Zida Zapang'ono Zapang'onopang'ono Zimawonjezera Chitetezo ndi Kugwira Ntchito

Ma Axiliary Contacts (OF) amakhala ngati zizindikiritso zofunikira komanso zowongolera. Zogwirizana ndi makina MCBMakina ogwiritsira ntchito, amapereka chizindikiro chodalirika chamagetsi chowonetsera malo ophwanyidwa (OFF) kapena otsekedwa (ON). Izi ndizofunikira kwambiri pamapulogalamu owunikira akutali, makina a SCADA, kapena mabwalo olumikizirana, zomwe zimalola oyendetsa kutsimikizira momwe alili ozungulira popanda kuyang'ana mwakuthupi. Kulumikizana kwa OF kumatsimikizira kuti kuwongolera kutengera malo a wosweka kumachitidwa molondola komanso motetezeka.

Momwemonso, Alarm Contact (SD) imapereka chidziwitso chofunikira cha zochitika zinazake. Imagwira ntchito mosadalira pa Auxiliary Contact, nthawi zambiri imasintha boma pokhapokha Miniature Circuit Breaker zimayenda zokha chifukwa chakuchulukira kapena vuto lalifupi. Chizindikiro chodziwikiratu ndi chofunikira pakuzindikiritsa zolakwika, ma alarm oyambitsa, kapena makina odula mitengo kuti adziwitse ogwira ntchito yokonza kuti kulumikizidwa kwadzidzidzi kwachitika, zomwe zimathandizira kuyankha mwachangu komanso kuchepetsa nthawi yopuma. Imakwaniritsa ntchito yayikulu yoteteza ndi chidziwitso chofunikira chowunikira.

Chowonjezera cha Shunt Trip (MX) chimabweretsa kuwongolera kwamphamvu kwakutali. Chipangizo chogwiritsira ntchito solenoid chimalola Miniature Circuit Breaker kuti atsegulidwe (kugwedezeka) patali kudzera pa siginecha yamagetsi, osadalira kukhalapo kwa njira yodutsa kapena yaifupi. Izi ndizofunikira pakukhazikitsa ntchito zoyimitsa mwadzidzidzi, kuphatikiza ma alarm system (pomwe mabwalo amafunikira kuchotsedwa mphamvu mwachangu), kapena kuyimitsa kutali kuti akonze. Gawo la MX limapereka gawo lofunikira pakuwongolera magwiridwe antchito komanso kulowererapo kwa chitetezo.

Zida za OF (Axiliary Contact), SD (Alarm Contact), ndi MX (Shunt Trip) zimakweza kwambiri mawonekedwe achitetezo a MCBs wamba. Mwa kuwongolera kuyang'anira zakutali, kupereka chizindikiritso chanthawi yomweyo, ndikuthandizira kuyenda kutali, amasintha zofunikira. Miniature Circuit Breaker kukhala gawo lanzeru komanso lomvera mkati mwamagetsi ovuta. Kuphatikizika kwawo kumatsimikizira kuti machitidwe amagetsi akugwira ntchito osati mogwira mtima komanso ndi chitetezo chokwanira komanso kuwongolera, kuchepetsa zoopsa zomwe zimagwirizanitsidwa ndi zochulukira, mabwalo amfupi, ndi zoopsa zogwirira ntchito pamitundu yosiyanasiyana.
