I-PT ne-CT kuma-Transformers: Amaqhawe Angashiwongo E-Voltage Namanje

I-PT ne-CT kuma-Transformers: Amaqhawe Angashiwongo E-Voltage Namanje

Uma kukhulunywa ngama-transformer,I-PT(I-Transformer Engaba Khona) kanyeI-CT(I-Current Transformer) ifana neqembu elinamandla lezwe likagesi—uBatman noRobin. Bangase bangazitholi izibani njenge-transformer uqobo, kodwa laba ababili basebenza ngemuva kwezigcawu ukuqinisekisa ukuthi konke kuhamba ngokuphepha nangokusebenza kahle. Ake singene endleleni abasebenzisa ngayo umlingo wabo ezimisweni ezahlukene ze-transformer.

I-PT: I-Voltage Whisperer

II-Transformer Engaba Khona (PT)ungumuntu othanda kakhulu ukwehlisa i-voltage ephezulu uye ezingeni elilawulekayo. Cabanga ukuthi ubhekene ne-33 kV enkulu kakhulu (noma ephakeme kakhulu) ohlelweni lwakho lwamandla—iyingozi futhi ngokuqinisekile akuyona into ongathanda ukuyilinganisa ngqo. Yilapho i-PT ingena khona. Iguqula lawo ma-voltage aphakamisa izinwele abe yinto amamitha akho nama-relay angayisingatha ngaphandle kokujuluka, ngokuvamile ayehlise abe yinto efana ne-110 V noma i-120 V.

Ngakho-ke, utholaphi ama-PT asebenza?

• Ama-transformer okudlulisa amandla aphezulu: Lezi yizibhamu ezinkulu zegridi yamandla, eziphatha ama-voltage noma kuphi kusukela ku-110 kV kuya ku-765 kV. Ama-PT lapha aqinisekisa ukuthi ungaqapha futhi ulinganise i-voltage ngokuphephile ukude.
• Ama-transformer eziteshini ezincane: Ama-PT asebenza eziteshini ezincane ukuze aqaphe futhi alawule amazinga kagesi ngaphambi kokuba asatshalaliswe kubathengi bezimboni noma bezindlu.
• Iziguquli zokuvikela nokulinganisaEzinhlelweni lapho ukuqapha i-voltage kubalulekile khona ekuphepheni nasekukhokhiseni, ama-PT ayangenelela ukuze anikeze ukufundwa kwe-voltage okunembile kwamakamelo okulawula, ama-relay, namadivayisi okuvikela.

I-PT ifana nomhumushi ozolile, oqoqene ekhonsathini kagesi enomsindo, ethatha lawo manothi e-110 kV ahlukanisa izindlebe bese ewaguqula abe umsindo omnene ongaphathwa yimishini yakho.

I-CT: I-Tamer Yamanje

Manje, ake sixoxe nge-I-Transformer Yamanje (CT), umqeqeshi womuntu siqu wesistimu yamandla. Lapho ugesi uqala ukunyakaza imisipha yawo ngezinkulungwane zama-amps ageleza nge-transformer yakho, i-CT iyangena ukuze iwulawule ufike ezingeni eliphephile—ngokuvamile ebangeni eliphakathi kuka-5 A noma u-1 A.

Uzothola ama-CT echitha isikhathi:

• Isiguquli Sokusabalalisas: Laba bantu bakhonza izindawo zokuhlala noma zezentengiselwano, ngokuvamile basebenza ngama-voltage afana ne-11 kV kuya ku-33 kV. Ama-CT lapha aqinisekisa ukuqapha nokuvikela kwamanje, eqaphela ukuthi ingakanani ijusi egeleza ngemigqa.
• Ama-Power Transformers eziteshini ezincane: Ama-CT aqapha ugesi ezindaweni zokushintshana kwamandla kagesi aphezulu lapho ama-transformer ehlisa khona amandla kagesi kusukela emazingeni okudlulisa (isb., 132 kV noma ngaphezulu) kuya emazingeni okusabalalisa. Abalulekile ekutholeni amaphutha nasekuqaliseni amadivayisi okuvikela ngaphambi kokuba kukhona okungahambi kahle.
• Ama-transformer ezimboni: Emafektri noma ezindaweni zezimboni ezisindayo, ama-transformer avame ukuphatha imithwalo emikhulu, kanti ama-CT akhona ukuqapha imisinga emikhulu. Uma kukhona okungahambi kahle, i-CT idlulisela ulwazi ezinhlelweni zokuvikela ezivala izinto ngaphambi kokuba imishini ithosiwe.

Cabanga nge-CT njengomshayeli wendiza ekilabhini—igcina ugesi ulawulwa ukuze ungakhungathekisi izinhlelo zakho zokuvikela, futhi uma izinto ziba zimbi kakhulu, i-CT iyaqinisekisa ukuthi othile ufika endaweni yokuma ephuthumayo.

Kungani i-PT ne-CT Kubalulekile

Ndawonye, ​​i-PT ne-CT zakha iqembu lamaphoyisa elihamba phambili emhlabeni we-transformer. Yizona zizathu ezenza opharetha bakwazi ukuqapha nokulawula ukusebenza kwe-transformer ngokuphephile ngaphandle kokusondela ngokoqobo esilweni (ngithembe, awufuni ukusondela kulolo hlobo lwe-voltage kanye nomsinga ngaphandle kokuvikelwa okungathi sína). Kungakhathaliseki ukuthi kuyi-i-transformer yokusabalalisaendaweni yakini nomai-transformer yamandla aphezuluAmandla okuhambisa kuwo wonke amadolobha, ama-PT nama-CT ahlala ekhona, okugcina i-voltage kanye nomsinga kusemgqeni.

Iqiniso Elijabulisayo: Ukuqaphela Izinhlangothi Zombili

Wake wazibuza ukuthi kungani ibhili lakho likagesi linembile kangaka? Ungabonga ama-CT nama-PT kuama-transformer okulinganisa. Baqinisekisa ukuthi inkampani kagesi kanye nekhasimende bayazi kahle ukuthi kusetshenziswe ugesi ongakanani ngokuhla ngokunembile nangokulinganisa i-voltage kanye nogesi wamanje. Ngakho-ke, yebo, i-PT kanye ne-CT zigcina izinto zilungile futhi zilingana kuzo zombili izinhlangothi zegridi yamandla.

Isiphetho

Ngakho-ke, kungakhathaliseki ukuthi i-transformer yokudlulisa ephakeme noma i-transformer yokusabalalisa esebenza kanzima,I-PT kanye ne-CTbangamaqhawe angakadunyiswa agcina yonke into isebenza kahle. Balawula amandla kagesi aphezulu kanye nemisinga emikhulu ukuze opharetha, ama-relay, kanye namamitha bakwazi ukuwaphatha ngaphandle kwesudi yeqhawe. Ngesikhathi esizayo uma uvula iswishi yokukhanya, khumbula—kukhona ithimba lonke labaqaphi bakagesi abaqinisekisa ukuthi amandla kagesi kanye namandla kagesi ayasebenza.
