Izicelo eziningi ze-elekthronikhi zisebenzisa ama-resistance anti-power, ngokuvamile i-watt 1 / 8th noma ngaphansi. Kodwa-ke, izinhlelo ezifana nokunikezwa kwamandla, amabhuleki ashukumisayo, ukuguqulwa kwamandla, ama-amplifiers, nama-heaters ngokuvamile badinga ukumelana namandla aphezulu. Amagciwane amakhulu aphezulu amelana nama-resistors anikezwe u-1 watt noma imithwalo emikhulu futhi ayatholakala ku-kilowatt ububanzi.
Amandla Okusekela Amandla
Isilinganiso samandla somphikisi sichaza ukuthi amandla angakanani omelana nawo angaphatha ngokuphepha ngaphambi kokuba impi iqale ukulimala unomphela. Amandla ahlakazwa ukumelana angatholakala kalula usebenzisa umthetho wokuqala kaJoule, amandla = I-Voltage x Yamanje ^ 2. Amandla ahlakazwa ukumelana aguqulwa ekushiseni futhi akhulise izinga lokushisa lomelana. Ukushisa kokumelana nakho kuzoqhubeka ukukhuphuka kuze kufinyelele endaweni lapho ukushisa kuhlakazeka khona emoyeni, ebhodini lesifunda, nasezindaweni ezizungezile kulinganisa ukushisa okwenziwe. Ukugcina izinga lokushisa lomncintiswano oluphansi lizogwema umonakalo kumelana futhi livumele ukusingatha izimpondo ezinkulu ngaphandle kokonakaliswa noma ukulimala. Ukusebenzisa ukumelana kwamandla ngaphezu kwamandla ayo okulinganisa nokushisa kungaholela emiphumeleni enzima kuhlanganise nokushintsha kwezinga lokumelana, ukunciphisa isikhathi sokusebenza, ukuvula okuvulekile, noma izinga lokushisa eliphakeme kangangokuthi ukumelana kungabamba umlilo noma kubambe izinto ezizungezile ngomlilo. Ukuze ugweme lezi zindlela zokuhluleka, izimpikiswano zamandla ngokuvamile zihleka ngokusekelwe ezimweni zokusebenza ezilindelekile .
Amanqamuzana emandla avame ukukhudlwana kunabalingani bawo abaphansi. Usayizi okhulayo usiza ukukhipha ukushisa futhi kuvame ukusetshenziselwa ukuhlinzeka ngezinketho zokuphakama ze-heatsinks. Ama-resistance resistors aphezulu nawo avame ukutholakala emaphakheji avuthayo amalangabi ukuze kuncishiswe ingozi yokukhubazeka okunobungozi.
Ukuphikiswa kwamandla okudlulayo
Ukulinganisa kwamanzi okumelana namandla kukhonjiswe ekushiseni kwama-25C. Njengoba izinga lokushisa lokumelana kwamandla likhuphuka ngaphezu kwe-25C, amandla amelana nokuphepha aqala ukwehla. Ukuze ulungiselele izimo zokusebenza ezilindelekile, izakhi zinikeza ishadi lokuhlekisa elibonisa ukuthi amandla amelana kanjani nomswakama njengoba izinga lokushisa lokumelana likhuphuka. Kusukela ku-25C kujwayelekile ukushisa kwamakamelo, futhi noma yikuphi amandla anqatshelwe ukumelana kwamandla kudala ukushisa, ukugijima kokumelana kwamandla ngesikhathi esilinganisiwe samandla ngokuvamile kunzima kakhulu. Ukuphendula ngomthelela wokushisa okusebenzayo kwabakhiqizi bemikhakha kuhlinzeka ngendonga yokudula amandla ukusiza abaqambi ukulungisa ukulinganiselwa kwezwe langempela. Kungcono ukusebenzisa i-curate amandla okugwedla njengesiqondiso futhi uhlale kahle endaweni ephakanyisiwe yokusebenza. Uhlobo ngalunye lokumelana luyoba ne-curating ehlukile yokuhlukumezeka nokuhlukahluka okuphezulu kokusebenza kwezidingo.
Izinto eziningana zangaphandle zingathinta amandla okuphikisa amandla omphikisi. Ukwengeza ukupholisa umoya okuphoqelelwe, ukushisa kwe-heatsink, noma ingxenye engcono yokukhuphuka ukusiza ukuchitha ukushisa okwenziwe umelana kuzovumela ukuphikisana nokuphatha amandla amaningi futhi kugcine izinga lokushisa eliphansi. Kodwa-ke, ezinye izici zisebenza ngokumelene nokupholisa, njengokungenisa ukushisa okuvaliwe endaweni eseduze, izingxenye ezithinta ukushisa eziseduze nezimo eziphilayo ezifana nomswakama nokuphakama.
Izinhlobo zamanqamu aphezulu wamandla
Izinhlobo eziningana zamagciwane amakhulu aphezulu emakethe. Uhlobo ngalunye lokumelana luhlinzeka ngamakhono ahlukene wezinhlelo zokusebenza ezahlukene. Ama-resistant wirewound avamile futhi atholakale ngezici ezihlukahlukene zefomu, kusukela ekukhuphukeni komhlaba, emisebeni, e-axial, nase-chassis mount design yokushisa okushisayo okukhulu. Izimpikiswano ezingenayo inductive wirewound nazo zitholakalayo ekusetshenzisweni kwamandla aphezulu okuxoshwa. Ukusetshenziswa kwamandla aphezulu kakhulu, njengokushusha okunamandla, ama-resistor wire, okusetshenziselwa ukushisa, kukhona okukhethwa kukho, ikakhulukazi uma umthwalo kulindeleke ukuthi ube ngamakhulu ezinkulungwane zamatts.
