Zogulitsa ndi Mfundo

The LCWD-35 transformer panopa ndi yaying'ono, yaying'ono kukula kwake komanso yopepuka kulemera.Theka lakumtunda ndilo kupiringa koyambirira, theka lakumunsi ndi lopiringizira lachiwiri, tchire limakhazikika pamunsi, pamwamba pa chitsamba chimakhala ndi chosungira mafuta, mafunde oyambira amatsogozedwa mbali zonse za khoma la nduna, ndi poyambira poyambira chizindikiro P1 Kachidutswa kakang'ono ka porcelain amagwiritsidwa ntchito kutsekereza khoma la nduna, ndipo mapeto a P2 amalumikizidwa mwachindunji ndi khoma la nduna.Kutsogolo kwa chosungira mafuta kuli ndi zida zoyezera mafuta zomwe zikuwonetsa kutentha kosiyanasiyana.

Mfundo:
M'mizere yopangira magetsi, malo opangira magetsi, kutumiza, kugawa ndi kugwiritsira ntchito, zamakono zimasiyana kwambiri, kuyambira ma amperes angapo mpaka makumi zikwi za amperes.Kuti muchepetse kuyeza, chitetezo ndi kuwongolera, ziyenera kusinthidwa kukhala zofananira.Kuphatikiza apo, voteji pamzerewu nthawi zambiri amakhala okwera kwambiri, monga kuyeza kwachindunji, komwe ndi koopsa kwambiri.Transformer yamakono imagwira ntchito ya kusintha kwamakono komanso kudzipatula kwamagetsi.
Kwa ma ammeter amtundu wa pointer, mafunde ambiri achiwiri a osinthira apano ali pamlingo wa ampere (monga 5A, etc.).Pazida za digito, chizindikiro chojambulidwa nthawi zambiri chimakhala pamlingo wa milliamp (0-5V, 4-20mA, etc.).Yachiwiri yamakono ya kakang'ono thiransifoma panopa ndi milliampere, amene makamaka amachita ngati mlatho pakati pa thiransifoma lalikulu ndi zitsanzo.
Zosintha zamakono zamakono zimatchedwanso "instrument current transformers".("Chida chamakono chosinthira" chimatanthauza kuti ndi chosinthira chamakono chamitundu ingapo chomwe chimagwiritsidwa ntchito mu labotale, chomwe chimagwiritsidwa ntchito kukulitsa kuchuluka kwa zida.)
Mofanana ndi thiransifoma, thiransifoma yamakono imagwiranso ntchito motsatira mfundo ya electromagnetic induction.Transformer imasintha magetsi ndipo transformer yamakono imasintha panopa.Kumangirira kwa thiransifoma yamakono yolumikizidwa ndi mphamvu yoyezera (chiwerengero cha kutembenuka ndi N1) kumatchedwa mafunde oyambirira (kapena mafunde oyambirira, mapiringidwe oyambirira);Mapiringidwe olumikizidwa ku chida choyezera (chiwerengero cha makhoti ndi N2) amatchedwa mapiringidwe achiwiri (kapena mafunde achiwiri).kukomoka, kukomoka kwachiwiri).
Chiŵerengero chamakono chamakono opangira mphepo I1 ku mphepo yachiwiri I2 ya thiransifoma yamakono imatchedwa chiŵerengero chenicheni chamakono K. Chiŵerengero chamakono cha thiransifoma yamakono pamene chikugwira ntchito pansi pa chiwerengero chamakono chimatchedwa chiŵerengero chamakono cha transformer yamakono. , yofotokozedwa ndi Kn.
Kn=I1n/I2n
Ntchito ya transformer yamakono (CT yaifupi) ndiyo kutembenuza magetsi oyambirira ndi mtengo wokulirapo kukhala wachiwiri wamakono ndi mtengo waung'ono kupyolera mu chiŵerengero china cha kusintha, chomwe chimagwiritsidwa ntchito poteteza, kuyeza ndi zolinga zina.Mwachitsanzo, thiransifoma yamakono yokhala ndi chiŵerengero cha 400/5 ikhoza kutembenuza zenizeni zenizeni za 400A kukhala zamakono za 5A.

