I-GVG-12 Solid Insulated Ring Network Switchgear

Uhlolojikelele

I-GVG-12 yochungechunge oluqinile lwe-insulated ring switchgear iyisishintshi se-vacuum esivaleke ngokuphelele, esivalwe ngokugcwele, esinganakekeli. Zonke izingxenye eziphilayo ezinamandla kagesi aphezulu zibunjwe nge-epoxy resin esebenza kahle kakhulu, futhi isiphazamisi se-vacuum, isekethe eyinhloko ye-conductive, ukwesekwa kwe-insulating, njll. kuhlanganiswe ngokuphilayo kube okuphelele, futhi amayunithi asebenzayo axhunywe ibha yebhasi eqinile efakwe ngokuphelele. . Ngakho-ke, yonke i-switchgear ayithinteki imvelo yangaphandle, futhi ukuthembeka kokusebenza kwedivayisi nokuphepha komqhubi kungaqinisekiswa.

I-switchgear yenethiwekhi yendandatho inezici zesakhiwo esilula, ukusebenza okuguquguqukayo, ukuvala okuthembekile, ukufakwa okulula, njll. Ifaneleka ku-50Hz, isistimu yamandla angu-12kV, futhi isetshenziswa kabanzi kumanethiwekhi endandatho yezimboni kanye neyomphakathi kanye namaphrojekthi we-terminal network wokusabalalisa, njengoba ukwamukela nokusatshalaliswa kwamandla kagesi, kufanelekile ikakhulukazi ukusatshalaliswa kukagesi ezindaweni zokuhlala zasemadolobheni, iziteshi ezincane, iziteshi zokushintsha, amabhokisi egatsha lezintambo, iziteshi ezincane zohlobo lwamabhokisi, amabhizinisi ezimboni nezimayini, izitolo ezinkulu, izikhumulo zezindiza, imigwaqo engaphansi komhlaba, ukukhiqizwa kwamandla omoya. , izibhedlela, izinkundla, izitimela, imigudu, njll. ukusetshenziswa. Ngenxa yokuthi umkhiqizo unezinzuzo ze-insulate ngokugcwele, ivalwe ngokugcwele, futhi ivikeleke ngokugcwele, ulungele ukusetshenziswa ezindaweni ezinokuphakama okuphezulu, izinga lokushisa eliphezulu, ukushisa okumanzi, amakhaza amakhulu, kanye nokungcola okubi kakhulu.

Ukwakheka Komkhiqizo

● I-GVG-12 switchgear ngokuyinhloko inezinhlobo ezintathu zamayunithi asebenzayo, okuyiyunithi engu-V (iyunithi ye-circuit breaker), iyunithi engu-C (iyunithi yokushintsha ukulayisha), kanye neyunithi engu-F (iyunithi kagesi ehlanganisiwe). Uma isistimu idinga amayunithi amaningi ukuthi amiswe, anganwetshwa ngokungafanele ohlangothini lwesobunxele nakwesokudla futhi ahlelwe ngokuya ngezikimu zedizayini ezihlukene ukuze kuzuzwe izidingo zokucushwa ezihlukene.

● Iyunithi ngayinye ihlukaniswe yaba izingxenye ezintathu: igumbi lezinsimbi, indlela yokusebenza, kanye nesekhethi eyinhloko. Igumbi lezinsimbi lingahlonyiswa ngokuvikelwa kwe-microcomputer (isilawuli esihlakaniphile) namanye amamitha. Indlela yokusebenza iwumshini wokusebenza wasentwasahlobo ozinikele, noma umshini osebenza ngogesi; umjikelezo oyinhloko wamukela inqubo yejeli ezenzakalelayo ye-APG, ishumeke ngokuphelele ibha yebhasi, isixhumi nesiphazamisi se-vacuum ku-epoxy resin, futhi isebenzise izixhumi ezizinikezele nemigoqo yebhasi ukuxhuma.

● I-GVG-12 i-solid-insulated switchgear inezinzuzo zesakhiwo esihlangene, i-insulated ngokugcwele, impilo ende, ukunganakekeli, ukusebenza kwendawo encane, ukuphepha nokuthembeka, futhi ayithinteki endaweni yokusebenza. Isetshenziswa kabanzi kumanethiwekhi endandatho yezimboni neyomphakathi kanye nezinsiza zamandla ezigcinayo. Ikakhulukazi ezifanele iziteshi ezincane zokusabalalisa ugesi wesibili, iziteshi zokuvula nokuvala, izimboni nezimayini, izikhumulo zezindiza, izitimela, izifunda zezentengiselwano, izakhiwo eziphakeme, imigwaqo emikhulu, imigwaqo engaphansi komhlaba, imigudu neminye imikhakha.

Izici

Ukusebenza okuhle kakhulu kwe-epoxy resin

● I-GVG-12 i-switchgear eqinile evalekile evalwe ngokugcwele ikhiqizwa kusetshenziswa i-epoxy resin ekhethekile njengento efakwayo. Le resin ye-epoxy inezici ezinhle kakhulu:
