Kodi ntchito za AC contactors ndi chiyani?

Chiyambi cha ntchito ya AC contactor:

TheAC cholumikizirandi chinthu chowongolera chapakati, ndipo ubwino wake ndikuti amatha kuyatsa ndikuzimitsa mzere pafupipafupi, ndikuwongolera mphamvu yayikulu yokhala ndi kamphindi kakang'ono. Kugwira ntchito ndi relay yotenthetsera kuthanso kugwira ntchito yoteteza katundu wambiri pazida zonyamula. Chifukwa imagwira ntchito ndi kuyatsidwa ndi ma electromagnetic field suction, ndiyothandiza komanso yosinthika kuposa mabwalo otsegula ndi kutseka pamanja. Ikhoza kutsegula ndi kutseka mizere yolemetsa yambiri nthawi imodzi. Ilinso ndi ntchito yodzitsekera yokha. Pambuyo poyamwa kutsekedwa, ikhoza kulowa mudziko lodzitsekera ndikupitiriza kugwira ntchito. AC contactors chimagwiritsidwa ntchito ngati mphamvu kuswa ndi kulamulira madera.

The AC contactor ntchito kukhudzana waukulu kutsegula ndi kutseka dera, ndi ntchito kukhudzana wothandiza kuti apereke ulamuliro ulamuliro. Olumikizana nawo nthawi zambiri amakhala otseguka, pomwe othandizira amakhala ndi mapeyala awiri olumikizana omwe amakhala otseguka komanso otsekedwa. Ma contactors ang'onoang'ono amagwiritsidwanso ntchito ngati ma relay apakatikati molumikizana ndi dera lalikulu. The kulankhula kwa AC contactor anapangidwa ndi aloyi silver-tungsten, amene ali madutsidwe wabwino magetsi ndi kukana kutentha ablation. Mphamvu yochitapo kanthuAC cholumikiziraamachokera ku AC electromagnet. Maginito amagetsi amapangidwa ndi mapepala achitsulo a "mapiri" aang'ono a silicon, omwe amakhazikika, ndikuyikapo koyilo. Pali ma voltages osiyanasiyana ogwira ntchito omwe mungasankhe. Kuti akhazikitse mphamvu ya maginito, mphete yaifupi-circuit imawonjezeredwa kumtunda wachitsulo. Pambuyo AC contactor wataya mphamvu, izo amadalira masika kubwerera.

Theka lina ndilo chitsulo chosunthika, chomwe chimakhala ndi dongosolo lofanana ndi chitsulo chokhazikika, ndipo chimagwiritsidwa ntchito kuyendetsa kutsegula ndi kutseka kwa kukhudzana kwakukulu ndi kukhudzana kothandizira. The contactor pamwamba 20 amps ali okonzeka ndi arc kuzimitsa chivundikirocho, amene amagwiritsa electromagnetic mphamvu kwaiye pamene dera kulumikizidwa mwamsanga kukoka arc kuteteza kulankhula. TheAC cholumikiziraimapangidwa yonse, ndipo mawonekedwe ndi magwiridwe antchito zikuyenda bwino, koma ntchitoyo imakhala yofanana. Ziribe kanthu momwe patsogolo luso ndi, wamba AC contactor akadali udindo wake wofunika.
