Uninzi lwezicelo zeteknoloji zisebenzisa ama-resistance resistance aphantsi, ngokuqhelekileyo u-1/8 watt okanye ngaphantsi. Nangona kunjalo, izicelo ezifana nokunikezwa kwamandla, iibhuleki ezinamandla, ukuguqulwa kwamandla, ukukhulisa amandla, kunye neentsimbi zihlala zifuna abaxhasi bamandla aphezulu. Izikhundla eziphezulu zamandla okuxhathisa amandla anqatshelwe i-1 watt okanye imithwalo ephezulu kwaye iyafumaneka kwi-kilowatt.
Amanqwanqwa okuMelana neMandla
Isilinganisi samandla somxhatshazo sichaza ukuba unamandla omelana nomxhasi angaphatha njani ngaphambi kokuba umxhatshazi aqale ukuhlaselwa ngumonakalo. Amandla anqatshelwe ngumxhatho angatholakala kalula usebenzisa umthetho wokuqala weJoule, amandla = I-Voltage x Yamanje ^ 2. Amandla anqatshelwe ngumxhatshazo aguqulwa aze atshise kwaye akhulise ukushisa komxhatshazo. Ubushushu be-resistor buya kuqhubeka benyuka de bufike kwindawo apho ukushisa kuphazamiseka emoyeni, kwibhodi yesiphaluka kunye nokusingqongileyo kwendawo ejikelezayo. Ukugcina ukushisa kwe-resistor low kuya kuphelisa umonakalo kumxhatshazo kwaye uvumele ukusingatha ii-currents ezinkulu ngaphandle kokuthotywa okanye ukulimala. Ukusebenzisa umbane wamandla angaphezu kwamandla ayo alinganisiweyo kunye nobushushu kungabangela imiphumo emibi kuquka ukutshintshwa kwexabiso lokumelana nokunciphisa, ukunciphisa ixesha lokusebenza, ukujikeleza, okanye ukushisa okuphakamileyo kangangokuthi umxhasi angabamba umlilo okanye abambe izixhobo ezijikelezayo ngomlilo. Ukuphepha ezi modes zokungaphumeleli, ukuxhatshazwa kwamandla okuhlala kuncibilikiswa ngokusekelwe kwiimeko ezilindelekileyo zokusebenza .
Abaxhatshazi bamandla ngokuqhelekileyo banamakhulu kunabo abalingani babo abaphantsi. Ubungakanani obandayo bunceda ukususa ubushushu kwaye ngokuqhelekileyo kusetyenziselwa ukubonelela iindawo ezikhethiweyo ze-heatsinks. Amagatya amakhulu aphezulu ahlala efumaneka kwiiphakheji ezingalawulekiyo zomlilo ukunciphisa umngcipheko weemeko zokungaphumeleli.
Umxhasi weMandla
Ukulinganiswa kwamanzi okuxhatshazwa kwamandla kuchazwe kwindleko ye-25C. Njengoko ubushushu be-resistor power bukhuphuka ngaphezu kwe-25C, amandla anokumelana nokukhusela aqala ukuhla. Ukulungelelanisa iimeko ezilindelekileyo zokusebenza, ukuvelisa ukubonelela ngeesitidi ezityhawulayo ezibonisa ukuba unamandla omelana nomntu onokumelana nawo angakwazi ukuphatha njani njengoko ukushisa komkhuseli kukhuphuka. Ekubeni i-25C iyimfuneko yokushisa kwegumbi, kwaye nawaphi na amandla anqanyulwa ngumbane onamandla odala ukushisa, ukuxhatshazwa kwamandla kwinqanaba legunya elilinganisiweyo lisoloko kunzima kakhulu. Ukuphendula ngefuthe lokushisa okusebenzayo kwabakhi be-resistor banikeza amandla okukhahlaza amandla ukuze bancede abenzi bokuzicwangcisa ukulungelelanisa ukulinganiselwa kwehlabathi lokwenene. Kukulungele ukusebenzisa i-curving rock curve njengesikhokelo kwaye uhlale kakuhle kwindawo ephakanyisiweyo yokusebenza. Uhlobo ngalunye lokumelana nalo luya kuba nolunye ulungelelwano olukratshiweyo kunye nokunyamezela okuphezulu okusebenzayo.
Izinto ezininzi zangaphandle zingathintela amandla okukhahlela umxhatshazo. Ukongeza ukuphoqeleka komoya ophoqelekileyo, i-heatsink, okanye iqela elincinci elincinci lokunceda ukutshabalalisa ubushushu obuveliswe ngumxhasi kuya kwenza ukuba umbane onokumelana nombane angagqithanga amandla kwaye alondoloze ukushisa okuphantsi. Nangona kunjalo, ezinye izinto zisebenza ngokuzipholisa, njengendawo yokugcina ukushisa okuveliswe kwindawo ejikelezayo, kunye nezinto ezinobume bokusingqongileyo ezifana nomswakama kunye nokuphakama.
Iintlobo zeGosa eliPhezulu loMbane
Zininzi iintlobo zamashishini aphezulu okuxhathisa amandla atholakalayo kwimarike. Uhlobo ngalunye lokumelana nalo lunika izixhobo ezahlukeneyo kwizicelo ezahlukeneyo. Ukuxhatshazwa kwe-Wirewound kuqhelekileyo kwaye kufumaneka kwiimeko ezahlukeneyo zefomu, ukusuka kwintaba yomhlaba, i-radial, i-axial, kunye ne-chassis kwintlahlela yokukhangela ukushisa okutsha. Ukuxhatshazwa kwee-wirewound non-inductive nazo ziyafumaneka kwizicelo zamandla eziphakamileyo. Izicelo ezinamandla kakhulu, ezifana nokuqhaqhaqhaqhaqhafaza, ukuxhatshaza kween-nichrome, kunye nezixhobo zokufudumala, zikhethiweyo ezilungileyo, ngakumbi xa umthwalo kulindeleke ukuba ube ngamakhulu ukuya kumawaka eetts.
