High voltage main circuit common scheme
1. Ambient tembiricha: kunonyanyisa +40 ℃, shoma-30 ℃;
2. Altitude:≤3000m
3. Mhepo inomhanya: About34m / s (≤700Pa);
4. Humidity: Avhareji yemazuva ese hunyoro hunyoro≤95%
Avhareji yehunyoro hwepakati pamwedzi≤90%
5. Shake-uchapupu: Level acceleration≤0.4m/s2; kukwirisa kwakatwasuka≤0.15m/s2;
6. Gradient yekuisa nzvimbo: ≤ 3 °.
7. Kuisa nharaunda: mhepo yakapoteredza haina kusvibiswa zviri pachena negasi rinoparadza kana kuti rinopisa, uye hapana kunzwa kwakasimba kwekuvhunduka.
8. Ndapota taurirana nekambani kana chigadzirwa chakatengwa chinopfuura pamusoro pezvakarongwa.

Chimiro chechimiro chebhokisi chakavharirwa chinogadzirwa nechaneli simbi uye angle simbi ine yakakwirira mechanical simba.iyo yakavharirwa yakagadzirwa nealuminium alloy plate ine nzvimbo yakatsetseka, yakanaka outline uye zvirinani anti corrosion performance, hwaro hwebhokisi muviri wakareba 300-600mm kupfuura pasi. Magonhi ese ebhokisi akavharirwa akavhurika kunze, uye kuvhura angle yakakura kudarika 90 ° uye yakagadzirirwa nemudziyo wenzvimbo, zvibato, gonhi rakavanda, pamwe chete nekiyi yakavakirwa-mukati ine mabasa ekudzivirira mvura, anti-blockage uye kudzivirira ngura.mabhokisi ezvitunha ndeechisimbiso chakakwana chekuba-uchapupu.kuvimbisa kushanda pasi peyakajairika ambient tembiricha yemhepo, tembiricha yemidziyo yese yemagetsi haigone kudarika tembiricha inobvumirwa, uye bhokisi rebhokisi rine mazaruro emhepo akakwana uye matanho ekudzivirira kupisa.bhokisi remutumbi weiyo prefabricated substation rakagadzirwa neakakosha grounding conductor, pane anopfuura 2 akagadzika ekubatanidza materminal akabatana kune networking network uye pane zviri pachena zvibodzwa zvepasi.the grounding terminal ndiyo bhaudhi yemhangura, iyo dhayamita isingasviki 12mm.iyo yekumisa conductor inogadzirwa kubva kumhangura strip, iyo density yazvino haina kukwira kupfuura 200A/㎜² uye chikamu chemuchinjiko chisiri pasi pe30㎜², uye inovimbiswa kuti hapana kuwedzeredza uye hapana chakaipa. mhedzisiro kune kuchengetedzwa kwezvinhu zvakatenderedza kana yakanyanya kupfupi dunhu ikozvino inopfuura.iyo inochinja uye inopisa kugadzikana ikozvino iyo yakakosha yekumisa conductor inoshingirira inofanira kusanganiswa neiyo yekumisa maitiro emagetsi emagetsi ekuparadzira mudziyo.
Transformer performance parameters
Kune 10kV yakafanogadzirirwa substation performance level yeS9, S10, S11 yakatevedzana mafuta-akanyudzwa transformer.
a.Iyo yakakwira-voltage tapping renji inogona kugadzirwa kusvika ± 2 × 2.5% zvinoenderana nezvinodiwa nemutengi.
b.Iyo yakaderera voltage yetransformer inogona kugadzirwa kusvika 0.69kV zvinoenderana nezvinodiwa nemutengi.
