高压电器绝缘子污闪分析及防范措施

Pollution Flashover Analysis and Preventive Measures of High-voltage Electrical Insulators

分析了电力机车高压电器绝缘子污秽放电过程及机理,对影响绝缘子污闪的因素进行了总结;讨论了多种现有防污闪措施,并重点提出利用纳米二氧化钛自清洁技术实现瓷绝缘子防污闪的方案,论述其可行性,并展望了应用前景。

@@@@Discharge process and mechanism of the pollution high-voltage electrical insulators on the roof of the electric locomotives are analyzed;the factors affect the insulator pollution flashover are summarized in this paper .After the discuss of a variety of existing anti-fouling flash measures ,the paper highlights that the Nano-titanium dioxide self-cleaning technology is an effective solution to pre-vent the dirty porcelain insulator from discharging .
