11. Ndingenza ntoni ukuba imitha ayinayo umboniso?
Impendulo: Qinisekisa ukuba igalelo lombane lombane liqhelekileyo, khangela ukuba kukho uxhulumaniso lwenyani kumgca ongenayo wonikezelo lwamandla lwesixhobo, kwaye usebenzise i-multimeter ukulinganisa ukuba i-voltage ye-terminal yomgca ongenayo wesixhobo. iqhelekile kwaye iyahlangabezana neemfuno zokuodola.nokuba iimfuno ziyafezekiswa.Qinisekisa ukuba unikezelo lwamandla oluncedisayo olufanelekileyo (AC/DC85-265V) longezwe kwitheminali yobonelelo lwamandla encedisayo yesixhobo.Umbane wombane oncedisayo odlula uluhlu oluchaziweyo ungonakalisa isixhobo kwaye awukwazi ukufunyanwa.Ungasebenzisa i-multimeter ukulinganisa ixabiso le-voltage yobonelelo lwamandla ancedisayo.Ukuba amandla ombane ombane aqhelekile kwaye imitha ayinaso isibonisi, unokucinga ngokucima kwaye uvule kwakhona amandla.
12. Sisiphi isizathu sokuba isixhobo singaphumeleli ukubonisa umsebenzi ofunekayo?
Impendulo: Khangela ukuba imitha yalo mzekelo inalo msebenzi.Imitha oyi-odolileyo kufuneka iqonde imisebenzi equlethwe kuyo.Iimodeli ezahlukeneyo zinemisebenzi eyahlukeneyo, ngoko ke akufuneki uqhagamshele ngokungaboniyo okanye uzisebenzise ngobumfama.
13. Kutheni ixabiso elibonisiweyo langoku kunye nombane likhulu kakhulu okanye lincinci kakhulu (ubudlelwane obuninzi kunye nexabiso lokwenene)?
A: Umlinganiselo we-transformer ye-CT kunye ne-PT yemitha ngokwayo ayibekwanga.Unokujonga incwadi yomsebenzisi eqhotyoshelwe kumitha okanye uqhagamshelane nenkxaso yobugcisa ngokuthe ngqo ngoncedo.
14. Kukho iimpazamo ezicacileyo kumaxabiso abonisiweyo ombane kunye nowangoku (umzekelo, i-voltage yesigaba B inkulu kakhulu) ngoba?
Impendulo: Isenokuba yingxaki ngolungiselelo lwendlela yocingo.Guqula indlela yocingo ye-voltage okanye yangoku ngokubhekiselele kwi-wiring yangempela yenkqubo kwiisethingi zesixhobo.
15. Yintoni endimele ndiyenze ukuba amaxabiso alinganisiweyo ka-U, I, P, njl.
Impendulo: Isenokuba yingxaki yeentambo okanye ingxaki yokuseta.Okokuqala, kufuneka uqinisekise ukuba i-voltage echanekileyo kunye neempawu zangoku zixhunyiwe kwimitha.Ungasebenzisa i-multimeter ukulinganisa umqondiso we-voltage, kwaye usebenzise imitha yokulinganisa ukulinganisa umqondiso wangoku ukuba kuyimfuneko.Okwesibini, qiniseka ukuba uxhulumaniso lomgca wesignali luchanekile, njengegama elifanayo lokuphela kwesignali yangoku (oko kukuthi, ukuphela komgca ongenayo), nokuba ngaba ukulandelelana kwesigaba sesigaba ngasinye kuphosakele.Imitha yamandla emisebenzi emininzi inokubona umboniso wamandla ojongano, kuphela kwimeko yokuhanjiswa kwamandla okubuyela umva, idatha yamandla esebenzayo ayilunganga, kwaye idatha yamandla esebenzayo ayilunganga kusetyenziso ngokubanzi.Ukuba uphawu lwamandla asebenzayo lubi, kunokwenzeka ukuba igalelo langoku kunye nemigca yokuphuma ixhunyiwe ngokungalunganga.Kunjalo, uqhagamshelo lolandelelwano lwesigaba esingalunganga luya kubangela umboniso wamandla ongaqhelekanga.Ukongezelela, kufuneka kuqatshelwe ukuba amandla abonakaliswe imitha lixabiso legridi yokuqala.Ukuba i-multiplier ye-voltage kunye ne-transformer yangoku ebekwe kwimitha ayihambelani ne-multiplier ye-transformer yangempela esetyenzisiweyo, ukubonakaliswa kwamandla ombane kuya kuba kungachanekanga.I-voltage kunye nemigangatho yangoku kwimitha ayivumelekanga ukuba iguqulwe emva kokushiya i-factory.Inethiwekhi yocingo ingatshintshwa ngokwendlela yoqhagamshelo lwenyani kwisiza, kodwa ukusetwa kwendlela yocingo kwimenyu yenkqubo kufuneka ihambelane nendlela yokwenyani yocingo, kungenjalo iya kukhokelela kulwazi olungalunganga lokubonisa.
16. Ndimele ndenze ntoni ukuba amandla ombane akachanekanga?
Impendulo: Isenokuba yingxaki yeentambo.Ukuqokelelwa kwamandla ombane kwimitha kusekelwe kumlinganiselo wamandla.Okokuqala jonga ukuba ixabiso lamandla emitha liyahambelana nomthwalo wangempela.Imitha yamandla enemisebenzi emininzi ixhasa umlinganiselo wamandla weendlela ezimbini.Kwimeko ye-wiring engalunganga, xa amandla asebenzayo ewonke engalunganga, amandla aya kuqokelelwa kwi-reverse yamandla asebenzayo, kwaye amandla asebenzayo asebenzayo akayi kuqokelelwa.Eyona ngxaki ixhaphakileyo esetyenziswayo kwintsimi kukudityaniswa kwangasemva kweengcingo ezingenayo neziphumayo ze-transformer yangoku.Imitha yamandla emisebenzi emininzi inokubona amandla asebenzayo asayiniweyo wesigaba sokwahlula.Ukuba amandla akanawo, inokuba lucingo olungalunganga.Ukongeza, udibaniso olungalunganga lolandelelwano lwesigaba luya kubangela ukungaqhelekanga kwamandla ombane wemitha.
