Chifukwa Chake Chingwe Chotetezera Chingwe Ndi Chofunikira Pakugwira Ntchito Kwabwino？

Kapangidwe koyambira ka chingwe chamagetsi kamapangidwa ndi magawo anayi: waya wapakati (conductor), insulation layer, shielding layer ndi protective layer. Insulation layer ndi kulekanitsidwa kwa magetsi pakati pa waya wapakati ndi nthaka ndi magawo osiyanasiyana a waya wapakati kuti atsimikizire kutumiza kwa mphamvu yamagetsi, ndipo ndi gawo lofunika kwambiri la kapangidwe ka chingwe chamagetsi.

Udindo wa gawo lotetezera kutentha:

Pakati pa chingwe ndi kondakitala. Pofuna kupewa kuwonongeka kwa zida zomwe zimachitika chifukwa cha mawaya owonekera komanso kuvulaza anthu chifukwa cha mawaya omwe amaposa mphamvu ya chitetezo, gawo loteteza kutentha liyenera kuwonjezeredwa ku chingwecho. Kukana kwa magetsi kwa kondakitala wachitsulo mu chingwecho ndi kochepa kwambiri, ndipo kukana kwa magetsi kwa kondakitala ndi kwakukulu kwambiri. Chifukwa chomwe kondakitala imatha kutetezedwa ndichakuti: ma charge abwino ndi oipa mu mamolekyu a kondakitala ndi omangika kwambiri, tinthu tomwe timayendetsedwa ndi magetsi tomwe timatha kuyenda momasuka ndi ochepa kwambiri, ndipo kukana ndi kwakukulu kwambiri, kotero nthawi zambiri, mphamvu yayikulu yopangidwa ndi kayendedwe ka free charge pansi pa mphamvu yamagetsi akunja ikhoza kunyalanyazidwa, ndipo imaonedwa kuti ndi chinthu chosayendetsa magetsi. Kwa ma insulators, pali voltage yowonongeka yomwe imapatsa ma elekitironi mphamvu zokwanira kuti iwasangalatse. Voltage yowonongeka ikapitirira, zinthuzo sizimatetezanso kutentha.

Kodi makulidwe osakwanira a insulation pa chingwe amakhudza bwanji?

Fupikitsani nthawi yogwira ntchito ya waya ndi chingwe, ngati mfundo yopyapyala ya chingwe sichikukwaniritsa zofunikira, pambuyo pa ntchito yayitali, makamaka pamalo obisika mwachindunji, oviikidwa m'madzi, otseguka kapena owononga, chifukwa cha dzimbiri la nthawi yayitali la chapakati chakunja, mulingo woteteza ndi mulingo wamakina wa mfundo yopyapyala ya chingwe udzachepa. Kuzindikira kwachizolowezi kwa chikwama kapena kulephera kwa mzere pansi, mfundo yopyapyala ikhoza kusweka, mphamvu yoteteza ya chingwe idzatayika. Kuphatikiza apo, kugwiritsa ntchito kwamkati sikunganyalanyazidwe, mphamvu ya waya ndi chingwe nthawi yayitali idzapanga kutentha kwambiri, idzafupikitsa nthawi yogwira ntchito ya waya ndi chingwe. Ngati khalidwe silili bwino, lingayambitse moto ndi zoopsa zina zachitetezo.

Kuwonjezera kuuma kwa njira yoyika, mu ndondomeko yoyika muyenera kuganizira zosiya mpata, kuti kutentha komwe kumapangidwa pambuyo pa waya ndi chingwe kutayike, makulidwe a chivundikirocho ndi okhuthala kwambiri adzawonjezera kuuma kwa chivundikirocho, kotero makulidwe a chivundikirocho amafunika kutsatira miyezo yoyenera, apo ayi sichingathandize kuteteza waya ndi chingwecho. Chimodzi mwa makhalidwe a khalidwe la chinthucho chimawonekera mu mawonekedwe a chinthucho. Kaya ndi chingwe chamagetsi kapena waya wamba, khalidwe la chotenthetsera liyenera kuganiziridwa popanga, ndipo liyenera kuyang'aniridwa mosamala ndikuyesedwa.

Mwina anthu ambiri adzakhala ndi kukayikira, popeza ntchito ya chotenthetsera ndi yayikulu kwambiri, pamwamba pa chingwe chowunikira ndi chingwe chotsika mphamvu zimaphimbidwa ndi pulasitiki kapena rabara, ndipo chingwe chotentha mphamvu m'munda sichiphimbidwa ndi chotenthetsera mphamvu.

Chifukwa pakakhala magetsi ambiri, zinthu zina zomwe poyamba zimateteza kutentha, monga rabara, pulasitiki, matabwa ouma, ndi zina zotero, zidzakhalanso zowongolera kutentha, ndipo sizidzakhala ndi mphamvu yoteteza kutentha. Kuphimba kutentha pa zingwe zamagetsi amphamvu ndi kutaya ndalama ndi zinthu zina. Pamwamba pa waya wamphamvu sipaphimbidwa ndi kutentha, ndipo ngati ipachikidwa pa nsanja yayitali, ikhoza kutulutsa magetsi chifukwa chokhudzana ndi nsanja. Pofuna kupewa izi, waya wamphamvu nthawi zonse imapachikidwa pansi pa mabotolo a porcelain okhala ndi kutentha bwino, kotero kuti waya wamphamvu umakhala wotetezedwa kuchokera ku nsanja. Kuphatikiza apo, mukayika zingwe zamagetsi amphamvu, musamazikokere pansi. Kupanda kutero, chifukwa cha kukangana pakati pa waya ndi nthaka, gawo loyambirira losalala loteteza kutentha limawonongeka, ndipo pali ma burrs ambiri, omwe amatulutsa kutuluka kwa nsonga, zomwe zimapangitsa kuti kutayike.

Chingwe chotetezera kutentha chimayikidwa malinga ndi zosowa za chingwecho. Pakupanga, opanga amafunika kuwongolera makulidwe a chotetezera kutentha motsatira miyezo ya njira, kukwaniritsa kayendetsedwe kabwino ka njira, ndikuwonetsetsa kuti waya ndi chingwe zili bwino.
