Description

Technical Field

[0001] The utility model relates to the technical field of deicing equipment, in particular to a deicing device for a power transmission line. Background Art

[0002] Transmission line de-icing devices are usually designed to cope with cold climate conditions. Transmission lines will be covered with ice when encountering heavy rain and snow in winter, which will increase the weight of the lines. Transmission line de-icing devices are used to prevent transmission lines and equipment from being damaged or affecting normal operation when covered with ice and snow.

[0003] At present, when ice is applied to existing transmission lines again, fixed or mobile ice melting devices are generally used to remove ice on transmission lines of 110kV and above, while there is no ice melting technology for transmission and distribution lines of 35kV and below. The principle of existing deicing equipment is that after ice is applied to the transmission line, a direct current is added to one end of the transmission line to melt the ice using the thermal effect of resistance. However, the deicing process is slow when this method is used, and the use of this direct current ice melting device requires the transmission line to be shut down, which affects the reliability of power supply.
