HZYA-2Z Digital Transformer On Load Switch Tap-Changer Analyzer

HZYA-2Z Digital Transformer On Load Switch Tap-Changer Analyzer

I.Beskrivelse

The on-load tap-changer is the only moving part connected to the transformer circuit. Therefore, the detection of the on-load tap-changer is becoming more and more important. In the "power equipment transfer and preventive test procedures", asked to check the on-load tap-changer action sequence, measurement switching time. The instrument is mainly used to measure the transformer on-load tap-changer transition waveform, transition time, the instantaneous transition resistance, three-phase synchronization and so on.

Instrumentet er meget intelligent, alle kinesiske menu-prompter, enkel betjening. Instrument lille størrelse, let vægt, anti-interferens evne, i høj grad reducere arbejdsintensiteten af ​​webstedets personale, er strømforsyningsenheder, transformer fremstillingsindustrien for at sikre sikker produktion, forbedre produktkvalitet ideelle instrument.
