Kodwa i-xiaobian kulesi siqephu ingakutshela ukuthi, uma ukhetha uhlobo lwe-Q olunesibonisi esivaliwe esishajiwe, ungavimbeli i-node ekubonisweni okushajiwe iye emgqeni we-N, uma kungumugqa wesigaba wesibonisi esishajiwe uzokhanya, uma kungumugqa we-N wesibonisi esishajiwe awukhanyanga (okuhlangenwe nakho komuntu siqu)

Okwesibili, Ukulinganisa isekethe ye-transformer yamanje neye-voltage

I-Transformer iyi-transformer ekhethekile engashintsha i-voltage ephezulu ibe yi-voltage ephansi noma i-high current ibe yi-small current. Isetshenziswa kakhulu njengethuluzi lokulinganisa kanye nedivayisi yokuvikela i-relay.
Ukusebenza nokugcinwa kwe-transformer kuthinta ngqo ukunemba kokulinganisa ohlelweni lwamandla, ukuthembeka kokusebenza kwedivayisi yokuvikela kanye nokuphepha kwegridi yamandla, imishini kanye nomzimba womuntu.
I. Amaphutha avamile kanye nokwelashwa:

1. Ukuvalwa okuphuthumayo kwe-voltage transformer (i-current transformer) kufanele kwenzeke ngaphansi kwezimo ezilandelayo
(1) umkhuhlane omkhulu, intuthu, uwoyela.
(2) I-fuse eseceleni ene-voltage ephezulu ye-voltage transformer ihlanganiswa kabili ilandelana.
(3) Ukuqhekeka kwegobolondo, ukuvuza okukhulu kwamafutha.
(4) Umsindo wokuphuma kwangaphakathi noma umsindo ongajwayelekile.
(5) Imishini iyasha.

Indlela yokuphatha lapho i-voltage transformer ibhema noma ivutha: uma i-fuse ohlangothini oluyinhloko ingakaze ihlanganiswe ngaphambi kokuba kukhishwe intuthu, futhi i-fuse ohlangothini lwesibili ihlanganiswe izikhathi eziningi, futhi intuthu ingeyona embi kakhulu futhi ayinawo umonakalo wokushisa, futhi i-fuse ohlangothini oluyinhloko ayihlanganisiwe lapho kukhishwa intuthu, intuthu kufanele ihlulelwe ngokuthi ibangelwa ukujikeleza okufushane phakathi kwezigaba zokujika kwesibili (ukujika).
Ngaphambi komusi wesibili ogoqayo ngaphandle kokuthinta umonakalo wokufakwa kokushisa okuyinhloko, phuma ngokushesha kudivayisi yokuvikela efanele kanye ne-othomathikhi, susa i-fuse eseceleni yesibili, donsa inkinobho yokuhlukanisa yokugxila okuyinhloko, misa i-voltage transformer.
Ukuze kube nomshini wokuguqula i-voltage ogcwele uwoyela, uma kunentuthu eningi, futhi kunephunga elinamandla, umsindo ongajwayelekile, ukuze umshini wokuguqula i-voltage ujikeleze ngaphakathi ngamagobolondo noma umthofu phakathi kwegobolondo kanye nokukhishwa kwenhlansi, ukubhema ukuxubana kwe-fuse kohlangothi lokugcina lwe-2 ~ 3 okungaphansi, kufanele kwahlulelwe njengomonakalo wokufakelwa kwe-bilateral kanye nokubhema, ngakho-ke umshini wokuguqula i-voltage yebhasi, indlela yokuma kwebhasi usebenzisa i-voltage transformer,
Ngalesi sikhathi, i-voltage transformer ayikwazi ukumiswa ngokudonsa inkinobho yokunqamula, ngoba inkinobho yokunqamula ayinalo ikhono lokucisha i-arc. Uma inkinobho yokunqamula isetshenziselwa ukusika iphutha, ibhasi lingase linqanyulwe, okuholela ekulimaleni kwemishini noma engozini yomuntu siqu.
Uma i-voltage transformer isha, ugesi kufanele unqanyulwe ngokushesha, i-voltage transformer enephutha kufanele ihlukaniswe, bese kusetshenziselwa isicisha-mlilo esomile noma isihlabathi ukucima umlilo.

