Switchgear iyunithi (CRU): izinhlobo, izici, isiqu

Lesi sihloko sizosisiza ukuhlinzeka ngolwazi mayelana switchgear ephelele. izici lobuchwepheshe zabo, izinhlobo kanye nokuqokwa uzonikezwa.

Ububanzi

Switchgear iyunithi (CRU) - idivayisi ehlanganisa amabhodi, okuhlanganiswayo lichaza ekwakheni:

• imishini uqale namandla okudla imishini ukuphathwa;
• idivayisi Ukuvikelwa;
• ukunqanda idivayisi;

Kanye nezinye izingxenye ozikhethela, sibuthene futhi isilungele ukusetshenziswa.

Inhloso eyinhloko ukuthola nokwenza eminye yokusabalalisa ugesi e ezintathu okhombisa amanethiwekhi nge imvamisa yokusebenza 50 Hz futhi zinamandla ka kuka-1000 i-V

Switchgear iyunithi (CRU) ihlukaniswe izinhlobo ezimbili, ukufakwa zangaphakathi nezangaphandle. Ukuze izitshalo zasendlini ezibekwe noma esakhiweni. Amadivayisi anjalo ababuthelwa ne busbar. Lapho esetshenziselwa yokusebenza voltages ngenhla 35 kV isicelo emoyeni ngabodwa amanethiwekhi 110 kV ukwahlukanisa kuvikela igesi.

Njengomthetho, e yesimanje switchgear ukusetshenziswa ephezulu voltage cleaner ukushintsha njengoba Ukuvikelwa nedivayisi ukushintsha, kodwa kukhona izitshalo akusebenzi ngaphezulu ukuthi basuke efakwe ukushintshwa uwoyela.

Distribution amakhabethe, switchgear RN 6 enzelwa nokusetshenziswa ongaphandle futhi zihlukaniswe izinhlobo ezimbili ukusebenza: sikhipha, lapho zonke izingxenye futhi izingxenye njó ibhodi ekhethekile, futhi umile, lapho zonke izingxenye futhi ezifakiwe for ukuphila isikhathi eside.

Ukufakwa ukufakwa ongaphandle

Switchgear ukufakwa ongaphandle kufanele lilungele umhlangano, ngakho kuqala kunazo zonke kwesisekelo. Amaseli ukuhambisa ngefomu elinezinto ngaphambi wonke amadivaysi asethwe. Ngemva kwalokho angakathululwa trolley sikhipha izindlu lapho switchgear ifakiwe. Setha iseli ilungiselelo ngokuvumelana uhlelo. Ukufakwa iqala ngokwedlulele. Uma kuqinisekisiwe ukufakwa lesifanele iKhabhinethi, isinyathelo esilandelayo. Kubalulekile ukuthi amaseli akudingeki ukuma engela.

Ukuze imigqa phezulu ophahleni obandayo kubakaki ezifakiwe. Kuyadingeka ukusetha ukukhanyisa wendawo eduze ingqamuzana ngalinye. High-voltage ikhebula nge umugqa Ukunqanyulwa kwe-switchgear zigxilé okutholakele umnyango ezingemuva iKhabhinethi. Ngemva kwalokho switchgears ukufakwa ongaphandle isilungele ukusebenza.

design

switchgears ibalwa (KRU) 6/10 kV voltage kumelwe ukuqinisekisa ukusebenza evamile lwazo zonke izinto ukukhwezwa therein. KRU efanayo ngokubukeka enkulu steel cell, switchgear ngaphakathi zazo ogibele, ukuvikelwa kanye namadivayisi asizayo. Ikhava elingaphandle iseli idaliwe kusuka amashidi steel esenziwe ukwandisa amandla kwesakhiwo isivikelo isekhethi samanje namanye amadivayisi eliseduze.

Distribution amakhabethe, switchgear RN 6 ifakwe Ukushisa elikhethekile lendawo, lapho amadivayisi wamanje-yokulinganisa uvame ukusebenza ebusika.

