Abstract

The invention provides a power transmission line foreign matter cleaning device comprising a hand-held part, a foreign matter collecting part (20) which is connected on the hand-held part, and a cutting part which is fixedly arranged on the foreign matter collecting part (20) and used for cutting a foreign matter wound on the foreign matter collecting part (20). Height of the cutting part is less than that of the foreign matter collecting part (20). The foreign matter hung on a power transmission line is picked up by the foreign matter collecting part and wound on the foreign matter collecting part, then the foreign matter is cut after being contacted with the cutting part and then falls off from the power transmission line. According to the power transmission line foreign matter cleaning device, the foreign matter hung on the power transmission line can be high-efficiently cleaned, and operation safety of the power transmission line can also be ensured.

Description

technical field [0001] The invention relates to electric power maintenance facilities, in particular to a foreign matter removal device for power transmission lines. Background technique [0002] It often happens that light and slender objects such as plastic colored strips, aluminum foil, kite lines, tapes, etc. are hung and wound on the transmission line due to natural or human factors. If the foreign object hanging on the transmission line is a conductor, it may cause an electrical accident in which the transmission line is grounded or short-circuited, which not only affects the power supply, but also the huge short-circuit current and high voltage can pose a huge threat to people and electrical equipment. The harmfulness of foreign objects hanging on wires has even become one of the means of war. For example, in the Kosovo war against Yugoslavia in 1998, the United States dropped graphite bombs to destroy the power grid. The basic working principle of graphite bombs is t...
