Abstract

A pipe maintenance method and device is particularly suited for maintaining a pipe of a gas-insulated high-voltage line with a particle trap system extending along the pipe. The novel method enables poorly accessible sections to be reached. To this end, a maintenance unit is displaced along the particle trap system, and it is guided thereby.
