KUGWIRITSA NTCHITO SF6 LOAD SWITCH MU NETWORK YOGAWIRITSA NTCHITO

Kugwiritsa ntchito SF6 Load Switch mu Distribution Network

Ma switch apakati-voltage omwe amagwiritsidwa ntchito m'malo olumikizira ma hub onse amagwiritsa ntchito ma circuit breakers ngati zida zowongolera ndi kuteteza, ndipo ayenera kukhala ndi automatic reclosing. Komabe, mphamvu yamagetsi ya siteshoni iliyonse yogawa magetsi mu netiweki ya ring nthawi zambiri si yayikulu, mphamvu yake yovotera ndi yaying'ono kuposa mphamvu yovotera ya netiweki ya ring, ndipo reclosing sikofunikira, kotero gawo lamagetsi la siteshoni yogawa magetsi ya netiweki ya ring limatha kugwiritsa ntchito kapangidwe kosavuta, mtengo wotsika komanso magwiridwe antchito apamwamba. Kuphatikiza kwa load switch + fuse komwe kungakwaniritse zofunikira.

Kuphatikiza kwa load switch ndi fuse kuti zilowe m'malo mwa circuit breaker yachikhalidwe kwakhala kukuchitika kunja kwa dziko kwa zaka makumi asanu. Chiŵerengero cha mphamvu ya circuit breaker ndi 1:2.5, chomwe chidakali kutali kwambiri ndi mayiko otukuka. Zimasonyezanso kuti m'dziko langa, SF6 load switch ili ndi mwayi waukulu pakukula kwa ma network ogawa magetsi apakati.

Mwachidule, poyerekeza kugwiritsa ntchito ma switch a SF6 load ndi ma circuit breaker m'ma network ogawa ang'onoang'ono, mfundo zotsatirazi zitha kufotokozedwa mwachidule:

Chotsekera magiya chimagwira ntchito limodzi ndi chitetezo cha relay ndipo chili ndi zonse

Chitetezo ndi ntchito yogwira ntchito.

Chosinthira cha SF6 chimagwira ntchito yofanana ndi chosinthira ma circuit, koma sichingathe kusokoneza ma short circuit (sichofunikira).

Kagwiridwe ka ntchito ka SF6 load switch yomwe imaswa transformer yopanda katundu ndi kabwino kuposa ka circuit breaker.

Chosinthira cha SF6 load + fuse yoletsa magetsi imathanso kuswa ma short circuit nthawi imodzi, zomwe zimakhala zofanana ndi choswa ma circuit.

Chosinthira cha SF6 load + fuse yoletsa magetsi si yoipa kuposa chosokoneza magetsi, koma mtengo wake ndi wotsika kwambiri.
