Isixhumanisi esibuthakathaka ohlelweni lokuvikela i-relay yi-transformer ku-voltage yesistimu yamandla.Ku-loop ye-voltage, kulula ukungasebenzi kahle ngesikhathi sokusebenza.I-transformer ku-voltage idlala indima ebaluleke kakhulu ekusebenzeni okujwayelekile kwesistimu yamandla.Umsebenzi, nakuba kungekho amadivaysi amaningi kakhulu ohlelweni lwesifunda sesibili se-voltage transformer, futhi inqubo ye-wiring ayiyona inkimbinkimbi kakhulu, kuyohlale kukhona amaphutha anjalo kanye nezinye kule nqubo.Amaphutha avela kumjikelezo wesibili we-voltage transformer awakwazi ukushaywa indiva, futhi angase abangele ngisho nemiphumela emibi kakhulu, njengokungasebenzi kahle nokwenqaba kwedivayisi yokuvikela.Ngokwesimo esidlule, isekethe yesibili ye-voltage transformer isenqubweni Ukwehluleka kuboniswa ikakhulukazi kulezi zici ezilandelayo:
1. Indlela yokumisa iphuzu yesifunda sesibili se-voltage transformer ihlukile esimweni esivamile.Isifunda sesibili se-voltage transformer asibonisi isisekelo sesibili noma isisekelo samaphuzu amaningi.Isisekelo sesibili sibizwa nangokuthi isisekelo sesibili esibonakalayo.Isizathu esiyinhloko salokhu ngaphezu kwenkinga yegridi yokubeka phansi esiteshini, inkinga ebaluleke kakhulu isenqubo yokufaka izintambo.Ukubekwa phansi kwesibili kwenzwa ye-voltage kuzokhiqiza i-voltage ethile phakathi kwayo negridi yaphansi.Le voltage inqunywa izinga lokungalingani phakathi kwama-voltages kanye nokumelana okukhiqizwa ukuxhumana komunye nomunye, kanye ne-voltage ekhiqizwa ngokuthintana negridi yaphansi Ngesikhathi esifanayo, izophinde ibekwe phezulu phakathi kwe-voltage yedivayisi ngayinye yokuvikela, okuzobangela ushintsho oluthile lwenani le-amplitude ye-voltage yesigaba ngasinye kanye nokuguquguquka kwesigaba esihlobene ngokwezinga elithile, okuzobangela ukuthi i-impedance kanye nezingxenye eziqondisayo zingasebenzi kahle futhi zenqabe ukunyakaza..
2. I-voltage kanxantathu ovulekile we-voltage transformer ayijwayelekile ku-loop.I-voltage kanxantathu ovulekile we-voltage transformer izonqanyulwa ku-loop.Kunezizathu zemishini.Ukwenzeka kwesekethe emfishane ngesikhathi esifanayo kuhlobene kakhulu nemikhuba ethile yokusebenzisa yabasebenza ngogesi.Ukuze kuzuzwe inani elinqunyiwe le-voltage ye-zero-sequence, ngaphansi kokuvikelwa kwe-transformer nebhasi ye-electromagnetic, ukumelana nomkhawulo wamanje we-relay ku-voltage kufushane-circuited.Abanye abantu baze basebenzise i-relay esezingeni elincane uma kuqhathaniswa.Umphumela uba Izonciphisa kakhulu into yokuvimbela i-voltage ye-delta evulekile ku-loop.Kodwa-ke, uma kukhona iphutha eliphansi ngaphakathi kwesiteshi noma endaweni yokuphuma, i-voltage ye-zero yokulandelana izoba nkulu ngokuqhathaniswa, futhi ukuvinjelwa komthwalo weluphu kuzoba kuncane uma kuqhathaniswa.I-current izoba nkulu, futhi ikhoyili ye-relay yamanje izoshisa kakhulu, okuzokwenza ukuthi ukufakwa kwe-insulation kulimaze, bese kwenzeka isifunda esifushane.Uma isimo se-short-circuit sihlala isikhathi eside, sizokwenza ukuthi ikhoyili ishise.Akuvamile ukuthi i-voltage transformer iphule ikhoyili eshile.
