Kodi Chingwe Chotetezedwa N'chiyani Ndipo N'chifukwa Chiyani Chingwe Choteteza Ndi Chofunika Kwambiri?

Chingwe chotetezedwa, monga momwe dzinalo likusonyezera, ndi chingwe chokhala ndi mphamvu yolimbana ndi kusokoneza kwa maginito amagetsi yopangidwa ngati chingwe chotumizira ndi gawo loteteza. Chomwe chimatchedwa "chitetezo" pa kapangidwe ka chingwe ndi njira yowonjezerera kufalikira kwa minda yamagetsi. Choyendetsa chingwecho chimapangidwa ndi zingwe zingapo za waya, zomwe zimakhala zosavuta kupanga mpata wa mpweya pakati pake ndi gawo loteteza, ndipo pamwamba pa chowongolera sichili chosalala, zomwe zimapangitsa kuti mphamvu yamagetsi ikhale yochuluka.

1.Chingwe choteteza chingwe
(1). Onjezani gawo loteteza la zinthu zoyendetsera mpweya zomwe zimakhala ndi mphamvu zochepa pamwamba pa kondakitala, zomwe zimakhala zogwirizana ndi kondakitala woteteza komanso zogwirizana bwino ndi gawo loteteza mpweya, kuti mupewe kutuluka pang'ono pakati pa kondakitala ndi gawo loteteza mpweya. Gawo loteteza mpweya limeneli limadziwikanso kuti gawo lamkati loteteza mpweya. Pakhoza kukhalanso mipata pakati pa pamwamba pa malo otetezera mpweya ndi chivundikiro, ndipo chingwe chikapindika, pamwamba pa chingwe cha pepala loteteza mpweya kumakhala kosavuta kuyambitsa ming'alu, zomwe ndi zinthu zomwe zimayambitsa kutuluka pang'ono.

(2). Onjezani gawo loteteza la zinthu zoyendetsera mpweya pamwamba pa gawo loteteza mpweya, lomwe limakhudzana bwino ndi gawo loteteza mpweya komanso mphamvu yofanana ndi gawo lachitsulo, kuti mupewe kutuluka pang'ono pakati pa gawo loteteza mpweya ndi gawolo.

Kuti ziyendetse bwino pakati ndikuteteza mphamvu zamagetsi, zingwe zamagetsi za 6kV ndi zapakati komanso zapamwamba nthawi zambiri zimakhala ndi chishango cha conductor ndi chishango choteteza mphamvu, ndipo zingwe zina za low-voltage zilibe chishango. Pali mitundu iwiri ya zishango zoteteza: zishango zoteteza mphamvu ndi zishango zachitsulo.

2. Chingwe chotetezedwa
Chingwe chotchingira cha chingwechi chimakulungidwa kwambiri mu netiweki ya mawaya achitsulo kapena filimu yachitsulo, ndipo pali njira zosiyanasiyana zotchingira chimodzi ndi zotchingira zingapo. Chingwe chimodzi chimatanthauza ukonde umodzi kapena filimu ya chishango, yomwe imatha kukulunga waya umodzi kapena ingapo. Njira yotchingira zambiri ndi maukonde ambiri otchingira, ndipo filimu yotchingira ili mu chingwe chimodzi. Zina zimagwiritsidwa ntchito kupatula kusokoneza kwa mawaya amagetsi, ndipo zina ndi zotchingira ziwiri zomwe zimagwiritsidwa ntchito kulimbitsa mphamvu yotchingira. Njira yotchingira ndikutsitsa gawo lotchingira kuti lichotse mphamvu yosokoneza ya waya wakunja.

(1). Chishango chowongolera mpweya
Gawo lotchingira la semi-conductive nthawi zambiri limayikidwa pamwamba pa waya woyendetsa ndi pamwamba pa gawo lotchingira, motsatana limatchedwa gawo lotchingira lamkati la semi-conductive ndi gawo lakunja la semi-conductive shielding. Gawo lotchingira la semi-conductive limapangidwa ndi zinthu zotchingira za semi-conductive zomwe zimakhala ndi resistivity yochepa kwambiri komanso makulidwe ochepa. Gawo lotchingira lamkati la semi-conductive limapangidwa kuti ligwirizane ndi mphamvu yamagetsi pamwamba pa gawo lotchingira ndikupewa kutulutsa pang'ono kwa kondakitala ndi kutchingira chifukwa cha kusalingana kwa pamwamba pa kondakitala ndi mpata wa mpweya womwe umayambitsidwa ndi gawo losweka. Chishango chakunja cha semi-conductive chimakhudzana bwino ndi pamwamba pa gawo lotchingira, ndipo chimakhala chogwirizana ndi gawo lachitsulo kuti chipewe kutuluka pang'ono ndi gawo lachitsulo chifukwa cha zolakwika monga ming'alu pamwamba pa chingwe chotchingira.

(2). Chishango chachitsulo
Pa zingwe zamagetsi zapakati ndi zochepa zopanda zipolopolo zachitsulo, kuwonjezera pa kukhazikitsa gawo la chishango choyendetsa mpweya, komanso kuwonjezera gawo la chishango chachitsulo. Gawo la chishango chachitsulo nthawi zambiri limakulungidwa nditepi yamkuwakapena waya wamkuwa, womwe umagwira ntchito makamaka yoteteza mphamvu yamagetsi.

Popeza mphamvu yamagetsi kudzera mu chingwe chamagetsi ndi yayikulu, mphamvu yamagetsi imapangidwa mozungulira mphamvu yamagetsi, kuti isakhudze zigawo zina, kotero gawo loteteza limatha kuteteza mphamvu yamagetsi iyi mu chingwe. Kuphatikiza apo, gawo loteteza chingwe limatha kugwira ntchito inayake poteteza nthaka. Ngati pakati pa chingwe pawonongeka, mphamvu yotuluka imatha kuyenda motsatira njira yotetezera, monga netiweki yoteteza nthaka, kuti igwire ntchito yoteteza chitetezo. Zikuoneka kuti ntchito ya gawo loteteza chingwe ikadali yayikulu kwambiri.
