Description

Technical Field

[0001] The invention relates to the technical field of overhead line transmission lines, and in particular to an anti-icing conductor, a production line and a production method thereof. Background Art

[0002] With the changes in weather in recent years, especially extreme ice and snow weather, the safe operation of the power grid has been greatly damaged. The power grid line equipment is seriously covered with ice, which brings great challenges to the safe and stable operation of the power grid and the reliable power supply of customers. When the low-temperature rain falls on the transmission line below zero degrees, it will freeze and cover the transmission line with ice. The icing of the transmission line is one of the most serious disasters in the power system. The icing causes ice flash of insulators, overload, line dancing, and even line breaking and tower collapse accidents, which seriously threaten the safe operation of the power grid. Among them, the frost icing is hard in texture, not easy to fall off, and has sufficient strength. It can cause the conductor icing to grow rapidly, and it is the main form of icing on the transmission line.

[0003] Existing anti-icing / deicing methods for transmission lines include thermal anti-icing / deicing, mechanical deicing, natural passive anti-icing / deicing and other deicing methods. However, the thermal anti-icing / deicing method has high energy consumption, the mechanical deicing method has low safety and work efficiency, the natural passive deicing method is too dependent on weather conditions, and the deicing effect is accidental. Other anti-icing / deicing methods remain in the theoretical verification and simulation stage. Therefore, these methods cannot fundamentally suppress and eliminate the occurrence of icing disasters on transmission lines.

[0004] At present, the anti-icing coating technology that has attracted much attention is a promising method for anti-icing of transmission lines. Anti-icing coating is used to construct a coating on the surface of the transmission line, which actively inhibits and alleviates the formation and growth of ice on the transmission line during the icing period, and can fundamentally eliminate the occurrence of icing disasters on the transmission line. The anti-icing coating method has attracted extensive attention from the engineering and academic circles because of its low energy consumption and easy implementation. Anti-icing coating can be divided into three types: electrothermal coating, photothermal coating and ice-melting coating. Electrothermal coating is mainly used for anti-icing of insulators. By adding conductive fillers to the coating, it is applied on the insulator to form an electrothermal coating. Conductive fillers can reduce the resistivity of the coating. Under normal voltage operation, when the insulator is iced, the leakage current flowing through the coating increases, exerting an electrothermal effect, generating Joule heat to heat the coating surface, and playing a role in delaying or preventing icing. However, the anti-icing function of the coating is affected by the length of the insulator string and the diameter of the insulator, and it is not suitable for use in rime or wet snow weather. Photothermal coating refers to adding substances with good light absorption properties to the coating, which is applied to the transmission line to form a photothermal coating, improve the light absorption rate, and use the energy of sunlight to prevent icing or de-icing. Since photothermal coatings themselves have strict requirements on weather, the weather when icing disasters occur is not conducive to the function of photothermal coatings. Ice-melting coatings can reduce the ice melting temperature and achieve ice melting or de-icing by releasing small organic molecules. However, as time goes by, the release of freezing point inhibitors continues to decrease, so the ice-melting coating is a sacrificial coating and does not have long-term effectiveness. Therefore, there is an urgent need for an anti-icing conductor, a production line and a production method thereof to solve the shortcomings of the existing anti-icing coating method. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention designs a production line for anti-icing wires, including: a first cleaning device; a wire sandblasting machine, arranged at the output end of the first cleaning device; a second cleaning device, arranged at the output end of the wire sandblasting machine; a wire coiling device, arranged at the output end of the second cleaning device; a first spraying chamber, arranged at the output end of the wire coiling device; a first drying chamber, arranged at the output end of the first spraying chamber; a second spraying chamber, arranged at the output end of the second spraying chamber; and a second drying chamber, arranged at the output end of the second drying chamber.
