Isakhiwo nokuvikelwa kwama-high-voltage pole-mounted circuit breakers

Iiswishi efakwe ngesigxoboluhlobo lweswishi yokuphepha efakwe ezigxotsheni zensiza ukuze kuqinisekiswe ukuphepha kukagesi. Umsebenzi wayo oyinhloko ukuhlukanisa i-voltage ephezulu yesekethe. Amaswishi afakwe ngegxolo anomehluko omkhulu ngokuya ngokusebenza, ukwakheka, nezimo zohlelo lokusebenza. Kusistimu yamandla, ngayinye idlala indima eyingqayizivele futhi ngokuhlanganyela igcina ukuphepha nokusebenza okuzinzile kwegridi yamandla.

Isiphakeli sesekethe esifakwe kwikholomu kanye neswishi yokulayisha

Iswishi yokulayisha efakwe esigxotsheni inemisebenzi yokuphula umthwalo wamanje kanye nokuvala isiyingi esifushane wamanje, kodwa ayikwazi ukunqamula i-short-circuit current. Isetshenziswa kakhulu ekuhlukaniseni umugqa.

I-breaker-mounted circuit breaker ingavala, iphathe futhi ivule i-current evamile yesekethe yokusebenza. Ingakwazi futhi ukuvala, ukuthwala nokuvula i-short-circuit current eshiwo ngesikhathi esinqunyiwe. Ingasetshenziswa njengesivikelo esiyinhloko somugqa futhi isetshenziswa ikakhulukazi ekushintsheni kwamagatsha amakhulu. Umthamo wayo wokuvula unamandla futhi inani lokuvula nokuvala okulandelanayo likhulu.

Indlela yokusebenza

I-switch switch isetshenziswa ngesandla futhi idinga ukungenelela komuntu ukuvula noma ukuvala isekethe.

I-circuit breaker iyisisetshenziswa esisebenza ngokuzenzakalela. Uma kune-overload noma isifunda esifushane kumjikelezo, i-circuit breaker izohamba ngokuzenzakalelayo futhi inqamule yamanje.

Ukumelana nokuhlukaniswa nemisebenzi yokuvikela

Amaswishi okulayisha ngokuvamile anomthamo ophansi wokuphuka futhi afanele imithwalo emincane nezimo ezingalayishi kakhulu. Zisetshenziswa kakhulu ukulawula ukuvulwa nokuvalwa kwamasekethe. Kodwa-ke, ngokuvamile azinakho ukuvikelwa kokulayishwa okuningi noma imisebenzi yokuvikela isiyingi esifushane ngamaphutha afana nokugcwala ngokweqile namasekhethi amafushane.

I-circuit breaker inamandla okuphuka aphezulu futhi ingakwazi ukuphatha imisinga emikhulu kanye namaphutha amakhulu kakhulu. Ayinqamuli nje kuphela isekethe kodwa futhi inokuvikelwa kokulayishwa ngokweqile kanye nemisebenzi yokuvikela isiyingi esifushane, ekwazi ukubona ngokushesha futhi inqamule umsinga ongalungile.
