Voltage Transformer Test Classification: Daim ntawv qhia ua tiav rau cov kws tsim hluav taws xob

Kev faib tawm ntawm Voltage Transformer Tests: -
Hom Kev Xeem: Cov nram qab no yuav tsim cov kev xeem hom:
a) Kev ntsuas kub nce
b) Lightning impulse test rau voltage transformers rau kev pab cuam nyob rau hauv hluav taws xob raug teeb tsa.
c) Hloov cov kev ntsuas hluav taws xob rau qhov ntsuas hluav taws xob ntawm 420 kV thiab siab dua
d) High voltage fais fab zaus ntub dej tiv thaiv qhov ntsuas hluav taws xob ntawm sab nraum zoov voltage transformers mus txog thiab suav nrog 245 kV
e) Kev txiav txim siab ntawm qhov yuam kev lossis lwm yam ntxwv raws li qhov yuav tsum tau ua ntawm cov qauv tsim nyog lossis cov chav kawm raug
Routine Tests: Cov nram qab no yuav tsum yog cov kev xeem niaj hnub
a) Kev txheeb xyuas cov cim davhlau ya nyob twg thiab polarity
b) Lub zog zaus qhuav tiv thaiv kev sim ntawm thawj windings
c) Fais fab zaus qhuav tiv thaiv cov kev sim ntawm cov windings thib ob
d) Kev ntsuas qhov tso tawm ib nrab raws li IS 11322: 1985.
e) Kev txiav txim siab ntawm qhov yuam kev lossis lwm yam ntxwv raws li qhov
cov kev xav tau ntawm cov npe tsim nyog lossis cov chav kawm raug
Optional Tests
Cov kev ntsuam xyuas hauv qab no, yog tias tsim nyog, yuav tsum tau ua los ntawm kev pom zoo
nruab nrab ntawm tus neeg yuav khoom thiab cov chaw tsim khoom:
a) Chopped teeb pom kev zoo impulse kuaj raws li hom kev sim
b) Short circuit withstand peev xwm test as a type test
c) Kev ntsuas kev ntsuas ntawm qhov tsis yog-earthed voltage transformers mus txog thiab suav nrog 36 kV.
