I-RMU iqhudelana ne-Full Switchgear, kanye ne-Box Substation vs Igumbi Elakhiwe: Ukuhweba Okusebenzayo
Imibuzo emibili ivela cishe kuzo zonke izingcingo zokuqala. Okokuqala ukuthi iphoyinti le-medium-voltage lidinga iyunithi eyinhloko eyindandatho noma umugqa ogcwele we-switchgear. Okwesibili ukuthi i-node yonke kufanele ifike njengebhokisi, ize njenge-a ikhabethe elenziwe ngaphambili, noma kwakhiwe njengendawo yokusabalalisa izitini esizeni. Imibuzo emibili ixhumene. Phendula eyokuqala neyesibili ivamise ukuzincisha yona.
Lesi sihloko sibeka ukuhwebelana ngamagama alula: i-footprint, yini eshayela izindleko, ukuthi ukhetho ngalunye lushesha kangakanani ikhomishini, kanye nezimo lapho umuntu ewina khona. Sakha konke, ngakho-ke ayikho impendulo ekhethwayo ngaphandle kwaleyo edingwa yisayithi lakho.
Khalisa iyunithi eyinhloko ngokumelene ne-switchgear egcwele
Iyunithi eyinhloko eyindandatho ikhabethe lokusabalalisa elihlangene elakhelwe izikimu zekhebula kanye namanodi enethiwekhi yamasongo. I-JSGK iwahlinzeka ngamalungiselelo e-gas-insulated (GIS) ngokushintshwa komthwalo. Mancane, avaliwe futhi ahloselwe inani elilinganiselwe lamasekhethi ekhebula lapho ukuvikela kunesizotha futhi isikhala siqinile. Cabanga ngomphakeli wezindlu, iluphu yezinsiza, indawo yekhampasi ehlangene.
Ulayini ogcwele we-high-voltage switchgear uyisilwane esihlukile. I-KYN, i-XGN kanye nomugqa wekhabhinethi ohlobene nensimbi ohlobene wezinhlelo ezingenayo, eziphumayo, zokuvikela kanye nezamamitha. Iphethe amasekhethi engeziwe, ukudluliselwa kokuvikela okwengeziwe, ibha yebhasi yangempela, kanye nezikhundla ezizinikele ezingenayo nezamamitha. Idinga igumbi, indawo yokungena ngaphambili kanye nemvume yokulungisa.
Khetha iyunithi eyinhloko yeringi lapho umsebenzi ulula: indawo yokukhala, izintambo ezimbalwa, asikho isidingo sokuvikela okugcwele kanye ne-metering suite. Khetha i-switchgear egcwele lapho igumbi liphakela ama-transformer, amamotho noma isitshalo, lapho ukugreda kubalulekile, nalapho inani lamasekhethi aphumayo likhula.
Ukuhwebelana emgqeni owodwa: i-RMU ikuthengela ukuminyana nesivinini, i-switchgear ikuthengela isibalo sesekhethi nokujula kokuvikela.
Ibhokisi lesiteshi esincane ngokumelene negumbi lokusabalalisa elakhelwe endaweni
Manje umbuzo wesibili. Isiteshi esincane sohlobo lwebhokisi sihlanganisa i-transformer, ikhabethe lamandla kagesi aphezulu, ikhabethe lamandla kagesi aphansi, indawo evalekile namasistimu asizayo kube yiyunithi eyodwa yangaphandle. Ifika ngeloli, ihlale esisekelweni esincane, futhi ixhunywe amakhebula esizeni.
Igumbi lokusabalalisa elakhelwe endaweni liwumzila wendabuko: igumbi likakhonkolo noma lezitini elakhiwe kuphrojekthi, bese lifakwa amakhabethe, izindawo zokuphuzela amabhasi, ukungena komoya kanye nokuvikela umlilo ngokuhweba kwesayithi.
Isiteshi esingaphansi sohlobo lwebhokisi siwina ngokulandela izinyathelo kanye nesivinini sokusebenza. Ithatha iphedi elincane, idinga umsebenzi omncane womphakathi, futhi ihlolwa efekthri ngaphambi kokuba ihambe, ngakho-ke ukugunyazwa ngokuvamile kuwukubambisa kanye nokunika amandla. Kungokwakhona okuzenzakalelayo kwamanodi okusabalalisa angaphandle, amasayithi wamandla amasha namaphrojekthi ngewashi.
Igumbi elakhiwe liwina ngokuguquguquka nokuhlala unomphela. Uma ulindele ukuthi umthwalo ukhule ngezindlela ezingaziwa, uma isayithi linomhlaba omningi, noma uma insiza idinga igumbi elihlala njalo, isakhiwo esikusayithi singanwetshwa futhi sihlelwe kabusha. Izindleko zayo ziqhutshwa imisebenzi yomphakathi, ukuhwebelana okumanzi kanye nomsebenzi wamakhono okufanele wenzeke endaweni evulekile, uma isimo sezulu sivuma. Ukusebenza kwayo kuhamba kancane ngoba isakhiwo, bese ukufakwa, kwenzeka ngokulandelana.
