Ukuvula ngokuSebenzayo kunye noKhuseleko: Amandla e-Thermal Relays kunyeUkuhanjiswa kwe-Thermal Overload
Kwimeko ehlala iguquka ye-industrial automation kunye nobunjineli bombane, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle koomatshini kubaluleke kakhulu. Ngena amagorha angazange abonwe kwihlabathi lombane: iireyilayi ze-thermal kunye ne-thermal overload relays. Ezi zixhobo, nangona zihlala zingahoywa, zidlala indima ebalulekileyo ekukhuseleni iinjini kunye nezinye izixhobo zombane emonakalweni ngenxa yobushushu obugqithisileyo. Kule bhlog, siza kugocagoca ngokubaluleka kwala macandelo, imigaqo yawo yokusebenza, kwaye kutheni eyimfuneko kwizicelo zale mihla zemizi-mveliso.
Ukuqonda i-Thermal Relays kunye ne-Thermal Overload Relays
Embindini wabo, i-thermal relays kunye ne-thermal overload relays ziyilelwe ukukhusela iisekethe zombane ukusuka kumbane ogqithisileyo onokuthi ukhokelela ekugqithiseni kunye nomonakalo onokwenzeka. I-relay ye-thermal sisixhobo sokukhusela esisebenza ngokusekelwe kubushushu obuveliswa ngumbane ohamba kuyo. Xa umsinga udlula inqanaba elimiselweyo, ubushushu obuveliswayo bubangela ukuba i-relay ihambe, ngaloo ndlela iphazamise isekethe kwaye ithintele umonakalo ongakumbi.
Kwelinye icala, i-thermal overload relay luhlobo oluthile lwe-thermal relay esetyenziswa ngokuyintloko ukukhusela iimotor ekutshiseni kakhulu. IiMotor ngamahashe okusebenza koomatshini bemizi-mveliso, kwaye ukusebenza kwabo okuqhubekayo ngamanye amaxesha kunokukhokelela ekwakhekeni kobushushu obugqithisileyo. I-thermal overload relay ijonga ubushushu bemoto kwaye ijikeleza isekethe ukuba iqondo lobushushu lingaphezulu komda okhuselekileyo. Oku akuthinteli kuphela umonakalo kwi-motor kodwa kwakhona kuqinisekisa ukhuseleko lwenkqubo yonke.
Umgaqo oSebenzayo: I-Symphony yoBubushushu kunye noBuchule
Ukusebenza kwe-thermal relays kunye ne-thermal overload relays yintsebenziswano enomdla yobushushu kunye nentshukumo yomatshini. Ezi zixhobo ngokuqhelekileyo ziquka i-bimetallic strip, eyenziwe ngeentsimbi ezimbini ezahlukeneyo kunye ne-coefficients eyahlukileyo yokwandiswa kwe-thermal. Xa i-current ihamba nge-relay, i-bimetallic strip iyatshisa kwaye igobe ngenxa yokwandiswa kwamazinga eentsimbi. Esi senzo sokugoba sibangela umatshini womatshini ovula isiphaluka, ngaloo ndlela uphazamise ukuhamba kwangoku.
Kwimeko ye-thermal overload relays, i-bimetallic strip ihlala idityaniswa kunye ne-heater element edibana ngqo ne-motor. Njengoko i-motor isebenza, into yokufudumala iyafudumala, ibangela ukuba i-bimetallic strip igobe. Ukuba ubushushu bemoto bunyuke ngaphaya komda okhuselekileyo, umcu ugoba ngokwaneleyo ukuba ukhubekise isilayidi, unqumle unikezelo lwamandla kwinjini. Le ndlela ilula kodwa esebenzayo iqinisekisa ukuba i-motor ikhuselwe ekutshiseni ngokugqithisileyo, ngaloo ndlela yandisa ubomi bayo kunye nokunciphisa iindleko zokuyigcina.
Kutheni i-Thermal Relays kunye ne-Thermal Overload Relays ziyimfuneko
Ukubaluleka kwe-thermal relays kunye ne-thermal overload relays ayikwazi ukugqithiswa. Kwiimeko zemizi-mveliso, apho oomatshini basebenza ngokuqhubekayo kwaye kaninzi phantsi kwemithwalo enzima, umngcipheko wokushisa ogqithiseleyo uhlala ukhona. Ngaphandle kwezi zixhobo zokukhusela, iimotor kunye nezinye izixhobo zombane ziya kuba sesichengeni sokonakala, okukhokelela kulungiso oluxabisa kakhulu kunye nexesha lokuphumla. Ngokubandakanya ukuhanjiswa kwe-thermal kunye ne-thermal overload relays kwiinkqubo zabo, amashishini anokuqinisekisa ixesha elide kunye nokuthembeka koomatshini babo.
Ngaphezu koko, ezi zixhobo zinegalelo kukhuseleko jikelele emsebenzini. Ukushisa okugqithisileyo akunakonakalisa kuphela izixhobo kodwa kunokubangela ingozi yomlilo. Ukuhanjiswa kwe-thermal kunye ne-thermal overload relays zisebenza njengomgca wokuqala wokukhusela, ukuthintela ukufudumala kunye nokunciphisa umngcipheko womlilo. Oku kubaluleke kakhulu kumashishini apho izinto ezinokutsha zikhona, kwaye ukhuseleko luyiyona nto iphambili.
Ukukhetha iRelay ye-Thermal eLungileyo kunye ne-Thermal Overload Relay
Ukukhetha i-relay efanelekileyo ye-thermal okanye i-thermal overload relay kwisicelo sakho kubalulekile ekuqinisekiseni ukusebenza kakuhle kunye nokhuseleko. Izinto ekufuneka ziqwalaselwe ziquka ukulinganisa kwangoku, uhlobo lwemoto okanye isixhobo esikhuselweyo, kunye nendawo yokusebenza. Kwakhona kubalulekile ukukhetha ukuhanjiswa kunye neklasi yohambo olufanelekileyo, olumisela ukuba i-relay iya kuphendula ngokukhawuleza kangakanani imeko yokulayisha ngaphezulu.
Abavelisi abaninzi abahloniphekileyo banikezela ngoluhlu olubanzi lwe-thermal relays kunye ne-thermal overload relays, nganye yenzelwe ukuhlangabezana neemfuno ezithile.
