Cov khoom tseem ceeb thib ob feem ntau siv hauv lub txee (tseem hu ua cov khoom siv thib ob lossis cov cuab yeej pabcuam, xa mus rau cov khoom siv hluav taws xob qis uas saib xyuas, tswj, ntsuas, kho thiab tiv thaiv cov khoom siv thawj zaug), cov khoom siv feem ntau yog cov khoom siv hauv qab no:
1.Relay 2. Hluav taws xob ntsuas 3. Ammeter 4. Voltage meter 5. Fais fab meter 6. Fais fab meter 7. Zaus meter 8. Fuse 9. Cua hloov 10. Hloov-over switch 11. teeb liab teeb 12. Resistance 13. Button 14. Microcomputer integrated tiv thaiv ntaus ntawv thiab hais txog.
2. Kev faib tawm ntawm high voltage hloov khoom:
2.1. Raws li txoj kev teeb tsa ntawm lub Circuit Court breaker, nws tau muab faib ua hom tshem tau (lub tawb nqa khoom) thiab hom ruaj khov
(1) Tshem tawm los yog lub tawb nqa khoom (qhia los ntawm Y): Nws txhais tau hais tias cov khoom siv hluav taws xob tseem ceeb (xws li cov hluav taws xob hluav taws xob) hauv lub txee tau nruab rau ntawm lub tawb nqa khoom uas tuaj yeem thim tau, vim tias cov khoom siv hauv lub tawb nqa tau zoo sib hloov yog li ntawd, nws tuaj yeem ua tau. zoo heev txhim kho kev ntseeg tau ntawm lub hwj chim mov. Feem ntau siv hom tsheb thauj khoom yog: cov tsheb sib cais, cov tsheb thauj khoom siv hluav taws xob, cov tsheb thauj khoom siv hluav taws xob, PT handcarts, capacitor handcarts thiab handcarts siv, xws li KYN28A-12.
(2) Kho hom (qhia los ntawm G): Qhia tias tag nrho cov khoom siv hluav taws xob (xws li cov khoom siv hluav taws xob lossis cov khoom siv thauj khoom, thiab lwm yam) nyob rau hauv lub txee yog ruaj khov, thiab cov txee hloov ruaj khov yog qhov yooj yim thiab kev lag luam, xws li XGN2-10 , GG-1A thiab lwm yam.
