Barin tarka na insulation don GIS isolation switch na 252-1100kV shine component mai gaba a cikin gas insulated metal enclosed switchgear (GIS) na ultra-high voltage. Tsarin kayan aiki da muhimmanci a fannin aiki sun hada:
1、 Muhimmancin abubuwan rayuwar
Tsarin insulation na karamin kula
Yana bukata a duba karamin kula na power frequency na 252-1100kV (wanda ke shafi a yi test na power frequency withstand voltage na 1.1 × 1100kV/5-minute don 1100kV GIS) da lightning impulse voltage (1.1 × 2400kV)
Karamin partial discharge yana bukatar ≤ 1.5pC (a cikin yanayi na 1.2 × 635kV) don samun sabon aiki masu tsari
Tsarin mechanical
Tensile strength ≥ 300kN, mechanical life ≥ 10000 opening and closing operations, yana da kyau a kan high impact loads (misali 40kA short-circuit current breaking)
Dynamic response frequency ya kamata yake cikin 0-600Hz don tabbatar da resonance risk
2、 Samun ci gaban a matsayin da craftsmanship
Abubuwan kayan aiki masu muhimmanci
Epoxy glass cloth tube: an yi amfani da vacuum impregnation process, tare da tsarin mechanical mai yawa, yana da kyau a kan 1100kV GIS DS unit
Aramid fiber-reinforced composite materials: take soke tsarin lightweight da fatigue resistance, ta shafi muhimmiyar tensile strength values na instability a cikin ultra-high voltage insulation torsion bars
Innovation na aiki
Vacuum dipping process: An yi amfani da ita don tabbatar da abubuwa na technical difficulties na forming ultra-high voltage insulation rods, ta haka zai iya samun internal structure mai tsari da ba da defect
Threadless bonding technology: Yana bukatar stress concentration wadanda ke faru ne a cikin threaded structures da kuma yana haɗaƙa tsarin reliability
Standard basis
Ta da dacewa da GB/T 11022-2020 da IEC 60694 standards, ta shafi muhimmiyar long-term operation requirements na ultra-high voltage equipment
