Problems solved by technology

[0002] At present, in the operation and management of the power grid, the staff often encounters the situation that the distance between the upper and lower cross-arms is small when the 110-220 kV multi-circuit live-line work is carried out on the same tower. In addition, after taking the limit measures, the effective working space still cannot meet the requirements of the operator's activity space, which brings great difficulties to the replacement of the linear insulators of the multi-circuit lines on the same tower, and often requires power outage measures for the lines, resulting in large Area grid power outages seriously affect the power supply reliability and power supply time of the grid

Abstract

The invention discloses an operation method utilizing remote control tightening device ground potential for replacing a multi-loop linear insulator string. By means of mutual cooperation of an electrician on the ground and an electrician on a tower, a series of operation is completed effectively, such as installation and fixation of a remote control tightening device and an adjustable wire backup protection rope, the take-out of a wire side socket locking pin, the lifting of a wire, separation of the insulator string from a wire side socket, the take-out of a cross arm side insulator locking pin, transfer between a new insulator string and an old insulator string, the installation of a locking pin on the cross arm side of the new insulator string, the installation of a wire side ball and the wire side socket, and the recovery of the locking pins. Therefore, the purpose of replacing multi-loop linear insulators in an electrified mode on a multi-loop tower with a small distance between cross arms is achieved effectively, the effect that operators are protected against the threat of high voltage is ensured effectively, and the operation method is safe and reliable; outages are reduced, a large-area power grid outage is avoided, and power-on time is ensured effectively.
