power outages, causing serious financial loss. On the insulators along
the energy transmission-distribution line there is the effect of the magnetic
field generated by the current passing through the wires. This field can cause
such an effect that will change the working performance on the insulator. In
this study, AC magnetic field effecting the working performance of silicon
insulators was examined in inclined plane test according to IEC 60587 and ASTM
2303 standards. In addition, an electric field generated and the capacitive
effect were tested. Test times of samples, leakage current which flows on the
surface of insulator from top electrode to the earth electrode, and surface
conditions were examined and results were compared.
