Isihloko: Qonda izinzuzo kanye nokusetshenziswa kweAma-fuse ochungechunge lwe-NH
ukwethula
Emkhakheni wobunjiniyela kagesi, ukukhetha izingxenye ezifanele zesicelo esithile kubalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zikagesi. Uma kukhulunywa ngokuvikelwa kwe-fuse, ama-fuse ochungechunge lwe-NH avelele njengenye yezinketho eziguquguqukayo nezithembekile kakhulu emakethe. Kule bhulogi, sizohlola imininingwane yeAma-fuse ochungechunge lwe-NH, xoxa ngezinzuzo zazo kanye nezicelo zazo, futhi ufunde ukuthi kungani zinconywa kakhulu onjiniyela emhlabeni jikelele.
Isigaba 1: YiniAma-fuse ochungechunge lwe-NH?
Ama-fuse ochungechunge lwe-NHama-fuse asebenza kahle kakhulu, aphansi kagesi aklanyelwe ukuhlinzeka ngokuvikelwa kwesekethe okuthembekile kuma-overcurrent kanye nama-short circuits. Igama elithi “NH” limelela elithi “Niederspannungs-Hochleistungssicherung”, okuyigama lesiJalimane elihunyushwa ngokuthi “i-low voltage high performance fuse”. Lawa ma-fuse avame ukusetshenziswa ezinhlelweni zokusabalalisa amandla zezigaba ezintathu, ikakhulukazi ezisetshenziswayo lapho ukuvikelwa kwemoto kubalulekile khona.
Isigaba sesibili: izinzuzo zeAma-fuse ochungechunge lwe-NH
Ama-fuse ochungechunge lwe-NHinikeza izinzuzo eziningana ngaphezu kwama-fuse afanayo. Okokuqala, lawa ma-fuse anamandla amahle kakhulu okuphuka, okusho ukuthi angaphazamisa ngokuthembekile imisinga yamaphutha aphezulu. Lesi sici siqinisekisa ukuthi i-fuse ivula isekethe ngokushesha, ivimbele umonakalo wemishini kanye nezingozi zikagesi ezingaba khona. Ngaphezu kwalokho, ama-fuse ochungechunge lwe-NH aziwa ngokumelana kwawo okuphezulu kwe-short-circuit kanye nokumelana nokushisa, okusiza ukwandisa impilo yawo yesevisi nokuthuthukisa ukuqina.
Ngaphezu kwalokho, usayizi omncane weAma-fuse ochungechunge lwe-NHkusindisa isikhala esibalulekile kumakhabethe kagesi. Lokhu kubaluleke kakhulu ekusetshenzisweni lapho isikhala silinganiselwe. Ngaphezu kwalokho, ukulingana okunembile kwala ma-fuse kuqinisekisa ukusebenza okuthembekile futhi kunciphisa ingozi yokukhubeka ngengozi, ngaleyo ndlela kwandisa ukusebenza kahle kanye nokuphepha kwesistimu kagesi.
Into yesithathu: ukusetshenziswa kweAma-fuse ochungechunge lwe-NH
Ama-fuse ochungechunge lwe-NHzisetshenziswa kabanzi ezimbonini ezahlukahlukene kanye nezicelo ngenxa yezici zazo zokusebenza ezinhle kakhulu. Zivame ukusetshenziswa ezikhungweni zokulawula izimoto (ama-MCC) ukuvikela izinjini kanye nezifunda zazo zokulawula. Lawa ma-fuse adlala indima ebalulekile ekuvikeleni izinjini ezimweni zokusebenzisa ngokweqile ezibangelwa amaphutha noma ukwehluleka kwemishini.
Ama-fuse ochungechunge lwe-NH asetshenziswa nasezinhlelweni zikagesi ezingaphazamiseki (i-UPS) ukuze ahlinzeke ngokuvikelwa okuthembekile kwemithwalo ebalulekile njengezikhungo zedatha, izibhedlela nezinye izinhlelo zokusebenza ezibucayi. Izilinganiso zamanje zamaphutha aphezulu kanye nesikhathi sokuphendula okusheshayo salezi fuse zizenza zilungele ukuqinisekisa amandla angaphazanyiswa kanye nokunciphisa isikhathi sokungasebenzi.
Ezinye izinhlelo zokusebenza eziphawulekayo zama-fuse ochungechunge lwe-NH zifaka phakathi ama-switchboard, ukuvikelwa kwe-transformer, ukufakwa kwemishini yezimboni kanye ne-switchgear. Ukuguquguquka kanye nekhono lokusingatha ama-current aphezulu ama-fuse ochungechunge lwe-NH kufanelekile ezimweni ezahlukahlukene zesistimu kagesi.
Isigaba 4: Ukukhetha OkufaneleAma-Fuse e-NH Series
NgesikhathiAma-fuse ochungechunge lwe-NHihlinzeka ngokusebenza okuhle kakhulu, ukukhetha isilinganiso sefusi esifanele sohlelo oluthile kubalulekile. Onjiniyela kumele bacabangele izici ezifana nogesi olindelekile, i-voltage elinganisiwe, kanye nezimo zemvelo lapho bekhetha ifusi efanele. Ukubonisana nonjiniyela kagesi onolwazi noma ukubhekisela ezimisweni kanye neziqondiso zomenzi kungasiza ekunqumeni isilinganiso sefusi esinembile esidingekayo ukuze kusebenze kahle futhi kuvikelwe.
Ngokufigqiwe
Ama-fuse ochungechunge lwe-NHinikeza ikhambi elihle kakhulu lokuvikela isekethe ngempumelelo nangokuthembekile kumasekethe adlulayo kanye nama-short. Ngenxa yomthamo wawo wokuphuka okuphezulu, usayizi omncane kanye nokuqina, abe yisinqumo sokuqala sonjiniyela abaningi bakagesi emhlabeni jikelele. Kungakhathaliseki ukuthi isikhungo sokulawula izimoto, uhlelo lwe-UPS, noma izinhlelo zokusebenza ezahlukahlukene zezimboni, ama-fuse ochungechunge lwe-NH ayaqhubeka nokukhombisa ukubaluleka kwawo ekuvikeleni izinhlelo zikagesi. Ngokuqonda izinzuzo kanye nokusetshenziswa kweAma-fuse ochungechunge lwe-NH, onjiniyela bangenza izinqumo ezinolwazi futhi baqinisekise ukusebenza kukagesi okuphephile.
