Imifanekiso ye-Thermal yindlela elula yokuchonga ukungafani kobushushu obucacileyo kwiisekethe zombane zesigaba sesithathu, xa kuthelekiswa neemeko zabo eziqhelekileyo zokusebenza.Ngokuhlola ukungafani kwe-thermal yazo zontathu izigaba ngecala, amagcisa angabona ngokukhawuleza ukungahambi kakuhle komsebenzi kwimilenze yomntu ngenxa yokungalingani okanye ukulayisha ngaphezulu.
Ukungalungelelani kombane ngokuqhelekileyo kubangelwa yimithwalo yesigaba esahlukileyo kodwa kusenokuba kungenxa yemiba yezixhobo ezifana noqhagamshelo oluphezulu loxhathiso.Ukungalungelelani okuncinci kombane onikezelweyo kwinjini kuya kubangela ukungalungelelani okukhulu ngoku okuya kuvelisa ubushushu obongezelelweyo kunye nokunciphisa itorque kunye nokusebenza kakuhle.Ukungalingani okukhulu kunokuvuthela i-fuse okanye i-breaker ebangela isigaba esisodwa kunye neengxaki ezinxulumene nazo ezifana nokufudumeza kwemoto kunye nomonakalo.
Ngokwenyani, akunakwenzeka ukulinganisa ngokugqibeleleyo i-voltages kwizigaba ezithathu.Ukunceda abaqhubi bezixhobo babone amanqanaba awamkelekileyo okungalungelelani, iNational Electrical
Umbutho wabavelisi (i-NEMA) uyile iinkcukacha zezixhobo ezahlukeneyo.Ezi ziseko ziyingongoma eluncedo yokuthelekisa ngexesha lokugcinwa kunye nokusombulula ingxaki.
Kufuneka kujongwe ntoni?
Thatha imifanekiso ye-thermal yazo zonke iipaneli zombane kunye nezinye iindawo zoxhumo oluphezulu ezifana nokuqhuba, ukuqhawula, ukulawula njalo njalo.Apho ufumana khona amaqondo obushushu aphezulu, landela loo sekethi kwaye ujonge amasebe ahambelanayo kunye nemithwalo.
Khangela iiphaneli kunye nolunye uqhagamshelo olucinyiweyo.Ngokufanelekileyo, kufuneka ujonge izixhobo zombane xa zifudumele ngokupheleleyo kwaye kwiimeko ezizinzileyo kunye neepesenti ezingama-40 zomthwalo oqhelekileyo.Ngaloo ndlela, imilinganiselo inokuhlolwa ngokufanelekileyo kwaye ithelekiswe neemeko eziqhelekileyo zokusebenza.
Yintoni omawuyijonge?
Umthwalo olinganayo kufuneka ulingane namaqondo obushushu alinganayo.Kwimeko yomthwalo ongalungelelananga, isigaba(s) esithwele kakhulu siya kubonakala sishushu kunezinye, ngenxa yobushushu obuveliswa kukuxhathisa.Nangona kunjalo, umthwalo ongalinganiyo, ukugqithisa, uxhulumaniso olubi, kunye nomcimbi we-harmonic unokudala ipateni efanayo.Ukulinganisa umthwalo wombane kuyadingeka ukuxilonga ingxaki.
Isekethi epholileyo kunesiqhelo okanye umlenze unokubonisa inxalenye engasebenziyo.
Yinkqubo ephilileyo yokudala indlela yokuhlola rhoqo equka zonke izidibaniso eziphambili zombane.Usebenzisa isoftware eza nomfanekiso oshushu, gcina umfanekiso ngamnye owuthathayo kwikhompyuter kwaye ulandele imilinganiselo yakho ngokuhamba kwexesha.Ngaloo ndlela, uya kuba nemifanekiso esisiseko yokuthelekisa nemifanekiso yamva.Le nkqubo iya kukunceda ukuba ubone ukuba indawo eshushu okanye epholileyo ayiqhelekanga.Ukulandela isenzo sokulungisa, imifanekiso emitsha iya kukunceda ubone ukuba ukulungiswa kube yimpumelelo.
Yintoni emele "isilumkiso esibomvu?"
