Photovoltaic power plants are exposed to outdoor environments for a long time, resulting in frequent thermal faults such as component hot spots, overheating of junction boxes, oxidation and loosening of cable joints, abnormal temperature rise of combiner boxes and inverters, and poor grounding and heating. This type of temperature anomaly hazard is difficult to detect with the naked eye in the initial stage, and its continuous development can cause aging of component packaging, breakdown of circuit insulation, and at least a continuous decrease in power generation, and at worst, cause fires, resulting in significant property damage. Traditional inspections rely on temperature guns for single point temperature measurement, with limited coverage and high rates of missed detections, making it difficult to intuitively grasp the temperature distribution in the area. Suzhou Laikesi LAILX has launched the LX-F200 handheld infrared thermal imaging device, specially designed for photovoltaic operation and electrical safety testing. With non-contact full area temperature measurement, high-definition infrared imaging, and lightweight handheld design, it can quickly visualize and identify thermal hazards. It is widely used in daily inspections, completion acceptance, and emergency troubleshooting of various photovoltaic power plants. High sensitivity and clear imaging

The LX-F200 is equipped with a high-sensitivity infrared detector with excellent thermal sensitivity, which can capture small temperature differences and accurately identify various early thermal anomalies in photovoltaic systems. The equipment covers a wide temperature measurement range, meeting the temperature measurement needs of various types of equipment such as photovoltaic modules, DC cables, inverters, and box transformers. It supports the fusion display of visible light images and infrared heat maps, intuitively corresponding to heating points, and quickly locating the accurate location of faults. Different from single point temperature measurement devices, infrared imaging can complete the scanning of the entire photovoltaic array in one go, intuitively presenting the temperature distribution of the entire area. Operation and maintenance personnel can quickly distinguish between normal areas and abnormal heating areas, and the inspection efficiency is several times higher than traditional temperature measurement methods. It is very suitable for large-scale investigation of tens of megawatts of large photovoltaic power plants.

The equipment fully follows ergonomic design, with a lightweight and easy to carry inspection for a long time without fatigue. It is equipped with an outdoor high-definition display screen, and the image is clear under strong light. The body is equipped with physical shortcut buttons, which do not require complex menu operations. One click photography saves thermal images and automatically records the highest, lowest, and average temperature data of temperature measurement points. All heat maps with temperature measurement parameters are synchronously stored, supporting local playback and USB data export, and can be directly imported into a computer for analysis and archiving. The device is equipped with a built-in temperature difference alarm function, which can customize the temperature threshold. When the temperature difference in the area of the screen exceeds the set value, it will automatically remind inspection personnel to quickly identify potential risks, achieve preventive operation and maintenance, and complete the handling at the early stage of the fault, avoiding the continuous expansion of the fault.

In addition to hot spot detection of photovoltaic modules, LX-F200 is also suitable for testing the complete set of electrical equipment in photovoltaic power plants. It can be used to investigate scenarios such as heating of combiner box terminals, aging and heating of cable insulation, temperature rise of inverter power modules, and abnormal equipment in box transformers. It is versatile and reduces the cost of equipment procurement for enterprises. The whole machine shell is made of high-strength and wear-resistant materials, with excellent anti drop and dustproof performance, suitable for complex working conditions such as outdoor mountains, coastal high salt spray, and high temperature exposure. The device supports quick battery replacement, and the backup battery ensures uninterrupted inspection throughout the day without the need to stop charging midway. At the same time, it is equipped with comprehensive measurement tools that support regional temperature measurement, point temperature measurement, and temperature difference comparison, meeting the needs of refined analysis in different scenarios.

In the era of photovoltaic parity, cost reduction and efficiency improvement are the core goals of all power plant operators. Preventive operation and maintenance can significantly reduce major downtime losses and extend equipment service life. The LX-F200 handheld infrared thermal imaging device, with its balanced performance and practical design, meets the needs of small and medium-sized distributed photovoltaics and large-scale ground power stations. It is not only suitable for the new energy industry, but also can be extended to applications such as power inspection, building energy consumption detection, and industrial equipment temperature measurement. Suzhou LAILX is deeply involved in the field of photovoltaic testing equipment, continuously optimizing product functions based on feedback from frontline operation and maintenance sites, and providing supporting services such as equipment calibration and operation training. In the future, Lexus will continue to iterate infrared temperature measurement algorithms, promote the digital upgrade of photovoltaic thermal hazard inspection, and assist the operation and maintenance team in transforming from post repair to pre warning, comprehensively safeguarding the safe and stable operation of photovoltaic power plants.
