I-Contactor sisixhobo sokutshintsha okuzenzekelayo esisetyenziselwa ukutshintsha rhoqo okanye ukucima iisekethe eziphezulu zangoku ezifana ne-AC kunye neesekethe eziphambili ze-DC kunye neesekethe zokulawula umthamo omkhulu.Ngokomsebenzi, ukongeza kukutshintsha okuzenzekelayo, umnxibelelanisi naye unomsebenzi wokusebenza okude kunye nokulahleka kombane (okanye i-undervoltage) umsebenzi wokhuselo ongenawo umatshini wezandla, kodwa akanalo umthwalo ogqithisileyo kunye nemisebenzi yokhuseleko yesekethe emfutshane. i-low-voltage circuit breaker.
Izinto eziluncedo kunye nokuhlelwa kwabafowunelwa
I-contactor ineenzuzo ze-frequency yokusebenza ephezulu, ubomi benkonzo ende, umsebenzi othembekileyo, ukusebenza okuzinzileyo, ixabiso eliphantsi, kunye nokugcinwa lula.Isetyenziselwa kakhulu ukulawula iimoto, izixhobo zokufudumeza zombane, oomatshini bombane welding, iibhanki capacitor, njl.
Ngokwefom yesekethe yoqhagamshelwano oluphambili, yahlulwe ibe yi: DC contactor kunye ne-AC contactor.
Ngokwendlela yokusebenza, yahlulwe yaba: i-electromagnetic contactor kunye ne-magnetic contactor esisigxina.
Ubume kunye nomgaqo wokusebenza wombane ophantsi we-AC contactor
Ulwakhiwo: Umnxibelelanisi we-AC ubandakanya indlela ye-electromagnetic (coil, intsimbi engundoqo kunye ne-armature), uqhagamshelwano oluphambili kunye nenkqubo yokucima i-arc, uqhagamshelwano oluncedisayo kunye nentwasahlobo.Abafowunelwa abaphambili bahlulahlulwe kuqhagamshelwano lwebhulorho kunye noqhagamshelwano lweminwe ngokomthamo wabo.Abafowunelwa be-AC abanomsinga ongaphezulu kwe-20A baxhotyiswe ngezixhobo zokucima i-arc, kwaye ezinye zineepleyiti zegridi okanye izixhobo zokucima i-arc ezivuthela imagnethi;abafowunelwa abancedisayo Amanqaku ahlulwe abe ngokuqhelekileyo avulekileyo (ohamba ngokusondeleyo) abafowunelwa kwaye ngokuqhelekileyo avaliwe (ohamba evulekile) abafowunelwa, bonke aba luhlobo lwebhulorho-uhlobo lwezakhiwo zokuqhawula kabini.Uqhagamshelwano oluncedisayo lunomthamo omncinci kwaye lusetyenziselwa ukudibanisa kwisiphaluka solawulo, kwaye akukho sixhobo sokucima i-arc, ngoko asikwazi ukusetyenziselwa ukutshintsha isiphaluka esiphambili.Ulwakhiwo luboniswe kumzobo ongezantsi:
Umgaqo: Emva kokuba i-coil ye-electromagnetic mechanism inikwe amandla, i-magnetic flux yenziwa kumbindi wentsimbi, kwaye umtsalane we-electromagnetic uveliswa kwisithuba somoya we-armature, esenza ukuba i-armature ivale.Uqhagamshelwano oluphambili luphinde luvalwe phantsi kwe-drive ye-armature, ngoko ke isiphaluka sixhunyiwe.Ngexesha elifanayo, i-armature iphinda iqhube oonxibelelwano abancedisayo ukuvala abafowunelwa abaqhelekileyo abavulekileyo kwaye bavule abafowunelwa abaqhelekileyo abavaliweyo.Xa i-coil i-de-energized okanye i-voltage iyancipha kakhulu, amandla okufunxa ayanyamalala okanye ayancipha, i-armature ivula phantsi kwesenzo sokukhululwa kwentwasahlobo, kwaye oonxibelelwano abaphambili kunye nabancedisayo babuyela kwimeko yabo yangaphambili.Iisimboli zecandelo ngalinye le-AC contactor zibonisiwe kulo mfanekiso ungezantsi:
Iimodeli kunye nezalathi zobugcisa ze-low-voltage AC contactors
1. Imodeli ye-AC ye-contactor ye-low-voltage
Abafowunelwa be-AC abaqhelekileyo abaveliswa kwilizwe lam yi-CJ0, CJ1, CJ10, CJ12, CJ20 kunye nolunye uluhlu lweemveliso.Kuluhlu lweemveliso ze-CJ10 kunye ne-CJ12, zonke iindawo ezichaphazelekayo zithatha isixhobo se-buffer, esinciphisa ngokufanelekileyo umgama woqhagamshelwano kunye ne-stroke.Inkqubo yokunyakaza inokwakheka okunengqiqo, i-compact structure, kunye ne-structural connection ngaphandle kwe-screws, ekulungele ukugcinwa.I-CJ30 ingasetyenziselwa uqhagamshelo olukude kunye nokwaphulwa kweesekethe, kwaye ilungele ukuqala nokulawula iinjini ze-AC rhoqo.
2. Iimpawu zobuchwephesha ze-low-voltage AC contactors
⑴I-voltage elinganisiweyo: ibhekiselele kumbane olinganisiweyo kuqhagamshelwano oluphambili.Amabanga adla ngokusetyenziswa ngala: 220V, 380 V, kunye ne-500 V.
⑵Ireyithiwe yangoku: ibhekisa kumsinga okaliwe womnxeba oyintloko.Amabanga asetyenziswa ngokuqhelekileyo ngala: 5A, 10A, 20A, 40A, 60A, 100A, 150A, 250A, 400A, 600A.
⑶Amabanga aqhelekileyo asetyenziswayo ombane olinganisiweyo wekhoyili ngala: 36V, 127V, 220V, 380V.
⑷ Ireyithingi yokusebenza rhoqo: ibhekisa kwinani loqhagamshelo ngeyure.
Umgaqo-siseko wokhetho lombane ophantsi we-AC contactor
1. Khetha uhlobo loqhagamshelwano ngokohlobo lomthwalo wangoku kwisekethe;
2. I-voltage elinganisiweyo ye-contactor kufuneka ibe mkhulu okanye ilingane ne-voltage elinganisiweyo yomjikelezo womthwalo;
3. I-voltage elinganisiweyo yekhoyili ekhangayo kufuneka ihambelane ne-voltage elinganisiweyo yesekethe yokulawula edibeneyo;
4. Umsinga olinganisiweyo kufuneka ube mkhulu okanye ulingane nomsinga olinganisiweyo wesekethe eyintloko elawulwayo.
