Ngaphakathi kweKYN Switchgear Line-Up: Okungenayo, okuphumayo, uKhuselo kunye nokulinganisa, iPhaneli yiPaneli
Vula umnyango ka isixhobo sokutshintsha isixhobo sombane esiphakathi igumbi kwaye into yokuqala oyiqaphelayo kukuphindaphinda. Umqolo emva komqolo wecubicles zentsimbi, nganye imalunga nobubanzi obufanayo, nganye inephaneli yokulawula encinci ngaphambili kunye nomzobo olinganisayo okuxelela ukuba yenza ntoni cubicle. Ukuphindaphinda kubonakala kukruqula. Ayiyo. Loo mqolo yindlela igumbi lokuhambisa lihlala liphila xa impazamo yenzeke kwindawo esezantsi.
I-JSGK inikezela nge-KYN, i-XGN kunye neentsapho zekhabhinethi ezidibeneyo ezifakwe kwisinyithi ukuze zifumane, zisasazwe, zikhuselwe, zibekwe esweni kunye nokulinganisa. Eli nqaku lichaza ukuba isithuba ngasinye kumqolo senza ntoni ngokwenene, indlela iphaneli engaphambili ecwangciswe ngayo, kunye nento esiyijongayo phambi kokuba iicubicle ziwushiye umzi-mveliso.
Kutheni igumbi lidinga iicubicle ezininzi, kungekhona enye
Intambo enye engenayo ayifuni umqolo. Igumbi lokuhambisa lokwenyani lenza. Amandla afika kwi-feed enye okanye ngaphezulu engenayo, ehlala kwi-busbar eqhelekileyo, aze ahambe kwakhona ngokusebenzisa i-feeder ezininzi eziphumayo eziya kwii-transformers, amaziko okulawula iimoto okanye i-ring nodes. Umsebenzi ngamnye kuloo misebenzi ufumana eyakhe ityhubhile evalekileyo yesinyithi kuba umsebenzi ngamnye unomsebenzi owahlukileyo kunye nesetingi yokhuseleko eyahlukileyo.
Umgca womgca uzotywe kumzobo womgca omnye phambi kokuba ityhubhile enye idityaniswe. Lo mzobo ubiza ipaneli engenayo, icandelo lebhasi, i-feeder nganye ephumayo, indawo yokhuselo kunye nephaneli yokulinganisa. Kumgangatho wevenkile, imizobo yamalungiselelo ekhabhathi ilungisa ububanzi, ubunzulu, indawo yokufikelela ngaphambili kunye nendawo yokungena ngentambo ukuze umqolo ulingane negumbi lakho.
Izikhundla ezine oza kudibana nazo
- Iiphaneli ezingenayo (kunye necandelo lebhasi). Ezi zifumana unikezelo oluvela kwi-utility okanye i-transformer ephezulu kwaye idibanise kwi-busbar engundoqo. Iphaneli yecandelo lebhasi yahlula ibhasi ukuze iziqingatha ezibini zikwazi ukubaleka ngokuzimeleyo okanye ngokunxuseneyo.
- Iiphaneli eziphumayo. Ezi zithwala amandla kumthwalo ngamnye. I-feeder kwi-transformer, i-feeder kwi-motor, i-feeder kwiyunithi engundoqo yeringi, nganye yi-cubicle ephumayo ezinikeleyo kunye ne-switchgear yayo.
- Iiphaneli zokukhusela. Ezi zibamba iireyidi ezikhuselayo eziziva zigqithise, ukusilela komhlaba kunye nezinye iimeko ezingaqhelekanga kwaye zihamba ngesaphuli esifanelekileyo phambi kokuba usasazeke umonakalo. Izicwangciso zokudluliselwa zihambelana ne-feeder, azikhutshelwanga kumqolo wonke.
- Iiphaneli zokulinganisa. Ezi ziphethe izixhobo zokulinganisa kunye nemitha ezisetyenziselwa ukufunda amandla ombane, angoku, amandla kunye namandla, rhoqo ukondla intlawulo yenkonzo okanye inkqubo yamandla eplanti.
Igumbi elincinci linokudibanisa imisebenzi ethile kwiityhubhikliya ezimbalwa. Enkulu iphindaphinda iindawo ezingenayo kunye necandelo lebhasi ukwenzela ukhuseleko. Umzobo womgca omnye uyawugqiba.
Yintoni kanye ephambi kwekhabhinethi
Yima phambi kwe-cubicle ye-KYN kwaye iphaneli yangaphambili yenza umsebenzi, kungekhona ukuhlobisa. Uya kubona i-relay yokukhusela okanye isilawuli esinomboniso omncinci kunye namaqhosha e-push. Uya kubona imitha ye-analog okanye isixhobo sedijithali sombane kunye nangoku. Uza kubona izibane zesalathisi, ukutshintshwa kokulawula kunye nesibambo sokusebenza kwisixhobo sokutshintsha.
Ngezantsi kwezixhobo, umzobo olinganisayo ubonisa isiphaluka sokuqala kwi-miniature: apho i-busbar iqhuba khona, apho i-breaker ihlala khona, apho i-cable compartment iphuma khona. Xa umqhubi evula i-cubicle, i-mimic ixelela, ngokujonga nje, ukuba loo feeder ivaliwe okanye ikhutshiwe, ngaphandle kokuthinta nantoni na. Izitshixo, izivalo zeengcango kunye nezitshixo zomhlaba zicwangcisiwe ukuze ikhompatimenti ingavulwa ngelixa lisasebenza.
