Abstract
The invention relates to a monitoring and maintenance system of a power transmission system, and specifically relates to a ground wire on-line monitor system. The system comprises transformer stations, power transmission lines among the transformer stations and a ground wire or earthing device used for power transmission line examination and repairing. The ground wire or earthing device is provided with a position switch, a hitching signal processing module and a signal output circuit, wherein the position switch can induct whether the ground wire or the earthing device is grounded. An induction signal of the position switch is outputted to the hitching signal processing module. A signal output terminal of the hitching signal processing module is in a cable junction with a grounded power transmission line through the signal output circuit. The transformer stations are provided with a monitor terminal and a signal receiving circuit. The signal receiving circuit connects with a cable of the power transmission line and can receive a signal outputted by the signal output circuit. The monitor terminal can receive and process a signal received by the signal receiving circuit. According to the invention, management of power transmission line examination and repairing process is facilitated, and security of electric power system operation is raised.
