Arc Chamber Kwa Ophwanya Magawo Otsika Otsika

Chipinda cha arc cha low-voltage circuit breakers, chomwe makamaka chimakhala ndi: mbale zachitsulo zooneka ngati U;Mpanda wopangidwa ndi zinthu zotetezera zomwe zimakhala zooneka ngati parallelepiped ndipo zimakhala ndi makoma awiri am'mbali, khoma lapansi, khoma lapamwamba ndi khoma lakumbuyo, makoma am'mbali amakhala ndi, mkati mwake, mipata yambiri yosiyana kuti alowetse chitsulo. mbale, pansi ndi pamwamba makoma aliyense ali ndi kutsegula kamodzi ndipo mpanda kukhala wotsegula kutsogolo.

Amadziwika kuti owumbidwa case power circuit breakers nthawi zambiri amagwiritsidwa ntchito m'mafakitale otsika mphamvu zamagetsi, mwachitsanzo, makina omwe amagwira ntchito mpaka pafupifupi 1000 Volt.Ophwanya madera omwe adanenedwa nthawi zambiri amapatsidwa kachitidwe komwe kamapangitsa kuti pakhale nthawi yomwe ikufunika kwa ogwiritsa ntchito osiyanasiyana, kulumikizana ndi kuchotsedwa kwa katunduyo, kutetezedwa kuzinthu zilizonse zachilendo, monga kudzaza ndi kufupikitsa, potsegula basi, ndi kuchotsedwa kwa dera lotetezedwa mwa kutsegula zosuntha zoyendayenda pokhudzana ndi okhazikika (kupatukana kwa galvanic) kuti akwaniritse kudzipatula kwathunthu kwa katundu pokhudzana ndi gwero la mphamvu yamagetsi.

Ntchito yovuta ya kusokoneza pakali pano (kaya mwadzina, mochulukira kapena yochepa-circuit panopa) amaperekedwa ndi wosweka dera mu gawo linalake la dera wosweka amene amapangidwa ndi otchedwa deionizing arc chipinda.Chifukwa cha kayendedwe kakutsegulira, voteji pakati pa olumikizana nawo amayambitsa kutulutsa kwa dielectric mlengalenga, zomwe zimapangitsa kuti arc yamagetsi ipangidwe mchipindacho.Arc imayendetsedwa ndi mphamvu zamagetsi ndi mphamvu zamagetsi mkati mwa mbale zazitsulo zomwe zimakonzedwa m'chipindamo, zomwe zimapangidwira kuzimitsa arc ndi kuzizira.Pakupanga ma arc, mphamvu yotulutsidwa ndi Joule effect imakhala yokwera kwambiri ndipo imayambitsa kupsinjika kwamafuta ndi makina mkati mwagawo lokhala ndi mbale.
