Chingwe chamagetsi cholumikizidwa ndi polyethylene chotetezedwa chimagwiritsidwa ntchito kwambiri mu dongosolo lamagetsi chifukwa cha mphamvu zake zabwino zotenthetsera ndi makina, mphamvu zake zabwino zamagetsi komanso kukana dzimbiri kwa mankhwala. Chilinso ndi ubwino wa kapangidwe kosavuta, kulemera kwake kochepa, kuyika sikungolephereke ndi kutsika, ndipo chimagwiritsidwa ntchito kwambiri m'ma gridi amagetsi akumatauni, migodi, zomera zamakemikolo ndi malo ena. Kugwiritsa ntchito kutchinjiriza kwa chingwechopolyethylene yolumikizidwa, yomwe imasinthidwa ndi mankhwala kuchokera ku polyethylene yolunjika kukhala kapangidwe ka netiweki ya magawo atatu, motero imakweza kwambiri mawonekedwe a makina a polyethylene pomwe ikusunga mawonekedwe ake abwino kwambiri amagetsi. Zotsatirazi zikufotokoza kusiyana ndi ubwino pakati pa zingwe zolumikizidwa za polyethylene zotetezedwa ndi zingwe wamba zotetezedwa kuchokera mbali zosiyanasiyana.
1. Kusiyana kwa zinthu
(1) Kukana kutentha
Kutentha kwa zingwe zotetezedwa nthawi zambiri kumakhala 70°C, pomwe kutentha kwa zingwe zotetezedwa ndi polyethylene zolumikizidwa kumatha kufika 90°C kapena kupitirira apo, zomwe zimapangitsa kuti chingwecho chisatenthe kwambiri, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito m'malo ovuta kwambiri.
(2) Kunyamula katundu
Pansi pa dera lomwelo la kondakitala, mphamvu yonyamulira ya chingwe chotetezedwa cha XLPE ndi yayikulu kwambiri kuposa ya chingwe chotetezedwa chachizolowezi, chomwe chingakwaniritse dongosolo lamagetsi lomwe likufunika mphamvu yayikulu.
(3) Kuchuluka kwa ntchito
Zingwe zotetezedwa bwino zimatulutsa utsi wa poizoni wa HCl zikawotchedwa, ndipo sizingagwiritsidwe ntchito pazochitika zomwe zimafuna kupewa moto wowononga chilengedwe komanso poizoni wochepa. Chingwe chotetezedwa cha polyethylene cholumikizidwa ndi cross-linked sichili ndi halogen, chimakhala chotetezeka ku chilengedwe, choyenera kugwiritsidwa ntchito pamaneti ogawa, kukhazikitsa mafakitale ndi zochitika zina zomwe zimafuna magetsi ambiri, makamaka AC 50Hz, voltage yovomerezeka ya 6kV ~ 35kV yokhazikika yotumizira ndi kugawa.
(4) Kukhazikika kwa mankhwala
Polyethylene yolumikizidwa bwino imakhala ndi kukana kwabwino kwa mankhwala ndipo imatha kugwira ntchito bwino kwambiri m'malo okhala ndi ma acid, alkali ndi mankhwala ena, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo apadera monga zomera zamakemikolo ndi malo okhala m'nyanja.
2. Ubwino wa chingwe chotetezedwa ndi polyethylene cholumikizidwa
(1) Kukana kutentha
Polyethylene yolumikizidwa imasinthidwa pogwiritsa ntchito mankhwala kapena zinthu zakuthupi kuti isinthe kapangidwe ka molekyulu kukhala kapangidwe ka netiweki ya magawo atatu, zomwe zimapangitsa kuti zinthuzo zisamatenthe kwambiri. Poyerekeza ndi polyethylene wamba ndi polyvinyl chloride insulation, zingwe za polyethylene zolumikizidwa zimakhala zokhazikika kwambiri m'malo otentha kwambiri.