Imininingwane ukushintsha umthamo

Switchgear iyunithi (CRU) 10 kV has idatha elandelayo okuzisholo:

• yokusebenza supply voltage - 6, 10, 35, 110 kW;
• zezimboni yokusebenza umugqa imvamisa - 50 Hz;
• Ukusebenza yamanje - 630 A;
• ezithothene wamanje - 12.5, 20, 25, 35, 40 KA;
• ukwahlukanisa - emoyeni;
• thayipha wesifunda - a cleaner;
• thayipha transformer wamanje - baphokophelele-6;
• thayipha amandla transformer - TM-25;
• Uhlobo Drive - kagesi.

I ukumelana wesifunda switchgear kunqunywa isekelwe kwemigomo imishini ukuthi yakhiwe ibe idivayisi inkinobho aboshelwe ke ukushayela. imishini Ukushintsha ama, okuyinto efakwe kule switchgear, ngokuvamile kufanele sisebenze ngesikalo umthwalo owalinganisile ukumelana umjikelezo isivivinyo nganoma okusezingeni eliphezulu kuphulwa samanje, asethwe e ezibekiweko amadivayisi angaphakathi.

Ilunga slider bese degree of Ukuvikelwa

elementi retractable enikezwe imishini usuke, angadluliselwa kokubili ngesandla bese athutha. Ngokwenza kanjalo, inqola Uzodlula indlela i ngisho enamathela njengoba has ngempela eziningi isisindo.

Zonke amakhabethe switchgear kudingeka ngikhululekile phakathi ukusebenza futhi enzelwe ukufakwa induduzo, ukulungisa kanye esikhundleni izingxenye. Ngo iningi switchgear amakhabethe ngesikhathi inqola ngokuhambisa sikhipha amangqamuzana isikhundla zokusebenza ukuvuleka othintana elimisiwe circuit main disconnector ukukhiya amafasitela ekhethekile.

Kuye isicelo, ukufakwa kungaba uhlobo oluhlukile ukusebenza. CRU kufanele uhambisane amandla eclectic futhi mechanical kwesakhiwo, ukwahlukanisa kanye ukumelana nezimo yokusebenza nolaka. Isigaba yokuhlala Crewe:

• V3 - yakhelwe ukusebenza ezindaweni zemvelo air kwegazi;
• V4 - eyenzelwe amakamelo ne sezulu yokufakelwa.

Umklamo switchgear ukunikeza ukuzinza phakathi kunyakaza ezenzeka phakathi usuke ngaphakathi nangaphandle kwe-ephezulu voltage ukushintshwa, kanye nalapho umuntu eshintshashintsha ukuhamba iyunithi. Kulokhu, wonke amadivayisi kufanele ukusebenza, kanye nokuvikelwa edluliselwe kungenzeki ngesikhathi ukusebenza ngamazinga bokuzisholo.

Switchgear kungenziwa ekhiqizwa izimo ezahlukene zezulu nokusetshenziswa Ukushisa zendawo noma indlu.

ukuxhashazwa

Lapho eqhuba switchgear isidingo isikhathi ukuhlela wokuhlola lobuchwepheshe kanye nokugcinwa imishini, okuyinto ibekwe esitokisini, kanye inkinga.

Ukugada umsebenzi imishini abathintekayo imisebenzi Electricians noma isibalo sabasebenzi ababa izakhi ukufakwa. Ngokusho izidingo zokuphepha wamanje, ukusebenza ukufaka kagesi ayivunyelwe oyedwa, ngakho lapho esebenza KRU kudingeka okungenani ezimbili.

Abasebenzi abenza ukufakwa ukulungisa kumelwe sibe abaqeqeshwe futhi ube band ukubekezelelana hhayi ngaphansana IV, futhi udinga ukwazi mayelana imishini okungukuthi ebandleni switchgear, futhi ukunikeza izindlela kagesi ukusebenza izingxenye.

