Solusyon sa High Voltage Disconnect Switch para sa Malubhang Panahon (Bagyo, Malakas na Ulan) sa Pilipinas

Project Background​
Nahimutang sa kanlurang Pasipiko typhoon belt, ang Pilipinas ay nakakaranas ng higit sa 20 tropikal na bagyo taun-taon, kung saan may humigit-kumulang 5 ang naging napakalakas na mga bagyo (halimbawa, ang Typhoon Haiyan noong 2013 na nag-udyok ng 7,500 namatay, at ang Typhoon Odette noong 2021 na nag-disable ng 95 transmission lines). Nagdudulot ang mga bagyo ng maraming banta sa power infrastructure sa pamamagitan ng malakas na ulan, pagbaha, corrosion ng asin, at malakas na hangin:

1. ​Electrical Failures: Ang pagbaha ay sumasabog sa mga substation, nagiging sanhi ng short circuit sa ​High voltage Disconnect Switch​ systems, habang ang humidity ay nagiging sanhi ng insulation failure.
2. ​Structural Damage: Ang malakas na hangin ay nagpapabagsak ng mga transmission towers, nagdeform at nagjajam ng mga mekanikal na bahagi ng ​High voltage Disconnect Switch​ installations.
3. ​Voltage Fluctuations: Ang hindi matatag na voltage sa panahon ng post-disaster grid restoration (440V industrial voltage sa Pilipinas versus 380V para sa Chinese equipment) ay nagpapabilis ng pagkasira ng ​High voltage Disconnect Switch​.
   Ang tradisyonal na ​High voltage Disconnect Switch​ ay kulang sa sapat na disaster resilience, kaya kinakailangan ang targeted upgrades upang palakasin ang robustness ng grid.

​Solution​
​I. Environment-Adaptive Design​

1. ​Corrosion Resistance and Sealing Enhancement​
• Inalis ang porcelain insulators at pinalitan ng composite silicone rubber insulators para sa ​High voltage Disconnect Switch, nagdagdag ng 40% sa bending strength at resistive sa salt spray corrosion (mahalaga para sa coastal areas).
• Na-upgrade ang enclosure ng ​High voltage Disconnect Switch​ sa IP68 rating, puno ng dry nitrogen upang iwasan ang pagpasok ng baha at condensation.
2. ​Wind and Seismic Resistance​
• Isinama ang aerodynamic spoilers sa mga tower ng ​High voltage Disconnect Switch​ upang bawasan ang wind load ng 30%.
• Idinagdag ang 3D hydraulic shock absorbers sa mga base ng ​High voltage Disconnect Switch​ upang matiisin ang Category 16 typhoons at Magnitude 8 earthquakes.

​II. Smart Monitoring and Rapid Disconnection System​

​III. Modular Rapid-Replacement Design​

• ​Plug-in contact units: Pre-encapsulated ​High voltage Disconnect Switch​ cores cut replacement to 4 hours.
• ​Voltage-adaptive module: Integrated 440V/380V transformer ensures ​High voltage Disconnect Switch​ compatibility.

​IV. Supporting Defense Systems​

1. ​Grid-Based Deployment: ​High voltage Disconnect Switch​ density increased by 50% in high-risk areas (e.g., Luzon, Visayas).
2. ​Digital Twin Platform: Simulates typhoon impacts on ​High voltage Disconnect Switch​ networks.

​Outcomes​

1. ​Enhanced Disaster Resilience​
• During Typhoon Taozi (2024), ​High voltage Disconnect Switch​ reduced failure rates by 82% in Luzon pilot zones.
• ​High voltage Disconnect Switch​ prevented 23 flooding-induced short circuits, avoiding cascading blackouts.
2. ​Economic Efficiency Optimization​
