17.5kV Iyunithi Eyinhloko Yekhala (imbobo yokuhlola ikhebula yangaphandle) Isithombe Esifakiwe

17.5kV Ring Main Unit (imbobo yokuhlola ikhebula yangaphandle)

Incazelo emfushane:

Uchungechunge lwe-SS olufakwe igesi ngokugcwele, iyunithi eyinhloko eyindandatho ehlangene i-SF6 gas-insulated medium-voltage switchgear ethuthukiswe yi-Seven Stars Electric.Umkhiqizo wamukela idizayini eyimojula engahle ihlelwe ngokungafanele ngokuvumelana nezikimu zokuklama ezihlukene futhi iyinhlanganisela ephelele yeyunithi yebhokisi evamile kanye neyunithi enwetshiwe, enganelisa izidingo zeziteshi ezingaphansi ezihlukahlukene zesibili zokusetshenziswa okuguquguqukayo kwe-compact switchgear.
Amadivayisi e-switchgear ochungechunge lwe-SS angamasistimu avalwe ngokugcwele, anazo zonke izingxenye ezibukhoma namaswishi avalelwe ngaphakathi kwezivalo zensimbi engagqwali.Abavikelekile emithonyeni yemvelo futhi banikeze ukusebenza okuthembekile.Imikhiqizo ibonakala ngokwakheka okuhlangene, ukusebenza okungenakulungiswa, nokuphila isikhathi eside, ehlangabezana nezidingo zokusebenza kwangaphakathi nangaphandle.Imikhiqizo isiphumelele isitifiketi sokuhlolwa kohlobo lwesikhungo sikazwelonke sokuhlola i-High Voltage Apparatus Testing Center futhi isetshenziswa kabanzi emikhakheni ehlukahlukene ehlanganisa iziteshi ezisatshalaliswayo, i-box-type switchgear, amabhizinisi ezimboni nezimayini, izikhumulo zezindiza, izitimela, izindawo zentengiso, izakhiwo eziphakeme. , imigwaqo emikhulu, imizila ehamba ngaphansi, imigudu, nezimo zemvelo ezinzima.

Ipharamitha yobuchwepheshe eyinhlokos

Isici soMkhiqizo

I-SF6 insulating medium
I-SF6 ifaneleka kakhulu ukufakwa kwe-insulation kanye ne-arc yokucima umlilo ngenxa yomthamo wayo ophezulu kakhulu wokushisa ukushisa, okungahlakaza ngokushesha ukushisa ngesikhathi sokushisa kwe-arc, ukuhanjiswa okuphezulu kwe-thermal ku-zero yamanje, okungenza i-arc ipholile nezinye izici eziphakeme.
Ukubekwa uphawu okuhle
Ithangi legesi lenziwe ngensimbi engagqwali engu-2mm elibunjiwe labe selishiselwa, futhi ukuthwala ku-shaft yokushintsha insimbi engenasici kuthatha isakhiwo esikhethekile sokuvala ungqimba oluphindwe kabili, okuqinisekisa ukuthi ithangi legesi linokuqina komoya okuhle kakhulu. Izinga lokuvuza lonyaka Igesi ye-SF6 ingu-≤0.01%.Qinisekisa ukuthi impilo yemishini ingaphezu kweminyaka engama-30.
Ihlangene futhi ayinakulungiswa
Umkhiqizo wamukela idizayini eyi-modular, ukwakheka okuhlangene, unyawo oluncane, ukufakwa kalula nokungakhathalelwa.
I-automation interfaces
Ukushintshwa kweyunithi ye-motor-drive kugcinelwe ukuxhumana kwe-automation yenethiwekhi yokusabalalisa, futhi ukuxhumana ne-RTU kulula futhi kulula.Isikhundla sokufaka i-RTU sigcinwe kwikhabhinethi.
Izinqubo Ezithuthukile
Ukunemba kokukhiqizwa kwethangi legesi, ukusetshenziswa kwe-laser cutting kanye ne-CNC punching, ukunciphisa, ukugoqa kanye nezinye izinto zokuqinisekisa ukuthi ukunemba kobukhulu bezingxenye zethangi legesi, ukusetshenziswa kwamarobhothi wokushisela, inqubo yokushisela okuzenzakalelayo ukuqinisekisa ukusebenza kahle kwe-welding, ikhwalithi ezinzile. wethangi legesi, i-weld seam enhle, ukuvimbela ukuvuza kwegesi ethangini legesi kanye nokuhlasela komswakama ovela ngaphandle, ukukhulisa ukuvikelwa kochungechunge lwe-SSU lwamakhabethe aphefumulayo, ukusebenza kokuzinza kwekhabhinethi.
Indlela yokuxhuma ibhasbha
I-cone casing yangaphakathi isethwe ohlangothini lwekhabethe le-switchgear, kusetshenziswa irabha ye-silicone njenge-insulating material, futhi isetshenziselwa ukubona ukusetshenziswa kohlobo olufanayo lweyunithi eyinhloko yendandatho enamayunithi amabhokisi ajwayelekile ahlukene noma igumbi elilodwa legesi ngokusebenzisa isixhumi sebha yebhasi. ukuhlanganisa ikhabethe.
Amadivayisi angaqhumi
Ithangi ngalinye lifakwe ulwelwesi olungaqhumi olukalwe ngenhla kuka-0.2MPa ukuze kuncishiswe ingcindezi uma kwenzeka ukungasebenzi kahle.I-membrane engashi ingahle ibekwe phansi noma ngaphezulu kwethangi.

