Ama-transformer amanje, ngokuvamile kubizwa ngokuthiAma-CT, ziyizingxenye ezibalulekile ezinhlelweni zamandla. Idlala indima ebalulekile ekuvikelweni nasekulinganisweni kwezicelo, ngokungafani nama-transformer ajwayelekile. Kulesi sihloko, sizohlola umehluko phakathi kwama-CT nama-transformer ajwayelekile futhi sifunde ukuthi ama-CT asetshenziswa kanjani ekuvikeleni.
Okokuqala, ake sihlole umehluko phakathi kwama-CT nama-transformer avamile. Ama-transformer avamile aklanyelwe kakhulu ukudlulisa amandla kagesi phakathi kwamasekethe ngokwandisa noma ukunciphisa amazinga kagesi. Asetshenziswa kakhulu kumanethiwekhi okusabalalisa, i-voltage ikhushulwa ukuze idluliswe emabangeni amade kanti i-voltage yehliswa ukuze isetshenziswe ngabathengi.
Ngokungqubuzanayo,ama-transformer amanjezenzelwe ngqo ukukala noma ukuqapha ukugeleza kwamandla kagesi esijikelezweni sikagesi. Isebenza ngesimiso sokungeniswa kwamandla kagesi, njenge-transformer evamile. Kodwa-ke, ukugoqa okuyinhloko kwe-CT kuqukethe ukujika okukodwa noma ukujika okuningana, okuvumela ukuthi kuxhunywe ngokulandelana nomqhubi othwala amandla kagesi. Lo mklamo wenza kube lulaCTukukala imisinga ephezulu ngaphandle kokulahlekelwa amandla okukhulu. Ukugoqa kwesibili kwe-CT kuvame ukulinganiselwa ku-voltage ephansi, okwenza ithuluzi noma idivayisi yokuvikela iphephe kakhulu.
Manje, ake siqhubekele ekubalulekeni kwe-CT ekusetshenzisweni kokuvikela. I-CT isetshenziswa kabanzi ezinhlelweni zikagesi ukuqinisekisa ukuphepha kwemishini, amasekethe kanye nabasebenzi. Badlala indima ebalulekile ekutholeni amaphutha, ama-overcurrent kanye nezimo zokusebenza ezingavamile. Ngokulinganisa ngokunembile ama-current, i-CT iqalisa idivayisi yokuvikela ehlukanisa ingxenye enephutha ohlelweni lonke, ivimbele noma yimuphi umonakalo owengeziwe.
Ithuluzi elivamile lokuvikela elisetshenziswa kanye ne-CTs liyi-ukudluliselwaI-relay inesibopho sokuqapha inani lamanje kanye nokuqala ukuvulwa noma ukuvalwa kwe-circuit breaker ngokusekelwe kuzilungiselelo nezimo ezichazwe ngaphambilini. Isibonelo, uma kwenzeka i-short circuit noma i-overdose current, i-relay ithola lokhu okungajwayelekile bese ithumela isignali yokuhamba ku-circuit breaker.CTkuqinisekisa ukuthiukudluliselwaithola ukumelwa okunembile komsinga ogeleza ngesekethe, okuholela ekuvikelweni okuthembekile.
Ama-CTzisetshenziselwa futhi ukukala nokuqapha amapharamitha kagesi. Ezinhlelweni zamandla, kubalulekile ukwazi inani eliqondile lamandla ageleza kumasekethe ahlukahlukene. I-CT ivumela ukulinganisa okunembile, iqinisekisa ukuphathwa kwamandla okuphumelelayo kanye nemithwalo elinganiselayo. Lezi zilinganiso zingasetshenziswa ekukhokhiseni, ekuphathweni kwamandla kanye nasekugcinweni kokuvimbela.
Ngaphezu kwalokho, ama-CT asetshenziswa kabanzi ezisetshenziswa ezimbonini nasemishinini enemithwalo emikhulu kagesi. Ahlinzeka ngendlela yokuqapha amazinga amanje nokuthola noma yikuphi ukungahambi kahle, njengokugcwala ngokweqile kwenjini noma ukwehla kwamandla kagesi. Ngokubona ngokushesha lezi zinkinga, izinyathelo zokuvimbela zingathathwa ukuze kugwenywe ukwehluleka kwemishini okubizayo noma isikhathi sokungasebenzi.
Ngamafuphi, yize kokubili i-CT kanye nama-transformer avamile esebenza ngesimiso sokungeniswa kwe-electromagnetic, asebenza ngezinjongo ezahlukene. Ama-CT aklanyelwe ukulinganisa nokuvikela okwamanje. Umklamo wawo oyingqayizivele uwenza ukwazi ukukala ngokunembile imisinga ephezulu ngenkathi unikeza umphumela ophephile, ohlukanisiwe wezinsimbi kanye nemishini yokuvikela. Kungakhathaliseki ukuthi ithola amaphutha, iqinisekisa ukuphepha kukagesi noma iqapha ukusetshenziswa kwamandla, i-CT idlala indima ebalulekile ezinhlelweni zikagesi zanamuhla. Amakhono ayo okufunda okwamanje anembile kanye nokusebenza okuthembekile kuyenza ibe yingxenye ebalulekile ezimbonini nasezinhlelweni ezahlukahlukene.
