Earth Leakage Circuit Breaker (ELCB)

motlakase

Sebakeng sa polokeho ea motlakase, e 'ngoe ea lisebelisoa tsa bohlokoa tse sebelisoang ke Earth Leakage Circuit Breaker (ELCB). Sesebediswa sena sa bohlokwa sa polokeho se etseditswe ho thibela ho tshoha le mello ya motlakase ka ho beha leihlo matla a phallang ka potolohong le ho e tima ha ho lemohuwa maqhubu a kotsi. Ho blog ena, re tla shebisisa hore na ELCB ke eng le hore na e re boloka re sireletsehile joang.

ELCB ke sesebelisoa sa polokeho se sebelisetsoang ho kenya lisebelisoa tsa motlakase tse nang le impedance e phahameng ea fatše ho qoba ho tsosoa ke motlakase. E sebetsa ka ho tsebahatsa li-voltage tse nyane tse khelohang ho tsoa ho lisebelisoa tsa motlakase tse koaletsoeng ka tšepe le ho sitisa potoloho ha ho fumanoa maqhubu a kotsi. Sepheo sa eona se seholo ke ho thibela batho le liphoofolo hore ba se ke ba lematsoa ke motlakase.

Molao-motheo oa ho sebetsa oa ELCB o bonolo haholo. E hlokomela ho se leka-lekane ha hona joale pakeng tsa li-conductors tsa mekhahlelo le mokhanni ea sa nke lehlakore. Ka tloaelo, hona joale ho phallang ka li-conductors tsa mekhahlelo le hona joale ho phallang ka ho se nke lehlakore ho lokela ho lekana. Leha ho le joalo, haeba phoso e etsahala, e kang ka lebaka la ho se sebetse hantle ha lithapo kapa ho kenya letsoho ho etsang hore metsi a lutlele fatše, ho tla ba le ho se leka-lekane. ELCB e lemoha ho se leka-lekane hona 'me ka potlako e khaola phepelo ea motlakase ho thibela tšenyo leha e le efe.

Ho na le mefuta e 'meli ea li-ELCBs: li-ELCB tse sebetsang ka matla le tse sebetsang hona joale. Li-ELCB tse tsamaisoang ke motlakase li sebetsa ka ho bapisa maqhubu a kenang le a tsoang, ha li-ELCB tse sebelisoang hona joale li sebelisa toroidal transformer ho lemoha ho se leka-lekane leha e le hofe ha hona joale ho phallang ka mekhahlelo le li-conductor tse sa nke lehlakore. Mefuta ena ka bobeli e lemoha le ho arabela ka katleho liphoso tse kotsi tsa motlakase.

Ke habohlokoa ho hlokomela hore li-ELCBs li fapane le li-circuits tsa setso, tse etselitsoeng ho sireletsa khahlanong le ho imeloa le li-circuits tse khutšoanyane. Le hoja li-circuit breakers li ka 'na tsa se ke tsa lemoha liphoso tsa boemo bo tlaase kamehla, li-ELCB li etselitsoe ka ho khetheha hore li arabele li-voltage tse nyenyane tse khelohileng le ho sireletsa khahlanong le ts'oaetso ea motlakase.

Ka kakaretso, "leakage circuit breaker" (ELCB) ke sesebelisoa sa bohlokoa sa tšireletso se phethang karolo ea bohlokoa ho thibela ho tsosoa ha motlakase le mollo oa motlakase. Ka ho shebella phallo ea hona joale le ho arabela ho se leka-lekaneng kapa phoso leha e le efe, ELCB e khona ho koala matla ka potlako le ho thibela kotsi leha e le efe e ka bang teng ho batho le liphoofolo. Ha re ntse re tsoela pele ho etelletsa pele polokeho ea lapeng le mosebetsing, ho bohlokoa ho utloisisa bohlokoa ba li-ELCB le kamoo li sebetsang kateng.
