Dab tsi yog qhov Parameters ntawm Fais Fab Capacitor Nameplates sawv cev?

Rated Voltage (V): Ibyog qhov voltage (RMS) thov ntawm ob lub terminals ntawm lub capacitor thaum nws tsim. Rau hluav taws xob capacitors, chav tsev ntawm qhov ntsuas hluav taws xob feem ntau yog V, thaum lub hwj chim capacitor, nws feem ntau qhia hauv kV.

Rated tam sim no (A): Hauvyog alternating tam sim no (RMS) teev thaum lub sij hawm tsim ntawm lub capacitor, nrog rau chav tsev yog A.

Rated Peev xwm (kvar): Qnsawv cev rau reactive zog tso zis los ntawm lub capacitor nyob rau hauv rated voltage thiab zaus. Nws ua hauj lwm raws li tus nqi tsev rau lub hwj chim capacitors.

Rated Capacitance (μF): Cyog tus nqi capacitance tau txais thaum lub sij hawm tsim ntawm lub capacitor, qhia tias nws muaj peev xwm khaws cov nqi hluav taws xob (μF).

Rated Zaus (50/60 Hz): Fyog qhov kev khiav hauj lwm zaus uas lub capacitor tsim, muaj feem xyuam rau ob qho tib si -theem lossis peb-theem systems (3/1).

Chav ntsuas kub (degree):Feem ntau qhov ntsuas kub tsawg kawg nkaus suav nrog: +5 degree, -5 degree, -25 degree, -40 degree, thiab -50℃. Qhov ntsuas kub siab tshaj plaws suav nrog: +40℃(Class A), +45℃(Class B), +50℃(Class C), thiab +50℃(Class D), tag nrho plaub chav kawm.

Capacitance kam rau ua: For capacitor units and banks rated ≤100 kvar: -5% to +15%; for those rated >100 kvar: 0 rau +10%. Qhov siab tshaj plaws capacitance sib txawv ntawm cov theem sib txawv yuav tsum tsis pub tshaj 1.08.

Discharge Resistor:Rau qis-voltage capacitors, tom qab fais fab- tawm, qhov hluav taws xob yuav tsum poob ntawm √2Un mus rau qis dua 75V hauv 3 feeb. Rau siab-voltage capacitor, tom qab fais fab- tawm, qhov hluav taws xob yuav tsum poob ntawm √2Un mus rau qis dua 75V hauv 10 feeb.

Kev Ua Raws Cai:IEC 60831-1 / 60831-2 2014
