An infrared measurement window is a transparent window installed on the door or side panel of an electrical cabinet. Made from specific materials (e.g., infrared-transparent materials), it allows infrared thermometers to detect the thermal radiation signals from equipment inside the cabinet without opening it.
1. Safety: Allows temperature measurement without opening the cabinet, avoiding exposure to high-voltage environments.
2. Efficiency: Enables quick temperature detection without system downtime or power interruption.
3. Accuracy: Special infrared materials ensure undistorted infrared signals for precise temperature measurements.
4. Equipment Protection: Timely detection of abnormal temperatures prevents overheating or short-circuit failures of electrical components.
- High-voltage equipment: Thermal management monitoring for transformers, circuit breakers, and busbars.
- Low-voltage distribution cabinets: Used in distribution panels, switchgear, and control cabinets.
- Industrial applications: Real-time monitoring in factories, data centers, rail transportation, petrochemical facilities, etc.
Material Properties
Infrared Glass | High transmittance and heat resistance, suitable for high-precision measurements. |
Polymer Crystals | Cost-effective, ideal for general industrial use, with corrosion and impact resistance. |
Metal Mesh | Offers electromagnetic shielding, suitable for environments with high electromagnetic interference. |
- Installation location: Typically installed on the cabinet door or side panel in an accessible position for easy operation.
- Usage precautions: Ensure the window remains clean to prevent dust or dirt from affecting infrared signal transmittance.
Regularly inspect the window's seal to prevent moisture or dust ingress.
Calibrate the infrared thermometer based on the transmittance parameters of the window material.
Standards: IEC 62271 (High-voltage equipment standards); IEEE C37.20.7 (Protection and monitoring requirements for electrical cabinets).
With the development of smart grids, infrared measurement windows are increasingly integrated into intelligent monitoring systems. Combining with temperature sensors and wireless monitoring technologies, they enable remote real-time monitoring and support the intelligent operation and maintenance of electrical equipment.
