Tingkad-tingkad nga Solusyon para sa Voltage Transformer nga Air-Insulated Switchgear nga Orihentado sa Kaligtasan
Analisis sa Punto sa Sakit sa Industriya
Ang tradisyonal nga mga voltage transformer kasagaran adunay duha ka major nga kahigpiton sa kaligtasan ha mga harsh nga kondisyon:
- Panganib Ha Pag-quake: Ang mga porcelain insulator mahimong madako ha pag-quake o impact han short-circuit current, nagresulta ha secondary short-circuit explosion.
- Panganib Ha Pag-rupture: Ang metal enclosure susceptible ha pag-rupture ha internal arc faults, an SF₆ gas leakage nag-agrabyado han severity han accident.
Innovative nga Solusyon nga Arkitektura
I. Triple Seismic Protection System
• Dynamic Decoupling Base: Patented hydraulic damping device + spring energy storage mechanism (IEC 61166:2025 certified for Seismic Intensity 9).
• Flexible Current-Carrying Connection: Bellows-type conductive circuit design (±15mm axial/±8mm radial displacement tolerance).
• Composite Insulation Support: Glass fiber-reinforced epoxy resin pillars (380MPa flexural strength, 3.2× higher than porcelain).
II. Active Defense Explosion-Proof Structure
Pressure Monitoring → Rapid Pressure Relief → Directed Emission → Mechanical Isolation
• Nano-Ceramic Matrix Composite Enclosure: ≥120MPa flexural strength, 400% higher impact toughness vs. traditional steel.
• Dual-Channel Pressure Release System: Rupture disc (0.15MPa activation) + labyrinthine gas flow channel (≥800mm arc flame decay length).
• Arc Energy Graded Dissipation: Copper-tungsten alloy arc chute plates + ZnO non-linear resistors for suppression.
III. Full-Range Environmental Adaptability Design
• Dry-Type Solid Insulation System:
o Vacuum-cast epoxy/silicone rubber composite dielectric (CTI ≥600V).
o Complete replacement of SF₆ gas (GWP=0, compliant with IEC 62271-1:2024 environmental requirements).
• IP6X Protection Level: Fully sealed structure resistant to mine dust/humidity.
• Wide-Range Temperature Compensation: Maintains 0.2 accuracy class from -40℃ to +85℃.