Ukulungiswa kufuneka kubekwe phambili ngokhuseleko kuqala-oko kukuthi, iimeko zezixhobo ezibeka umngcipheko wokhuseleko-zilandelwa kukubaluleka kwesixhobo kunye nobukhulu bokunyuka kobushushu.I-NETA (InterNational Electrical
Izikhokelo zoMbutho woVavanyo) zicebisa ukuba amaqondo obushushu amancinci njenge-1 ° C ngaphezulu kwe-ambient kunye ne-1 ° C ephezulu kunesixhobo esifanayo esinomthwalo ofanayo angabonisa ukusilela okunokwenzeka okufuna uphando.
Imigangatho ye-NEMA (NEMA MG1-12.45) ilumkisa ngokuchasene nokusebenzisa nayiphi na injini kumbane ongalungelelaniyo ongaphezu kwepesenti enye.Ngapha koko, i-NEMA icebisa ukuba iinjini zincitshiswe ukuba zisebenza ngokungalingani okuphezulu.Iipesenti ezingalungelelananga ezikhuselekileyo ziyahluka kwezinye izixhobo.
Ukungaphumeleli kweMoto sisiphumo esiqhelekileyo sokungalingani kombane.Iindleko ezipheleleyo zidibanisa iindleko zemoto, umsebenzi ofunekayo ukutshintsha imoto, ixabiso lemveliso elahliweyo ngenxa yemveliso engalinganiyo, ukusebenza komgca kunye nengeniso elahlekileyo ngexesha umgca uphantsi.
Izenzo zokulandelela
Xa umfanekiso we-thermal ubonisa ukuba i-conductor yonke ishushu kunezinye iinxalenye kwinxalenye yesekethe, umqhubi unokuncitshiswa okanye alayishwe kakhulu.Jonga umlinganiso womqhubi kunye nomthwalo wangempela ukuze ubone ukuba yiyiphi imeko.Sebenzisa i-multimeter ene-clamp accessory, i-clamp meter okanye i-analyzer yekhwalithi yamandla ukujonga ibhalansi yangoku kunye nokulayisha kwisigaba ngasinye.
Kwicala le-voltage, khangela ukhuseleko kunye ne-switchgear yokuhla kwamandla ombane.Ngokubanzi, amandla ombane ombane kufuneka abe ngaphakathi kwe-10 % yomlinganiselo we-nameplate.Ukungathathi hlangothi kumbane ophantsi komhlaba kunokuba luphawu lwendlela elayishwe ngayo isistim yakho okanye inokuba luphawu lweharmonic yangoku.Amandla ombane aphakathi phakathi ukuya emhlabeni angaphezulu kwe-3 % yamandla ombane aqhelekileyo kufuneka aqalise uphando olongezelelweyo.Kwakhona cinga ukuba imithwalo iyatshintsha, kwaye isigaba sinokuthi ngequbuliso sibe sezantsi kakhulu ukuba umthwalo wenqanaba elinye uza kwi-intanethi.
I-voltage yehla ngapha kwe-fuses kunye nokutshintsha kwakhona kunokubonakala njengokungalinganiyo kwi-motor kunye nobushushu obugqithisileyo kwindawo yenkathazo.Phambi kokuba ucinge ukuba unobangela ufunyenwe, jonga kabini umfanekiso we-thermal kunye neemitha ezininzi okanye imilinganiselo yangoku ye-clamp meter.Ayizizo i-feeder okanye iisekethe zesebe ekufuneka zilayishwe ukuya kumda ovumelekileyo.
Ukulinganisa komthwalo wesekethe kufuneka kwakhona kuvumele i-harmonics.Esona sisombululo sixhaphakileyo sokulayisha ngaphezulu kukusasaza kwakhona imithwalo phakathi kweesekethe, okanye ukulawula xa imithwalo ifika ngexesha lenkqubo.
Ukusebenzisa i-software ehambelanayo, ingxaki nganye ekrokrelwayo etyhilwe kunye nomfanekiso we-thermal ingabhalwa kwingxelo ebandakanya umfanekiso we-thermal kunye nomfanekiso wedijithali wesixhobo.Leyo yeyona ndlela ilungileyo yokunxibelelana ngeengxaki kunye nokucebisa ukulungisa.
