Chidule cha Mitundu ya RCD

Zida Zotsalira Zamakono (RCDs) ndizofunikira zotetezera zomwe zimapangidwira kuti ziteteze kugwedezeka kwa magetsi ndi zoopsa zamoto poyika magetsi. Amayang'anira kuchuluka kwa mphamvu zamagetsi zomwe zimalowa ndikutuluka m'derali, ndipo ngati awona kusiyana, amadula msanga mphamvu kuti asavulaze. Pali mitundu iwiri ikuluikulu ya ma RCD: Type A ndi Type B, iliyonse ili ndi mawonekedwe ake enieni komanso momwe amagwirira ntchito.

Lembani A RCDs
Ma RCD a Type A ndi omwe amapezeka kwambiri ndipo amapangidwa kuti aziteteza ku AC sinusoidal, pulsating DC, ndi mafunde otsalira a DC. Ndioyenera kugwiritsidwa ntchito m'malo ambiri okhalamo komanso malonda omwe magetsi amakhala olunjika, ndipo chiopsezo chokumana ndi mafunde osakhala a sinusoidal kapena pulsating ndi otsika.
Chimodzi mwazinthu zazikulu zamtundu wa A RCDs ndikutha kuzindikira ndikuyankha mafunde otsalira a DC, omwe nthawi zambiri amapangidwa ndi zida zamagetsi monga makompyuta, ma TV, ndi kuyatsa kwa LED. Izi zimawapangitsa kukhala abwino kuti azigwiritsidwa ntchito m'makhazikitsidwe amakono amagetsi pomwe zida zotere ndizofala.

Lembani B RCDs
Ma RCD amtundu wa B amapereka chitetezo chokwanira kwambiri poyerekeza ndi zida za Type A. Kuphatikiza pakupereka chitetezo ku AC sinusoidal, pulsating DC, ndi mafunde otsalira a DC ngati Type A RCDs, amaperekanso chitetezo ku mafunde otsalira a DC. Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo omwe chiwopsezo chokumana ndi mafunde a DC chimakhala chokwera, monga m'mafakitale, makhazikitsidwe a photovoltaic (solar power), ndi malo opangira magalimoto amagetsi.
Kuthekera kwa ma RCD a Type B kuti azindikire ndikuyankha mafunde otsalira a DC ndikofunikira pakuwonetsetsa chitetezo chamagetsi omwe amagwiritsa ntchito magetsi a DC. Popanda chitetezo ichi, pali chiopsezo cha kugwedezeka kwa magetsi kapena moto, makamaka mu machitidwe omwe amadalira kwambiri mphamvu za DC, monga ma solar panels ndi makina osungira mabatire.

Kusankha RCD Yoyenera
Posankha RCD pa pulogalamu inayake, ndikofunikira kuganizira zofunikira ndi zoopsa zomwe zimagwirizanitsidwa ndi kukhazikitsa. Ma RCD a Type A ndi oyenera malo ambiri okhalamo komanso malonda pomwe chiopsezo chokumana ndi mafunde osakhala a sinusoidal kapena pulsating ndi otsika. Komabe, m'malo omwe muli pachiwopsezo chachikulu chokumana ndi mafunde a DC, monga poyika magetsi a mafakitale kapena dzuwa, ma RCD amtundu wa B amalimbikitsidwa kuti apereke chitetezo chapamwamba kwambiri.

Ma RCD a Type A ndi Type B onse ndi zida zofunika zotetezera zomwe zimapangidwira kuti ziteteze ku kugwedezeka kwamagetsi ndi zoopsa zamoto pakuyika magetsi. Ngakhale ma RCD a Type A ndi oyenera kugwiritsa ntchito nyumba zambiri komanso zamalonda, ma RCD amtundu wa B amapereka chitetezo chokwanira ndipo amalimbikitsidwa m'malo omwe chiopsezo chokumana ndi mafunde a DC chimakhala chokwera.
Ngati mukufuna kudziwa zambiri za izi, chonde omasuka kulankhula nafe.
