Umgaqo-siseko we-contactor

I-Contactor iphantsi kwesignali yegalelo yangaphandle inokuvula okanye icime ngokuzenzekelayo isekethe engundoqo kunye nomthwalo wezixhobo zokulawula ngokuzenzekelayo, ukongeza kwi-motor yokulawula, ingasetyenziselwa ukulawula ukukhanya, ukufudumeza, i-welder, umthwalo we-capacitor, ilungele ukusebenza rhoqo, i-remote control enamandla. isekethe yangoku, kwaye inomsebenzi othembekileyo, ubomi obude, ubungakanani obuncinci, ukukhutshwa koxinzelelo oluphantsi lomsebenzi wokukhusela, yenye yezona zinto zibaluleke kakhulu kwaye zisetyenziswa ngokuqhelekileyo kwinkqubo yokulawula i-relay-contactor.

I-contactor ebuyela umva luhlobo olusetyenziselwa ukulawula amandla aphezulu e-motor elungileyo kunye ne-reverse mechanical reversible ac contactor, iqulethe ii-contactor ezisemgangathweni ezimbini kunye neyunithi yokudibanisa ngoomatshini, igxininise inzuzo ye-ac contactor kunye ne-reverse switch, ukusebenza okulula, okukhuselekileyo nokuthembekileyo, ixabiso eliphantsi. , ubukhulu becala isetyenziselwa ukusebenza kakuhle kwemoto kunye nokubuyela umva, ukunyathela umva, ukusebenza rhoqo kunye nokusebenza kwendawo.

Abafowunelwa banokuvula kwaye baqhawule umbane wangoku, kodwa abanako ukunqumla i-short-circuit current, ngoko ke bahlala besetyenziselwa iifuse kunye ne-thermal relays.

hlela

Kukho iintlobo ezininzi zoqhagamshelwano, kwaye kukho iindlela ezine zokuhlela ngokubanzi, kubandakanywa neyokuqala.

① yahlulwe yaba yi-AC yoqhagamshelwano kunye ne-DC yoqhagamshelwano ngokohlobo lwangoku lwesekethe edityaniswe ngumfowunelwa oyintloko.

② ihlulwe ibe yi-monopole, i-bipolar, i-3,4, kunye neepali ze-5 ngokwenani leepali zoqhagamshelwano oluphambili.

③ yahlulwe ngohlobo oluqhelekileyo oluvulekileyo kunye nohlobo oluvaliweyo ngokweyona khoyili yoqhagamshelwano oluphambili.

④ yahlulwe ibe akukho sixhobo sokucima i-arc kwaye akukho sixhobo sokucima i-arc ngokwendlela yokucima i-arc.

Umgaqo wesakhiwo

Amacandelo aphambili onxibelelwano ngala;Inkqubo ye-electromagnetic, uqhagamshelwano, inkqubo yokucima i-arc, abafowunelwa abancedisayo, isibiyeli kunye nendlu, njl. inkqubo yokwahlula kwaye ivale umsebenzi, ukuze udibanise okanye ukhuphe i-loop.Xa iqhosha likhutshiwe, inkqubo ichasene nale ngasentla.

Iiparamitha eziphambili zobugcisa

① amandla ombane okusebenza alinganisiweyo: gabalala ibhekisa kumbane olinganisiweyo woqhagamshelwano oluphambili, kubandakanywa i-AC: 380V, 660V, 1140V, DC: 220V, 440V, 660V, njl.

② Ireyithingi yokusebenza ngoku: ngokubanzi ibhekisa kumhla olinganisiweyo woqhagamshelwano oluphambili, kuquka i-6A, 9A, 12A, 16A, 25A, 40A, 100A, 160A, 250A, 400A, 600A, 1000A, njl.

③ Ukuvula kunye nokuqhawula amandla: kubhekiselele kwixabiso langoku ukuba umnxibelelwano unokuvula kwaye aphule isixhobo sokufumana umbane.

④ ukufudumala kwangoku okuvunyelweneyo: ekuvavanyeni phantsi kweemeko ezikhankanyiweyo, ukusebenza ngoku kwi-8h, kwaye ubuninzi bangoku buqhutywe xa ukunyuka kweqondo lokushisa kwenxalenye nganye kungadluli kwixabiso lomda.

⑤ ukusebenza rhoqo: kubhekisa kwinani lemisebenzi evunyelweyo ngeyure.

⑥ Ubomi boomatshini kunye nobomi bombane: ibhekisa kumndilili wenani lemisebenzi phambi kokusilela komatshini kwepali engundoqo ngaphandle komthwalo.Ubomi bomatshini bunxulumene nokusebenza rhoqo. Ubomi bombane bunxulumene nodidi losetyenziso, umlinganiselo wokusebenza ngoku, kunye nomlinganiselo wokusebenza kwamandla ombane.
