Sang-ayon sa Kaligtasan na May Mataas na Pagkakataon ng Pagsisikap na Solusyon para sa Air-Insulated Switchgear Voltage Transformer
Pag-aanalisa ng Sakit ng Industriya
Ang mga tradisyonal na voltage transformers ay nakakaharap sa dalawang pangunahing panganib sa kaligtasan sa ilalim ng masamang kondisyon:
- Panganib sa Lindol: Ang mga porcelana insulator ay madaling mabali sa pag-impact ng lindol o short-circuit current, nagdudulot ng secondary short-circuit explosions.
- Panganib sa Pagkabali: Ang mga metal enclosure ay malungkot na nababali sa panahon ng internal arc faults, at ang paglabas ng gas na SF₆ ay nagpapalala sa grabe ng aksidente.
Arkitektura ng Mapanining na Solusyon
I. Triple Seismic Protection System
• Dynamic Decoupling Base: Patented na hydraulic damping device + spring energy storage mechanism (IEC 61166:2025 certified para sa 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× mas mataas kaysa sa porcelana).
II. Aktibong Defense Explosion-Proof Structure
Pressure Monitoring → Rapid Pressure Relief → Directed Emission → Mechanical Isolation
• Nano-Ceramic Matrix Composite Enclosure: ≥120MPa flexural strength, 400% mas mataas ang impact toughness kumpara sa tradisyonal na bakal.
• 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 para sa suppression.
III. Full-Range Environmental Adaptability Design
• Dry-Type Solid Insulation System:
o Vacuum-cast epoxy/silicone rubber composite dielectric (CTI ≥600V).
o Kompletong pagsasalitla ng gas na SF₆ (GWP=0, compliant sa IEC 62271-1:2024 environmental requirements).
• IP6X Protection Level: Fully sealed structure resistant sa mine dust/humidity.
• Wide-Range Temperature Compensation: Nagpapanatili ng 0.2 accuracy class mula -40℃ hanggang +85℃.
