Ang insulating torsion bar para sa 252-1100kV GIS isolation switch mao ang core transmission component sa ultra-high voltage gas insulated metal enclosed switchgear (GIS). Ang mga teknikal nga karakteristika ug engineering application points niini mao kini:
1、 Core performance requirements
Electrical insulation performance
Kinahanglan nito molambo og power frequency voltage sa 252-1100kV (tulad sa pagpasa sa 1.1 × 1100kV/5-minute power frequency withstand voltage test para sa 1100kV GIS) ug lightning impulse voltage (1.1 × 2400kV)
Ang partial discharge capacity kinahanglan nga ≤ 1.5pC (sa 1.2 × 635kV conditions) aron masiguro ang long-term operational stability
Mechanical performance
Tensile strength ≥ 300kN, mechanical life ≥ 10000 opening and closing operations, suitable for high impact loads (tulad sa 40kA short-circuit current breaking)
Ang dynamic response frequency kinahanglan molambo sa 0-600Hz aron iwasan ang resonance risk
2、 Breakthrough in Materials and Craftsmanship
Key materials
Epoxy glass cloth tube: gihimo pinaagi sa vacuum impregnation process, may taas nga mechanical strength, suitable for 1100kV GIS DS unit
Aramid fiber-reinforced composite materials: nag-improve sa lightweight ug fatigue resistance, nag-solve sa problema sa unstable tensile strength values sa ultra-high voltage insulation torsion bars
Process innovation
Vacuum dipping process: Nag-overcome sa technical difficulties sa pag-form sa ultra-high voltage insulation rods, nag-achieve og dense ug defect free internal structure
Threadless bonding technology: nag-iwas sa stress concentration resulta sa threaded structures ug nag-improve sa reliability
Standard basis
Compliant sa GB/T 11022-2020 ug IEC 60694 standards, nag-meet sa long-term operation requirements sa ultra-high voltage equipment
