Abstract

In recent years, with the vigorous construction of the ultra-high voltage grid, the line operating voltage level has become higher and higher. In order to ensure the safe operation of the transmission line, the line insulator string has a length of several tens of meters, and traditional manual testing has been unable to meet the requirements. With the continuous maturity of wireless communication technology, electromagnetic compatibility technology, sensor technology and other comprehensive technologies, it is necessary to develop an insulator string detection robot to replace artificial insulator detection work on UHV transmission lines. By means of wireless sensor communication technology, electromagnetic compatibility technology, video image technology and many other technologies, the insulator detection robot designed in this paper has realized automatic detection of zero resistance value of insulator of UHV transmission line. In addition, the real-time monitoring of insulator resistance value can be carried out through wireless communication to achieve the purpose of timely alarm. In addition, the robot's motion status and the insulator's field status can be observed in real time through video image acquisition. The insulator detection robot designed in this paper realizes the automatic detection of the zero value of insulator of the UHV DC transmission line. It can adapt to the UHV AC DC transmission line with different voltage levels by changing the length of the climbing arm, and at the same time adapt to the climbing detection of the string insulator of tension tower and the vertical insulator of the straight tower. The problem that the insulator string of the UHVDC transmission line can not be automatically detected by electric charge has been solved. It greatly improves the efficiency of insulator detection and the automation level of power transportation maintenance, reduces the cost of human transportation, and creates higher economic and social benefits.

特高压直流输电线路绝缘子检测机器人系统的设计与应用

近年来，随着特高压电网的大力建设，线路运行电压水平越来越高。为了保证输电线路的安全运行，线路绝缘子串的长度有几十米，传统的人工测试已经无法满足要求。随着无线通信技术、电磁兼容技术、传感器技术等综合技术的不断成熟，有必要研制绝缘子串检测机器人来代替人工在特高压输电线路上进行绝缘子检测工作。本文设计的绝缘子检测机器人，利用无线传感器通信技术、电磁兼容技术、视频图像技术等多种技术，实现了特高压输电线路绝缘子零电阻值的自动检测。此外，还可以通过无线通信对绝缘子电阻值进行实时监测，达到及时报警的目的。此外，通过视频图像采集，可以实时观察机器人的运动状态和绝缘子的场态。本文设计的绝缘子检测机器人实现了对特高压直流输电线路绝缘子零值的自动检测。通过改变爬升臂的长度，可以适应不同电压等级的特高压交直流输电线路，同时适应张力塔串绝缘子和直塔竖绝缘子的爬升检测。解决了特高压直流输电线路绝缘子串不能通过电荷自动检测的问题。大大提高了绝缘子检测效率和电力运输维护自动化水平，降低了人力运输成本，创造了更高的经济效益和社会效益。
