Q&A
Tsis tshua muaj hluav taws xob tam sim no ua rau kev laus ntawm cov hlau nruab nrab, ua rau muaj hluav taws kub. Qhov no feem ntau yog tshwm sim los ntawm qhov tseem ceeb tam sim no tsim los ntawm peb -theem imbalance thiab harmonic tam sim no los ntawm nonlinear loads. Tam sim no ntws los ntawm tus neeg xyuas pib tsim cov cua sov, uas yog proportional rau square ntawm tam sim no (12R). Thaum qhov tam sim no nce mus txog 1.5 npaug ntawm theem tam sim no, cov cua sov tsim tawm hauv cov hlau nruab nrab tuaj yeem ncav cuag 2.25 npaug ntawm theem xaim! Tsis tas li ntawd, nyob rau hauv cov kab hluav taws xob ib txwm muaj (TN-C, TN-S), txawm hais tias muaj cov khoom siv tiv thaiv overcurrent ntawm cov xov hlau theem, tsis muaj ib qho ntawm cov xov hlau nruab nrab. Tshaj tam sim no yuav inevitably ua rau kev laus ntawm lub nruab nrab hlau rwb thaiv tsev, ua rau muaj kev nyab xeeb.