(2) Kutentha kwakukulu kwa ntchito
Kutentha kwa ntchito kwa kondakitala kumatha kufika 90 ° C, komwe ndi kokwera kuposa kwa zingwe zachikhalidwe za PVC kapena polyethylene zotetezedwa, motero kumawonjezera kwambiri mphamvu yonyamulira chingwe komanso chitetezo cha nthawi yayitali.
(3) Kapangidwe kabwino kwambiri ka makina
Chingwe chotetezedwa ndi polyethylene cholumikizidwa bwino chili ndi mphamvu zabwino zotenthetsera kutentha kwambiri, chimagwira ntchito bwino pakukalamba kwa kutentha, ndipo chimatha kusunga kukhazikika kwa makina pamalo otentha kwambiri kwa nthawi yayitali.
(4) Kulemera kopepuka, kuyika kosavuta
Kulemera kwa chingwe chotetezedwa ndi polyethylene cholumikizidwa ndi waya ndi kopepuka kuposa kwa zingwe wamba, ndipo kuyika kwake sikungochepetsedwe ndi kutsika. Ndikoyenera makamaka m'malo ovuta omangira komanso m'malo akuluakulu oyika zingwe.
(5) Kuchita bwino kwa chilengedwe:
Chingwe chotetezedwa ndi polyethylene cholumikizidwa ndi waya chilibe halogen, sichitulutsa mpweya woipa panthawi yoyaka, sichikhudza kwambiri chilengedwe, ndipo chimagwiritsidwa ntchito makamaka m'malo omwe ali ndi zofunikira kwambiri zoteteza chilengedwe.
3. Ubwino pa kukhazikitsa ndi kukonza
(1) Kulimba kwambiri
Chingwe chotetezedwa ndi polyethylene cholumikizidwa bwino chili ndi mphamvu yolimbana ndi ukalamba, choyenera kuyikidwa m'manda kwa nthawi yayitali kapena kuwonetsedwa panja, zomwe zimachepetsa kuchuluka kwa mawaya osinthidwa.
(2) Kudalirika kwamphamvu kwa kutchinjiriza
Mphamvu zabwino kwambiri zotetezera kutentha za polyethylene yolumikizidwa, yokhala ndi mphamvu yolimbana ndi magetsi ambiri komanso kusweka kwa magetsi, zimachepetsa chiopsezo cha kulephera kwa magetsi otetezera kutentha pogwiritsa ntchito magetsi ambiri.
(3) Kuchepetsa ndalama zokonzera
Chifukwa cha kukana dzimbiri komanso kukana kukalamba kwa zingwe zotetezedwa ndi polyethylene, nthawi yawo yogwirira ntchito ndi yayitali, zomwe zimachepetsa ndalama zokonzera ndi kusinthitsa tsiku ndi tsiku.
4. Ubwino wa chithandizo chatsopano chaukadaulo
M'zaka zaposachedwapa, chifukwa cha kusintha kwa ukadaulo wa zinthu za polyethylene, magwiridwe antchito ake oteteza kutentha komanso zinthu zakuthupi zakula kwambiri, monga:
Choletsa moto chowonjezera, chimatha kukwaniritsa zofunikira pa malo apadera (monga sitima yapansi panthaka, malo opangira magetsi);
Kulimba kwa kukana kuzizira, komwe kumakhala kokhazikika m'malo ozizira kwambiri;
Kudzera mu njira yatsopano yolumikizirana, njira yopangira zingwe imakhala yothandiza kwambiri komanso yosawononga chilengedwe.
Ndi ntchito yake yabwino kwambiri, zingwe zotetezedwa ndi polyethylene zolumikizidwa zili ndi udindo wofunikira kwambiri pakupereka ndi kugawa magetsi, zomwe zimapereka chisankho chotetezeka, chodalirika komanso chosawononga chilengedwe cha ma gridi amagetsi amakono m'mizinda komanso chitukuko cha mafakitale.
