摘要
随着工业化水平的不断提高,环境问题越来越严重,雾霾、酸雨、扬尘等恶劣天气越来越频繁,绝缘子污染程度日益严重,给电力设备的可靠运行造成巨大安全隐患。各种粉尘在风力、重力、电场力的作用下绝缘子设备的污秽快速增长,当天气潮湿时,灰尘中的可溶性物质溶于水中,形成导电水膜,泄漏电流沿绝缘子的表面流过造成闪络事故。针对现状,研制直流换流站绝缘子除污机器人,该机器人能够自动适应攀爬各种直径的绝缘子,自动识别和跨越法兰,可在绝缘子上完成行走、吹灰、清污、喷水、吹干等一系列工作,安全、高效、便捷、智能地完成绝缘子清扫除污工作,为直流输电系统的稳定运行提供有力保障,具有很高的行业推广价值,为绝缘子设备检修工作标准化提供新途径。
With the continuous improvement of the level of industrialization,environmental issues and inclement weather,such as haze,acid rain and dust,have become more serious frequently. The degree of insulator pollution is becoming more and more serious,which results in a huge security risk to the reliable operation of power equipment. Under the action of wind force,gravity and electric field force,the pollution of insulator is increasing rapidly.When the weather is wet,the soluble substance in dust is dissolved in water,forming a conductive film,and the leakage current will flow along the insulator surface,resulting in flashover accident. Aimed at the present situation,a DC converter station insulator decontamination cleaning robot is developed which can automatically adapt to climb various diameters insulators,identify and across the flange,and can walk on the insulator,blow soot,purge,spray,blow dry and more. The insulator cleaning decontamination work can be completed safely,efficiently,conveniently and intelligently by the robot,which provides a strong guarantee for the stable operation of the HVDC system and a new way for the standardization of the insulator equipment overhaul work. So the robot should have a high overall industry application value.
