Remote-control electric deicing machine for power overhead lines

Abstract

The invention discloses a remote-control electric deicing machine for power overhead lines. The remote-control electric deicing machine for the power overhead lines comprises a machine frame (1), wherein a driving gear (2), a driven gear (3) and a fixed support (4) are installed on the upper portion of the machine frame (1), a scraper knife (5) is installed on the fixed support (4), auxiliary wheels (9) are installed below the driving gear (2) and the driven gear (3), and a battery (17) and a control cabinet (18) are installed on the lower portion of the machine frame (1). The remote-control electric deicing machine for the power overhead lines is easy to operate, high in efficiency, good in deicing effect, capable of avoiding potential personal safety hazards of workers, wide in application range, capable of deicing the overhead ground lines and optical cable lines on which AC or DC deicing can not be conducted, low in required energy consumption, being controlled in a long distance, saving a large amount of labor, reducing a large amount of energy consumption, improving efficiency, saving capital and reducing cost.

Description

technical field [0001] The invention relates to an ice removal device for an electric overhead line, in particular to a remote control electric deicer for an electric overhead line. Background technique [0002] In the cold winter, power overhead lines are often covered with ice. The icing of transmission lines will affect the normal operation of the power system, and seriously directly lead to the disconnection of transmission lines and the collapse of towers, resulting in large-scale power outages and huge economic losses. Therefore, timely deicing must be carried out. At present, the deicing is mainly carried out manually by throwing ropes and rubbing or knocking with sticks, which is not only inefficient, but also has a large workload, poor deicing effect, and is dangerous. Especially in the mountainous areas of Guizhou, power lines are erected along the mountains, crossing canyons and deep ditches. Manual deicing is quite difficult, and the personal safety of workers c...

The icing of transmission lines will affect the normal operation of the power system, and seriously directly lead to the disconnection of transmission lines and the collapse of towers, resulting in large-scale power outages and huge economic losses. Therefore, timely deicing must be carried out

At present, the deicing is mainly carried out manually by throwing ropes for friction or knocking with sticks, which is not only inefficient, heavy workload, poor deicing effect, but also dangerous.

Especially in the mountainous areas of Guizhou, power lines are erected along the mountains, crossing canyons and deep ditches. Manual deicing is quite difficult, and the personal safety of workers cannot be guaranteed.

There are also AC and DC currents for ice melting, that is, using AC or DC current to heat the ice-coated wires for deicing, but this method has large energy loss, high equipment cost, and a small scope of application, so it cannot be used for overhead ground wires and optical cable lines. deicing
