Abstract

The invention discloses AC power transmission DC ice melting equipment based on self-ice-melting conductors. The equipment is characterized in that the equipment comprises a sending-end A-phase powertransmission line, a sending-end B-phase power transmission line, a sending-end C-phase power transmission line, an A-phase power transformation module, a B-phase power transformation module, a C-phase power transformation module, a level conversion module, an A-phase heat conductor, a B-phase heat conductor and a C-phase heat conductor. The self-ice-melting conductors are controlled by the powertransformation modules and the level conversion module, and ice melting can be conducted when high-voltage power transmission lines work, thereby avoiding the case that an existing ice melting technique needs to cut off power, and helping reliable operation of the high-voltage power transmission lines; and the high-voltage power transmission lines have no ice thereon, thereby preventing the phenomenon of dancing of the high-voltage power transmission lines and avoiding serious accidents of line breaking of the high-voltage power transmission lines due to icing.

Description

technical field [0001] The invention relates to the technical field of electric wire melting ice, in particular to an AC transmission DC ice melting device based on a self-melting ice conductor. Background technique [0002] In recent years, damage to power transmission equipment caused by freezing rain and icing has occurred frequently, and the resulting economic loss has become a problem that cannot be ignored. Severe line icing caused damage to multiple lines and towers, seriously affecting the safe and stable operation of the power grid. Moreover, the maintenance cost of tower damage is high, consuming a lot of manpower and material resources, and the corresponding maintenance work in rainy and snowy weather will bring great challenges to maintenance personnel, and there is a huge potential safety hazard. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides an AC transmission DC ice-melting dev...
