Iziphuli zesekethe ze-plug-inzizixhobo ezibalulekileyo zokuqinisekisa ukhuseleko lweesekethe zombane emakhayeni ethu nakwiindawo zokusebenza. Isebenza njengendlela yokukhusela ngokuvala ngokuzenzekelayo umbane xa kukho umbane omninzi okanye i-short circuit. Eli nqaku lijolise ekuboneleleni ngesishwankathelo esipheleleyo see-plug-in circuit breakers, imisebenzi yazo, iintlobo kunye neenzuzo.
Iziphuli zesekethe ze-plug-in, ezaziwa ngokubaiziphuli zesekethe ezincinci (i-MCB), zifakelwa lula kwaye zifakwe kwiiphaneli zombane. Yenzelwe ukukhusela iingcingo zombane kunye nezixhobo kumonakalo obangelwa ngumbane ogqithisileyo. Xa kuvela impazamo yombane, efana ne-short circuit okanye i-overload, i-circuit breaker ifumanisa imeko engaqhelekanga kwaye ikhawuleze iphazamise umbane, ithintele umonakalo ongakumbi okanye umlilo onokubakho.
Kukho iintlobo ngeentlobo zee-plug-in circuit breakers ezithengiswayo. Ezona zixhaphakileyo zii-single-pole circuit breakers, ii-double-pole circuit breakers, kunye nee-ground fault circuit interrupters (GFCI). Ii-single-pole circuit breakers zisetyenziswa kwii-120-volt circuits kwaye zikhusela ii-circuits ngazinye, ezifana nokukhanyisa kunye nee-universal receptacles. Ii-double-pole circuit breakers, kwelinye icala, zisetyenziselwa izixhobo ezinkulu kwaye zikhusela ii-240-volt circuits, ezifana neenkqubo zomoya kunye nezifudumezi zombane. Ii-GFCI zenzelwe ukukhusela kwiimpazamo zomhlaba kwaye zihlala zisetyenziswa kwiindawo ezimanzi ezifana neekhitshi kunye namagumbi okuhlambela.
Kukho iingenelo ezininzi zokusebenzisa i-plug-in circuit breaker. Okokuqala, zibonelela ngokhuseleko oluphezulu lombane ngokuthintela ubushushu obugqithisileyo kunye nemililo enokubakho. Zikhusela inkqubo yombane kunye nezixhobo zayo eziqhagamshelweyo ngokunqamla umbane kwi-circuit. Okwesibini, ii-plug-in circuit breakers kulula ukuzifaka nokuzitshintsha. Ngokungafaniyo nee-fuse zemveli ezifuna ukutshintshwa ngesandla xa zivuthuza, ii-circuit breakers zinokusetwa ngokutsha ngeswitshi elula emva kokuba impazamo ilungisiwe. Oku kusindisa ixesha kwaye kususa isidingo sokuthenga ii-fuse ezintsha rhoqo. Ukongeza, ii-plug-in circuit breakers zibonelela ngokulula kunye nokuguquguquka. Ngoyilo lwazo lwe-plug-in, zinokongezwa okanye zisuswe ngokulula ngaphandle kokufuna izixhobo ezizodwa okanye ubuchule bobuchwephesha.
Ukuqinisekisa ukusebenza kakuhle nokuthembeka kwe-plug-in circuit breaker, kubalulekile ukuyigcina isebenza kakuhle. Ukuhlolwa rhoqo kunye nokugcinwa kufuneka kwenziwe yingcali yombane eqeqeshiweyo ukuqinisekisa ukuba i-circuit breaker isebenza kakuhle. Kubalulekile nokuqaphela ukuba ii-plug-in circuit breakers zinomthamo omncinci. Ke ngoko, ii-circuit breakers kufuneka zibe nobukhulu obuchanekileyo ngokusekelwe kumthwalo wombane ezijoliswe kuwo ukuwukhusela. Ukulayisha kakhulu i-circuit breaker kunokubangela ukukhubeka rhoqo kunye nomonakalo onokubakho kwinkqubo yombane.
Ngamafutshane,i-plug-in circuit breakeryinxalenye ebalulekileyo yenkqubo yombane ebonelela ngokhuseleko kunye nokhuseleko kwiimpazamo zombane. Kulula ukuzifaka, ziguquguquka kwaye zilula, nto leyo eyenza zibe lolona khetho luphambili kwiizicelo zokuhlala kunye nezorhwebo. Ukugcinwa rhoqo kunye nobungakanani obuchanekileyo kubalulekile ekusebenzeni kakuhle kwee-plug-in circuit breakers. Ngokuqonda iimpawu kunye neenzuzo zayo, abanini bezindlu kunye neengcali banokuqinisekisa ukhuseleko lweenkqubo zabo zombane kwaye baphephe iingozi ezinokubakho.
