Kumvetsetsa kufunikira kwa RCD Earth leakage circuit breaker

M'dziko lachitetezo chamagetsi, zotsalira za RCD zotsalira zimagwira ntchito yofunika kwambiri poteteza anthu ndi katundu ku ngozi zamagetsi.Zidazi zidapangidwa kuti zizitha kuyang'anira momwe zingwe zikuyenda komanso zosalowerera ndale, ndipo ngati pali kusalinganika, zimadutsa ndikudula magetsi.Chitsanzo chimodzi chotere ndiChithunzi cha JCR4-125, yomwe imadziwika kuti ndi yodalirika komanso yothandiza popewa ngozi zamagetsi.

TheChithunzi cha JCR4-125imayesa zomwe zikuyenda mu zingwe zamoyo ndi zopanda ndale, ndipo ngati pali kusalinganika, komwe kukuyenda padziko lapansi pamwamba pa kukhudzidwa kwa RCD, RCD idzayenda ndikudula.Izi ndizofunikira popewa kugwedezeka kwamagetsi ndi moto womwe umabwera chifukwa cha zolakwika, mawaya owonongeka, kapena zovuta zina zamagetsi.Pozindikira mwachangu ndikusokoneza mafunde achilendo, ma RCD amapereka chitetezo chowonjezera ku zoopsa zamagetsi, kuwapangitsa kukhala gawo lofunikira pamagetsi aliwonse.

Chimodzi mwazabwino zazikulu za RCDs ndikutha kupewa kugwedezeka kwamagetsi.Munthu akakumana ndi kondakitala wamagetsi wamoyo, madzi akuyenda m'thupi mwake amatha kuvulaza kwambiri kapena kufa.Ma RCD amapangidwa makamaka kuti azindikire mafunde achilendo ngati awa ndikuchotsa magetsi mkati mwa ma milliseconds, kuchepetsa kwambiri chiwopsezo cha kugwedezeka kwamagetsi.Izi ndizofunikira makamaka m'malo omwe zida zamagetsi zimagwiritsidwa ntchito pafupi ndi madzi, monga mabafa, makhitchini, ndi malo akunja.

Kuphatikiza pa kuteteza kugwedezeka kwamagetsi, ma RCD amakhalanso ndi gawo lofunika kwambiri poletsa moto wamagetsi.Kuwonongeka kwamagetsi kumachitika, monga kufupikitsa kwafupipafupi kapena kulephera kwamphamvu, mafunde osadziwika bwino amatha kudutsa mu waya, zomwe zimapangitsa kutentha kwambiri komanso kuthekera kwamoto kuyaka.Pozindikira mafunde achilendowa ndikutseka magetsi, ma RCD amathandizira kuchepetsa kuopsa kwa moto wamagetsi, kupereka mtendere wamumtima kwa eni nyumba ndi okhalamo.

Kuphatikiza apo, ma RCD ndi ofunikira pakuwonetsetsa kuti akutsatira malamulo ndi miyezo yachitetezo chamagetsi.M'madera ambiri, kukhazikitsa RCD kumayendetsedwa ndi mitundu ina ya mabwalo amagetsi, makamaka omwe akutumikira madera omwe ali ndi chiopsezo chachikulu cha kugwedezeka kwa magetsi kapena moto.Momwemonso, ma RCD si njira yokhayo yodzitetezera komanso yovomerezeka mwalamulo nthawi zambiri, zomwe zimawapangitsa kukhala osakambitsirana pakupanga ndi kukhazikitsa kwamagetsi.

Ponseponse, zotsalira za RCD zotsalira zapano monga JCR4-125 ndizofunikira kwambiri pachitetezo chamagetsi, zomwe zimapereka chitetezo chodalirika komanso chothandiza pakuwotcha kwamagetsi ndi moto.Kaya m'malo okhala, malonda, kapena mafakitale, ma RCD amagwira ntchito yofunika kwambiri pochepetsa kuopsa kwa magetsi, kuwonetsetsa kuti akutsatira malamulo, komanso kuteteza anthu ndi katundu ku zoopsa za magetsi olakwika.Pamene ukadaulo ukupitilirabe patsogolo, ma RCD mosakayikira adzakhalabe chitetezo chofunikira m'masiku amakono.
