Ezimbini, Ukulinganisa isekethe ye-transformer yangoku kunye ne-voltage

I-Transformer yitransformer ekhethekileyo enokutshintsha i-voltage ephezulu ibe yi-voltage ephantsi okanye i-current ephezulu ibe yi-current encinci. Isetyenziswa kakhulu kwizixhobo zokulinganisa kunye nesixhobo sokukhusela i-relay.
Ukusebenza nokugcinwa kwe-transformer kuchaphazela ngokuthe ngqo ukuchaneka kokulinganisa kwinkqubo yamandla, ukuthembeka kokusebenza kwesixhobo sokukhusela kunye nokhuseleko lwegridi yamandla, izixhobo kunye nomzimba womntu.
I. Iimpazamo eziqhelekileyo kunye nonyango:

1. Ukuvalwa okungxamisekileyo kwe-voltage transformer (i-current transformer) kufuneka kwenzeke phantsi kwezi meko zilandelayo
(1) umkhuhlane omkhulu, umsi, ioyile.
(2) I-fuse esecaleni ye-voltage ephezulu ye-voltage transformer idityaniswe kabini ngokulandelelana.
(3) Ukuqhekeka kweqokobhe, ukuvuza okukhulu kweoyile.
(4) Isandi sokukhupha ngaphakathi okanye isandi esingaqhelekanga.
(5) Izixhobo ziyatsha.

Indlela yokuphatha xa i-voltage transformer itshaya okanye itsha: ukuba i-fuse kwicala eliphambili ayikaze idityaniswe ngaphambi kokuba umsi ukhutshwe, kwaye i-fuse kwicala lesibini idityaniswe amaxesha amaninzi, kwaye umsi awubi mkhulu kwaye awunampawu yomonakalo we-insulation, kwaye i-fuse kwicala eliphambili ayidityaniswe xa umsi ukhutshwa, umsi kufuneka ugwetywe njengobangelwa yi-short circuit phakathi kwezigaba ze-secondary winding (turns).
Ngaphambi kokuba umsi wesibini ojikelezayo ungachaphazeli umonakalo wokuqala wokufakelwa, phuma ngoko nangoko kwindawo efanelekileyo yokukhusela kunye nesixhobo esizenzekelayo, susa i-fuse esecaleni yesibini, tsala iswitshi yokwahlukanisa yokugxila ephambili, yeka i-transformer yombane.
Kwi-oyile egcwele uhlobo lwe-voltage transformer, ukuba kukho umsi omninzi, kwaye ivumba elinamandla, ingxolo engaqhelekanga, i-voltage transformer yangaphakathi eneegobolondo okanye i-lead phakathi kwegobolondo kunye nokukhupha i-spark, ukutshaya i-fuse ecaleni lokugqibela ukuxubana kwe-2 ~ 3 isenzeko esingaphantsi, kufuneka kugwetywe njengomonakalo wokugquma kunye nokutshaya, ngoko ke i-busbar voltage transformer, i-bus stop way stop esebenzisa i-voltage transformer,
Okwangoku, i-voltage transformer ayinakuze iyekiswe ngokutsala iswitshi yokuqhawula, kuba iswitshi yokuqhawula ayinakho ukucima i-arc. Ukuba iswitshi yokuqhawula isetyenziselwa ukusika impazamo, ibhasi isenokunqunyulwa, nto leyo enokubangela umonakalo kwizixhobo okanye ingozi yomntu.
Xa i-voltage transformer itsha, umbane kufuneka ucinywe ngoko nangoko, i-voltage transformer enengxaki kufuneka ihlulwe, kwaye kufuneka kusetyenziswe i-dry fire extinguisher okanye isanti ukucima umlilo.

2. Isekethe yesibini ye-voltage transformer ayisebenzi
Impendulo yeziganeko:
(1) I-voltage yesigaba sesithathu ayilingani, i-voltage yesigaba sempazamo iboniswa njengo-zero, kwaye imitha yeyure ye-watt iboniswa njengongaqhelekanga
(2) Isalathisi esihambelanayo semitha yamandla esebenzayo kunye nemitha yamandla esebenzayo incitshisiwe okanye i-zero
(3) Isignali ethi “ukuqhawuka kwe-voltage loop” ithunyelwa

Iindlela zonyango:
(1) sebenzisa i-multimeter ukulinganisa isiphelo esiphezulu sesiseko sesibini esinezigaba ezibini, ukuba isibonisi yi-100V, uze ulinganise isiphelo esisezantsi sesibonisi akukho 100V, uze ulinganise isiseko sesibini sitshiswe, buyisela isiseko sesibini.
Sebenzisa i-multimeter ukulinganisa isiphelo esingaphezulu se-secondary melt core uze ufumanise ukuba akukho voltage ye-100V enokuba yi-primary melt core etshisiweyo. Emva kokusilela kombane, linganisa i-on-off ye-primary melt core ukuze ubone ukuba ingaba yi-primary melt core etshisiweyo na.
(2) Jonga isekethe yesibini engaqhelekanga ye-voltage transformer ukuze ubone ukuba ayikhululekanga, ayisebenzi kakuhle, ayisebenzi kakuhle kunye nezinye izinto.

