flashover test中文什么意思
例句與用法
- General technical specification of test instruments used for power equipments part 1 : fault flashover test instrument for power cable
電力設(shè)備專用測試儀器通用技術(shù)條件.第1部分:電纜故障閃測儀 - On the test investigation , a lot of flashover tests are made in 10kv , 35kv and 63kv voltage condition on post insulators and suspensor insulators , including all conditions covered with snow or ice . which included different environment temperature , different melted ice and melted snow etc multi - condition
試驗(yàn)中，對不同冠雪量、不同覆冰量、不同溫度及不同融冰、融雪等多種情況，環(huán)境溫度在零上幾度，零下十幾度到幾十度等不同情況進(jìn)行了試驗(yàn)。 - 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(jié)論如下：在人工氣候室內(nèi)，根據(jù)不同覆冰絕緣子正、負(fù)極性下的閃絡(luò)試驗(yàn)結(jié)果，得出負(fù)極性電弧金屬陰極的強(qiáng)電子發(fā)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(fù)極性冰閃電壓；正極性電弧金屬陽極側(cè)產(chǎn)生高電阻區(qū)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(yīng)；覆冰較少時，合成絕緣子表面出現(xiàn)數(shù)量較多的非極性電弧使合成絕緣子無極性效應(yīng)。利用覆冰期內(nèi)平均閃絡(luò)電壓的試驗(yàn)方法，對不同材質(zhì)和結(jié)構(gòu)的絕緣子在覆冰、低氣壓和污穢共存環(huán)境中的直流閃絡(luò)特性進(jìn)行了研究。試驗(yàn)結(jié)果表明，直流平均閃絡(luò)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，且其特征指數(shù)與絕緣子結(jié)構(gòu)、覆冰量、覆冰狀態(tài)、污穢度等有關(guān)。
