Ukufakwa kwamandla kungumgogodla wamanethiwekhi okusatshalaliswa kagesi, naseminyakeni yakhe yobumbano ezintweni ezimbili ezibucayi:isingeluna-Ama-ring amayunithi main(Rmus).
Yini i-switchchgear?
IsingeluIngabe igama elibanzi elihlanganisa ukushintshwa kukagesi ukunqamula, ama-fuse, kanye nabaqhekezi bejikelezo elenzelwe ukulawula, ukuvikela, nokuhlukanisa imishini kagesi.
Izinhlobo ze-switchchear
I-switchgear ihlukaniswe ngamazinga we-voltage:
- I-Voltage Voltage switchchear ephansi (LV): Kufika ku-1 kV, elungele izindawo zezimboni.
- I-Medium Voltage switchchear (MV): 1 KV kuya ku-36 kV, esetshenziswa kakhulu ekuzinikelweni kwezinto.
- I-High Voltage switchchear (HV): Ngaphezulu kwama-36 kV, kubalulekile ezinhlelweni zokudlulisela.
I-switchgear ingafakwa inyuselwa umoya, igesi (GIS), noma i-SOOL-insud, ngakunye okunikezela ngezinzuzo ezihlukile.
Yiliphi iyunithi eliphambili lendandatho (RMU)?
AI-Ring Main Unit (RMU)iyi-compact, efakwe ngokugcwele isethi ye-switchgear esetshenziswa kumanethiwekhi okusatshalaliswa kwamandla aphakathi nendawo.
Izici ezibalulekile ze-RMUS
- Izinketho zegesi ezifakwe igesi noma ezifakwe umoya.
- Idizayini yemodemu yokufakwa okulula nokwanda.
- Imvamisa ifaka ama-feeders amabili angenayo kanye nesiphakelayo esisodwa esiphumayo.
- Amadivayisi wokuvikela owakhelwe ngaphakathi kanye nezinkomba zephutha zokutholwa okusheshayo.
I-RMUS Xhuma okufakwayo okuningi ku-loop, ukuqinisekisa ukwehla.
I-switchgear ne-rmus isebenza kanjani ndawonye ezingeni
Ku-Power Performation, i-switchgear and rmus collcorate ku:
- Vikela imishini: Ukuvikela ama-transformers kanye nezinye izimpahla ezivela ekugcwalisekeni nasemaphutheni.
- Nika amandla ukulungiswa okuphephile: Hlukanisa izingxenye zenethiwekhi ukuze zilungiswe ngaphandle kokuphazamisa lonke uhlelo.
- Qinisekisa ukuthembeka: Thola ngokuzenzakalelayo futhi uhlukanise amaphutha ukuze ulondoloze ukugeleza kwamandla okuqhubekayo.
- Lungiselela ukuphathwa komthwalo: Lawula futhi ulinganise ukusatshalaliswa kwamandla kunethiwekhi.
Ukuhlanganiswa kwabo kubalulekile ekusebenzeni kahle kokusebenza kanye nokuqina kwegridi.
Izinzuzo ze-switchchear yanamuhla ne-RMUS
Lezi zingxenye zinikeza izinzuzo eziningana ezinhlelweni zanamuhla zamandla:
- Ukuphepha okuthuthukile: Ukufakwa okuvaliwe kanye nezingxenye ezifakiwe kunciphisa ubungozi be-arc flash.
- Ukusebenza kahle kwesikhala: Imiklamo ehlanganisiwe ilingana ezindaweni eziminyene noma zezimboni.
- Ukulungiswa okuphansi: Izakhi ze-modular zenza lula ukuhlinzeka futhi zinciphise izindleko.
- Ukwethembeka okuthuthukisiwe: Ukutholwa kwephutha okuzenzakalelayo kunciphisa ukuphuma nokukhulisa ukuqina kwegridi.
Izinhlelo zokusebenza zangempela zomhlaba
I-switchgerear nama-rmus athunyelwa kuyo yonke imikhakha ehlukahlukene:
- Izinto ezibalwayo: Kubalulekile ekusetshenzisweni kokusatshalaliswa kukagesi kokulethwa kwamandla okuthembekile.
- Amandla avuselelekayo: Phatha ukuhlanganiswa kwamandla welanga nomoya kugridi.
- Ama-Smart grids: Kubhangqiwe nezinzwa ze-IOT zokuqapha kanye nokulawula kwangempela.
- Izakhiwo Zentengiso: Qinisekisa amandla angaphazanyiswa ezindaweni ezifunwa kakhulu.
Kungani ukhethe i-switchchear efanelekile nenhlanganisela ye-rmu?
Ukukhetha ukusetha okufanele kwe-switchchear ne-RMU kubalulekile ku:
- Ubuhle obusebenza kahle: Izisombululo ezihambisana nazo zihlangabezana nezidingo ezithile ze-voltage kanye nezidingo zokulayisha.
- Ukusebenza kwezindleko: Gwema ukusebenzisa ngokweqile izici noma amakhono angadingekile.
- Ukufakazelwa Okuzayo: Imiklamo ejwayelekile ivumela ukuthuthukiswa okulula njengoba izidingo zivela.
I-Switchgetgear ne-RMUS amaqhawe angasebenzi ama-power athobeli, aqinisekise ukuqina, ukuphepha kanye nokusebenza kahle ekusatshalalisweni kukagesi.
