Iimpawu zeMveliso kunye noMgaqo

I-LCWD-35 i-transformer yangoku i-compact, incinci ngobukhulu kunye nokukhanya kobunzima.Isiqingatha esingasentla sisisiseko somoya, isiqingatha esisezantsi sisesibini ukujika, i-bushing igxininiswe kwisiseko, umphezulu we-bushing uxhotyiswe ngomgcini weoyile, i-oyile ephambili iphuma kumacala omabini eludongeni lwekhabhinethi, kunye ne-terminal yokuqala ephawulwe i-P1 I-sleeve encinci ye-porcelain isetyenziselwa ukufaka udonga lwekhabhinethi, kwaye isiphelo se-P2 sidibaniswe ngokuthe ngqo kudonga lwekhabhinethi.Umphambili wesigcini se-oyile uxhotyiswe ngeegeji ze-oyile ezibonisa amaqondo obushushu ahlukeneyo.

Umgaqo:
Kwimizila yokuvelisa amandla, i-substation, ukuhanjiswa, ukuhanjiswa kunye nokusetyenziswa, okwangoku kuyahluka kakhulu, ukusuka kwii-amperes ezimbalwa ukuya kumashumi amawaka e-ampere.Ukuze kuququzelelwe umlinganiselo, ukhuseleko kunye nolawulo, kufuneka uguqulwe ube ngumbane ofanayo.Ukongeza, i-voltage kumgca iphezulu kakhulu, njengokulinganisa ngokuthe ngqo, okuyingozi kakhulu.I-transformer yangoku idlala indima yokuguqulwa kwangoku kunye nokuhlukaniswa kombane.
Kwii-ammeters zohlobo lwe-pointer, ininzi yemigangatho yesibini ye-transformers yangoku ikwinqanaba le-ampere (njenge-5A, njl.).Kwizixhobo zedijithali, umqondiso wesampuli ngokubanzi kwinqanaba le-milliamp (0-5V, 4-20mA, njl.).Umbane wesibini we-miniature current transformer yi-milliampere, eyona nto isebenzayo njengebhulorho phakathi kwe-transformer enkulu kunye nesampuli.
I-miniature transformers yangoku ikwabizwa ngokuba yi "instrument current transformers".("Isixhobo sangoku isiguquli" sinentsingiselo yokuba sisiguquli sangoku esichanekileyo esisetyenziswa kwilebhu, esetyenziswa ngokubanzi ukwandisa uluhlu lwesixhobo.)
Ngokufana ne-transformer, i-transformer yangoku iphinda isebenze ngokomgaqo we-electromagnetic induction.I-transformer iguqula i-voltage kunye ne-transformer yangoku iguqula okwangoku.I-winding ye-transformer yangoku edityaniswe kumbane olinganisiweyo (inani lokujika yi-N1) libizwa ngokuba yi-primary winding (okanye i-primary winding, i-primary winding);ujiko oluqhagamshelwe kwisixhobo sokulinganisa (inani lokujika yi-N2) libizwa ngokuba lujiko lwesibini (okanye ukujija okwesibini).ukujija, ukujija okwesibini).
Umlinganiselo wangoku we-primary winding current i-I1 ukuya kwi-second winding i-I2 ye-transformer yangoku ibizwa ngokuba ngumlinganiselo wangoku we-K. Umlinganiselo wangoku we-transformer yangoku xa usebenza phantsi komlinganiselo olinganisiweyo ubizwa ngokuba ngumlinganiselo olinganisiweyo we-transformer yangoku. , echazwe nguKn.
Kn=I1n/I2n
Umsebenzi we-transformer yangoku (CT ngokufutshane) kukuguqula i-primary current kunye nexabiso elikhulu kwi-second current enexabiso elincinci ngomlinganiselo othile wokuguqulwa, osetyenziselwa ukukhusela, ukulinganisa kunye nezinye iinjongo.Ngokomzekelo, i-transformer yangoku enomlinganiselo we-400/5 inokuguqula i-current ye-400A ibe yi-5A yangoku.

