Isishwankathelo:Inethiwekhi ethembekileyo yokusasazwa kwe-voltage ephakathi ixhomekeke kuphazamiseko olukhawulezayo lwempazamo, ukugquma okuthembekileyo, kunye nokusebenza kwangaphandle okuzinzileyo. I33kV Ipali enye yeSaphuli seSekethe yaNgaphandleukusukaAnqiangyenzelwe ukuhanjiswa okuphezulu kwezicelo apho ulwakhiwo oluxhonywe kwipali edibeneyo, ukutshintshwa ngokukhawuleza, umthamo omkhulu wokuqhekeka, kunye nokumelana nokusingqongileyo kubalulekile. Ngomatshini wokusebenza wemagnethi osisigxina, ulawulo olukrelekrele, kunye noyilo oluluqilima lokugquma, lubonelela ngesisombululo esisebenzayo kwizinto eziluncedo, izitishi, kunye neenkqubo zokuhambisa amandla kwimizi-mveliso.
I-33kV I-Single Pole Outdoor Circuit Breaker sisixhobo esiphakathi sokutshintsha kunye nokukhusela isixhobo esilungiselelwe iinkqubo zokusasaza amandla angaphandle. Indima yayo ephambili kukulawula iisekethe zombane phantsi kweemeko eziqhelekileyo zokusebenza kunye nokuphazamisa iimeko ezingaqhelekanga ezifana nokugqithiswa, i-fault currents, kunye neesekethe ezimfutshane.
Ngokungafaniyo nesixhobo sokutshintsha esiqhelekileyo sangaphakathi, isitshixo sesekethe esixhonywe ngaphandle kufuneka simelane nokutshintsha kwemozulu, ukuguquguquka kobushushu, umoya, ungcoliseko, kunye nolunye uxinzelelo lokusingqongileyo. Ke ngoko, ukwakheka kwayo ngoomatshini, inkqubo yokugquma, indlela yokusebenza, kunye noyilo lwendawo ebiyelweyo zonke zinegalelo ekuthembekeni kwexesha elide.
Isisombululo se-Anqiang senziwe malunga nokucwangciswa kwe-compact single-pole kunye nokubandakanya umatshini wokusebenza wamagnetic osisigxina, amacandelo aphezulu okukhusela, kunye nomlawuli ohlakaniphile. Imveliso yenzelwe izicelo apho ukusebenza ngokukhawuleza, ukuphazamiseka kwempazamo ethembekileyo, kunye nokunciphisa iimfuno zokugcina zibalulekile.
Uthungelwano lwe-overhead ye-voltage ephakathi lugubungela imigama emide kwaye kaninzi lusebenza kwindawo etyhilekileyo. Isiphoso kwicandelo elinye lothungelwano sinokuchaphazela abaguquli abasezantsi, i-feeders, izixhobo zoshishino, kunye nabathengi ukuba aluphazamiseki ngokukhawuleza.
I-33kV ekhethiweyo ngokufanelekileyo i-circuit breaker yangaphandle inceda ukujongana nale mingcipheko ngokubonelela ngokutshintsha okulawulwayo kunye nokuphazamiseka ngokukhawuleza kweempazamo. Umsebenzi wayo wokukhusela unokuncedisa ukukhawulela ixesha elingaqhelekanga langoku kunye nokunciphisa amathuba okuba umonakalo usasazeka kwinethiwekhi yokusabalalisa.
Iinzuzo eziphambili ziquka:
Xa uvavanya i-medium-voltage outdoor breaker, abathengi kufuneka baqwalasele ngaphezu kombane wayo oqhelekileyo. Ukuphazamisa amandla, ukusebenza kokugquma, isantya sokusebenza, ubomi boomatshini, ukufaneleka kokusingqongileyo, kunye neemfuno zolawulo zonke zinefuthe lokuba isixhobo sifanelekile na kwiprojekthi ethile.
Ukucwangciswa kwe-single-pole yangaphandle ifanelekile kuthungelwano lokusasazwa kwe-overhead apho izixhobo zifakwe kwisibonda soncedo okanye ukuxhasa isakhiwo sensimbi. Ukulungelelaniswa kwayo kunokunceda ukwandisa indawo yokufakela ngelixa ugcina ukukhutshwa kombane okuyimfuneko.
