起電暈電壓 的英文怎麼說
中文拼音 [qǐdiànyūndiànyā]
起電暈電壓
英文
corona voltage-
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。And the inception voltage decrease with reduction of air pressure ( increase of altitude )
起暈電壓隨著氣壓的降低(海拔高度的增加)而降低。The results indicate that there is an obvious effect of air gap and ice state on the inception voltage across the air gap
研究結果表明:間隙長度、冰的狀態和氣壓對間隙的起暈電壓有明顯的影響。The longer the air gap is, the higher the inception voltage ; the inception voltage is lower with 2kv at wet ice than dry ice. while, there is not a distinct effect of water conductivity on the initiative voltage
間隙越長,起暈電壓越高;濕冰情況下間隙的起暈電壓比乾冰約低2kv ;而覆冰水電導率對起暈電壓沒有明顯的影響。分享友人
