摘要:

覆冰現(xiàn)象時(shí)刻威脅著電力系統(tǒng)的安全運(yùn)行，過去幾十年里，研究人員采用各種措施來預(yù)防電力設(shè)備表面覆冰，但這些措施都無法從根本上解決該問題。超疏水涂層由于具有獨(dú)特的微納米結(jié)構(gòu)及低表面能物質(zhì)，在低溫環(huán)境下，能夠延緩結(jié)冰且降低表面的冰附著力。從超疏水涂層的防覆冰機(jī)理入手，重點(diǎn)綜述國(guó)內(nèi)外超疏水涂層防覆冰的實(shí)驗(yàn)研究現(xiàn)狀，并將影響防覆冰性能的因素分為環(huán)境因素和基底因素，分析當(dāng)前方案的局限性，同時(shí)闡述提高超疏水涂層機(jī)械魯棒性的設(shè)計(jì)與制備方面的最新進(jìn)展，最后提出超疏水涂層在電力系統(tǒng)應(yīng)用中存在的問題以及未來的發(fā)展方向。該綜述有助于研究人員建立評(píng)估超疏水涂層的防覆冰性能的試驗(yàn)規(guī)范，并推進(jìn)超疏水涂層防覆冰技術(shù)在電力系統(tǒng)中的應(yīng)用。

Abstract:

Icing always threatens the safe operation of power system. In the past few decades, researchers have taken various measures to prevent the icing on the surface of power equipments, but these measures can not fundamentally solve this problem. Due to its unique micro-nano structure and low surface energy materials, superhydrophobic coating can delay icing and reduce the adhesion ability of surface ice at low temperature. Therefore, started with the anti-icing mechanism of superhydrophobic coating, this paper focuses on the experimental research status of anti-icing of superhydrophobic coating at home and abroad, divides the factors affecting the anti-icing performance into environmental factors and substrate factors, analyzes the limitations of the current schemes, and expounds the latest design and preparation progress on improving the mechanical robustness of superhydrophobic coating. Finally, the problems existing in the application of superhydrophobic coating in power system and the future development direction are put forward. This review is helpful for researchers to establish test specifications for evaluating the anti�瞚cing performance of superhydrophobic coatings and promote their application in power system.
