1. I-transformer iguqula kanjani i-voltage?
I-transformer yenziwe ngokususelwa ku-electromagnetic induction. Iqukethe umgogodla wensimbi owenziwe ngamashidi ensimbi ye-silicon (noma amashidi ensimbi ye-silicon) kanye namasethi amabili wamakhoyili alimele kumongo wensimbi. I-iron core namakhoyili avaleleke komunye nomunye futhi awaxhumeki ugesi.
Kuye kwaqinisekiswa ngokwethiyori ukuthi isilinganiso se-voltage phakathi kwekhoyili eyinhloko kanye nekhoyili yesibili ye-transformer ihlobene nenani lokuphenduka kwekhoyili eyinhloko kanye nekhoyili yesibili, engavezwa ngefomula elandelayo: ikhoyili eyinhloko. i-voltage/i-coil voltage yesibili = ijika ikhoyili yokuqala/ijika ikhoyili yesibili. Lapho amajika amaningi, i-voltage ikhuphuka. Ngakho-ke, kungabonakala ukuthi uma ikhoyili yesibili ingaphansi kwekhoyili yokuqala, i-transformer yesinyathelo esisuka phansi. Ngokuphambene nalokho, iyi-transformer ekhuphukayo.
2. Yibuphi ubuhlobo bamanje phakathi kwekhoyili yokuqala kanye nekhoyili yesibili ye-transformer?
Lapho i-transformer isebenza nomthwalo, ukuguqulwa kwekhoyili yesibili yamanje kuzodala inguquko ehambisanayo ku-primary coil current. Ngokusho komgomo webhalansi yamandla kazibuthe, ilingana ngokuphambene namanje wamakhoyili ayisisekelo nawesibili. Eyamanje eseceleni enamajika amaningi incane, kanti eyamanje eseceleni enamajika ambalwa inkulu.
Ingavezwa ngendlela elandelayo: ikhoyili yokuqala yamanje/ikhoyili yesibili yamanje = iyajika ikhoyili yesibili/ijika ikhoyili yokuqala.
3. Ungaqinisekisa kanjani ukuthi i-transformer ine-voltage elinganiselwe?
I-voltage ephakeme kakhulu noma ephansi kakhulu izothinta ukusebenza okuvamile kanye nempilo yesevisi ye-transformer, ngakho-ke ukulawulwa kwamandla kagesi kuyadingeka.
Indlela yokulawula amandla kagesi iwukuholela ngaphandle ompompi abambalwa kukhoyili yokuqala bese ubaxhuma emshinini wokushintsha umpompi. I-tap change ishintsha inani lokuphenduka kwekhoyili ngokuzungezisa abathintwayo. Inqobo nje uma isikhundla sokushintsha kompompi siphendukile, inani elidingekayo le-voltage elilinganiselwe lingatholwa. Kumele kuqashelwe ukuthi ukulawulwa kwe-voltage ngokuvamile kufanele kwenziwe ngemuva kokuthi umthwalo oxhunywe ku-transformer unqanyuliwe.
4. Yiziphi ukulahlekelwa kwe-transformer ngesikhathi sokusebenza? Indlela yokunciphisa ukulahlekelwa?
Ukulahlekelwa ekusebenzeni kwe-transformer kufaka izingxenye ezimbili:
(1) Kubangelwa umnyombo wensimbi. Lapho ikhoyili inikwa amandla, imigqa yamandla kazibuthe iyashintshana, okubangela ukulahleka kwe-eddy current kanye ne-hysteresis kumongo wensimbi. Lokhu kulahlekelwa kubizwa ngokuhlanganyela ngokuthi ukulahlekelwa yinsimbi.
(2) Kubangelwa ukumelana kwekhoyili ngokwayo. Uma okwamanje idlula amakhoyili ayisisekelo kanye nesesibili se-transformer, ukulahlekelwa kwamandla kuzokwenziwa. Lokhu kulahlekelwa kubizwa ngokuthi ukulahlekelwa kwethusi.
Isamba sokulahlekelwa kwensimbi nokulahlekelwa kwethusi ukulahlekelwa kwe-transformer. Lokhu kulahlekelwa kuhlobene namandla e-transformer, amandla kagesi kanye nokusetshenziswa kwemishini. Ngakho-ke, lapho ukhetha i-transformer, umthamo wemishini kufanele uhambisane nokusetshenziswa kwangempela ngangokunokwenzeka ukuze kuthuthukiswe ukusetshenziswa kwemishini, futhi kufanele kuqashelwe ukuthi ungasebenzisi i-transformer ngaphansi komthwalo omncane.
5. Iyini i-nameplate ye-transformer? Ithini idatha yobuchwepheshe eyinhloko ku-nameplate?
I-nameplate ye-transformer ibonisa ukusebenza, ukucaciswa kobuchwepheshe kanye nezimo zokusetshenziswa kwe-transformer ukuhlangabezana nezidingo zokukhetha komsebenzisi. Idatha eyinhloko yezobuchwepheshe okufanele inakwe ngesikhathi sokukhetha yilezi:
(1) I-kilovolt-ampere yomthamo olinganiselwe. Okungukuthi, umthamo wokukhipha we-transformer ngaphansi kwezimo ezilinganiselwe. Isibonelo, umthamo olinganiselwe we-transformer yesigaba esisodwa = umugqa we-U× I line; umthamo we-transformer yezigaba ezintathu = Umugqa× Ngilayini.
(2) I-voltage elinganiselwe ngama-volts. Khombisa i-terminal voltage yekhoyili eyinhloko kanye ne-terminal voltage yekhoyili yesibili (uma ingaxhumekile emlayishweni) ngokulandelanayo. Qaphela ukuthi i-voltage yokugcina ye-transformer yezigaba ezintathu ibhekisela enani lomugqa we-voltage U.
(3) Umsinga olinganiselwe ngama-ampere. Kubhekisela enanini lamanje le-line Ikhoyili ikhoyili yokuqala kanye nekhoyili yesibili okuvunyelwe ukudlula kuyo isikhathi eside ngaphansi kwezimo zomthamo olinganisiwe kanye nokukhuphuka kwezinga lokushisa okuvumelekile.
(4) Isilinganiso samandla kagesi. Ibhekisela esilinganisweni sevoltheji elinganiselwe yekhoyili eyinhloko kuvoltheji elinganiselwe yekhoyili yesibili.
(5) Indlela yokufaka izintambo. I-single-phase transformer inesethi eyodwa kuphela yamakhoyili kagesi aphezulu naphansi futhi isetshenziselwa ukusetshenziswa kwesigaba esisodwa kuphela. I-transformer enezigaba ezintathu ine-Y/△uhlobo. Ngaphandle kwedatha yezobuchwepheshe engenhla, kukhona futhi imvamisa elinganiselwe, inombolo yezigaba, ukuphakama kwezinga lokushisa, iphesenti le-impedance ye-transformer, njll.
6. Yiziphi izivivinyo okufanele zenziwe ku-transformer ngesikhathi sokusebenza?
Ukuze kuqinisekiswe ukusebenza okujwayelekile kwe-transformer, lezi zivivinyo ezilandelayo kufanele zenziwe njalo:
(1) Ukuhlolwa kwezinga lokushisa. Izinga lokushisa libaluleke kakhulu ukunquma ukuthi i-transformer isebenza ngokujwayelekile yini. Imithethonqubo ibeka ukuthi izinga lokushisa eliphezulu likawoyela akumele lidlule ku-85C (okungukuthi, ukukhuphuka kwezinga lokushisa ngu-55C). Ngokuvamile, ama-transformer afakwe imishini ekhethekile yokulinganisa izinga lokushisa.
(2) Isilinganiso somthwalo. Ukuze kuthuthukiswe izinga lokusetshenziswa kwe-transformer futhi kuncishiswe ukulahlekelwa kwamandla kagesi, amandla okunikezwa kwamandla i-transformer engawathwala ngempela kufanele alinganiswe ngesikhathi sokusebenza kwe-transformer. Umsebenzi wokulinganisa uvame ukwenziwa ngesikhathi esiphezulu sokusetshenziswa kukagesi enkathini ngayinye, futhi ulinganiswa ngokuqondile ne-clamp ammeter. Inani lamanje kufanele libe ngu-70-80% wesilinganiso samanje se-transformer. Uma idlula lobu bubanzi, isho ukugcwala ngokweqile futhi kufanele ilungiswe ngokushesha.
(3)Isilinganiso samandla kagesi. Imithethonqubo idinga ukuthi ububanzi bokuhluka kwamandla kagesi kufanele bube ngaphakathi±I-5% ye-voltage elinganiselwe. Uma idlula lobu bubanzi, umpompi kufanele usetshenziselwe ukulungisa i-voltage ebangeni elishiwo. Ngokuvamile, i-voltmeter isetshenziselwa ukukala i-coil terminal voltage kanye ne-terminal voltage yomsebenzisi wokugcina ngokulandelanayo.
