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。The main work and conclusion for this paper is as following : according to the flashover test results of several kinds of iced insulators under positive voltage and negative voltage, this paper obtained : for the single porcelain insulator, the single glass insulator and the composite insulator bridged completely by icicle, the metal cathode ' s strong ability of emission electron is the primary reason that results in the lower negative flashover voltage ; the position difference of the high resistance district in method anode side results in that porcelain insulator cluster and glass insulator cluster have an evident effect of polarity ; when less ice and no icicle at the brim of the sheds, due to numerous non - polar arcs on the composite surface, the effects of polarity of composite insulator was lost using the test method of the average flashover voltage in the freezing period, dc flashover performances were investigated of several insulators with some typical structures and different material
本文的主要工作和結論如下:在人工氣候室內,根據不同覆冰絕緣子正、負極性下的閃絡試驗結果,得出負極性電弧金屬陰極的強電子發射能力造成了單片瓷、玻璃絕緣子及被冰凌橋接的合成絕緣子有較低負極性冰閃電壓;正極性電弧金屬陽極側產生高電阻區所處位置的差異使得瓷和玻璃絕緣子串具有明顯的極性效應;覆冰較少時,合成絕緣子表面出現數量較多的非極性電弧使合成絕緣子無極性效應。利用覆冰期內平均閃絡電壓的試驗方法,對不同材質和結構的絕緣子在覆冰、低氣壓和污穢共存環境中的直流閃絡特性進行了研究。試驗結果表明,直流平均閃絡電壓隨著海拔的升高、覆冰量的增加以及污穢度的增加而降低,且其特徵指數與絕緣子結構、覆冰量、覆冰狀態、污穢度等有關。An insulating lift is presented to improve the insulation property between the gripper and ground of high voltage hot - line cleaning robot, and to decrease the initial cylinder ' s working - pressure of vertical lifting mechanism
摘要提出了一種絕緣升降平臺,用於提高高壓帶電清掃機器人帶電作業時的對地絕緣性能,同時降低機器人垂直升降機構驅動油缸的初始工作壓力。Based on a series of tests and investigations, this paper draws some conclusions as following by processing and analyzing the test data. the minimum icing flashover voltage of composite insulators decreases with the increase of ice amount, and the tendency of it accords with exponential function. however, the relation of the minimum icing flashover voltage with icing water conductivity accords with power function
通過大量的試驗研究工作,對試驗數據進行擬合和分析處理,得到了如下結論: 1 )合成絕緣子最低冰閃電壓隨覆冰重量的增加而降低,且其下降趨勢符合指數函數規律,與覆冰水電導率的關系符合冪函數規律。A lot of observation and reports in the world indicated that flashover voltage of insulator covered with snow or ice descended obviously
