Isifinyezo:Inethiwekhi ethembekile yokusabalalisa i-medium-voltage incike ekuphazanyisweni kwephutha okusheshayo, ukwahlukanisa okuthembekile, nokusebenza kwangaphandle okuzinzile. I33kV I-Single Pole Outdoor Circuit BreakerkusukaAnqiangyakhelwe izinhlelo zokusebenza zokusabalalisa phezulu lapho ukwakhiwa okugxunyekwe esigxotsheni, ukushintsha ngokushesha, umthamo wokuphuka okuphezulu, kanye nokumelana nemvelo kubalulekile. Ngomshini wokusebenza kazibuthe unomphela, isilawuli esihlakaniphile, kanye nedizayini yokufaka eqinile, inikeza isisombululo esisebenzayo sezinsiza, iziteshi ezingaphansi, nezinhlelo zokusabalalisa amandla ezimboni.
I-33kV Single Pole Outdoor Circuit Breaker iyidivayisi eshintshwayo ene-voltage emaphakathi neklanyelwe amasistimu okusabalalisa amandla angaphezulu kwangaphandle. Indima yayo eyinhloko ukulawula amasekhethi kagesi ngaphansi kwezimo ezivamile zokusebenza kanye nokuphazamisa izimo ezingavamile ezifana nokulayishwa ngokweqile, ama-curls amaphutha, namasekhethi amafushane.
Ngokungafani ne-switchgear evamile yasendlini, i-circuit breaker yangaphandle egibele phezulu kufanele imelane nokushintsha kwesimo sezulu, ukushintshashintsha kwezinga lokushisa, umoya, ukungcola, nezinye izingcindezi zemvelo. Ngakho-ke, ukwakheka kwayo komshini, isistimu yokufaka izinto, indlela yokusebenza, kanye nokwakheka kwendawo ebiyelwe konke kunomthelela ekuthembekeni kwesikhathi eside.
Isixazululo se-Anqiang siklanyelwe ukuzungeza ukucushwa kwesigxobo esisodwa esihlangene futhi sihlanganisa indlela yokusebenza kazibuthe unomphela, izingxenye zokufakwa kwamandla aphezulu, kanye nesilawuli esihlakaniphile. Umkhiqizo uhloselwe izinhlelo zokusebenza lapho ukusebenza okusheshayo, ukuphazamiseka okuthembekile kwephutha, kanye nezidingo zokulungisa ezincishisiwe zibalulekile.
Amanethiwekhi aphezulu we-Medium-voltage amboza amabanga amade futhi avame ukusebenza ezindaweni ezisobala. Iphutha engxenyeni eyodwa yenethiwekhi ingase ithinte ama-transformer angezansi komfula, izifunzi, okokusebenza kwezimboni, namakhasimende uma kungaphazanyiswa ngokushesha.
I-33kV ye-circuit breaker ekhethwe kahle isiza ukubhekana nalezi zingozi ngokuhlinzeka ngokushintsha okulawulwayo kanye nokuphazamiseka kwamaphutha okusheshayo. Umsebenzi wayo wokuvikela ungasiza ukunciphisa ubude besikhathi samanje esingavamile futhi unciphise amathuba okulimala asakazeka ngenethiwekhi yokusabalalisa.
Izinzuzo ezibalulekile zifaka:
Lapho uhlola i-medium-voltage outdoor breaker, abathengi kufanele bacabangele okungaphezu kwamandla kagesi ayo okuzisholo wona. Amandla okuphazamisa, ukusebenza kokushisa, isivinini sokusebenza, impilo yokusebenza, ukufaneleka kwemvelo, kanye nezimfuneko zokulawula konke kuthonya ukuthi okokusebenza kuyifanele yini iphrojekthi ethile.
Ukucushwa kwangaphandle kwe-single-pole kulungele amanethiwekhi okusabalalisa phezulu lapho okokusebenza kufakwe esigxotsheni sosizo noma isakhiwo sensimbi esisekelayo. Ukuhlelwa kwayo okuhlangene kungasiza ukwandisa indawo yokufaka ngenkathi kugcinwa izindawo ezidingekayo zikagesi.
