आधुनिक विद्युत प्रणालियों में थर्मल प्रबंधन की चुनौती

जैसे-जैसे बिजली की मांग बढ़ती है, आधुनिक विद्युत बुनियादी ढांचे को थर्मल प्रबंधन चुनौतियों का सामना करना पड़ता है, विशेष रूप से रेलवे परिवहन प्रणालियों जैसे महत्वपूर्ण अनुप्रयोगों में. पारंपरिक तापमान निगरानी विधियाँ कई महत्वपूर्ण सीमाओं से ग्रस्त हैं:

• संकीर्ण कवरेज क्षेत्र जो विद्युत प्रणालियों के महत्वपूर्ण हिस्सों को निगरानी रहित छोड़ देते हैं
• Inability to perform continuous real-time temperature measurement
• Limited multi-point measurement capabilities
• Labor-intensive inspection processes requiring significant human resources

These limitations create substantial safety gaps, as evidenced in a case study of a railway transportation power system where overheating issues in cables and switchgear cabinets presented significant fire hazards and operational risks.

The Science Behind Distributed Fiber Optic Temperature Sensing

वही डीटीएस तकनीक implemented in this system leverages the रमन प्रकीर्णन प्रभाव to achieve precise temperature measurements across distributed locations. Here’s how this sophisticated technology works:

मौलिक संचालन सिद्धांत

When laser pulses travel through an optical fiber, they encounter microscopic inhomogeneities in the fiber’s refractive index. These interactions cause scattering events that create both Stokes and Anti-Stokes Raman backscatter components. The mathematical relationship can be expressed as:

• Stokes Raman scattering: vs = v0 – Δv
• स्टोक्स विरोधी रमन बिखर रहे हैं: vas = v0 + Δv

Where v0 represents the incident photon frequency and Δv represents the Raman phonon frequency.

Temperature Measurement Method

The ratio between the Anti-Stokes and Stokes intensities exhibits a temperature dependency that can be expressed as:

Ias/Is = (vas/vs)⁴ × exp(-h×Δv/k×T)

कहाँ:

• Ias represents Anti-Stokes light intensity
• Is represents Stokes light intensity
• h is Planck’s constant
• k is Boltzmann’s constant
• T is the absolute temperature

By analyzing the ratio between these scattering components, वही system can precisely determine temperature at any point along the fiber with exceptional accuracy. The reference temperature calibration method further enhances measurement precision.
