Abstract
The invention relates to a cable line with a solar photovoltaic generating system for supplying power to an ice and snow melting device, belonging to the technical field of new energy application. A solar photovoltaic independent generating system is arranged at the top of each telegraph pole, the sun shines solar batteries to generate current, and the current is regulated by a conductor input controller and is input into an accumulator battery for storing electric energy for long. In low-temperature snow and ice day, the current is output from the accumulator battery, is regulated by the conductor input controller, is converted into AC (Alternating Current) through a conductor input inverter and then supplies power to an electrothermal heating cover net around the cable line, and the electric energy is converted into heat in the electrothermal heating cover net to effectively melt ice and snow fallen down the cable line such that the ice and snow cannot freeze and increase the weight of the cable line, thereby avoiding the situations that the electric energy cannot be supplied because the middle part of the cable line is broken, the telegraph pole is tilted and a supply network is broken; in addition, the anti-freeze safe power supply of the supply network is effectively protected by fully utilizing an unpolluted solar generating heating ice-snow melting device.
