Problems solved by technology

[0003] At present, when dealing with live objects on transmission lines, the cutting method of live double-head tackle is often used for processing. When the existing double-head tackle is working, ground workers need to pull the insulating rope tied to the double-head tackle, and pull the insulation rope back and forth. The rope makes the foreign matter rub between the double-head block and the transmission line, and then cuts it off. However, when the foreign matter i

Abstract

The present invention discloses a power transmission line foreign matter barrier eliminating pulley which belongs to the power grid field, and is used for solving the technical problem in the prior art that the pulley eliminates the foreign matters in a friction cutting manner, so that the efficiency is low, and the working strength is large. The power transmission line foreign matter barrier eliminating pulley of the present invention comprises a pulley body, and a traveling pulley for sliding on a power transmission line, a rotating rack, and a driver for driving the rotating rack to rotate are arranged on the pulley body. The rotating rack is equipped with a thermal cutting member used for fusing the foreign matters, and the pulley body is equipped with a power supply for supplying power to the thermal cutting member. The power transmission line foreign matter barrier eliminating pulley of the present invention is applied to the high voltage power transmission lines of a power grid.

Description

【Technical field】 [0001] The invention relates to a pulley for removing obstacles of foreign matter in a power transmission line. 【Background technique】 [0002] With the development of the economy, there are more and more greenhouse planting operations and outdoor construction operations, and more and more objects such as kites, balloons, plastic films, and sunshade nets for vegetable greenhouses are blown up by strong winds and hung on high-voltage lines. In rainy or foggy days, phase-to-phase short circuit is likely to occur and cause the power grid to trip. Therefore, once it is found, it is necessary to organize live maintenance personnel to remove live foreign objects in time. [0003] At present, when dealing with live objects on transmission lines, the cutting method of live double-head tackle is often used for processing. When the existing double-head tackle is working, ground workers need to pull the insulating rope tied to the double-head tackle, and pull the insu...
