PT neCT muTransformers: Magamba Asingaimbirwi eVoltage neCurrent

Kana zvasvika kune ma transformer,PT(Chinoshanduka Chinogona KuitikauyeCT(Current Transformer) vakaita sevari vaviri vane simba remagetsi—Batman naRobin. Vangasanyanya kukoshesa magetsi sezvakaita transformer pachayo, asi vaviri ava vanoshanda vari panze kuti vave nechokwadi chekuti zvese zvinofamba zvakachengeteka uye zvinobudirira. Ngationgororei mashandiro avanoita mashiripiti avo muzvigadziriso zvakasiyana zve transformer.

PT: Mutauriri weVoltage

IyoTransformer Inokwanisa Kushandiswa (PT)ndiyo nzira yaunonyanya kufarira yekudzika voltage yakakwira kusvika padanho rinogoneka. Fungidzira uri kubata ne33 kV (kana kutopfuura) musystem yako yemagetsi—ine njodzi uye zvechokwadi haisi chinhu chaungade kuyera zvakananga. Ndipo panopinda PT. Inoshandura mavoltage iwayo anokwidza bvudzi kuita chimwe chinhu chinogona kugadziriswa nemameter ako uye marelay pasina kudikitira, kazhinji ichidzikiswa kusvika pa110 V kana 120 V.

Saka, unowana kupi PTs dziri kushanda?

• Matransformer emagetsi ane simba guru: Idzi ndidzo pfuti huru dzemagetsi, dzinobata mavoltage kubva pa110 kV kusvika pa765 kV. MaPT pano anoita shuwa kuti unogona kutarisa nekuyera voltage zvakachengeteka uri kure.
• Matransformer ezviteshi zvepasi: MaPT anoshanda muzviteshi zvemagetsi kuti atarise uye adzore huwandu hwemagetsi asati agoverwa kune vatengi vemaindasitiri kana vekugara.
• Dziviriro uye metering transformers: Mumasystems uko kutarisa voltage kwakakosha pakuchengetedza uye kubhadhara, maPT anopindira kuti ape kuverenga kwakarurama kwevoltage yemakamuri ekudzora, marelay, uye zvishandiso zvekudzivirira.

PT yakaita semuturikiri akadzikama, akaunganidzwa pakonzati yemagetsi ine ruzha, achitora manotsi e110 kV anotsemura nzeve oashandura kuita ruzha runyoro runogona kubatwa nemidziyo yako.

CT: Mutongi weParizvino

Zvino, ngatitaurei nezveTransformer Yazvino (CT), chirairidzi chemagetsi chega. Kana magetsi atanga kuchinjisa tsandanyama dzawo nezviuru zvemaamps zvichiyerera nepa transformer yako, CT inopindira kuti idzore kusvika padanho rakachengeteka—kazhinji pa5 A kana 1 A.

Uchawana maCT achitandara mu:

• Transformer yekugoveras: Varume ava vanoshanda munzvimbo dzekugara kana dzekutengeserana, vanowanzo shanda pamagetsi akaita se11 kV kusvika 33 kV. MaCT pano anovimbisa kutariswa nekuchengetedzwa kwemagetsi, achitarisa kuti mvura yakawanda sei iri kuyerera mumitsetse.
• Masimba Anoshandura muzviteshi zvepasi: MaCT anotarisa magetsi ari pazviteshi zvemagetsi zvine simba guru apo matransformer anodzikisa magetsi kubva pamatanho ekutumira magetsi (semuenzaniso, 132 kV kana kupfuura) kusvika pamatanho ekugovera magetsi. Akakosha pakuona zvikanganiso uye midziyo yekudzivirira isati yatanga kushanda.
• Matransformer emaindasitiri: Mumafekitori kana munzvimbo dzemaindasitiri makuru, matransformer anowanzo takura zvinhu zvinorema, uye maCT aripo kuti aongorore mafungu makuru. Kana chimwe chinhu chikafamba zvisina kunaka, CT inotumira ruzivo kumasisitimu ekudzivirira anovhara zvinhu michina isati yagochwa.

Funga nezveCT semutyairi webhasikoro — inochengetedza magetsi kuti asakurire dziviriro yako, uye kana zvinhu zvikanyanya kusagadzikana, CT inoita shuwa kuti mumwe munhu anosvika panzvimbo yekumira yekukurumidza.

Nei PT neCT Zvichikosha

Pamwe chete, PT neCT vanoumba vaviri vepamusoro-soro vemakombi e transformer munyika. Ndivo vanoita kuti vashandi vagone kutarisa nekutonga mashandiro e transformer pasina kufanira kusvika kune chikara (ndivimbei, hamudi kusvika pedyo nerudzi irworwo rwemagetsi nemagetsi pasina dziviriro yakakomba). Ingava iritransformer yekugoveramunharaunda yako kana kutitransformer yesimba rine simba guruSimba remagetsi rinopa simba mumaguta ese, maPT nemaCT anogara aripo, zvichiita kuti voltage nemagetsi zvirambe zviri mugwara.

Wakambozvibvunza here kuti sei bhiri rako remagetsi rakarurama kudaro? Unogona kutenda maCT nemaPTs mumatransformer ekuyeraVanova nechokwadi chekuti kambani yemagetsi nemutengi vanoziva kuti magetsi akawanda sei ari kushandiswa nekudzika pasi nemazvo uye kuyera voltage ne current. Saka, hongu, PT ne CT zviri kuchengetedza zvinhu zvakaenzana kumativi ese e power grid.

Mhedziso

Saka, ingave transformer refu yekutumira magetsi kana transformer inoshanda nesimba yekuparadzira magetsi,PT neCTndiwo magamba asina kurumbidzwa anoramba achiita kuti zvese zvifambe zvakanaka. Anodzikamisa magetsi akawanda uye magetsi makuru kuitira kuti vanoashandisa, marelay, uye mamita vagone kuzvibata vasina sutu yesuperhero. Nguva inotevera paunobatidza switch yemwenje, yeuka—kune timu yese yevanochengetedza magetsi vari kuona kuti magetsi nemagetsi zvinofamba zvakanaka.
