Fiber Optic Temperature Monitoring System para sa mga Dry Type Transformer

A major power facility utilizes high-voltage dry type transformers as core power supply equipment. Since dry type transformers rely on air convection for cooling, accurate monitoring of winding hot spot temperatures proved challenging. Traditional PT100 sensors cannot directly contact high-voltage windings, creating temperature measurement blind spots and potential safety risks.

Our Solution

We deployed a Fiber Optic Temperature Monitoring System to achieve precise temperature control through the following implementation:

Installation Process

Fiber optic temperature sensors embedded directly into transformer winding hot spot areas
Precise positioning of fiber probes at locations most prone to high temperatures
Professional cable routing ensuring no interference with transformer heat dissipation
Connection to intelligent temperature monitoring device for real-time data acquisition

Mga Teknikal na Tampok

Intrinsically Ligtas: Fiber optic material provides electrical insulation, enabling direct contact with high-voltage windings
Superior EMI Immunity: Unaffected by transformer’s strong electromagnetic fields
Mataas na Katumpakan ng Pagsukat: Direct hot spot temperature measurement with ±1℃ precision
Pangmatagalang Katatagan: Heat resistant up to 180℃ with service life exceeding 20 taon

Mga resulta & Mga Benepisyo

The system has delivered remarkable outcomes since commissioning:

Real-time na Pagsubaybay: 24/7 continuous winding hot spot temperature monitoring with per-second data updates
Maagang Babala: Automatic alarms for temperature anomalies, detecting potential failures 48 hours in advance

Bakit Pumili ng Fiber Optic Monitoring?

Mga Bentahe sa Tradisyonal na Pamamaraan

Direktang Pagsukat ng Hot Spot: Hindi tulad ng mga sensor ng PT100 na sumusukat sa mga panlabas na temperatura, Ang mga fiber optic sensor ay maaaring direktang i-embed sa windings para sa tunay na hot spot monitoring.

Walang Electrical Interference: Ang pagiging non-conductive, inaalis ng mga fiber optic sensor ang mga alalahanin tungkol sa pagkasira ng kuryente, mga isyu sa saligan, o interference ng signal sa mga high-voltage na kapaligiran.

Disenyo na Panlaban sa Pagsabog: With no electrical components at the sensing point, fiber optic systems are intrinsically safe for use in hazardous locations.

Lightning Protection: Non-metallic fiber optic cables are immune to lightning strikes and electrical surges that can damage conventional wiring.

Operasyon na Walang Pagpapanatili: Solid-state sensing technology with no moving parts ensures decades of reliable operation without calibration or replacement.
