Kusankha Nameplate: Buku Lotsogolera lathunthu la Zofotokozera za Transformer

Chiyambi

Transformer iliyonse imakhala ndi mbale yachitsulo yomwe imagwira ntchito ngati chizindikiritso chake—dzina lake. Kwa akatswiri ogula zinthu, mainjiniya, ndi oyang'anira katundu, kumvetsetsa izi ndikofunikira. Dzina lake lili ndi ziwerengero zofunika zomwe zimafotokoza momwe transformer ingagwiritsidwire ntchito, kulumikizidwa, ndi kusamalidwa nthawi yonse ya ntchito yake.

Bukuli limatanthauzira magawo ofunikira omwe amapezeka pa ma nameplate a transformer, kufotokoza tanthauzo lililonse ndi chifukwa chake limafunikira pakufotokozera ndi kugula.

Gawo Loyamba: Kuzindikira Transformer ndi Chidziwitso Choyambira

Pamwamba pa dzina lililonse, mupeza dzina la wopanga ndi nambala yapadera ya seri. Nambala iyi ya seri ndi yofunika kwambiri potsatira zolemba za opanga, malipoti a mayeso, ndi zolemba za kapangidwe—makamaka satifiketi yobadwa ya transformer.

Tsiku lopangira (mwezi ndi chaka) nthawi zambiri limaperekedwa, zomwe zimathandiza kuwunika zaka ndi kukonzekera kukonza.

Dzina la chipangizocho lidzafotokoza momveka bwino ngati chipangizocho ndi "transformer" kapena "autotransformer," chiwerengero cha magawo (gawo limodzi kapena atatu), ndi ma frequency ogwirira ntchito (nthawi zambiri 50 Hz kapena 60 Hz).

Gawo Lachiwiri: Mphamvu ndi Voltage Ratings

Mphamvu Yoyesedwa (kVA kapena MVA).Izi zikusonyeza mphamvu yooneka yomwe transformer imatha kupereka mosalekeza pa voltage yovomerezeka komanso pafupipafupi popanda kupitirira malire a kutentha. Kwa transformers zomwe zili ndi magawo ambiri ozizira, ziwerengero zosiyanasiyana zitha kuwonetsedwa pa mtundu uliwonse.

Ma Voltage Ratings.Chidziwitso cha magetsi chimawonekera mu mtundu winawake. Mwachitsanzo, "230000GR.Y / 132800-69000GR.Y / 39840-12470" ikusonyeza:

• Kuzungulira kwamphamvu kwamagetsi: 230,000 V mzere kupita ku mzere, Y yokhazikika, 132,800 V gawo-mpaka-neutral
• Kuzungulira kwamagetsi otsika: 69,000 V mzere kupita ku mzere, Y yokhazikika, 39,840 V gawo-mpaka-neutral
• Kuzungulira kwapamwamba: 12,470 V yolumikizidwa ndi delta

Pamene slash ikuwonekera, imalekanitsa voltage ya mzere kupita ku mzere kuchokera ku voltage ya gawo kupita ku neutral. GR.Y kapena Grd.Y zimasonyeza kuti neutral ikufuna kukhazikika pansi-1.

Chidziwitso Chokhudza Kukhudza.Kwa ma transformer okhala ndi zosinthira ma tap, tebulo la chiŵerengero cha ma voltage limasonyeza ma voltage pamalo aliwonse opopera, zomwe zimathandiza ogwiritsa ntchito kusankha malo oyenera a machitidwe a dongosolo.

Gawo Lachitatu: Deta Yopanda Kutha ndi Kutayika

Peresenti ya Kulephera kwa Mphamvu (%Z).Gawo lofunika ili, lomwe limafotokozedwa ngati peresenti, limasonyeza kutsika kwa magetsi pakadzaza katundu. Limakhudza mafunde afupikitsa komanso malamulo a magetsi. Ma mtengo wamba amakhala pakati pa 4% mpaka 15% kutengera kukula kwa transformer. Peresenti ya impedance imatchulidwa pakati pa ma windings awiri aliwonse, ndi maziko a kVA omwe atchulidwa.

