III. Izici Zokwakhiwa
1. Amayunithi Angashintshi, Angama-modular
Umzimba wekhabhinethi wenziwe ngeshidi le-zinc eligoqwe nge-aluminium nesakhiwo esihlanganiswe ngokuphelele, ngaphandle kwamaphuzu okubheduka, amandla aphezulu, nokumelana okuhle nokugqwala; yamukela umklamo we-modular, ongahlanganiswa ngokukhululeka ube umugqa wokungena, umugqa wokuphuma, inethiwekhi eyindilinga, i-PT, ukulinganisa namanye amakhabhinethi asebenzayo.
2. Ukuhlukaniswa kwamakamelo
Kusukela phezulu kuye phansi, kuhlanganisa: igumbi lezinsimbi, igumbi le-busbar, igumbi lokushintsha, igumbi le-fuse, kanye negumbi lezintambo. Isigaba ngasinye sihlukaniswe ngokuzimela, siqinisekisa ukuphepha okuphezulu futhi singabikho ukuphazamiseka ngesikhathi sokugcinwa.
3. Ukucushwa Kwesishintshi Esikhulu
I-HXGN15-12(F): Ifakwe i-FLN36-12D SF₆ load switch (izikhundla ezintathu: ukuhlukanisa / ukulayisha / ukubeka phansi)
HXGN15-12(F·R): Kuhlome ngesishintshi somthwalo se-SF₆ - ugesi wokuhlanganisa i-fuse, osasetshenziswa ukuvikela i-transformer
I-vacuum load switch ongayikhetha, izinketho ze-vacuum circuit breaker
4. Izikhiya eziphelele "zokuvimbela ezinhlanu"
Izikhiye zemishini ziyadingeka phakathi kweswishi yokulayisha, iswishi yokubeka phansi, nomnyango wekhebinethi ukuze kufezekiswe:
Vimbela Ukushintsha Okungalungile Kwesishintshi
Vimbela ukudonsa iswishi yokuhlukanisa ngenkathi kukhona umthwalo
Vimbela ukuxhuma isishintshi sokubeka phansi ngenkathi kukhona ugesi
Vimbela ukufakwa kukagesi ngenkathi kuxhunywe ku-grounding
Vimbela ukungena egumbini elinegesi
5. Ukusebenza Okulula
Isishintshi somthwalo sihlome ngomshini wentwasahlobo, sisekela ukusebenza ngesandla/ngogesi; isishintshi sokubeka phansi sisebenza ngesandla, sinamandla okusebenza alula nokwethembeka okuphezulu.
IV. Izinzuzo Zokusebenza
1. Okuncane futhi Okonga
Ububanzi be-cabinet bungama-375–750mm kuphela, buthatha isikhala esincane futhi bubiza kancane, bufanele amagumbi okusabalalisa kanye neziteshi zamandla ezincane ezinendawo elinganiselwe.
2. Ukuzivumelanisa Nemvelo Okunamandla
Ukuhlanganiswa komoya, isakhiwo esilula, esifanele izindawo ezijwayelekile zasendlini, ingasetshenziswa endaweni engu-≤ 1000m nobubanzi bokushisa obungu -5℃ kuye ku-+40℃.
3. Akudingi ukugcinwa, Isikhathi Eside Sokusebenza
Ama-SF₆ switches awanawo umonakalo noma ukuqoqeka kodlame, adinga ukugcinwa iminyaka eminingi yokusebenza okuvamile; impilo yemishini ≥ izikhathi ezingama-2000.
4. Ukunwetshwa Okuguquguqukayo
Isakhiwo esihlangene singahlanganiswa sibe ama-cabinet amaningi ukwakha ngokushesha amanethiwekhi anomjikelezo, izimiso ezimbili zamandla, kanye nezinhlelo zokusabalalisa zokugcina.
V. Ukucushwa Okujwayelekile
Isishintshi Esikhulu: FLN36-12D SF₆ isishintshi somthwalo / isishintshi somthwalo we-vacuum
Ukuvikelwa: Isishintshi somthwalo + i-fuse (uhlobo lwe-F·R), noma ifakwe ukuvikelwa kwe-microcomputer
I-Grounding Switch: Uchungechunge lwe-JN15
Okwesibili: Izinsimbi, ukubonisa ugesi, i-CT/PT, izivikelo zombani
Ukusebenza: Imishini Yesiphethu Yesandla / Kagesi
VI. Isifinyezo sezimo lapho kungasetshenziswa khona i-HXGN15-12 iyisixazululo esingabizi kakhulu sezinto eziyinhloko zokuhlinzekwa kwamandla enethiwekhi ye-ring engu-10kV. Ngezici eziyinhloko ezithi "ziyancipha, zithembekile futhi azibizi kakhulu", kuyisixazululo esikhethwayo sokusabalalisa ugesi ezindaweni zokugcina zamagridi kagesi emadolobheni, ezindaweni zokuhlala, kumathuluzi okuguqula amabhokisi, ezinkampanini zezimboni nezimayini, njll.