Igebe lokugunyazwa yilapho abathengi bezizwa bekhetha kakhulu. Isiteshi esincane sebhokisi noma ikhabethe lihlolwa njengasekuqaleni ngaphambi kokuthi lihanjiswe, ngakho-ke umsebenzi wesayithi uyisisekelo, ukubekwa, ukunqanyulwa kwekhebula kanye nokunikeza amandla. Igumbi elakhiwe lithwala umthwalo wokuhlola esizeni, ngemva kokuba izindonga seziphakanyisiwe namakhabethe afakiwe, okwengeza amasonto futhi kudalule isimiso esimweni sezulu kanye nokutholakala kosonkontileka abancane. Kuphrojekthi enedethi egxilile yokunika amandla, lelo gebe lilodwa ngokuvamile linquma ukukhetha.
Inketho ephakathi: ikhabethe likagesi elakhiwe ngaphambili
Kukhona indlela yesithathu abathengi abangayiboni. Ikhabethe likagesi elakhiwe ngaphambilini liyigumbi likagesi elakhiwe efekthri lezimpahla zokushintsha, amaphaneli okuvikela kanye namasistimu asizayo. Mkhulu kunesiteshi esingaphansi kwebhokisi kodwa ilethwa ngendlela efanayo: yakhiwe, yafakwa izintambo, yahlolwa futhi yapakishwa embonini yethu, bese ithunyelwa njengemojula ekwazi ukuthuthwa.
Ikhabethe lihlala phakathi kwalezi zimo ezimbili ezidlulele. Ikunikeza isakhiwo esifana negumbi kanye nokufinyelela ngaphambili kwegumbi lokusabalalisa elakhiwe, kodwa ngokumiswa okusheshayo nomsebenzi omncane oseceleni wesayithi womkhiqizo wefekthri. Amayunithi afika eselungiselelwe kakhulu ngokwefekthri; esizeni babopha ndawonye futhi baxhumane, nomsebenzi wokuhweba onamakhono amancane kakhulu. Zakhelwe ukuthi zikwazi ukugudluzwa futhi ziphinde zisetshenziswe, okubalulekile uma iphrojekthi ithatha iminyaka bese idilizwa.
Khetha ibhokisi lesiteshi elincane lenodi ehlangene, yangaphandle, ye-transformer-plus-switchgear. Khetha ikhabethe elakhiwe ngaphambili uma udinga igumbi langempela le-switchgear kodwa awukwazi ukulinda ukwakhiwa kwezitini. Khetha igumbi elikusayithi kuphela lapho isakhiwo silungisiwe ngempela, indawo ishibhile futhi uhlelo luvumela umsebenzi womphakathi omanzi.
Abashayeli bezindleko zokukala kusenesikhathi
Izindleko azihlali enanini lekhabhinethi yodwa. Ngesiteshi esincane sebhokisi noma ikhabethe, ukhokhela ukulungiswa kwefekthri, ukupakisha impahla ethunyelwa kwamanye amazwe kanye nendawo encane, nokonga emisebenzini yomphakathi kanye nasemsebenzini. Ngegumbi elakhiwe, uhweba ngebhili yempahla encane kakhonkolo, ukufulela, ukungena komoya, izicishamlilo kanye nefasitela elide lokwakha. Ukuthuthwa kwempahla nakho kubalulekile: ibhokisi lesiteshi esincane kanye nekhabhini kupakishwa ngokuqinile ukuze kuthunyelwe ngaphandle, okwehlisa izindleko ezilethiwe endaweni ngayinye endaweni ekude noma yaphesheya kwezilwandle.
Lapho inketho ngayinye iwina
- RMU: ama-node enethiwekhi, amakhebula ahlangene, umsebenzi wokuvikela okhawulelwe.
- I-switchgear egcwele: izitshalo, iziteshi ezincane, iziphakeli eziningi eziphumayo, ukugreda kokuvikela kuyadingeka.
- Isiteshi esingaphansi sohlobo lwebhokisi: izindawo zokusabalalisa zangaphandle, iziza zamandla amasha, amandla asheshayo.
- Ikhabethe elakhiwe ngaphambilini: igumbi le-switchgear elidingekayo ngokushesha, noma indawo okufanele ithuthwe kamuva.
- Igumbi elakhelwe endaweni: isakhiwo esimisiwe unomphela, indawo eyanele, akukho ukucindezela kweshejuli.
Sithumele uhlobo lwe-node, umthamo we-transformer, inani lamasekethe aphumayo kanye nemvelo yesayithi. Sizobonisa ukuthi iyiphi inketho elingana nendawo, iwashi kanye nesabelomali, futhi siyicaphune ngqo njengasekuqaleni.
