Izixhumi ze-ACihlukaniswe yaba ama-AC contactors (i-voltage esebenzayo AC) kanye ne-DC contactors (voltage DC), asetshenziswa kubunjiniyela bamandla, okokusebenza kokusabalalisa amandla kanye nezindawo zobunjiniyela bamandla.Isixhumi se-AC ngokuyisisekelo sibhekisela kumshini wasendlini osebenzisa ikhoyili ukuze wakhe inkambu kazibuthe ngokwenani lokukhiqizwa kwemboni yamanje ukuvala isixhumi se-AC ukulawula umthwalo.
I-AC contactor iwukushintsha amandla kanye nesekethe yokulawula evame ukusetshenziswa njengomthombo wamandla okushintshayo.Isebenzisa indawo yokuxhumana eyinhloko ukuvula nokuvala isekethe yamandla, futhi isebenzisa indawo yokuxhumana eyinsiza ukuze iqalise ukulawula uhlelo.Indawo yokuxhumana eyinhloko ngokuvamile inezindawo zokuthintana zokuvula nokuvala kuphela, futhi indawo yokuxhumana eyinsiza ngokuvamile inamapheya amabili ezindawo zokuthintana ezinemisebenzi yokuvula nokuvala nokuvamise ukuvaleka.Izixhumi ze-AC ezincane zivame ukusetshenziswa njengama-relay amancane namasekhethi amakhulu wamandla.Indawo yokuxhumana ye-AC contactor yenziwe nge-silver-tungsten alloy, ene-conductivity kagesi enhle kanye nokumelana nokuqhekeka okushisayo.
I-DC contactor iyisixhumi se-AC esisetshenziswa kusekethe ye-DC.Ifana nesixhumi se-AC futhi ngokuvamile inendawo yokuxhumana eyinhloko.Siza ngokuthintana nendawo okuthintana ngayo namakhoyili.Thatha i-DC contactor eboniswe esithombeni njengesibonelo.Isebenzisa i-modularization futhi ingahlanganisa izindlela zokuthinta nezindlela zokuthinta ezidingwa amakhasimende (ngokuvamile kuvuliwe, kuvame ukuvalwa futhi kushintshwe);lolu chungechunge lomkhiqizo lunomshini wokushisa ophezulu wokuthinta amandla okusebenza kagesi kanye nezinga elivunguza i-arc yensimu ye-electromagnetic, amandla aphezulu okushintsha amandla kagesi angafinyelelwa ku-220VDC.Lo mkhiqizo ulungele ukulawulwa kwesistimu ukushintsha ukunikezwa kwamandla noma isofthiwe yesistimu yamandla aphezulu, i-forklift kagesi, isofthiwe yesistimu yemishini yokwakhiwa kwemoto kagesi entsha.
Izici zesakhiwo nemigomo yabathintana naye be-DC ngokuyisisekelo ziyefana nalezo zoxhumana nabo be-AC, futhi zakhiwe nenhlangano yokungeniswa kukagesi kagesi, isoftware yesistimu yokuthinta kanye nemishini yokucisha i-arc, kodwa inhlangano yokungeniswa kwe-electromagnetic ihlukile.
Ngokuvamile, umehluko phakathi kwesakhiwo se-DC contactor kanye ne-AC contactor incike kulokhu: ikhoyili yensimbi eyinhloko akulula ukubangela ukulimala kwamanje kwe-eddy ne-eddy ngokusho kwamandla kagesi we-DC, ngakho-ke akulula ukushisa.Ukuze kube lula ukukhiqiza nokucubungula kangcono, umgogodla wensimbi wenziwa ngayo yonke insimbi emnene.Ukuze wenze kangcono ukuchithwa kokushisa kwekhoyili kuhle kakhulu, ikhoyili ivame ukulinyazwa ibe umumo omncane we-cylindrical, othintana ngqo nomgogodla wensimbi, okulula kakhulu ukuchithwa kokushisa.Ake sibheke umehluko omine phakathi koxhumana nabo be-DC kanye nezixhumi ze-AC.
