GL Technology Posachedwapa OPGW Kukhazikitsa Buku
Tsopano, Tiyeni tipitilize kuphunzira kwathuOPGW Hardware ndi ChalkKuyika lero.
Ikani zopangira ndi zowonjezera mu maola 48 mutatha kulimbitsa zingwe mu gawo la zomangika kuti mupewe kuwonongeka kosafunikira kwa ulusi chifukwa cha kutopa kwa chingwe, chifukwa chingwecho chimatha kugwedezeka mosavuta kapena kugwedezeka mu pulley.Zopangira ndi zowonjezera za OPGW nthawi zambiri zimaphatikizapo: zolimbitsa thupi,
kuyimitsidwa koyimitsidwa, waya wapadera wapadziko lapansi, damper yogwedera, ndodo zankhondo, chowongolera chotsitsa, bokosi lolumikizana ndi zina zotero.
1. Kuyika kwa tension clamp
tension clamp ndiye chida chofunikira kwambiri pakuyika OPGW chomwe sichimangokonza chingwe pamtengo ndi nsanja komanso kumapangitsa kuti pakhale kupanikizika kwambiri komanso kumagwira chingwe mwamphamvu pomwe sichikupitilira mphamvu yakumbali ya OPGW.Chingwe champhamvu chimagwiritsidwa ntchito mu nsanja yomaliza, nsanja yamakona yopitilira 15 °, cabling.
nsanja kapena pole tower ya kusiyana kwakukulu kokwera.Chingwe cholumikizira chisanachitike chimapangidwa ndi waya wamkati, waya wakunja, thimble, bawuti, nati ndi zina zotero.
Masitepe oyika:
A. Konzani zida munsanja pambuyo poti chingwe cha arc chisinthidwe ndi zida za putt-off.
B. Kokani mawaya omangika akunja omwe amalumikizidwa ndi lupu lokhala ngati mtima la zida zoyendera.Pangani waya womangika mofanana ndi chingwe ndikuyika chingwe pamalo opaka utoto pawaya.
C. Lumikizani mawaya omangika mkati ndi chizindikiro pa chingwe, ndiyeno, tembenuzani gulu loyamba la waya womangika pa chingwe.Sonkhanitsani mawaya ena omwe amamangirirapo kapena ikani choyikapo pansi ndi chizindikiro cha utoto kuti mutsimikizire kuti mawaya onse omangika kale akulumikizana molimba ndipo malekezero ake ndi odulidwa.
wokwanira bwino.Pewani waya wokhazikika kuti asasunthike pochita mopambanitsa kuti asakhudze mtunda wa mabawuti.
D. Ikani waya womangika pa thimble ndi kufananiza chizindikiro cha mbali ya waya wolowera kunja ndi m'khosi wa waya wolowera mkati.Kenako, tembenuzani waya wolowera kunja.Sungani danga molingana mosasamala kanthu za reel kuchokera ku gawo limodzi kapena magawo awiri.
2 Kuyika kwa kuyimitsidwa koletsa
Pre-stranding suspension clamp imagwiritsidwa ntchito kupachika chingwe m'munsi, chomwe chimapangidwa ndi waya wamkati, waya wotsekeka, chingwe cha rabara, kutumphuka kwa alloy ingot, bawuti, nati ndi gasket.
Masitepe oyika:
A. Chongani poyimitsidwa pa chingwe cha OPGW ndikuwongolera waya wolowera mkati kuchokera kuchigawo chapakati, chomwe chalembedwa.Gwiritsani ntchito manja osati zida kuti musunthire mbali yomaliza mutatha kugwedeza mawaya onse mkati mwake.
B. Ikani pakati pa mawaya omangira chapakati pakatikati pa mphira wamba ndikumangika ndi tepi yachipongwe, Kenako, ikani waya womangira panja pa chingwe chotchinga pamodzi ndi mapindikira kapena ikani pansi Hake.Sungani danga molingana ndipo pewani kudutsana.
