Ukusetshenziswa kanye nezici ze-DC isolation switch

Iswishi yokuhlukanisa i-DC iyithuluzi lokuvimbela ukujikeleza okufushane phakathi kwe-AC ne-DC yeswishi yokuhlukanisa i-DC. Ixhunywe nesiguquli esihlukanisayo phakathi kwetheminali yokufaka amandla ekhabetheni lokushintshwa kwamandla kagesi we-AC kanye nolayini wokufaka wamandla we-AC wezigaba ezintathu, kanye nokokufaka kwamandla kagesi we-AC wezigaba ezintathu. Ulayini uxhunywe nokuvunguza okuyinhloko kwe-transformer yokuhlukanisa, futhi ukuvuthwa kwesibili kwe-isolation transformer kuxhunywe nesiphetho sokungena kwamandla kwekhabhinethi yokushintsha amandla kagesi we-AC.

Iswishi ye-DC isolation ixazulula isistimu yokulawula ye-DC isolation switch kubuciko bangaphambili. Ngenxa yokulimala kwesivikeli phakathi kwegobolondo lemoto eyi-AC kanye nendlela yokwehlisa amandla ngamandla e-DC nezinye izizathu, amandla okufaka isivikelo ayancipha, noma lapho kuvuza injini ye-AC, izingozi ze-AC kanye ne-DC . Ivikela ngempumelelo ukusebenza okuphephile kwezinto zokusebenza zokulungisa ukuphakelwa kwamandla futhi ivimbele ukulahlekelwa okukhulu kwezomnotho nokulimala komuntu siqu.

Ububanzi besicelo

Iswishi yokuhlukanisa i-DC ifanele ukuvikelwa kokuzihlukanisa emigqeni enama-voltage okusebenza afika ku-1000VDC futhi ikalwe ama-currents afika ku-100A, futhi ibona ukusatshalaliswa komthwalo.

ukunqanyulwa nokuhlukaniswa okusebenzayo. Isetshenziswa kakhulu emkhakheni we-photovoltaic.

I-DC isolation switch ifaneleka kakhulu ukufakwa endlini nge-AC 50/60Hz, i-voltage elinganiselwe engu-1500V, i-voltage ephezulu engu-1000V, kanye nesilinganiso samanje esingu-200A no-400A. Ngaphezu kokusetshenziselwa ukushintsha izinto zikagesi, ama-switch ahlukanisayo e-DC angasetshenziselwa ukwenza njalo nokuphula amasekhethi.

Izici zesakhiwo

Uchungechunge lwe-ADELS L2 DC lunqamula amaswishi

Okubaluleke kakhulu ukuthi ukusetshenziswa ngempumelelo kwalobu buchwepheshe kwenza izwe lethu libe nobuchwepheshe bokupholisa bamajeneretha amakhulu amakhulu ngaphandle kwamalungelo empahla yengqondo. Ekuqaleni kwekhulu lama-21 ezweni lami, kuzoba nenani elikhulu lama-hydro-generator amakhulu futhi amakhulu kakhulu alindele ukuthuthukiswa nokukhiqizwa, futhi ukupholisa kungenye yobuchwepheshe obubalulekile. Izinzuzo ezivelele zokuzivumelanisa nezimo ngokuphelele, ngakho izinzuzo ezilindelekile zezomnotho nezenhlalakahle zizoba zinkulu.

Iswishi yokunqamula i-DC ivela ekuhlanganiseni kwemishini kagesi, ukwakheka kwemoto, ubunjiniyela be-thermophysics kanye ne-dielectric electrochemistry, futhi inokuqukethwe okucebile. Kodwa-ke, isakhiwo esidingekayo ukuze usiqaphele ku-motor asiyona inkimbinkimbi, ngakho-ke ukusetshenziswa kwalobu buchwepheshe kubanzi. Ngokuvamile, i-hydro-generator enamandla angaphezu kwama-megawatts angu-200 ingathola izinzuzo ezinhle zezomnotho ngokusebenzisa lobu buchwepheshe. Kumayunithi aqala kaningi (njengezimboni zamandla ezimpontshwa) noma adinga amandla akhiqiza kakhulu (okuhlanganisa nokunwetshwa kwamandla), kuzoba nemiphumela engcono.
