Tam sim no Transformer Secondary Overvoltage Protector
Scope ntawm daim ntawv thov
Tam sim no transformer theem nrab overvoltage protector yog tsim nyog rau txawv winding, overcurrent winding, ntsuas winding, tsheb npav tiv thaiv winding thiab thaub qab winding ntawm CT thib ob sab.Nws yog siv los txwv tsis pub dhau lub sijhawm dhau los hauv qab qhov cuam tshuam overvoltage ntawm cov khoom siv thiab tso tawm hluav taws xob hluav taws xob, txhawm rau tiv thaiv qhov system Circuit Court thiab khoom siv.
Cov xwm txheej zoo li qub thiab kev teeb tsa
1. Cov kev pabcuam ib txwm muaj
a.Voltage: Qhov hluav taws xob tsis tu ncua ntawm cov hluav taws xob tiv thaiv hluav taws xob yuav tsum tsis pub tshaj nws qhov siab tshaj plaws
Loj nruam kev khiav hauj lwm voltage.
b. Ambient kub: -20 ℃ ~ 70 ℃.
c. Ambient humidity siv: <95%RH.
d. Kev tiv thaiv tsev: IP20.
e.Pollution Level: Cov pa phem ntawm qhov chaw teeb tsa yog qib 2.
2. Kev teeb tsa kev teeb tsa
a.Installation qeb: raws li qhov voltage tiv thaiv qib ntawm overvoltage tiv thaiv ntaus ntawv muab faib ua ob pawg;
b.installation site:

1. Pom zoo rau qhov chaw tsis tshua pom;
2. Nws yuav tsum tau ntsia tsis muaj kev vibration tseem ceeb thiab cuam tshuam.
3. Txoj kev txhim kho: siv TH35-7.5 hom tsheb ciav hlau rau kev teeb tsa.
4. Hom kab hlau: ntsia hlau nias thaiv.
