Abstract

The invention discloses an overhead ground wire repair device, which comprises a structural frame, an electric motor and a clutch which are connected. The electric motor is arranged inside the structural frame. An output end of the electric motor is connected with the clutch. A signal receiver for receiving a control command is arranged at the top of the electric motor. The clutch is provided witha first port and a second port. A traveling device is arranged above the first port. The traveling device is connected with the first port. A pressing mechanism is arranged above the second port. A repair device is arranged above the pressing mechanism. The repair device is connected with the structural frame. The pressing mechanism is used for pressing the repair device. The repair device is used for repairing an overhead ground wire. Instead of the staff, the overhead ground wire repair device can repair the overhead ground wire which is broken by using a repairing pipe, the efficiency of the repair work of the overhead ground wire can be increased, the stability of the power supply of a transmission line is ensured, the occurrence of disconnection accidents is avoided, and the repair effect is good.

Description

technical field

[0001] The invention relates to a repair device, in particular to an overhead ground wire repair device. Background technique

[0002] In addition to bearing the thermal effect of short-circuit current, load current, and lightning current, the overhead ground wire will also be attacked and damaged by the external harsh environment during operation, resulting in damage to the ground wire and even broken strands. Broken strands will not only cause uneven stress distribution of the ground wire, excessive local stress, and increase the possibility of further disconnection, but also reduce the lightning protection effect of the ground wire, increase the risk of lightning strikes on the line, and eventually lead to the outage of the line. Especially for ultra-high voltage and ultra-high voltage lines, the ground wire also shoulders the mission of serving as a carrier communication channel and supplying power to low-power users. Therefore, it is extremely important ...
