Hot spot effect, overheating of junction boxes, aging and heating of cables, and temperature rise of junction box joints are the most common safety hazards in photovoltaic power plants. Local abnormal heating caused by component cracking, shielding, loose wiring, diode failure, and other issues can result in continuous power attenuation of components, decreased power generation revenue, and even component burnout and cable fires, causing significant asset losses and personal safety risks to the power plant. Traditional manual inspection relies on visual observation and single point temperature gun detection, which can only identify obvious high-temperature faults on the surface, small hidden heat spots, and internal cable heating that are difficult to capture, resulting in extremely high missed detection rates. Large scale power plant inspections are time-consuming and labor-intensive, and the operation and maintenance costs are high. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the urgent need for outdoor thermal hazard investigation in photovoltaics. It has launched the LX-F100 handheld infrared thermal imaging device, which is equipped with an ultra high sensitivity infrared detector to achieve non-contact and non-destructive temperature measurement throughout the entire area, accurately capturing small temperature differences of 0.05 degrees Celsius. The lightweight handheld design is suitable for all day outdoor inspections, providing one-stop solutions to the pain points of heat hazard investigation in photovoltaic modules and electrical equipment. It has become a standard "thermal sensing probe" for photovoltaic operation and maintenance teams. Compact, portable, precise imaging

Infrared thermal imaging technology captures the invisible infrared radiation energy of objects, converts it into a visualized temperature distribution map, and synchronously measures temperature across the entire area. Compared with single point temperature measurement devices, it improves efficiency by tens of times. The LX-F100 is equipped with a 12 μ m high-sensitivity infrared photosensitive chip with an infrared resolution of 256 × 192. The detector's thermal sensitivity is as low as<0.05 ℃ @ 30 ℃, which can accurately distinguish extremely weak temperature differences. Even small hidden cracks inside the battery cell and slight virtual connections in the wiring terminals can be imaged clearly, completely avoiding single point temperature measurement and missed detection defects. The temperature measurement range of the equipment covers an ultra wide temperature range of -20 ℃ to 550 ℃, perfectly adapted for low-temperature environment inspection of photovoltaic modules, high-temperature electrical equipment testing of inverters, combiner boxes, and distribution cabinets; Built in multiple intelligent temperature measurement modes, including full screen high and low temperature automatic tracking, center point temperature measurement, area frame selection temperature measurement, temperature difference comparison analysis, one click locking of high temperature fault points, screen synchronous display of real-time temperature values and temperature difference, technical personnel can quickly determine the risk level of faults on site, distinguish between minor hidden dangers and emergency fire risk points, prioritize the disposal of high-risk heating equipment, and optimize the operation and maintenance sequence. The device supports the fusion and overlay display of infrared images and visible light images, with infrared thermal images overlaid with real-life images, accurately locating the components and cable numbers corresponding to the heating area, avoiding the inability to find the fault location during large-scale troubleshooting, and greatly reducing the fault location time.

The ergonomic lightweight design of the product is specially designed for long-term outdoor inspections. The whole machine is wrapped in anti slip and wear-resistant rubber, and the weight of a single handheld grip is less than 600g.

It can adapt to complex outdoor conditions such as rain, snow, sandstorms, and high salt spray on the beach, and is not afraid of harsh outdoor working environments in photovoltaic power plants. The power supply system is equipped with a large capacity lithium battery, with a single full charge range of up to 15 hours, fully covering all day power station inspection work. It is equipped with fast charging function, which can be fully charged in 2 hours. The low battery automatically pops up a window reminder to prevent power outages during inspections; The device has a built-in local storage space for over 1000 sets of images. The captured infrared thermal imaging images automatically come with watermarks for shooting time and real-time temperature data. It supports exporting images through both USB wired and wireless Bluetooth methods. Equipped with professional thermal imaging analysis software on the PC end, it can analyze temperature curves and fault trends of images, generate batch thermal hazard inspection reports, record the annual changes in heating faults of the power station, and provide data support for preventive operation and maintenance.

The LX-F100 is applied in the photovoltaic field to cover the inspection of all equipment in power plants. It can quickly scan and identify defects such as hot spots, PID decay heating, frame leakage current heating, and component delamination heating in photovoltaic modules; For electrical supporting equipment, accurately detect electrical hazards such as loose and heating of junction box terminals, overload and temperature rise of fuses, overheating of inverter power modules, aging and heating of AC/DC cable insulation, and heating of grounding circuit virtual connections; Simultaneously adapting to the thermal runaway warning detection of battery clusters in energy storage power stations, capturing abnormal temperature rise of battery modules in advance, and avoiding energy storage fire accidents. Except for the new energy photovoltaic industry, the equipment has strong universality and is widely used in various fields such as power grid operation and maintenance, preventive testing of industrial machinery and equipment, energy-saving and heat leakage detection of buildings, and troubleshooting of HVAC pipelines. The multi-purpose use of one machine reduces the equipment procurement investment of enterprises. In the operation and maintenance scenario of large-scale ground power stations, technicians use handheld devices to scan along the array channel at a constant speed. A single inspection can synchronously complete the temperature measurement of hundreds of components in the entire area, which is 80% more efficient than traditional temperature guns; Distributed rooftop photovoltaics do not require scaffolding and can perform high-altitude component thermal imaging detection from a distance, avoiding safety risks during high-altitude operations.
