Unit nokucima (CRU): iintlobo, iimpawu, isikhundla

Eli nqaku liza kunika ingcaciso malunga sokuvula nokucima epheleleyo. iimpawu zobugcisa zabo, iintlobo kunye kuqeshwa iza kunikwa.

scope

unit nokucima (CRU) - isixhobo equka iibhodi, leyo ibandakanywa ekwakhiweni:

• oomatshini ukuqala kunye nolawulo izixhobo zitya amandla-;
• isixhobo wokukhuselwa;
• kuqinisa device;

Njengoko ngokunjalo namanye amacandelo ungayikhetha, ndawonye yaye ilungele ukusetyenziswa.

Eyona njongo ephambili ukufumana kunye nokusasazwa umbane networks ontlantlu-ntathu kunye rhoqo yokusebenza-50 Hz kunye ombane kwama 1000 V.

unit nokucima (CRU) yahlulwe iintlobo ezimbini, ufakelo ngaphandle kunye nezo ziphuma ngaphakathi. Kuba izityalo ezisendlwini ezibekwe okanye kweso sakhiwo. izixhobo ezinjalo Abizelwa ndawonye busbar. Xa esetyenziselwa yombane yokusebenza ngasentla 35 kV basebenzisa uthungelwano bodwa komoya 110 kV ukwambathisa zokwambathisa igesi.

Njengomgaqo, ekusebenziseni isixhobo sokuvula nokucima eliphezulu-ombane ezincamathelayo mihla njengomkhuseli kunye isixhobo isenza, kodwa kukho izityalo lixesha kakhulu ukuba zifakelwe itshintshela ioli.

nekhabhathi Distribution, isixhobo sokuvula nokucima YE 6 zenziwa ukusetyenziswa yaphandle kwaye yahlulwe iindidi ezimbini yokusebenza: thaca, apho zonke iindawo kunye namacandelo njo nebhodi okhethekileyo, nezinto zokubhala, apho onke amalungu kunye namacandelo esifakelwa ubomi inkonzo ende.

Ukufakelwa ukufakwa ngaphandle

ufakelo nokucima ngaphandle kufuneka zilungiselele ibandla, ngoko kuqala kwiinto zonke Isisekelo. Iiseli uthuthe ifomu zigcwele phambi zonke izixhobo zibekiwe. Emva koko sibuya kunye netroli thaca ngaphandle kwezindlu apho sokuvula nokucima ifakiwe. Uhlele iseli ngokwesicwangciso. Ufakelo luqala ngokugqithileyo. Kwakuba kutshekishiwe ufakelo olululo kwikhabhinethi, isethi elandelayo. Kubalulekile ukuba iiseli akunyanzelekanga ukuba kuma kwi-engile.

Kuba imigca phezulu izibiyeli ezifuna uphahla efakiweyo. Kuyimfuneko kwakhona ukucwangcisa zokukhanya lendawo kufuphi kwiseli nganye. Intambo High-ombane nge yokuyeka umgca nokucima zimiliselwe ngeziphumo emnyango elingasemva lwekhabhinethi. Emva koko switchgears ukulungele ufakelo yangaphandle ukusebenza.

design

switchgears kubalwa (KRU) 6/10 ombane kV kufuneka siqinisekise ukusebenza okuqhelekileyo zonke izinto enyusiweyo kuyo. KRU efanayo ukubonakala kwisisele esikhulu sentsimbi, isixhobo sokuvula nokucima ngaphakathi apho ziyaxhonywa, ukhuseleko kunye nezixhobo abancedisayo. Uqweqwe engaphandle yeseli edalwe sheets intsimbi, ukuba yenziwe ukwandisa amandla zokusebenza kunye nokukhuseleka okuchasene ngoku elifutshane ukujikeleza nezinye izixhobo ekufuphi nalapho.

Distribution nekhabhathi, isixhobo sokuvula nokucima YE 6 mayixhotyiswe zokufudumeza lasekuhlaleni ezizodwa, apho izixhobo zangoku-umlinganiselo ukusebenza ebusika.

