Abstract

The invention discloses a device and method for laser remote removal of foreign matter on a transmission line. The device comprises a laser, a numerical control base, a light beam collimator, a visible indicating light unit, a scanning galvanometer, a distance measuring instrument, an electronic telescoping sighting device, a controller and an emitting barrel. By the adoption of the device and method, only one operator is needed, large-sized equipment or other auxiliary equipment is not needed, the operator does not have to climb a tower or a rope ladder, environment conditions such as the terrain and the line height do not needed to be considered, the device simply needs to be adjusted so as to be aligned to a target and emit lasers, the foreign matter can be removed or shot down within tens of seconds, the operator do not make any contact with facilities and equipment of the transmission line in the whole process, hot-line work can be conducted, the foreign matter on the transmission line can be remotely, rapidly and safely removed in time, and the application prospect is good.

Description

technical field

[0001] The invention relates to a laser remote removal device and method for foreign matter on a power transmission line, belonging to the technical field of power transmission and transformation. Background technique

[0002] At present, the vast majority of power transmission and distribution lines are erected in the air by bare metal wires without insulation protection through towers. However, floating foreign objects such as kites, kite lines, plastic sheets, and advertising sheets are easy to blow down to the bare metal wires. In general, once such floating foreign objects are soaked by rain, snow, and dew, it is very easy to cause faults such as phase-to-phase short circuit and single-phase grounding of the metal wires, which will cause tripping or damage to the transmission and distribution lines, and even fall to the point where people and animals can touch them. Foreign matter in the position may cause human and animal casualties. Therefore, it is ve...
