1. Xa ukhetha i-contactor, qalisa ukusuka kwindawo yokusebenza, kwaye ngokukodwa ukuqwalasela ezi zinto zilandelayo
Abaqhagamsheli be-AC baya kukhethelwa ① ukulawula umthwalo we-AC kunye nabafowunelwa be-DC kumthwalo we-DC
Umgangatho osebenzayo wangoku we-② umfowunelwa oyintloko kufuneka ube mkhulu okanye ulingane nangoku wesekethe yomthwalo, kwaye uqaphele ukuba ukusebenza okulinganiselweyo koqhagamshelwano oluphambili loqhagamshelwano luphantsi kweemeko ezichaziweyo (i-voltage elinganisiweyo yokusebenza, udidi losetyenziso, ukusebenza. i-frequency, njl.
Amandla ombane osebenzayo olinganisiweyo we-③ uqhagamshelwano oluphambili luya kuba lukhulu kunolo lwesekethe yomthwalo.
Umbane olinganisiweyo we-coil ④ uya kuhambelana nombane wesiphaluka solawulo
2. Amanyathelo athile okukhetha umnxibelelanisi
① ikhetha uhlobo loqhagamshelwano, ifuna uhlobo lomfowunelwa olusekwe kuhlobo lomthwalo
I-② ikhetha iparameter ekalisiweyo yomfowunelwa
Misela iiparitha ezilinganisiweyo zoqhagamshelwano ngokwento ehlawulisiweyo kunye neeparitha zokusebenza, ezifana ne-voltage, yangoku, amandla, i-frequency, njl.
(1) I-coil voltage ye-contactor kufuneka ibe ngaphantsi ngokubanzi, ukwenzela ukuba iimfuno zokugquma kwe-contactor zincitshiswe, kwaye zikhuselekile xa zisetyenziswa.Xa isiphaluka solawulo silula kwaye ukusetyenziswa kwezixhobo zombane kuncinci, i-380V okanye i-220V yombane inokukhethwa ngokuthe ngqo.Ukuba isiphaluka sinzima.Xa inani lezixhobo zombane ezisetyenzisiweyo lidlula i-5, i-coil ye-36V okanye i-110V yombane ingasetyenziselwa ukuqinisekisa ukhuseleko.Kodwa ukuze kuququzelelwe kwaye kuncitshiswe izixhobo, rhoqo ngokokhetho lwamandla ombane wegridi.
(2) I-frequency yokusebenza kwe-motor ayikho phezulu, njenge-compressor, impompo yamanzi, i-fan, i-air conditioning, njl.
(3) Kwimoto yohlobo lomsebenzi onzima, njengemoto ephambili yezixhobo zoomatshini, izixhobo zokuphakamisa, njl.
(4) Ngenjongo ekhethekileyo yeenjini.Xa ihlala isebenza kwimeko yokuqala kunye nokubuyisela umva, umnxibelelanisi unokukhethwa ngokufanelekileyo ngokuhambelana nobomi bombane kunye nokuqala kwangoku, okukhethiweyo CJ10Z, CJ12,
(5) Xa ulawula i-transformer kunye ne-contactor, umbane wokunyuka kufuneka uqwalaselwe.Ngokomzekelo, umatshini we-welding wombane unokukhetha ngokubanzi abafowunelwa ngamaxesha angama-2 omlinganiselo olinganisiweyo we-transformer, njenge-CJT1, CJ20, njl.
(6) Umbane olinganisiweyo we-contactor ubhekisela kumandla aphezulu avumelekileyo oqhagamshelwano phantsi komsebenzi wexesha elide, kunye nobude be-8H, kwaye ifakwe kwibhodi yokulawula evulekileyo.Ukuba imeko yokupholisa ihlwempuzekileyo, umbane olinganisiweyo we-contactor ukhethwa ngamaxesha angama-1.1-1.2 omthamo olinganisiweyo womthwalo xa ukhethiwe.
(7) Khetha inombolo kunye nodidi lwabafowunelwa.Inombolo kunye nohlobo lwabafowunelwa luya kuhlangabezana neemfuno zesiphaluka solawulo.
