Umgca we-AC ubhekisa kumgca oqhagamshelwe kunikezelo lwamandla lwe-AC okanye iigridi zamandla e-AC ezimbini. Xa kukho umgca we-DC kufuphi nomgca we-AC, umgca we-AC uya kuvelisa i-steady-state power frequency current efakwe kwi-DC yangoku kumgca we-DC ngokusebenzisa i-magnetic induction kunye ne-capacitive coupling.
inkcazelo
Umgca we-AC ubhekisa kumgca oqhagamshelwe kunikezelo lwamandla lwe-AC okanye iigridi zamandla e-AC ezimbini.
Umsinga otshintshanayo (AC) ubhekisa kumbane otshintshayo olathiswayo lwangoku lutshintsha ngamaxesha athile kunye nexesha, kunye nexabiso lomndilili wokusebenza kumjikelo nguziro. Ngokungafaniyo ne-DC, ulwalathiso lwayo luya kutshintsha ngokuhamba kwexesha, kwaye i-DC ayitshintshi ngamaxesha athile.
Ngokuqhelekileyo i-waveform i-sinusoidal. Umsinga otshintshanayo unokuhambisa umbane ngempumelelo. Ngapha koko, kukho ezinye izicelo, ezinje nge-square wave kunye ne-triangular wave. Amandla amakhulu asetyenziswa ebomini atshintshana ngoku kunye ne-sinusoidal waveform.
Ubuninzi bokutshintshana kwangoku kubhekiselele kwinani lotshintsho lwexesha elithile kwixesha leyunithi yalo. Iyunithi yiHertz, ehambelana ngokungafaniyo nomjikelo. Ubuninzi bokutshintshana kwangoku kubomi bemihla ngemihla buqhelekile bungama-50 Hz okanye ama-60 Hz, ngelixa ukuphindaphindeka kokutshintshana kwangoku okubandakanyekayo kubuchwepheshe berediyo bukhulu, bufikelela kumlinganiselo wekhilohertz (kHz) okanye imegahertz (MHz). I-AC frequency yeenkqubo zamandla kumazwe ahlukeneyo yahlukile, ngokuqhelekileyo i-50 Hz okanye i-60 Hz.
UHV AC line
Iinzuzo eziphambili zosasazo lwe-UHV AC zezi:
(1) Ukuphucula umthamo wothumelo kunye nomgama wothumelo. Ngokwandiswa kwendawo yegridi yamandla, umthamo wothumelo kunye nomgama wothumelo lwamandla ombane nawo uyanda. Okukhona iphezulu inqanaba lombane wegridi efunekayo, kokukhona isiphumo sothumelo olubambeneyo lungcono.
(2) Ukuphucula uqoqosho lokuhanjiswa kwamandla. Iphezulu i-voltage yothumelo, iphantsi ixabiso leyunithi nganye yomthamo.
(3) Gcina iipaseji zemigca. Xa sithetha ngokubanzi, enye ye-1150kv yothumelo lwentambo inokutshintsha iintambo ezintandathu ezingama-500kV. Ukusetyenziswa kosasazo lwe-UHV kuphucula izinga lokusetyenziswa kwepaseji.
