- Test lub hom phiaj:
- Qhov kev xeem no kuj suav hais tias yog ib qho ntawm cov kev xeem tseem ceeb thiab nws lub hom phiaj yog
mus kuaj:
• Voltage transformer piv.
• Voltage transformer polarity.
• Voltage transformer winding kuj.
• Megger test (cov rwb thaiv tsev).
- Cov khoom siv yuav tsum tau:
• FA-205B CT PT analyzer
• Multi-meter (Fluke).
- Mechanical checked thiab pom kev soj ntsuam:
• Tshawb xyuas qhov nruj ntawm kev sib txuas.
• Tshawb xyuas ferrules.
- Voltage transformer test kev twb kev txuas
Kev sib txuas hom yog raws li qhia hauv daim duab 11 (PT), luv luv Circuit Court sab ob 'a' thiab 'x' thiab txuas lawv mus rau qhov ntsuas hluav taws xob tso tawm qhov hluav taws xobK2, thaum lwm qhov voltage tso zis davhlau ya nyob twg ntawm lub testerK1 yog txuas nrog lub plhaub transformer.
txav tus maub los rauKuajkom nce qhov voltage thiab tswj nws rau 60s. Yog tias qhov tshwm sim flashover tshwm sim hauv qhov kev sim, ces CT thib ob rwb thaiv tsev tiv thaiv hauv av yog suav tias tsis tsim nyog. Yog tias qhov hluav taws xob xau siab dhau lawm, cov khoom siv yuav rov qab mus rau xoom rau kev tiv thaiv.