Ukucushwa Ongakukhetha

Isikhombi Sephutha
Izinkomba zephutha zisetshenziswa kakhulu kuyunithi eyinhloko eyindandatho ehlukahlukene, i-switchgear ephezulu kanye nebhokisi legatsha lekhebula lesistimu yamandla, elikwazi ukubona ngokunembile nangokwethembeka isigaba samaphutha kanye nohlobo lwamaphutha wegridi yamandla.Ukusetshenziswa kwesikhombi sephutha le-cable short-circuit ground fault kuyindlela ephumelelayo yokuthola amaphutha ekhebula, kuyindlela ephumelelayo yokuthuthukisa izinga lokusebenza kwenethiwekhi yokusabalalisa kanye nokusebenza kahle kokusingatha ingozi.Idizayini yokusetshenziswa kwamandla aphansi, ibhethri ye-lithium ephezulu noma amandla angaphandle, impilo yebhethri ende;isakhiwo sangaphandle sisebenzisa umklamo wohlobo lwekhadi, wonke umshini ulula futhi ulula ukulayisha nokuthulula.

Idivayisi Yokuvikela I-Microcomputer
Idivayisi yokuvikela ikhompyutha encane ezisebenza yona inezinzuzo zokuhlanganiswa okuphezulu, ukumiswa okuphelele kokuvikela, ikhono eliqinile lokulwa nokuphazamiseka, ukusetshenziswa kwamandla aphansi, ukumelana nezindawo ezinokhahlo, njll. Ifaneleka ngokukhethekile ukufakwa okuqondile okugxilile kukhabhinethi ye-switchgear ukuze kuqashelwe isilinganiso. , ukuqapha, ukulawula, ukuvikela, ukuxhumana neminye imisebenzi yeyunithi ye-circuit breaker.Ukuvikelwa kwe-microcomputer okuzenzela amandla kanye ne-microcomputer esebenzayo kungakhethwa ngokuya ngezidingo zangempela, futhi inkampani yethu izohlinzeka ngezinketho zamabhrendi amaningi.

I-Transformer yamanje
I-transformer yamanje esekelwe kumgomo wokungeniswa kwe-electromagnetic induction izoba uhlangothi oluyinhloko lwamanje olukhulu lube ohlangothini lwesibili lwamanje oluncane lokulinganisa amandla, ukuvikelwa kwe-relay, ukulawula okuzenzakalelayo namanye amadivaysi ukuze anikeze amasignali emishini yamandla, abambe iqhaza ukuvikela nokuqapha imishini eyinhloko, ukwethembeka komsebenzi wayo ekusebenzeni okuphephile kwalo lonke uhlelo lwamandla kubaluleke kakhulu.
