Abafowunelwa be-ACzahlulwe zaba zidibanisi be-AC (i-voltage esebenzayo AC) kunye nee-DC zoqhagamshelwano (i-voltage DC), ezisetyenziswa kubunjineli bamandla, izixhobo zokuhambisa amandla kunye neendawo zobunjineli bamandla.Umnxibelelanisi we-AC ngokwethiyori ubhekisa kwisixhobo sasekhaya esisebenzisa ikhoyili ukwenza intsimi ye-electromagnetic ngokwesixa semveliso yangoku yokuvelisa ukucima isinxibelelanisi se-AC ukulawula umthwalo.
Umnxibelelanisi we-AC sisitshixo samandla kunye nolawulo lwesekethe edla ngokusetyenziswa njengonikezelo lombane lokutshintsha.Isebenzisa indawo yoqhagamshelwano ephambili ukuvula kunye nokucima isiphaluka samandla, kwaye isebenzisa indawo yoqhagamshelwano encedisayo ukuphumeza ulawulo lweprogram.Umgangatho woqhagamshelwano oyintloko ngokuqhelekileyo unomsebenzi wokuvula kunye nokuvala ukudibanisa, kunye neendawo zokudibanisa ezincedisayo ngokuqhelekileyo zinezibini ezimbini zokudibanisa kunye nemisebenzi yokuvula nokuvala kwaye ngokuqhelekileyo ivalwe.Abafowunelwa abancinci be-AC badla ngokusetyenziswa njengeelayidi ezincinci kunye neesekethe zamandla eziphambili.Indawo yoqhagamshelwano ye-AC ye-contactor yenziwe nge-alloy yesilivere-tungsten, ene-conductivity elungileyo yombane kunye nokumelana nokuqhekeka kwe-thermal.
I-DC contactor yi-AC yoqhagamshelwano esetyenziswa kwisekethe ye-DC.Ihambelana ne-AC contactor kwaye ngokuqhelekileyo inomphezulu woqhagamshelwano oyintloko.Ncedisa ngeendawo zoqhagamshelwano kunye neendawo zoqhagamshelwano ngekhoyili.Thatha i-DC contactor eboniswe kumfanekiso njengomzekelo.Yamkela i-modularization kwaye inokudibanisa iindlela zokuthintela kunye neendlela zokuthintela ezifunwa ngabathengi (ngokuqhelekileyo zivuliwe, zihlala zivaliwe kwaye zitshintshiwe);olu chungechunge lwemveliso lunokutshintshwa kwamandla ombane aphezulu kunye nenqanaba lokuvuthela i-electromagnetic field arc ecimayo, amandla ombane aphezulu ombane osebenzayo anokufikelela kwi-220VDC.Le mveliso ilungele inkqubo yolawulo lokutshintsha unikezelo lwamandla okanye isoftware yenkqubo yamandla, iforklift yombane, amandla amatsha ombane wokwakhiwa kwezixhobo zesoftware.
Iimpawu zesakhiwo kunye nemigaqo yabafowunelwa be-DC ngokusisiseko ziyafana nezo ze-AC zoqhagamshelwano, kwaye zikwaqulunqwe ngumbutho wokungeniswa kwe-electromagnetic, isoftware yenkqubo yokuchukumisa kunye nezixhobo zokucima i-arc, kodwa umbutho wokungeniswa kwe-electromagnetic wahlukile.
Ngokubanzi, umahluko phakathi kwesakhiwo DC contactor kunye AC contactor kuxhomekeke: intsimbi core coil akukho lula ukuba kubangele eddy kunye eddy ilahleko yangoku umonakalo ngokungqinelana nombane DC, ngoko akukho lula ukuba shushu.Ukuze kube lula ukuququzelela ukuveliswa kunye nokucubungula, i-iron core yenziwe ngayo yonke intsimbi ethambileyo.Ukuze ngcono ukwenza coil ubushushu dissipation encomekayo, ikhoyili idla inxeba kwimilo obhityileyo cylindrical, leyo ngqo uqhagamshelane core yentsimbi, nto leyo kulula kakhulu ukutshabalalisa ubushushu.Makhe sijonge umahluko ezine phakathi abafowunelwa DC kunye nabafowunelwa AC.
