Chotsukira magetsi chotsalira (RCCB): choteteza chitetezo cha magetsi

Chotsukira dera chotsalira (RCCB): woyang'anira chitetezo chamagetsi

Zotsalira za magetsi ozungulira magetsi (RCCBs)ndi ngwazi zosayamikirika za chitetezo chamagetsi. Ndiwo mzere woyamba wodzitetezera ku ngozi zamagetsi, kuteteza anthu ndi katundu ku zoopsa zokhudzana ndi kulephera kwa magetsi. Munkhaniyi tikuphunzira mozama zomweMa RCCBKodi ndi ziti, momwe zimagwirira ntchito komanso chifukwa chake ndizofunikira kwambiri pa kukhazikitsa magetsi kulikonse.

Choyamba tiyeni timvetse mfundo zoyambira zaRCCBMwachidule,RCCBndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kuzindikira ndikuletsa zolakwika zamagetsi zotsalira kuti zisachitike. Kulephera kumeneku nthawi zambiri kumachitika chifukwa cha kulephera kwa insulation kapena kutuluka kwa magetsi ndipo kumatha kupha ngati sikudziwika. RCCB imayang'anira dera ndipo imatha kutseka magetsi mwachangu ngati alephera, zomwe zimathandiza kuchepetsa chiopsezo cha ngozi zamagetsi monga kugwedezeka kwa magetsi ndi moto.

Khalidwe lofunika laMa RCCBndi momwe amamvera mphamvu yamagetsi yotsalira. Imatha kuzindikira ngakhale kusalingana kochepa pakati pa mphamvu yamagetsi yamoyo ndi yapakati yomwe ikuyenda mu dera. Kuzindikira kumeneku ndikofunikira kwambiri popewa ngozi, chifukwa kumalolaRCCBkuti agwe mkati mwa ma milliseconds asanafike pamlingo woopsa. Mwa kuchita izi, ma RCCB amapereka mulingo wa chitetezo chomwe ma circuit breakers achikhalidwe sangachipeze.

Bungwe la RCCB lakwanitsa izi kudzera muukadaulo wapamwamba.RCCBPali chitoliro cha maginito chokhala ndi ma winding awiri osiyana: choyamba ndi chachiwiri. Kuzungulira koyamba kumanyamula magetsi a circuit, pomwe kuzungulira kwachiwiri kumawunika kusalingana pakati pa ma current amoyo ndi osalowerera. Ngati kusalingana kumeneku kupitirira malire omwe adakhazikitsidwa kale, RCCB imagunda ndikusokoneza mphamvu, kuonetsetsa kuti pali chitetezo.

Kuwonjezera pa kuzindikira mphamvu yotsalira, ma RCCB amaperekanso chitetezo cha short-circuit ndi overload. Kusinthasintha kumeneku kumawapangitsa kukhala gawo lofunikira la dongosolo lililonse lamagetsi. Mwa kuphatikiza ntchito zaRCCBNdi chotsukira magetsi chokhazikika, chitetezo chokwanira ku zolakwika zosiyanasiyana zamagetsi chingatsimikizidwe.

Ma RCCB nthawi zambiri amaikidwa mu switchboard yayikulu kapena koyambira kwa dera. Kuyika kumeneku kumaonetsetsa kuti dera lonselo ndi lotetezedwa, kuphatikizapo zida zonse ndi zida zina zotsika. Ndikofunikira kudziwa kuti kuti zikhale zotetezeka kwambiri, ma RCCB ayenera kuyesedwa ndi kusamalidwa nthawi zonse. Kuyesedwa nthawi zonse kumawonetsetsa kuti zidazo zili bwino komanso zimapitiliza kupereka chitetezo chogwira mtima.

Mwachidule,zotsalira za circuit breakers (RCCB)Amagwira ntchito yofunika kwambiri poonetsetsa kuti moyo ndi katundu wawo ndi otetezeka komanso kupewa ngozi zamagetsi. Chifukwa cha luso lawo lozindikira ndikupewa zolakwika zamagetsi, amapereka chitetezo chosayerekezeka ku kugwedezeka kwa magetsi ndi moto. Kuzindikira kwawo kuphatikiza ndi kuthekera kwawo kuteteza ku ma circuit afupi ndi kupitirira muyeso kumapangitsa kuti akhale gawo lofunikira pa kukhazikitsa magetsi kulikonse. Chofunika kwambiri chiyenera kuperekedwa pakukhazikitsa ndi kusamalira nthawi zonse magetsi.Ma RCCBkuonetsetsa kuti chitetezo chamagetsi chili pamlingo wapamwamba kwambiri. Kumbukirani,RCCBndiye mtetezi wathu wodalirika pankhani ya chitetezo chamagetsi.
