Kungani kufanele kube nomkhawulo owodwa we-CT osekelwe phansi?

Ukuguqulwa kwesibili kwei-transformer yamanjekanye ne-voltage transformer kufanele ibekwe phansi ngesikhathi sokusebenza, ukuze kuvinjelwe i-voltage ephezulu ukuthi ingangeni ku-voltage ephansi nge-transformer ngokulandelana ngemva kokuba ukufakelwa kwe-transformer kuphukile, kulimaze ithuluzi kanye nabasebenzi bokusebenza. Ukufakwa phansi kwe-transformer endaweni yesibili ngeke kuthinte ukusebenza okuvamile kwemishini, kodwa futhi kuqinisekisa ukuphepha kwabasebenzi kanye nemishini.
Ukuqinisekisa ukuphepha, uhlangothi lwesibili lwe-CURRENT transformer kumele lubekwe phansi ukuze luvikele umzimba womuntu kanye nemishini lapho uhlangothi lwesibili lwe-current transformer lusengozini ephezulu yamandla kagesi.

I-transformer yamanjeisenzo

Enqubweni yokukhiqiza, siqapha isimo sokusebenza kwemishini ngayinye ohlelweni ukuqinisekisa ukusebenza okuphephile kwesistimu yamandla.
I-transformer yamanje ivame ukuguqula ugesi omkhulu wesekethe eyinhloko ibe ugesi omncane wesibili ohambisana ngqo nawo, bese ekugcineni ukhipha ugesi omncane wesibili uye ethuluzini lesibili, ukuvikelwa kokudluliselwa kanye nedivayisi ezenzakalelayo ukuze isetshenziswe.
Ngakho-ke, i-transformer yamanje ingumthombo wamanje we-ac wezingxenye zokulawula zikagesi, imithethonqubo, ukulinganisa kanye nokuvikela, kanye nesikhungo sokuxhumana phakathi kwesekethe yesibili kanye nesekethe eyinhloko.

Kungani uhlangothi lwesibili lwe-CT lungenakuvulwa?
Ngenxa yokuthi isekethe yesibili ye-CT ivuliwe, ugesi wesibili uzonyamalala, kanti ne-demagnetization nayo izonyamalala, okuholela ekuxineni okuphezulu kwamagnetic enkabeni.
Futhi ngenxa yokuthi inani lokujika kokujikeleza ohlangothini lwesibili likhulu kakhulu kunenani lokujika kokujikeleza ohlangothini oluyinhloko, ngakho-ke uma uhlangothi lwesibili seluvuliwe, kuzoba ne-voltage ephezulu enhle, ngezinye izikhathi kuze kufike ezinkulungwaneni zama-volt, ngakho-ke akugcini nje ngokubeka engcupheni imishini eseceleni yesibili, kodwa futhi kubeka engcupheni ukuphepha komuntu siqu.

Kungani kufaneleama-transformer amanjeukuvinjelwa?

Kuwukuqinisekisa ukuphepha, okukodwa ukuphepha kwemishini, okwesibili ukuphepha komuntu siqu.
Kukhona ama-capacitor asatshalaliswe phakathi kokugoqa okuyinhloko kanye nokugoqa okwesibili kwe-ct kanye naphakathi kokugoqa okwesibili kanye nomhlabathi.
Isihlukanisi se-voltage sale capacitance esatshalaliswayo sibangela ukuthi ukugoqa kwesibili kukhiqize i-voltage ephezulu emhlabathini.
Ngaphezu kwalokho, ukufakelwa kwe-insulation phakathi kokugoba okuyinhloko kanye nokugoba kwesibili konakele ngenxa yezizathu ezithile, ngakho-ke i-voltage ephezulu yesekethe eyinhloko izongezwa ngqo kwisekethe yesibili, okuyingozi kakhulu emishinini yesibili kanye nokuphepha komuntu siqu.

Ngakho-ke, uhlangothi lwesibili lweCTkumele isekelwe, futhi iluphu yesibili inephuzu elilodwa kuphela lomhlabathi. Amaphuzu amaningi emhlabathini awavunyelwe.
