Pholiso ea Vacuum Arc ea Vacuum Circuit Breaker
Vacuum e phahameng e na le matla a phahameng haholo a dielectric.Ka lefela hona joale arc e tima ka potlako haholo, 'me matla a dielectric a thehoa ka potlako haholo.Ho khutla hona ha matla a dielectric ke ka lebaka la tšepe e nang le mouoane e fumanehang ka har'a likhokahano e arohana ka potlako ka lebaka la ho se be teng ha limolek'hule tsa khase.Kamora tšitiso ea arc, matla a ho hlaphoheloa nakong ea li-microseconds tse seng kae tsa pele ke 1 kV/µs ea bobeli bakeng sa arc current ea 100A.
Ka lebaka la tšobotsi e boletsoeng ka holimo ea vacuum circuit breaker, e khona ho sebetsana le liphetoho tse matla tsa ho hlaphoheloa tse amanang le liphoso tsa nako e khutšoanyane ntle le bothata leha e le bofe.
Thepa ea thepa ea ho ikopanya
Thepa ea ho ikopanya ea vacuum circuit breaker e lokela ho ba le thepa e latelang.
Seqhoa sa Circuit Breaker se sebetsang
Ha phoso e etsahala tsamaisong, li-contacts tsa sehahi li tlosoa ka thōko 'me kahoo arc e ntlafatsoa pakeng tsa bona.Ha likhokahano tsa hona joale tse jereng li huloa ka thoko, mocheso oa likarolo tsa bona tse hokahanyang o phahame haholo ka lebaka la hore ionization e etsahala.Ka lebaka la ionization, sebaka sa ho kopana se tletse mouoane oa li-ion tse ntle tse ntšoang ho tloha linthong tsa ho kopana.
Potoloho ea tlhokomelo ea vacuum circuit breaker
Sekhechana sa potoloho ea vacuum se na le litšobotsi tsa ts'epo e phahameng, bophelo bo bolelele ba ts'ebeletso le potoloho ea nako e telele ea tlhokomelo le tokiso, empa ho ke ke ha fosahala hore sekhechana sa potoloho ea vacuum ha se hloke tlhokomelo.Potoloho ea tlhokomelo e lokela ho laoloa ka mokhoa o feto-fetohang ho ea ka melao e nepahetseng le ho kopantsoe le maemo a sebele a ts'ebetso.
1. Arc e tima ka setsing se tiisitsoeng, 'me arc le khase e chesang ha e hlahe.Joaloka karolo e ikemetseng, kamore ea ho tima arc e bonolo ho e kenya le ho e lokisa.
2. Tlhaloso ea ho kopana e nyenyane haholo, hangata e ka bang 10mm, e nang le matla a manyenyane a koalang, mochine o bonolo le bophelo bo bolelele ba tšebeletso.
3. Nako ea ho tima arc e khutšoanyane, motlakase oa arc o tlaase, matla a arc a nyenyane, tahlehelo ea ho kopana e nyenyane, 'me linako tsa ho senya li ngata.
