Basa reSwitch yeLoad Break

Iyochinja chemutoromudziyo wekuchinja pakati pecircuit breaker ne isolation switch. Une arc extinguishing device iri nyore, iyo inogona kudimbura rated load current uye imwe overload current, asi haigone kudimbura short-circuit current.

Iyochinja chemutoroinonyanya kushandiswa kupwanya nekuvhara simba remagetsi, uye chinja chemagetsi chinogona kushandiswawo pamwe chete nefuse ine simba guru kutsiva chinopwanya magetsi. Nekuti chinja chemagetsi chiri nyore kushandisa uye mutengo wacho wakaringana, chinja chemagetsi chinoshandiswa zvakanyanya muhurongwa hwe10kV distribution network. Kusarudzwa kwakanaka kwechinja chemagetsi mudhizaini kwakakosha zvikuru kuona kuti grid yemagetsi inoshanda zvakachengeteka uye zvakavimbika.

Maitiro ekushanda kwe load switch ndeekuti: kana bhureki ravhurwa, pasi pekushanda kwechitubu chekuvhura, shaft huru inotenderera newachi. Kune rumwe rutivi, piston inofamba ichikwira nepakati pe crank-slider mechanism kuti idzvinyirire gasi; kune rumwe rutivi, kuburikidza nemaseti maviri e four-bar linkage mechanism Sisitimu yekutumira yakagadzirwa inoita kuti banga guru rivhurike kutanga, yobva yasundidzira banga re arc extinguishing kuti ivhure arc contact, uye mweya wakamanikidzwa uri mu cylinder unoburitsa arc nepa nozzle.

Pfungwa yekushanda kweswitch yemagetsi ane simba rakakwira yakafanana neyecircuit breaker. Kazhinji, mudziyo wekudzima arc wakapfava unoiswa, asi chimiro chawo chiri nyore. Mufananidzo unoratidza switch yemhepo yakamanikidzwa ine simba rakakwira. Maitiro ayo ekushanda ndeekuti: kana bhureki ravhurwa, pasi pekushanda kwechitubu chekuvhura, shaft huru inotenderera newachi. Kune rumwe rutivi, piston inofamba ichikwira nepakati pe crank-slider mechanism kuti idzvinyirire gasi.

Kune rumwe rutivi, kuburikidza nesystem yekutumira ine maseti maviri enzira yekubatanidza ine mitsetse mina, banga guru rinotanga ravhurwa, uye banga rekudzima arc rinosundidzirwa kuti rivhure arc contact, uye mweya wakamanikidzwa uri mucylinder unoburitsa arc kuburikidza nemuromo. Pakuvhara, kuburikidza neshaft huru nesystem yekutumira, banga guru nebanga rekudzima arc zvinotenderera newachi panguva imwe chete, uye arc contact inovharwa kutanga; shaft huru inoramba ichitenderera, kuitira kuti main contact ivharwe gare gare.

Munguva yekuvhara, chitubu chekuvhura chinochengeta simba panguva imwe chete. Sezvo switch yekurodha isingakwanise kutyora current yepfupi, inowanzo shandiswa pamwe chete nefuse ine simba guru remagetsi. Basa rekudzivirira current yefuse ine simba haringogumiri pakupedzisa basa rekutyora circuit chete, asiwo kuderedza zvakanyanya kupisa kunokonzerwa necurrent yepfupi uye simba remagetsi.
