Kugadzirisa Nameplate: Gwaro Rakazara reTransformer Specifications

Nhanganyaya

Transformer yega yega ine ndiro yesimbi inoshanda sechitupa chayo—zita rekuti. Kune nyanzvi dzekutenga, mainjiniya, uye vatariri vemidziyo, kunzwisisa ruzivo urwu kwakakosha. Zita rekuti transformer rine nhamba dzakakosha dzinotsanangura kuti transformer inogona kushandiswa sei, kubatanidzwa, uye kuchengetwa sei muhupenyu hwayo hwese hwekushanda.

Gwaro iri rinoongorora maparamita akakosha anowanikwa pamanameplate etransformer, richitsanangura zvinoreva chimwe nechimwe uye kuti nei chichikosha pakutsanangurwa uye kuwanikwa.

Chikamu Chekutanga: Kuzivikanwa kweTransformer uye Ruzivo Rwekutanga

Pamusoro pezita rega rega, muchawana zita remugadziri uye nhamba yeserial yakasiyana. Nhamba iyi yakakosha pakutevera zvinyorwa zvekugadzira, mishumo yebvunzo, uye magwaro ekugadzira—zvikurukuru chitupa chekuzvarwa chetransformer.

Zuva rekugadzira (mwedzi negore) rinowanzo kupihwawo, zvichiita kuti pave nekuongorora zera uye kuronga kugadzirisa.

Zita rekuti "nameplate" richaratidza zvakajeka kana unit yacho iri "transformer" kana kuti "autotransformer," huwandu hwezvikamu (chikamu chimwe chete kana zvitatu), uye frequency yekushanda (kazhinji 50 Hz kana 60 Hz).

Chikamu Chechipiri: Simba uye Voltage Ratings

Simba Rakayerwa (kVA kana MVA).Izvi zvinoratidza simba rinoonekwa iro transformer inogona kupa nguva dzose pamagetsi akayerwa uye frequency pasina kudarika miganhu yekupisa. Kune ma transformer ane matanho akawanda ekutonhodza, zviyero zvakasiyana zvinogona kuratidzwa kune imwe neimwe mode.

Kuyera Voltage.Ruzivo rwemagetsi (voltage) rwunoonekwa muchimiro chakati. Semuenzaniso, "230000GR.Y / 132800-69000GR.Y / 39840-12470" inoratidza:

• Kutenderedza kwemagetsi ane simba guru: 230,000 V mutsetse-ku-mutsetse, Y yakadzika, 132,800 V phase-to-neutral
• Kutenderedza kwemagetsi mashoma: 69,000 V line-to-line, grounded Y, 39,840 V phase-to-neutral
• Kutenderera kwechitatu: 12,470 V delta-yakabatana

Kana slash yaonekwa, inoparadzanisa voltage yemutsara kubva pamagetsi echikamu kuenda kune asina kusimba. GR.Y kana Grd.Y zvinoratidza kuti neutral yakagadzirirwa kugadzikwa pasi-1.

Kubata Ruzivo.Kune matransformer ane mapombi ekuchinja, tafura yehuwandu hwemagetsi inoratidza voltage panzvimbo yega yega yekupomba, zvichibvumira vashandisi kusarudza mamiriro akakodzera emamiriro esystem.

Chikamu Chechitatu: Impedance uye Data Rokurasikirwa

Percent Impedance (%Z).Iyi parameter inokosha, inoratidzwa sepercentage, inoratidza kudonha kwevoltage pakuzara kwemagetsi. Inokanganisa ma short-circuit currents uye kudzorwa kwevoltage. Zvakajairika zvinotangira pa4% kusvika 15% zvichienderana nehukuru hwetransformer. Percentage impedance inotsanangurwa pakati pemawiri ese emawindings, nekVA base yakataurwa.

Kurasikirwa Nemutoro (Kurasikirwa Nesimbi).Kurasikirwa uku kunoitika nguva dzose pese panoshandiswa simba re transformer, pasinei nemutoro. Kunokonzerwa nekuita kuti core core ishande nemagineti uye kwakabatana zvakanyanya nehunhu hwe core tool.

Kurasikirwa Nemutoro (Kurasikirwa Nemhangura).Kurasikirwa uku kunosiyana zvichienderana nehukuru hwemutoro uye kunoitika mumawindings nekuda kwekusagadzikana. Kurasikirwa kushoma kwemutoro kunoreva kushanda zvakanaka kwakanyanya mumamiriro ezvinhu akaremerwa.

Chikamu Chechina: Ruzivo rweKutonhodza, Tembiricha, uye Kubatana

Kirasi Yekutonhodza.Matransformer anoshandisa makodhi akajairwa kuratidza nzira dzekutonhodza. Kune mayuniti anonyudzwa mumafuta, mazita akaita seONAN (Oil Natural Air Natural) kana ONAF (Oil Natural Air Forced) anotsanangura nzira dzekutonhodza dzemukati nedzekunze uye nzira dzekutenderera. Transformer yerudzi rwakaomas, makodhi akaita seAN (Air Natural) kana AF (Air Forced) anoshandiswa.

Kukwira kweTembiricha.Izvi zvinotsanangura kuwedzera kwakanyanya kwekushisa pamusoro pemamiriro ekunze ayo transformer inogona kutsungirira nguva dzose, kazhinji 55°C kana 65°C yemayuniti akanyikwa mumafuta. Kirasi yekudzivirira kupisa (A, B, F, H) inoratidza tembiricha yepamusoro inobvumirwa kushanda.

Vector Group neConnection Diagram.Kune ma polyphase transformers, dhayagiramu yevector inoratidza hukama hwechikamu pakati pema windings ekutanga neechipiri. Mazita akafanana seDyn11 anoratidza delta primary, wye secondary isina neutral, uye 30-degree phase shift. Dhayagiramu ye schematic inoratidza zvese zvinobatanidzwa mukati uye zviratidzo zve terminal.

Chikamu Chishanu: Ruzivo rweMuviri neKuchengetedzeka

Kurema uye Huwandu hweOiri.Mapureti emazita anowanzo ratidza huremu hwepakati nepakati pemakoiri, tangi nemidziyo yekuisa zvinhu, mafuta ekuisa zvinhu zvinodzivirira kupisa, huremu hwese, uye chinhu chinorema zvikuru chekusimudzira. Huwandu hwemafuta nerudzi rwemvura inoisa zvinhu zvinodzivirira kupisa zvinotsanangurwawo.

Mazinga ekudzivirira kupisa.Nhanho yeBasic Lightning Impulse Insulation Level (BIL) inoratidza kugona kwetransformer kutsungirira ma voltage ekukwira, akatarwa pa winding yega yega.

Ruzha rweRuzha.Mamwe ma nameplates ane manzwi akaenzana nema decibel, anoyerwa padaro rakajairwa. Izvi zvakakosha zvikuru pakuisa munzvimbo dzinonzwa ruzha senge nzvimbo dzekugara kana zvipatara.

Mhedziso

Zita retransformer harisi kungori chirairo chiri nyore—igwaro rehunyanzvi rakazara rinotsanangura kugona kwechinhu chacho uye zvipingamupinyi. Kune nyanzvi dzekutenga, kunzwisisa maverengero nekududzira ruzivo urwu kunoita kuti pave nechokwadi chekuti zvinhu zvacho zvakatsanangurwa nemazvo, kudzivirira zvikanganiso pakushanda, uye kunogonesa kusarudza neruzivo nezvesarudzo uye mashandisirwo azvo.