2. Isekethe yesibili ye-voltage transformer inqanyuliwe
Impendulo ye-Fenomenon:
(1) I-voltage yesigaba sesithathu ayilingani, i-voltage yesigaba sephutha iboniswa njengo-zero, kanti imitha yehora le-watt iboniswa njengongavamile
(2) Isibonakaliso esihambisanayo semitha yamandla esebenzayo kanye nemitha yamandla esebenzayo sincishisiwe noma singu-zero
(3) Isignali ethi “ukunqanyulwa kwe-voltage loop” ithunyelwa

Izindlela zokwelapha:
(1) sebenzisa i-multimeter ukukala ingxenye engenhla ye-core yesibili yesigaba ezimbili, uma isibonisi singama-V 100, bese ukala ingxenye engezansi yesibonisi kungekho 100V, khona-ke i-core yesibili iyasha, shintsha i-core yesibili.
Sebenzisa i-multimeter ukukala ingxenye engenhla ye-secondary melt core bese uthola ukuthi ayikho i-voltage engu-100V engaba yi-primary melt core eshile. Ngemva kokwehluleka kwamandla, kala ukuvala kwe-primary melt core ukuze ubone ukuthi ngabe iyi-primary melt core eshile.
(2) Hlola isekethe yesibili engavamile ye-voltage transformer ukuthi ayikhululekile, isekethe esifushane, umugqa ophukile nezinye izimo.

Okwesithathu, iluphu yokulawula

(1) Iluphu yokugcina amandla
Inkinga: Ama-motor awagcini amandla
Indlela yokucubungula: njengoba kuboniswe esithombeni, iluphu yokugcina amandla idlula endaweni elinganiselwe yokuxhumana okusizayo i-S8.1, inkinobho yokugcina amandla, injini.
Okokuqala hlola ukuthi izintambo azikhululekile. Uma zingakhululekile, hlola ukuthi inkinobho yokugcina amandla ilungile yini. Jikelezisa inkinobho uye esimweni esixhunyiwe, bese usebenzisa i-multimeter ukukala indawo yokuvula/yokuvala ukuze ubone ukuthi iphuzu liba iphuzu elivaliwe yini.
Uma isitoreji samandla kanye nezinkinobho zomkhawulo wokugcina amandla zisesimweni esihle, ngaphandle kwesimo sokugcina amandla i-S8.1 njengesimo esivame ukuvalwa, njengokuhlola ama-motor amaningana akukwazi kule nkinga, njengokuthi isekethe ingumshini oqondile (i-dc), hlola ukuthi uxhumano luhle yini, i-motor i-negative, uma ithatha i-lead ekubuyiseleni kwe-motor, uhlangothi lwesibili olukhanyayo lwe-core encibilikisiwe luyashiswa,
Uma umgogodla oncibilikisiwe mkhulu, injini izoqala ukulayisha ngokweqile futhi ishe.

(2) isekethe yokuvala
Ngenxa ye-elekthronikhi emihlanu, ngakho-ke isekethe yokuvala ngokusebenzisa ukuxhumana okusizayo idlula, isikhundla esivamile sokuxhumana okusizayo singu-① ukuxhumana okusizayo komnyango ophansi (kuphela egumbini lekhebula umnyango uvaliwe ngaphansi kwesimo sokuxhumana okusizayo okuvulekile kweluphu kungaba isimo esivamile sokuvala)
Ukuthintana okusizayo kokumisa umhlabathi (kuphela uma ummese wokumisa umhlabathi usesimeni esihlukile, ukuthintana okusizayo okuvame ukuvuleka kweluphu kungaba yisimo esivalekile)
(3) Ukuxhumanisa iswishi yokuxhumana eyisizayo (ngokuvamile ukuxhumana okusizayo okuvulekile kweluphu kungashintsha kube sesimweni esivamile sokuvalwa kuphela uma iswishi yokuxhuma isisesimweni sokuvalwa)
Indawo yokugcina amandla ukuxhumana okusizayo (ngokuvamile ukuxhumana okuvulekile kwesekethe kungashintsha kube isimo esivalekile kuphela uma injini isesimweni sokugcina amandla)

Ngakho-ke, cindezela inkinobho yokuvala i-SB1 kumdwebo, i-relay KA1 yokuqala izovalwa ngogesi, bese kuthi ukuxhumana okuvame ukuvuleka kwesekethe yokuvala i-KA1 kushintshe kube yisimo esivame ukuvalwa. Uma kuqinisekiswa ukuthi umnyango ongezansi uvaliwe, inkinobho yokuhlukanisa isesimweni sokuvala, inkinobho yokusekela isisekelo isesimweni sokuvula, futhi injini igcinwe amandla.
Ngalesi sikhathi, ikhoyili yokuvala isebenza ngogesi, futhi indlela yokuvala iswishi iyathintwa ukuze kuvalwe iswishi.
Ngakho-ke, uma singakwazi ukuvala isango, okokuqala, kufanele sahlulele zonke izimo zokuxhumana ezisizayo (okungukuthi, isimo sokushintsha komhlaba, isimo sokushintsha sokuhlukanisa, isimo sokugcina amandla enjini, isimo sokuvala umnyango ophansi) kusukela ezikhungweni zehadiwe kuya esimweni sangemuva ukuxazulula inkinga, okuzothola umphumela ophindwe kabili ngesigamu somzamo.

(3) isekethe yamabhuleki
Njengoba kungabonakala kumdwebo we-schematic, isekethe ilula kakhulu, udinga nje ukwahlulela i-break relay, i-break coil, inkinobho ye-break
