Problems solved by technology
Due to the high density of icing on the rime and its strong adhesion, it is not easy to fall off. When the amount of ice on the conductors and towers reaches a certain level, it will exceed the maximum mechanical load of the line design, which will easily cause broken lines and towers, insulators, etc. Accidents such as drop

Abstract
The invention discloses an anti-icing insulator device and a power transmission line having the same. The insulator device comprises an insulator chain formed by a plurality of insulators. The multiple insulators are divided into high-voltage-terminal insulators and rest of insulators according the voltage level of the insulator device; all surfaces of the high-voltage-terminal insulators are coated with semiconductor anti-icing coating materials; and only lower surfaces of the rest of insulators are coated with semiconductor anti-icing coating materials. According to the invention, the full-chain heat effect distribution way of the icing period is changed by changing resistance configuration of the high-voltage terminals and other zones of the insulator chain, so that the insulator chain has the better anti-icing effect and thus the damages on the insulators of the power transmission line by icing can be reduced.
Description
technical field [0001] The invention relates to an anti-icing insulator device and a power transmission line provided with the anti-icing insulator device. Background technique [0002] my country has a vast territory, and transmission lines need to face various extreme climatic conditions, especially in some mountainous areas. Due to the complex microclimate, icing problems will occur, which poses a serious threat to the safe operation of the power system. Studies have shown that icing poses a greater threat to transmission lines under wet growth conditions, that is, rime icing. [0003] Icing has two main effects on transmission lines, one is the impact on the mechanical properties of lines and towers, and the other is the impact on the electrical performance of lines. Due to the high density of icing on the rime and its strong adhesion, it is not easy to fall off. When the amount of ice on the conductors and towers reaches a certain level, it will exceed the maximum mech...
