Fire attack device for clearing power transmission wire plastic foreign matters

Abstract

The invention relates to a fire attack device for clearing power transmission wire plastic foreign matters. The fire attack device includes a vertical rod, a transverse rod and an oblique rod which are arranged in a manner that the vertical rod, the transverse rod and the oblique rod form a right-angled triangle and are fixedly connected with one another end to end; one end of the transverse rod, which is connected with the oblique rod, is provided with an alcohol lamp; the alcohol lamp is arranged in a lamp protective barrel; the lamp protective barrel is arranged at an end portion of the transverse rod through a support which is used for positioning the lamp protective barrel and preventing the lamp protective barrel from swinging; a distance from the top end of the outer flame of the alcohol lamp which is lit to the upper edge of the lamp protective barrel is 4 + / -1cm; a perpendicular distance between the top end of the vertical rod and the upper edge of the lamp protective barrel is 2+ / -1 cm; and a portion of the transverse rod, which is adjacent to the vertical rod, is provided with a control ring which faces outwards and is used for hanging an insulating rope. The fire attack device for clearing power transmission wire plastic foreign matters of the invention has the advantages of simple structure, low cost, operation without power outage required, convenience, practicability and guarantee of reliable operation of a power transmission line.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to special equipment used in the maintenance process of power transmission lines. Background technique [0002] With the rapid development of the power system, the safe operation of transmission lines is directly related to power transmission, agricultural production and people's normal production and living electricity. The overhead lines of high-voltage transmission lines run outdoors for a long time. When encountering strong winds, floating objects will be scraped onto the wires, causing strip-shaped foreign objects to be wrapped around the transmission wires. Then cause mutual short circuit between the transmission lines, and seriously threaten the safety of the entire transmission line. [0003] Most of the foreign objects wrapped around the transmission wires are long strips, such as kites, kite strings, plastic films, etc. These common foreign objects are mostly fiber...

AI Technical Summary

Problems solved by technology

When encountering foreign objects entangled between the stalls, if the foreign objects are located between the horizontally arranged transmission wires, the operator can climb to the transmission wires and use the equipotential operation method to remove them; and if the foreign objects are located between the transmission wires arranged up and down, However, because the safety distance is not enough, the method of waiting for electricity can not be used, and only the power outage operation method can be used, which not only affects the normal operation of the electricity company, but also causes major economic losses to the power company.

In addition, in the process of removing foreign matter by using the equipotential operation method, a lot of manpower and material resources are required, and it is easily affected by the working environment such as weather and humidity, and the foreign matter between the transmission wire stalls cannot be effectively removed in time
