Izinto kunye nemigangatho yovavanyo loqhagamshelwano
kolu shicilelo lwenqaku ukukunika ukuba uhlele izinto zobhaqo zomfowunelwa kunye nemigangatho kunye neenkqubo ezithile ukuze ufunde, ngeenkcukacha, nceda ujonge ngezantsi:
Contactor, oko kwikhoyili ngokusebenzisa yangoku ukuvelisa intsimi magnetic, kwaye wenze uqhagamshelwano luvaliwe, ukuze ukulawula umthwalo izixhobo, contactor yahlulwe ac contactor (voltage AC) kunye DC contactor (voltage DC), oko isetyenziswe kumandla, ukuhanjiswa kunye nombane, ukuba sibhekisa kumbane wemizi-mveliso usebenzisa i-coil ngoku ukuvelisa intsimi yamagnetic, uqhagamshelwano oluvaliweyo, ukulawula umthwalo wezixhobo zombane, ngoko kunokuthiwa ukuba i-contactor iqulunqwe yinkqubo ye-electromagnetic. kunye nenkqubo yoqhagamshelwano.
Izinto zokuchongwa zabafowunelwa:
Amandla ombane, ukubonwa kwekhoyili, ixabiso lokumelana nobushushu obuphezulu, uvavanyo lokumelana nobushushu obuphantsi, amandla emagneti, uvavanyo lokuthembeka, uvavanyo lokuguga, uvavanyo lokumelana nemozulu, ukubonwa kobomi benkonzo, njl.
2. Iikhrayitheriya zovavanyo lokufunyanwa kwenxalenye yabafowunelwa:
