Current transformers, inowanzonziCTs, zvakakosha zvikamu mumagetsi emagetsi.Inoita basa rakakosha mukudzivirira uye kuyerwa kwekushandisa, kusiyana neakajairwa ma transformer.Muchikamu chino, tichaongorora mutsauko uripo pakati peCTs uye akajairwa matransformer uye kudzidza mashandisirwo eCTs kudzivirira.
Chekutanga, ngatitarisei mutsauko uripo pakati peCT uye akajairwa kushandura.Traditional transformers anonyanya kugadzirwa kuendesa simba remagetsi pakati pemaseketi nekuwedzera kana kudzikisa voltage level.Inonyanya kushandiswa mukugovera network, voltage inokwidziridzwa kuti itakurwe madaro marefu uye voltage inodzikiswa kuti ishandiswe nevatengi.
Mukupesana ne,zvino transformersdzakanyatsogadzirirwa kuyera kana kutarisa ikozvino kuyerera mumagetsi emagetsi.Inoshanda pamusimboti we electromagnetic induction, yakafanana neyakajairika transformer.Nekudaro, iyo yekutanga mhepo yeCT ine kutendeuka kumwe chete kana kutenderera kwakati wandei, ichibvumira kuti ibatanidzwe munhevedzano neino-inotakura conductor.Iyi dhizaini inogonesa iyoCTkuyera mafungu akakwirira pasina kurasikirwa kukuru kwesimba.Iyo yechipiri mhepo inotenderedza CT inowanzoyerwa kune yakaderera voltage, izvo zvinoita kuti chiridzwa kana chidziviriro chichengetedzeke.
Zvino, ngatienderere mberi kune kukosha kweCT mukudzivirira maapplication.CT inoshandiswa zvakanyanya mumasisitimu emagetsi kuve nechokwadi chekuchengetedzwa kwemidziyo, maseketi uye vashandi.Ivo vanoita basa rakakosha mukuona zvikanganiso, overcurrents uye abnormal kushanda mamiriro.Nekunyatsoyera ikozvino, CT inokonzera chigadziro chekudzivirira chinoparadzanisa chikamu chinokanganisa kubva kune imwe nzvimbo yegadziriro, kudzivirira chero imwezve kukuvara.
Chimbo chekudzivirira chinoshandiswa pamwe chete neCTs is arelay.Iyo relay ine basa rekutarisa kukosha kwazvino uye kutanga kuvhura kana kuvharwa kwedunhu breaker zvichibva pane zvakafanotsanangurwa marongero uye mamiriro.Semuenzaniso, kana dunhu pfupi kana yakawandisa ikozvino ikaitika, relay inoona izvi zvinokanganisa uye inotumira chiratidzo cherwendo kune wedunhu breaker.CTinovimbisa kutirelayinogamuchira kumiririra kwakarurama kwezvino inoyerera kuburikidza nedunhu, zvichiita kuti pave nekuchengetedzwa kwakavimbika.
CTsanoshandiswawo kuyera uye kuongorora magetsi parameters.Mune masisitimu emagetsi, zvakakosha kuti uzive huwandu chaihwo hwezvino inoyerera kuburikidza neakasiyana maseketi.CT inogonesa kuyerwa chaiko, kuve nechokwadi chekutonga kwesimba kwakanaka uye mitoro yakaenzana.Izvi zviyero zvinogona kushandiswa kubhadharisa, kutonga kwesimba uye kuchengetedza kwekudzivirira.
Uyezve, maCT anoshandiswa zvakanyanya mumaindasitiri ekushandisa uye michina ine mikuru mikuru yemagetsi.Ivo vanopa nzira yekutarisa mazinga aripo uye kuona chero anomalies, senge mota yakawandisa kana madonhwe emagetsi.Nekukurumidza kuziva nyaya idzi, matanho ekudzivirira anogona kutorwa kudzivirira kutadza kwemidziyo inodhura kana kuderera.
Muchidimbu, kunyangwe ese ari maviri CT uye anogara achishandura anoshanda pamusimboti we electromagnetic induction, anoshanda zvakasiyana zvinangwa.CTs dzakagadzirirwa iye zvino kuyerwa uye kudzivirira zvikumbiro.Dhizaini yayo yakasarudzika inoigonesa kuyera nemazvo mafungu akakwira uku ichipa yakachengeteka, yakasarudzika goho rezviridzwa uye zvekudzivirira.Kunyangwe kuona zvikanganiso, kuve nechokwadi chekuchengetedzwa kwemagetsi kana kutarisa mashandisirwo emagetsi, CT inoita basa rakakosha mumagetsi emazuva ano masisitimu.Kunyatsogona kuverenga kwazvino uye kuita kwakavimbika kunoita kuti ive chinhu chakakosha mumaindasitiri akasiyana uye maapplication.
