Mukasankha chosokoneza mpweya, zizindikiro zazikulu zaukadaulo zomwe ziyenera kuyesedwa

Popanga ndi kusankha ma air circuit breaker, zizindikiro zazikulu zaukadaulo zomwe ziyenera kuyesedwa ndi izi. Zizindikiro zaukadaulo izi zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti makina amagetsi omwe amayikidwa ma air circuit breaker ndi otetezeka komanso ogwira ntchito bwino.

Choyamba, kuwunika kwa voltage ya chipangizochochoswa dera la mpweyandi chinthu chofunika kuganizira.ACBziyenera kugwirizana ndi zofunikira za magetsi a dongosolo lamagetsi. Ma voltage omwe ali ndi ma rated ndi AC200 mpaka 690V ndi DC250 mpaka 400V, kotero magetsi omwe ali ndi ma rated a air circuit breaker ayenera kufanana ndi magetsi a dongosolo.

Chizindikiro china chofunikira chaukadaulo ndi mphamvu yoyesedwa (Inm) ya chimango chotseka ma circuit breaker cha low-voltage. Mitundu yosiyanasiyana ya ma brand ili ndi mphamvu yoyesedwa yosiyana ndipo ndikofunikira kuyang'ananso mosamala zambiri zaukadaulo za chinthucho kuti zitsimikizire kuti chikukwaniritsa zofunikira za makina amagetsi.

Kuchuluka kwa magetsi (In) komwe kulipo pakali pano kwa chopalira magetsi chochepa ndi chinthu chofunikira kuganizira. Kusankha kuyenera kutengera mphamvu ya transformer (kV·A) yopangidwa ndi kusanthula mwatsatanetsatane deta yaukadaulo ya chinthu chofunikira.

Kuchuluka kwa mphamvu yogwirira ntchito (Ics) ndi chizindikiro chofunikira cha momwe chophwanyira mpweya chimagwirira ntchito komanso kudalirika kwake. Ndikofunikira kusankha chinthu chomwe chili ndi mphamvu yokwanira yophwanyira kutengera kuchuluka kwa katundu, mtundu wa kapangidwe kake komanso ndalama zomwe zingagwiritsidwe ntchito.

Kuphatikiza apo, mphamvu yothyola mpweya (Icu), mphamvu yothira mpweya (Icw), kuchuluka kwa ma poles, ndi zina zotero, zonsezi ndi zizindikiro zofunika kwambiri zomwe ziyenera kuyesedwa posankha chothyola mpweya.

Powunikanso zofunikira izi, ndikofunikira kuganizira zofunikira ndi makhalidwe enieni a dongosolo lamagetsi lomwe chotsukira mpweya chimayikidwamo. Mwa kuwunika mosamala zofunikira izi, chotsukira mpweya chimatha kusankhidwa kuti chigwirizane ndi zosowa za dongosolo lanu lamagetsi, kuonetsetsa kuti lili ndi chitetezo, kudalirika komanso magwiridwe antchito abwino kwambiri.
