Yeyiphi imisebenzi yabafowunelwa be-AC?

AC isiqhagamshelanisi umsebenzi intshayelelo:

IUmnxibelelanisi we-ACyinto yolawulo oluphakathi, kwaye inzuzo yayo kukuba iyakwazi ukuvula kwaye ivale umgca rhoqo, kwaye ilawule umsinga omkhulu kunye nomsinga omncinci. Ukusebenza kunye ne-thermal relay kunokudlala indima ethile yokukhusela umthwalo ogqithisiweyo kwisixhobo somthwalo. Kuba isebenza kwaye icinyiwe ngokufunxa intsimi ye-electromagnetic, isebenza ngakumbi kwaye ibhetyebhetye ngakumbi kunesekhethi zokuvula kunye nokuvala ngesandla. Iyakwazi ukuvula nokuvala imigca yomthwalo emininzi ngexesha elinye. Kananjalo inomsebenzi wokuzitshixa. Emva kokuba i-suction ivaliwe, inokungena kwi-self-locking state kwaye iqhubeke nokusebenza. Abafowunelwa be-AC basetyenziswa ngokubanzi njengokuqhawula amandla kunye neesekethe zokulawula.

Umnxibelelanisi we-AC usebenzisa umfowunelwa oyintloko ukuvula nokuvala isiphaluka, kwaye usebenzisa uqhagamshelwano oluncedisayo ukwenza umyalelo wokulawula. Abafowunelwa abaphambili ngokubanzi bavuleleke kuphela abafowunelwa, ngelixa abafowunelwa abancedisayo bahlala benezibini ezimbini zoqhagamshelwano ezinemisebenzi eqhele ukuvuleka neqhele ukuvaleka. Abafowunelwa abancinci nabo bahlala besetyenziselwa ukuhanjiswa okuphakathi ngokubambisana nesekethe ephambili. Abafowunelwa be-AC contactor benziwe nge-alloy yesilivere-tungsten, ene-conductivity elungileyo yombane kunye nokumelana nokushisa okuphezulu. Amandla esenzo seUmnxibelelanisi we-ACivela kwi-electromagnetic ye-AC. I-electromagnetic yenziwe ngamacwecwe amabini ensimbi "yentaba" amile okwe-silicon, enye yazo ilungisiwe, kwaye i-coil ibekwe kuyo. Kukho iindlela ezahlukeneyo zombane onokukhetha kuzo. Ukuze uzinzise amandla amagnetic, i-short-circuit ring yongezwa kwi-suction surface ye-iron core. Emva kokuba i-AC contactor ilahlekelwe amandla, ixhomekeke entwasahlobo ukuba ibuyele.

Esinye isiqingatha sisisiseko sentsimbi esishukumayo, esinesakhiwo esifanayo nesigxina sentsimbi esisigxina, kwaye sisetyenziselwa ukuqhuba ukuvulwa kunye nokuvalwa koqhagamshelwano oluphambili kunye noqhagamshelwano oluncedisayo. Umnxibelelanisi ongaphezulu kwama-amps angama-20 uxhotyiswe nge-arc yokucima i-arc, esebenzisa amandla e-electromagnetic eyenziwa xa isiphaluka sinqanyuliwe ukukhupha ngokukhawuleza i-arc ukukhusela abafowunelwa. IUmnxibelelanisi we-ACyenziwe iyonke, kwaye imilo kunye nokusebenza ziphucula rhoqo, kodwa umsebenzi uhlala ufana. Kungakhathaliseki ukuba iteknoloji ihamba phambili kangakanani, i-AC contactor eqhelekileyo isenayo indawo yayo ebalulekileyo.
