Distribution cabinets play an important role in power distribution and control, protection and safety, and improving energy utilization in the power system. There are numerous components and wiring terminals inside the cabinet, and the heat generated accumulates, posing a threat to equipment safety. Therefore, timely monitoring of the temperature distribution inside the cabinet is particularly important for improving the operation and maintenance level of the distribution cabinet.
Handheld thermal cameras are devices designed to detect and visualize thermal radiation emitted from objects. By converting this thermal energy into a visual format, these cameras allow users to identify temperature differences across various surfaces. This capability is crucial in applications where overheating could lead to severe consequences.
The use of infrared thermal imaging cameras for efficient inspection of distribution cabinets can quickly detect the temperature of important equipment or critical parts such as cables, switches, and wiring terminals, greatly improving the convenience of detection and ensuring the stable use of electricity by end users.
When selecting a handheld thermal camera for monitoring distribution cabinets, several key features should be considered:
Temperature Range: The camera should be capable of measuring a broad temperature range, typically from -20°C to 400°C (-4°F to 752°F), to cover various electrical components.
Resolution: Higher resolution (e.g., 320x240 pixels or more) provides clearer thermal images, making it easier to identify localized hot spots that may indicate potential failures.
Accuracy: An accuracy rating of ±2°C or better ensures reliable temperature readings, which is crucial for preventive maintenance and safety inspections.
Thermal Sensitivity: A lower thermal sensitivity (NETD) value, ideally less than 50 mK, allows for the detection of small temperature differences, enhancing diagnostic capabilities.
User-Friendly Display: A clear, high-resolution display is essential for real-time viewing and analysis of thermal images.
Connectivity Options: Features like Wi-Fi, Bluetooth, or USB facilitate easy data transfer and reporting, enabling technicians to document findings efficiently.
Durability: A rugged design with an IP rating (e.g., IP54) ensures the camera can withstand harsh environments often found in industrial settings.
Battery Life: Long battery life is crucial for extended use, allowing technicians to perform thorough inspections without frequent recharges.
