Isingeniso esijwayelekile
I-GHXH-12 yokuvikela imvelo igesi egqunywe indandatho yochungechunge lweyunithi eyinhloko iyisethi ephelele yamadivayisi okusabalalisa amandla we-12kV, i-AC 50Hz yezigaba ezintathu, ibha yebhasi eyodwa kanye nesistimu ehlukaniswe ibhasbha eyodwa. Umkhiqizo unezici zesakhiwo esilula, ukusebenza okuguquguqukayo, ukuxhuma okuthembekile, ukufakwa okulula, njll. Unganikeza izixazululo ezanelisayo zezobuchwepheshe ngezikhathi ezihlukahlukene zohlelo lokusebenza kanye nabasebenzisi abahlukene. Ukwamukelwa kobuchwepheshe bezinzwa kanye nobuchwepheshe bolwazi, kuhlanganiswe nokusebenza kobuchwepheshe kanye nezikimu zokumisa ezilula nezivumelana nezimo, kungahlangabezana nezidingo ezihlala zishintsha zemakethe futhi zifanele izidingo zobuhlakani begridi.
I-GHXH-12 yokuvikela imvelo igesi insulated main unit series ilungele inethiwekhi yezimboni kanye ne-civil cable ring kanye namaphrojekthi wenethiwekhi yokusabalalisa. Njengokwamukelwa nokusatshalaliswa kwamandla kagesi, kufanelekile ikakhulukazi ukusatshalaliswa kwamandla ezindaweni zokuhlala zasemadolobheni, iziteshi ezincane zesibili, iziteshi zokuvula nokuvala, amabhokisi egatsha lezintambo, iziteshi ezincane zohlobo lwamabhokisi, amabhizinisi ezimboni kanye nezimayini, izitolo ezinkulu, izikhumulo zezindiza, imigwaqo ehamba ngaphansi. , ukukhiqizwa kwamandla omoya, izinkundla , izitimela, imigudu nezinye izindawo ezisetshenziswayo.
I-GHXH-12 yokuvikela imvelo uchungechunge lweyunithi enkulu yeringi egqunywe ngegesi ihlangabezana namazinga afanele kazwelonke, amazinga emboni yamandla namanye amazinga. Ukushintsha kwayo kanye nezingxenye zikagesi eziyinhloko amamojula ahlanganisiwe, izingxenye eziqhutshwayo phakathi kwezigaba zingamaphakheji aqinile okufakwa ngaphakathi, izintambo zangaphandle zamukela amajoyinti ekhebula avikelekile, futhi ibhasi lokuxhuma iyunithi elisebenzayo lithatha amabhasi avikelwe. Ngakho-ke, ukuphepha kokusetshenziswa kuthuthukiswa kakhulu, indlela yokusebenza ithatha indlela yasentwasahlobo, futhi impilo yomshini ingaphezu kwezikhathi ezingu-10,000. Idatha yokusebenza kwayo nesimo semishini ingagadwa futhi igadwe ukude, futhi inganakwa. Kuyidivayisi yokusabalalisa amandla enohlobo lokusebenza.
Lawa mayunithi alandelayo angakhethwa kukhabhinethi ukuze akhe iyunithi yokuphakela ugesi eyongayo nesebenzayo:
1. Iyunithi ye-vacuum circuit breaker (630A, 20-25kA)
2. Iyunithi yokushintsha umthwalo we-vacuum (630A, 20-25kA)
Izici Zomkhiqizo
1. Ukuvikelwa kwemvelo
Zonke izinto ezisetshenziswa ekwenziweni komkhiqizo azinabuthi futhi azinabungozi. I-N2 noma umoya owomile usetshenziswa njengendawo yokuvikela ukushisa ukuze kuncishiswe ukukhishwa kwesisi esibamba ukushisa nokufeza izinjongo zokuvikela imvelo. Azikho izinto ezinobuthi neziyingozi ezikhishwayo ngesikhathi sokusetshenziswa. Ingasetshenziswa kabusha futhi isetshenziswe kabusha, okunquma ukuvikelwa kwemvelo kokusetshenziswa.
2. Uhlu olubanzi lohlelo lokusebenza
Ungasebenzisi noma yimaphi amagesi anobuthi futhi ayingozi, anquma ukuphepha kwendawo yokusetshenziswa. Kungakhathaliseki ukuthi kumagumbi angaphansi, emihubheni, emikhunjini nasezindaweni ezihlukahlukene ngaphakathi nangaphandle. Ingaphakathi lekamelo elinomfutho ophezulu lingagcwaliswa ngomoya owomile noma i-nitrogen, efanele izimo ezinzima ezifana: ukuphakama okuphezulu, umoya onamandla nesihlabathi, izinga lokushisa eliphansi, amakhaza amakhulu, izidingo eziphakeme zokuvikela imvelo, izindawo zokusebenza njalo, ukuphepha. amasayithi angaqhumi, inkungu enosawoti omningi, kanye nokusetshenziswa okuphephile ngaphansi kwezimo zokujiya . Ifakwe ngokugcwele futhi ivalwe ngokugcwele, ifaneleka ukuthi imishini iqhubeke nokusebenza ngemva kokuthatha izinyathelo ezithile zokuhlanza nokomisa ngemva kwesikhathi esifushane sokungena kwamanzi.
3. Ayinasondlo
Ngaphezu komshini wokusebenza, i-GHXH-12 yokuvikela imvelo igesi-insulated main unit series isesimweni esivalwe ngokugcwele, ingxenye yokushintshwa kwe-high-voltage ivalwe ngokuphelele, ukuze kugwenywe ukuhlanzwa nokugcinwa kokunakekelwa, kanye nezindleko ukusebenza nokugcinwa kungancishiswa.
Izinga le-automation ye-switchgear liphezulu kakhulu, futhi umsebenzi wokuthola i-inthanethi uzokwazisa umsebenzisi ngokusebenza kwemishini ngesikhathi sangempela, okulungele kakhulu ukuzenzekelayo kwenethiwekhi yokusabalalisa, ukunciphisa izindleko zokusebenza, futhi kunciphisa izindleko zokukhiqiza zezinkampani zamandla.
4. Ukuvikeleka okuphezulu
Uhlelo oluphelele lokuxhumanisa nokuxhumanisa, ibanga lokuhlukanisa lezigaba ezintathu libonakala ngokucacile, ligwema ukuvela kwezingozi zokusebenzisa kabi. Ukusetshenziswa kwegesi ye-SF6 kukhanseliwe, futhi isakhiwo sokuhlukanisa i-interphase siyaqiniswa ukuze kugwenywe ingozi yokwanda noma yokuqhuma okubangelwa ukujikeleza okufushane phakathi kwezigaba noma amasekhethi amaningi. Isiphazamisi se-vacuum esinamandla e-vacuum ekhabetheni legesi elivikela ukuqhuma kwemvelo siyamukelwa, futhi isigxobo esivalwe ngokuqinile sinokusebenza okwengeziwe kokuvikela kweswishi.
5. Kulula ukusebenza
Iswishi yokunqamula kanye nomhlaba inesibambo esisodwa sokusebenza, futhi asikho isidingo sokukhomba nokukhathazeka ngamaphutha. Uma i-circuit breaker isebenza, isibambo sokusebenza sokunqanyulwa kanye neswishi yomhlaba ayikwazi ukusebenza, futhi ukuqeqeshwa kobuchwepheshe okuyinkimbinkimbi akudingeki, okwenza ukusebenza kube lula kakhulu, ukugwema amaphutha okusebenza.
