Cable kuvaka zvinodiwa
Usati waisa tambo, tarisa kana tambo ine kukuvara kwemuchina uye kana tambo reel yakamira.Kune tambo dze3kV uye pamusoro, bvunzo yekumira yemagetsi inofanirwa kuitwa.Kune tambo dziri pasi pe1kV, 1kV megohmmeterinogona kushandiswa kuyera kudzivirira kwekudzivirira.Iko kukosha kwekudzivirira kwekudzivirira kazhinji haisi pasi pe10MΩ.
Usati watanga basa rekuchera mugero wetambo, mapaipi epasi pevhu, kunaka kwevhu uye nzvimbo yenzvimbo yekuvaka inofanira kunzwisiswa zvakajeka.Paunenge uchichera migero munzvimbo dzine mapaipi epasi pevhu, matanho anofanirwa kutorwa kudzivirira kukanganisa kune mapaipi.Pakuchera migero pedyo nematanda kana zvivakwa, matanho anofanirwa kutorwa kudzivirira kudonha.
Huyero yetambo yekubhenda radius kune tambo yekunze dhayamita haifanire kunge iri pasi pezvinotevera zvakatsanangurwa kukosha:
Kune mapepa-insulated akawanda-core magetsi tambo, iyo inotungamira sheath ka15 uye iyo aluminium sheath ka25.
Kune mapepa-insulated single-core power cables, iyo inotungamira sheath uye aluminium sheath zvese ka25.
Kune mapepa-insulated control cables, iyo inotungamira sheath ka10 uye aluminium sheath ka15.
Kune rabha kana epurasitiki insulated multi-musimboti kana single-core tambo, armored tambo iri kagumi, uye isina armored tambo ka6.
Kune chikamu chakatwasuka chetambo yakavigwa yakananga, kana pasina chivakwa chechigarire, masiteki emakaki anofanirwa kuvigwa, uye matanda emakaki anofanirawo kuvigwa pamajoini nemakona.
Kana iyo 10kV oiri-yakamisikidzwa bepa insulated simba tambo inovakwa pasi pemamiriro ekunze tembiricha pazasi 0.℃, iyo nzira yekudziya inofanira kushandiswa kuwedzera ambient tembiricha kana kupisa tambo nekupfuura ikozvino.Paunenge uchipisa nekupfuura ikozvino, kukosha kwazvino hakufanirwe kudarika iyo yakatemerwa ikozvino kukosha inobvumidzwa netambo, uye tembiricha yepamusoro yetambo haifanire kudarika 35.℃.
Kana kureba kwetambo yetambo isingapfuuri kureba kwekugadzira kwemugadziri, tambo yese inofanira kushandiswa uye majoini anofanirwa kudziviswa zvakanyanya sezvinobvira.Kana majoini achidikanwa, anofanirwa kunge ari pagomba remugero kana mubato wetambo mugero kana tambo tunnel, uye yakanyatso cherechedzwa.
Makombora akavigwa zvakananga pasi pevhu anofanirwa kuchengetedzwa nechombo uye anti-corrosion layer.
Kune tambo dzakavigwa zvakananga pasi pevhu, pasi pemugero unofanirwa kupepetwa uye kuumbwa usati wavigwa.Nzvimbo yakatenderedza tambo inofanira kuzadzwa ne100mm gobvu ivhu rakanaka kana rakarasika.Ivhu revhu rinofanira kuvharwa nekavha yakagadziriswa yekrete, uye majoini epakati anofanira kuchengetedzwa nejasi rekrete.Makombora haafaniri kuvigwa muzvikamu zvevhu nemarara.
Hudzamu hwetambo dzakavigwa dzakananga dze10kV uye pazasi kazhinji hadzisi pasi pe0.7m, uye kwete isingasviki 1m mumapurazi.
Matambo akaiswa mumatanho etambo uye tunnels anofanirwa kucherechedzwa nezviratidzo kune inotungamira-kunze kumigumo, zviteshi, majoini epakati uye nzvimbo dzinochinja nzira, zvichiratidza tambo yakatarwa, modhi, maseketi uye mashandisirwo ekugadzirisa.Kana tambo ichipinda mumugero wemukati kana duct, iyo anti-corrosion layer inofanira kubviswa (kunze kwekudzivirira kwepombi) uye pendi yekudzivirira ngura inofanira kuiswa.
Kana tambo dzichiiswa mumatombo epombi ekongiri, maburi anofanira kuiswa.Nhambwe iri pakati pemigodhi haifanire kunge yakakura kudarika 50m.
Manhole anofanirwa kuisirwa mumigero ine mabhenji, matavi, matsime emvura, nenzvimbo dzine misiyano mikuru mukukwirira kwenzvimbo.Nhambwe iri pakati pemigodhi muzvikamu zvakatwasuka haifanire kudarika 150m.
Pamusoro pemabhokisi ekuchengetedza kongiri akasimbiswa, pombi dzekongiri kana pombi dzakaoma dzepurasitiki dzinogona kushandiswa sepakati tambo majoini.
Kana kureba kwetambo inopfuura nemuchubhu yekudzivirira isingasviki 30m, iyo dhayamita yemukati yechikamu chakatwasuka chekudzivirira chubhu haifanirwe kunge isingasviki 1.5 nguva yekunze dhayamita yetambo, isingasviki 2.0 nguva kana paine bend imwe, uye kwete pasi pe2.5 nguva apo pane mabhendi maviri.Kana kureba kwetambo inopfuura nepakati pechubhu inodzivirira inopfuura 30m (inogumira kune zvikamu zvakananga), iyo dhayamita yemukati yechubhu inodzivirira inofanira kunge isingasviki 2.5 nguva yekunze kwetambo.
Kubatana kwetambo dzepakati waya dzinofanira kuitwa nerunyoro rwekutenderera.Mhangura dzemhangura dzinofanirwa kuve dzakashomerwa kana kuti welded nemaoko emhangura, uye maaruminiyamu macores anofanirwa kuvezwa nearuminiyamu maoko.Copper-aluminium transition yekubatanidza machubhu inofanira kushandiswa kubatanidza tambo dzemhangura nealuminium.
Ese aluminium musimboti tambo akaremerwa, uye iyo oxide firimu inofanira kubviswa isati yaita crimping.Iyo yakazara chimiro cheiyo sleeve mushure mekukwenya haifanirwe kuve yakaremara kana kukotama.
Tambo dzese dzakavigwa pasi pevhu dzinofanirwa kuongororwa mabasa akavanzika asati adzoreredzwa, uye dhirowa rekupedzisa rinofanirwa kudhirowa kuratidza iwo chaiwo marongero, nzvimbo uye gwara.
Kubatiswa kwesimbi dzisina ferrous uye zvisimbiso zvesimbi (zvinowanzozivikanwa sekuiswa chisimbiso chekutungamirira) kunofanira kunge kwakasimba.
Pakuisa tambo yekunze, kana uchipfuura nepaburi reruoko rwetambo kana mugodhi, tambo yega yega inofanirwa kucherechedzwa nechiratidzo chepurasitiki, uye chinangwa, nzira, tambo yakatarwa uye zuva rekuisa tambo rinofanira kunyorwa nependi.
Kune ekunze tambo yakavanzwa yekuisa mapurojekiti, kupedzisa kudhirowa kunofanirwa kupihwa kune inoshanda unit yekuchengetedza uye manejimendi zvinangwa kana chirongwa chapedzwa uye chaunzwa kuti chigamuchirwe.