Indlela yokusebenza yemagnethi esisigxina yenzelwe ukubonelela ngokusebenza kokutshintsha okukhawulezileyo nokuzinza. I-voltage yolawulo echaziweyo yi-DC220V, ngelixa iimpawu zokuvula kunye nokuvala zenzelwe ukusebenza okuphindaphindiweyo.
Izixhobo zangaphandle ze-medium-voltage kufuneka zigcine ingqibelelo yokufakelwa phantsi kombane kunye noxinzelelo lokusingqongileyo. Lo mzekelo ubonelela ngomzuzu we-1 we-power-frequency resistant voltage ye-80/95kV kunye nombane wokunyanzeliswa kombane wokumelana nombane we-185kV, ngokwedatha yobugcisa epapashiweyo.
I-breaker ifumaneka nge-rated short-circuit breaking currents ye-20kA, 25kA, kunye ne-31.5kA. Olu luhlu luvumela iinjineli ukuba zitshatise i-breaker kunye neemfuno ezahlukeneyo zomgangatho we-network fault-level.
Umlawuli okrelekrele unokuxhasa ukutshintshwa okulungelelanisiweyo kunye nemisebenzi yokukhusela. Kuthungelwano olungaphezulu, ukuvala ngokuzenzekelayo kunokunceda ukubuyisela inkonzo emva kweempazamo zexeshana xa iskimu sokhuseleko kunye noyilo lwenethiwekhi luyivumela.
Iinkcukacha zobugcisa kufuneka zihlale zitshekishwa ngokuthelekisa noyilo lweprojekthi oluyinyani, inqanaba lesiphako senkqubo, ulungelelwaniso lokugquma, indawo yofakelo, kunye nemigangatho esebenzayo. Le theyibhile ilandelayo ishwankathela inqununu epapashiweyo iiparamitha zale mveliso.

Ezi nkcukacha zibonisa ukuba kutheni olu hlobo lwe-breaker lunokuthi luthathelwe ingqalelo kwiiprojekthi zokusabalalisa i-voltage medium-voltage apho amandla aphezulu e-insulation, ukuphazamiseka kokuphazamiseka, kunye nokusebenza ngokuphindaphindiweyo komatshini kuyadingeka.
I-33kV Single Pole Outdoor Circuit Breaker ifaneleke ngokukodwa kwiindawo zokuhambisa ngaphezulu kwe-voltage. Ulwakhiwo lwalo lwangaphandle kunye noqwalaselo oluxhonywe kwipali lwenza ukuba lube luncedo kwiinkqubo ezahlukeneyo zeziseko zombane.
Kumniki-nkonzo waseTshayina okanye uvandlakanyo lomenzi, abathengi kufuneka bavavanye kungekuphela nje iinkcukacha zemveliso kodwa kunye nenkxaso yobunjineli, amandla okwenza ngokwezifiso, umgangatho wemveliso, iinkqubo zovavanyo, amandla okuhambisa, kunye nenkonzo yasemva kokuthengisa.
Ufakelo oluchanekileyo luyimfuneko ekusebenzeni ngokukhuselekileyo kwanoma yimuphi umqhekezi wesiphaluka ophakathi. Ipali exhasayo okanye isakhiwo sentsimbi kufuneka sinikeze ukuzinza okwaneleyo komatshini, ngelixa ukuxutywa komhlaba kunye nombane kufuneka kuhambelane neemfuno zobunjineli beprojekthi.
Inkqubo eqhelekileyo yokugunyazisa kufuneka ibandakanye:
Ukufakela kunye nokugunyaziswa kufuneka kwenziwe ngabasebenzi bombane abafanelekileyo ngokulandela amaxwebhu omenzi kunye neemfuno ezisebenzayo zokhuseleko lwendawo.