Umshini wokusebenza kazibuthe unomphela uklanyelwe ukuhlinzeka ngokusebenza kokushintsha okusheshayo nokuzinzile. I-voltage yokulawula eshiwo yi-DC220V, kuyilapho izici zokuvula nokuvala zenzelwe ukusebenza okuphindaphindwayo.
Imishini yangaphandle ene-medium-voltage kumele igcine ubuqotho be-insulation ngaphansi kwengcindezi kagesi neyemvelo. Le modeli ihlinzeka ngomzuzu ongu-1 wefrikhwensi yamandla ukumelana nomthamo ongu-80/95kV kanye nomfutho wombani umelane nogesi ongu-185kV, ngokuya ngedatha yobuchwepheshe eshicilelwe.
I-breaker iyatholakala ngamaza okuphulwa kwesekethe emfishane elinganiselwe engu-20kA, 25kA, kanye no-31.5kA. Lobu bubanzi buvumela onjiniyela ukuthi bafanise isinqamuli nezidingo ezihlukile zeleveli yephutha lenethiwekhi.
Isilawuli esihlakaniphile singasekela ukushintsha okuhlanganisiwe nemisebenzi yokuvikela. Kumanethiwekhi aphezulu, ukuvala kabusha okuzenzakalelayo kungasiza futhi ukubuyisela isevisi ngemva kwamaphutha esikhashana uma isikimu sokuvikela nomklamo wenethiwekhi kukuvumela.
Ukucaciswa kobuchwepheshe kufanele ngaso sonke isikhathi kubhekwe ngokumelene nomklamo wangempela wephrojekthi, izinga lephutha lesistimu, ukuhlanganiswa kokufakwa kwezinto, indawo yokufaka, kanye namazinga asebenzayo. Ithebula elilandelayo lifingqa amapharamitha ashicilelwe ayinhloko walo mkhiqizo.

Lezi zicaciso zibonisa ukuthi kungani lolu hlobo lwe-breaker lungacatshangelwa amaphrojekthi okusabalalisa amandla kagesi aphakathi nendawo lapho amandla aphezulu okufaka, ukuphazamiseka kwamaphutha, nokusebenza ngokuphindaphindiwe komshini kuyadingeka.
I-33kV Single Pole Outdoor Circuit Breaker ifaneleka ikakhulukazi ezindaweni zokusabalalisa phezulu kwe-voltage emaphakathi. Ukwakhiwa kwayo kwangaphandle kanye nokucushwa okubekwe ngezigxobo kukwenza kube usizo ezinhlotsheni ezihlukahlukene zengqalasizinda yamandla.
Ukuze kuhlolwe umphakeli waseChina noma umkhiqizi, abathengi akufanele bahlole imininingwane yomkhiqizo kuphela kodwa futhi bahlole nokusekelwa konjiniyela, amandla okwenza ngokwezifiso, ikhwalithi yokukhiqiza, izinqubo zokuhlola, amandla okulethwa, kanye nesevisi yangemuva kokuthengisa.
Ukufakwa okulungile kubalulekile ekusebenzeni okuphephile kwanoma iyiphi i-medium-voltage circuit breaker. Isigxobo esisekelayo noma isakhiwo sensimbi kufanele sinikeze ukuzinza okwanele kwemishini, kuyilapho ukuxhunywa komhlaba kanye nogesi kufanele kuhambisane nezidingo zobunjiniyela bephrojekthi.
Inqubo evamile yokugunyazwa kufanele ihlanganise:
Ukufaka kanye nokugunyazwa kufanele kwenziwe izisebenzi zikagesi eziqeqeshwe ngokufanelekile ngokulandela imibhalo yomkhiqizi kanye nezidingo zokuphepha zasendaweni ezisebenzayo.
Ukukhetha i-33kV yokuphula ngaphandle kufanele kuqale ngezici zikagesi zenethiwekhi esikhundleni sentengo yodwa. Idivayisi efaneleke ngokobuchwepheshe kufanele ifane nevoltheji yesistimu, yamanje, ileveli yephutha, izimfuneko zokuhlukanisa, isistimu yokulawula, nezimo zemvelo.
