Kodi chingwe gland gland ndi chiyani?
Pansi pamiyezo ya IEC, pali mitundu iwiri ikuluikulu ya chingwe cha gland molingana ndi zida zamakina, zomwe sizikhala ndi zida za chingwe cholumikizira ndi chingwe chonyamula zida.
Kodi chingwe cha armored ndi chiyani?
Pogawa mphamvu zamagetsi, chingwe chokhala ndi zida nthawi zambiri chimatanthawuza chingwe chachitsulo chokhala ndi zida (SWA) chomwe ndi chingwe chamagetsi cholimba chomwe chimapangidwira kuti chizipereka magetsi a mains.
Chingwe cha swa chimapangidwa ndi conductor, insulation, zofunda, zida ndi sheath.Mosiyana ndi chingwe chopanda zida, chingwe chokhala ndi zida chawonjezera zida zoteteza zomwe zimathandiza kuteteza pachimake cha chingwe.
Ntchito zazikulu za glands zonyamula zida:
1.Kutetezedwa ku chilengedwe â kumangiriza chingwe chakunja kuti muteteze fumbi, tinthu tating'onoting'ono ndi chinyezi kuchokera m'bokosi lamagetsi kapena m'kati.
2.Earth continuity â ngati chingwe chonyamula zida chili chopangidwa ndi chitsulo, chingathe kuyesedwa ngati dziko lipitilirabe.
3.Kuteteza chingwe â kumathandizira kukana kutulutsa chingwe pamene chingwe chakhudzidwa.
Nthawi zambiri malo ogwiritsira ntchito zingwe zopangira zida zokhala ndi zida zimakhala zoyipa kuposa zingwe zopanda zida zopanda zida, chifukwa zingwe zokhala ndi zida nthawi zonse zimakwiriridwa mwachindunji pansi, pakuyika panja kapena munjira.
Jixiang cholumikizira ndi katswiri wopanga mitundu yosiyanasiyana ya tiziwalo timene timatulutsa zingwe ndi zolumikizira chingwe. Mutha kupeza mtundu wodziwika bwino wa chingwe chonyamula zida monga pansipa:
CW chingwe glands amagwiritsidwa ntchito panja ntchito, kutsirizitsa ndi otetezedwa chingwe armoring ndi kunja chisindikizo grips m'chimake cha chingwe motero kuonetsetsa makina mphamvu.
ndi kusalekeza kwa dziko lapansi komanso ngati kuli kofunikira kupereka chisindikizo cha IP66 chokhala ndi chikwama chakunja cha chingwe.
