Zvishandiso zvinodiwa pakuongorora kunaka kwesimba
Parizvino, makambani emagetsi ane zvakawanda uye zvakanyanya kuomesesa zvinodiwa pamhando yemagetsi.Iko kushandiswa kwemagetsi kuongororwa kwekuwedzera kwebhizinesi kana kuvakwa kweprojekiti kutsva hakuchisina kungoti simba remagetsi system uye kugadziridzwa kwesimba remagetsi ndezvesainzi uye zvine musoro.Kukanganisa kwesimba remagetsi kunoisa mberi zvimwe zvinodiwa zvekuongorora.Kuti ubatsire mabhizinesi kuti abudirire kupasa chikumbiro chezvirongwa zvitsva, iyo Power Quality Division yeZhejiang Hongyan Electric Co., Ltd inopa simba rekuongorora uye masevhisi ekuongorora emapurojekiti matsva, anosanganisira hombe njanji njanji, Kuita magetsi emhando yekuongorora. uye ongororo yezviteshi zvechitima, simbi mill yemagetsi choto mapurojekiti, mabhesi makuru ekugadzira bhizinesi, kugovera magetsi epaki pre-kuronga, zvivakwa zvekuvaka zvekutengesa, nezvimwewo, kuitira kuti matambudziko emhando yemagetsi agone kutungamirwa nesainzi mukutanga kweiyo purojekiti panzvimbo yekumirira kusvikira hutano hwemagetsi Mushure mekunge dambudziko rasimbiswa uye rine simba guru, matanho ekugadzirisa anotorwa.
Kuongororwa kwemhando yesimba kunosanganisira kuongororwa kwesimba remhando yezviratidzo zvakaita seharmonics, kushanduka kwemagetsi uye flicker, simba chinhu, uye matatu-chikamu kusaenzana nekuenzanisa, kuongorora, uye kuverenga kukanganisa kwemagetsi emagetsi mushandisi wesimba system pane yakajairika system. mapoinzi ekubatanidza., Chirevo chekuongorora chinogona kupihwa mukati memazuva gumi ekushanda kana zvinhu zvakwana.

Kuongorora zvirimo:
Tevedzera, ongorora, uye verenga mabatiro esimba remushandisi musimba remushandisi pane yakajairika mapoinzi ekubatanidza masisitimu, kusanganisira zviratidzo zvemhando yemagetsi senge harmonics, kushanduka kwevoltage uye flicker, simba chinhu, uye-nhatu-chikamu kusaenzana.

Zviyero zvinoenderana nekambani yedu
Iyo yekuongorora hwaro hwemhando yesimba mukuongorora uye kuverenga maitiro inotora yakabatana simba remhando yemhando zviyero zvekambani yedu uye indasitiri yemagetsi, kusanganisira:
"Simba Hunhu-Unobvumidzwa Kusagadzikana kweMatatu-chikamu Voltage" (GB/T15543-2008)
"Simba Hunhu - Voltage Fluctuation uye Flicker" (GB12326-2008)

Zvishandiso zvinofanirwa kupihwa nevashandisi (zvishandiso zvinopihwa kune simba system magetsi emhando yekuongorora yemapurojekiti matsva)
Bato rinosungisa rinofanirwa kupa ruzivo rwunotevera uye nekuisa chisimbiso chepamutemo
1. Hurongwa hwemashandisirwo emagetsi, mushumo wezvidzidzo zvinogoneka, uye dhizaini yedhizaini (kusanganisira dhayagiramu yekutanga yemagetsi system) yakagadzirwa neMagetsi Power Design Institute yakatenderwa nePower Supply Bureau.
2. Iyo yeruzhinji yekupinda nzvimbo system voltage, system pfupi-circuit huwandu, system protocol huwandu, uye system simba rekupa simba rinotenderwa nemagetsi ekupa bureau.
3. Transformer technical parameters (kugona, voltage reshiyo, wiring nzira, impedance voltage)