Ukufakwa nge voltage yokusebenza 35 kV

Switchgear high voltage uchungechunge BM-4 asetshenziselwa amandla ukudluliswa e ezintathu okhombisa amanethiwekhi ne amapayipi ezimbonini imvamisa 50 Hz kanye voltage yokusebenza 35 kV.

iseli switchgear isakhiwo Unamekwe nge lashukumisa amashidi steel zazo wajoyina ngumuntu weld noma isipikili. Ngaphakathi ukukhwezwa ephezulu voltage ukushintshwa, voltage transformers, switchgear, instrumentation kanye isolator.

switchgear okunjalo eyenzelwe ezimbili ngendlela inkonzo. Lapho ukufakwa izitshalo ezincane obujwayelekile esikhiqiza Ushintshe KRU-indlela inkonzo. Ukuze silondoloze lokushisa kumaseli, kukhona amakhethini. Futhi ngicele impumuzo ingcindezi, okungase avele uma eziphuthumayo ukusebenza izindlela noma iphutha imisinga ukubhidliza valve efakwe ophahleni cell.

Iinsetjenziswa uphawu K-63

Switchgear uphawu K-63 Yenziwa kusukela umzimba wensimbi isandla fixed kuya ezisekelweni, ngaphakathi okuyinto wonke Avikelayo switchgear kanye transformer imishini. Switchgear uhlobo switchgear K-63 kanye nabanye, zenzelwe kutfunyelwa nekusatjalaliswa kagesi e ezintathu okhombisa amanethiwekhi kanye nokuvama yezimboni 50 Hz futhi nge voltage yokusebenza 6 kV.

Isici esivelele sesimiso KRU K-63 ukuthi ingasetshenziswa njengendlela idivayisi transformer. The main usuke amadivaysi K-63 ziphezulu-zamanje sekuqalile BB / UCINGO usebenzisa udlulisela electromechanical noma MPD.

Amaseli we-K-63 zenzelwe ukufakwa ngendlela izakhiwo, kanye transformer kungenziwa akhiwe ngaphandle. K-63 libuthene nge busbar uhlelo olulodwa, lapho ugesi sidla ngokusebenzisa ephezulu voltage switchgear cell zokungena kuleso ahlelwe ophahleni.

Iyunithi K-594 brand: isithunzi

Switchgear KRU uphawu K-594, njengazo zonke isethaphu ngenhla, sisebenzise voltage ka 6-10 kV amanethiwekhi kanye imvamisa yokusebenza 50 Hz.

Njengomthetho, KRU K-594 asetshenziswa ezincane, izitshalo amandla, izindawo zokulima nojantshi. Switchgear inhlangano KRU-594, intengo zazo kuncike komphakeli ukuthengwa esifundeni, ephelele yokuxhuma ephezulu voltage izinjini nezinye imishini kagesi. Izinzuzo esemqoka switchgear yilezi:

• Zonke actuators kagesi ababuthelwa kuseli eyodwa futhi ligcwaliswe efektri;
• It kwandisa ukuphepha isitshalo uqobo, kanye kubasebenzi abasebenza;
• zonke izici eziyinkimbinkimbi kakhulu ogibele sikhipha inqola, esehlisa yinkimbinkimbi umsebenzi ekugcineni imishini;
• KRU amaseli akuzona okukhulu, ngakho kakhulu wonge isikhala egumbini.

Switchgear iyunithi (CRU) K-594 chungechunge ziye Ukucaciswa ukuthi zingashintsha uma ngokwandisa noma ukunciphisa ibalwa indices ngokulinganisa of abathengi, okuzokwenza ixhunywe switchgear.

isiphetho

KRU - kuyindlela okuthembekile ukuxhuma abathengi njengoba enokwethenjelwa kakhulu futhi kulula ukuyisebenzisa, kanye nokugcinwa lula futhi ukulungisa. Baye wathola udumo lwawo emakethe emhlabeni njengomuntu onokwethenjelwa imishini amandla transmission.
