Njengombana siyazi, idivayisi yokuzivikela iragela phambili iyakwehlisa noma ifike ekupheleni kwempilo ngokuhamba kwesikhathi ngenxa yezintambo ezincane eziphindaphindiwe, ukuqhutshwa okunamandla okuqinile noma ukuqhubekela phambili okuqhubekayo. Futhi uma idivaysi yokuzivikela yokuphepha ihluleka, ingase idale isimo sesifunda esifushane futhi ibangele inkinga yokuphepha ohlelweni lwamandla. Ngakho-ke idivayisi efanele yokuvikelwa kwe-overcurrent iyadingeka ukuze isebenze ndawonye nedivayisi yokuvikela.
Kuvame ukuba nezinhlobo ezimbili zedivaysi yokuvikelwa kwe-overcurrent esetshenziselwa kanye ne-SPD ekuvikeleni isipele: i-circuit breaker ne-fuse. Ngakho-ke, yiziphi izinzuzo zabo ne-Cons ngokulandelanayo?
I-circuit breaker
Izinzuzo
- Ungasetshenziswa ngokuphindaphindiwe futhi ngaleyo ndlela unciphise izindleko zokugcina.
Okumbi
- Iba ne-voltage eyehla kakhulu lapho ubhekene ne-surge yamanje ngakho-ke izokwehlisa izinga lokuvikela le-SPD
Fuse
Izinzuzo
- Okuncane kakhulu kokungasebenzi kahle
- I-voltage engezansi ilahla okwamanje
- Umkhiqizo ngokwawo ubiza izindleko ezisebenzayo ikakhulukazi esimeni esifushane sesimo samanje samanje
Okumbi
- Ngemuva kokuthi isebenze, i-fuse kufanele ishintshwe futhi ngaleyo ndlela yande izindleko zesondlo
Ngakho-ke ekusebenzeni, kokubili amadivaysi asetshenziswa kuye ngokuthi isimo esithile.
