Dab tsi yog qhov cuam tshuam ntawm kev ua kom muaj roj ntau dhau ntawm cov hloov pauv tam sim no?
Sep 15, 2025| 1. Kev ntsuas thiab ntsuas qhov tsis raug
1. Nce cov kev piv txwv tam sim no
Tshaj dhau qhov ntsuas cov kev thauj khoom thib ob tuaj yeem ua rau cov kev ua yuam kev tam sim no, thiab ua rau muaj qhov ua yuam kev ntev (piv txwv li qhov yuam kev rau qib 0.5 tuaj yeem nce ntau tshaj 2%).
THEEM Yuam Kev Ntxiv nce ntxiv, cuam tshuam rau kev ntsuas hluav taws xob qhov tseeb (Cosrau yuam kev tuaj yeem tshaj 0.1).
2. Zog hluav taws xob nruj distortion
Kev yuam kev nce ntau ntawm cov khoom siv qis (piv txwv li, qhov yuam kev yuav ncav cuag 1.8% ntawm 20% ntawm rated tam sim no).
Kev yuam kev ntxiv ntawm cov chaw phem hauv cov neeg ua phem (qhov yuam kev ob npaug thaum cov ntsiab lus thib peb ntau dua 15%).
2. Tiv thaiv tsis ua haujlwm
1. Relay tiv thaiv tsis zoo / tsis ua tiav
Cov kev tiv thaiv sib txawv vim yog tam sim no tsis txaus ntseeg (kev hloov pauv ntau tshaj 0.1) . 0.5 hauv)
Kev tiv thaiv dhau los yuav ua haujlwm tsis ua haujlwm vim yog kev lwj siab tam sim no (lub sijhawm ua haujlwm yuav txuas ntxiv los ntawm ntau dua 30%).
2. Kev ua txhaum kev txhaum
Qhov kev ntsuas hluav taws xob theem nrab hauv qab luv- Circuit Court tam sim no tej zaum yuav tshaj lub hauv caug voltage (piv txwv li siv lub cuab tam
III. Khoom Siv Kev Nyab Xeeb Kev Nyab Xeeb
1. Tshem nrawm rwb thaiv tsev laus
Cov tub ntxhais muaj ntau tshaj li 70 qib) yuav ua rau muaj cov khoom siv rwb thaiv tsev.
Oil-immersed CTs may experience excessive acetylene levels (>5μL/L).
2. Cov Khoom Siv Puas
Sib nqus senation yuav ua rau 50}}}}} 100Hz tsawg-zaus kev co, ua rau xoob xoob, ua rau muaj kev sib tw. Cov kev sib tw sib chwv hauv lub cev tsis zoo tuaj yeem ua rau arcing (kev pheej hmoo yog qhov tseem ceeb thaum sib chwv tau> 0.1ω).