Ukukhetha i-33kV i-breaker yangaphandle kufuneka iqale ngeempawu zombane zenethiwekhi kunokuba ixabiso lodwa. Isixhobo esifanelekileyo ngokobuchwepheshe kufuneka sihambelane nombane wenkqubo, okwangoku, inqanaba lempazamo, iimfuno zokugquma, inkqubo yolawulo, kunye neemeko zokusingqongileyo.
Ngaphambi kokuthenga, qwalasela oku kulandelayo:
Iimeko zokusebenza ezipapashiweyo zale modeli ziquka ubushushu obuphakathi kwe -30 ° C ukuya + 60 ° C, ukuphakama ukuya kwi-2,000 yeemitha, isantya somoya ukuya kwi-34 m / s, kunye ne-pollution degree IV. Ubushushu bokugcina buchazwa ukusuka kwi -40°C ukuya +85°C.
Umsebenzi wayo ophambili kukulawula nokuphazamisa iisekethe zombane kwiinkqubo zokusasazwa kwe-voltage ephakathi. Ngexesha leemeko ezingaqhelekanga, inceda ukwahlula imisinga yempazamo kunye nokukhusela izixhobo zombane ezisezantsi.
Ewe. Imveliso yenzelwe ngokukodwa izicelo ezifakwe kwipali yangaphandle kwaye yenzelwe iimeko zokusingqongileyo kubandakanya ukuhluka kobushushu, umoya, kunye namanqanaba aphezulu ongcoliseko.
Uluhlu olupapashiweyo lweenkcukacha zobugcisa lulinganiswe ukhetho lwangoku lwe-630A kunye ne-1250A. Ukhetho olufanelekileyo luxhomekeke kwiimpawu zombane kunye neemfuno zomthwalo wenkqubo yokusabalalisa.
Iinketho ezidwelisiweyo zokwaphuka kwesekethi emfutshane yi-20kA, 25kA, kunye ne-31.5kA. Iinjineli kufuneka zikhethe ukulinganisa okufanelekileyo ngokwenqanaba lempazamo elibaliweyo lofakelo.
Imveliso yenzelwe ukusebenza ngokukhawuleza kunye nokukwazi ukuvala ngokuzenzekelayo, okunokuba luncedo kwiinethiwekhi ezifanelekileyo zokusasazwa kwe-overhead apho iimpazamo zexeshana ziqhelekileyo.
Ewe. U-Anqiang uthi unokwenza iiyunithi zibe ngokwezifiso zokulinganisa amandla ombane ngokweemfuno zomsebenzisi, ukwenza ukubonisana kobugcisa kube luncedo kwiiprojekthi ezinombane ongekho semgangathweni okanye wofakelo.
I-breaker circuit yangaphandle ethembekileyo yinto ebalulekileyo yenethiwekhi yokusabalalisa i-voltage ekhuselekileyo kunye neyomelele. I33kV Ipali enye yeSaphuli seSekethe yaNgaphandleidibanisa i-compact pole-mounted configuration kunye nokusebenza okuphezulu kwe-insulation, iinketho ezininzi zangoku kunye nokuqhawula amandla, iimpawu zokusebenza ezikhawulezayo, i-magnetic mechanism esisigxina, kunye nolawulo oluhlakaniphile. Ezi mpawu zenza ukuba zilungele iigridi eziluncedo, izitishi, iinkqubo zokusasaza kwimizi-mveliso, kunye nezinye izicelo zangaphandle ze-medium-voltage.
Kubathengi abathelekisa umenzi okanye umthengisi waseTshayina, ukuhambelana kobugcisa kufuneka kuhlale kuphambili kuqala. Vavanya amandla ombane alinganisiweyo, angoku, amandla esekethe esifutshane, ukusebenza kokugquma, iimeko zokusingqongileyo, iimfuno zofakelo, ukuhambelana kolawulo, kunye neemfuno zokwenza ngokwezifiso phambi kokubeka iodolo. Ukuba ucwangcisa iprojekthi entsha yokuhambisa okanye uphucula inkqubo ekhoyo yokutshintsha ngaphandle,Qhagamshelana nathiukuxoxa ngeemfuno zakho zobugcisa kunye nokuchonga isisombululo esifanelekileyo se-33kV se-circuit breaker kwisicelo sakho.
