This article, which researches on composite insulators " ac flashover characteristic in high altitude and ice environment, has significant science values in theory and can also create enormous economy benefit in engineering
因此本文研究合成絕緣子在高海拔和覆冰地區的交流閃絡特性在理論上具有非常重要學術價值，在工程上能夠創造巨大的經濟效益。With regard to the special environment of high altitude and ice, this paper mainly studies the effect of altitude ( air pressure ), icing states ( ice amount ) and icing water conductivity on the ac flashover characteristic of composite insulators. furthermore, it analyzes the hydrophobicity of composite insulators in these environments
針對高海拔和覆冰地區特殊的環境，本文重點研究海拔高度（即氣壓） 、覆冰程度及覆冰水電導率等對合成絕緣子交流閃絡特性的影響，並且對合成絕緣子在高海拔和覆冰環境下的表面憎水性變化進行分析。Given the present unusual global warming rate on an already warm planet, we can anticipate that areas with summer melt and rain will expand over larger areas of greenland and fringes of antarctica
在已經很暖的地球加上現在不尋常的全球暖化速率，我們可以預期，在格陵蘭與南極的邊緣，夏季融冰與降雨的地區會大幅擴張。All the transmission lines of west - east electricity transmitting project are inevitable to crossing the high altitude and icing areas. for the reducing of the air pressure and the absolute humidity, the electricity strength of insulators will drop obviously. therefore, it must be considered the effect on the insulators " flashover voltage caused by the change of altitude and ice when the insulation cooperation of transmission lines are being designed
「西電東送」工程的所有輸電線路都不可避免的要經過高海拔和覆冰地區，由於大氣壓力和絕對濕度的降低會使絕緣子的電氣強度顯著下降，因此在進行輸電線路的絕緣配合設計時必須考慮到海拔高度和覆冰的變化對絕緣子的閃絡電壓影響。On the condition of insulator covered in snow or ice chill climate area of northeast in china, many accidence of insulation flashover occurred which brought prodigious damage for electric power system and loss for economic
國內東北地區在寒冷氣候條件下覆冰覆雪時曾發生過多次閃絡和絕緣擊穿事故，造成極大危害和經濟損失。Discovery of frost riving structure at the ice front of holocene in duolun district inner mongolian autonomous region and its significance
內蒙古多倫地區全新世冰緣融凍構造的發現及其意義The iced insulators flashover is one of the main faults of the ehv transmission lines in icing regions. icing is especial form of pollution
對覆冰地區的超高壓線路，絕緣子覆冰引起的閃絡已經成為最主要的故障之一，對電力系統的安全運行造成了極大的威脅。Based on a great of laboratory investigation carried out on the ac flashover performance of several types of insulators in the multi - function artificial climate chamber of chongqing university, this paper studies systematically the ac flashover performance of several type of insulators and puts forward a flashover voltage correction method for the atmospheric environment at altitude of 3500 m above, and discusses the flashover process and mechanism of the iced insulator
本文在國內外現有研究成果的基礎上，通過大量的人工氣候室模擬試驗研究和理論分析，對海拔3500m以上地區覆冰和污穢絕緣子的交流閃絡特性及閃絡電壓的校正方法進行了系統研究，並對覆冰合成絕緣子的閃絡過程和機理進行了初步探討。And during the little ice age ). the main discrepancy of climatic and environmental changes of the southern margin of tarim basin and the eastern region of china appeared to be the collocation patterns which were the synchronism in cold or warm conditions and the difference in hydrological conditions. meanwhile, the discoveries of abrupt climate changes in the past have raised an urgent request for paleoclimatic and paleoenvironmental records
（ 2 ） 、中全新世氣候適宜期（ 6 . 7 3 . 0kab . p . ）尤其是近4 . 0ka以來及小冰期，南疆塔里木盆地南緣與我國東部季風區存在著冷、暖同步，干、濕相異的特徵；並以相對冷濕? ?相對暖乾的演變模式與我國東部季風區的相對冷干? ?相對暖濕的特徵相區別。分享友人
