110kV电压等级交联聚乙烯绝缘材料的老化特性

Aging Characteristics of 110 kV Voltage Level Cross-linked Polyethylene Insulation Material

随着电力事业的不断进步和发展,绝缘材料被广泛应用在电力电缆行业中,但是,由于绝缘材料内部以及外部缺陷问题,会造成材料提前失效的问题,基于此,要着重研究老化特性,从而更好地避免内外因素综合作用造成电缆系统应用失效。从电老化、热老化两个方面分析了110 kV电压等级交联聚乙烯绝缘材料老化的机理和具体特性行为。

With the continuous progress and development of the power industry,insulating materials are widely used in the power cable industry.However,due to internal and external defects of the insulating material,the problem of premature failure of the material will be caused.Based on this,we must focus on the aging characteristics,So as to better avoid the failure of cable system application caused by the combined effect of internal and external factors.This paper analyzes the aging mechanism and specific characteristics of 110 kV voltage level cross-linked polyethylene insulation material from two aspects:electrical aging and thermal aging.
