High-Precision Laboratory Standard Voltage Transformer Solution Gwaji Da Kyau A Matasa A Cikin Kayan Aiki Na Tsaroji Votaji

Ⅰ. Yakin Tsarin Kadan: Tashar da Maɓalluka ga Mauduɗi na Metroloji
Wannan haɗin kai yana ƙunshi tashar da maɓalluka ga IEE-Business wanda ke fitaccen cin gaba da cikin tashar da maɓalluka ga kasar, wanda ke amfani da zane da tsari mai zurfi don haka da magana da abubuwa masu matattaccen siyasa na International System of Units (SI). Wannan yana taimakawa wajen buɗa wasu abubuwa masu kudin da suka shafi muhimmiyar alama, ta haka ya bayar da iyaka mai karatu na voltaji na musamman da za su iya amfani da su a makarantun maye.

Ⅱ. Kasasheccen Yakin Kadan
Tsari mai Zabi Don Tabbatar da Abubuwa na Transformer
• Ya amfani da tsari mai biyu da zane da tsari mai zabi, wanda ke taimakawa wajen tabbatar da abubuwa masu transformer da zane da tsari mai zabi, ta haka ya taimakawa wajen rarrabta abubuwa masu transformer na farko daidai.
• Zaman lafiya na tsari mai zabi: ±0.5 ppm, wanda ke taimakawa wajen gyara abubuwa masu zabi a matsayin yanayin ɗaya (1%–120% Un).

• Sistem na Tabbata Tsakiyar Dukkuyi
  • Ana kafa da ruwan dukkuyi na synthetic ester (coefficient of thermal expansion <100 ppm/°C).
  • Sistem na tsaƙaƙar tsakiyar dukkuyi na uku:
  • Zaman lafiya na tsakiyar dukkuyi: 55±0.05°C (da ita ce ±0.1°C)
  • Tabbacin tsakiyar dukkuyi: <0.3°C a matsayin yanayin ɗaya a cikin tsari
  • Tsakiyar dukkuyi mai zaman lafiya: >8 awa; tushen ranar <0.01°C.
• Risistanci na Voltaji na Tabbaccewar TCR Da Ƙarshen Quartz
  • Ana kafa risistanci a ƙarshen quartz (CTE=0.55 ppm/°C).
  • Risistanci na metal thin-film (NiCrAl alloy) da ake gina da laser:
  • Tabbacin tsakiya (TCR): <0.05 ppm/°C (da ita ce a matsayin yanayin ɗaya)
  • Tabbacin voltaji (VCR): <0.02 ppm/V
  • Tushen shekarar: <3 ppm

Ⅲ. Wasu Masu Amfani Da Ita
• Standard na voltaji na institutun metroloji na kasar
• Noma na voltaji na tashar da maɓalluka na chip manufacturing (misali, etchers na 0.1nm-resolution)
• Tabbatar da iyaka na magnetic confinement power supplies a fusion devices
• Tabbatar da iyaka na resistivity measurements na novel semiconductor materials
