1. Lapho ukhetha i-contactor, qala endaweni yokusebenza, futhi ikakhulukazi ucabangele izici ezilandelayo
Izixhumi ze-AC zizokhethelwa ① ukulawula umthwalo we-AC nezixhumi ze-DC zokulayisha kwe-DC
Isilinganiso sokusebenza samanje ② othintana naye oyinhloko kufanele sibe sikhulu noma silingane nesamanje sesekhethi yomthwalo, futhi uqaphele ukuthi ukusebenza okulinganiselwe kothintana naye oyinhloko kungaphansi kwezimo ezishiwo (i-voltage yokusebenza elinganiselwe, isigaba sokusebenzisa, ukusebenza imvamisa, njll.) ingasebenza ngevelu evamile yamanje, lapho izimo zokusetshenziswa zangempela zihlukile, inani lamanje nalo lizoshintsha ngokufanele.
I-voltage elinganiselwe yokusebenza yokuxhumana okuyinhloko ③ izoba nkulu kunaleyo yesekethe yomthwalo.
I-voltage elinganiselwe yekhoyili engu-④ kufanele ihambisane ne-voltage yesekethe yokulawula
2. Izinyathelo eziqondile zokukhetha othintana naye
① ikhetha uhlobo lwesixhumi, edinga uhlobo lwesixhumi esisuselwe kuhlobo lomthwalo
I-② ikhetha ipharamitha elinganiselwe yesixhumi
Nquma amapharamitha alinganiselwe we-contactor ngokuya ngento eshajiwe kanye nemingcele yokusebenza, njenge-voltage, yamanje, amandla, imvamisa, njll.
(1) I-voltage yekhoyili yesixhumi esithintayo kufanele ngokuvamile ibe ngaphansi, ukuze izidingo zokuvikela zekhoyili zehliswe, futhi iphephe uma isetshenziswa.Uma isifunda sokulawula silula futhi ukusetshenziswa kwezinto zikagesi kuncane, i-voltage engu-380V noma engu-220V ingakhethwa ngokuqondile.Uma isifunda siyinkimbinkimbi.Uma inani lezinto zikagesi ezisetshenzisiwe lingaphezu kuka-5, ikhoyili kagesi engu-36V noma engu-110V ingasetshenziswa ukuze kuqinisekiswe ukuphepha.Kodwa ukuze kube lula futhi kuncishiswe imishini, ngokuvamile ngokuya ngokukhetha kwangempela kwegridi yamandla kagesi.
(2) Imvamisa yokusebenza kwenjini ayiphezulu, njenge-compressor, iphampu yamanzi, isiphephetha-moya, isimo somoya, njll., umthamo wamanje olinganiselwe we-contactor mkhulu kunomthwalo okalwe wamanje.
(3) Enjinini yohlobo lomsebenzi esindayo, njengenjini eyinhloko yamathuluzi omshini, izinto zokuphakamisa, njll., imanje elilinganiselwe le-contactor likhulu kunelamanje elilinganiselwe lemoto.
(4) Ngenhloso ekhethekile izinjini.Lapho kuvame ukusebenza esimweni sokuqala nokuhlehla, i-contactor ingakhethwa cishe ngokuya nempilo kagesi kanye nokuqala kwamanje, ongakukhetha kwe-CJ10Z, CJ12,
(5) Lapho ulawula i-transformer nge-contactor, umshini wokushisa kufanele ucatshangelwe.Isibonelo, umshini wokushisela kagesi ungakhetha ngokuvamile othintana nabo ngezikhathi ezi-2 zamanje ezilinganiselwe ze-transformer, njenge-CJT1, CJ20, njll.
(6) Umthamo wamanje olinganiselwe we-contactor ubhekisela kumkhawulo wamanje ovumelekile we-contactor ngaphansi komsebenzi wesikhathi eside, nobude be-8H, futhi ufakwe ebhodini lokulawula elivulekile.Uma isimo sokupholisa singesihle, umthamo olinganisiwe we-contactor ukhethwa izikhathi ezingu-1.1-1.2 zamanje ezilinganiselwe zomthwalo lapho kukhethiwe.
(7) Khetha inombolo kanye nohlobo loxhumana nabo.Inombolo nohlobo loxhumana nabo lizohlangabezana nezimfuneko zesekhethi yokulawula.
