Mapangidwe oyambira a waya ndi chingwe amaphatikiza kondakitala, kutchinjiriza, kutchingira, sheath ndi mbali zina.
1. Kondakitala
Ntchito: Kondakitala ndi gawo la waya ndi chingwe chomwe chimatumiza mphamvu zamagetsi (maginito), chidziwitso ndikuzindikira magwiridwe antchito amagetsi amagetsi.
Zakuthupi: Pali makamaka ma conductor osatsekedwa, monga mkuwa, aluminium, aloyi yamkuwa, aloyi ya aluminium; zopangira zitsulo, monga mkuwa wothira, mkuwa wopangidwa ndi siliva, mkuwa wa nickel-plated; zitsulo zovala zitsulo, monga zitsulo zopangidwa ndi mkuwa, aluminiyamu yovala mkuwa, zitsulo za aluminiyumu, ndi zina zotero.
2. Insulation
Ntchito: Chotchinga chotchinga chimakutidwa mozungulira kondakitala kapena chowonjezera cha kondakitala (monga tepi ya refractory mica), ndipo ntchito yake ndikupatula kondakitala kunyamula voteji yofananira ndikuletsa kutayikira pano.
Zida zomwe zimagwiritsidwa ntchito kwambiri pakutchinjiriza kutulutsa ndi polyvinyl chloride (PVC), polyethylene (PE), polyethylene yolumikizana ndi (XLPE), polyolefin yotsika utsi ya halogen-free flame retardant polyolefin (LSZH/HFFR), fluoroplastics, thermoplastic elasticity (TPE), mphira wa silikoni (SR), mphira wa ethylene propylene (EPM/EPDM), etc.
3. Kuteteza
Ntchito: Chotchinga chotchinga chomwe chimagwiritsidwa ntchito pamawaya ndi chingwe chimakhala ndi malingaliro awiri osiyana.
Choyamba, mawonekedwe a mawaya ndi zingwe zomwe zimatumiza mafunde amagetsi othamanga kwambiri (monga ma frequency a wailesi, zingwe zamagetsi) kapena mafunde ofooka (monga zingwe zamakina) amatchedwa electromagnetic shielding. Cholinga chake ndikuletsa kusokoneza kwa mafunde akunja a electromagnetic, kapena kuletsa ma siginecha apamwamba kwambiri mu chingwe kuti zisasokoneze dziko lakunja, ndikuletsa kusokoneza pakati pa ma waya awiriwa.
Chachiwiri, kapangidwe ka sing'anga ndi mkulu voteji mphamvu zingwe kuti equalize munda magetsi pa kondakitala pamwamba kapena insulating pamwamba amatchedwa electric field shielding. Kunena zoona, chitetezo chamagetsi sichifuna ntchito ya "kutchinjiriza", koma imangogwira ntchito ya homogenizing magetsi. Chishango chomwe chimazungulira chingwe nthawi zambiri chimakhala chokhazikika.
* Electromagnetic shielding kapangidwe ndi zida
① Zishango zolukidwa: makamaka amagwiritsa ntchito waya wopanda mkuwa, waya wokutidwa ndi malata, waya wamkuwa wasiliva, waya wa aluminiyamu-magnesium aloyi, tepi yosalala yamkuwa, tepi yasiliva-yokutidwa ndi siliva, ndi zina. peyala kapena chingwe pachimake;
② Kutchinga kwa tepi yamkuwa: gwiritsani ntchito tepi yofewa yamkuwa kuphimba kapena kukulunga molunjika kunja kwa pakati pa chingwe;
③ Chotchinga chachitsulo chophatikizika chachitsulo: gwiritsani ntchito zojambulazo za aluminiyamu tepi ya Mylar kapena zojambula zamkuwa tepi ya Mylar kukulunga mozungulira kapena kukulunga molunjika mawaya kapena pakati pa chingwe;
④ Chitetezo chokwanira: Kugwiritsa ntchito mozama ndi mitundu yosiyanasiyana ya zishango.Mwachitsanzo, kulungani (1-4) mawaya amkuwa oonda molunjika mutatha kukulunga ndi zojambulazo za aluminiyamu tepi ya Mylar. Mawaya amkuwa amatha kuwonjezera mphamvu ya conduction ya chitetezo;
⑤ Zishango zosiyana + zotchinga zonse: waya uliwonse kapena gulu la mawaya amatetezedwa ndi zojambulazo za aluminiyamu tepi ya Mylar kapena waya wamkuwa wolukidwa padera, ndiyeno chishango chonsecho chimawonjezeredwa pambuyo pa cabling;
⑥ Zotchingira zotchinga: Gwiritsani ntchito waya woonda wamkuwa, tepi yathyathyathya yamkuwa, ndi zina zambiri kuti muzungulire pakati pa waya wotsekeredwa, mawaya awiri kapena pakati pa chingwe.
