The relative air density decreases with the increasing of altitude. therefore, the discharge performance of air - gap and insulator string at high altitude regions is different from that of the referring standard conditions
高海拔地區相對空氣密度較低,絕緣子和空氣間隙的放電特性與低海拔地區有很大的差異。Electrical field stress at the icicle tips is even stronger. at these areas, if the electric field across air gaps is high enough, corona discharges are initiated. this can lead to the development of local arcs across the air gaps causing a substantial increase in leakage current and a concomitant melting of ice
空氣間隙的存在使覆冰絕緣子表面的電場分佈發生了明顯畸變,間隙上承受了非常高的電壓,這使得冰凌尖端的電場變得相當強,一旦電場達到了電暈的起始電場,局部放電就在這一區域發生,進而產生局部電弧並逐漸發展成整串的閃絡,泄漏電流迅速增大,同時伴隨著冰的融化。The main works and conclusions in this paper are as follows : make three kinds of models and corresponding electrode system to simulate corona discharge, surface discharge and cavity discharge. in double shielding room, a large number of experiments were done on these models. lots of experimental data were obtained
本文的主要工作和結論如下:製作了電暈放電模型、氣隙放電模型、沿面放電模型和相應電極,在實驗室中模擬空氣中電暈放電、油中電暈放電、固體絕緣內氣隙放電、空氣中沿面放電和油中沿面放電這五種絕緣缺陷。Surface flashover across the insulators in vacuum is the major limitation of the performance of the high power system, such as high power microwave tube, pulse power switch, high - energy linear accelerator, etc. flashover studies are of considerable importance in many applications. alumina ceramics are used widely in vacuum insulation system. the flashover and charging performance have been systematically investigated on alumina ceramics in vacuum under pulse voltage ( 0. 7 / 4 ^ 8 )
真空中絕緣子沿面閃絡現象是制約高功率微波管、脈沖功率開關、高能粒子加速器等系統性能的主要原因,這是因為真空中絕緣子在一個比自身及相同真空間隙擊穿電場低得多的電場下就發生了表面閃絡的緣故,研究真空中絕緣子沿面閃絡現象及其形成機理對于改善和提高系統性能有重要意義。The existence of air gaps will inevitably distort strongly electrical field distribution and cause to a significant voltage drop across the gap, which causes severely non - uniform electrical field near the icicle top
運行和試驗研究表明,絕緣子串在運行電壓或試驗電壓下覆冰時其高壓端總是存在空氣間隙。So, based on the important project, the discharge performance of short rod - plane air gaps and short insulator strings has been researched in this dissertation, which there is not only very important value of engineering application but also very important value of learning
因此,結合西部大開發的重點工程建設需要,論文選擇海拔4000m以上大氣條件下空氣間隙和絕緣子放電特性作為研究課題,具有重要的工程應用價值和學術意義。Power transformers part 3 : insulation levels, dielectric tests and external clearances in air

因此,深入、系統的研究空氣間隙中的放電活動對絕緣子串閃絡電壓的影響有著重要的工程應用價值和學術意義。The study works and conclusion of the dissertation is followed as : the discharge voltage of short rod - plane air gaps and short insulator strings will also decrease with the altitude increasing or atmospheric pressure decreasing, but the decreasing trend is relative to the scale of altitude, the decreasing speed of discharge voltage is slower in the high altitude region
論文的研究工作和成果主要有: 「棒板」典型間隙和絕緣子短串的放電電壓均隨海拔的升高而降低,且其降低的趨勢與海拔高度的范圍有關,海拔越高降低的速度越緩慢。氣壓的變化反映了海拔高度的變化及其相應海拔下空氣溫度、濕度和相對密度的變化。The change of atmospheric pressure reflect the change of the altitude and the change of the temperature 、 humidity and relative air density in the different altitude region, so the atmospheric pressure is able to be use for the characteristic parameter of token the effect of the altitude on external
氣壓可作為表徵海拔高度對外絕緣放電電壓影響的特徵參數;高海拔地區空氣間隙和絕緣子串的放電電壓u均可表示為相應海拔下氣壓的冪函數,即u = u0 ( p / p0 ) n ,其中氣壓對放電電壓影響的特徵指數n與電壓類型和放電間隙的結構類型以及絕緣子類型等有關。分享友人
