Description

Technical Field

[0001] The utility model belongs to the technical field of porcelain insulator surface coating detection, in particular to an icing performance detection device for porcelain insulators. Background Art

[0002] Ultra-high and ultra-high voltage (UHV) transmission is a crucial means of high-voltage, large-capacity, long-distance power transmission and grid interconnection in my country, and is of great significance to the development of my country's energy landscape. However, with the implementation of the "West-to-East Power Transmission, North-South Power Interconnection, and National Power Interconnection" strategy, and the construction of ultra-high and ultra-high voltage (UHV) transmission and transformation projects, an increasing number of ultra-high voltage (UHV) transmission lines and substations will pass through areas with complex environments such as icing, pollution, and high altitudes, making the problem of grid icing even more prominent. Extensive experimental research and theoretical analysis have been conducted domestically and internationally on the issue of "ice flashover" on outdoor insulators, and corresponding anti-icing measures have been implemented. Insulator anti-icing and de-icing methods can be broadly categorized into two main types: passive de-icing and active de-icing. Passive de-icing involves removing or clearing ice from porcelain insulators through the provision of human and material resources. Active de-icing involves treating anti-icing equipment or components before ice forms, leveraging the structural or chemical properties of the coating to delay ice formation or reduce ice adhesion after ice forms, thereby achieving de-icing.

[0003] At present, the use of coatings to prevent ice formation on ceramic insulators is still an emerging topic, and there is no detection of whether the coatings are effective in preventing ice formation under specific conditions. Utility Model Content
