Inyama yenkomo ijeki eqhubekayo ivacuum epakisha inkqubo yolawulo yombane yokhuseleko olusetyenziswa ngokuqhelekileyo

inyama yenkomo ijerky eqhubekayo ivacuum yokupakisha inkqubo yokulawula umbane yekhonkco eliqhelekileyo lokukhusela. Vacuum eqhubekayoumatshini wokupakisha kunye nenyama yenkomo eyomileyo eyomileyo yokupakisha umatshini wokupakisha ifilimu, kwinkqubo yomsebenzi, umatshini wokupakisha ifilimu yenkomo yenkomo yenkomo ukuze kugcinwe inkqubo yolawulo lombane yemoto kunye nazo zonke iintlobo zombane kunye nolawulo lwesekethe zinokusebenza okuqhelekileyo, ukunciphisa ukubakho kobungozi obunokwenzeka. izinto, kwaye xa ukusilela kombane, ukusilela kwancitshiswa kuluhlu oluncinane kangangoko kunokwenzeka, ukuze kuqinisekiswe ukhuseleko lobuqu kunye nezixhobo, ngoko ke kufuneka ukhuseleko inkqubo yolawulo lombane, wamisa ikhonkco oluyimfuneko. Ikhonkco lokhuseleko lwenyama yenkomo elisetyenziswa ngokuqhelekileyo linokhuseleko lwangoku, ukhuseleko lomthwalo omninzi, ukhuseleko lwesekethe emfutshane, ukhuseleko lombane ongaphezulu, ukukhuselwa kwamandla ombane, ukukhuselwa kwesigaba esivulekileyo, ukukhuselwa okubuthathaka kwemagnethi kunye nokhuseleko olukhawulezayo, njl. Emva koko jongani kunye.



inyama yenkomo ijerky eqhubekayo ivacuum yokupakisha inkqubo yokulawula umbane yekhonkco eliqhelekileyo lokukhusela. Inyama yenkomo yenkomo eqhumayo eqhubekayo yokupakisha umatshini wokucoca umatshini amacandelo ombane kumsebenzi oqhelekileyo, ngokusebenzisa umsinga ngaphakathi komgangatho olinganisiweyo. Ngexesha elifutshane, okoko nje ukunyuka kwamaqondo obushushu kuvunyelwe, nako kunokuba ngaphezulu kwereyithingi yangoku, oku zonke iintlobo zezixhobo zombane okanye amacandelo ngokwemeko yawo yokugquma yahlukile, kodwa amandla omthwalo. Ukhuseleko lwangoku kukukhusela umgaqo osisiseko wovavanyo lombane wesignali emva kokuguqulwa okanye ukusondeza ukulawula into ekhuselweyo, xa ixabiso lokumisela ukufikelela, izixhobo zokukhusela. Uhlobo lwangoku lune-overcurrent, ukhuseleko lomthwalo ogqithisiweyo, isiphaluka esifutshane kunye nezigaba ezininzi.

a, ukhuseleko lwesekethe emfutshane,

inyama yenkomo ijerky eqhubekayo ivacuum yokupakisha inkqubo yokulawula umbane yekhonkco eliqhelekileyo lokukhusela. Xa i-motor winding kunye nokugqunyelelwa kocingo konakalisiwe, okanye izixhobo zokulawula ukusilela kunye nesekethe kumonakalo, umgca uya kubonakala isenzeko esifutshane sesekethe, sivelise isiphaluka esifutshane sangoku, ukuya kuthi ga kwishumi elinesibini lamaxesha angoku, yenza i-motor, umbane. izixhobo zombane, ucingo kunye nezinye izixhobo zombane umonakalo, ngoko kwimeko yesiphambeko sesekethe emfutshane, izixhobo zokukhusela zifuna inyathelo elikhawulezileyo, zinqumle ngokukhawuleza unikezelo lwamandla ombane oluqhelekileyo izixhobo zokhuseleko lwesekethe i-fuses kunye nezaphuli zesekethe. I-fuse iyanyibilika kwaye ikhuselwe isekethe kuthotho, xa umsebenzi oqhelekileyo wesekethe, i-fuse iyanyibilika ayisebenzi. Xa isiphaluka esifutshane, ubuninzi besiphaluka esifutshane sangoku sihamba ngokunyibilika, i-fuse yokunyibilika, ngoko nangoko kunqunyulwa amandla emoto. Ngokufanayo, ukuba kwisekethe eqhagamshelwe kwi-automatic air circuit breaker, xa i-short circuit, i-circuit breaker action ngoko nangoko, ukunqumla amandla okwenza i-motor stalling.