* Mapangidwe achitetezo chamagetsi ndi zida
Semi-conductive shielding: Pazingwe zamagetsi za 6kV ndi kupitilira apo, chotchinga chocheperako cha semi-conductive chimangiriridwa pamwamba pa kondakitala ndi malo oteteza. Chotchinga chotchinga cha conductor ndi chosanjikiza chowonjezera cha semi-conductive. Chotchinga cha kondakitala chokhala ndi gawo lalikulu la 500mm² ndi pamwamba nthawi zambiri chimakhala chopangidwa ndi tepi ya semi-conductive komanso wosanjikiza wotuluka. The insulating chishango wosanjikiza ndi extruded dongosolo;
Kukulunga kwa waya wa mkuwa: Waya wamkuwa wozungulira umagwiritsidwa ntchito kwambiri pakukulunga molunjika, ndipo wosanjikiza wakunja amalangidwa mobwerera ndikumangidwa ndi tepi yamkuwa kapena waya wamkuwa. Kapangidwe kamtunduwu nthawi zambiri amagwiritsidwa ntchito pazingwe zokhala ndi magetsi amfupi, monga zingwe zazikulu za 35kV. chingwe cha mphamvu imodzi;
Kukulunga kwa tepi yamkuwa: kukulunga ndi tepi yofewa yamkuwa;
④ Chophimba cha aluminiyamu chamalata: Chimatengera kukulunga kotentha kapena aluminium tepi yotchinga kotalika, kuwotcherera, embossing, ndi zina zotere. Zotchingira zamtunduwu zimakhalanso ndi zotchingira bwino kwambiri zamadzi, ndipo zimagwiritsidwa ntchito makamaka pazingwe zamphamvu zamphamvu kwambiri komanso zamphamvu kwambiri.
4. M'chimake
Ntchito ya sheath ndi kuteteza chingwe, ndipo pachimake ndi kuteteza kutsekemera. Chifukwa cha kusinthasintha kwa malo ogwiritsira ntchito, mikhalidwe yogwiritsira ntchito komanso zofunikira za ogwiritsa ntchito. Chifukwa chake, mitundu, mawonekedwe ndi magwiridwe antchito a kamangidwe ka sheathing ndizosiyanasiyana, zomwe zitha kufotokozedwa mwachidule m'magulu atatu:
Chimodzi ndicho kuteteza nyengo yakunja, mphamvu zamakina apanthawi ndi nthawi, ndi chitetezo chambiri chomwe chimafunikira chitetezo chosindikizira (monga kupewa kulowerera kwa nthunzi yamadzi ndi mpweya woipa); Ngati pali mphamvu yakunja yamakina kapena kunyamula kulemera kwa chingwe, payenera kukhala gawo loteteza la zida zachitsulo; chachitatu ndi chitetezo wosanjikiza kapangidwe ndi zofunika zapadera.
Chifukwa chake, mawonekedwe a waya ndi chingwe nthawi zambiri amagawidwa m'magulu awiri: sheath (sleeve) ndi sheath yakunja. Kapangidwe ka m'chimake wamkati ndi yosavuta, pamene m'chimake akunja zikuphatikizapo zitsulo wosanjikiza zida wosanjikiza ndi mkati akalowa wosanjikiza (kuteteza zida wosanjikiza kuwononga mkati m'chimake wosanjikiza), ndi m'chimake akunja amene kuteteza wosanjikiza zida, etc. . Pazofunikira zosiyanasiyana zapadera monga kuletsa moto, kukana moto, anti-tizilombo (chiswe), anti-nyama (kuluma makoswe, kujowina mbalame), ndi zina zotero, zambiri zimathetsedwa powonjezera mankhwala osiyanasiyana ku sheath yakunja; ochepa ayenera kuwonjezera zofunikira mu mawonekedwe akunja a sheath..
Zida zomwe zimagwiritsidwa ntchito kwambiri ndi:
Polyvinyl chloride (PVC), polyethylene (PE), polyperfluoroethylene propylene (FEP), low smoke halogen free flame retardant polyolefin (LSZH/HFFR), thermoplastic elastomer (TPE)
