Indlela yokukhetha i-contactor, izici okufanele zicatshangelwe lapho ukhetha i-contactor, nezinyathelo zokukhetha i-contactor

1. Lapho ukhetha i-aothintana naye, izici ezilandelayo zicatshangelwa ngokujulile.
①Isixhumi se-AC sisetshenziselwa ukusebenzisa umthwalo we-AC, futhi isixhumi se-DC sisetshenziselwa ukulayisha kwe-DC.
②Isikhathi sokusebenza esizinzile sephoyinti lokuxhumana eliyinhloko kufanele sibe sikhulu noma silingane nesamanje sesekethe yamandla okulayisha.Kufanele futhi kuqashelwe ukuthi ukusebenza okuzinzile kwephuzu lokuxhumana eliyinhloko le-contactor libhekisela kumanje ongasebenza ngokujwayelekile ngaphansi kwezimo ezithile (i-voltage emsebenzini wenani elilinganiselwe, uhlobo lohlelo lokusebenza, izikhathi zokusebenza zangempela, njll.).Uma izindinganiso ezithile zohlelo lokusebenza zihlukile, zamanje nazo zizoshintsha.
③ I-voltage ngesikhathi sokusebenza okuzinzile kwe-breaker circuit main kufanele ibe nkulu noma ilingane ne-voltage yesifunda samandla okulayisha.
④ I-voltage elinganiselwe yekhoyili kagesi kufanele ihambisane ne-control loop voltage.
2. Izinyathelo zokusebenza zokukhetha othintana naye.
①Uhlobo lwesixhumi kufanele lukhethwe ngokuya ngohlobo lomthwalo.
②Khetha amapharamitha amakhulu yenani elilinganiselwe le-contact.
Nquma amapharamitha ayinhloko yenani elilinganiselwe le-contactor, njenge-voltage, yamanje, amandla okukhiphayo, imvamisa, njll.
(1) I-electromagnetic coil voltage ye-contactor kufanele ngokuvamile ibe ngaphansi ukuze kuncishiswe izimfuneko zongqimba lwe-insulation ye-contactor futhi isebenzise ukuphepha okuhlobene.Uma i-loop yokulawula ilula futhi kunempahla embalwa yasendlini, i-voltage engu-380V noma engu-220V ingakhethwa ngokushesha.Uma isifunda samandla siyinkimbinkimbi kakhulu.Uma isamba senani lezinto zikagesi zasendlini ezisetshenzisiwe lingaphezu kuka-5, 36V noma 110V amakhoyili we-voltage solenoid angakhethwa ukuze kuqinisekiswe ukuphepha.Kodwa-ke, ukuze kube lula futhi kuncishiswe imishini nemishini, ukukhetha kuvame ukwenziwa ngokuya nge-voltage ethile yegridi yamandla.
(2) Imvamisa yokusebenza yemoto ayiphezulu, njengama-compressor esiqandisini, amaphampu amaphakathi, amafeni aphakathi nendawo, ama-air conditioner aphakathi, njll., umthamo wamanje okaliwe we-contactor udlula umthamo okaliwe womthwalo.
(3) Kumamotho omsebenzi angesindo wansuku zonke, njengenjini eyinhloko yamalebula e-CNC, izinkundla zokuphakamisa, njll., ihora elilinganiselwe le-contactor lidlula imanje elilinganiselwe lenjini lapho likhethiwe.
(4) Izimoto ngezinjongo eziyinhloko eziyingqayizivele.Ngokuvamile lapho ukusebenza kuphendukile, othintana naye angakhethwa ngokuya nempilo yesevisi yemishini kagesi kanye nenani lokugijima kwamanje, i-CJ10Z.CJ12.
(5) Uma usebenzisa i-contactor ukulawula i-transformer, ubukhulu be-voltage yokuqhuma kufanele kucatshangelwe.Isibonelo, imishini yokushisela i-DC ingakhetha othintana nabo ngokusekelwe kabili isilinganiso samanje se-transformer, njenge-CJT1.CJ20 njalonjalo.
(6) I-current elinganiselwe ye-contactor ibhekisela kumthamo omkhulu ovunyelwe we-contactor ngesikhathi sokusebenza isikhathi eside, isikhathi sokulibaziseka singaphansi noma silingana no-8h, futhi sifakwe kwisilawuli esivulekile.Uma isimo sokupholisa singesihle, umthamo olinganisiwe we-contactor kufanele ukhethwe ngokuvumelana nezikhathi ezingu-1.1-1.2 zamanje ezilinganiselwe zomthwalo.
(7) Khetha inani eliphelele kanye nohlobo lwabaxhumene nabo.Inani eliphelele kanye nohlobo loxhumana nabo kufanele bahlangabezane nemithetho yesifunda sokulawula.