UkuPhathwa kweNgxaki yeTransformer kunye nesicwangciso somyalelo

Ukuphathwa kweengxaki ezinxulumene neTransformer:
Iintsilelo zangoku ze-transformer zihlala zihamba kunye nezandi kunye nezinye iziganeko.Xa isiphaluka sesibini sivulwa ngequbuliso, kuveliswa amandla aphezulu kwikhoyili yesibini, kwaye ixabiso layo lencopho linokufikelela ngaphezu kwamawaka aliqela evolthi, nto leyo ebeka emngciphekweni ubomi babasebenzi kunye nokhuseleko lwezixhobo kwisekethe yesibini, amandla ombane aphezulu anokubangela umlilo we-arc.Ngexesha elifanayo, ngenxa yokunyuka okubukhali kwe-magnetic flux kwintsimbi yentsimbi, ifikelela kwindawo ephezulu yokugcwalisa.Ilahleko engundoqo kunye nobushushu bunzulu, obunokuthi bonakalise i-rheological winding yesibini.Ngeli xesha, i-non-sinusoidal wave ibangelwa ukunyuka kwe-magnetic flux density, eyenza i-vibration ye-silicon steel sheet ingalingani ngokugqithisileyo, okukhokelela kwingxolo enkulu.
1. Ukuphathwa kwe-transformer yangoku kwisiphaluka esivulekileyo Ukuba iphoso enjalo iyenzeka, umthwalo kufuneka ugcinwe ungatshintshi, isixhobo sokukhusela esinokuthi singasebenzi kakuhle kufuneka sivaliwe, kwaye abasebenzi abachaphazelekayo kufuneka baziswe ukuba bawuphelise ngokukhawuleza.
2. Unyango lwe-transformer yangoku yokuqhawula isiphaluka sesibini (isiphaluka esivulekileyo) 1. Isiganeko esingaqhelekanga:
a.Ukubonakaliswa kwe-ammeter yehla ukuya kwi-zero, isalathisi semitha yamandla esebenzayo kunye nesebenzayo iyancipha okanye i-oscillates, kwaye i-watt-hour meter ijikeleza kancinci okanye iyeke.
b.Isilumkiso soqhawulo lwepleyiti yoqhagamshelo eyahlukileyo.
c.I-transformer yangoku yenza ingxolo engaqhelekanga okanye ivelise ukushisa, ukutshaya okanye ukukhutshwa kwii-terminals zesibini, iintlantsi, njl.
d.Isixhobo sokukhusela i-relay siyala ukwenza, okanye ukungasebenzi kakuhle (le nto ifumaneka kuphela xa i-breaker circuit breaker ngempazamo okanye isala ukuhamba kwaye ibangele uhambo lwe-leapfrog).
2. Ukuphatha ngaphandle:
a.Ngoko nangoko xela uphawu kwishedyuli ekulo.
b.Ngokwe-phenomenon, gweba ukuba i-transformer yangoku yesiphaluka sokulinganisa okanye isiphaluka sokukhusela sivulekile.Ukuvalwa kokhuseleko olunokubangela ukusebenza ngempazamo kufuneka kuqwalaselwe phambi kokulahlwa.
c.Xa uhlola isiphaluka sesibini se-transformer yangoku, kufuneka ume kwi-insulating pad, ubeke ingqalelo kukhuseleko lomntu, kwaye usebenzise izixhobo zokukhusela ezifanelekileyo.
d.Xa isiphaluka sesibini se-transformer yangoku sivulekele ukubangela umlilo, amandla kufuneka anqunywe kuqala, kwaye ke umlilo kufuneka ucinywe ngendwangu eyomileyo ye-asbestos okanye ukucima umlilo owomileyo.
3. Impazamo yomzimba we-transformer yangoku Xa impazamo ye-transformer yangoku inenye yezi meko zilandelayo, kufuneka imiswe ngokukhawuleza:
a.Kukho isandi esingaqhelekanga kunye nokutshisa okugqithisileyo ngaphakathi, okukhatshwa ngumsi kunye nevumba elivuthayo.b.Ukuvuza okukhulu kweoli, i-porcelain eyonakeleyo okanye i-dicharge phenomenon.
c.Isitofu somlilo okanye i-glue flow flow phenomenon.
d.Ukwandiswa kwesandisi sesinyithi kudlula kakhulu ixabiso elichaziweyo kwiqondo lokushisa eliphakathi.

Isicwangciso sokuodola:
1. Ukubonelela ngedayagram yesikimu se-wiring, isicelo kunye nomzobo wenkqubo, i-voltage elinganisiweyo, i-current rated, njl.
2. Iimfuno zolawulo, umlinganiselo kunye nokukhusela imisebenzi kunye nezinye izixhobo zokutshixa kunye nezixhobo ezizenzekelayo.
3. Xa i-transformer isetyenziswe kwiimeko ezikhethekileyo zokusingqongileyo, kufuneka ichazwe ngokucacileyo xa iyala.
4. Xa ezinye okanye ii-accessories ezininzi zifuneka, uhlobo kunye nobungakanani kufuneka bucetywe.
