摘要
为研究碳纤维复合芯导线(ACCC)的起晕特性,基于小电晕笼电晕测量系统进行了ACCC-600/71单根导线和LGJ-630/45钢芯铝绞线单根导线起始电晕特性的对比试验。试验结果表明:在干净及人工涂污下,ACCC-600/71导线的起晕电压均要高出LGJ-630/45导线起晕电压,说明ACCC-600/71导线确实能够降低线路损耗,在节能、环保方面具有良好运行性能;表面污秽会降低导线表面粗糙度系数,从而大幅度降低起晕电压,且污秽物颗粒度越大影响程度越高。
In order to study the corona characteristics of aluminum conductor composite core (ACCC), corona onset tests of single ACCC- 600/71 conductor and I,GJ-630/45 conductor were performed based on the corona measurement system with small corona cage. The experimental result shows that: under clean and artificial smear conditions, the corona onset voltages of ACCC-600/71 conductors are higher than those of LGJ-630/45 conductor, which proves that ACCC-600/71 conductors can reduce the line losses and have good performance in energy saving and environmental protection. Surface contamination reduces the roughness factor of ACCC-600/71 and LGJ-630/45 conductors and greatly lowers the corona onset voltages. The bigger the particle size is, the higher the influence will be.
