Umnxibelelanisi we-AC (Olunye uQhagamshelwano lwangoku), lilonke, Uphuculo oluqhubekayo kwimilo kunye nokusebenza, Kodwa ngokusebenza okufanayo, Ikakhulu iqulunqwe yinkqubo ye-electromagnetic, inkqubo yoqhagamshelwano, isixhobo sokucima i-arc kunye nezinto ezincedisayo, Inkqubo ye-electromagnetic iqulunqwe ikakhulu ngecoil. , intsimbi yentsimbi (isiseko sentsimbi) kunye ne-armature (intsimbi ehambayo) iinxalenye ezintathu;Inkqubo yoqhagamshelwano yahlulwe yaba yi-point contact, uqhagamshelwano lomgca kunye noqhagamshelwano lomphezulu wesithathu;Isixhobo sokucima i-arc sihlala sithatha ukucima i-arc yombane ephindwe kabini, i-longitudinal joint arc yokucima kunye nesango lokucima iindlela ezintathu zokucima i-arc, Ukuphelisa i-arc yombane eyenziwa ngabafowunelwa abaguquguqukayo kunye ne-static ngexesha lokwahlula kunye nokuvala inkqubo, abafowunelwa abanomthamo ongentla. 10A banezixhobo zokucima i-arc;Amacandelo ancedisayo ikakhulu abandakanya intwasahlobo yokusabela, i-buffer spring, intwasahlobo yoxinzelelo loqhagamshelwano, indlela yokuhambisa, isiseko kunye nekholamu yesiphelo njalo njalo.
Umgaqo osebenzayo we-AC contactor kukuba xa i-coil ye-contactor inamandla, i-coil yangoku iya kuvelisa intsimi yamagnetic, kwaye intsimi yemagnethi eyenziwe yenza ukuba i-static core ivelise ukufunxa kwe-electromagnetic ukutsala i-core, kwaye iqhube i-AC contact point action. Uqhagamshelwano oluhlala luvaliwe luvaliwe, luhlala luvaliwe uqhagamshelwano oluvaliweyo, ezi zimbini zidibanisa. , kwaye uqhagamshelwano oluhlala luvaliwe luyavala.Kukusebenzisa amandla e-electromagnetic kunye ne-spring elasticity ukusebenzisana, ukufezekisa uqhagamshelwano loqhagamshelwano kunye nokwahlula.
Ngokweemfuno zabathengi, ukuveliswa kweekhabhinethi zokulawula abathengi, kungakhathaliseki ukuba kukhetho loqhagamshelwano lonxibelelwano okanye amanye amacandelo, baya kuzama konke okusemandleni abo ukuba abathengi bakhethe kwaye bahlangabezane neemfuno zamacandelo aphezulu asekhaya nangaphandle.
Umthetho-siseko wokukhetha we-AC contactor:
(1) Umgangatho wombane kufuneka ufane nomthwalo, kwaye uhlobo lwe-contactor kufuneka lufaneleke kumthwalo.
(2) Umsinga obaliweyo womthwalo uya kuhambelana nenqanaba lomthamo we-contactor, oko kukuthi, umsinga obalwayo ungaphantsi okanye ulingana nomgangatho osebenzayo we-contactor. yangoku yomthwalo, kwaye ukuphuka kwangoku kukhulu kunokusebenza komthwalo.Umbane obalwayo womthwalo kufuneka uqwalasele indawo yokusebenza yangempela.Ngomthwalo kunye nexesha elide lokuqala, isantya esiphezulu sesiqingatha seyure asikwazi ukudlula ukufudumala kwangoku okuvunyelweneyo.
(3) Khangela i-short-time-dynamic and thermal stability.Isigaba sesithathu sombane wesiphaluka esifutshane somgca asiyi kudlula amandla avumelekileyo kunye ne-thermal stable current of the contactor.Xa umbane wesiphaluka omfutshane unqanyulwe ngu-contactor, amandla okuphuka kwe-contactor nawo aya kuqinisekiswa.
(4) I-voltage elinganisiweyo, yangoku, ubuninzi kunye namandla akhoyo oqhagamshelwano oluncedisayo lwekhoyili yokufunxa ye-contactor iya kuhlangabezana neemfuno zocingo zesekethe yokulawula. ixabiso le-voltage yokusebenza, i-contactor kufuneka isebenze kwi-85 ~ 110% yexabiso le-voltage elinganisiweyo.Ukuba umgca ude kakhulu, i-coil ye-contactor ayinakubonakalisa umyalelo wokuvala ngenxa yokuhla kwamandla aphezulu;umyalelo wohambo awunakusebenza kunye ne-high line capacitor.
(5) Khangela i-frequency yokusebenza evumelekileyo yoqhagamshelwano ngokuhambelana namaxesha okusebenza.Ukuba i-frequency yokusebenza idlula ixabiso elichaziweyo, i-current rated current kufuneka iphindwe kabini.
(6) I-short-circuit protection element parameters kufuneka ikhethwe kunye ne-contactor parameters.Nceda ubhekisele kwincwadana yesampula, enika ngokubanzi itafile ehambelanayo yoqhagamshelwano kunye ne-fuses.