Ukucacisa nokusebenzisa isakhono

unit nokucima (CRU) 10 kV zinedatha ngama zilandelayo:

• ubonelelo yokusebenza ombane - 6, 10, 35, 110 kW;
• umgca yokusebenza industrial frequency - 50 Hz;
• Yangoku - 630 A;
• nokukhubeka yangoku - 12.5, 20, 25, 35, 40 ka;
• ukwambathisa - umoya;
• chwetheza wesekethe - cleaner;
• chwetheza transformer yangoku - ukutyhala-6;
• chwetheza amandla transformer - Xhosa-25;
• Uhlobo Drive - electric.

Lokumelana nokucima yesekethe kumiselwa ngokusekelwe kwi parameters kwezixhobo ukuba yakhiwe ibe isixhobo yotshintsho ekhwele kuyo ukuqhuba. izixhobo Ukutshintshela, nto leyo ifakwe kwi sokuvula nokucima, kufuneka ngokwesiqhelo isebenze wokuwalayisha rated kwaye ukumelana umjikelo uvavanyo ekuqhambukeni ngoku ophezulu, nto leyo zicwangciswa iinkcukacha yezixhobo zangaphakathi.

Ilungu slider kunye neqondo lokhuselo

element Cyber apho izixhobo ziguquka, enokusasazwa zombini ngesandla kwaye zoomatshini. Ngokwenza njalo, lo inqwelo kufuneka kudlule endleleni elikhulu enamathela kuba sele kakhulu bubunzima obuninzi.

Zonke nekhabhathi nokucima kufuneka ukuba apholile ukusebenza kwaye ziyilelwe ufakelo intuthuzelo, ukulungiswa kunye ukukhutshwa kwezinto ezonakeleyo. Kuninzi nekhabhathi nokucima ngexesha netroli sliding noqengqo iiseli indawo yokusebenza Ekungeneni ukuba abafowunelwa esiqingqiweyo se-wesekethe omkhulu disconnector ukutshixa nemivalo ezizodwa.

Kuxhomekeka isicelo, ukufakelwa unokuba yohlobo ezahlukeneyo yokusebenza. CRU kufuneka athobele amandla eclectic kwaye zomatshini lwezakhiwo, ubushushu kunye nokumelana neemeko ndlongondlongo yokusebenza. Crewe Category yokuhlala:

• V3 - yenzelwe ukusebenza kwiindawo ngomoya kwegazi zendalo;
• V4 - eyenzelwe amagumbi sezulu ngumntu.

Uyilo nokucima kukunika uzinzo ngexesha intlokoma ukuba zenzeke ngexesha ziguquka ngaphakathi nangaphandle itshintshela eliphezulu-ombane, kwakunye xa uhambisa le yunithi. Kulo mzekelo, zonke izixhobo kufuneka ukusebenza, kunye nokukhuselwa relay kwenzeke phakathi ukusebenza ngamaxabiso engephi.

Isixhobo sokuvula nokucima nga kuveliswa ukulungiselela iimeko ezahlukeneyo zemozulu nokusetyenziswa ukufudumeza wengingqi okanye ukupholisa.

ukuxhaphaza

Xa usebenza ixesha imfuneko nokucima ukuba aququzelele uhlolo yobugcisa kunye nokugcinwa kwezixhobo, nto leyo ibekwa esiseleni, ngokunjalo imibuzo.

Kweliso umsebenzi izixhobo inxaxheba zombane umsebenzi okanye abasebenzi abo asebenza ufakelo. Ngokutsho neemfuneko zokhuseleko ngoku, ukuba basebenze kunye Ufakelo lombane akuvumelekanga umntu omnye, ngoko xa usebenza KRU kufuneka ubuncinane ezimbini.

Abasebenzi abandakanyeke wokulungisa kufakelo kufuneka aqeqeshwe kwaye abe nokunyamezela band alithe gangqa IV, kananjalo kufuneka ukuba ukwazi izixhobo leyo ebandleni sokuvula nokucima, kunye nokubonelela iindlela zombane ukusebenza iindawo.

