Ukukhethwa koMfowunelwa we-AC weVoltage ephantsi kuYilo loMbane

I-low-voltage AC contactors zisetyenziselwa ukucima kunye nokucima umbane wezixhobo zombane, ezinokulawula izixhobo zombane ukusuka kumgama omde, kwaye ugweme ukwenzakala komntu xa uvula kunye nokucima umbane wesixhobo. Ukukhethwa kwe-AC contactor kubaluleke kakhulu ekusebenzeni okuqhelekileyo kwezixhobo zamandla kunye neentambo zombane.
1. Ubume kunye neeparamitha ze-AC contactor
Ukusetyenziswa ngokubanzi, i-AC ye-contactor device iyadingeka ukuba ibe nesakhiwo esincinci, kulula ukuyisebenzisa, isixhobo esihle sokuvuthela magnetic soqhagamshelwano oluhambayo kunye ne-static, isiphumo esihle sokucima i-arc, i-zero flashover, kunye nokunyuka kweqondo lokushisa elincinci. Ngokwendlela yokucima i-arc, yahlulwe ngohlobo lomoya kunye nohlobo lwe-vacuum, kwaye ngokwendlela yokusebenza, yahlulwe yaba luhlobo lwe-electromagnetic, uhlobo lwepneumatic kunye nohlobo lwe-electromagnetic pneumatic.
Iiparamitha ezilinganisiweyo zombane we-contactor zahlulwe kumbane ophezulu kunye nombane ophantsi, kwaye umbane ophantsi ngokubanzi ngu-380V, 500V, 660V, 1140V, njl.
Umsinga wombane wohlulwe ngokutshintshana ngoku kunye nokwangoku ngokuthe ngqo ngokohlobo. Iiparameters zangoku zibandakanya ukulinganisa ukusebenza kwangoku, ukufudumeza okuvunyelweneyo ngoku, ukwenza i-current and breaking current, ukufudumeza okuvunyelweneyo koqhagamshelwano oluncedisayo kunye nexesha elifutshane lokumelana nombane we-contactor, njl njl. imisinga esebenzayo ehambelana nobushushu obuvunyelweneyo. Ngokomzekelo, kwi-CJ20-63, umlinganiselo wokusebenza osebenzayo womnxeba oyintloko uhlukaniswe kwi-63A kunye ne-40A. I-63 kwi-parameter yemodeli ibhekisela kumbane wokufudumeza ovunyelweneyo, ohambelana nesakhiwo sokufakelwa kwegobolondo ye-contactor, kunye nokulinganisa okusebenzayo okwangoku kuhambelana nomthwalo okhethiweyo wangoku, ohambelana nomgangatho wombane.
Iikhoyili zoqhagamshelwano ze-AC zahlulwe zibe yi-36, 127, 220, 380V njalo njalo ngokombane. Inani leepali ze-contactor lihlulwe kwi-2, 3, 4, 5 izibonda kunye nokunye. Kukho izibini ezininzi zoqhagamshelwano oluncedisayo ngokwesiqhelo evulekileyo neqhele ukuvalwa, kwaye zikhethwa ngokweemfuno zolawulo.
Ezinye iiparameters ziquka uxhulumaniso, amaxesha okuphuka, ubomi bomatshini, ubomi bombane, ubuninzi obuvumelekileyo bokusebenza, ubuninzi obuvumelekileyo be-wiring ububanzi, imilinganiselo yangaphandle kunye nemilinganiselo yokufakela, njl njl.
Iintlobo zoQhagamshelwano eziqhelekileyo
Sebenzisa ikhowudi yodidi kumzekelo womthwalo oqhelekileyo wesixhobo esiqhelekileyo
