Sidee loo tijaabiyaa AC hipot cable fiilada danab yar (LV) oo ku salaysan heerka IEC?
Xadhkaha hoose -waxaa loo baahan yahay in lagu go'aamiyo iyada oo lagu salaynayo cabbirada sida nooca fiilada iyo danabka la qiimeeyey si waafaqsan heerarka IEC (sida taxanaha IEC 60502) marka warshada fiilada ay samayso tijaabada hipot AC.
1. Tijaabi danab:
Iyadoo lagu salaynayo danab lagu qiimeeyay fiilada (U0), tamarta tijaabada wershadu inta badan waa 3.5 jeer U0 (tusaale ahaan, fiilada leh danab lagu qiimeeyay 0.6/1 kV, U0=0.6 kV, iyo danabku waa 2.1 kV). Qiimahani waxa uu ka sarreeyaa heerka tijaabada ka hortagga si loo xaqiijiyo waxqabadka dahaadhka wakhtiga wax soo saarka warshadda.
2. Waqtiga tijaabada:
Tijaabada ka-hortagga ah ee tijaabada AC hipot ee fiilada LV ee Shiinaha GB 50150 waxay qabataa koronto 2.5 jeer U0 ah 60 daqiiqo, iyadoo ku saleysan heerka IEC, warshadda fiilada LV waxay xooga saaraysaa xaqiijinta gaaban{4}} muddada sare-(3.5 jeer U0 15 daqiiqo)
3. Inta jeer ee tijaabada:
Korontada inta jeer ee warshadaha (50/60Hz) ama soo noqnoqoshada isbedbeddelka ah ee u dhaxaysa 20 ilaa 300Hz. Marka hore in la isticmaalo inta jeer ee warshadaha. Haddii qalabku xaddidan yahay, ka dib isticmaal inta jeer ee doorsoomayaasha, laakiin hubi tayada waveform.
