Solusyon sa Intelligent Operation para sa 12kV Vacuum Circuit Breakers: Pagsasama ng Real-time Monitoring & Lifetime Optimization

Ⅰ. Pagsasakatuparan at Pagmamaintain ng Equipment

Pagsasama-sama ng Intelligent Monitoring System

• ​Maramihang Real-time Monitoring: Ang mga embedded sensors (temperature, displacement, Hall effect current sensors) ay sumusunod sa pagtaas ng temperatura ng contact, mechanical characteristics (opening/closing speed, overtravel), coil current, at partial discharge signals. Ang data ay dadaan sa preprocessing gamit ang edge computing bago i-upload sa cloud.
• ​Lifetime Prediction Model: Dinadala ang electrical wear data (cumulative breaking current × arcing time) at mechanical wear data upang dinamikong i-evaluate ang natitirang lifetime, na nagbibigay ng alert para sa maagang pagpapalit.
• ​Case Study: Matapos ang deployment ng i-DVB circuit breakers sa Southeast Asian petrochemical plants, ang monitoring ng contact pressure (±5% accuracy) ay naka-reduce ng 30% ang downtime dahil sa fault.

Automated Operation Optimization

• ​Motorized Racking & Programmable Control: Nagbibigay ng remote racking in/out, na nakapagsasama ng Five-Protections Interlocking logic upang maiwasan ang misoperation. Ang self-adjusting motor torque ay nagse-ensure ng reliable contact engagement sa high-humidity environments.
• ​Self-Correcting Mechanical Characteristics: Ang angular displacement sensors ay nagbibigay ng real-time feedback sa contact gap. Ang automatic calibration ay mag-trigger kung ang contact rebound ay lumampas ng 2mm sa panahon ng opening, na nagsisimula ng mabawasan ang panganib ng arc reignition.

Ⅱ. Environmental Adaptability

Ⅲ. Localized Technical Support

• ​Training Centers: Ang mga regional bases sa Thailand at Vietnam ay nagbibigay ng AR-assisted fault simulation training sa English, Thai, at Vietnamese.
• ​Spare Parts Network: Ang 3-tier inventory system (Singapore hub → Malaysia/Indonesia → Philippines) ay nagse-ensure ng 48-hour delivery ng critical components (vacuum interrupters, limit switches).
• ​Rapid Response: Ang collaboration sa pagitan ng local engineers at remote experts ay nagsosolve ng 90% ng issues via the iMS platform; ang on-site response ay guaranteed within 4 hours para sa natitirang 10% ng cases.

Ⅳ. Fault Diagnosis & Preventive Maintenance

Smart Diagnostics

• ​Partial Discharge Early Warning: Ang UHF sensors ay nadetect ang signals >20pC, na nagpopredict ng insulation degradation na may >92% accuracy.
• ​Energy Storage Mechanism Fault Localization: Ang analysis ng motor current waveforms (e.g., continuous operation >5s) ay nag-iidentify ng stuck switches o gear wear.

Maintenance Strategy

Nagbabago mula sa scheduled to condition-triggered maintenance (e.g., triggered when contact wear ≥2mm or temperature rise >65°C), na nagsisimula ng mabawasan ang redundant inspections ng 40%.

Ⅴ. Lifecycle Cost Optimization

Ⅵ. Case Study: Manila Data Center, Philippines

• ​Challenge: Annual power outages (>12 times/year) at >8% breaker failure-to-operate rate dahil sa salt corrosion.
• ​Solutions:
• Deployed 12kV smart breakers with integrated temperature and partial discharge monitoring.
• Upgraded rooftop AC condensate drainage and cabinet sealing to NEMA 4X standards.
• Monthly health reports via the iMS platform.
• ​Results:
• Fault rate plummeted to 0.8%, saving $53,000/year in O&M costs.
• Lifespan extension deferred replacement by 3 years.
