Yiziphi izimiso zobuchwepheshe zama-transformer ohlobo olomile? Yimiphi imisebenzi yawo?

1. Amapharamitha obuchwepheshe we-transformer yohlobo olomile

Ama-transformer ohlobo olomile asetshenziswa kabanzi ekukhanyeni kwendawo, ezakhiweni eziphakeme, ezikhumulweni zezindiza, emishinini nasemishinini ye-CNC yedokhi, njll. Kalula nje,

Ama-transformer ohlobo olomile abhekisela kuma-transformer anezinsika zensimbi kanye nama-windings angafakwanga uwoyela wokuvikela.

Imingcele yobuchwepheshe efanele yama-transformer ohlobo olomile ifaka:

A. Umthamo olinganisiwe (kVA): Umthamo ongalethwa ngesikhathi sokusebenza okuqhubekayo ku-voltage elinganisiwe kanye nomthamo wamanje olinganisiwe.

B. I-voltage elinganisiwe (kV): I-voltage yokusebenza engakwazi ukumelana ne-transformer ngesikhathi sokusebenza kwesikhathi eside.

Ukuze kuhlangatshezwane nezidingo zokushintsha kwamandla kagesi egridi, uhlangothi olune-voltage ephezulu lwe-transformer lunama-tap,

okungalungiswa ngokulungisa inani lokujika ekugoqeni kwe-voltage ephezulu ukuze kulawulwe i-voltage yokuphuma ohlangothini lwe-voltage ephansi.

C. Ugesi olinganisiwe (A): Ugesi olinganisiwe uvunyelwe ukudlula ku-transformer isikhathi eside ngaphansi komthamo olinganisiwe.

D. Ukulahlekelwa umthwalo (kW): Amandla asebenzayo adonswa lapho i-voltage elinganisiwe ngemvamisa elinganisiwe isetshenziswa ku-terminal eyodwa ejikelezayo kanye

ama-windings asele ayi-open circuit. Ahlobene nenqubo yokusebenza kanye nokukhiqiza kweshidi lensimbi le-silicon eliyinhloko,

kanye ne-voltage esetshenzisiwe.

E. Ugesi ongenamthwalo (%): Uma i-transformer ingaphansi kwe-voltage ekalwe futhi uhlangothi lwesibili lungenamthwalo, ugesi odlulayo

ukugoqa okuyinhloko ngokuvamile kuvezwa njengephesenti lamanje alinganisiwe.

F. Ukulahlekelwa umthwalo (kW): Fushanisa ukugoqa kwesibili kwe-transformer bese usebenzisa ugesi olinganiselwe ekugoqeni okuyinhloko ku-

indawo yokuthepha elinganisiwe. Lokhu amandla asetshenziswa yi-transformer.

G. I-voltage ye-Impedance (%): Yehlisa i-circuit yokugoqa kwesibili kwe-transformer bese ukhuphula kancane i-voltage ekugoqeni okuyinhloko.

Uma ugesi we-short-circuit we-secondary winding ulingana nenani elilinganiselwe, i-voltage esetshenziswa ohlangothini oluyinhloko iyi-impedance

I-voltage. Ngokuvamile ivezwa njengephesenti le-voltage elinganisiwe.

H. Inombolo yesigaba kanye nokuphindaphinda: Isigaba sesithathu simelelwa ngu-S, kanti isigaba esisodwa simelelwa ngu-D. Imvamisa f yesizwe saseShayina

ejwayelekile ingu-50Hz.Kukhona amazwe aphesheya ane-60Hz (njenge-United States). I. Ukwenyuka kwezinga lokushisa nokupholisa: Umehluko phakathi

izinga lokushisa le-transformer winding noma ungqimba lwamafutha olungaphezulu kanye nezinga lokushisa lendawo ezungezile libizwa ngokuthi izinga lokushisa

ukukhuphuka kwengqimba kawoyela egoqekayo noma engenhla. Inani elilinganiselwe lokukhuphuka kwezinga lokushisa kwe-transformer ecwiliswe ku-oyela lingu-65K, kanti

Ukuphakama kwezinga lokushisa kobuso bukawoyela kungu-55K. Kukhona nezindlela ezahlukahlukene zokupholisa: ukuzipholisa okucwiliswe uwoyela, ukupholisa umoya okuphoqelelwe, ukupholisa amanzi,

uhlobo lweshubhu, uhlobo lweshidi, njll.

