Isimiso sesakhiwo se-contactor

I-Contactor ingaphansi kwesiginali yokufaka yangaphandle ingavula noma ivale ngokuzenzakalelayo isekethe eyinhloko ngomthwalo wemishini yokulawula othomathikhi, ngaphezu kokulawula injini, ingasetshenziswa futhi ukulawula ukukhanya, ukushisa, i-welder, umthwalo we-capacitor, ofanele ukusebenza njalo, isilawuli kude siqinile. isifunda samanje, futhi inomsebenzi onokwethenjelwa, impilo ende, usayizi omncane, ukukhululwa kwengcindezi ephansi yomsebenzi wokuvikela, ingenye yezingxenye ezibaluleke kakhulu nezisetshenziswa kakhulu ohlelweni lokulawula i-relay-contactor.

I-contactor ehlehliswayo iwuhlobo olusetshenziselwa ukulawula amandla aphezulu e-motor positive kanye ne-reverse mechanical reversible ac contactor, iqukethe othintana nabo ababili abajwayelekile kanye neyunithi yokukhiya yokukhiya, igxilise izinzuzo ze-ac contactor ne-reverse switch, ukusebenza okulula, okuphephile nokuthembekile, izindleko eziphansi. , ikakhulukazi esetshenziselwa ukusebenza kwemoto evumayo nokuhlehlayo, i-braking ehlehlayo, ukusebenza okungaguquki kanye nokusebenza kwendawo.

Othintana nabo bangavula futhi banqamule umthamo wamanje, kodwa abakwazi ukunqamula i-short-circuit current, ngakho-ke bavame ukusetshenziswa namafuse kanye nama-thermal relay.

hlukanisa

Kunezinhlobo eziningi zoxhumana nabo, futhi ngokuvamile kunezindlela ezine zokuhlukanisa, kuhlanganise neyokuqala.

① ihlukaniswe i-AC contactor kanye ne-DC contactor ngokohlobo lwamanje lwesekethe exhunywe othintana naye oyinhloko.

② ihlukaniswe yaba yi-monopole, i-bipolar, i-3,4, nezigxobo ezingu-5 ngokuya ngenani lezigxobo zoxhumana nabo abakhulu.

③ ihlukaniswe yaba uhlobo oluvamile oluvulekile futhi oluvamise ukuvaleka ngokuya ngekhoyili yokuxhumana evusa amadlingozi.

④ ihlukaniswe ingabi idivayisi yokucisha i-arc futhi ayikho idivayisi yokucisha i-arc ngokuya ngemodi yokucisha i-arc.

Isimiso sesakhiwo

Izingxenye eziyinhloko ze-contactor yilezi;isistimu ye-electromagnetic, ukuthintana, isistimu yokucisha i-arc, abathintwayo abasizayo, ubakaki nezindlu, njll.Lapho inkinobho icindezelwa, ikhoyili inikezwa amandla, umgogodla omile udonsa uzibuthe, futhi umgogodla onyakazayo uyamuncwa ukuze ushayele i-shaft ukwenza othintana naye. ukuhlukanisa uhlelo bese uvala ukusebenza, ukuze uxhume noma unqamule iluphu.Lapho inkinobho ikhishwa, inqubo iphambene nalokhu okungenhla.

Imingcele yezobuchwepheshe eyinhloko

① I-voltage elinganiselwe yokusebenza: ngokuvamile ibhekisela ku-voltage elinganiselwe yothintana naye oyinhloko, okuhlanganisa i-AC: 380V, 660V, 1140V, DC: 220V, 440V, 660V, njll.

② Isilinganiso sokusebenza samanje: ngokuvamile sibhekisela kumanje okulinganiselwe kothintana naye oyinhloko, okuhlanganisa 6A, 9A, 12A, 16A, 25A, 40A, 100A, 160A, 250A, 400A, 600A, 1000A, njll.

③ Ikhono lokuvula nokuphuka: libhekisela kunani lamanje othintana naye angalivula futhi aphule idivayisi eyamukelayo kagesi.

④ ukushisisa okuvunyelwene ngakho: ekuhlolweni ngaphansi kwezimo ezishiwo, okwamanje kusebenza ngo-8h, kanye nomthamo wamanje othwala lapho ukukhuphuka kwezinga lokushisa kwengxenye ngayinye kungadluli inani lomkhawulo.

⑤ imvamisa yokusebenza: ibhekisa enanini lemisebenzi evunyelwe ngehora.

⑥ Impilo yemishini nempilo kagesi: ibhekisela enanini eliyisilinganiso lemisebenzi ngaphambi kokuhluleka komshini kwepali eyinhloko ngaphandle komthwalo.Impilo yomshini ihlobene nemvamisa yokusebenza.Impilo kagesi iyinani elijwayelekile lokuthwala imisebenzi esigxotsheni esikhulu ngaphandle kokulungiswa. Impilo kagesi ihlobene nohlobo lokusetshenziswa, isilinganiso samanje sokusebenza, kanye ne-voltage yokusebenza elinganiselwe.
