Isicelo seMagnetic ac contactor

Okokuqala, iimpawu ezintathu eziphambili ze-AC contactor:
1. Ikhoyili ye-AC yoqhagamshelwano.Ii-Ccoils zivame ukuchongwa ngu-A1 kunye ne-A2, kwaye zinokwahlulwa ngokulula zibe ngabafowunelwa be-AC kunye nabafowunelwa be-DC.Sihlala sisebenzisa abafowunelwa be-AC, apho i-220 / 380V isetyenziswa kakhulu:
2. UMfowunelwa we-AC Uqhagamshelwano oluphambili.I-L1-L2-L3 ixhunywe kumgca wokungena kwamandla wesigaba sesithathu, kwaye i-T1 T2-T3 ixhunyiwe kumgca wokuphuma kwamandla, kwaye ingasetyenziselwa ukudibanisa kumgca womthwalo.Abafowunelwa abaphambili be-AC abafowunelwa bahlala bevula abafowunelwa, ikakhulu beqhagamshelwe kwisekethe ephambili, ukulawula ukuqala kunye nokumiswa kwemoto kunye nezinye izixhobo!
3. Abafowunelwa abancedisayo be-AC contactor.Abancedisi abafowunelwa banokwahlulwa babe kwindawo evulekileyo rhoqo HAYI kunye nendawo eqhelekileyo yokuvala i-NC.
I-3-1 Ngokuqhelekileyo indawo evulekileyo HAYI, ngokuqhelekileyo ivulekileyo inqaku elithi NO lisetyenziselwa ukudibanisa nokulawula ukuzitshixa kunye nokuhanjiswa kwesignali yokusebenza, njengale: I-AC contactor ihlala ivula iphoyinti NO kwisalathisi esibomvu sokukhanya sinokusetyenziswa njengomsebenzi wemoto. ukukhanya kwesalathisi, xa umbane we-AC contactor, uhlala uvula i-NO evaliweyo, vula ukukhanya kwesalathisi, ukuhambisa isignali yokusebenza kwemoto okanye yesiphaluka.
3-2.Indawo eqhelekileyo evaliweyo ye-NC ye-AC yoqhagamshelwano.Ngokubanzi, i-NC isetyenziselwa ikakhulu ukunxibelelana kweesekethe 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, esinokusetyenziswa njengesalathisi sokumisa isiphaluka okanye i-motor.Xa i-AC contactor inikwe 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:
Okokuqala, amacandelo aphambili e-AC contactor: ikhoyili, intsimbi engundoqo, intwasahlobo yokusetha ngokutsha, inkqubo yoqhagamshelwano kunye nezixhobo zezixhobo kunye nezinye izinto.
1. Qonda ngokulula i-armature ye-AC contactor.I-armature idibanisa inkqubo yoqhagamshelwano, xa i-armature ihamba phezulu kwaye ihla, indawo yoqhagamshelwano iya kutshintsha ngokufanelekileyo, njengale: ngokuqhelekileyo ivula inqaku NO ivaliwe, isoloko ivaliwe i-NC inqanyuliwe kunye nokunye, oku kusetyenziso olusisiseko!
2. Amanye amacandelo abalulekileyo: i-core, iikhoyili kunye nokusetha kwakhona imithombo!Ingcaciso emfutshane yolu lwazi yile:
Nantsi indlela abafowunelwa be-AC abasebenza ngolona lwimi lufikelelekayo:
Ngaphambi kokuba i-AC contactor ingasebenzi: i-coil ayikwazi ukuba ngumbane, ingundoqo ayinayo i-electromagnetic suction, i-armature ayiyi kuhamba, i-spring elasticity ihlala iqhelekileyo, ngeli xesha indawo evulekileyo ehlala ivuliwe NO ivaliwe, indawo ehlala ivaliwe i-NC. kwi, le yimeko eqhelekileyo.
Umnxibelelanisi we-AC wombane: umbane wekhoyili, undoqo wentsimbi uvelisa ukufunxa kwe-electromagnetic, unokoyisa ukusetwa kwakhona kwe-elasticity yasentwasahlobo, tsala intwana ishukunyiswe ezantsi, eli xesha inkqubo yoqhagamshelwano iya kutshintsha: ngokufuthi ivula inqaku HAYI ivaliwe, ivalwa rhoqo inqaku le-NC liyacinywa, le yeyona nto isisiseko. ulawulo contactor, contactor ngoqhagamshelwano on-off utshintsho ukulawula ngokungathanga ngqo isekethe!
