Description

Technical Field

[0001] The utility model relates to the field of anti-icing and de-icing of overhead cables, and in particular to a resistance wire winding device;

[0002] The utility model also relates to an intelligent wiring device;

[0003] The utility model also relates to a cable external heating ice-melting device. Background Art

[0004] The thermal deicing methods used in the prior art include overload current, load, high-frequency excitation, composite conductor, AC short-circuit current and other ice-melting methods. Among them, the overload current and load deicing methods use the increased current of the transmission cable or the increased resistance of the transmission cable to generate heat to achieve the purpose of ice melting. The disadvantages are: high energy consumption, and the need to replace the existing transmission cable, which is costly; the high-frequency excitation deicing method is currently immature and difficult to implement; the composite conductor deicing method requires the overhead power line conductor to be made into a composite conductor with a changeable current-carrying cross-section, and an automatically controlled composite switch device is installed on it. When the ice thickness on the conductor reaches the set value, the composite switch automatically disconnects the inner conductor loop of the composite conductor, so that it exits the current-carrying operation, and only retains the outer conductor to carry current, increasing the resistance (current density) of the current-carrying conductor, thereby increasing the heat generated by the conductor to achieve the purpose of ice melting. After the ice melting is completed, the composite switch automatically connects the inner conductor loop to restore the full-section current-carrying operation. For multiple split conductors, the line current can also be concentrated on a certain split conductor to increase the heat and melt the ice. By switching between the split conductors, the ice on the line can be completely melted. Its disadvantages: it requires large-scale transformation of the line, which is expensive and difficult to apply on a large scale; the AC short-circuit current ice melting method uses short-circuit heating of the transmission cable to achieve the purpose of deicing. The disadvantages: it requires power outages, which will cause huge economic losses and serious social impacts, and has high energy consumption. Utility Model Content
