Study on Melting Ice Current Characteristics under Low Temperature and High Wind Speed

Abstract

Icing on transmission line becomes more serious in the past ten years, and the icing area gradually expanded from the traditional south to northeast area. Ice melting is an effective method to deal with the icing disaster. But the existing ice-melting research mainly focuses on traditional ice-coated areas with low wind speed and mild temperature. But it is difficult to apply to northern regions and alpine mountainous areas with low temperature and high wind speed conditions. In response to such issue, this paper establishes an equivalent thermal circuit model for ice melting process, and studies the quantitative effects of wind speed and temperature on the characteristics of ice melting current, and obtains the law of melting ice current under low temperature and high wind speed.it provides information for the parameter design of ice melting system in extremely cold regions.
