Ama-Transformer Afakwe Iphedi Yesigaba Esisodwa e-JZP: Ubunjiniyela Obunembile Bokusabalalisa Amandla Okuthembekile​

Emkhakheni wobunjiniyela kagesi, uhlelo lokusabalalisa lusebenza njengesixhumanisi esibalulekile phakathi kokudluliselwa kwamandla nokusetshenziswa kwawo. Ukuqonda okujulile kolwazi lokusabalalisa, ikakhulukazi mayelana ne-switchgear, kubalulekile konjiniyela nochwepheshe bakagesi. I-Switchgear iyithuluzi lokusabalalisa elihlanganisiwe elihlanganiswe ngokwezinhlelo ezithile zesekethe, elihlanganisa imishini eyinhloko (isb., amabha, ama-circuit breaker) kanye nemishini yesibili (isb., ama-relay, amamitha). Umsebenzi walo oyinhloko ukulawula nokuvikela imigqa yokusabalalisa kanye nemishini, ukuqinisekisa ukusebenza okuphephile nokuzinzile kwezinhlelo zamandla.

 

Ukuhlukaniswa kwe-Switchgear

I-Switchgear ingahlukaniswa ngezigaba ngokusekelwe ezidingweni zohlelo lokusebenza kanye namazinga e-voltage:

 

Ngokwesakhiwo: Izinhlobo zohlobo olungaguquki kanye nezinhlobo zenqola edonswa ngesandla.

 

Ngokwezinga leVoltage:

 

I-Switchgear Enamandla Aphezulu: Ifaka phakathi imiklamo engaguquki nengasuswa.

 

I-Switchgear Ene-Voltage Ephansi: Ifaka phakathi imiklamo engaguquki kanye neyohlobo lwedrowa.

 

Izingxenye Zesakhiwo se-Switchgear

I-Switchgear ngokuvamile ihlanganisa lezi zindawo ezilandelayo ezisebenzayo, ezihlukaniswe ngamapuleti ensimbi agqitshiwe ukuvimbela izifunda ezimfushane:

 

Igumbi Lamabhasi: Izindlu zamabhasi (abaqhubi bamabhasi).

 

Igumbi Lokuphula Isifunda: Liqukethe i-circuit breaker eyinhloko.

 

Igumbi Lokulawula Lesibili (Igumbi Lezinsimbi): Ama-relay ezindlu, amamitha, namadivayisi okulawula.

 

Igumbi Lokuphakela: Lixhumanisa ama-feeder aphumayo.

 

Izingxenye Eziyinhloko Zangaphakathi:

 

Amabhasi (abaqhubi bamabhasi)

 

Ama-circuit breaker

 

Ama-relay avamile

 

Amadivayisi okuvikela ahlanganisiwe

 

Amamitha

 

Ukushintsha okuhlukile

 

Izinkomba

 

Amaswishi okumba umhlaba

 

Izigaba Zokusebenza ze-Switchgear

​1. Ikhabhinethi Engenayo (Ikhabhinethi Yokungena)​​

Indima: Ithola ugesi ovela kugridi bese iwusabalalisa emishinini elandelayo ngama-circuit breakers, ama-CT (ama-Current Transformers), kanye nama-PT (Ama-Voltage Transformers).

 

Ukubaluleka: Kusebenza njengesixhumi esiyinhloko sokuxhumeka kwegridi.

 

​2. IKhabhinethi Ephumayo (IKhabhinethi Yokusabalalisa)​​

Indima: Isabalalisa ugesi osuka kubha yebhasi uye emigqeni ephumayo ngayinye, iqinisekisa ukunikezwa okuzinzile kwemishini yomsebenzisi wokugcina.

 

​3. Ikhabhinethi Yokuxhuma Ibha Yamabhasi​

Indima: Ixhumanisa izingxenye ezimbili zebhasi, isekela izinhlelo zebhasi elilodwa noma zebhasi eliphindwe kabili ukuze kube nokuguquguquka kokusebenza.

 

​4. Ikhabhinethi ye-PT (I-Transformer Engaba Khona IKhabhinethi)​​

Indima: Iqapha i-voltage ye-busbar futhi yenza kube lula izinhlelo zokuvikela. Ihlonyiswe ngama-PT, amaswishi okuhlukanisa, ama-fuse, kanye nezithiyo zokuvimba ukugeleza.

 

5. Ukuhlukaniswa kweKhabhinethi​

Indima: Ihlinzeka ngendawo yokunqamula ebonakalayo yokulungisa, ihlukanisa amabha amabhasi noma imishini emithonjeni kagesi. Idinga ukukhiywa nama-circuit breakers ukuvimbela ukusebenza ngengozi.

 

​6. IKhabhinethi Yesinxephezelo Se-Capacitor​

Indima: Kuthuthukisa amandla futhi kunciphisa ukungcola kwamandla ngokusebenzisa isinxephezelo samandla esisebenzayo.

 

7. Ikhabhinethi Yokulinganisa​

Indima: Ilinganisa ukusetshenziswa kwamandla (kWh) isebenzisa amamitha, ama-CT, ama-PT, namadivayisi asizayo njengezikrini zokulayisha.

 

​8. Ikhabhinethi ye-GIS (I-Switchgear Efakwe Ukushisa Ngegesi)​

Indima: Izinhlelo zokusebenza ezinama-voltage aphezulu/ezinomthamo ophezulu kusetshenziswa igesi ye-SF6 yokuvikela ukushisa, ukuqinisekisa ukuphepha okuthuthukisiwe kanye nokuthembeka.

 

Izingxenye Ezibalulekile Nezindima Zazo

I-Circuit Breaker

Umsebenzi: Uxhuma/unqamula amasekethe ngaphansi kwezimo ezijwayelekile futhi uphazamise ama-fault currents (isb., amasekethe amafushane).

 

Ukucima i-Arc: Kusebenzisa imidiya efana negesi ye-SF6, i-vacuum, noma uwoyela ukucima ama-arcs ngesikhathi sokunqamula.

 

Iswishi Yokuhlukanisa (Isixhumi)​​

Umsebenzi: Ihlukanisa ngokuphephile amasekethe ane-voltage ephezulu ukuze ilungiswe. Ayinawo amandla okuqeda ugesi; kumele isetshenziswe nama-circuit breaker.

 

I-Fuse

Umsebenzi: Kuvikela amasekethe ngokuncibilika uma ugesi uqhubeka, okudinga ukushintshwa ngemva kokusebenza.

 

Ukushintsha Umthwalo

Umsebenzi: Kuphazamisa ugesi ogcwele kodwa hhayi ama-short circuits. Ngokuvamile kuhlanganiswe nama-fuse ukuze kuvikelwe ugesi ongaphezu kogesi.

 

I-Transformer

Umsebenzi: Iguqula amazinga kagesi ngokufakwa kwe-electromagnetic. Amapharamitha abalulekile afaka umthamo olinganisiwe, isilinganiso se-voltage, kanye nokusebenza kahle.

 

Isiphetho

Ukwazi izimiso ze-switchgear—kufaka phakathi isakhiwo sayo, izingxenye zayo, kanye nezinhlelo zokusebenza—kubalulekile ekuqinisekiseni ukuthembeka nokuphepha kwezinhlelo zamandla.
