Abstract

The invention relates to power system maintaining equipment, and particularly relates to a high-voltage cable deicing device. According to the high-voltage cable deicing device, a deicing vehicle is hung on a cable through two walking wheels; a framework of the deicing vehicle is internally provided with a weight box so as to guarantee that the gravity center of the deicing vehicle is located at the center of the framework; three deicing units in the deicing vehicle are distributed between a driving walking wheel and a driven walking wheel at equal intervals, and one pressing wheel unit is placed between two hoisting units; a control circuit in a remote controller can realize data interaction through a wireless signal receiving-transmitting circuit, a wireless signal receiving-transmitting circuit in an electric cabinet and a deicing vehicle control circuit; the deicing vehicle control circuit outputs a motor control signal to a motor driving circuit which is used for driving a motor to rotate; and the motor is used for driving the driving walking wheel to rotate. The high-voltage cable deicing device disclosed by the invention controls the deicing vehicle hung on the cable to be deiced in a remote control manner so as to realize remote control work. The high-voltage cable deicing device is applicable to deicing the high-voltage cable.

Description

technical field [0001] The invention relates to power system maintenance equipment, in particular to a high-voltage wire deicing device. Background technique [0002] In the northern part of our country, the temperature is low in winter, and ice, snow or freezing rain often occur. In recent years, with the change of global climate, rainy snow and winter rain have also appeared in the southern part of our country. Under this weather environment, It will cause the surface layer of the high-voltage cable used for power transmission to freeze. When the thickness of the ice on the surface of the cable exceeds the design standard, it will cause the cable to withstand excessive pressure, which will lead to serious accidents such as pulling down the high-voltage transmission pole, and then interrupt the power supply. . [0003] Most of the existing high-voltage transmission lines are laid in the wild with inaccessible and harsh geographical environment, which leads to the problem o...
