Kodi Shielded Cable Ndi Chiyani Ndipo Chifukwa Chiyani Chingwe Chotchinga Ndi Chofunika Kwambiri?

Chingwe chotchingidwa, monga momwe dzinalo likusonyezera, ndi chingwe chokhala ndi mphamvu ya anti-external electromagnetic interference yopangidwa ngati chingwe chotumizira chokhala ndi chotchinga chotchinga. Zomwe zimatchedwa "kutchinjiriza" pamapangidwe a chingwe ndi muyeso wopititsa patsogolo kugawa kwa minda yamagetsi. The kondakitala wa chingwe wapangidwa angapo zingwe waya, amene n'zosavuta kupanga kusiyana mpweya pakati pa izo ndi wosanjikiza kutchinjiriza, ndi kondakitala pamwamba si yosalala, amene adzachititsa ndende ya magetsi munda.

1.Chingwe chotchinga chosanjikiza
(1). Onjezani chotchinga chotchinga cha semi-conductive pamwamba pa kondakitala, chomwe chimakhala chofanana ndi chotchinga chotchinga komanso cholumikizana bwino ndi wosanjikiza, kuti mupewe kutulutsa pang'ono pakati pa woyendetsa ndi wosanjikiza. Chotchinga ichi chimadziwikanso kuti chotchinga chamkati. Pakhoza kukhalanso mipata yolumikizana pakati pa kutchinjiriza pamwamba ndi m'chimake, ndipo chingwe chikapindika, chingwe chotchingira chamafuta pamapepala ndichosavuta kuyambitsa ming'alu, zomwe ndi zinthu zomwe zimayambitsa kutulutsa pang'ono.

(2). Onjezani chotchinga chotchinga cha semi-conductive pamtundu wa zotchingira, zomwe zimalumikizana bwino ndi wosanjikiza wotetezedwa komanso kuthekera kofanana ndi sheath yachitsulo, kuti mupewe kutulutsa pang'ono pakati pa wosanjikiza ndi sheath.

Pofuna kuwongolera pachimake ndikutsekereza gawo lamagetsi, zingwe zamagetsi za 6kV ndi pamwamba pa sing'anga ndi zamphamvu kwambiri nthawi zambiri zimakhala ndi chishango cha conductor ndi chishango chotchingira, ndipo zingwe zina zotsika mphamvu sizikhala ndi chishango. Pali mitundu iwiri yotchinga yotchinga: yotchinga ya semi-conductive ndi yotchinga yachitsulo.

2. Chingwe chotetezedwa
Chotchinga chotchinga cha chingwechi nthawi zambiri chimalukidwa muzitsulo zazitsulo kapena filimu yachitsulo, ndipo pali njira zosiyanasiyana zotetezera kumodzi ndi kutetezedwa kangapo. Chishango chimodzi chimatanthawuza ukonde umodzi wa chishango kapena filimu ya chishango, yomwe imatha kukulunga waya umodzi kapena zingapo. Njira yotchingira ma multi-shielding ndi kuchuluka kwa maukonde otchinjiriza, ndipo filimu yotchinga ili mu chingwe chimodzi. Zina zimagwiritsidwa ntchito kupatula kusokoneza kwa ma electromagnetic pakati pa mawaya, ndipo zina ndi zotchinga ziwiri zomwe zimagwiritsidwa ntchito kulimbitsa chitetezo. Njira yotchinga ndikuyika chinsalu chotchinga kuti chizipatula mphamvu yosokoneza ya waya wakunja.

(1).Semi-conductive chishango
Semi-conductive shielding wosanjikiza nthawi zambiri anakonza pamwamba pa kunja kwa conductive waya pachimake ndi pamwamba kunja kwa wosanjikiza kutchinjiriza, motero amatchedwa wamkati theka-conductive kutchinga wosanjikiza ndi kunja theka-conductive kutchinga wosanjikiza. Chotchinga cha semi-conductive shielding chimapangidwa ndi semi-conductive material yokhala ndi resistivity yochepa kwambiri komanso yopyapyala. The mkati theka-conductive chitetezero wosanjikiza lakonzedwa kuti yunifolomu munda magetsi pa kunja kwa kondakitala pachimake ndi kupewa tsankho kukhetsa wa kondakitala ndi kutchinjiriza chifukwa cha m'lifupi pamwamba kondakitala ndi mpweya kusiyana chifukwa cha core stranded. Chishango chakunja cha semi-conductive chimagwirizana bwino ndi kunja kwa gawo lotsekera, ndipo chimakhala chofanana ndi sheath yachitsulo kuti tipewe kutulutsa pang'ono ndi sheath yachitsulo chifukwa cha zolakwika monga ming'alu pazitsulo zotchingira chingwe.

(2). Chishango chachitsulo
Pakuti sing'anga ndi otsika voteji zingwe mphamvu popanda zitsulo m'chimake, kuwonjezera kuika theka-conductive chishango wosanjikiza, komanso kuwonjezera zitsulo chishango wosanjikiza. Chishango chachitsulo chosanjikiza nthawi zambiri chimakutidwa nditepi yamkuwakapena waya wamkuwa, womwe makamaka umagwira ntchito yoteteza magetsi.

Chifukwa chapano kudzera mu chingwe chamagetsi ndi chachikulu, mphamvu ya maginito idzapangidwa mozungulira pano, kuti isakhudze zigawo zina, kotero kuti chotchinga chotchinga chikhoza kuteteza gawo lamagetsi lamagetsi mu chingwe. Kuphatikiza apo, chingwe chotchinjiriza chingwe chingathe kuchitapo kanthu pachitetezo chapansi. Ngati chingwe chapakati chawonongeka, madzi otsekemera amatha kuyenda motsatira kayendedwe ka laminar, monga networking network, kuti ateteze chitetezo. Zitha kuwoneka kuti udindo wa chingwe chishango chosanjikiza akadali chachikulu kwambiri.
