Ngati mukufunikira kuyendetsa zingwe zamagetsi m'nyumba kapena nyumba, muyenera kusankha chingwe choyenera. Chimodzi mwazosankha ndi chingwe cha magetsi. Kuti muwone ngati zoterezi ndizoyenera, muyenera kudziwa momwe zilili.
Chingwe cha Vvg - ndi chiyani
Chingwe chokha ndichowongolera chapadera: otsogolera otsekera wina ndi mnzake ndikuzunguliridwa pachimake. Ma conductor amatchedwanso mitsempha. Chingwe chimatha kukhala ndi pakati kapena zingapo. Chipolopolo nthawi zina chimakhala ndi zida - zoteteza. Zomerazo zimatha kupangidwa ndi aluminiyamu kapena mkuwa. Pali mitundu yambiri yam chingwe yamagetsi. Kuti muwasiyanitse ndi mawonekedwe, chizindikiritso cha zilembo chimagwiritsidwa ntchito. Iliyonse ya izo ili ndi tanthauzo lake.
- A - wochititsa wapangidwa ndi aluminiyamu;
- B - chloride ya polyvinyl;
- G - kalata yoyamba ya mawu oti "maliseche", ikuwonetsa kusowa kwa zida.
Tsopano timvetsetsa zomwe zimapanga chingwe cha VVG. Popeza palibe chilembo "A" pachidule chake, otsogolera pano ndi amkuwa. Zilembo ziwirizi "B" ndi umboni kuti zomerazo ndi waya wonse umapangidwa ndi chloride cha polyvinyl. Kupezeka kwa chilembo "G" kumatanthauza kuti chingwe sichitetezedwa. Zikuwoneka motere.
Chingwe cha Power VVG - mawonekedwe azida
Tiyeni tidziwe kapangidwe ka chingwe cha VVG, komanso mawonekedwe ake. Monga mukuwonera pachithunzichi, pamakhala zingwe zokhala ndi chingwe. Chithunzichi chikuwonetsa miyala iwiri - yoyera komanso yamtambo. Koma chingwechi chimatha kukhala ndi ma cores asanu. Zosankha zamtundu umodzi zimapezekanso. Ngati othandizira angapo, amapaka utoto wosiyanasiyana. Ma zingwe zamphamvu za VVG, monga lamulo, mtengo wotsatira umapita:
- wachikasu ndi mikwingwirima yobiriwira - kuyika;
- buluu wokhala ndi mzere Woyera - wozungulira zero;
- mitundu ina ndi gawo.
Kupatukana ndi mtundu wa chingwe VVG potengera mawonekedwe a ziwonetserozo. Zitha kupangidwa monga zigawo kapena mabwalo. Monga lamulo, pali owongolera angapo mu zingwe zomwe zili ndi magawo, ndipo ngati zinkakhala mozungulira, ndiye kuti nthawi zambiri chimakhala chimodzi.
Ngati tilingalira kusintha kwa chingwecho, kumatha kukhala kosalala kapena kozungulira, komanso mwanjira yamakona atatu kapena pentagon. Zimatengera kuchuluka komwe adakhalamo komanso ngati ndi apakatikati kapena ozungulira.
Mitundu ya chingwe cha VVG
Vvg ndichidule cha chingwe wamba, koma chimatha kusinthidwa. Izi zikuwonekera pakuphatikizanso kwa zilembo zowonjezera. Mwachitsanzo, kuphatikiza kwa "ng" kumatanthauza kuti mtundu uwu wa chingwe ndiosagwirizana. Amagwiritsidwa ntchito kwambiri muzipinda zomwe zimakhala ndi zowopsa zamoto. Ngati zilembo zimangowonjezeredwa ku chizindikiritso cha VVGG, chingwe chimakhala ndi zosiyana zotsatirazi:
- HF - chipolopolo chopangidwa ndi pulasitiki, momwe kuphatikizira kwa chlorine kumachepetsedwa. Chifukwa chake, utsi womwe umapezeka mkati mwazinthu zamafuta umakhala wopanda poizoni. Chifukwa chake, chingwe chotere chikalowa pamoto, sichingavulaze.
- LSLTx - kutchingira kwa oyendetsa ndipo chingwe chonsecho ndichopangidwa ndi pulasitiki, chomwe sichiwotcha ndipo sichipanga utsi. Ngakhale utsi ulipo mpaka pamlingo wocheperako, ulibe vuto lililonse kuz chilengedwe. Chingwe cha mtundu wamtunduwu VVG imagwira ntchito ngakhale moto. Kugwiritsa ntchito kwake: Mizere ya AC (voliyumu - osati kuposa 1000 V) kapena DC (voliyumu - osati kuposa 1500 V). Amagwiritsidwa ntchito polemba m'mabungwe azachuma.
- FRLS - otsogolera ali ndi njira yowonjezera yotetezera: matepi awiri, omwe amaphatikizapo mica. Chifukwa cha izi, chingwe ndichodalirika kwambiri, chifukwa chake chimagwiritsidwa ntchito pomwe pali chiwopsezo chowonjezereka cha kuphulika.
