Ma transformer apano, nthawi zambiri amatchedwaCTs, ndi zigawo zofunika mu machitidwe a mphamvu.Zimagwira ntchito yofunika kwambiri pakuteteza ndi kuyeza, mosiyana ndi zosinthira wamba.M'nkhaniyi, tiwona kusiyana pakati pa ma CT ndi ma transformer wamba ndikuphunzira momwe ma CT amagwiritsidwira ntchito kuteteza.
Choyamba, tiyeni tifufuze kusiyana pakati pa CT ndi ma transformer wamba.Ma transfoma achikhalidwe amapangidwa kuti azitha kusamutsa mphamvu zamagetsi pakati pa mabwalo powonjezera kapena kuchepetsa mphamvu yamagetsi.Zomwe zimagwiritsidwa ntchito kwambiri pamagawo ogawa, magetsi amakwezedwa kuti atumize mtunda wautali ndipo magetsi amatsitsidwa kuti agwiritse ntchito ogula.
Motsutsana,thiransifoma zamakonoadapangidwa makamaka kuti aziyezera kapena kuyang'anira momwe akuyenderera mumayendedwe amagetsi.Zimagwira ntchito pa mfundo ya electromagnetic induction, yofanana ndi thiransifoma wamba.Komabe, kupindika koyambirira kwa CT kumakhala ndi kutembenuka kumodzi kapena kutembenuka kangapo, kulola kuti ilumikizidwe motsatizana ndi kondakitala wonyamula pakali pano.Kapangidwe kameneka kamathandizaCTkuyeza mafunde apamwamba popanda kutaya mphamvu kwakukulu.Mapiritsi achiwiri a CT nthawi zambiri amavotera mphamvu yocheperako, zomwe zimapangitsa chida kapena chipangizo choteteza kukhala chotetezeka.
Tsopano, tiyeni tipitirire ku kufunikira kwa CT pakugwiritsa ntchito chitetezo.CT imagwiritsidwa ntchito kwambiri pamakina amagetsi kuti zitsimikizire chitetezo cha zida, mabwalo ndi ogwira ntchito.Amagwira ntchito yofunika kwambiri pozindikira zolakwika, ma overcurrents ndi zochitika zachilendo zogwirira ntchito.Poyesa molondola pakali pano, CT imayambitsa chipangizo chotetezera chomwe chimasiyanitsa mbali yolakwika ndi dongosolo lonse, kuteteza kuwonongeka kwina kulikonse.
Chipangizo chodzitetezera chomwe chimagwiritsidwa ntchito limodzi ndi CTs ndikutumiza.Relay ili ndi udindo woyang'anira mtengo wamakono ndikuyambitsa kutsegula kapena kutseka kwa woyendetsa dera kutengera makonda ndi zikhalidwe zomwe zafotokozedwa.Mwachitsanzo, ngati kagawo kakang'ono kapena kopitilira muyeso kumachitika, cholumikizira chimazindikira izi ndikutumiza chizindikiro chaulendo kwa wophwanya dera.CTzimatsimikizira kutikutumizaamalandira chisonyezero cholondola cha zomwe zikuyenda mozungulira dera, zomwe zimapangitsa chitetezo chodalirika.
CTsamagwiritsidwanso ntchito kuyeza ndi kuyang'anira magawo amagetsi.M'makina amagetsi, ndikofunikira kudziwa kuchuluka kwazomwe zikuyenda m'mabwalo osiyanasiyana.CT imathandizira miyeso yolondola, kuwonetsetsa kuyendetsa bwino kwa mphamvu ndi katundu wokwanira.Miyezo iyi itha kugwiritsidwa ntchito polipira, kuwongolera mphamvu komanso kukonza zodzitetezera.
Kuphatikiza apo, ma CT amagwiritsidwa ntchito kwambiri m'mafakitale ndi makina okhala ndi magetsi akuluakulu.Amapereka njira yowunikira milingo yomwe ilipo ndikuwona zolakwika zilizonse, monga kuchulukira kwagalimoto kapena kutsika kwamagetsi.Pozindikira mwachangu zovuta izi, njira zodzitetezera zitha kuchitidwa kuti zida zowononga zidawonongeka kapena kutsika kwanthawi yayitali.
Mwachidule, ngakhale ma CT ndi ma transformer okhazikika amagwira ntchito pa mfundo ya electromagnetic induction, amagwira ntchito zosiyanasiyana.Ma CT amapangidwa kuti azigwiritsidwa ntchito poyezera komanso chitetezo.Kapangidwe kake kapadera kamapangitsa kuti athe kuyeza molondola mafunde apamwamba pomwe akupereka zotetezedwa, zodzipatula za zida ndi zida zodzitetezera.Kaya tikuwona zolakwika, kuwonetsetsa chitetezo chamagetsi kapena kuyang'anira momwe magetsi amagwiritsidwira ntchito, CT imagwira ntchito yofunika kwambiri pamagetsi amakono.Kuthekera kwake powerenga bwino komanso magwiridwe antchito odalirika kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale ndi ntchito zosiyanasiyana.
