摘要/Abstract

摘要： 开发了一套干冰清洗车载系统,包括小型干冰清洗机、清洗头、绝缘臂、液压升降平台、履带式底盘、压缩空气系统及手动/遥控操作系统等部分。该系统利用干冰作为清洗介质,进行带电清洗变电站绝缘套管和支柱绝缘子,清洗过程中不会出现污闪事故,清洗效果好,作业速度快。电力检测中心所做的工频耐压试验和泄漏电流及电磁兼容试验表明,清洗车的绝缘性能满足220 kV变电站带电清洗作业清洗要求,且其无线通信在变电站环境中工作可靠,亦不干扰变电站内设备。干冰清洗车载系统是一种安全、高效的绝缘子表面清洗机械。

Abstract: A set of vehicle-based dry ice cleaning system was designed, which includes a dry ice cleaning machine, cleaning terminals, mechanical arms, a hydrautic driven lifting platform, caterpillar chassis, and compressed air system, etc. This system cleans the insulating bushings and post insulators in substations with living environment by using dry ice as the insulating medium. The system can not only work fast and clean effectively, but also prevent insulators from flashover. The results of power-frequency voltage-withstand tests and leakage current tests indicate that the insulativity of the material used by the vehicle system meets the requirements of live-line cleaning works in 220 kV substations. In addition, its wireless communication will not be affected by and will not interfere with the equipment in substations. Therefore, the vehicle-based dry ice cleaning system mentioned above is safe and efficient for insulator surface cleaning.

Key words: live-line working, transformer substation, insulator, dry ice, vehicle system
