Kev Piav Qhia Txog Cov Ntsiab Lus Electromagnetic Hauv Kev Ua Haujlwm Transformer

1. ​Kev Ntsuas Lus​
   Lub Koom Haum Kev Noj Qab Haus Huv Ntiaj Teb (WHO) thiab Pawg Neeg Saib Xyuas Kev Tiv Thaiv Hluav Taws Xob Tsis-Ionizing (ICNIRP) cais qhov txawv ntawm "cov teb hluav taws xob" (qis dua 100 kHz) thiab "hluav taws xob hluav taws xob" (saum toj no 100 kHz). Cov chaw xa hluav taws xob tsim50Hz fais fab zaus electromagnetic teb, tsis yog hluav taws xob hluav taws xob. Qhov sib txawv tseem ceeb:

• Kev tawg hluav taws xobKev nthuav dav zog los ntawm cov nthwv dej electromagnetic (piv txwv li, cov nthwv dej xov tooj cua, X-rays)
• Cov teb zaus fais fab: Cov teb zoo li qub los ntawm kev siv hluav taws xob tsis muaj nthwv dej nthuav dav

2.​Cov Yam Ntxim Saib Xyuas​
Cov teb transformer muaj cov yam ntxwv tshwj xeeb:

• Zaus: 50Hz (nthwv dej 6,000km)
• Kev puas tsuaj ntawm thaj chaw: Qhov muaj zog ntawm thaj chaw sib nqus txo qis los ntawm 1 / d² (d = nrug)
• Kev Tiv Thaiv: Cov hlau thaiv txo cov teb los ntawm >90%
• Cov ntaub ntawv ntsuas:

(Cov ntaub ntawv los ntawm cov ntawv ceeb toom saib xyuas grid

3.​Kev Ntsuas Kev Nyab Xeeb​
Kev tshuaj xyuas sib piv qhia tau tias:

• Cov teb transformer: 0.1-1% ntawm ICNIRP txwv (5kV/m E-field, 100μT B-field)
• Cov khoom siv hauv tsev: Lub qhov cub microwave (1793V/m), lub tshuab ziab plaub hau (600V/m)
• Kev nyab xeeb txwv: 10,000μT rau cov teebmeem tsis zoo tam sim ntawd (WHO)

4. Kev Pom Zoo Txog Kev Noj Qab Haus Huv​
Kev tshuaj xyuas cov ntaub ntawv ntawm 30+ xyoo lees paub tias:

• Tsis muaj kev sib raug zoo ntawm 50Hz teb thiab mob qog noj ntshav / mob plawv
• Cov tsos mob ib ntus (mob taub hau/qaug zog) tsuas yog tshwm sim >8 teev/hnub raug rau >100μT teb
• Kev nyab xeeb hauv kev ua haujlwm: Cov neeg ua haujlwm hauv Grid raug kev txom nyem txhua hnub tsis qhia txog cov qauv kev noj qab haus huv tsis zoo

5.​Cov Tswv Yim Txo Kev Txo Nqi​
Cov lus qhia kom ceev faj:

• Tswj kom deb li ntawm 1.5m ntawm 10kV transformers
• Siv cov hlau thaiv av rau kev teeb tsa sab nraum zoov
• Nruab cov khoom thaiv kev tiv thaiv (> 3 hli txhuas sib npaug) rau cov chaw rhiab heev

Qhov kev piav qhia txog kev siv tshuab no sib haum nrog cov qauv thoob ntiaj teb thiab kev ntsuas qhov tseeb, qhia tau tias cov teb hluav taws xob transformer tseem nyob hauv cov kev ua haujlwm nyab xeeb.
