Zigawo ndi mfundo yogwirira ntchito ya AC contactor

Zolumikizira za ACndi gawo lofunika kwambiri pakugwira ntchito kwa magetsi ambiri. Amagwira ntchito yofunika kwambiri pakulamulira kuyenda kwa magetsi ndikuwonetsetsa kuti zipangizo ndi zida zosiyanasiyana zikuyenda bwino. M'nkhaniyi, tikambirana mozama za zigawo ndi mfundo zogwirira ntchito za ma contactor a AC, ndikufotokozera kufunika kwawo ndi ntchito zawo.

Cholumikizira cha AC chimakhala ndi zigawo zinayi zofunika zomwe zimagwira ntchito limodzi kuti zigwire ntchito yake yomwe ikufunidwa. Gawo loyamba ndi dongosolo la maginito, lomwe limakhala ndi cholumikizira chokopa, maziko achitsulo oyenda, ndi maziko achitsulo osasinthasintha. Cholumikizira chokopa chikapatsidwa mphamvu, chimapanga mphamvu yamagetsi, yomwe imakoka maziko achitsulo oyenda kupita ku maziko achitsulo osasinthasintha. Kuyenda kumeneku ndikofunikira kwambiri kuti cholumikiziracho chigwire ntchito bwino.

Gawo lachiwiri la AC contactor ndi dongosolo lolumikizirana. Lili ndi magulu atatu a ma contactor akuluakulu ndi gulu limodzi kapena awiri a ma contact othandizira omwe nthawi zambiri amakhala otseguka komanso otsekedwa. Ma contact awa amalumikizidwa ku chitsulo choyenda ndipo amalumikizidwa bwino kwambiri. Mphamvu yamagetsi ikakoka chitsulo, imayendetsa ma contact pamodzi, zomwe zimapangitsa kuti atseke. Izi zimapangitsa kuti magetsi aziyenda kudzera mu contactor, zomwe zimathandiza kuti zida kapena zipangizo zomwe zalumikizidwa nazo zigwiritsidwe ntchito.

Pofuna kuonetsetsa kuti cholumikizira cha AC chikugwira ntchito bwino, chili ndi chipangizo chozimitsira arc, chomwe chimapanga gawo lachitatu. Izi nthawi zambiri zimapezeka mu zolumikizira zazikulu. Arc imapangidwa pamene cholumikizira chachikulu chikugwiritsidwa ntchito ndi mphamvu yayikulu kenako nkutsegulidwa. Chipangizo chozimitsira arc chimayang'anira kudula arc mwachangu, kuteteza kuwonongeka kwa zolumikizira zazikulu ndikulekanitsidwa bwino.

Gawo lachinayi komanso lomaliza lacholumikizira cha ACIli ndi chotetezera kutentha ndi zinthu zina monga masipiringi, njira zotumizira magetsi, mphete zazifupi ndi ma terminal. Zinthu izi ndizofunikira kwambiri popereka chitetezo ndi kutetezera kuti contactor igwire ntchito bwino komanso nthawi yogwira ntchito.

Kumvetsetsa momwe ma contactor a AC amagwirira ntchito ndikofunikira kwambiri kuti timvetsetse momwe amagwirira ntchito. Pamene coil mu contactor yapatsidwa mphamvu, static iron core imapanga mphamvu yamagetsi. Mphamvu imeneyi imakoka chitsulo choyenda pakati kupita ku chitsulo chosasuntha, zomwe zimapangitsa kuti ma contactor atseke. Zotsatira zake, AC contactor imayatsidwa, dera limalumikizidwa, ndipo mphamvu yamagetsi imatuluka.

M'malo mwake, pamene coil yachotsedwa mphamvu kapena kuchotsedwa, mphamvu yamagetsi yopangidwa ndi static iron core siiliponso. Poyankha izi, shine yosuntha yachitsulo imasiyana ndi shine yosasunthika yachitsulo chifukwa cha mphamvu ya reaction ya kasupe. Zotsatira zake, zolumikizira zimatsegulidwa ndipo magetsi opita ku chipangizo cholumikizidwa amadulidwa. Izi zimachotsa bwino dera ndikuwonetsetsa kuti dongosolo lamagetsi ndi lotetezeka.

Mwachidule, cholumikizira cha AC chimakhala ndi zigawo zinayi zofunika zomwe zimagwira ntchito mogwirizana kuti ziwongolere kuyenda kwa magetsi. Kugwira ntchito kwawo moyenera ndikofunikira kwambiri pakugwira bwino ntchito kwa makonzedwe ndi zida zosiyanasiyana. Kumvetsetsa kapangidwe kake ndi mfundo zogwirira ntchito za ma contactor a AC kumatithandiza kumvetsetsa kufunika kwawo ndikuwonetsetsa kuti akugwiritsidwa ntchito bwino kwambiri m'makina amagetsi.
