Makina ndi zida zambiri zamafakitale, monga makina onyamula oyimirira, makina oyika m'malo, zida zazing'ono zopangira magalimoto, ndi zina zambiri, zimafuna kuti spindle yamakina ayimitsidwe molondola pamalo enaake ikayimitsidwa. Pa nthawi yomweyi, chifukwa cha mpikisano woopsa wa msika, makasitomala akuyembekeza kugwiritsa ntchito njira zothetsera mavuto kuti athetse vuto la kuima kolondola.

Chifukwa chachikulu cholumikizira cha 380V AC chimayaka pamagetsi ndi chifukwa cha kusankha kolakwika kwa koyilo. Mphamvu ya koyilo ya AC contactor iyenera kufanana ndi mphamvu yamagetsi.

Kodi ma circuit breakers, load switch and disconnectors ndi chiyani? Mwinamwake ambiri ogwira ntchito zamagetsi ndi omveka bwino. Koma zikafika pa kusiyana ndi kugwiritsa ntchito pakati pa ophwanya dera, zosinthira katundu ndi zolumikizira, ambiri ogwira ntchito zamagetsi amatha kudziwa chimodzi koma osati chinacho, komanso kwa oyambitsa magetsi, sadziwa zomwe angafunse. Tonse tikudziwa kuti wowononga dera akhoza kutseka, kunyamula ndi kuswa zomwe zikuchitika pansi pa nthawi yanthawi zonse, ndipo akhoza kutseka, kunyamula ndi kuthyola zamakono pansi pazikhalidwe zachilendo (kuphatikizapo nthawi yochepa) mkati mwa nthawi yeniyeni. Kusinthana kwa katundu ndi chipangizo chosinthira pakati pa wowononga dera ndi chosinthira chodzipatula. Ili ndi chipangizo chozimitsa cha arc chosavuta, chomwe chimatha kudula kuchuluka kwa katundu wapano ndi kuchuluka kwanthawi yayitali, koma sikungathe kuletsa njira yachidule.

Knob ndi toggle circuit breakers ndi masiwichi awiri omwe amapezeka pamakina amagetsi. Ophwanya ma knob amagwiritsa ntchito knob yozungulira kuti aziwongolera bwino, nthawi zambiri m'malo opangira magetsi ndi ma lab. Amangoyenda molakwika, ndi osavuta kugwiritsa ntchito, otsika mtengo, koma amachedwa pakachitika ngozi. Toggle breaker (kankhira-batani) amasintha madera mwachangu kudzera mabatani, oyenera mafunde ang'onoang'ono komanso kudula mphamvu mwachangu, ngati kuyimitsidwa mwadzidzidzi. Kusankha kumatengera zosowa za pulogalamu: knob kuti muwongolere bwino, sinthani kuti mudule mwachangu. Ubwino ndi magwiridwe antchito ziyenera kukwaniritsa miyezo mosasamala za mtundu.
