Ke eng eEarth Leakage Circuit Breaker?

Earth Leakage Circuit Breaker (ELCB) e etselitsoe ho bona le ho araba maqhubu a lutla a tsoang setsing sa motlakase ho ea fatše. Maqhubu ana a lutlang, leha a le manyane, a ka baka likotsi tse kholo, ho kenyeletsoa ho tsukutloa ha motlakase le mello ea motlakase. ELCB e hlokomela phapang pakeng tsa li-conductor tse sebetsang (tse phelang) le tse sa nke lehlakore tsa potoloho. Haeba ho na le ho se leka-lekane ho bonoang, ho bonts'a hore ho na le metsi a ntseng a lutla lefatšeng, ELCB e nka potoloho, e khaola phepelo ea motlakase ho thibela ho lutla ho hong le likotsi tse ka bang teng.

ELCB e sebetsa Joang?

Li-ELCB li sebetsa ho latela molao-motheo oa ho khetholla hona joale. Ba tsoela pele ho shebella hona joale ho phalla ka li-conductor tse sebetsang le tse sa nke lehlakore. Tlas'a maemo a tloaelehileng, hona joale ho phallang ho potoloha ka mokhanni ea sebetsang ho lokela ho lekana le hona joale ho khutla ka mokhanni ea sa nke lehlakore. Haeba ho na le ho se lumellane ho itseng, ho bontša hore metsi a lutla a phallang lefatšeng.

ELCB e na le transformer ea hona joale e bonang ho se leka-lekane hona. Ha motlakase o fapaneng o feta moeli o behiloeng esale pele, oo hangata e leng 30mA, ELCB e hlahisa mochine oa relay o hakollang potoloho, kahoo e emisa ho phalla ha hona joale le ho fokotsa kotsi ea ho tsosoa ke motlakase kapa mollo.

Mefuta ea Lefatše Leakage Circuit Breakers

Ho na le mefuta e 'meli ea mantlha ea li-ELCB: Voltage Earth Leakage Circuit Breakers (voltage ELCBs) le Current Earth Leakage Circuit Breakers (ELCBs ea hajoale), e tsejoang hape e le Residual Current Devices (RCDs).
