Mitemo Yepasi Pose yeVoltage & Gwaro Rekusarudza Sarudzo yeHigh Voltage Transformer

1. Kupatsanura Mavhiriji & Mabasa eTransformer​

 

Matransformer ane voltage yakakwira (HV) akagadzirwa kuti ashandise mavoltage ≥35 kV (North America) kana ≥36 kV (Europe), anonyanya kushandiswa mumanetwork ekutumira magetsi kuwedzera simba rinobuda mujenareta pakutumira magetsi kure uye kudzika voltage pazviteshi zvemagetsi. Kusiyana neizvi, matransformer ane voltage yakaderera (LV) (≤1 kV) anobata kugoverwa kwenzvimbo, achidzikisa voltage yegrid kusvika pamazinga anoshandiswa ekutakura magetsi ekugara, ekutengeserana, uye emaindasitiri. Matransformer ane simba anotungamira mashandisirwo eHV (semuenzaniso, 110–765 kV), ukuwo Transformer yekugoveras kutarisa pamasikiro eLV (≤33 kV).

 

2. Maitiro eMagetsi eDunhu uye Mashandisirwo​

 

China: Inoshandisa grid reUHV DC rakakura kupfuura mamwe ose pasi rose (±1100 kV) rekufambisa magetsi kumadokero-kumabvazuva. Matunhu ekumaruwa anoshandisa ma transformer e10 kV/0.4 kV pakuisa magetsi.

 

North America: Inoshandisa 138–765 kV pakufambisa magetsi. Mapurazi emhepo ekuTexas anoda ma transformer makuru ane simba re 345 kV step-up. Madhizaini e split-phase (240V center-tapped) ndiwo akajairika kuma residential circuits.

 

Europe: Inosimbisa magadzirirwo asingakuvadzi nharaunda, akadai se ester-Transformer yemafutas uye magrid akangwara (semuenzaniso, chirongwa cheE-Energy cheGermany). Mapurazi emhepo ari kunze kwegungwa muNorth Sea anoshandisa zviteshi zvemagetsi zve66–220 kV.

 

Japan: Ine ma transformer anodzivirira kudengenyeka kwenyika ane mabushing anochinjika uye masisitimu ekugara e100V akasiyana. Ma transformer ane mafrequency maviri (50/60 Hz) anodiwa kuti grid isanganiswe kumabvazuva-kumadokero.

 

India: Inosimudzira ma transformer asina chimiro kuti aderedze kurasikirwa ne70% uye inogadzirisa magetsi ekumaruwa ne 11 kV/230V systems.

 

3. Maitiro Ekusarudza Zvehunyanzvi​

 

Kufananidza Voltage: Iva nechokwadi chekuti ±0.5% hapana mutoro uye ±1% kutsungirira mutoro wakazara zvichienderana neIEC 60076. Masisitimu esimba rinodzokororwa (semuenzaniso, mapurazi ezuva) angada ±10% dynamic regulation.

 

Kugona & Mutoro: Shandisa fomura S=3×U×I kuti uverenge kVA. Chengetedza mutoro wenguva refu we60–80% kuti ushande zvakanaka. Mitoro inotarwa panguva dzakasiyana (semuenzaniso, simbi) inoda 115% yemutoro wekuwedzera kweawa imwe chete.

 

Kudzivirira & Kutonhodza:

 

Inonyudzwa muOiri: Inodhura zvishoma pamagetsi ekunze asi inoda masisitimu ekudzima moto.

 

Rudzi Rwakaoma (Resin): Haitsvi moto uye haigadziriswi zvakanyanya, yakakodzera zvivakwa asi inodhura ne30%.

 

SF₆ Gasi: Yakabatana uye haisvibisi kusvibiswa kwenzvimbo dzemagetsi mumaguta asi inotarisana nekuongororwa kwezvakatipoteredza.

 

Maitiro Ekushanda Nesimba:

 

Giredhi 1 reGB 20052 rekuChina rinoderedza kurasikirwa kwemotokari pasina mutoro ne40% zvichienzaniswa neGiredhi 3.

 

Mirairo yeEU Tier 3 ichabvisa mamodheru asina kushanda zvakanaka panosvika gore ra2025.

 

4. Dambudziko Nemhinduro Dzakajairika​

 

Kusarongeka: Kushandisa maLV transformers mumaHV grids kunokonzera kupisa zvakanyanya uye kutadza kupinza zvinhu. Batisisai zvakasimba 66 kV thresholds.

 

Kutevedzera Mutemo Wedunhu: Mitemo yekushanda zvakanaka yeDOE 2016 yeNorth America yakasiyana neEU's Ecodesign Tier 2. Kuongororwa kwevanhu vechitatu (semuenzaniso, mishumo yeCTI/STL) kunoita kuti pave nekutevedzera mitemo.

 

Kugadziriswa Kwezvakatipoteredza:

 

Kureba Kwakakwirira: Kukwanisa kwenzvimbo yacho kuderera ne5%/500m (semuenzaniso, mapurojekiti eAndes).

 

Kuora: Zvivharo zvesimbi isina ngura uye machira ane mativi matatu anoderedza kukuvara kwekupfapfaidza munyu.

 

5. Mafambiro Ari Kubuda​

 

Magridhi Akangwara: Masisitimu ekutarisa emuEurope panguva chaiyo uye kugadzirisa kwekufanotaura kunotungamirwa neAI zvinovandudza mashandiro etransformer.

 

Kubatanidzwa kweRenewables: Mapurazi emhepo ari kunze kwegungwa nezvirimwa zvezuva zvinoita kuti pave nekudiwa kwematransformer e35–132 kV ane simba rekubatana (K≥13).

 

Kugara kwenguva refu: Makori asina kusimba, mafuta e-ester anoora, uye zvinhu zvinogona kudzokororwa zvinochinja patsva magadzirirwo azvo.

 

Zvinhu Zvikuru Zvekudzidza

 

Kutarisa pakugadzira: Matransformer eHV anonyanya kukoshesa simba rekudzivirira kupisa uye kutonga kwekupisa, ukuwo matransformer eLV achisimbisa kuomarara uye kuchengetedzeka.

 

Kutevedzera Mutemo Wepasi Pose: Mitemo yakaita seIEC 60076 (HV) uye UL/CE (regional) inorayira kuyedzwa kwakasimba kwesimba remagetsi uye kugona kwezvakatipoteredza.

 

Mutengo wehupenyu: Mhando dzinoshanda zvakanyanya (semuenzaniso, dzisiri dzemhando yepamusoro) dzinopa mari inodzoserwa mumakore matatu kuburikidza nekuchengetedza simba, kunyangwe mitengo yakakwira yekutanga.

 

Kuti uwane mhinduro dzakagadzirirwa iwe, bvunza vatengesi vakaita seEnergy Transformer, iyo inopa kugadziriswa kwedata zvakananga kubva kufekitori uye zvitupa zvekutevedzera mitemo pasi rose.
