Q: Yog tias purity poob rau 95% vim huab cua nkag mus, GIS puas tseem ua haujlwm?
A: Nws yuav nyob twj ywm, tab sis kev nyab xeeb margins (arc quenching thiab txias) yog txaus ntshai txo.
Risks ntawm Low Purity:
❶ Txo Arc Quenching: Cua yog 100x phem dua SF6 thaum nres arcs. CB yuav tsis cuam tshuam.
❷ Thaum tshav kub kub Dissipation: Cov pa paug hloov pauv roj ceev thiab muaj peev xwm ua kom txias, ua rau kub dhau.
Cov qauv (IEC 60480):
• Gas Tshiab: Ntau dua lossis sib npaug li 99.9%.
• Ua pa roj: yuav tsum> 97%. Hauv qab 95% yuav tsum tau reclamation.
Peb txhais li cas SO2 thiab HF qib?
Q: Analyzer qhia 5 ppm ntawm SO2. Qhov tshwm sim li qub lossis kev ua txhaum sab hauv?
A: SO2 yog "Smoke Alarm" rau sab hauv arcing. Txhais raws li nram no:
|
SO2 Level |
Txhais lus |
Kev ua |
|
< 1 ppm |
Kev ua haujlwm li qub. |
Kev saib xyuas niaj hnub. |
|
1-5 ppm |
Me PD lossis hnyav hloov. |
Txo lub sijhawm xeem. |
|
5-10 ppm |
Ib qho teeb meem loj tshwm sim. |
Tshawb xyuas siv UHF / Acoustic PD. |
|
>10 ppm |
Kev puas tsuaj loj heev. |
Kev tshuaj xyuas tam sim/purification. |
Cov Lus Qhia Tshwj Xeeb: Yog tias ob qho tib si SO2 thiab HF siab, koj muaj ACTIVE tsis xws luag tsim cov kua qaub tam sim no.
