1. Xa ukhetha i-contactor, indawo yokusebenza kufuneka ithathelwe ingqalelo, kwaye ezi zinto zilandelayo kufuneka ziqwalaselwe.
①Isinxibelelanisi se-AC kufuneka sisetyenziswe ukulawula umthwalo we-AC, kwaye i-DC contactor kufuneka isetyenziswe kumthwalo we-DC.
② Umlinganiselo osebenzayo osebenzayo womnxeba oyintloko kufuneka ube mkhulu okanye ulingane nombane wesiphaluka somthwalo.Kufuneka kwakhona kuqatshelwe ukuba umlinganiselo osebenzayo osebenzayo womnxeba oyintloko we-contactor uqhelekile phantsi kweemeko ezichaziweyo (i-voltage yokusebenza elinganisiweyo, udidi lokusetyenziswa, i-frequency yokusebenza, njl.) Ixabiso langoku elisebenzayo, xa iimeko zokusetyenziswa zangempela zihlukile, ixabiso langoku nalo liya kutshintsha ngokufanelekileyo.
③ Umbane olinganisiweyo osebenzayo womnxeba oyintloko kufuneka ube mkhulu okanye ulingane nombane wesekethe yomthwalo.
④I-voltage elinganisiweyo yekhoyili kufuneka ihambelane ne-voltage loop yokulawula
2. Amanyathelo athile okukhetha umnxibelelanisi
①Khetha uhlobo lomfowunelwa, kufuneka ukhethe uhlobo lomfowunelwa ngokohlobo lomthwalo
②Khetha iiparamitha ezirethiweyo zomfowunelwa
Ngokwento elawulwayo kunye neeparitha zokusebenza, ezifana ne-voltage, okwangoku, amandla, i-frequency, njl., misela iiparitha ezilinganisiweyo zoqhagamshelwano.
(1) I-voltage yekhoyili yesiqhagamshelo kufuneka ibe sezantsi ngokubanzi, ukuze iimfuno zokugquma komqhagamshelwa zincitshiswe kwaye kukhuseleke ngakumbi ukuzisebenzisa.Xa isiphaluka solawulo silula kwaye izixhobo zombane zincinci, i-voltage ye-380V okanye i-220V inokukhethwa ngokuthe ngqo.Ukuba isiphaluka sinzima.Xa inani lezixhobo zombane lidlula i-5, iikhoyili ezine-36V okanye i-110V yombane zingakhethwa ukuqinisekisa ukhuseleko.Nangona kunjalo, ukuze kuququzelelwe kwaye kuncitshiswe izixhobo, ihlala ikhethwa ngokweyona ndlela yombane wegridi.
(2) I-frequency yokusebenza ye-motor ayikho phezulu, njengama-compressors, iimpompo zamanzi, iifeni, i-air conditioners, njl.
(3) Kwiimoto ezinzima, ezifana neyona nto iphambili yezixhobo zoomatshini, izixhobo zokunyusa, njl.
(4) Ngenjongo ekhethekileyo yeenjini.Xa ihlala iqhuba kwimeko yokuqala kunye nokubuyisela umva, i-contactor ingakhethwa ngokufanelekileyo ngokuhambelana nobomi bombane kunye nokuqala ngoku.CJ10Z, CJ12,
(5) Xa usebenzisa i-contactor ukulawula i-transformer, ubukhulu be-inrush current kufuneka buqwalaselwe.Ngokomzekelo, kumatshini we-welding yombane, abafowunelwa ngokubanzi banokukhethwa ngokuphindaphindiweyo ngokuphindwe kabini okwangoku kwe-transformer, njenge-CJT1, i-CJ20, njl.
(6) Umbane olinganisiweyo we-contactor ubhekisela kumandla aphezulu avumelekileyo oqhagamshelwano phantsi kokusebenza kwexesha elide, ubude bexesha ≤8H, kwaye ifakwe kwipaneli yokulawula evulekileyo.Ukuba imeko yokupholisa ihlwempuzekile, xa i-contactor ikhethiweyo, i-current rated current of the contactor iya kuba I-current ikhethwe ngokuhambelana ne-1.1-1.2 amaxesha okulinganisa ngoku komthwalo.
(7) Khetha inombolo kunye nodidi lwabafowunelwa.Inombolo kunye nohlobo lwabafowunelwa kufuneka luhlangabezane neemfuno zesiphaluka solawulo.