2, ukhuseleko lomthwalo ogqithisileyo,

inyama yenkomo ijerky eqhubekayo ivacuum yokupakisha inkqubo yokulawula umbane yekhonkco eliqhelekileyo lokukhusela. Xa ijerky yenkomo eqhubekayo yokupakisha umatshini wokupakisha umthwalo omkhulu kakhulu, ukuqala ukusebenza rhoqo okanye ukungabikho komsebenzi wesigaba, kunokwenza ukusebenza kwangoku kwemoto ixesha elide kunokulinganisa ngoku, ukufudumeza kwemoto, ukunyuka kweqondo lobushushu ngaphezu amaxabiso avumelekileyo, akhokelela kwi-insulation ye-motor brittle, ukunciphisa ubomi, kuya kwenza umonakalo wemoto. Ke ngoko, xa izixhobo zokukhusela ukugcwala kwemoto kufuneka zisebenze, zinqumle amandla okwenza imoto ingazinzi, uthintele imotor yomvundla phantsi kokusebenza okugqithisileyo.

isixhobo esiqhelekileyo sokukhusela umthwalo ogqithisiweyo sisilayidi esishushu. Xa umbane osebenzayo ulingana nomgangatho olinganisiweyo wemoto, i-thermal relay, umsebenzi oqhelekileyo wemoto; Ukugqithiswa kwexesha elifutshane okanye ukugqithiswa kwangoku xa i-motor incinci, intshukumo ye-thermal relay, okanye ingekho ixesha lokuthatha isenzo: xa i-motor overload yangoku inkulu, isenzo se-thermal relay, sinqumle isiphaluka solawulo kunye nesekethe eyintloko yobonelelo lwamandla, yenza i-motor. Ukuma, umzobo 34 usetyenziswa ekukhuselweni kwe-thermal relay overload.

kukhuseleko lwesigaba esivulekileyo semoto, ingasetyenziswa ngokukhuselwa kwesigaba esivulekileyo se-thermal relay ukufezekisa ukhuseleko lomthwalo ogqithisileyo. Kwinqanaba lesithathu le-asynchronous motor, ngokuqhelekileyo ibe lukhuselo olufutshane lwesekethe kunye nokhuseleko lomthwalo ogqithisiweyo.

I-3, ukhuseleko lwesigaba esivulekileyo

inyama yenkomo ijerky eqhubekayo ivacuum yokupakisha inkqubo yokulawula umbane yekhonkco eliqhelekileyo lokukhusela. Umatshini wokupakisha wenyama yenkomo eqhubekayo uvacuum unempazamo eyenzekayo, amandla enqanaba lesithathu le-asynchronous motor ngamanye amaxesha avela kwisigaba esivulekileyo, ukuba kukho isigaba esibini sokuqhawula umbane, i-motor yombane, okoko nje ubeke ingqalelo ekuthinteleni ukufumana ingozi yombane, ngokuqhelekileyo akukho ngozi. Ukuqhawulwa kombane, kodwa ukuba kuphela isigaba esinye semoto esinokubaleka, kodwa i-torque ye-torque yemoto incinci, ingozi yexesha lokugijima ithanda ukutshisa i-motor, ngaloo ndlela ukuvula ukhuseleko lwesigaba.



I-4, ngaphezulu kwangoku, ukhuseleko lwangoku oluphantsi

inyama yenkomo ijerky eqhubekayo ivacuum yokupakisha inkqubo yokulawula umbane yekhonkco eliqhelekileyo lokukhusela. I-beef jerky eqhubekayo yokupakisha umatshini wokupakisha ukhuseleko lwe-overcurrent luhluke kukhuseleko lohlobo lwangoku lokukhusela isiphaluka esifutshane. Ngaphezulu kwangoku, ibhekisa kwimotor okanye kumalungu ombane angaphezulu komgangatho wayo wokusebenza ngoku, idla ngokuba yincinci kunomji wesekethe emfutshane kwaye ayiphindaphindi kathandathu ireyithiwe yangoku. Kwimeko ye-overcurrent, amacandelo ombane awonakaliswa ngokukhawuleza, nje ngaphambi kokuba ukunyuka kweqondo lokushisa kuvunyelwe ngexabiso elikhulu langoku kunokuqalisa kwakhona okuqhelekileyo, kuvumelekile, kodwa umthwalo wempembelelo ogqithisileyo unokwenza i-motor ngokusebenzisa impembelelo yangoku ngokugqithisileyo, ukwenzela ukuba umonakalo imoto. Kakhulu ngaxeshanye, i-torque ye-electromagnetic yemoto inokwenza ukuba iindawo zothumelo lomatshini zonakaliswe, ngoko ke unqunyulwe umbane ngoko nangoko. Ubunokwenzeka bemisinga ye-eddy ekusebenzeni kwe-motor kwi-motor enkulu kune-short circuit iyenzeka, ngokukodwa kwi-startup rhoqo kunye ne-positive / ukuguqulwa, umsebenzi ophindaphindiweyo wexesha elifutshane ngokukodwa kwi-motor.
