As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time, experiencing wind, sun, rain, snow, frost, sand and dust erosion. The insulation performance and grounding reliability of their electrical systems are constantly facing severe tests. Aging cables, water leakage in junction boxes, damaged insulation layers of components, loose grounding connections, and other issues can easily lead to a decrease in insulation performance and grounding faults, resulting in major safety accidents such as leakage, short circuits, electric shock, and fires. This not only threatens the personal safety of operation and maintenance personnel, but also causes equipment damage, power plant shutdown, and huge economic losses. Regularly conducting professional insulation and grounding inspections to promptly identify and eliminate electrical safety hazards is the core prerequisite for ensuring the stable operation of photovoltaic power plants. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of photovoltaic electrical safety testing and innovatively develops the LXH601 insulation and grounding comprehensive tester. It integrates multiple functions such as insulation testing, grounding testing, voltage and current testing, and fault location. With the core advantages of precise detection, efficient operation and maintenance, and safety and reliability, LAILX provides comprehensive protection for the electrical safety of photovoltaic power plants and has become an essential tool for electrical safety testing of photovoltaic systems.

As a comprehensive testing equipment tailored for photovoltaic power plants, LXH601 has focused on the 1500VDC high-voltage electrical safety testing needs of photovoltaic systems since its research and development. The whole machine integrates more than ten core functions such as voltage and current testing, continuity grounding testing, polarity testing, Voc open circuit voltage testing, Lsc short circuit current testing, insulation resistance testing, insulation fault location, and grounding resistance testing. It is versatile and does not require multiple single function devices, greatly reducing equipment procurement costs and operation and maintenance management difficulties. It perfectly adapts to the electrical safety testing scenarios of photovoltaic power plant components, strings, inverters, combiner boxes, cables, and other links. The equipment adopts an integrated portable design, compact structure, lightweight, and is equipped with a high-strength protective box. It is dustproof, waterproof, and shockproof, making it easy to carry to various complex photovoltaic power plant scenarios such as mountains, deserts, and rooftops. A single person can quickly complete equipment deployment and operation, greatly improving the flexibility of outdoor testing operations.

In terms of core detection performance, LXH601 achieves precise measurement of insulation resistance, grounding resistance, voltage, current and other parameters with its self-developed high-precision detection module, achieving industry-leading detection accuracy. The range of insulation resistance testing covers 0-10G Ω, suitable for insulation performance testing of photovoltaic modules, cables, inverters and other equipment. It can accurately detect insulation layer aging, damage, moisture and other issues, and timely detect potential leakage hazards. The range of grounding resistance testing covers 0~100 Ω, which can quickly detect the grounding resistance value of the power station grounding system, judge whether the grounding connection is reliable, and avoid electric shock and fire accidents caused by poor grounding that cannot discharge fault current. Voltage and current testing can accurately measure parameters such as open circuit voltage, short circuit current, operating voltage, and operating current of photovoltaic strings. Combined with insulation and grounding detection, it comprehensively evaluates the electrical operation status of photovoltaic systems.

Accurate positioning of insulation faults is the core innovative advantage of LXH601, which completely solves the pain point of traditional detection equipment that can only detect insulation abnormalities and cannot locate the fault point. The equipment adopts patented insulation fault location technology, which can accurately locate the specific location of insulation faults in photovoltaic systems, such as cable damage points, junction box water leakage parts, component insulation layer damage points, etc. The positioning accuracy is high, and there is no need to investigate each section, greatly reducing the fault investigation time, helping operation and maintenance personnel to quickly and accurately repair, reducing system downtime, and minimizing power generation losses. Simultaneously supporting continuous grounding testing and polarity testing, it can detect whether the grounding circuit is conductive and whether the component polarity is correct, avoiding equipment damage and safety accidents caused by grounding circuit breakage and polarity reversal, fully covering the electrical safety testing needs of photovoltaic systems.

To adapt to complex outdoor work environments and high-pressure detection scenarios, LXH601 strives for excellence in safety, stability, and user-friendly design. The equipment adopts a high-voltage isolation design and has multiple safety protection mechanisms such as overvoltage, overcurrent, reverse connection, overheating, and leakage protection, effectively avoiding safety risks during high-voltage detection and ensuring the safety of operators and equipment. The body is made of high-strength engineering materials and has an IP54 dustproof and waterproof rating, which can adapt to harsh outdoor environments such as rain, snow, sand, and high temperatures. It is sturdy, durable, and resistant to falls and earthquakes, greatly improving the stability and service life of the equipment under complex working conditions. Equipped with a high-definition LCD display screen, it supports clear visibility under sunlight, with a Chinese operation interface, simple and intuitive menus, and simplified operation processes. Even non professionals can quickly get started after simple training, effectively reducing the operating threshold.

Data management and endurance design fully meet the practical needs of outdoor operation and maintenance of photovoltaic power plants. The device is equipped with a large capacity storage, which can store tens of thousands of sets of detection data. It supports one click data export and is compatible with common formats such as Excel, making it convenient for users to analyze data, generate reports, and archive storage. Equipped with a large capacity rechargeable lithium battery and low-power design, it can support high-intensity testing operations for more than 8 hours continuously when fully charged, meeting all day outdoor operation and maintenance needs. At the same time, it supports charging and using at the same time, avoiding detection interruptions caused by power outages. In addition, the device supports uploading detection data to the cloud, and with the support of the Lexus Photovoltaic Cloud Platform, it can achieve remote data viewing, historical trend analysis, fault warning and other functions, helping users achieve intelligent management of electrical safety detection data and precise operation and maintenance decision-making.

With comprehensive functional configuration, accurate detection performance, and reliable safety design, the LXH601 insulation grounding comprehensive tester has been widely used in the entire life cycle scenarios of pre grid acceptance, daily operation and maintenance inspection, fault diagnosis, and annual safety testing of photovoltaic power plants. Whether it is high-voltage string detection for mountainous photovoltaic power stations, narrow space operation and maintenance for rooftop power stations, or wet environment detection for water surface power stations, LXH601 can operate stably, accurately complete detection tasks, timely discover and eliminate electrical safety hazards, and ensure the safe and stable operation of the photovoltaic power station's electrical system. Since its listing, LXH601 has served thousands of domestic photovoltaic enterprises, EPC companies, and operation and maintenance institutions, covering various photovoltaic power station scenarios.