3. Ukwehla kwamandla kagesi esibili ama-voltage transformer Ukulahleka kwe-voltage yesibili kuma-voltage transformer inkinga yakudala evame ukwenzeka ezinhlelweni zokuvikela amandla kagesi.Isizathu esiyinhloko sale nkinga ukuthi ukusebenza kwezinhlobo ezahlukene zemishini yokuphula akuphelele..Nokungapheleli kwenqubo ye-loop yesibili.
4. Sebenzisa izindlela zokuhlola ezifanele
4.1 Indlela yokuhlola ngokulandelana Le ndlela iwukusebenzisa izindlela zokuhlola nokususa iphutha ukuze kutholwe umsuka wephutha.Kwenziwa ngokulandelana kokuhlolwa kwangaphandle, ukuhlolwa kokufakwa ngaphakathi, ukuhlolwa kwenani elingaguquki, ukuhlolwa kokusebenza kokunikezwa kwamandla, ukuhlolwa kokusebenza kokuvikela, njll. Le ndlela isetshenziswa kakhulu ekuhlulekeni kokuvikelwa kwe-microcomputer.Kusezinhlelweni zokusingatha izingozi lapho kunenkinga ngokunyakaza noma ukucabanga.
4.2 Sebenzisa lonke isethi yendlela yokuhlola Injongo eyinhloko yale ndlela ukuhlola ukuthi ingabe ingqondo yesenzo nesikhathi sokwenza sedivayisi yokuvikela kujwayelekile, futhi ngokuvamile kungathatha isikhathi esifushane ukukhiqiza kabusha iphutha.Futhi uhlonze umsuka wenkinga, uma kukhona okungavamile, bese uhlanganisa ezinye izindlela zokuhlola.
4.3 Indlela yokuhlola ukulandelana okuhlehliswayo Uma irekhodi lesigameko lesihloli sokuvikela i-microcomputer kanye nesiqophayo samaphutha kagesi singakwazi ukuthola umsuka wengozi ngesikhathi esifushane, kufanele kuqashelwe umphumela wengozi.Bheka phambili kusuka ezingeni uye kwelinye kuze kutholakale imbangela eyinhloko.Le ndlela ivame ukusetshenziswa lapho isivikelo singasebenzi kahle.
4.4 Lusebenzise ngokugcwele ulwazi olunephutha olunikezwe umhloli wokuvikela i-microcomputer, bese ulandela izinyathelo ezifanele.
(1) Sebenzisa ngokugcwele irekhoda yephutha kanye nerekhodi lesikhathi.Irekhodi lomcimbi, imidwebo yerekhoda yephutha, nesignali yokubonisa ukukhanya kwedivayisi yesihloli sokuvikela ukudluliselwa kwekhompyutha kuyizisekelo ezibalulekile zokuphatha ingozi.Ukwenza izahlulelo ezifanele ezisekelwe olwazini oluwusizo kuyisihluthulelo sokuxazulula inkinga.
(2) Ngemuva kwezingozi ezithile zokuvikela ukudluliselwa, imbangela yokwehluleka ayikwazi ukutholakala ngokusho kwemiyalelo yesignali endaweni.Noma ayikho inkomba yesignali ngemva kohambo lwe-circuit breaker, futhi akunakwenzeka (ukuchaza) ingozi eyenziwe ngumuntu noma ingozi yemishini.Lesi simo ngokuvamile sibangelwa ukunaka okunganele kwabasebenzi, izinyathelo ezingenele, nezinye izizathu.Izingozi ezenziwe umuntu kufanele zibonakale ngokweqiniso ukuze kuhlaziywe futhi kugwenywe ukuchitha isikhathi.
