Description

technical field

[0001] The invention relates to a gear-driven high-voltage isolating switch transmission shaft rotation angle measuring device and method, and belongs to the technical field of high-voltage isolating switch state detection. Background technique

[0002] The transmission parts such as shaft pins and bearings of outdoor high-voltage disconnectors lack lubrication and relative movement. Mechanical failures such as jamming during opening and closing, inadequate opening and closing, and deformation of transmission connecting rods have become common problems. Through operation and maintenance work It is difficult for personnel to find early faults of opening and closing jams during daily inspections. Temporary maintenance after a fault will delay the power transmission time and affect the reliability of power supply. The state detection and analysis of the operating mechanism of the high-voltage isolating switch is to improve the reliability of power supply. import...