C. Ikani pakati pa kusweka kwa pakati pa stranding mawaya mapeto kung'amba bawuti ndi kukonza.Ndiyeno gwirizanitsani ndi kuyimitsidwa chokhazikika, kung'amba bawuti ndi kupachika pa nsanja.
3. Kuyika kwa damper yogwedezeka
Damper ya vibration imagwiritsidwa ntchito kuthetsa kapena kumasula kugwedezeka komwe kumachitika chifukwa cha mitundu yonse yazinthu panthawi ya OPGW kuti ateteze chingwe cha OPGW ndikutalikitsa moyo wa chingwe.
3.1 Mfundo yogawa nambala yoyika:
Chiwerengero cha damper kugwedera amaperekedwa malinga ndi mfundo zotsatirazi: span≤250m: 2 seti;kutalika: 250 ~ 500m (kuphatikiza 500m), ma seti 4;kutalika: 500 ~ 750m (kuphatikiza 750m), ma seti 6;pamene kutalika kwadutsa 1000m, ndondomeko yogawa iyenera kusinthidwa malinga ndi momwe mizere ilili.
3.2 Kuyika malo
(1) Fomula yowerengera:
Fomula yowerengera:
D: chingwe awiri (mm)
T : chingwe pachaka avareji kupsinjika (kN), nthawi zambiri 20% RTS
M: kulemera kwa chingwe (kg/km)
(2) Poyambira pa kugwedera damper unsembe: poyambira L1 ndi pakati mzere kuyimitsidwa achepetsa ndi mzere pakati pa thimble thimble;poyambira L2 ndiye pakatikati pa damper yoyamba kugwedera, poyambira L3 ndiye pakatikati pa damper yachiwiri yogwedezeka, ndi zina zotero.
(3) Damper yoyamba yogwedera iyenera kukhazikitsidwa pa waya wamkati wazinthu, ndi zina.
amaikidwa pa ndodo zapadera za zida kuchokera ku chotenthetsera chachiwiri cha vibration.
4. Kuyika kwa waya wa nthaka
Waya wapadziko lapansi umagwiritsidwa ntchito makamaka popereka mwayi wopeza magetsi odulira nthawi yayitali OPGW ikukhazikika.Imamangidwa ndi waya wa alloy ndipo imalumikizidwa ndi zida zokhala ndi chotchingira chofananira kapena fanizo ndipo mbali inayo imalumikizidwa ndi dzenje loyambira nsanja.Kuyika kwa waya wapadziko lapansi kuyenera kukhala kokongola, kokhala ndi kutalika koyenera, popanda kupindika kapena kupindika.Malo olumikizirana ayenera kukhala olumikizana bwino ndikukhala ogwirizana
mizere yonse.
5. Kuyika kwa downlead clamp, tray cable ndi joint box
Chingwe pa splicing mfundo pa nsanja ayenera spliced pambuyo kutsogolera pansi.Pambali ziwiri za dziko lapansi waya kuima kwa nsanja kwa nsanja thupi ndiyeno kutsogolera pamodzi mkati mwa nsanja thupi.Utali wopindika wa njira yomwe kutsika ukudutsa sikuyenera kuchepera 1m, ndipo utali wopindika wocheperako uyenera kulonjezedwa pogwira ntchito, nthawi zambiri kupitilira 0.5m.Chingwecho chikatsogoleredwera pansi, clamp yotsitsa imagwiritsidwa ntchito kumangiriza
chingwe pa mfundo mfundo kapena zinthu zina za chingwe.Chingwe chotsitsa chamtundu wa nangula chiyenera kugwiritsidwa ntchito ngati chili ndi lead pamtengo wa konkriti (monga
monga akatembenuka siteshoni, mphamvu zomera dongosolo). Chingwe downlead ayenera molunjika ndi wokongola.Bokosi lolumikizana ndi thireyi ya chingwe ziyenera kuyikidwa pamalo oyenera pansanjayo, ndipo pafupifupi 8 ~ 10m pamwamba pa nsanjayo.Kuyikako kuyenera kukhala kolimba ndipo mizere yonse ikhale yolumikizana.
