RCD yog dab tsi?

Ib qho RCD, lossis cov khoom siv tam sim no, yog cov khoom siv hluav taws xob tseem ceeb uas siv los tiv thaiv hluav taws xob raug mob lossis tuag taus. Nws ua haujlwm los ntawm kev txiav tawm sai sai thaum muaj tib neeg lossis tsiaj nyob rau hauv kev sib cuag nrog nws.

RCD ua haujlwm li cas?

Nyob rau hauv ib tug sib npaug Circuit Court, tam sim no ntws los ntawm lub hwj chim qhov chaw los ntawm ib tug load (xws li ibEVcharger) thiab rov qab mus rau lub zog. Cov tam sim no nyob rau hauv cov xov hlau nyob thiab nruab nrab yog sib npaug, ua kom RCD kaw.

Yog ib tug neeg siv faultyEV Chargerlos yog cable thiab kov ib tug nyob conductor, cov tam sim no yuav ntws los ntawm lawv lub cev mus rau hauv av. Qhov no ua rau muaj qhov tsis sib xws ntawm qhov tam sim no nyob rau hauv tus neeg xyuas pib thiab cov neeg nruab nrab nruab nrab, vim qee qhov tam sim no tau hloov mus rau hauv av. RCD pom qhov tsis txaus ntseeg no thiab txiav tawm lub voj voog sai sai, yog li tiv thaiv tus neeg.

IEC 61851 STANDARD Thov EV CHARGER RCDs?

IEC 61851-1 tus qauv ntawmEV Charger, tsim los ntawm IEC technical committee, qhia txog cov kev cai dav dav rau kev muab hluav taws xob rau cov tsheb hluav taws xob thiab cov tsheb thauj khoom. Raws li IEC 61851-1, EV muab khoom siv (EV Charger) nrog lub qhov (socket)-qhov hluav taws xob lossis lub tsheb txuas rau AC siv (nyob rau hauv txoj kab nrog IEC 62196) yuav tsum muaj kev tiv thaiv tiv thaiv DC tam sim no. Tus qauv qhia tias cov kev ntsuas no yuav tsum muaj xws li:

* RCD hom B lossis
* RCD Hom A thiab cov cuab yeej tsim nyog uas ua kom muaj kev sib txuas ntawm cov khoom siv thaum muaj DC txhaum tam sim no siab dua 6 mA.
