1. Xa ukhetha iumnxibelelanisi, ezi zinto zilandelayo ziqwalaselwe nzulu.
①Isinxibelelanisi se-AC sisetyenziselwa ukusebenzisa umthwalo we-AC, kwaye i-DC contactor isetyenziselwa umthwalo we-DC.
②Umjelo osebenzayo ozinzileyo weyona ndawo iphambili yoqhagamshelwano kufuneka ibe mkhulu okanye ilingane nomjiko wesiphaluka samandla omthwalo.Kufuneka kwakhona kuqatshelwe ukuba ukusebenza ngokuzinzile kwendawo yoqhagamshelwano ephambili ye-contactor ibhekisela kumbane onokusebenza ngokuqhelekileyo phantsi kweemeko ezichaziweyo (i-voltage kumsebenzi wexabiso elilinganisiweyo, uhlobo lwesicelo, amaxesha okusebenza kwangempela, njl.).Xa imigangatho yesicelo esithile yahlukile, yangoku nayo iya kutshintsha.
③ I-voltage ngexesha lokusebenza okuzinzile kwe-breaker sekethe engundoqo kufuneka ibe mkhulu okanye ilingane nombane wesiphaluka samandla omthwalo.
④ Umbane olinganisiweyo wekhoyili ye-electromagnetic kufuneka ihambelane nolawulo lombane lwelophu.
2. Amanyathelo okusebenza okukhethwa komnxibelelanisi.
①Uhlobo loqhagamshelwano kufuneka lukhethwe ngokohlobo lomthwalo.
②Khetha iiparamitha eziphambili zexabiso elilinganisiweyo loqhagamshelwano.
Misela iiparitha eziphambili zexabiso elilinganisiweyo le-contactor, njenge-voltage, yangoku, amandla aphumayo, i-frequency, njl.
1Xa i-loop yokulawula ilula kwaye kukho izixhobo ezimbalwa zendlu, i-voltage ye-380V okanye i-220V inokukhethwa ngokukhawuleza.Ukuba isiphaluka samandla sinzima kakhulu.Xa inani elipheleleyo lezixhobo zendlu ezisetyenzisiweyo lidlula i-5, 36V okanye i-110V i-voltage solenoid coils ingakhethwa ukuqinisekisa ukhuseleko.Nangona kunjalo, ukwenzela ukuba kube lula ukuququzelela kunye nokunciphisa oomatshini kunye nezixhobo, ukhetho luhlala luqhutywa ngokuhambelana nombane wegridi yamandla athile.
(2) I-frequency yokusebenza ye-motor ayikho phezulu, njenge-compressors yefriji, iimpompo ze-centrifugal, iifeni ze-centrifugal, i-air conditioners ephakathi, njl.
(3) Kwiimotor ze-counterweight zemihla ngemihla, ezifana ne-motor enkulu ye-CNC lathes, iiplatifomu zokunyusa, njl.
(4) IiMotor ngeenjongo ezingundoqo ezizodwa.Ngokuqhelekileyo xa umsebenzi uphendulwe, umnxibelelanisi unokukhethwa ngokuhambelana nobomi benkonzo yesixhobo sombane kunye nesixa sokusebenza ngoku, CJ10Z.CJ12.
(5) Xa usebenzisa i-contactor ukulawula i-transformer, ubukhulu bombane wokunyuka kufuneka buthathelwe ingqalelo.Ngokomzekelo, oomatshini be-welding ye-DC banokudla ngokukhetha abafowunelwa ngokusekwe ngokuphindwe kabini umlinganiselo wangoku we-transformer, njenge-CJT1.CJ20 njalo njalo.
(6) Umlinganiselo olinganisiweyo we-contactor ubhekisela kumandla aphezulu avumelekileyo kwi-contactor ngexesha lokusebenza kwexesha elide, ixesha lokulibaziseka lingaphantsi okanye lilingana ne-8h, kwaye lifakwe kumlawuli ovulekileyo.Ukuba imeko yokupholisa ihlwempuzekileyo, umbane olinganisiweyo we-contactor kufuneka ukhethwe ngokwe-1.1-1.2 amaxesha angoku okulinganisa umthwalo.
(7) Khetha isixa esipheleleyo kunye nodidi lwabafowunelwa.Isixa esipheleleyo kunye nohlobo lwabafowunelwa kufuneka bahlangabezane nemimiselo yesiphaluka solawulo.
