Isihloko: Qonda izinzuzo kanye nokusetshenziswa kweAmafuse ochungechunge lwe-NH
ethula
Emkhakheni wobunjiniyela bakagesi, ukukhetha izingxenye ezifanele zohlelo oluthile kubalulekile ukuze kuqinisekiswe ukuphepha nokuthembeka kwezinhlelo zikagesi.Uma kukhulunywa ngokuvikelwa kwe-fuse, amafuse ochungechunge lwe-NH agqama njengenye yezinketho eziguquguqukayo nezithembekile emakethe.Kule bhulogi, sizocubungula imininingwane yeAmafuse ochungechunge lwe-NH, xoxani ngezinzuzo nezicelo zabo, futhi nifunde ukuthi kungani benconywa kakhulu onjiniyela emhlabeni jikelele.
Isigaba 1: ZiyiniAmafuse ochungechunge lwe-NH?
Amafuse ochungechunge lwe-NHukusebenza okuphezulu, amafuse kagesi aphansi aklanyelwe ukuhlinzeka ngokuvikelwa kwesekethe okuthembekile ngokumelene namasekhethi adlulele kanye namafushane.I-“NH” imele i-“Niedersspannungs-Hochleistungssicherung”, okuyigama lesiJalimane elihunyushwa ngokuthi “i-fuse yokusebenza okuphezulu kwamandla kagesi aphansi”.Lawa ma-fuse ajwayele ukusetshenziswa ezinhlelweni zokusabalalisa amandla ezigaba ezintathu, ikakhulukazi ezinhlelweni lapho ukuvikelwa kwezimoto kubaluleke kakhulu.
Isigaba sesibili: izinzuzo zeAmafuse ochungechunge lwe-NH
Amafuse ochungechunge lwe-NHnikeza izinzuzo ezimbalwa phezu kwamafuse afanayo.Okokuqala, lawa ma-fuse anamandla amahle kakhulu okuphuka, okusho ukuthi angaphazamisa ngokuthembekile imisinga yamaphutha aphezulu.Lesi sici siqinisekisa ukuthi i-fuse ivula ngokushesha isekethe, ivimbele ukulimala kwemishini kanye nezingozi ezingaba khona zikagesi.Ngaphezu kwalokho, amafuse ochungechunge lwe-NH aziwa ngokumelana kwawo nesekethe emfishane ephezulu kanye nokumelana nokushisa, okusiza ukwandisa impilo yawo yesevisi nokuthuthukisa ukuqina.
Ukwengeza, usayizi ohlangene weAmafuse ochungechunge lwe-NHigcina isikhala esibalulekile emakhabetheni kagesi.Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho isikhala silinganiselwe.Ukwengeza, ukulingana okunembile kwalawa ma fuse kuqinisekisa ukusebenza okuthembekile futhi kunciphisa ubungozi bokukhubeka ngengozi, ngaleyo ndlela kwandise ukusebenza kahle nokuphepha kohlelo lukagesi.
Into yesithathu: ukusetshenziswa kweAmafuse ochungechunge lwe-NH
Amafuse ochungechunge lwe-NHzisetshenziswa kabanzi ezimbonini ezahlukahlukene kanye nezicelo ngenxa yezici zazo zokusebenza ezinhle kakhulu.Avame ukusetshenziswa ezikhungweni zokulawula izimoto (MCCs) ukuvikela izinjini kanye namasekethe azo okulawula.Lawa ma-fuse adlala indima ebalulekile ekuvikeleni ama-motor ezimeni ezidlulele ezibangelwa amaphutha noma ukwehluleka kwemishini.
Amafuse ochungechunge lwe-NH nawo asetshenziswa ezinhlelweni zikagesi ezingaphazamiseki (i-UPS) ukuze zinikeze ukuvikeleka okuthembekile kwemithwalo ebalulekile njengezikhungo zedatha, izibhedlela nezinye izinhlelo zokusebenza ezibucayi.Izilinganiso zamanje ezinamaphutha aphezulu kanye nesikhathi sokuphendula esisheshayo salawa ma fuse siwenza alungele ukuqinisekisa amandla angaphazanyiswa kanye nokunciphisa isikhathi sokuphumula.
Ezinye izinhlelo zokusebenza eziphawulekayo zamafuse ochungechunge lwe-NH zihlanganisa ama-switchboards, ukuvikelwa kwe-transformer, imishini yezimboni kanye nokufakwa kwe-switchgear.Ukuguquguquka kanye nekhono lokuphatha amafusi ochungechunge lwe-NH afanele izinhlobonhlobo zezimo zesistimu kagesi.
Isigaba 4: Ukukhetha OkulungileNH Series Fuse
NgenkathiAmafuse ochungechunge lwe-NHhlinzeka ngokusebenza okuhle kakhulu, ukukhetha isilinganiso esifanele se-fuse sohlelo oluthile kubalulekile.Onjiniyela kufanele bacabangele izici ezifana namanje okulindelekile, i-voltage elinganiselwe, nezimo zemvelo lapho bekhetha i-fuse efanele.Ukubonisana nonjiniyela kagesi onolwazi olunzulu noma ukubhekisela ekucacisweni komkhiqizi nemihlahlandlela kungasiza ekunqumeni isilinganiso esinembile se-fuse esidingekayo ukuze usebenze kahle nokuvikela.
Ngokufigqiwe
Amafuse ochungechunge lwe-NHhlinzeka ngesixazululo esihle kakhulu sokuvikela isifunda esisebenza kahle nesithembekile ngokumelene namasekethe ama-overcurrent namafushane.Ngomthamo wabo omkhulu wokuphuka, usayizi ohlangene kanye nokuqina, sebephenduke ukhetho lokuqala lonjiniyela abaningi bakagesi emhlabeni jikelele.Kungakhathaliseki ukuthi isikhungo sokulawula izimoto, uhlelo lwe-UPS, noma izinhlobonhlobo zezinhlelo zokusebenza zezimboni, ama-fuse ochungechunge lwe-NH ayaqhubeka nokubonisa ukubaluleka kwawo ekuvikeleni amasistimu kagesi.Ngokuqonda izinzuzo kanye nokusetshenziswa kweAmafuse ochungechunge lwe-NH, onjiniyela bangenza izinqumo ezinolwazi futhi baqinisekise ukusebenza kukagesi okuphephile.
