带电清扫机器人绝缘安全分析

The Insulating Safety Analysis of Hot-Line Sweeping Robot

针对高电压环境下,当电介质中掺杂有金属导体时,提出一种带电作业机器人绝缘安全距离的分析方法.对于金属导体引起的电场不规则畸变,采用有限元的方法计算场强以验证是否超出临界值.该方法应用于带电清扫绝缘子机器人的绝缘安全分析中,并通过了试验验证.

This paper presented a method of calculating the insulating safety distances for hot-line working devices at high voltage when dielectric is adulterated with conducts. And finite element method was adopted to calculate the electric field strength to find whether it is beyond the critical. The above methods were applied to analyze the insulating safety of the robot for hot-line sweeping post insulators in 220 kV substation. These methods were testified by experimentations.
