Imibuzo ebuzwa qho

Ngaba i-amp draw ingalimaza umthombo wamandla?

Ukuzama ukuzoba ii-amps ezingaphezulu kunokuhanjiswa ngumthombo kungonakalisa umthombo, isixhobo, okanye zombini. Imithombo yamandla inomlinganiselo ophezulu wangoku. Ukodlula ezi zinto kubangela ukuwa kwamandla ombane, ukufudumeza okugqithisileyo, kunye nokusilela okunokwenzeka. Izixhobo zokukhusela iisekethe ezifana ne-fuses kunye ne-breakers zikhusela umonakalo ngokuphazamisa okwangoku xa imida ekhuselekileyo igqithisiwe.

Kutheni i-amp draw ihluka ngexesha lokusebenza?

Uninzi lwezixhobo azilugcini umzobo wangoku. IiMotor zoba ngaphezulu ngexesha lokuqalisa kunye naphantsi komthwalo onzima. Izifudumezi zijikeleza kwaye zicima. Ukuguquguquka kwevoltage kumthombo wamandla nako kuchaphazela ukutsalwa kwe-amp - njengoko umbane wehla, ukonyuka kwangoku ukugcina imveliso yamandla efanayo. Ubushushu butshintsha ukuchasana kwii-conductors kunye namacandelo, ukuhluka ngokuqhubekayo kokuhamba kwangoku.

Ingaba into yamandla iluchaphazela njani ubalo lwe-amp draw?

I-Power factor ibonakala kwiinkqubo ze-AC kunye nemithwalo ye-inductive okanye i-capacitive. Imele umahluko wesigaba phakathi kombane kunye nokhoyo. Umba wamandla ongaphantsi kwe-1.0 uthetha ukuba isixhobo sizoba ngoku ngakumbi kunezibalo ezilula ze-watt/volt zicebisa. Ukufumana i-amp yokwenyani ukuzoba kwiinkqubo ze-AC kunye ne-factor yamandla engalunganga: I-Amps=i-Watts ÷ (IiVolts × iFactor yaMandla). IiMotor ngokuqhelekileyo zinezinto zamandla ezijikeleze i-0.7-0.85.

Ngaba ii-amps ziyatyhalwa okanye zitsalwe kwisekethe?

Okwangoku "itsalwa" okanye "itsalwa" ngumthwalo, ayityhalwa ngumthombo. Umthombo unikeza i-voltage (uxinzelelo lombane), kwaye ukuchasana komthwalo kumisela ukuba kungakanani ukuhamba ngoku. Yiyo loo nto igama elithi "amp draw" kunokuba "i-amp push." Umthombo kufuneka ube nako ukubonelela ngoku ofunekayo, kodwa umthwalo ulawula ukuba kuhamba kangakanani.

Ibhetri{0}usetyenziso olunamandla ngakumbi luzuza ekuqondeni ukutsalwa kwe-amp, kuba usetyenziso lwangoku lumisela ngokuthe ngqo ixesha lokuqhuba phakathi kwentlawulo. Nokuba ukulinganisa ibhanki yebhetri yendlu, ukukhetha izixhobo zombane, okanye ukuyila inkqubo yesithuthi sombane, izibalo ezichanekileyo zangoku zenza isiseko soyilo oluthembekileyo lombane.

Ifomula ngokwayo - i-amps ilingana neewathi ezahlulwe ngeevolthi - zihlala zilula. Ukuntsokotha kuvela ekuqondeni indlela yokwenyani{3}}imeko zehlabathi eziguqula ngayo amaxabiso acingelwayo. I-voltage sag, into yamandla, ukuqala kokutyalwa, kunye nelahleko esebenzayo konke kuchaphazela ukuhamba kwangoku. Ukubalwa kwengxelo kwezi ziguquko ngexesha lesigaba soyilo kuthintela iingxaki ngexesha lokusebenza.

Iinkqubo zanamhlanje zolawulo lwebhetri kwiibhetri ze-lithium ion ziphatha ubuninzi bobu bunzima ngokuzenzekelayo, ukujonga umzobo wangoku kunye nokukhusela iiseli emonakalweni. Kodwa nangobuchwephesha be-elektroniki, ukwazi umzobo we-amp yenkqubo yakho kunceda ukufumanisa iingxaki, ukucwangcisa ukwandiswa, kunye nokwandisa ukusebenza.
