Effect of Crosslinked Byproducts on Dielectric Properties of Crosslinked Polyethylene Cable Insulation Materials
摘要
Abstract
The effects of three crosslinked byproducts of acetophenone,α-methylstyrene and isopropyl alcohol on space charge formation and conductivity in crosslinked polyethylene(LDPE)cable insulation materials were studied.The results show that isopropyl alcohol has the greatest effect on the conductivity of LDPE,followed by α-methylstyrene and acetophenone.This result may be due to the formation of different charges near the electrode caused by isopropyl alcohol,which enhanced the electric field near the metal-dielectric interface and led to the increase of current value.The content of crosslinked byproducts in cable is closely related to the electrical properties of cable.With the increase of by-product content,the conductivity of the cable increases and the insulation performance decreases.At the same time,it will increase the accumulation of space charge.The same charge was found in all samples,but the different charge was found only in the isopropyl alcohol-soaked LDPE samples.When the byproduct is present in the LDPE,a change in the conductivity value is observed,and the cross-linked byproduct improves the charge mobility in the LDPE.关键词
