Photovoltaic power plants belong to high-voltage direct current electrical systems, and their components are subject to long-term exposure to sunlight, rain, snow, dust, and bird droppings, which can easily produce hot spot effects; Loose junction terminals, aging cable insulation, abnormal inverter power modules, poor grounding contact and other electrical faults in the combiner box can all be accompanied by local abnormal temperature rise. Such subtle heating hazards cannot be identified by human eyes or ordinary temperature guns. Long term neglect can cause major safety accidents such as component burnout, line short circuits, and power plant fires, resulting in huge economic losses and personal safety risks. Infrared thermal imaging detection is currently the most efficient technical means for photovoltaic preventive maintenance and thermal hazard investigation. Traditional handheld thermal imagers have shortcomings such as insufficient temperature measurement accuracy, blurry images, unclear outdoor strong light, short battery life, and lack of photovoltaic exclusive analysis functions. Suzhou Laikesi LAILX focuses on the exclusive needs of thermal safety detection in the photovoltaic industry, and has launched the LX-F100 handheld infrared thermal imaging device. With four advantages of high-definition infrared imaging, ultra-high temperature sensitivity, customized photovoltaic algorithms, and portable and durable body, it has become a standard equipment for comprehensive thermal fault inspection of photovoltaic power plants, synchronously adapting to multiple scenarios such as power operation and maintenance, industrial equipment temperature measurement, and building energy conservation detection.

The LX-F100 adopts an ergonomic integrated handheld body design, with a total weight of only 780g. It can be held with one hand for a long time without fatigue during inspection. The anti slip rubber handle is suitable for outdoor glove operation, and the compact body can be directly placed in the operation and maintenance tool kit for easy carrying. It is flexible and convenient for large-scale rapid scanning of photovoltaic systems on roofs, mountains, and greenhouses. The shell is made of high-strength impact resistant composite material, with an IP54 dustproof and waterproof protection level, which can resist outdoor splashing rain, sand and dust particle erosion. The working temperature range covers -20 ℃ to 50 ℃, and power stations in the northwest high temperature Gobi, northeast low temperature mountainous areas, and southern high humidity coastal areas can all operate stably. The device is equipped with a large capacity lithium battery, which can continuously perform imaging detection for 6 hours on a single full charge. It supports Type-C fast charging, and operation and maintenance personnel can conduct outdoor inspections throughout the day without the need for intermediate charging; The body is equipped with a 3.5-inch high brightness high-definition touch display screen. The screen image is clear and non reflective under strong outdoor noon light. It is paired with a multi-color pseudo color display mode, which provides strong color contrast in high-temperature abnormal areas and can easily identify small temperature difference faults at a glance.

The core imaging and temperature measurement performance reaches the top level of mid-range equipment in the industry. The LX-F100 is equipped with a high-performance uncooled infrared detector with an infrared resolution of 256 × 192 and a thermal sensitivity as low as 0.06 ℃. It can capture the subtle temperature difference of 0.06 ℃ between photovoltaic modules and electrical equipment, accurately locating early heating hazards that conventional temperature measurement equipment cannot detect. The temperature measurement range supports intelligent switching from -20 ℃ to 350 ℃, fully covering the temperature measurement needs of photovoltaic modules, combiner boxes, inverters, distribution cabinets, and cable trays. The temperature measurement accuracy is ± 2 ℃ or ± 2% reading (whichever is larger), and supports custom correction of emissivity, distance compensation, and automatic compensation of environmental temperature and humidity. The temperature measurement data is stable and reliable in outdoor environments with varying sunlight, strong winds, and temperature differences, and there will be no data drift or misjudgment. The device is equipped with visible light infrared image fusion function, and the thermal imaging image is synchronously overlaid with the real visible light image. It accurately locks the position of the component battery cells, wiring terminals, and cables corresponding to the hot spot, avoiding the problem of only seeing high-temperature areas and unable to locate the fault point; Supports 1 to 8 times continuous digital zoom, and upon detecting anomalies during remote scanning of the entire photovoltaic array, magnifies the image to finely examine minor heating faults, meeting the dual requirements of large-scale rapid inspection and local accurate diagnosis.

The instrument is equipped with LAILX exclusive photovoltaic intelligent analysis algorithm, which optimizes the recognition logic for common thermal faults in the photovoltaic industry. When scanning the photovoltaic array, typical defects such as component hot spots, junction box overheating, series parallel mismatch heating, and poor grounding of the frame heating are automatically marked. The screen displays the highest temperature, lowest temperature, and average temperature values in real time, and automatically marks the coordinates of high temperature points. Operation and maintenance personnel do not need professional thermal imaging interpretation knowledge to quickly distinguish between normal temperature rise and dangerous fault temperature thresholds. The device supports photography, short video recording, and storage. The local memory can store tens of thousands of thermal imaging raw images, and each image automatically synchronizes the shooting time and temperature parameters. It supports Type-C direct connection to a computer and Bluetooth wireless transmission of image data. It is equipped with LAILX thermal imaging analysis software to export temperature measurement reports in batches, including thermal imaging raw images, temperature data statistics tables, and fault risk classification suggestions. It is used for archiving power station operation and maintenance records and tracing safety hazards rectification. At the same time, the device is equipped with a built-in laser positioning indicator light, and the high-temperature area on the screen corresponds one-to-one with the laser point. During high-altitude remote inspection, the specific location of the fault can be quickly locked, reducing the difficulty of high-altitude troubleshooting.

Multiple safety and practical functions are suitable for photovoltaic high-voltage operation scenarios. The LX-F100 is equipped with a high-temperature sound and light warning mechanism, which can customize the safety temperature threshold. Once a heating area exceeding the set temperature is detected during scanning, the device will synchronously emit a buzzing alarm and a red highlighted reminder on the screen, alerting the operation and maintenance personnel of safety hazards in the first time and avoiding the omission of major fire risks. The body has no exposed metal conductive parts, and the insulated shell is suitable for close range detection of high-voltage photovoltaic equipment, so there is no need to worry about the risk of electric shock; The operation logic is minimalist, with one click access to photovoltaic inspection mode upon startup. Three exclusive temperature measurement parameters are preset for components, distribution cabinets, and inverters, which can be used directly upon startup, eliminating the need for repeated debugging steps. Zero basic staff can operate proficiently in five minutes.

Since its launch on the market, the LX-F100 handheld infrared thermal imaging device has been widely used in centralized ground photovoltaic annual safety inspections, distributed roof photovoltaic quarterly hazard inspections, power station completion safety acceptance, component production hot spot factory screening, energy storage inverter temperature monitoring and other scenarios. Multiple new energy operation and maintenance enterprises have reported that the installation of this equipment has more than doubled the efficiency of early thermal hazard investigation in power plants. A large number of hidden small heat spots and loose wiring heating problems have been detected in advance, effectively reducing economic losses caused by component burnout and fire accidents; The third-party security testing agency uses this equipment to complete the power station security assessment, with accurate and stable temperature measurement data, and the testing report has complete reference value.

Suzhou LAILX is deeply involved in the field of photovoltaic detection and safety equipment. The LX-F100 handheld infrared thermal imaging device combines affordable pricing with professional level detection performance, significantly reducing the procurement threshold for thermal imaging equipment for small and medium-sized photovoltaic operation and maintenance enterprises.
