Kutheni kufuneka elinye icala le-CT lisekelwe?

Ukugqitywa kwesibini kweisiguquli sangokukwaye i-transformer ye-voltage kufuneka ibekwe phantsi ngexesha lokusebenza, ukuze kuthintelwe ukuba i-voltage ephezulu ingangeni kwi-voltage ephantsi nge-transformer ngokulandelelana emva kokuba i-insulation ye-transformer yaphukile, nto leyo eya kwenzakalisa isixhobo kunye nabasebenzi bokusebenza. Ukufakwa kwesiseko sesibini se-transformer akuyi kuchaphazela ukusebenza okuqhelekileyo kwezixhobo, kodwa kuya kuqinisekisa ukhuseleko lwabasebenzi kunye nezixhobo.
Ukuqinisekisa ukhuseleko, icala lesibini le-CURRENT transformer kufuneka libekwe phantsi ukuze likhusele umzimba womntu kunye nezixhobo xa icala lesibini le-current transformer lisengozini ephezulu yombane.

Isiguquli sangokuisenzo

Kwinkqubo yokuvelisa, sijonga imeko yokusebenza kwesixhobo ngasinye kwinkqubo ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo yamandla.
I-transformer yangoku idla ngokuguqula umsinga omkhulu wesekethe eyintloko ibe ngumsinga omncinci wesibini ohambelana ngqo nawo, kwaye ekugqibeleni ikhuphe umsinga omncinci wesibini kwisixhobo sesibini, ukhuselo lokudluliselwa kunye nesixhobo esisebenzisa ngokuzenzekelayo.
Ke ngoko, i-current transformer ngumthombo wamandla ombane wolawulo lombane, ulawulo, umlinganiselo kunye nokhuseleko, kwaye ikwayindawo yonxibelelwano phakathi kwesekethe yesibini kunye nesekethe ephambili.

Kutheni icala lesibini le-CT lingenakuvuleka?
Ngenxa yokuba isekethe yesibini ye-CT ivuliwe, umsinga wesibini uya kunyamalala, kwaye ne-demagnetization nayo iya kunyamalala, nto leyo ebangela ukuba kubekho uxinano olukhulu lwemagnethi embindini.
Kwaye ngenxa yokuba inani leenguqu ezijikelezayo kwicala lesibini likhulu kakhulu kunenani leenguqu ezijikelezayo kwicala eliphambili, ngoko ke xa icala lesibini livuliwe, kuya kubakho i-voltage ephezulu elungileyo, ngamanye amaxesha ukuya kuthi ga kumawaka ee-volts, ngoko ke ayibeki emngciphekweni izixhobo zecala lesibini kuphela, kodwa ikwabeka emngciphekweni ukhuseleko lomntu.

Kutheni kufunekaii-transformer zangokuukuba abekwe phantsi?

Kukuqinisekisa ukhuseleko, enye kukhuseleko lwezixhobo, eyesibini kukhuseleko lomntu ngamnye.
Kukho ii-capacitors ezisasazekileyo phakathi kokujika okuphambili kunye nokujika okwesibini kwe-ct kunye naphakathi kokujika okwesibini kunye nomhlaba.
Isihluli sevolthi sale capacitance esasazekileyo sibangela ukuba ukujija kwesibini kuvelise ivolthi ephezulu emhlabeni.
Ukongeza, ubushushu phakathi kwe-primary winding kunye ne-secondary winding yonakele ngenxa yezizathu ezithile, ngoko ke i-voltage ephezulu ye-primary circuit iya kongezwa ngqo kwi-secondary circuit, nto leyo eyingozi kakhulu kwizixhobo zesibini kunye nokhuseleko lomntu.

Ke ngoko, icala lesibini leCTkufuneka isekelwe, kwaye iluphu yesibini inenqaku elinye kuphela lomhlaba. Amanqaku amaninzi omhlaba awavumelekanga.
