애자 청소 작업은 애자의 절연 저하를 사전에 예방하기 위해 고소 고압의 환경에서 이루어지는 위험한 작업으로 정비작업의 능률과 정밀도가 떨어져 로봇을 이용한 활선 애자 청소 및 진단의 자동화가 요구되어진다. 이러한 요구에 따라 활선 애자 청소 로봇이 개발되고 있다. 본 논문에서는 개발된 애자 청소 로봇 제어를 위해 마스터 슬레이브 구조를 갖는 제어 시스템 구성을 제안하고, 실험을 통해 구현한 제어 시스템의 효용성을 보인다.

To prevent an insulator failure, an automatic cleaning and inspection robot was developed for suspension insulator strings. The robot autonomously moves along the insulator string using the clamps installed on its two moving frames. Especially, unlike the existing cleaning robots using jets of water, the robot system adopts a dry cleaning method using rotating brushes and a circular motion guide. In addition, a mechanized brush bristles and a voltage-balancing contactor are devised to increase cleaning efficiency and to prevent arc generation under live-line conditions, respectively. We confirmed its effectiveness through experiments.

The distribution live-line work method is an operation method of working in a state in which electricity flows through overhead distribution lines to minimize inconvenience to electric customers due to power failure. In June 2016, to strengthen the safety of electrical workers, Korea Electric Power Corporation announced that it would in principle abolish the rubber glove method, in which workers wore protective equipment such as rubber gloves and performed their maintenance work. In addition, KEPCO announced that it would develop a short-range live working method using smart sticks and an advanced live-line maintenance robot system where workers work without touching wires directly. This paper is a preliminary study for the development of the live-line maintenance robot system, and deals with the results of analyzing the technical feasibility of whether the live works performed by workers can be replaced by robots or not.