Isithathu, iluphu yoLawulo

(1) Iluphu yokugcina amandla
Ingxaki: Iimoto azigcini amandla
Indlela yokucubungula: njengoko kubonisiwe kumfanekiso, iluphu yokugcina amandla idlula kwindawo elinganiselweyo yoqhagamshelwano oluncedisayo lwe-S8.1, iqhosha lokugcina amandla, injini.
Okokuqala jonga ukuba intambo ayikhululekanga na. Ukuba ayikhululekanga, jonga ukuba iqhosha lokugcina amandla lilungile na. Jikelezisa iqhosha liye kwimeko eqhagamshelweyo, kwaye usebenzise i-multimeter ukulinganisa indawo yokuvula/yokucima ukuze ubone ukuba inqaku liba yinqaku elivaliweyo na.
Ukuba iiswitshi zokugcina amandla kunye nokugcina amandla azikwazi ukusebenza kakuhle, ngaphandle kwemeko yokugcina amandla i-S8.1 njengemeko evaliweyo, njengokuvavanya iimoto ezininzi akukwazi ukusebenza kule ngxaki, njengokuba isekethe ingumbane othe ngqo (dc), jonga ukuba unxibelelwano lulungile na, ukuba i-motor itshintsha, icala elikhanyayo lesibini lombindi onyibilikisiweyo liyatsha.
Ukuba umbindi otyhidiweyo mkhulu, injini iya kuqala ukugcwala kakhulu ize itshise.

(2) isekethe yokuvala
Ngenxa yezixhobo zombane ezintlanu, ngoko ke isekethe yokuvala ngokusebenzisa i-contact encedisayo ingaphezulu, indawo eqhelekileyo yoqhagamshelwano oluncedisayo yi-① uqhagamshelwano oluncedisayo olusezantsi (kuphela kwigumbi lekhebula, ucango luvaliwe phantsi kwemeko yoqhagamshelwano oluncedisayo oluvulekileyo lwe-loop lunokuba yimeko evaliweyo eqhelekileyo)
Uqhagamshelwano oluncedisayo lokumisa umhlaba (kuphela xa imela yokumisa umhlaba ikwimeko eyahlukileyo, uqhagamshelwano oluncedisayo oluqhelekileyo oluvulekileyo lweluphu lunokuba yimeko evaliweyo)
(3) Uqhagamshelwano oluncedisayo lokuqhawula unxibelelwano (uqhagamshelwano oluncedisayo oluvulekileyo lweluphu lunokutshintsha lube kwimeko evaliweyo kuphela xa iswitshi yokuqhawula unxibelelwano ivaliwe)
Indawo yokugcina amandla, unxibelelwano oluncedisayo (unxibelelwano oluvulekileyo lwesekethe lunokutshintsha lube kwimeko evaliweyo kuphela xa injini ikwimeko yokugcina amandla)

Ngoko ke, cofa iqhosha lokuvala elithi SB1 kumzobo, i-relay KA1 yokuqala iya kuvalwa ngombane, kwaye emva koko unxibelelwano oluqhelekileyo oluvulekileyo lwesekethe yokuvala i-KA1 luya kutshintsha lube kwimeko eqhelekileyo yokuvalwa. Ukuba kuqinisekisiwe ukuba ucango olusezantsi luvaliwe, iswitshi yokuzihlukanisa ikwimeko yokuvala, iswitshi yokumisa umhlaba ikwimeko yokuvula, kwaye injini igcinwe amandla.
Ngeli xesha, ikhoyili yokuvala isebenza ngombane, kwaye indlela yokuvala iswitshi iyachukunyiswa ukuze ivale iswitshi.
Ngoko ke, xa singakwazi ukuvala isango, okokuqala, kufuneka sigwebe zonke iimeko zoqhagamshelwano ezincedisayo (oko kukuthi, imeko yokutshintsha komhlaba, imeko yokutshintsha ukuhlukaniswa, imeko yokugcina amandla emoto, imeko yokuvala ucango olusezantsi) ukusuka kwizixhobo zehardware ukuya kwimeko yangasemva ukusombulula ingxaki, eya kufumana isiphumo esiphindwe kabini ngesiqingatha somzamo.
