Ukusetyenziswa kunye neempawu zokutshintsha kwe-DC ukuzihlukanisa

I-DC yokuhlukanisa iswitshi sisixhobo sokuthintela isiphaluka esifutshane phakathi kwe-AC kunye ne-DC ye-DC yokuhlukanisa iswitshi. Idityaniswe ne-transformer yodwa phakathi kwe-terminal igalelo lombane we-AC motor power switch switch khabhathi kunye nesigaba sesithathu somgca wokufakelwa kwamandla we-AC, kunye negalelo lesigaba sesithathu sombane we-AC. Umgca uqhagamshelwe kunye ne-primary winding ye-transformer yokuzimela, kwaye ukutshatyalaliswa kwesibini kwe-transformer yokuzimela idibaniswe ne-inlet yamandla ekupheleni kwe-AC motor power supply switch cabinet.

Ukutshintsha kokwahlula kwe-DC kuyisombulula inkqubo yolawulo ye-DC yokwahlula iswitsha kubugcisa bangaphambili. Ngenxa yomonakalo we-insulator phakathi kweqokobhe lemoto ye-AC kunye nendlela yokunciphisa amandla e-DC kunye nezinye izizathu, amandla e-insulator ayancipha, okanye xa imoto ye-AC ivuza, iingozi ze-AC kunye ne-DC ezifutshane. . Ikhusela ngokukhuselekileyo ukusebenza okukhuselekileyo kwezixhobo zokulungiswa kombane kwaye inqanda ilahleko enkulu yezoqoqosho kunye nokwenzakala komntu.

Ubungakanani besicelo

I-DC yokuhlukanisa i-switch ifanelekile ukukhuselwa kwe-isolation kwimigqaliselo kunye ne-voltages yokusebenza ukuya kwi-1000VDC kwaye ilinganiswe imisinga ukuya kwi-100A, kwaye iqonda ukuhanjiswa komthwalo.

uqhawulo kunye nokwahlula okusebenzayo. Isetyenziswa kakhulu kwintsimi ye-photovoltaic.

I-DC isolation iswitshi ilungele kakhulu ukufakelwa kwangaphakathi kunye ne-AC 50/60Hz, i-voltage elinganisiwe ye-1500V, i-voltage ephezulu ye-1000V, kunye ne-rerated current ye-200A kunye ne-400A. Ukongeza ekusetyenzisweni ekutshintsheni unikezelo lwamandla, i-DC yokuhlukanisa iiswitshi inokusetyenziselwa ukwenza kunye nokwaphula iisekethe ezingaqhelekanga.

Iimpawu zesakhiwo

I-ADELS L2 uthotho lwe-DC yokuqhawula iiswitshi

Okubaluleke ngakumbi kukuba ukusetyenziswa ngempumelelo kobu buchwepheshe kwenza ukuba ilizwe lethu libe nobuchwephesha bokupholisa beejenereyitha ezinkulu zamanzi ngaphandle kwamalungelo epropathi enomgangatho ophezulu wokuqonda. Ekuqaleni kwenkulungwane yama-21 kwilizwe lam, kuya kubakho inani elikhulu leejenereyitha ezinkulu nezinkulu kakhulu ezilindele ukuphuhliswa nokuveliswa, kwaye ukupholisa yenye yeetekhnoloji eziphambili. Iinzuzo ezibalaseleyo zokuziqhelanisa ngokupheleleyo, ngoko ke inzuzo elindelekileyo yezoqoqosho nezentlalo iya kuba nkulu.

Isitshixo sokuqhawula i-DC sivela ekudityanisweni koomatshini bombane, ubume bemoto, i-thermophysics yobunjineli kunye ne-electric electrochemistry, kwaye inomxholo otyebileyo. Nangona kunjalo, isakhiwo esifunekayo ukuyiqonda kwi-motor ayinzima, ngoko ke ukusetyenziswa kobu buchwepheshe kubanzi. Ngokuqhelekileyo, i-hydro-generator enomthamo ongaphezulu kwe-megawatts ye-200 inokufumana inzuzo efanelekileyo yezoqoqosho ngokusebenzisa le teknoloji. Kwiiyunithi eziqala rhoqo (ezifana nezixhobo zombane ezimpontshwayo) okanye zifuna amandla okuvelisa kakhulu (kubandakanywa nokwandiswa kwamandla), kuya kubakho iziphumo ezingcono.