Ukufakelwa kunye ombane yokusebenza ka 35 kV

Nokucima umbane series BM-4 zisetyenziswa ukugqithisa amandla networks ontlantlu-ntathu ne-mbane zoshishino nezihlandlo 50 Hz kunye yokusebenza lombane 35 kV.

iseli nokucima i isakhiwo alekwe sheets intsimbi Isefu apho aba yi weld okanye rivet. Ngaphakathi enyusiweyo itshintshela eliphezulu-ombane, abaguquli ombane, isixhobo sokuvula nokucima, lezixhobo kunye isolator.

isixhobo sokuvula nokucima enjalo eyenzelwe inkonzo endlela-mbini. Xa efakwe kwi izityalo ezincinane-ubungakanani ukuvelisa inkonzo KRU-ndlela iguqulwe kancinane. Ukugcina ubushushu iiseli, kukho amakhethini. Kwakhona ukukhululeka uxinzelelo, leyo zingavela kwimeko iindlela zokusebenza yonxunguphalo okanye imisinga amadlala ukuphazamisana valve efakwe kophahla weseli.

uphawu izixhobo K-63

uphawu nokucima K-63 senziwe liqumrhu metal ubeka zigxunyekwe izixhaso, ngaphakathi leyo a kukhuseleko sokuvula nokucima kunye sombane izixhobo yonke. Isixhobo sokuvula nokucima uhlobo nokucima K-63 kwakunye nabanye, zenzelwe ukugqithisa nokusasazwa yangoku yombane networks ontlantlu-ntathu kunye rhoqo mveliso we-50 Hz kunye ombane yokusebenza 6 kV.

A feature of KRU K-63 kukuba zingasetyenziswa njenge isixhobo sombane. The main izixhobo utshintshe nje K-63 ziphezulu-current sokuyivula BB / IFONI usebenzisa baphinde electromechanical okanye MPD.

Iiseli ze K-63 zenzelwe ukuba kuzo izakhiwo, kwaye sombane kungenziwa akhiwe phandle. K-63 ibandla kunye nenkqubo busbar eyodwa, apho umbane ukudla eliphezulu-ombane entry iseli nokucima ukuba acwangcise phezu kwendlu.

Iyunithi K-594 brand: isidima

Isixhobo sokuvula nokucima KRU uphawu K-594, njengazo zonke setup ngasentla, sebenzisa i lombane 6-10 iinethiwekhi kV kunye yokusebenza rhoqo 50 Hz.

Njengomgaqo, KRU K-594 zisetyenziswa sezitishana, izityalo amandla, izibonelelo zezolimo kunye noololiwe. Isixhobo sokuvula nokucima ibandla KRU-594, ixabiso elandelwayo exhomekeke umthengisi kunye nokuthengwa kummandla, ogqibeleleyo loqhakamshelwano Iimoto ophezulu ombane kunye nezinye noomatshini sombane. Izinto eziluncedo eziphambili nokucima zezi:

• Zonke actuators zombane ndawonye kwisisele owodwa kwaye kugqitywe kwi-mveliso;
• It kwandisa ukhuseleko isityalo ngokwayo, kwakunye nabasebenzi abasebenza;
• zonke izinto ezininzi ezinzima zifakwe kwi thaca enqwelweni, leyo kunciphisa ukuntsonkotha umsebenzi nokugcinwa kwezixhobo;
• Iiseli KRU azikho enkulu, ngoko ukugcina kakhulu nesithuba gumbi.

unit nokucima (CRU) K-594 series kufuneka iinkcukacha ezinokuba ukutshintsha kwimeko ukwandisa okanye ukunciphisa indices wesiqhelo ibalwe labathengi, apho ziza kuqhagamshelaniswa nokucima.

isiphelo

KRU - yindlela ethembekileyo ukudibanisa abathengi ezithembeke kakhulu kwaye kulula ukuyisebenzisa, kunye nokugcinwa lula nokulungiswa. Baye wathola udumo lwabo kwimarike yehlabathi nje isixhobo zokuhambisa umbane oluthembekileyo.
