1. Lapho ukhetha i-contactor, indawo yokusebenza kufanele icatshangelwe, futhi izici ezilandelayo kufanele zicatshangelwe.
①I-AC contactor kufanele isetshenziselwe ukulawula umthwalo we-AC, futhi i-DC contactor kufanele isetshenziselwe ukulayishwa kwe-DC.
② Isilinganiso sokusebenza samanje sothintana naye oyinhloko kufanele sibe sikhulu noma silingane nesamanje sesekethe yomthwalo.Kufanele futhi kuqashelwe ukuthi ukusebenza okulinganiselwe kokuxhumana okuyinhloko kothintana naye kujwayelekile ngaphansi kwezimo ezishiwo (i-voltage elinganiselwe yokusebenza, isigaba sokusetshenziswa, imvamisa yokusebenza, njll.) Inani lamanje lokusebenza, lapho izimo zokusetshenziswa zangempela zihlukile, inani lamanje nalo lizoshintsha ngokufanele.
③ I-voltage elinganiselwe yokusebenza yothintana naye oyinhloko kufanele ibe nkulu noma ilingane ne-voltage yesekethe yomthwalo.
④I-voltage elinganiselwe yekhoyili kufanele ihambisane ne-control loop voltage
2. Izinyathelo eziqondile zokukhetha othintana naye
①Khetha uhlobo lwe-contactor, udinga ukukhetha uhlobo loxhumana naye ngokuya ngohlobo lomthwalo
②Khetha imingcele elinganiselwe yesixhumi
Ngokusho kwento elawulwayo kanye nemingcele yokusebenza, njenge-voltage, yamanje, amandla, imvamisa, njll., nquma imingcele elinganiselwe ye-contactor.
(1) I-voltage yekhoyili yesixhumi esithintayo ngokuvamile kufanele ibe ngaphansi, ukuze izidingo zokuvala izinsimbi zehliswe futhi kuphephe kakhudlwana ukuzisebenzisa.Uma isifunda sokulawula silula futhi izinto zikagesi zincane, i-voltage engu-380V noma i-220V ingakhethwa ngokuqondile.Uma isifunda siyinkimbinkimbi.Uma inani lezinto zikagesi lingaphezu kuka-5, amakhoyili ane-voltage engu-36V noma engu-110V angakhethwa ukuze kuqinisekiswe ukuphepha.Kodwa-ke, ukuze kube lula futhi kuncishiswe imishini, kuvame ukukhethwa ngokuya nge-voltage yegridi yangempela.
(2) Imvamisa yokusebenza yemoto ayiphezulu, njengama-compressor, amaphampu amanzi, amafeni, ama-air conditioner, njll., ukulinganisa kwamanje kwe-contactor kukhulu kunomthamo olinganiselwe womthwalo.
(3) Kumamotho esindayo, njengenjini eyinhloko yamathuluzi omshini, izinto zokuphakamisa, njll., umthamo wamanje olinganiselwe we-contactor mkhulu kunowamanje olinganiselwe wenjini.
(4) Ngenhloso ekhethekile izinjini.Uma ivame ukugijima esimweni sokuqala nokuhlehla, i-contactor ingakhethwa cishe ngokuvumelana nempilo kagesi kanye nokuqala kwamanje.CJ10Z, CJ12,
(5) Uma usebenzisa i-contactor ukulawula i-transformer, ubukhulu be-inrush current kufanele bucatshangelwe.Isibonelo, emishini yokushisela kagesi, othintana nabo bangakhethwa ngokuphindwe kabili isilinganiso samanje se-transformer, njenge-CJT1, CJ20, njll.
(6) Umthamo wamanje olinganiselwe we-contactor ubhekisela kumkhawulo wamanje ovunyelwe we-contactor ngaphansi kokusebenza kwesikhathi eside, ubude besikhathi ngu-≤8H, futhi ifakwe kuphaneli yokulawula evulekile.Uma isimo sokupholisa singesihle, lapho i-contactor ikhethiwe, i-current rated of the contactor izoba I-current ikhethwa ngokuvumelana nezikhathi ezingu-1.1-1.2 zamanje ezilinganiselwe zomthwalo.
(7) Khetha inombolo kanye nohlobo loxhumana nabo.Inombolo kanye nohlobo loxhumana nabo kufanele luhlangabezane nezimfuneko zesifunda sokulawula.