Umahluko ophambili yi-AC contactor kunye ne-DC contactor.
1. Intsimbi yentsimbi ihluke: intsimbi yentsimbi ye-AC contactor iya kubangela umonakalo we-eddy kunye ne-eddy yangoku, ngelixa i-DC contactor ayinayo umonakalo wentsimbi.Ngoko ke, intsimbi yentsimbi ye-AC contactor yenziwe ngamacwecwe ensimbi ye-silicon kunye neengqimba ezikhuselayo, ngokuqhelekileyo i-E-shaped;undoqo wentsimbi ye-DC contactor yenziwe ngayo yonke intsimbi ethambileyo, uninzi lwazo lumilise ngo-U.
2. Isofthiwe yenkqubo yokucima i-arc yahlukile: izixhobo zokucima i-arc yegridi zikhethwa kwi-AC contactor, kunye nesixhobo sokucima i-arc yokucima imagnethi sikhethwa kwi-DC contactor.
3. Inani lekhoyili lijika lihlukile: inani le-coil lijika le-AC contactor lincinci, inani lokujika kwe-DC contactor coil lixhaphake kakhulu kwi-DC power supply, i-AC contactor yahlulwe kwisekethe ye-AC, kunye ne-DC contactor yahlulwe yaba yisekethe ye-DC.
4. I-frequency yangempela yokusebenza ihluke: i-AC contactor inomsebenzi omkhulu wokusebenza, ubuninzi ngamaxesha angama-600 / iyure, kwaye isicelo siphantsi kweendleko.Umnxibelelanisi we-DC unokufikelela amaxesha angama-2000 / iyure, kwaye iindleko zesicelo ziphezulu.
Ngaba abafowunelwa be-AC kunye nabafowunelwa be-DC banokutshintshwa?
1. I-AC contactor ingasetyenziswa kwi-DC contactor ngexesha likaxakeka, kwaye ixesha lokutsala alikwazi ukudlula iiyure ze-2 (kuba ukutshatyalaliswa kobushushu be-AC coil kubi kakhulu kune-DC, elele kwisakhiwo sayo esahlukileyo) .Kungcono ukudibanisa ukuchasana kuchungechunge kunye nekhoyili ye-AC, kodwa i-DC ayinakuthatha indawo ye-AC contactor;
2. Inani lokujika kwe-coil ye-AC contactor lincinci, kwaye inani lokujika kwe-coil ye-DC contactor inkulu.Xa i-current of the main power circuit inkulu kakhulu (IE250A), i-AC contactor isebenzisa i-series-connected double-winding coil;
3. I-DC relay coil resistor inkulu kwaye yangoku incinci.Ukuba ayitshatyalaliswa ngokulula ngokuqhagamshela kumbane we-AC, nceda uyibeke kwangoko.Nangona kunjalo, i-coil ye-automobile relay coil ine-resistor encinci kunye nenani elikhulu langoku.Ukuba iqhagamshelwe kumbane olawulwa yi-DC, ikhoyili iya kutshatyalaliswa;
4. Inani lokujika kwe-coil ye-AC ye-contactor encinci kwaye i-resistor incinci.Xa i-coil ingena kwi-alternating current, kuya kubakho ukuxhatshazwa okukhulu kwe-magnetic induction friction, edlula kakhulu ukuchasana kwekhoyili.Isitshixo kumandla okuvuselela i-coil ubukhulu be-magnetic induction friction resistance.Ukuba i-DC yangoku ibinokuqukuqela ngaphakathi, i-coil iya kuba ngumthwalo ochasayo.Ngeli xesha, inani langoku elidlulayo kwikhoyili liya kuba likhulu kakhulu, okwenza ikhoyili ishushu okanye itshise.Ke ngoko, abafowunelwa be-AC abanakusetyenziswa njengabafowunelwa beDC.
