1. High-Temperature Challenges: Why Do Traditional Devices Frequently Fail?
In environments above +40℃, traditional reclosers face severe challenges:
- Insulation Crisis: High temperature increases SF₆ gas leakage rate by 300%, reduces insulation performance by 40%, and significantly raises flashover risks.
- Mechanical Jamming: Lubricating oil viscosity drops by 60%, metal thermal deformation exceeds 0.5 mm, and mechanism failure rate rises 5 times.
- Control Failure: Electronic component junction temperature exceeds 120℃, protection maloperation rate reaches 2.1%, and communication interruptions occur frequently.
2. Core Technology: Triple Intelligent Protection System
Active Thermal Insulation System
- Physical Protection: Double-layer composite shell design, with an aerospace-grade sun-protective coating (UV reflectivity ≥ 90%) on the outer layer and nano-aerogel filling inside, reducing surface temperature by 15℃.
- Intelligent Temperature Control: Built-in semiconductor active cooling module, stabilizing the working chamber temperature within -20℃ ~ +45℃.
- Insulation Optimization: Eco-friendly dry air insulation with adaptive pressure regulation, completely eliminating SF₆ leakage risks.
High-Temperature Resistant Reinforced Design
- Mechanism System: High-temperature resistant alloy transmission mechanism matched with perfluoropolyether high-temperature grease (operating temperature: -30℃ ~ +280℃).
- Sealing System: Triple fluororubber sealing structure, temperature resistance class 230℃, IP67 protection grade.
Real-Time Monitoring & Early Warning
- 16-point distributed temperature monitoring
- Multi-dimensional sensing of pressure, humidity and displacement
