Design of Automatic Disconnection Device for Non-power Outage Operation of High-voltage Line

Abstract A set of remote electric control disconnection device for high-voltage line with strong adaptability, easy operation, and high safety has been designed to address the problems multiple spans, wide coverage, difficulty in coordinating power failure construction crossing operation. The design process aimed reduce weight improve reliability mechanical structure, conducted computation simulation traction force load electrified tight cable. Based on live device, experiments were different spans cable diameters, while meeting scope infrastructure sections. proved that good effects practical applications, can select any point straight span break cable, order achieve safe convenient uninterrupted operations recovery service.
