AC contactor IEC umgangatho

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 isicelo kumandla, ukuhanjiswa kunye nombane, ukuba sibhekisela kumbane wemizi-mveliso usebenzisa i-coil ngokusebenzisa langoku ukuvelisa intsimi magnetic, uqhagamshelwano luvaliwe, ukulawula umthwalo wezixhobo zombane, ngoko kunokuthiwa ukuba i-contactor yenziwe inkqubo ye-electromagnetic kunye nenkqubo yoqhagamshelwano.
1. 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:
I-GB / T 8871-2001 i-AC yoqhagamshelwano nesixhobo sokugcina amandla;
I-GB / T 14808-2016 i-high-voltage AC contactor, isilawuli esisekelwe kwi-contactor kunye ne-motor starter;
I-GB / T 17885-2016 I-Electromechanical contactors zendlu kunye neenjongo ezifanayo;
I-GB 21518-2008 i-AC yoqhagamshelwano lwe-AC yexabiso lomda wokuphumelela kwamandla kunye nebakala lokuchaneka kwamandla;