J. Izinga lokuvikela: Kunezindinganiso zamazinga okuvikela. Izinga lokuvikela le-transformer ene-voltage ephezulu elinganisiwe engu-35 kV kanye nesilinganiso esilinganisiwe

i-voltage ephansi engu-10 kV imelelwa njenge-LI200AC85/LI75AC35, lapho i-LI200 ikhombisa ukuthi i-transformer ine-high-voltage lightning impulse

ukumelana ne-voltage engu-200 kV, i-voltage emelana ne-frequency yamandla engu-85 kV, kanye ne-voltage emelana ne-lightning impulse engu-75 kV ene-voltage ephansi,

kanye nemvamisa yamandla emelana ne-voltage engu-35 kV. Izinga lokuvikela lamanje lemikhiqizo ye-transformer ecwiliswe uwoyela ye-Aux High-Tech Co., Ltd.

yi-LI75AC35, okubonisa ukuthi i-transformer ine-voltage yokumelana nombani enamandla aphezulu angu-75 kV kanye ne-frequency yamandla yokumelana nombani.

i-voltage engu-35 kV. Ngenxa yokuthi i-voltage ephansi ingu-400 V, inganakwa.

K. Ilebula leqembu lokuxhuma: Ngokusho kobudlelwano besigaba phakathi kokugoba okuyinhloko nokwesibili kwe-transformer, i-transformer

ama-winding axhunywe ezinhlanganisweni ezahlukahlukene, ezibizwa ngokuthi iqembu lokuxhuma lama-winding. Ukuze kuhlukaniswe ukuxhumana okuhlukile

emaqenjini, ukubhalwa kwewashi kuvame ukusetshenziswa, okungukuthi, i-phasor ye-voltage yomugqa ohlangothini lwe-voltage ephezulu isetshenziswa njengesandla eside sewashi,

iqiniswe ku-12, kanti i-phasor ye-line voltage ohlangothini lwe-low-voltage isetshenziswa njengesandla esifushane sewashi. Inombolo yesandla esifushane ikhombisa

ilebula leqembu lokuxhumana. Isibonelo, i-Dyn11 ikhombisa ukuthi ukugoqa okuyinhloko kuxhunyiwe (unxantathu), kanti ukugoqa okwesibili kuxhunyiwe (inkanyezi).

ngephuzu eliphakathi nendawo, kanti inombolo yeqembu ingamaphuzu (11).

2. Izidingo zobuchwepheshe zama-transformer ohlobo olomile

(1) Umzimba we-transformer wohlobo olomile:

Ukugoqa okunamandla aphezulu kwenziwa ngocingo lwethusi kanti ukugoqa okunamandla aphansi kwenziwa nge-foil yethusi. Ikhoyili yenziwe

i-epoxy resin glass fiber engenisiwe ingena ku-vacuum egcwele, inokuqina okuqinile kanye namandla okusebenza, kanye nokumelana okuhle kwe-short-circuit. Ama-ampere-turns e-

amakhoyili ane-voltage ephezulu kanye ne-voltage ephansi kufanele alinganiswe. Ingxube ye-epoxy resin glass fiber ine-coefficient efanayo yokukhulisa ukushisa njenge-conductor yethusi,

ukuqinisekisa ukuthi ikhoyili ayiqhekeki. Isebenza kahle kakhulu ekushabalaliseni ukushisa. Ifakwe uhlelo lokulawula ukuboniswa kokushisa oluzenzakalelayo

ibonisa izinga lokushisa lokugoqa kwe-transformer kwezigaba ezintathu. Uma umkhawulo wokushisa usufinyelelwe, i-thermostat ingathumela isignali ngokuzenzakalelayo

ukulawula ukuqala nokuma kwefeni, ukuvikelwa kwe-alamu yokushisa okweqile kanye nesenzo, kanye nokunikeza oxhumana nabo ababili abangasebenzi ukuze bavule ngokuzenzakalelayo isiteshi esincane

ifeni yokukhipha ugesi.

