Chii chinonzi RCBOs uye Anosiyana Sei kubva kuRCDs?

Kana iwe ukashanda nemidziyo yemagetsi kana muindasitiri yekuvaka, unogona kunge wakasangana neshokoRCBO. Asi chii chaizvo maRCBOs, uye akasiyana sei neRCDs? Mune ino blog, tichaongorora mashandiro eRCBOs toaenzanisa neRCDs kuti ikubatsire kunzwisisa mabasa awo akasiyana mukuchengetedza magetsi.

Izwi rekuti RCBO rinomirira Residual Current Breaker ine Over-Current dziviriro. RCBOs midziyo inosanganisa dziviriro kubva kumvura inodonha pasi pamwe nepamusoro pemvura, senge yakawandisa kana pfupi-circuit. Izvi zvinoreva kuti maRCBO anopa dziviriro mbiri, zvichiita kuti ive chinhu chakakosha mumagetsi ekuchengetedza masisitimu.

Pakutanga kuona, basa reRCBOinogona kunzwika seyakafanana neyeRCD (Residual Current Device), sezvo ese ari maviri anopa dziviriro kubva kune yakawandisa uye pfupi-circuit. Nekudaro, pane misiyano mikuru pakati pezviviri izvo zvinozvisiyanisa maererano nekushandisa kwavo uye kushanda.

Mumwe wemisiyano mikuru pakati peRCD neRCBO kugona kwavo kwakasiyana. Nepo RCD yakagadzirirwa kupa dziviriro kubva kumvura inodonha pasi uye njodzi yekuvhunduka kwemagetsi, RCBO inoenda rimwe danho nekupa dziviriro kubva kune yakawandisa. Izvi zvinoita kuti RCBOs ive inogadzirisa uye yakazara mhinduro yekuchengetedza magetsi, kunyanya munzvimbo dzine njodzi yekupfuura.

Imwe mutsauko wakakosha pakati peRCBOs neRCDs ndeyekuisa kwavo uye wiring zvinodiwa. MaRCBO akagadzirwa kuti aiswe nenzira inobvumira masekete ega ega kuti adzivirirwe neawo akazvipira mudziyo. Izvi zvinoreva kuti kana paine chikanganiso kana kuremerwa, dunhu rakakanganiswa chete ndiro rinodzorwa, zvichibvumira mamwe maseketi kuti arambe achishanda. Kune rimwe divi, maRCD anowanzo kuisirwa pabhodhi rekugovera uye anopa dziviriro kune akawanda maseketi, achiita kuti ave akakodzera kuchengetedzwa kwakakura asi kushoma kuenderana nezvinodiwa zvedunhu rega.

Mukutaura, maRCBO anonyanya kubatsira munzvimbo umo kuenderera kwemagetsi kwakakosha, senge mune zvekutengesa kana maindasitiri. Nekupa dziviriro yakanangwa yemasekete ega ega, maRCBO anobatsira kuderedza nguva yekudzikira uye kukanganisa kunokonzerwa nekukanganisa kwemagetsi, zvichizopa kune imwe yakavimbika uye inoshanda hurongwa hwemagetsi.

Mukupedzisa, maRCBO anopa mwero wepamusoro wedziviriro kana uchienzaniswa neRCDs nekubatanidza kudonha kwepasi uye kuchengetedzwa kwepamusoro mumudziyo mumwe chete. Kugona kwavo kupa kuchengetedzwa kwakanangidzirwa kune ega masekete kunoita kuti vave chinhu chakakosha mumagetsi ekuchengetedza masisitimu, kunyanya munzvimbo dzine njodzi yekupfuura. Kunzwisisa mabasa akasarudzika uye misiyano pakati peRCBOs neRCDs kwakakosha pakuita shuwa kushandiswa kwemagetsi matanho ekuchengetedza magetsi munzvimbo dzakasiyana siyana.