Umehluko oyinhloko yi-AC contactor kanye ne-DC contactor.
1. I-iron core ihlukile: i-iron core ye-AC contactor izobangela ukulimala kokulahlekelwa kwamanje kwe-eddy ne-eddy, kuyilapho i-DC contactor ingenawo umonakalo we-iron core.Ngakho-ke, umgogodla wensimbi we-AC contactor wakhiwa amapuleti ensimbi e-silicon anezendlalelo ezivikelayo, ngokuvamile ezimise okwe-E;umgogodla wensimbi we-DC contactor wenziwe ngayo yonke insimbi ethambile, iningi layo elimise u-U.
2. Isofthiwe yesistimu yokucima i-arc ihlukile: imishini yokucima i-arc yegridi ikhethelwa isixhumi se-AC, futhi idivayisi yokucima i-arc evuthelayo ikhethelwa isixhumi se-DC.
3. Inani lokuphenduka kwekhoyili lihlukile: inombolo yokujika ikhoyili ye-AC contactor incane, inani lokuphenduka kwekhoyili ye-DC contactor livame kakhulu kugesi we-DC, i-AC contactor ihlukaniswe yaba yisekethe ye-AC, futhi i-DC contactor ihlukaniswe isekethe ye-DC.
4. Imvamisa yokusebenza yangempela ihlukile: i-AC contactor ine-current enkulu yokusebenza, umkhawulo uyizikhathi ze-600 / ihora, futhi isicelo singabizi kakhulu.I-DC contactor ingafinyelela izikhathi ezingu-2000/ihora, futhi izindleko zohlelo lokusebenza ziphakeme kakhulu.
Ingabe oxhumana nabo be-AC nabathintana nabo be-DC bangashintshwa?
1. I-AC contactor ingasetshenziswa ku-DC contactor esimweni esiphuthumayo, futhi isikhathi sokudonsa asikwazi ukudlula amahora angu-2 (ngoba ukuchithwa kokushisa kwekhoyili ye-AC kubi kakhulu kune-DC, elele esakhiweni sayo esihlukile) .Kungcono ukuxhuma ukumelana nochungechunge ngekhoyili ye-AC, kodwa i-DC ayikwazi ukufaka esikhundleni se-AC contactor;
2. Inani lokuphenduka kwekhoyili ye-AC contactor lincane, futhi inani lamajika ekhoyili ye-DC contactor likhulu.Lapho i-current of main power circuit inkulu kakhulu (IE250A), isixhumi se-AC sisebenzisa uchungechunge oluxhunywe ikhoyili enamawindi amabili;
3. I-DC relay coil resistor inkulu futhi yamanje incane.Uma ingashabalali kalula ngokuxhuma amandla e-AC, sicela uyibeke ngokushesha.Nokho, ikhoyili ye-AC automobile relay ine-resistor encane kanye nenani elikhulu lamanje.Uma ixhunywe kugesi olawulwa yi-DC, ikhoyili izobhujiswa;
4. Inani lokuphenduka kwekhoyili ye-AC contactor lincane futhi isixhasi sincane.Lapho ikhoyili ingena kumanje oshintshanayo, kuzoba nokumelana okukhulu kwe-magnetic induction friction, okudlula kude ukumelana kwekhoyili.Isihluthulelo samandla avusa amadlingozi wekhoyili ubukhulu bokumelana nokungqubuzana kokufakwa kukazibuthe.Uma i-DC ingena ngaphakathi, ikhoyili ingaba umthwalo oqinile.Ngalesi sikhathi, inani lamanje elidlula ikhoyili lizoba likhulu kakhulu, okwenza ikhoyili ishise noma ishise.Ngakho-ke, oxhumana nabo be-AC abakwazi ukusetshenziswa njengabaxhumanisi be-DC.