Kutaya Kopanda Katundu (Kutaya Chitsulo).Kutayika kumeneku kumachitika nthawi zonse nthawi iliyonse transformer ikapatsidwa mphamvu, mosasamala kanthu za katundu. Kumachitika chifukwa cha maginito pakati ndipo kumagwirizana kwambiri ndi ubwino wa zinthu zapakati.

Kutaya Katundu (Kutayika kwa Mkuwa).Kutayika kumeneku kumasiyana malinga ndi sikweya ya mphamvu ya katundu ndipo kumachitika mu ma windings chifukwa cha kukana. Kutayika kochepa kwa katundu kumatanthauza kugwira ntchito bwino kwambiri munthawi yodzaza katundu.

Gawo Lachinayi: Kuziziritsa, Kutentha, ndi Chidziwitso Cholumikizira

Kalasi Yoziziritsira.Ma transformer amagwiritsa ntchito ma code ovomerezeka posonyeza njira zoziziritsira. Pa mayunitsi oviikidwa mu mafuta, mayina monga ONAN (Oil Natural Air Natural) kapena ONAF (Oil Natural Air Forced) amafotokoza njira zoziziritsira zamkati ndi zakunja komanso njira zoyendera. Transformer Youmas, ma code monga AN (Air Natural) kapena AF (Air Forced) amagwiritsidwa ntchito.

Kukwera kwa Kutentha.Izi zikusonyeza kukwera kwakukulu kwa kutentha kuposa malo omwe transformer imatha kupirira mosalekeza, nthawi zambiri 55°C kapena 65°C pamayunitsi oviikidwa mu mafuta. Kalasi yotetezera kutentha (A, B, F, H) imasonyeza kutentha kwakukulu kovomerezeka kogwira ntchito.

Chithunzi cha Vector Group ndi Connection.Pa ma transformer a polyphase, chithunzi cha vector chikuwonetsa ubale wa gawo pakati pa ma windings oyambira ndi achiwiri. Maina wamba monga Dyn11 amasonyeza delta primary, wye secondary with neutral, ndi kusintha kwa gawo la madigiri 30. Chithunzi cha schematic chikuwonetsa kulumikizana konse kwamkati ndi zizindikiro za terminal.

Gawo Lachisanu: Chidziwitso Chakuthupi ndi Chitetezo

Kulemera ndi Kuchuluka kwa Mafuta.Mapepala olembera mayina nthawi zambiri amalemba kulemera kwa core ndi coils, thanki ndi zolumikizira, mafuta otetezera kutentha, kulemera konse, ndi chidutswa cholemera kwambiri chonyamulira. Kuchuluka kwa mafuta ndi mtundu wa madzi otetezera kutentha kumatchulidwanso.

Magawo Oteteza.Mulingo Woyambira wa Kuteteza Mphamvu ya Mphepo (BIL) umasonyeza kuthekera kwa transformer kupirira ma voltages othamanga, omwe amafotokozedwa pa kuzungulira kulikonse.

Mlingo wa Phokoso.Ma nameplate ena amaphatikizapo ma rating a mawu mu ma decibel, omwe amayesedwa pa mtunda wokhazikika. Izi ndizofunikira kwambiri pa malo omwe amakhudzidwa ndi phokoso monga madera okhala anthu kapena zipatala.

Mapeto

Dzina la transformer si chizindikiro chophweka—ndi chikalata chaukadaulo chokwanira chomwe chimafotokoza mphamvu ndi zofooka za katunduyo. Kwa akatswiri ogula zinthu, kumvetsetsa momwe angawerengere ndikutanthauzira izi kumatsimikizira kuti zinthuzo ndi zolondola, kumapewa zolakwika pakugwira ntchito, komanso kumathandiza kusankha bwino zinthu zokhudza kusankha ndi kugwiritsa ntchito transformer.
