Research on Key Technology of Arc Suppression Switch for Live Line Work in Distribution Network

With the rapid development of China's electric power industry, the technology of non-blackout operation in the distribution network is becoming more and more mature, and the reliability of power supply is also put forward higher requirements. Arc suppression switch is the main tool for the operation of no-load cable line with live connection, but there are few researches on it at home and abroad. In this paper, the principle of arc suppression switch is studied experimentally, and an insulated rod type electric arc suppression switch is designed, which changes the traditional operation mode of arc suppression switch, and provides a reference for the development of automatic operation field of arc suppression switch.
