Yintoni intlawulo-Isixhobo sokuVavanya sokukhupha?

Hlaziya{0}}khupha izixhobo zovavanyo lokusebenza

Ukuhlawuliswa kwebhetri{0}}ukukhupha uvavanyo lokuqhuba lolona vavanyo lusisiseko, olubandakanya intlawulo{1}}yeyunithi yokukhupha kunye neyunithi yenkqubo yolawulo. Ingakwazi ukulawula ukude ibhetri yamandla ngekhompyutha ukwenza rhoqo-ivoltage, engaguqukiyo-yangoku, okanye ukusetwa kwangaphambili intlawulo yejiko lamandla{5}}ukukhupha. Ngokusebenzisa i-voltage, yangoku, kunye nezinzwa zobushushu, iiparamitha ezihambelanayo zinokulinganiswa, kunye neeparamitha zovavanyo ezifana nomthamo webhetri yamandla, amandla, kunye nokungaguquguquki kwebhetri.

Izixhobo zokuvavanya zihlelwa ngokubanzi ngokwamanqanaba ombane kunye namandla ombane ukuhlangabezana neemfuno zovavanyo lokusebenza kweebhetri zamandla kunye neepakethi zebhetri ezinemilinganiselo yombane eyahlukeneyo kunye namandla. Umzekelo, isixhobo sovavanyo lwebhetri yeseli enye ngokuqhelekileyo sikhetha uluhlu lwamandla ombane osebenzayo we-0–5 V kunye noluhlu lwangoku olusebenzayo luka-0–100 A, olunokufikelela kwiimfuno ezisisiseko zovavanyo lokwenziwa komsebenzi kwiintlobo ezininzi zeebhetri zamandla ezithuthi. Kuvavanyo olusisiseko lokusebenza kweepakethi zebhetri{7}eziphezulu zamandla, uluhlu lwamandla ombane kufuneka lukhethwe ngokoluhlu lwebetri yoluhlu lombane; izixhobo zovavanyo eziqhelekileyo ezisetyenziswa jikelele zifuna i-0–500 V enegunya elingaphezulu komda we-150–200 kW.

Umzobo 6-7 ubonisa inkqubo yovavanyo lwebhetri yeArbin emininzi{2} ephuhliswe yinkampani ethile, enokuseta iindlela ezahlukeneyo zokuhlawulisa{3}}inkqubo yokukhupha isoftware kunye nerekhodi ngexesha lokwenyani amandla ombane, angoku, ukukhupha intlawulo, amandla, kunye neeparamitha zobushushu bomphezulu webhetri phantsi kovavanyo.

Izixhobo zokuvavanya ukuchasana kwangaphakathi

Ukuxhathisa kwangaphakathi kwebhetri, njengomlinganiselo ophambili weparameter, inokuvavanywa ngeendlela eziquka isikwere-indlela yangoku yamaza, indlela yebhulorho ye-AC, indlela yokumelana ne-AC, indlela ye-DC volt{1}}indlela ye-ampere, indlela emfutshane{2}}yendlela yesekethe yangoku, kunye nendlela ye-pulse yangoku. Indlela yokukhupha i-DC ilula kwaye isetyenziswa ngokuqhelekileyo kubunjineli. Le ndlela isebenzisa umsinga omkhulu ngephanyazo (ngokuqhelekileyo amashumi aliqela ukuya ngaphezu kwekhulu le-ampere) okhutshelwa ebhetrini, ulinganisa ukuhla kwamandla ombane ngoko nangoko kwibhetri, kwaye ubala ukuxhathisa kwangaphakathi usebenzisa umthetho ka-Ohm. Indlela ye-AC igalela umqondiso wangoku we-AC ephantsi-ixesha eliphantsi kwibhetri kwaye ilinganisa umahluko wesigaba phakathi kombane ophantsi{7}}womthamo ophindaphindiweyo kunye nophantsi{8}}obuxhakaxhaka bangoku kwiitheminali zebhetri ukubala ukuxhathisa kwangaphakathi. Uninzi lwezixhobo zovavanyo lwangaphakathi eziveliswa ngabavelisi zisebenzisa indlela ye-AC yovavanyo lwebhetri. Amanani 6-8 kunye ne-6-13 abonisa abavavanyi abaqhelekileyo bangaphakathi kunye neeparitha zabo.

Isixhobo sokulinganisa ubushushu

Ukunyuka kobushushu bebhetri ngexesha lokutshaja{0}}inkqubo yokukhupha yenye yezinto ezibalulekileyo. Nangona kunjalo, uvavanyo oluqhelekileyo lunokulinganisa kuphela iiparamitha zendawo kwiqokobhe lebhetri. Ngokubanzi, intlawulo-isixhobo sokukhupha sixhotyiswe ngenkqubo yokufumana ubushushu ehambelanayo enomsebenzi wokuvumelanisa idatha yobushushu ngexesha lokuhlawuliswa{4}}inkqubo yokukhupha. Ukongeza, izixhobo zokuvavanya ubushushu zikwabandakanya{6}}iithemometha ezingaqhagamshelwanga kunye neekhamera zokujonga ubushushu. Ikhamera yokujonga i-thermal inokuqokelela imbali yokutshintsha kweqondo lobushushu kwindawo enye okanye ngaphezulu kwebhetri kwaye ikhuphe idatha yokutshintsha kweqondo lobushushu kwiindawo eziqhelekileyo zokulinganisa, iyenza isixhobo sokulinganisa ubuchwephesha kuhlalutyo lwendawo yobushushu bebhetri. Ithemometha engadibanisiyo kunye nekhamera yomfanekiso we-thermal iboniswe kuMfanekiso 6-9 kunye noMzobo 6-10, ngokulandelelanayo.
