Ukusebenza Umfuziselo transformers - Izimo

Amandla - Sekuyisikhathi eside iyingxenye ebalulekile yempucuko. Ngaphandle-ke, zibone ngeso lengqondo impilo ingenzeki. Yingakho umbuzo ngokuqhubeka ugesi ukuze abathengi ofundiswa ngokuya sibi. Ukusebenza okucishe kufane nalokhu transformers - eyodwa yalezi zindlela. Nokho, uma kuphela isipele kusetshenziswa indlela, futhi yiziphi izimfuneko imishini?

Kungani kudingeka ukusebenza okucishe kufane nalokhu transformers?

Njengoba kushiwo ngenhla, umsebenzi ekuqaleni bavumelana iye okubangelwa isidingo siwethembe kakhudlwana ugesi. Nokho, kunezinye, kubaluleke, ikakhulukazi lapho ukusebenza okucishe kufane nalokhu transformers edingekayo. La maphuzu zibandakanya:

• ukwanda okusheshayo e umthwalo, okuyinto esikhathini esizayo esiseduze ziyoyidlula (noma idlula) esebenza ngamandla transformer;
• yokuntuleka isikhala (ukuphakama, ububanzi) abanakukwazi ukusungula transformer esisodwa esikhulu, kodwa ungafaka amabili amancane ukuwafaka parallel;
• Ngokwemvelo, zokuvikela zidlala indima ebalulekile, njengoba ematfuba ukwehluleka ngesikhathi esisodwa kokubili transformers sincane kakhulu, kodwa, ngakho ngaphezu kulo mcimbi, ukusebenza okucishe kufane nalokhu Transformers, ukusebenzisa ezinye izindlela eyisipele.

Ukubeka kokusebenza Transformers ezimbili

Ukuvula transformers umsebenzi parallel inikeza komsebenzi abamukelayo esibaluleke ngokukhethekile amandla kagesi, okusho ungaphazanyiswa ugesi. On asetshenziswa iningi ezincane, Transformers ezimbili noma ngaphezulu (Okuhlukile ukudluliswa mncane uhlobo substation). Ukusebenza parallel uvunyelwe, uma kokubili transformer neqoqo elithile izidingo, ezibizwa ngokuthi "izimo wokusebenza okucishe kufane nalokhu transformers":

• iqembu Windings kufanele lifane komunye nomunye;
• ukuguqulwa okungu kufanele ulingana nomunye, sibe ukuphambuka insubstantial ngaphakathi eyamukelekayo imikhawulo zifane;
• voltage izifunda okufutshane kufanele alingane nomunye, kuba ukuphambuka insubstantial ngaphakathi eyamukelekayo imikhawulo zifane;
• Transformers parallel okudingeka ukuba inikwa amandla yi kusukela kunethiwekhi eyodwa;
• amakhebuli yesibili adingekayo yokuxhuma transformer kuze kube seqophelweni kufanele kube nezici okungenani zilingana futhi ubude;
• isigaba shift phakathi voltages we Windings aphansi nezamabanga aphakeme kumelwe kube okufanayo.

Isidingo ukubala kwangaphambilini

Endabeni ka umonakalo ka omunye transformers emibili akusho ngaso sonke kungenzeka ukukhetha nse, okuyinto ngokugcwele ifaniswe izimo yokusebenza izindlela ezilimele futhi. Kulezi zimo, kukhethwa transformer lusekelwe ku izibalo eziyinkimbinkimbi kwangaphambilini ezibonisa ukuthi kokubili Windings we transformer uzolayishwa ngokulinganayo, futhi omunye wabo ngeke ukulayisha lingaphezu komthamo ngayinye transformer ngabanye.

Isekhethi voltage

Ukusebenza okucishe kufane nalokhu transformers kuyatholakala at amagugu kuqhathaniswa alinganayo voltage izifunda okufutshane ku Windings. Uma amanani ahlukene RS, ngaphambi kokushintsha nomsebenzi ngokuhlanganyela kuyadingeka ukuze ngaphambilini ukushintsha isilinganiso ushintsho we transformers nge inkinobho ekhethekile. Ngakho kungenzeka ukuba sifinyelele isinxephezelo ubhekane nokucindezeleka isabalaliswe okuyinto kuphakama ngenxa umehluko iDemo wesifunda voltages. Ezivukayo ngenxa lokungafani enjalo nokulingana imisinga ngeke overload transformer ngezinhlamvu ezincane iphutha voltage.

Yiqiniso, kumelwe acabangele umthamo umthwalo - noma ngokuhlukile lisebenze ngamunye, futhi ngesikhathi semicimbi ezifana ukusebenza okucishe kufane nalokhu amandla transformers. Nokho, ngezinye engenzi lutho, umahluko nhlobo nethonya amagugu voltage isekhethi, ngoba okungu ukuguqulwa kuthiwa equalized futhi babe ezifanayo. Ngaphansi umthwalo, voltage yesibili kuzohluka, ngoba ukungalingani kwamandla iconsi kungadala ukuvuza uhlawula imisinga i Windings, nomunye transformer uhlawula zamanje sihlanganiswe sizindza, kanti eyesibili sisuswe. Isilinganiso Kunconywa besikhundla enamandla kunazo zonke yokushukumisa aphansi kakhulu amandla transformer akumelwe ibe ezingaphezu kwezintathu komunye.

izimo Iyatholakala

ukusebenza Umfuziselo Transformers, ezintathu-emazombezombe, ezimbili emazombezombe kuzo zonke Windings. Kumele kukhunjulwe ukuthi zikagesi exhunywe parallel, umthwalo kwasakazwa Ingxenye ephambene ukuze isekhethi voltage ngokuqondile wakhona amandla ngamunye transformer ngabanye. Ukusebenza okucishe kufane nalokhu Transformers, uma amaqembu uxhumano emazombezombe zihlukile, kungenzeka nhlobo amaqembu aphambene. Uma ukufakwa akuyona enokuxhumana ke ngenxa shift igebe eliphakathi ezikhumulweni we Windings yesibili kukhona voltage elibangela i engamukeleki yokwanda zamanje.
