Umehluko Phakathi Kokushintsha Komthwalo We-Voltage Ephakeme Ne-High Voltage Circuit Breaker

Iswishi yomthwalo we-voltage ephezulu iwuhlobo lomsebenzi phakathi kwe-high voltage circuit breaker kanye ne-high voltage isolation switch, iswishi yomthwalo we-voltage ephezulu kanye ne-high voltage fuse ivame ukusetshenziswa ochungechungeni; Isetshenziselwa ukulawula ama-transformer kagesi. Iswishi yomthwalo we-voltage ephezulu inedivayisi elula yokucisha i-arc, ngakho ingacima i-load current ethile kanye ne-overload current. Kodwa-ke, ayikwazi ukuxhuma i-short circuit current, ngakho-ke ivame ukusetshenziswa ochungechungeni ne-high voltage fuse, ne-fuse yokuvikela i-short circuit.

Izincazelo ezahlukene:

Kodwa-ke, ayikwazi ukuxhuma i-short circuit current, ngakho-ke ivame ukusetshenziswa ochungechungeni ne-high voltage fuse, ne-fuse yokuvikela i-short circuit.

I-circuit breaker ibhekisela kudivayisi yokushintsha engacima, ithwale futhi ivale ugesi ngaphansi kwezimo zesekethe ezijwayelekile futhi icishe, ithwale futhi ivale ugesi ngaphansi kwezimo zesekethe ezingavamile ngaphakathi kwesikhathi esibekiwe. Ama-circuit breaker ahlukaniswe ngama-circuit breaker ane-voltage ephezulu kanye nama-circuit breaker ane-voltage ephansi ngokwebanga lokusetshenziswa kwawo. Ukuhlukaniswa kwemingcele ye-high-voltage kanye ne-low-voltage akucaci. Ngokuvamile, lawo angaphezu kwe-3kV abizwa ngokuthi imishini ye-high-voltage.

Imisebenzi ehlukene:

Iswishi yomthwalo we-high-voltage ifaneleka ohlelweni lwamandla lwe-AC 10KV, 50HZ olunezigaba ezintathu, noma ngesethi ephelele yemishini yokusabalalisa kanye neswishi yenethiwekhi yendandatho, isiteshi esincane esihlanganisiwe kanye nokunye ukusetshenziswa okusekelayo, okusetshenziswa kabanzi kumaphrojekthi wokwakha nokuguqula inethiwekhi yesizinda, amabhizinisi ezimboni kanye nezimayini, izakhiwo eziphakeme kanye nezindawo zomphakathi, zingasetshenziswa njengokunikezwa kwamandla noma i-terminal yenethiwekhi yendandatho, zidlala indima yokusabalalisa amandla, ukulawula nokuvikela. Inezinzuzo zomthamo omkhulu wokuphuka, ephephile futhi ethembekile, impilo kagesi ende, ukusebenza njalo, isakhiwo esincane, usayizi omncane, isisindo esincane, futhi ngokuyisisekelo asikho isidingo sokulungiswa. Ngomshini wamandla ongasebenzi, ugesi ogcwele ngokweqile. Ingaphula ugesi wesifunda esifushane futhi ivimbele imishini ukuthi isebenze ngaphandle kwesigaba. Iswishi inokuqhekeka okusobala kokuhlukaniswa. Ifakwe umshini wentwasahlobo kagesi weswishi yokumisa onekhono lokuvala, ongalawulwa kude nakude.

Ama-circuit breaker angasetshenziswa ukusabalalisa amandla kagesi, ukuqala ama-motor angenawo ugesi njalo, ukuvikela izintambo zikagesi nama-motor, futhi anqume ngokuzenzakalelayo i-circuit uma enezinkinga ezinkulu zokulayisha ngokweqile, i-short circuit kanye ne-undervoltage. Imisebenzi yawo ifana nokuhlanganiswa kwe-fusing switch kanye ne-over and under thermal relay. Futhi ngokuvamile asikho isidingo sokushintsha izingxenye ngemva kokuqeda i-fault current. Njengamanje, isetshenziswe kabanzi.
