Mfundo 4 zomwe muyenera kuziganizira mukamagwiritsira ntchito RCBO

Ponena za chitetezo chamagetsi, kufunika kogwiritsa ntchitoRCBO (Chotsalira cha Circuit Breaker Chotsalira ndi Chitetezo cha Overcurrent) sizingatheke kupitirira muyeso. Chipangizo chofunikira ichi chapangidwa kuti chiteteze antchito ku kugunda kwa magetsi ngati chipangizocho chalephera kutuluka, kuonetsetsa kuti ali otetezeka m'nyumba ndi m'malo amalonda. Ndi zinthu zake zodzaza ndi zinthu zambiri komanso zoteteza ma circuit afupiafupi, ma RCBO ndi zinthu zofunika kwambiri mu dongosolo lililonse lamagetsi. Komabe, pali mfundo zingapo zofunika kukumbukira mukamagwiritsa ntchito RCBO kuti muwonetsetse kuti ikugwira ntchito bwino komanso ikugwira ntchito bwino.

Choyamba, ndikofunikira kulabadira mtengo wamagetsi otsala a RCBO. Pamene choteteza magetsi otsala chiyikidwa pakati pa chitetezo chathunthu ndi chitetezo chomaliza, mtengo wake wamagetsi otsala uyenera kukhala mkati mwa malire a zoteteza zamagetsi zotsalira zapamwamba ndi zotsika. Kusiyana kwa masitepe nthawi zambiri kuyenera kukhala pakati pa nthawi 1.2 ndi 2.5 kuti zitsimikizire kuti RCBO ikugwira ntchito bwino komanso moyenera mkati mwa makina amagetsi.

Kuwonjezera pa mtengo wotsalira wamagetsi ogwiritsidwa ntchito, ndikofunikiranso kuganizira kuchuluka kwa mphamvu yotsalira yogwiritsidwa ntchito yogwiritsidwa ntchito pa chitetezo chonse. Mu nyengo yopanda mvula, mphamvu yotsalira yogwiritsidwa ntchito yogwiritsidwa ntchito siyenera kupitirira 75-100mA, ndipo mu nyengo yamvula, siyenera kupitirira 200-300mA. Pa ntchito zapakhomo, mtengo wogwiritsira ntchito wa chotetezera mphamvu yotsalira yogwiritsidwa ntchito suyenera kupitirira 30mA kuti upereke chitetezo cholumikizana mwachindunji kwa anthu. Kuphatikiza apo, RCBO ikagwiritsidwa ntchito pazida zamagetsi zam'manja ndi zida zamagetsi zakanthawi, mtengo wake wogwiritsira ntchito uyeneranso kukhala 30mA.

Mfundo ina yofunika kuganizira mukamagwiritsa ntchito RCBO ndi kukhazikitsa bwino ndi kuyika pansi kwa zida. Pofuna kuteteza ma gridi amphamvu otsika mphamvu, malo osasunthika a transformer ayenera kulumikizidwa mwachindunji ndi nthaka. Ndikofunikira kuonetsetsa kuti gridi yosasunthika ya gridi siili pansi kawiri ndipo imasunga mulingo wofanana wa insulation monga ma phase conductors. Kuphatikiza apo, njira yokhazikitsira yotsalira ya residual current action protector iyenera kuletsa mzere wosasunthika ndi mzere wa gawo kuti zisagawidwe ndi ma circuits ena kuti zitsimikizire kuti RCBO ikugwira ntchito bwino.

Pomaliza, kugawa katundu wamagetsi kuyenera kuganiziridwa mosamala pogwiritsa ntchito RCBO, makamaka katundu wa gawo limodzi. Ndikofunikira kugawa magetsi mofanana ndi katundu wina wamagetsi wa gawo limodzi pamizere yamagetsi ya magawo atatu. Ngati kusiyana kuli kwakukulu, kusintha kuyenera kupangidwa kuti mafunde otuluka a gawo lililonse akhale ofanana kuti zitsimikizire kuti RCBO ikugwira ntchito bwino kwambiri. Kuphatikiza apo, pamene mizere yamagetsi otsika ndi mizere ya malo, magawo atatuwo ayenera kukhala ofanana kutalika kuti apereke kugawa bwino kwa katundu wamagetsi.

Mwachidule, kugwiritsa ntchito bwino ma RCBO ndikofunikira kwambiri pa chitetezo chamagetsi. Mwa kusamala kwambiri za mtengo wotsalira wamagetsi, mphamvu yotsalira yotsalira yogwiritsidwa ntchito, kukhazikitsa ndi kuyika pansi, komanso kugawa katundu wamagetsi, anthu amatha kuwonetsetsa kuti RCBO ikugwira ntchito bwino kwambiri mumakina awo amagetsi. Popeza ali ndi mphamvu zoteteza ku kugwedezeka kwamagetsi ndi kulephera kwa zida, ma RCBO ndi gawo lofunikira kwambiri pakusunga zomangamanga zamagetsi zotetezeka komanso zodalirika.