- LS - kutchingira kumapangidwa ndi chinthu chomwe chimatulutsa pafupifupi utsi nthawi zonse.
Waya yamagetsi ikasinthidwa m'nyumba, njira imodzi kapena yamagulu imachitidwa. Ngati tilingalira makamaka chingwe cha VVG yamagetsi, ndibwino kuti chizigwiritsa ntchito kukhazikitsa kamodzi. Pankhaniyi, ilinso kuti siyimayaka. Zofunika! Gulu likufunika, apa ayenera kuyika chimodzi mwazosintha za VVGG. Ndi iti - zimatengera muyeso wamoto wowopsa m'chipindacho.
Chingwe cha VVG - mawonekedwe
Kuti mugwiritse ntchito waya muzochitika zina, muyenera kudziwa momwe mulili. Makhalidwe a chingwe champhamvu cha VVG ndi awa:
- Kutentha kocheperako ndi 15 ° chisanu. Ngati kutentha kumakhala kotsika, muyenera kutentha. Koma ndibwino osachita izi, chifukwa njirayi ndi yovuta. Popanda kuyatsa kutentha pang'ono, chingwe chimakhala chokhazikika, kotero sichimangokhala.
- Kutentha kosavuta komwe waya ungagwiritsidwe ntchito kuyambira pa 50 ° chisanu mpaka kutentha kwa 50 °.
- Ma conductor amaloledwa kutentha mpaka 70 ° kutentha. Munjira izi, amatha kugwira ntchito kwa nthawi yayitali. Ndizotheka kuti kutentha kumakwera mpaka madigiri 90, koma izi ndizochepa. Njira iyi imaganiziridwa kuti ndi yadzidzidzi. Pakadutsa kanthawi kochepa, mitundu ina ya chingwe cha VVG imapitilizabe kugwira ntchito nthawi zonse pamene ziphuphuzi zimatenthedwa mpaka 250 °.
- Moyo wautumiki ndi zaka 30, chitsimikiziro cha zaka 5 chimaperekedwa.
- Nthawi yotsutsa moto pang'ono ndi maola atatu.
- Chingwe chaching'ono kwambiri chokhotakhota pakuyika: chingwe cha chimake chimodzi - kangapo m'mimba mwake cha gawo lake la mtanda, ma kiyimidwe ambiri - 7.5 diameter.
- Main voltage - 660 V, 1000 V.
- Mtengo wama pafupipafupi ndi 50 Hz.
Popeza chingwe cha VVG chimapangidwa ndi opanga osiyanasiyana, mawonekedwe awa amatha kusiyanasiyana pang'ono.
Chingwe chovomerezeka chopitilira chingwe cha VVG
Chingwe chilichonse chimakhala ndi mtengo wamagetsi wamtengo wapatali womwe umatha kugwira bwino ntchito. Nthawi yomweyo, matenthedwe ake sadzaposa pazotheka. Mtengo wake ndi wosintha, chifukwa zimatengera magawo angapo. Zazikulu zazikulu ndi kukula kwa gawo la wochititsa ndi kuchuluka kwa ziwongola zingwe mu chingwe.
Komanso, mtengo wa chovomerezeka chazitali wa VVG umawerengeredwa potengera momwe waya adzaikidwire - mlengalenga kapena pansi.
Chingwe chamtunduwu ndi bwino kuti chisayikidwe pansi, chifukwa mtolo wake sunatetezedwe.
Ngati pakufunikira izi, muyenera kuyikapo chingwe mu chitoliro kapena cholembera. Nawa ziwerengero zina zovomerezeka zamitundu yosiyanasiyana yamagetsi.
Kodi chingwe cha vvg chimagwiritsidwa ntchito bwanji ndipo
Chingwechi chimagwira bwino ntchito mzipinda zokhala ndi chinyezi chachikulu, chimalimba ngakhale 98%. Ndikofunika kuyiyika pazifukwa zosapsa: konkriti, njerwa, mapanelo a gypsum. Komanso, zitsulo ziyenera kukhala monga kupatula kuthekera kwa mawaya kupanga mawaya. Komabe, chingwe champhamvu cha VVG chitha kuyikidwanso m'njira yopingasa. Ndikofunikira kuti zitsimikizire kuti imatha kudalirika.
Chingwecho ndi choyenera kuzingidwa mumtundu uliwonse wamnyumba yanyumba. Zowona, m'nyumba zamatabwa njira yapadera ifunikira. Nazi mfundo ziwiri zofunika kuzikumbukira: sankhani chimodzi mwazitsulo za VVG yosagwirizana, ndikuyiyika mu chingwe chapadera chotetezedwa ku moto. Muthanso kugwiritsa ntchito malata achitsulo.
Chingwechi ndi choyeneranso kupanga mbewu. Amagwiritsidwa ntchito pamafuta amagetsi, ngakhale a nyukiliya. Ndi iyo, mawayilesi amapangidwa muzokongoletsera zowunikira, migodi, osonkhetsa, njira, makatani. Chingwecho chimakhala ndi machitidwe abwino komanso mtengo wotsika bwino, kotero chimagwiritsidwa ntchito kwambiri ndi anthu, pamenepo komanso pakupanga.
