Chingwe cha OPGW, yomwe imadziwikanso kuti waya wapansi wopangidwa ndi ulusi ...

Chingwe cha OPGW chimakulungidwa ndi waya wachitsulo, kotero kuti chingwecho chikhale chodalirika, chokhazikika komanso cholimba, chifukwa waya wapansi ndi chingwe cholumikizidwa pamwamba zimaphatikizidwa kukhala chimodzi, poyerekeza ndi kugwiritsa ntchito njira zina za chingwe, zonse ziwiri zimafupikitsa nthawi yomanga ndikusunga ndalama zomangira. Kuphatikiza apo, ngati OPGW yopangidwa ndi waya wachitsulo wokutidwa ndi aluminiyamu kapena waya wa aluminiyamu ikugwiritsidwa ntchito, ndizofanana ndi kukhazikitsa waya wabwino woyendetsa pamwamba, womwe ungalandire zabwino zambiri monga kuchepetsa mphamvu yobisika ya chingwe chotumizira, kuchepetsa mphamvu yochulukirapo, komanso kukonza kusokoneza ndi kuwononga mphamvu ya chingwe cholumikizirana.

OPGW ndi yoyenera kugwiritsa ntchito mawaya amphamvu opitilira 110kv, ndipo mtunda ndi waukulu (nthawi zambiri umapitirira 250M); Yosavuta kusamalira, yosavuta kuthetsa vuto la kuwoloka kwa mzere, mawonekedwe ake amakaniko amatha kukwaniritsa kuwoloka kwa mzere; Gawo lakunja la OPGW ndi lachitsulo, lomwe silikhudza dzimbiri ndi kuwonongeka kwa magetsi amphamvu. OPGW iyenera kudulidwa panthawi yomanga, ndipo kutayika kwa magetsi kumakhala kwakukulu, kotero OPGW iyenera kugwiritsidwa ntchito pawaya atsopano amphamvu opitilira 110kv; Ulusiwu umapangidwa ndi ulusi wagalasi, womwe ndi wofooka komanso wofooka.

Pa nthawi yomanga, OPGW iyenera kutetezedwa kuti isakokedwe, kuphwanyika, kusweka, kuphwanyika, komanso chingwe chiyenera kukokedwa bwino popanda kufinyidwa.

Mfundo Zowongolera Ubwino wa OPGW

1. Kuyimika chingwe cha OPGW kumafanana ndi chingwe chamagetsi, poyimika, chingwe choyambirira chotumizira magetsi chiyenera kukhala chozimitsidwa, choletsedwa chifukwa cha mphepo, mabingu, kuzizira ndi kutentha ndi zina zomwe zimakhala nyengo yovuta. Kutalika kwa chingwecho kuyenera kukhala pamwamba pa 0.5m.

2. Kapangidwe kake kayenera kupewa kusakanikirana kwa chingwe, kuti chisawononge chingwe chakunja. Kupindika kwamphamvu sikungakhale kochepera nthawi 40 kuposa kukula kwa chingwe, ndiko kuti, pomanga kuti zitsimikizire kuti pali utali wozungulira wa 600mm, chingwe cha OPGW sichingapotokedwe.

Antchito apadera adzapatsidwa ntchito yoyang'anira njira zazikulu zodutsa magalimoto, zingwe zolumikizirana, zingwe zamagetsi, ndi zina zotero. Chingwecho chiyenera kuyendetsedwa pamalo otetezeka kuti magalimoto asagunde kapena kugubuduza chingwecho, zomwe zingaike pachiwopsezo chitetezo cha chingwecho kapena cha ogwira ntchito.

3. Zofunikira pa mtunda wolowera pansi pa chingwe cha OPGW: malo opanda anthu, OPGW yasiya pansi pa mtunda woposa 3m; Misewu ya oyenda pansi ndi misewu yokhala ndi magalimoto ochepa, OPGW ili pamtunda woposa 5m kuchokera pansi; Misewu ikuluikulu ndi njanji, OPGW pamwamba pa nthaka ndi 7.5m.

4. Pa ntchito yomanga, samalani ndi chitetezo cha waya wakunja. Waya wachitsulo wakunja wophimbidwa ndi aluminiyamu kapena waya wa aluminiyamu ndiye wonyamula mphamvu yamagetsi yochulukirapo ndipo mphezi, monga kuvulala, zidzakhala ndi zoopsa kwa nthawi yayitali pamzere. Yang'anani pulley kuti muwone ngati pali ma burrs; Musataye kapena kugwetsa zingwe zowunikira; Gwiritsani ntchito chivundikiro cha rabara kuti muteteze pogwiritsa ntchito chonyamulira waya. Thireyi ya chingwe ya OPGW imayikidwa pa raki yolipira kapena galimoto ya thireyi ya chingwe yokhala ndi shaft yozungulira, ndipo mtunda pakati pa thireyi ya chingwe ndi pakati pa makina opanikizika uyenera kutsimikizika kuti ndi 5-8m.

5. Tsiku lililonse, muyenera kuonetsetsa kuti ntchito yomanga diski imodzi ya chingwe chowunikira yatha, ngati si usiku umodzi kapena nthawi yayitali, pogwiritsa ntchito chingwe cha nayiloni, chingwe cha OPGW chimangiriridwa pa pulley, kuti chingwe chowunikira chisasunthike komanso kuwonongeka kwa kutopa kwa malo olumikizirana ndi ulusi wa kuwala ndi pulley. Nthawi yomweyo, chingwe chokokera ndi chingwe chowunikira ziyenera kulumikizidwa kwakanthawi kumapeto kwa chokokera ndi kumapeto kwa mphamvu motsatana. Mlingo wopumula wa chingwe pakati pa malo olumikizirana ndi chingwe chowongolera ndi makina okakamiza ndi woyenera kuti muchepetse mphamvu ya makina okakamiza. Sizingakhale zofooka kwambiri, chingwe sichiyenera kupukuta pansi.