Ngaphakathi, i-cubicle iyahlula ibe ngamacandelo: i-breaker okanye i-switch compartment, i-busbar compartment, i-cable compartment kunye ne-low-voltage okanye i-second compartment yokulawula kunye nokukhusela i-wiring. Ukuzahlula kwenziwa ngabom. Impazamo kwelinye icandelo iqulethwe yimiqobo yesinyithi endaweni yokugubungela umqolo wonke.
Xa uhamba umqolo ogqityiweyo, khangela izinto ezintathu ezahlula umgca owakhelwe-uku-odola kuluhlu lwegeneric. Iingcango zekhompatimenti kufuneka zithwale izivalo ezivala izibonda eziphilayo xa isaphuli-mthetho sirhoxiswa. Ityhubhile nganye kufuneka ibe nokutshintsha okubonakalayo komhlaba okanye indawo yokubeka umhlaba kwikhompatimenti yekhebula ngaphambi kokuba kuqale umsebenzi. Kwaye ucango lwesibini kufuneka luvuleke ngaphandle kokukhulula nayiphi na i-high-voltage interlock. Ezi ziinkcukacha ezivumela injineli yolondolozo ukuba isebenze i-feeder ngokukhuselekileyo kwiminyaka emva kokugunyaziswa.
Izaphuli zesekethe, iibhasi kunye nesekethe yesibini
Into yokutshintsha kwikompathi yesekethe sisitshixo sesekethe (okanye ukulayisha-ikhefu lokutshintsha kwii-cubicle ezilula) ezinokuthi zenze, zithwale kwaye ziphule umthwalo wangoku, kwaye zihambe ngokuzenzekelayo phantsi kwesiphoso sangoku ngokuthumela ukhuseleko. Ibar yebhasi ephambili ngumqhubi oqhelekileyo obopha indawo yolawulo engenayo kuyo yonke ipaneli ephumayo; ukulinganisa kwayo kukhethwe ukuthwala igumbi elipheleleyo langoku kunye nomda.
Isekethe yesibini lulawulo, umqondiso kunye ne-wiring phakathi kwe-relays, izixhobo, i-pushbuttons kunye ne-breaker. Isebenza kwindawo yayo kwaye kulapho iziphene ezininzi zokuthumela ngaphandle zizimele khona. Icocekile, ibhalwe imiba yocingo lwesibini njengobhedu, kuba ireyiyi ekhubekisa umxhesho ongeyiyo iyabiza naxa ibhasi bar ilungile.
Indlela umqolo okhusela ngayo igumbi
Beka iziqwenga kunye nebali lokukhusela lilula. I-feeder ephumayo iphuhlisa isekethe emfutshane. Ukunyuka kwangoku. I-relay yokukhusela kweso sondlo ibona i-overcurrent kwaye ithumela uphawu lohambo kwi-breaker yayo. Eso saphuli-mthetho siyavula, sicoca kuphela i-feeder enempazamo ngelixa yonke ibhasi ihlala ihlala. Iphaneli engenayo kunye nezinye izixhasi zihlala zisebenza. Ngaphandle kweereyidi ezikumgangatho ofanelekileyo kunye ne-breaker ezinikeleyo kwi-feeder nganye, impazamo enye iya kuphosa igumbi lonke ebumnyameni.
Olo kuhlelwa koseto lokhuseleko, ukondla ngesondlo, kugqitywe kwidayagram yomgca omnye kwaye ihlolwe ngexesha lokuhlanganisa kunye nocingo lwesibini.
Ukuhlolwa okuqhelekileyo kunye nokuphumayo phambi kokuthunyelwa
Amasango amabini okuhlola ahlala phakathi komqolo ogqityiweyo kunye nesitya. Ukuhlolwa okuqhelekileyo kuqhuba njengoko iityhubhile zithatha ukuma, ukujonga isakhiwo ngokuchasene nomzobo. Ukuhlolwa okuphumayo kukuphumelela kokugqibela: ukutshekishwa kwe-dimensional, ukujonga i-coating, ukuhlolwa kwecandelo kunye nokukhangela ukuba i-wiring yesibini kunye ne-interlocks ziziphatha njengoko umzobo uthi. Iirekhodi zokuhlola kunye neerekhodi zovavanyo zilungiswa ngomyalelo, ngoko ke iqela lakho lesayithi kunye nomhloli wakho ozimeleyo banokufunda oko kuhlolwe.
Ulungelelwaniso lokugqibela lutshixiwe kwiinkcukacha zedatha ezivunyiweyo, imizobo yomgca omnye, imizobo yamalungiselelo ekhabhathi kunye nemigangatho yeprojekthi phambi kokuveliswa. Sixelele inqanaba lamandla ombane (iiklasi ze-10kV kunye ne-35kV ziqhelekile kulo mgca), umyinge wangoku, inqanaba lesekethe emfutshane, inani leesekethe eziphumayo kunye nokusingqongileyo kwesiza, kwaye siya kundlala umqolo ulungele igumbi lakho.
