Arc suppression methods and techniques are very important technical links in live working in distribution networks. At present, in addition to arc suppression equipment developed by various power supply companies themselves, there is a shortage of arc suppression equipment specifically designed for live working in the distribution network. The most common types are single-phase load switches and the "Bodhisattva" line jumpers from the US company Usro. The former is an arc suppression switch with a single closing or opening function, while the former is not visible for the closing and opening states of the moving and stationary contacts, while the latter is visible for the moving and stationary contacts. The single-phase fast opening and closing arc suppression switch introduced in this article for live working in 10kV distribution network is a newly developed arc suppression switch with visible dynamic and static contacts and integrated fast opening and closing functions