Ngaphambi kokuthenga, cabanga ngalokhu okulandelayo:
Izimo zokusebenza ezishicilelwe zale modeli zihlanganisa izinga lokushisa elizungezile elingu--30°C kuya ku-+60°C, ukuphakama okungafika kumamitha angu-2,000, isivinini somoya esifika ku-34 m/s, kanye ne-pollution degree IV. Izinga lokushisa lesitoreji licaciswe ukusuka ku--40°C kuya ku-+85°C.
Umsebenzi wayo oyinhloko ukulawula nokuphazamisa amasekhethi kagesi kumasistimu okusabalalisa ama-overhead ane-medium-voltage. Ngesikhathi sezimo ezingavamile, isiza ukuhlukanisa imisinga yamaphutha futhi ivikele okokusebenza kukagesi okwehla nomfula.
Yebo. Umkhiqizo uklanyelwe ngokukhethekile izinhlelo zokusebenza ezifakwe ngaphandle futhi uklanyelwe izimo zemvelo ezihlanganisa ukuhlukahluka kwezinga lokushisa, umoya, namazinga aphezulu okungcola.
Uhlu lwezicaciso zobuchwepheshe olushicilelwe lulinganise izinketho zamanje ze-630A kanye ne-1250A. Ukukhethwa okufanele kuncike ezicini zikagesi kanye nezidingo zomthwalo wesistimu yokusabalalisa.
Izinketho zamanje ezilinganiselwe zokuphulwa kwesekethe emfishane zingu-20kA, 25kA, kanye no-31.5kA. Onjiniyela kufanele bakhethe isilinganiso esifanele ngokuya ngeleveli yephutha ebaliwe yokufaka.
Umkhiqizo uklanywe ngokusebenza okusheshayo kanye nekhono lokuvala kabusha okuzenzakalelayo, okungaba yinzuzo kumanethiwekhi okusabalalisa aphezulu aphezulu lapho amaphutha esikhashana evame khona.
Yebo. I-Anqiang ithi ingakwazi ukwenza ngendlela oyifisayo amayunithi ukuze izilinganiso zamandla kagesi athile ngokwezidingo zomsebenzisi, yenze ukubonisana nobuchwepheshe kube usizo kumaphrojekthi anezidingo ezingajwayelekile zikagesi noma zokufakwa.
I-breaker circuit yangaphandle ethembekile iyingxenye ebalulekile yenethiwekhi yokusabalalisa i-medium-voltage ephephile futhi eqinile. I33kV I-Single Pole Outdoor Circuit Breakerihlanganisa ukucushwa okugxunyekwe kwesigxobo esihlangene nokusebenza kokufakwa okuphezulu, izinketho eziningi zamanje nezamandla aphukayo, izici zokusebenza ezisheshayo, umshini ozibuthe ongunaphakade, nokulawula okuhlakaniphile. Lezi zici ziyenza ifaneleke kumagridi okusetshenziswayo, iziteshi ezincane, amasistimu okusabalalisa ezimbonini, nezinye izinhlelo zokusebenza zangaphandle zamandla kagesi aphakathi nendawo.
Kubathengi abaqhathanisa nomkhiqizi noma umphakeli waseShayina, ukuhambisana kobuchwepheshe kufanele kuhlale kuyinto ehamba phambili. Linganisa ugesi olinganiselwe, wamanje, umthamo wesekethe emfishane, ukusebenza kwe-insulation, izimo zemvelo, izidingo zokufakwa, ukuhambisana kokulawula, nezidingo zokwenza ngokwezifiso ngaphambi kokufaka i-oda. Uma uhlela iphrojekthi entsha yokusabalalisa noma uthuthukisa isistimu yokushintsha yangaphandle ekhona,Xhumana nathiukuxoxa ngezidingo zakho zobuchwepheshe futhi uhlonze isisombululo esifanele se-33kV se-circuit breaker sohlelo lwakho lokusebenza.
