Momwe mungaletsere dzimbiri lamagetsi la ADSS Optical cable?
Monga momwe tikudziwira, zolakwika zonse zamagetsi zamagetsi zimachitika m'dera logwira ntchito, kotero kuti mtunda woti uwongoleredwe umayikidwanso muzoni yogwira ntchito.
1. static control:
Pansi pazikhalidwe zosasunthika, kwa chingwe cha AT sheathed ADSS chogwira ntchito mu dongosolo la 220KV, kuthekera kwapang'onopang'ono kwa malo ake olendewera kuyenera kuwongoleredwa osapitilira 20KV (mizere yamagawo awiri ndi ma circuit co-frame iyenera kukhala yotsika);kugwira ntchito mu 110KV ndi pansi machitidwe Kwa PE sheathed ADSS optical chingwe, kuthekera kwa malo a popachikidwa kuyenera kuyendetsedwa kuti ikhale yosakwana 8KV.Kuthekera kwa malo a malo olendewera static ayenera kuganizira:
(1) Mphamvu yamagetsi ndi dongosolo la gawo (malupu awiri ndi malupu angapo ndizofunikira kwambiri).
(2) Maonekedwe a mtengo ndi nsanja (kuphatikiza mutu wa nsanja ndi kutalika kwadzina).
(3) Kutalika kwa chingwe cha insulator (kutalika kwake kumasiyana malinga ndi mlingo wa kuipitsidwa).
(4) M'mimba mwake wa kondakitala / waya pansi ndi kugawanika kwa kondakitala.
(5) Mtunda wachitetezo pakati pa waya ndi nthaka ndi zinthu zodutsa.
(6) Kuwongoka / sag / span control (popanda mphepo, palibe ayezi, ndi kutentha kwapakati pachaka, katunduyo si wamkulu kuposa ES wa chingwe cha kuwala, chomwe ndi 25% RTS; pansi pa mapangidwe a nyengo, katunduyo si wokwanira. chachikulu kuposa chingwe cha kuwala The MAT ndi 40% RTS).
(7) Zodumpha (zitsulo zomangika) ndi matupi apansi (monga zingwe zazitsulo za simenti) ziyenera kuwerengedwa ndipo mphamvu zawo ziyenera kuganiziridwa.
2.dynamic control:
Pansi pa zochitika zamphamvu, mphamvu ya danga la AT sheathed ADSS Optical cable yomwe ikugwira ntchito mu 220KV system iyenera kuyendetsedwa kuti isapitirire 25KV;PE sheathed ADSS kuwala chingwe ntchito mu dongosolo la 110KV ndi pansipa, kuthekera danga la popachikidwa kuyenera kukhala Control izo zosaposa 12KV.Mphamvu zamphamvu ziyenera kuganizira:
(1) Mphamvu yamagetsi ndi mphamvu yamagetsi, ndipo nthawi zina padzakhala cholakwika cha +/- (10 ~ 15)%, ndipo kulolerana kwabwino kudzatengedwa;
(2) Chingwe chazitsulo (makamaka chingwe cholendewera) ndi mphepo yamkuntho ya chingwe cha kuwala;
(3) Kuthekera kwa kusintha kwa gawo loyambirira;
(4) Kuthekera kwa ntchito imodzi-yozungulira yapawiri-circuit system;
(5) Mkhalidwe weniweni wa kusamutsa kuipitsa m'dera;
(6) Pakhoza kukhala mizere yatsopano ya crossover ndi zinthu;
(7) Mkhalidwe wa zomangamanga zamatauni ndi mapulani achitukuko panjira (zitha kukweza pansi);
(8) Zinthu zina zomwe zingakhudze chingwe cha kuwala.
Amakumbutsa kuti izi ziyenera kutsatiridwa pakumanga mawaya a ADSS optical cable.
(1) Kuwonongeka kwamagetsi kwa ADSS kuwala kwa chingwe m'chimake pansi pa zovuta pakugwira ntchito kumayambitsidwa ndi kutayikira kwapansi kwaposachedwa kwa pafupifupi 0.5-5mA ndi gulu louma la arc chifukwa cha kuthekera kwa danga (kapena mphamvu yamagetsi yamagetsi) kudzera pa kulumikizana kwa capacitive.Ngati njira zowongolera kutayikira kwa nthaka pansi pa 0.3mA ndipo arc yosalekeza siipangidwa, dzimbiri lamagetsi la sheath silingachitike.Njira yowona komanso yothandiza kwambiri ndikuwongolera kupsinjika ndi kuthekera kwapang'onopang'ono kwa chingwe cha kuwala.
(2) Malo osasunthika omwe amatha kupanga a AT kapena PE sheathed ADSS Optical cable sayenera kupitilira 20KV kapena 8KV, motsatana, ndipo sayenera kupitilira 25KV kapena 12KV pansi pazovuta kwambiri.Chingwe cha fiber optic chikhoza kuyendetsedwa bwino.
(3) The malo amodzi kuthekera danga ndi 20KV (makamaka 220KV dongosolo) kapena 8KV (makamaka 110KV dongosolo).The odana ndi kugwedera chikwapu kulekana hardware mu dongosolo si osachepera (1 ~ 3) m kapena 0.5m, motero, kukonza ADSS Imodzi mwa njira zothandiza kwa dzimbiri magetsi zingwe kuwala.Panthawi imodzimodziyo, kuwonongeka kwa kugwedezeka kwa chingwe cha ADSS ndi njira zina zotsutsana ndi kugwedezeka (monga nyundo yogwiritsira ntchito anti-vibration) ziyenera kuwerengedwa.
(4) Kuyika kwa chingwe cha kuwala (komwe nthawi zambiri kumatchedwa popachika) sikungadziwike mwamphamvu potengera mlingo wamagetsi a dongosolo ndi / kapena mtunda kuchokera kwa woyendetsa gawo.Kuthekera kwa danga la malo opachika kuyenera kuwerengedwa molingana ndi mikhalidwe yamtundu uliwonse wa nsanja.
(5) Ngakhale kuti nthawi zambiri pakhala kulephera kwamagetsi kwamagetsi a ADSS optical cables m'zaka zaposachedwa, machitidwe ambiri atsimikizira kuti zingwe za ADSS Optical zikhoza kupitiriza kulimbikitsidwa ndikugwiritsidwa ntchito mu machitidwe a 110KV;Zingwe zamagetsi za ADSS zomwe zimagwiritsidwa ntchito m'makina a 220KV zimatengera zonse zomwe zikuchitika komanso momwe zimagwirira ntchito.Pambuyo pake, mutha kupitiliza kulimbikitsa pulogalamuyi.
(6) Pamalo owonetsetsa kuti chingwe cha kuwala cha ADSS chili chabwino, kulinganiza kamangidwe kaumisiri, kamangidwe ndi kagwiritsidwe ntchito, komanso kuwonongeka kwamagetsi kwa chingwe cha ADSS chowongolera.Ndikofunikira kupanga ndikukhazikitsa zikhalidwe / njira zofananira mwachangu momwe zingathere.
