摘要
分析了一起沿海地区户内柔性直流设备外绝缘积污爬电事件,对户内直流设备外绝缘积污进行了深入探讨。户内直流设备由于直流吸附作用且缺乏自清洁条件,积污特性受到户内杂质、湿度、温度等多种因素的显著影响,需引起重视。对于存在爬电情况的户内直流设备,可以结合实际情况,采取喷涂PRTV、加装增爬群、加装绝缘子、改善通风系统、定期清扫等措施。
There is little related researches on contamination of indoor DC equipment all the time. Through the introduction and analysis on the creepage event of external insulation of the VSC-HVDC equipment which is on the coast, this paper discusses the contamination accumulation of external insula- tion of indoor DC equipment. Due to the adsorption effect of DC and the lack of self-cleaning condition, contamination accumulation characteristics are greatly affected by many factors, such as impurity, temperature and humidity, which should given more attention. For indoor DC equipment which is creepage discharged, measures such as spray PRTV, install booster shed, add insulator, improving ventilate system, cleaning regularly can be taken by combining with the practical situation.
