Intshayelelo yeSwitshi yokuPhumla uMthwalo ye-FLN48-12

Iswitshi yeLoadbreakifanelekile kwi-AC 50Hz yesigaba esithathu, umbane wenethiwekhi yeringi ye-12kV okanye inkqubo yombane wemitha emibini, esetyenziselwa ukutshintsha nokutshintsha i-load current kunye ne-overload current, kwaye ingasetyenziselwa ukutshintsha nokutshintsha imigca emide engenamthwalo. Ii-transformers ezingenamthwalo kunye neebhanki ze-capacitor, njl. Indibaniselwano yochungechunge lwe-load switch kunye ne-current-limiting fuse ingasetyenziswa endaweni ye-circuit breaker. Oko kukuthi, i-load switch inoxanduva lokuvala nokuphula i-load currents ezahlukeneyo, kwaye i-current-limiting fuse inoxanduva lokwaphula i-overload current enkulu kunye ne-short-circuit current.

1. Iimpawu: ukwaphuka kabini, izitishi ezintathu, uqhagamshelo olujikelezayo olushukumayo.
2. Ukusebenza kakuhle kobushushu. Iswitshi yomthwalo ivalwe ngamaqokobhe aphezulu nasezantsi enziwe nge-epoxy resin, egcwele igesi ye-SF6 yoxinzelelo lwe-0.045mpa, kwaye inkqubo yesekethe ephambili kunye nesekethe yokumisa zonke zibekwe kwiqokobhe.
3. Ukusebenza kakuhle kokhuseleko. Ukuba kukho i-arc yangaphakathi, kukho indawo ebuthathaka yesakhiwo ngasemva kweqokobhe, eya kuhlanjwa, emva koko ivalvu yokukhulula i-arc kwikhabhinethi iya kuhlanjwa kwaye umoya oxinzelelweyo uya kuqondiswa ngaphandle kwekhabhinethi.
4. Ukusebenza ngesandla kunye nombane kunokwenzeka, kwaye ukusebenza kulula kwaye kuthembekile.
Ufakelo oludibeneyo lwezigaba ezintathu, ukuphindaphinda okuhle, iindawo ezimbalwa, ukulungiswa nokufakelwa okulula, kulula kwaye kulula. Akukho kugcinwa kwaye ubomi buhlala ixesha elide.
