Abstract

The invention provides a modifying method of super-hydrophobic performance of indoor power transformation equipment. The modifying method includes following steps: 1), pretreating: roughening the surface of the indoor power transformation equipment; 2), coating: adopting a spin-coating or dip-coating mode to coat super-hydrophobic nano paint on the surface, of the indoor power transformation equipment, pretreated in the step 1), and drying at 50-80 DEG C to complete modification of the super-hydrophobic performance of the indoor power transformation equipment. After being modified through the modifying method, a super-hydrophobic protection film is formed on the surface of the indoor power transformation equipment, and a contact angle of water on the surface of the indoor power transformation equipment is 161-175 degrees; a rolling angle is less than 8 degrees, so that ultrahigh hydrophobicity of the surface of the indoor power transformation equipment is guaranteed, and the indoor power transformation equipment has excellent high-temperature resistance, oil resistance and self-cleaning performance.

Description

technical field [0001] The invention relates to a method for transforming the superhydrophobic performance of electric equipment, in particular to a method for transforming the superhydrophobic performance of indoor power transformation equipment. Background technique [0002] With the continuous rapid growth of my country's economy, the State Grid Corporation of my country, based on the basic national conditions of China's unbalanced energy distribution and productivity development, plans to build AC 1000 kV and DC ±800 kV UHV power grids in order to optimize the allocation of power resources in a wider range , to realize the efficient utilization of my country's limited energy resources. The pressure on indoor substations is increasing, and the internal machine structure is becoming more and more complex, including switch cabinets, voltage transformers, current transformers, lightning arresters, bushings, insulators, lightning arresters, station transformers, grounding tran...
