>>> Uhlolojikelele Lomkhiqizo
Uchungechunge lwe-XGW-12 olungaphandle lwesiteshi sokushintsha uhlobo lwebhokisi oluhlakaniphile luthatha isakhiwo sohlobo lwebhokisi langaphandle futhi luqukethe izinto zikagesi ezifana namakhabethe agcwele igesi e-SF6 kanye nama-DTU. Iyunithi eyinhloko yendandatho iyisethi ye-switchgear ephezulu efakwe ebhokisini lensimbi noma ehlanganiswe ibe yiyunithi yokuphakela amandla eyinhloko yohlobo lwe-bay. Izingxenye zayo eziyinhloko zihlanganisa ukushintsha komthwalo kanye nama-circuit breaker, anikeza izinzuzo ezifana nesakhiwo esilula, usayizi omncane, izindleko eziphansi, amapharamitha wokuphakelwa kwamandla okuthuthukisiwe nokusebenza, kanye nokuphepha okuthuthukisiwe kokunikezwa kwamandla. Isetshenziswa kakhulu eziteshini zokusabalalisa kanye neziteshi ezincane zohlobo lwebhokisi ezindaweni zokulayisha ezifana nezindawo zokuhlala zasemadolobheni, izakhiwo eziphakeme, izakhiwo zomphakathi ezinkulu, izimboni, kanye namabhizinisi.
Ukushintsha iziteshi ngokuvamile kuklanywa ngemigqa emibili engenayo nemigqa eminingi ephumayo (imvamisa imigqa ephumayo emi-4 kuye kweyisi-6). Kuye ngezidingo ezahlukene, ama-circuit breaker noma ama-switch switches angafakwa emigqeni engenayo naphumayo. Kumagridi wamandla kagesi aphakathi nendawo, iziteshi ezishintshayo zivame ukusetshenziselwa ukwamukela nokusabalalisa amandla angu-10kV, futhi zifakwe izintambo eziphakathi nendawo zokusabalalisa ezingenayo neziphumayo, kanye nemishini yokusabalalisa kabusha amandla.
Isiteshi esishintshayo siyindawo yokuphakela nokusabalalisa ugesi esetshenziselwa ukwamukela nokusabalalisa ugesi. Kumagridi wamandla kagesi aphezulu, kubizwa ngokuthi i-switchyard. Isici saso ukuthi i-voltage ezinhlangothini ezingenayo neziphumayo zokunikezwa kwamandla kuyafana, okulingana nokunwetshwa kwebha yesiteshi esincane. Iziphakeli zamandla ngokuvamile zisebenzisa izintambo zekhebula zesigaba esikhulu. Ingasetshenziselwa ukuxazulula inkinga yesikhala esilinganiselwe selayini engenayo naphumayo noma amaphaseji angenayo naphumayo anomkhawulo eziteshini ezincane, futhi idlala indima ekusekelweni kokuphakelwa kukagesi esifundeni. Isetshenziselwa ukusabalalisa nokuhlanganisa ama-currents omthwalo, ukuphazamisa imisinga ye-short-circuit kanye nama-transformer no-load currents, nokusingatha ukushaja kwemisinga yemigqa ephezulu kanye nezintambo zekhebula ebangeni elithile. Isebenza njengedivaysi yokulawula nokuvikela futhi iyisisetshenziswa esibalulekile sokushintshanisa ugesi wenethiwekhi oyi-loop kanye nokunikezwa kwamandla kagesi.
Lo mkhiqizo uthobelana namazinga asebenzayo: GB/T 11022-2020 "Izimfuneko Zobuchwepheshe Ezivamile Ze-High-Voltage Switchgear and Controlgear Standards" kanye ne-GB/T 3906-2006 "3.6kV kuya ku-40.5kV AC Metal-Enclosed Switchgear kanye neleveli yokuvikela ye-IP3", enezinga lokuvikela le-IP3
