Chiyambi cha Chipinda Chachikulu cha Mphete

Kabati ya netiweki ya mphete imadziwika kuti SF6 load switch ndi SF6 load switch + fuse combination appliance yomwe imagwiritsidwa ntchito mu ring network line kapena terminal. SF6 load switch ndi load switch yabwino kwambiri yomwe ogwiritsa ntchito ambiri adakumana nayo m'zaka zaposachedwa. Kuphatikiza pa zabwino za moyo wautali wamagetsi, mphamvu yosweka yamphamvu komanso vacuum load switch, zabwino zake zazikulu ndizosavuta kupeza malo atatu ogwirira ntchito (pa, pa, ndi pansi), mphamvu yaying'ono (inductance, capacitance) yotsegulira ndi kuswa, komanso mphamvu yamphamvu yolimbana ndi nyengo zovuta zachilengedwe. Ndi yoyenera kutchuka ndikugwiritsidwa ntchito mu mizinda ndi kumidzi yogawa magetsi apakati.

Kabati ya netiweki ya mphete nthawi zambiri imagawidwa m'mitundu iwiri: chotenthetsera mpweya ndi chotenthetsera cha SF6. Chimagwiritsidwa ntchito kugawa ndi kutseka mphamvu ya katundu, kutsegula ndi kuswa mphamvu yafupifupi yamagetsi ndi mphamvu ya transformer yopanda katundu, komanso kuyatsa mphamvu ya mzere wozungulira ndi chingwe pamtunda winawake. Chimagwira ntchito yowongolera ndi kuteteza, ndipo ndi chida chofunikira chosinthira magetsi a netiweki ya mphete ndi magetsi oyambira. Mu thupi la kabati, chotenthetsera chodzaza chokhala ndi chotenthetsera mpweya chimaphatikizapo mtundu wopanga mpweya, mtundu wa kupanikizika ndi mtundu wa vacuum. Chotenthetsera chodzaza chokhala ndi chotenthetsera cha SF6 ndi mtundu wa SF6. Chifukwa mpweya wa SF6 umatsekedwa mu chipolopolo, kusweka kwa magawo komwe kumapangidwa ndi icho sikuoneka. Chotenthetsera chodzaza mu kabati ya netiweki ya mphete nthawi zambiri chimafuna malo atatu, ndiko kuti, kudula katundu, kupatula dera, kotheka poyika pansi. Mtundu wopanga gasi, mtundu wa kupanikizika ndi chotenthetsera cha mtundu wa SF6 n'zosavuta kukwaniritsa malo atatu, ndipo chipinda chozimitsira cha vacuum arc chingasweke kokha, sichingalekanitsidwe, kotero chotenthetsera cha netiweki cha vacuum load ring chomwe chimagwiritsidwa ntchito powonjezera chotenthetsera chosungunula chisanalowetsedwe, kuti chipange chotenthetsera chosungunula.

Chosinthira mphamvu ndi mtundu wa chipangizo chosinthira mphamvu chomwe chili ndi chipangizo chozimitsira mphamvu chosavuta. Chosinthira mphamvu chomwe chimagwiritsa ntchito mpweya wa SF6 ngati chotenthetsera mphamvu ndi chozimitsira mphamvu chotchedwa SF6 load switch. Chingagwiritsidwe ntchito kuyatsa ndi kutseka mphamvu yodzaza mphamvu ndikuwonjezera mphamvu, komanso chingagwiritsidwenso ntchito kuyatsa ndi kutseka mizere yopanda katundu, ma transformer opanda katundu ndi ma capacitor banks, ndi zina zotero. Chosinthira mphamvu chogwira ntchito cha ma biti atatu chokhala ndi ntchito za pa, off ndi ground chili ndi mawonekedwe osavuta komanso mtengo wotsika. Chosinthira mphamvu chokha sichingachotse mphamvu yamagetsi yafupikitsa.

Chosinthira cha SF6 load switch + fuse combination appliance chimayendetsedwa ndi SF6 load switch kuti chikhale ndi overload current (overload current ya SF6 load switch ikadali mkati mwa load switch yomwe yayesedwa kuchoka pa current) ndi current yogwira ntchito bwino yomwe imatseka ndikusweka, ndipo imafunanso kuti "transfer current" izimitsidwe. Ma fuse a high voltage ndi omwe amachititsa kuti pakhale chitetezo cha short circuit ndi overload protection kumbali ya high voltage. Pakadali pano, gulu la SF6 load switch ndi ma fuse atatu okhala ndi zoyambitsa, bola ngati pali choyambitsa chilichonse, njira yake yolumikizira idzapangitsa kuti load switch ikhale ndi magawo atatu okha. Kuphatikiza kwa awiriwa kumatha kukwaniritsa zofunikira za chitetezo cha ntchito yogawa mphamvu pansi pa mikhalidwe yabwinobwino komanso yolakwika.

Kabati ya netiweki ya mphete ingagawidwe m'magulu awiri: netiweki ya mphete yamkati ndi netiweki ya mphete yakunja.

Netiweki yamkati nthawi zambiri imagwiritsidwa ntchito pogawa mphamvu mbali yamagetsi okwera. Imapangidwa ndi kabati yolowera, kabati yoyezera, kabati ya PT ndi kabati yotulutsira transformer. Kwa ogwiritsa ntchito omwe ali ndi mphamvu zambiri, mzere wolowera uyenera kugwiritsa ntchito kabati yosinthira magetsi awiri. Chipinda chachisanu ndi chiwiri chinati "tsopano anthu ena adzayika switch ndi fuse kuphatikiza kwa kabati yosinthira magetsi okwera otchedwa ring network cabinet, makamaka ndikosavuta kusiyanitsa ndi kabati yosinthira magetsi" sizolondola, kabati ya ring network ilinso ndi pulogalamu yosinthira magetsi

Netiweki ya mphete yakunja nthawi zambiri imagwiritsidwa ntchito mu gridi yamagetsi yamzinda, pogwiritsa ntchito kabati ya SF6 ring network yamtundu wa bokosi wamba, khalidwe lalikulu la kabati yamtunduwu ndilakuti mulingo woteteza ndi wapamwamba, ukhoza kuchita IP67, woyenera panja, ndipo ukhoza kuviikidwa m'madzi kwa kanthawi kochepa. Dongosolo la magetsi a netiweki ya loop nthawi zambiri limagwiritsa ntchito loop imodzi mkati, loop imodzi kunja, kawiri kapena katatu kuti lichite dera lotuluka, ndiko kuti, kupanga mawonekedwe amagetsi a netiweki ya loop m'manja.

Pofuna kutsimikizira kudalirika ndi kupitiriza kwa magetsi, mizere iwiri yolowera imagwiritsidwa ntchito kupereka magetsi, yomwe imapanga mphete. Chosinthira cha SF6, malo atatu (kutseka, kutsegula, kuyika pansi), mzere wa nthambi, transformer.
