Iimpawu ezintathu eziphambili ze-AC contactor

Okokuqala, iimpawu ezintathu eziphambili ze-AC contactor:

1. I-AC contactor coil.Cils zivame ukuchongwa yi-A1 kunye ne-A2 kwaye inokwahlulwa ngokulula ibe yi-AC contactors kunye ne-DC contactors.Sihlala sisebenzisa abafowunelwa be-AC, apho i-220 / 380V isetyenziswa kakhulu:

2. Indawo yoqhagamshelwano ephambili ye-AC contactor.L1-L2-L3 ixhunywe kumgca wokungena kwamandla wesigaba sesithathu, kwaye i-T1 T2-T3 ixhunyiwe kumgca wokuphuma kwamandla, kwaye ingasetyenziselwa ukudibanisa umgca womthwalo. abafowunelwa abaphambili be-AC abafowunelwa bahlala bevula abafowunelwa, ikakhulu beqhagamshelwe kwisekethe ephambili, ukulawula ukuqala kunye nokumiswa kwemoto kunye nezinye izixhobo!

3. Abancedisi abancedisayo be-AC contactor.Abafowunelwa abancedisayo banokwahlulwa ibe yindawo evulekileyo rhoqo NO kunye neendawo ezivaliweyo NC.

I-3-1 ihlala ivulekile inqaku HAYI, idla ngokuvula inqaku elithi NO lisetyenziswa ikakhulu kwi-contactor self-locking control kunye nesignali yokusebenza yokudlulisa ukuze isetyenziswe, njengale: Uqhagamshelwano lwe-AC luhlala luvula inqaku HAYI kwisikhanyiso esibomvu sinokusebenza njengesalathisi sokusebenza kwemoto. ukukhanya, xa i-AC i-contactor inombane, ihlala ivula i-NO ivaliwe, vula ukukhanya kwesalathisi, ukuhambisa isignali yokusebenza kwemoto okanye yesiphaluka.

I-3-2, Indawo eqhelekileyo yokuvala i-NC ye-AC contactor. Ngokubanzi, i-NC isetyenziselwa ukudibanisa kunye nokuhanjiswa komqondiso.

Ngokomzekelo, i-motor positive kunye ne-reverse control circuit isebenzisa umsebenzi odibeneyo we-contactor rhoqo ivaliwe indawo ye-NC.

Ngokomzekelo, i-AC contactor rhoqo i-NC yokuvala i-NC idibaniswe nokukhanya kwesalathisi esiluhlaza, esinokusebenza njengesalathisi sokumisa isiphaluka okanye i-motor.Xa umnxibelelwano we-AC unikwe amandla, indawo yokuvala rhoqo i-NC inqanyuliwe, ukukhanya kwesalathisi sokumisa kuvaliwe, ukukhanya kwesalathisi sokusebenza okuhambelanayo kukhanya, kwaye isiphaluka siqhuba.

Okwesibini, ndiyaqonda iimpawu ezintathu zangaphandle ze-AC zoqhagamshelwano, kwaye emva koko jonga ngokulula ngaphakathi kwe-AC contactor:

1. Amacandelo aphambili e-AC contactor: i-coil, i-iron core, i-reset spring, inkqubo yoqhagamshelwano kunye ne-armature kunye namanye amacandelo.

1. Ukuqonda ngokulula i-armature ye-AC contactor.I-Armature idibanisa inkqubo yoqhagamshelwano, xa i-armature ihamba phezulu kwaye ihla, umfowunelwa uya kutshintsha ngokufanelekileyo, njengale: ngokuphindaphindiweyo inqaku elivulekileyo NO livaliweyo, lihlala livaliwe i-NC inqanyuliwe njalo njalo, oku. lusetyenziso olusisiseko!

2. Amanye amacandelo abalulekileyo: undoqo, ikhoyili, kunye nokuseta ngokutsha imithombo!Ingcaciso emfutshane yeli nqaku yile:

Nantsi indlela abafowunelwa be-AC abasebenza ngolona lwimi lufikelelekayo:

Ngaphambi kokuba i-AC contactor ingabi nombane: i-coil ayikwazi ukuba ngumbane, i-core ayinayo i-electromagnetic suction, i-armature ayiyi kuhamba, i-spring elasticity ihlala iqhelekileyo, ngeli xesha lihlala livulekile inqaku elithi NO licinyiwe, lihlala livaliwe i-NC. le yimeko eqhelekileyo.

Umnxibelelanisi wombane we-AC: icoil yombane, intsimbi engundoqo yokufunxa i-electromagnetic, inokoyisa ukuseta kwakhona ukuqina kwentwasahlobo, ukutsala kancinci ukuya ezantsi, ngeli xesha, inkqubo yoqhagamshelwano iya kutshintsha: ihlala ivula inqaku HAYI ivaliwe, ihlala ivaliwe indawo ye-NC, le yeyona nto ibalulekileyo. ulawulo olusisiseko contactor, contactor ngotshintsho loqhagamshelwano ukulawula ngokungathanga ngqo isekethe!

Emva kokuba umnxibelelanisi we-AC ulahlekelwe amandla okanye ukucima amandla, ikhoyili ayiyi kuba ngumbane, ingundoqo ayinayo i-electromagnetic suction, ngeli xesha, ukuqina kwe-reset spring kuqhuba ukusetha kwakhona kwe-armature, i-armature bounce, ngeli xesha, i-armature drives. inkqubo yoqhagamshelwano ye-AC yoqhagamshelwano ukuhamba, ukubuyisela kwimeko yokuqala: indawo ehlala ivulekile HAYI inqanyuliwe, indawo ehlala ivaliwe i-NC ivaliwe.
