altitude camera 中文意思是什麼
altitude camera
解釋
高空照相機-
Test results indicated : with the hoist of altitude, the increase of ice amount and the rise of pollutant, the average flashover voltage reduced. the character exponent generally depends on the insulator profile, ice amount, ice state and pollution severity etc. by means of a high - speed camera, a data acquisition system and high voltage test facilities, a series of the flashover processes on ice surfaces were record. the experimental results form this study and the subsequent theoretical analyses suggested : the thermal ionization of the air in front of an arc root resulted in arc movement ; the electrostatic force had an auxiliary effect of impelling arc propagation ; the electrical
通過對攝像機、數據採集系統及高壓試驗裝置記錄覆冰絕緣子表面閃絡電弧的發展過程的試驗結果進行理論分析得出：弧根周圍空氣的熱電離導致了電弧的發展，靜電場力對電弧的發展起到了加速作用，電擊穿僅發生在閃絡最終的跳躍階段；通過測量閃絡過程中的放電電壓、泄漏電流、閃絡時間、覆冰水電導率、電弧長度及電弧半徑等參數，得到了不同階段電弧（電弧起弧階段、電弧發展階段及完全閃絡）的發展速度、臨界電弧長度均隨覆冰水電導率的增加而減小。 -
