Iitransformer ezifakwe kwi-pad ze-JZP ezineSigaba esinye: Ubunjineli obuchanekileyo bokusasazwa kwamandla okuthembekileyo

Kwicandelo lobunjineli bombane, inkqubo yokusasaza isebenza njengekhonkco elibalulekileyo phakathi kokudluliselwa kwamandla kunye nokusetyenziswa kwawo. Ukuqonda okunzulu kolwazi lokusasaza, ngakumbi malunga neswitchgear, kubaluleke kakhulu kwiinjineli zombane kunye neengcali. Iswitchgear sisixhobo sokusasaza esidibeneyo esihlanganiswe ngokwezicwangciso ezithile zesekethe, sidibanisa izixhobo eziphambili (umz., iibhasi, ii-circuit breakers) kunye nezixhobo zesibini (umz., ii-relay, iimitha). Umsebenzi wayo oyintloko kukulawula nokukhusela imigca yokusasaza kunye nezixhobo, ukuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kweenkqubo zamandla.

Iiswitshi zokumba umhlaba

 

Iindidi zomsebenzi zeSwitchgear

​1. Ikhabhinethi engenayo (Ikhabhinethi yokungena)​​

Indima: Ifumana umbane kwigridi ize iwusasaze kwizixhobo ezilandelayo ngokusebenzisa ii-circuit breakers, ii-CT (ii-Current Transformers), kunye nee-PT (Iitransformer zeVoltage).

 

Ukubaluleka: Isebenza njengonxibelelwano oluphambili lonxibelelwano lwegridi.

 

​2. IKhabhinethi ephumayo (IKhabhinethi yoSasazo)​​

Indima: Ukusasaza umbane ukusuka kwibha yebhasi ukuya kwimigca ephumayo nganye nganye, ukuqinisekisa ukunikezelwa okuzinzileyo kwizixhobo zomsebenzisi wokugqibela.

 

3. Ikhabhinethi yokudibanisa iibhasi

Indima: Idibanisa amacandelo amabini ebhasi, ixhasa iinkqubo zebhasi enye ezibekwe kwicandelo okanye iibhasi ezimbini ukuze kube lula ukusebenza.

 

4. Ikhabhinethi yePT (I-Transformer enokwenzeka IKhabhinethi)​​

Indima: Ijonga i-voltage ye-busbar kwaye yenza kube lula iinkqubo zokukhusela. Ixhotyiswe ngee-PT, ii-switches zokwahlulahlula, ii-fuse, kunye nezithinteli zokushushuluza.

 

5. Ukuzahlula iikhabhinethi

Indima: Ibonelela ngendawo ebonakalayo yokukhupha umbane xa kulungiselelwa, ikhupha iibhasi okanye izixhobo kwimithombo yamandla. Ifuna ukuvalelwa nee-circuit breakers ukuthintela ukusebenza ngengozi.

 

6. Ikhabhinethi yeMbuyekezo yeCapacitor

Indima: Iphucula amandla kwaye inciphisa inkunkuma yamandla ngokusebenzisa imbuyekezo yamandla esebenzayo.

 

7. Ikhabhinethi yokulinganisa

Indima: Ukulinganisa ukusetyenziswa kwamandla (kWh) usebenzisa iimitha, ii-CT, ii-PT, kunye nezixhobo ezincedisayo ezifana neemonitha zomthwalo.

 

8. Ikhabhinethi ye-GIS (iSwitchgear efakwe igesi)​

Indima: Usetyenziso olusebenzisa amandla aphezulu/umthamo ophezulu olusebenzisa igesi ye-SF6 ukuthintela ubushushu, ukuqinisekisa ukhuseleko oluphuculweyo kunye nokuthembeka.

 

Izinto ezibalulekileyo kunye neendima zazo

Umqhekezi weSekethe

Umsebenzi: Uqhagamshela/ukhupha iisekethe phantsi kweemeko eziqhelekileyo kwaye uphazamise imisinga yempazamo (umz., iisekethe ezimfutshane).

 

Ukucima i-Arc: Isebenzisa izixhobo ezifana negesi ye-SF6, i-vacuum, okanye i-oyile ukucima ii-arcs ngexesha lokucima.

 

Iswitshi Yokwahlukanisa (Isixhumi)​

Umsebenzi: Iyawahlukanisa ngokukhuselekileyo amasekethe anombane ophezulu ukuze agcinwe. Ayinawo amandla okuqhekeza umbane; kufuneka isetyenziswe nama-circuit breakers.

 

Ifusi

Umsebenzi: Ikhusela iisekethe ngokunyibilika xa umsinga ogqithisileyo uqhubeka, nto leyo efuna ukutshintshwa emva kokusebenza.

 

Utshintsho lomthwalo

Umsebenzi: Iphazamisa ukugqithisa imisinga kodwa hayi ii-short circuits. Idla ngokudityaniswa nee-fuse zokukhusela i-overcurrent esisiseko.

 

I-Transformer

Umsebenzi: Iguqula amanqanaba ombane ngokusebenzisa i-electromagnetic induction. Iiparameter eziphambili ziquka umthamo olinganisiweyo, umlinganiselo wombane, kunye nokusebenza kakuhle.

 

Isiphelo

Ubuchule bemigaqo yeswitshi—kuquka ulwakhiwo lwayo, izinto ezisetyenziswayo, kunye nokusetyenziswa kwayo—bubalulekile ekuqinisekiseni ukuthembeka nokhuseleko lweenkqubo zamandla.