Kuthana ndi Vuto la Transformer ndi dongosolo la dongosolo

Kuthana ndi Mavuto Okhudzana ndi Transformer:
Zolephera zamakono za thiransifoma nthawi zambiri zimatsagana ndi phokoso ndi zochitika zina.Pamene dera lachiwiri likutsegulidwa mwadzidzidzi, mphamvu yowonjezereka imapangidwira mu koyilo yachiwiri, ndipo mtengo wake wapamwamba ukhoza kufika ku ma volts oposa zikwi zingapo, zomwe zimaika pangozi moyo wa ogwira ntchito ndi chitetezo cha zipangizo pa dera lachiwiri, ndi high voltage ikhoza kuyambitsa moto wa arc.Panthawi imodzimodziyo, chifukwa cha kuwonjezereka kwamphamvu kwa maginito muzitsulo zachitsulo, imafika pamtunda waukulu.Kutayika kwakukulu ndi kutentha ndizovuta kwambiri, zomwe zingawononge mafunde achiwiri a rheological.Panthawiyi, mafunde osakhala a sinusoidal amayamba chifukwa cha kuwonjezeka kwa mphamvu ya maginito, zomwe zimapangitsa kugwedezeka kwa pepala lachitsulo la silicon kukhala losagwirizana kwambiri, zomwe zimapangitsa phokoso lalikulu.
1. Kusamalira transformer yamakono mu dera lotseguka Ngati cholakwa choterocho chikachitika, katunduyo ayenera kukhala wosasinthika, chipangizo chotetezera chomwe chingakhale chosagwira ntchito chiyenera kutsekedwa, ndipo ogwira nawo ntchito ayenera kudziwitsidwa kuti athetse mwamsanga.
2. Kuchiza kwa thiransifoma yachiwiri kutsekedwa kwa dera (lotseguka dera) 1. Zodabwitsa:
a.Chizindikiro cha ammeter chimatsikira ku zero, chisonyezero cha mphamvu zamagetsi zogwira ntchito ndi zowonongeka zimachepa kapena zimatsika, ndipo mita ya ola la watt imazungulira pang'onopang'ono kapena kuyima.
b.Chenjezo losiyanitsidwa ndi mbale yoyatsira.
c.Transformer yapano imapanga phokoso lachilendo kapena imatulutsa kutentha, kusuta kapena kutulutsa kuchokera ku ma terminals achiwiri, sparks, ndi zina.
d.Chipangizo chotetezera pa relay chikukana kuchitapo kanthu, kapena kulephera (chodabwitsachi chimapezeka kokha pamene wodutsa dera akuyenda molakwika kapena kukana kuyenda ndikuyambitsa ulendo wa leapfrog).
2. Kusamalira kupatula:
a.Nthawi yomweyo nenani chizindikirocho ku ndandanda yomwe ili yake.
b.Malinga ndi chodabwitsa, weruzani ngati thiransifoma yaposachedwa ya dera loyezera kapena dera lachitetezo ndi lotseguka.Kuletsa chitetezo chomwe chingayambitse ntchito yolakwika kuyenera kuganiziridwa musanatayidwe.
c.Mukayang'ana dera lachiwiri la thiransifoma yamakono, muyenera kuyimirira pa insulating pad, kulabadira chitetezo chaumwini, ndikugwiritsa ntchito zida zotetezera zoyenerera.
d.Pamene dera lachiwiri la thiransifoma yamakono likutsegulidwa kuti liyambitse moto, mphamvu iyenera kudulidwa poyamba, ndiyeno moto uyenera kuzimitsidwa ndi nsalu youma ya asbestosi kapena chozimitsira moto chouma.
3. Vuto la thupi la thiransifoma yamakono Pamene cholakwika cha thiransifoma chili ndi chimodzi mwa izi, chiyenera kuyimitsidwa nthawi yomweyo:
a.Pali phokoso lachilendo ndi kutenthedwa mkati, limodzi ndi utsi ndi fungo lopsa.b.Kutaya kwakukulu kwa mafuta, kuonongeka kwa porcelain kapena kutulutsa chodabwitsa.
c.jekeseni wamafuta moto kapena guluu kuyenda chodabwitsa.
d.Elongation wa zitsulo expander kwambiri kuposa mtengo watchulidwa pa kutentha yozungulira.

Dongosolo:
1. Perekani chithunzi cha ndondomeko ya wiring, mawonekedwe a ntchito ndi dongosolo, magetsi ovotera, oveteredwa panopa, ndi zina zotero.
2. Zofunikira pakuwongolera, kuyeza ndi kuteteza ntchito ndi zida zina zotsekera komanso zodziwikiratu.
3. Pamene transformer ikugwiritsidwa ntchito muzochitika zapadera zachilengedwe, ziyenera kufotokozedwa mwatsatanetsatane poyitanitsa.
4. Pamene zida zina kapena zochulukirapo ndi zida zosinthira zikufunika, mtundu wake ndi kuchuluka kwake ziyenera kuperekedwa.
