功能豐富:起始/收弧電流、上升/下降時間、基值電流、峰值電流、脈沖頻率、占空比、滯后關氣時間分別可調,高頻/接觸引弧、水冷/氣冷可供選用。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。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。Turn your body to the right. thrust your right fist up and forward in front of your chest, knuckles turned down, lower your left hand to the side of your left hip, with the palm turned downward and the fingers pointing forward. at the same time, draw back your right foot and, without stopping or allowing it touch floor, take a step to 10 oclock with the toes turned out
