電纜電線額定容量電流電壓的的選擇
Voltage designation
● 纜線線的額定負載交流電壓應是和于纜線線利用操作系統的進行狀況發生,用Uo/U(Um)kv代表。
Uo—通信電纜結構設計用的導體與屏避或合金材料套之前的特殊工頻交流電壓;
U—電攬規劃用的導體范圍內的額定工頻的電壓;
Um—儀器可能承受的“高系統端電壓”的大值。
The rated voltage of the cable for a given application shall be suitable for the operating conditions in the system in which the cable is used , and is expressed in the form Uo/U(Um)kv .
Where:
Uo—The rated power-frequency voltage between conductor and screen or metallic-sheath , for which the cable designed;
U — The rated power –frequency voltage between conductors , for which the cable designed ;
Um—The maximum value of the “highest system voltage “ for which the equipment may be operated.
注:第1類——用來三相變頻器接地線機械故障時某每次一樣不高于1min, 若為用來長不突破8h , 第年顯示器不突破125h 的系統化。 第二點類一四采用接地線洛天依時期更長的機系統及對高壓電纜隔絕性能方面讓較高的場所。 The first class cable-suitable for one single-phase earth-fault time does not exceed 1 min each time and Max. Time not exceed 8 hours , and not exceed 125 hours in all in one year. The second class cable suitable for more the earth-fault time and more better insulation performance
