冰緣現象 的英文怎麼說
中文拼音 [bīngyuánxiànxiàng]
冰緣現象
英文
periglacial phenomena-
Upon existent theoretical and experimental results and based on a great of laboratory investigations carried out in chongqing university, for the first time this paper studies systematically the insulators dc discharge performance and flashover mechanism of iced insulators in the complex atmospheric environment, which will contribute to the understanding of flashover phenomena observed on ice surface at low air pressure and provide the test and theoretical reference for hv and ehv transmission lines design and safety service
為此，在國內外現有工作的基礎上，通過大量的試驗研究，本文主要研究了復雜環境中絕緣子的直流閃絡特性及閃絡機理。其結果有助於進一步了解低氣壓下覆冰絕緣子的閃絡現象，並可為輸電線路的設計和安全運行提供理論依據。The paper studied withstand voltage level, influence factors, breakdown process and breakdown mechanism of covered with snow or ice through some theory calculation results, many test data and phenomena. the paper got the conclusions that withstand voltage strength of insulator covered with snow or ice descended largely, and the amount of ice or snow build - up, number of flashover, string length, environment temperature and leak current etc had obvious effects on flashover voltage values of insulators
通過大量的試驗數據和現象研究冰雪條件下絕緣子的耐壓水平、影響因素及其擊穿機理，如串長的影響、環境溫度、絕緣子形狀及冰的干濕程度、閃絡次數、冠雪量和積冰量的影響、雪的密度、氣壓和濕度的影響等，並對試驗結果與理論分析結果進行了對比，分析其是否一致。
