Ii-breaker yesekethe evuzayo(isixhobo sokukhusela ukuvuza) sisixhobo sokukhusela umbane esinokuwucima umbane ngexesha xa izixhobo zombane zingasebenzi kwaye sithintele ukwenzeka kokubetheka kombane.i-residual current breakerikakhulu yenziwe ngolungelelwaniso lwangaphakathi kunye nolwakhiwo lwangaphandle.
Indlela yangaphakathi yenziwe ngeyunithi yolawulo lwe-elektroniki, isixhobo sokumisa esingathathi cala, ukujija kwesibini, uqhagamshelwano oluhambayo kunye noqhagamshelwano olungashukumiyo, njl.
Isakhiwo sangaphandle senziwe ngeqokobhe, iyunithi yolawulo lwe-elektroniki, isixhobo sokudlulisa umbane kunye nesixhobo sokumisa umhlaba, kwaye sineempawu zomthamo omncinci, ubunzima obulula kunye nokufakelwa okulula. Xa sidityaniswe nesithinteli sokuvuza, asinakukwazi nje kuphela ukwenza umsebenzi wokukhusela wesikhuseli esipheleleyo kumgca, kodwa sikwanokwenza umsebenzi wokukhusela weluphu yesigaba esinye kunye nezixhobo zesigaba esinye, kwaye sinokusetyenziselwa ukukhusela umthwalo wesigaba esinye kwiluphu nganye yesebe.Isixhobo sokukhusela ukuvuzasisixhobo sokukhusela umbane esibanzi esinenkqubo yoqhagamshelwano njengesiziko, ulungelelwaniso loqhagamshelwano kunye nexesha lokusebenza njengeeparameter. Sinokukhusela ukhuseleko lomntu, sikhusele izixhobo zombane, sikhusele inkqubo yombane kunye nepropati yesizwe ekulahlekelweni, kwaye sinokunqumla ngokukhawuleza umbane xa kwenzeka ingozi.
Kukho iintlobo ezintathu zezikhuseli zokuvuza: Izikhuseli zokuvuza zeKlasi I ziyakwazi ukunqumla umbane wepali olungileyo nongalunganga ongena-voltage ukuya emhlabeni; Izikhuseli zokuvuza zeKlasi II ziyakwazi ukunqumla ucingo lomlilo, ucingo olungenanto, ucingo lomhlaba kunye nolunye unikezelo lwamandla olujikelezayo olungenammiselo; Izikhuseli zokuvuza zeKlasi III ziyakwazi ukunqumla umbane ngomsebenzi wokukhusela isekethe emfutshane. Uhlobo ngalunye lwesikhuseli sokuvuza lunemisebenzi yalo: Udidi I (olusetyenziswa rhoqo) lusetyenziswa kakhulu ekunxibelelaneni ngokuthe ngqo nomonakalo wombane; Udidi II (osetyenziswa rhoqo) lusetyenziswa kakhulu ekunxibelelaneni ngokuthe ngqo nomonakalo wombane; kwaye Udidi III (osetyenziswa rhoqo) lusetyenziswa kakhulu ekuthinteleni iintlantsi kunye nee-arcs ezibangelwa kukonakala kwe-insulation yezixhobo kunye nemigca.
Iimpawui-tics
1, Ukhuseleko lomthwalo ogqithisileyo kunye nokhuseleko lwesekethe emfutshane lungenziwa ngaphakathi koluhlu oluthile, kwaye umbane ungalawulwa ngeqhosha elikwiphaneli ngaphakathi koluhlu oluthile.
2. Inee-terminals ezintathu, ezidityaniswe ngokulandelelanayo nomgca wesigaba sangoku otshintshanayo we-220V kunye nomgca womhlaba wokukhusela (umgca we-N), ngoko ke umkhuseli wokuvuza unokukhusela imigca emithathu ngaxeshanye.
3, Ixesha lokusebenza liza kumiselwa ngokwexesha elichazwe kwimigaqo, kwaye aliyi kuphambuka kwixesha lokusebenza ngenxa yokuguquguquka kwevolthi okanye ukukhululeka kwesixhumi somqhubi, kwaye liza kuba ngumkhuseli wokuvuza "ongasebenziyo" wokwenyani.
4, Xa kukho i-short circuit kumgca, umgca ngokwawo awuyi kusebenza; uya kukhubeka kuphela xa kukho i-fault current kumgca, kwaye ukuba kukho i-short circuits ezingaphezu kwesibini kumgca, uya kukhubeka.
5, Ingasetyenziswa ngokuzimeleyo njengesixhobo sokukhusela ukhuseleko okanye kunye nezinye iisekethe zokukhusela.
