I-PT kunye ne-CT kwi-Transformers: IiNgwevu ezingadunyiswanga zeVoltage kunye ne-Current

Xa kufikwa kwiitransformers,I-PT(I-Transformer enokwenzekakunyeI-CT(iCurrent Transformer) zifana nesibini esitshintshayo sehlabathi lombane—uBatman noRobin. Basenokungaziboni izinto ezikhanyayo njengetransformer ngokwayo, kodwa aba babini basebenza ngasemva ukuqinisekisa ukuba yonke into isebenza ngokukhuselekileyo nangokufanelekileyo. Makhe sijonge indlela abasebenzisa ngayo umlingo wabo kwiisetingi ezahlukeneyo zetransformer.

PT: I-Voltage Whisperer

II-Transformer enokubakho (PT)yindoda oyithandayo ngokwehla i-voltage ephezulu ukuya kwinqanaba elilawulekayo. Khawuthelekelele ujongene ne-33 kV enkulu (okanye nangaphezulu) kwinkqubo yakho yamandla—iyingozi kwaye ngokuqinisekileyo ayiyonto ubungathanda ukuyilinganisa ngokuthe ngqo. Kulapho i-PT ingena khona. Iguqula loo voltage inyusa iinwele ibe yinto enokusingathwa ziimitha zakho kunye neerelay ngaphandle kokubila, idla ngokuyihlisa iye kwinto efana ne-110 V okanye i-120 V.

Ngoko ke, ufumana phi ii-PT ezisebenzayo?

• Iitransformer zothumelo oluphezulu: Ezi zizibhamu ezinkulu zegridi yamandla, ezilawula iivoltage naphi na ukusuka kwi-110 kV ukuya kwi-765 kV. IiPT apha ziqinisekisa ukuba unokujonga kwaye ulinganise ivoltage ngokukhuselekileyo ukude.
• Iitransformer zesitishi esingaphantsi: Ii-PT zisebenza kwizikhululo ezincinci ukujonga nokulawula amanqanaba ombane ngaphambi kokuba asasazwe kubathengi bemizi-mveliso okanye bezindlu.
• Ukhuselo kunye nee-metering transformers: Kwiinkqubo apho ukujonga i-voltage kubalulekile kukhuseleko kunye nokuhlawulisa, ii-PT zingenelela ukubonelela ngokufundwa kwe-voltage ngokuchanekileyo kumagumbi olawulo, ii-relay, kunye nezixhobo zokukhusela.

I-PT ifana nomguquleli ozolileyo noqokelelweyo kwikonsathi yombane enomsindo, ethatha loo manqaku e-110 kV aqhekezayo iindlebe aze awaguqule abe yingxolo ethambileyo enokuthwalwa zizixhobo zakho.

I-CT: I-Tamer yangoku

Ngoku, masithethe ngeI-Transformer yangoku (CT), umqeqeshi wobuqu wenkqubo yamandla. Xa umsinga uqala ukuthulula izihlunu zawo kunye namawaka ee-amps ezihamba kwi-transformer yakho, i-CT iyangenelela ukuze iwuthobe uye kwinqanaba elikhuselekileyo—ngesiqhelo kumgama we-5 A okanye i-1 A.

Uza kufumana iiCTs zihleli apha:

• Isiguquli soSasazos: Aba bantu bakhonza iindawo zokuhlala okanye zorhwebo, ngokuqhelekileyo basebenza kwiivoltheji ezifana ne-11 kV ukuya kwi-33 kV. IiCT apha ziqinisekisa ukubekwa esweni nokukhuselwa kwangoku, zigcina iliso kubungakanani bejusi egeleza kwiintambo.
• Iitransformer zamandla kwizikhululo ezingaphantsi: Ii-CT zijonga umbane kwizikhululo zombane eziphezulu apho ii-transformers zinciphisa umbane ukusuka kumanqanaba othumelo (umz., i-132 kV okanye ngaphezulu) ukuya kumanqanaba osasazo. Zibalulekile ekufumaneni iimpazamo kunye nezixhobo zokukhusela ngaphambi kokuba kubekho into engalunganga.
• Iitransformer zemizi-mveliso: Kwimizi-mveliso okanye kwiindawo zoshishino ezinzima, ii-transformers zihlala zithwala imithwalo enzima, kwaye ii-CT zikhona ukuze zijonge imisinga emikhulu. Ukuba kukho into engahambanga kakuhle, i-CT idlulisela ulwazi kwiinkqubo zokhuseleko ezivala izinto ngaphambi kokuba izixhobo ziqhotswe.

Cinga nge-CT njenge-bouncer eklabhu—igcina umsinga ulawuleka ukuze ungagqithisi iinkqubo zakho zokhuseleko, kwaye ukuba izinto ziba ziingxolo kakhulu, i-CT iyaqinisekisa ukuba umntu ufika kwindawo yokumisa engxamisekileyo.

Kutheni i-PT kunye ne-CT zibalulekile

Xa bebonke, i-PT kunye ne-CT zenza i-duo yamapolisa angcono kwihlabathi le-transformer. Zizo ezibangela ukuba abaqhubi bakwazi ukujonga nokulawula ukusebenza kwe-transformer ngokukhuselekileyo ngaphandle kokusondela ngqo kwisilwanyana (ndikholelwe, awufuni ukusondela kuloo hlobo lwe-voltage kunye nomsinga ngaphandle kokhuseleko olunzulu). Nokuba yi-isiguquli sokusasazakwindawo ohlala kuyo okanyeisiguquli samandla esinombane ophezuluAmandla okondla kuzo zonke izixeko, ii-PT kunye nee-CT zihlala zikhona, zigcina i-voltage kunye nomsinga zihambelana.

Inyani Eyonwabisayo: Ukugcina Iliso Kuzo Zombini Iincam

Wakha wazibuza ukuba kutheni ityala lakho lombane lichane kangaka? Ungabulela iiCT kunye neePTs kwiii-transformer zokulinganisaBaqinisekisa ukuba inkampani yombane kunye nomthengi bayazi kakuhle ukuba umbane ongakanani osetyenziswayo ngokuhla ngokuchanekileyo nokulinganisa i-voltage kunye nomsinga. Ngoko ke, ewe, i-PT kunye ne-CT zigcina izinto zilungile kwaye zilingana kuzo zombini iziphelo zegridi yombane.

Isiphelo

Ngoko ke, nokuba yitransformer ende yokudlulisa umbane okanye yitransformer yokusasaza esebenza nzima,I-PT kunye ne-CTziiqhawe ezingadunyiswanga ezigcina yonke into isebenza kakuhle. Zilawula i-voltage ephezulu kunye nemisinga emikhulu ukuze abaqhubi, ii-relay, kunye neemitha bakwazi ukuziphatha ngaphandle kwesuti ye-superhero. Ngexesha elizayo xa uvula iswitshi yesibane, khumbula—kukho iqela lonke labagcini bombane abaqinisekisa ukuba i-current kunye ne-voltage ziyaziphatha.
