01 I-Inrush yamanje
Uma i-transformer iqala ukunikezwa amandla, kwenzeka into ebizwa ngokuthi i-magnetizing inrush. Nakuba ama-inrush currents ngokuvamile engaphazamisi njenge-fault currents, isikhathi sama-magnetizing inrush currents silandelana ngemizuzwana (uma kuqhathaniswa nezikhathi ezine-fault currents).

Isingeniso
i-transformer
Idivayisi eshintsha i-voltage, i-current, noma isigaba ngokuhlanganisa isekethe yamagnetic
Kungani ufunda ama-Transformers?
Ama-Transformer aziwa nangokuthi ama-motor e-AC amile

Le vidiyo ikubonise ukuthi i-power transformer eyinhloko ibukeka kanjani.

I-transformer iyithuluzi elingaguquki elisebenza njalo, elithembekile uma lisebenza futhi linamathuba amancane okwehluleka. Kodwa-ke, njengoba iningi lama-transformer lifakwe ngaphandle, futhi lithintwa umthwalo ngesikhathi sokusebenza kanye nephutha le-short-circuit yesistimu yamandla, amaphutha ahlukahlukene kanye nezimo ezingavamile zenzeka ngokungenakugwenywa ngesikhathi sokusebenza.

I-grounding transformer ibizwa ngokuthi i-grounding transformer ngamafuphi. Ngokusho kwe-filling medium, i-grounding transformer ingahlukaniswa ngohlobo lwamafutha nohlobo olomile; Ngokusho kwenani lezigaba, i-grounding transformer ingahlukaniswa ibe yi-grounding transformer yesigaba esithathu kanye ne-grounding transformer yesigaba esisodwa. Umsebenzi we-grounding transformer ukuhlinzeka ngephuzu elingathathi hlangothi lokwenziwa lesistimu elinephuzu elingathathi hlangothi elingaguquki, elilungele ukusetshenziswa kwe-arc suppression coil noma imodi encane yokuguquguqula ukumelana, ukuze kuncishiswe amandla kagesi emhlabathini uma kwenzeka iphutha le-grounding short circuit kunethiwekhi yokusabalalisa futhi kuthuthukiswe ukuthembeka kokunikezwa kwamandla ohlelweni lokusabalalisa.

Ukuhlaziywa kokusebenza okungajwayelekile kwama-transformer
Umsindo we-transformer awujwayelekile


Lapho nje i-transformer isixhunywe kugesi, kuzoba nomsindo ovunguzayo, obangelwa kakhulu umphumela we-magnetic flux enamandla aphezulu. Ngesikhathi sokusebenza okuvamile, umsindo we-transformer uyalingana. Uma kuneminye imisindo, kufanele uthole imbangela ngokucophelela bese ubhekana nayo.

(1) Umsindo we-transformer awujwayelekile
Lapho nje i-transformer isixhunywe kugesi, kuzoba nomsindo ovunguzayo, obangelwa kakhulu umphumela we-magnetic flux enamandla aphezulu. Ngesikhathi sokusebenza okuvamile, umsindo we-transformer uyalingana. Uma kuneminye imisindo, kufanele uthole imbangela ngokucophelela bese ubhekana nayo.

Ukusebenza okuhambisanayo kwama-transformer kusho ukuthi ukugoqa okuyinhloko kwama-transformer amabili noma ngaphezulu kuxhunywe ngokuhambisana kubha yebhasi ye-voltage efanayo, kanti ukugoqa kwesibili kuxhunywe ngokuhambisana kubha yebhasi yelinye i-voltage.






Incazelo yalo iwukuthi: lapho i-transformer eyodwa ihluleka, amanye ama-transformer asebenza ngokuhambisana angaqhubeka nokusebenza ukuqinisekisa ukusetshenziswa kwamandla kwabasebenzisi ababalulekile; noma lapho i-transformer idinga ukulungiswa, i-transformer elindile ingaxhunywa ngokuhambisana, bese i-transformer ezolungiswa ivuliwe futhi ilungiswe. , okungagcini nje ngokuqinisekisa ukulungiswa okuhleliwe kwe-transformer, kodwa futhi nokuqinisekisa ukuthi ukunikezwa kwamandla akuphazanyiswa futhi kuthuthukise ukuthembeka kokunikezwa kwamandla.

Ukuvikelwa kwegesi kuyisivikelo esiyinhloko samaphutha angaphakathi e-transformer. Kungasebenza ngozwelo kumasekethe amafushane e-transformer aphakathi kokuphenduka kanye naphakathi kwezingqimba, amaphutha e-iron core, amaphutha e-bushing yangaphakathi, ukunqanyulwa kokugoba kwangaphakathi, ukonakala kokushisa kanye nokwehla kwezinga likawoyela. Uma kwenzeka iphutha ngaphakathi kwe-transformer ecwiliswe uwoyela, i-arc izobola izinto zokuvikela futhi ikhiqize inani elikhulu legesi, eligeleza lisuka ethangini likawoyela liye emcamelweni kawoyela, futhi ukuqina kwalo kuyahlukahluka ngokobukhulu bephutha, okubonisa ukugeleza komoya kanye nokugeleza kukawoyela. Ukuvikelwa kwesenzo kubizwa ngokuthi ukuvikelwa kwegesi, okubizwa nangokuthi ukuvikelwa kwegesi. Ngesikhathi sokusebenza kwe-transformer, ngenxa yamaphutha angaphakathi, ngezinye izikhathi asikwazi ukuhlonza nokuthatha izinyathelo ngesikhathi, okulula ukubangela ezinye izingozi. Ngemva kokuvikelwa kwe-relay yegesi, ukwenzeka kwezigameko ezifanayo kungagwenywa ngezinga elithile.

1. Iyini i-transformer?


Kusekhethi ye-AC, idivayisi ekhulisa noma enciphisa i-voltage ibizwa ngokuthi i-transformer. I-transformer ingaguqula noma yiliphi inani le-voltage libe yinani le-voltage esiyidingayo ngemvamisa efanayo ukuze ihlangabezane nezidingo zokudluliselwa kwamandla kagesi, ukusatshalaliswa kanye nokusetshenziswa kwawo.


Isibonelo, ugesi ovela esiteshini samandla unezinga eliphansi le-voltage, futhi i-voltage kumele ikhuliswe ngaphambi kokuba ithuthwe iye endaweni ekude yokusebenzisa ugesi. Indawo yokusebenzisa ugesi kumele yehliswe ibe sezingeni elifanele le-voltage ukuze ihlinzeke ngemishini yamandla kanye nogesi wansuku zonke. Imishini.

Umbuzo:
"Kukhona i-transformer yakudala engu-1000KVA enomthwalo okhona ongaba ngu-200KW. Uma kuzongezwa umthwalo omusha ongaba ngu-600KW, ingabe le transformer ingamelana nayo?"