Ingaphakathi lensimbi kanye nazo zonke izingxenye zensimbi eziveziwe kufanele ziphathwe ngokuvimbela ukugqwala. Ipuleti legama lenziwe ngensimbi engagqwali, kanye nedatha ebalulekile

Okuhlobene ne -transformer kumakwe epuletini legama ngokwezindinganiso zikazwelonke. Igobolondo elihlanganisiwe lihlanganiswe endaweni, futhi izinto zegobolondo zifakiwe

yenziwe ngepuleti lensimbi engagqwali. Ine-interface yokuxhumana engu-485, engadlulisela isimo sokusebenza se-transformer.

(2) I-transformer yohlobo olomile ingasebenza ngomthwalo ongu-100% ngaphansi kwesimo sokuthi ifeni ayisebenzi ngaphandle kokushisa ngokweqile; ivunyelwe ukusebenza nge

Ukulayisha ngokweqile okungu-50% ngaphansi kwesimo sokuthi ifeni isebenza kahle, ngaphandle kokushisa ngokweqile, ukwesabisa, noma ukukhubeka.

(3) Ukulahlekelwa yi-transformer yohlobo olomile ngaphandle komthwalo:

Ukulahlekelwa umthwalo kwenziwa ngokwezinga likazwelonke elinephutha elibi, hhayi iphutha elihle, futhi kumele kuhambisane nokusetshenziswa kwakamuva.

amazinga eShandong Electric Power Company.

(4) Inkomba yomsindo:

I-transformer engu-2000KVA ingaphansi kuka-52ab uma ifeni yokusebenza evamile ingasebenzi.

(5) Ibanga lokuhamba ngezinyawo:

Izinto eziphilayo ezingengaphansi kuka-20mmKV, i-porcelain engengaphansi kuka-18mm/KVo20, ukuphepha komoya okune-voltage ephezulu ohlangothini oluya emhlabathini kanye nokuphepha komoya osezingeni lesigaba kuya esigabeni

imvume (izingxenye ezibukhoma) 2125mmo.

(6) Ulayini ongenayo one-voltage ephezulu uyikhebula, elihlangabezana nezidingo zemigqa engenayo ephezulu noma engezansi; ulayini ophumayo one-voltage ephansi uyipayipi lebhasi, eli

umugqa ophumayo ophezulu.

(7) Ikhabhinethi kufanele ifakwe iminyango yokungena kanye namafasitela okuhlola ngaphambili nangemuva ukuze kube lula ukuhlolwa kwamalunga ezingxenyeni ezahlukene.

(8) Ifakwe idivayisi yokulinganisa izinga lokushisa kanye nebhokisi lokulawula izinga lokushisa; inkinobho encane ebhokisini lokulawula isebenzisa ukunemba komkhiqizi

Ukunikezwa kwamandla kagesi okungu-24V. Zonke izingxenye kufanele zisebenzise imikhiqizo yohlobo lokufakelwa okuqinisiwe eqinisekiswe yi-"Two Departments".

(9) I-terminal (10cm) yocingo lomhlabathi olulengayo kufanele ishiywe endaweni efanele, bese kuthi okunye kupendwe ngopende wombala wesigaba ohambisanayo.

(10) Ngaphansi kwezimo zokusebenza ezijwayelekile kanye nezimo zomthwalo, i-transformer inempilo yokusebenza yeminyaka engu-230.

(11) Okunye okuqukethwe okungashiwongo kuzosetshenziswa ngokwe-GB6450-86.
