As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments such as wind, sun, rain, snow, frost, and sand erosion for a long time. The cable insulation layer is prone to aging and damage, the junction box is prone to water leakage, and the grounding device is prone to corrosion and failure, leading to a decrease in insulation performance and grounding faults, causing safety accidents such as leakage, short circuit, electric shock, and lightning strikes, seriously threatening personnel safety and the stable operation of the power plant. Traditional testing tools have single functions, complicated operations, and weak anti-interference capabilities. They require carrying multiple instruments back and forth for operation, making it difficult to meet the safety testing needs of insulation, grounding, conductivity, and other scenarios in photovoltaic power plants. Suzhou LAILX focuses on the pain points of photovoltaic electrical safety operation and maintenance, and has launched the LXH601 insulation grounding comprehensive tester. With integrated design, high-precision detection capability, and intelligent operation experience, it provides a one-stop solution for electrical safety testing of photovoltaic power plants, and strengthens the defense line for safe operation of power plants.

Insulation performance and grounding reliability are the two core cornerstones of electrical safety in photovoltaic power plants. Insulation resistance testing can evaluate the insulation status of components, cables, inverters, and other equipment, timely detect hidden dangers such as insulation aging, damage, and moisture, and prevent leakage and electric shock accidents; The grounding resistance test can detect the effectiveness of the grounding device, ensure that the fault current is quickly introduced into the ground, and avoid the risk of equipment burnout and lightning damage; Conducting tests, voltage detection, polarity testing, etc. are key means of troubleshooting electrical connection faults and ensuring the normal operation of the system. In the traditional detection mode, operation and maintenance personnel need to carry multiple devices such as insulation resistance meters, grounding resistance testers, conductivity testers, and multimeters, frequently switching between instruments and wiring. The operation process is cumbersome, inefficient, and the cumulative error of multiple devices is large, which affects the accuracy of detection. LAILX relies on years of experience in the research and development of photovoltaic electrical testing equipment, combined with a large amount of on-site application feedback, to independently develop the LXH601 insulation grounding comprehensive tester, breaking the limitations of traditional equipment "one machine, one use", achieving multi parameter integrated testing, greatly improving operation and maintenance efficiency and detection accuracy.

The core advantage of LXH601 Insulation and Grounding Comprehensive Tester lies in its integrated multifunctional design, which combines more than ten core functions such as insulation resistance testing, grounding resistance testing, conduction testing, AC/DC voltage detection, polarity testing, Voc/Lsc testing, and insulation fault location. One device can complete the full scene electrical safety testing of photovoltaic power plants without frequent switching of equipment and wiring, and the efficiency of a single inspection can be improved by more than 40%. The device supports bipolar mode detection and can simultaneously measure the insulation resistance of the positive and negative poles of the circuit to ground, accurately evaluating the insulation status of the device; Equipped with insulation fault location function, it can accurately locate fault points such as cable damage, junction box water leakage, component insulation layer damage, etc., facilitating quick maintenance and replacement by operation and maintenance personnel, and reducing system downtime. At the same time, the equipment is suitable for the detection requirements of the 1500V high-voltage system in photovoltaic power plants, with a wide range of voltage measurement, a wide range of insulation resistance measurement, and high accuracy of grounding resistance measurement, fully covering the electrical safety detection parameter requirements of photovoltaic power plants.

In terms of detection accuracy and performance stability, LXH601 performs excellently, providing reliable data support for the safety inspection of photovoltaic power plants. The equipment adopts high-precision measurement chips and anti-interference circuit design, effectively resisting outdoor complex electromagnetic environment interference, and the detection data is stable and reliable; The measurement accuracy of insulation resistance is ± (2%+2 words), the measurement accuracy of grounding resistance is ± (3%+0.1 Ω), and the measurement accuracy of voltage is ± (1%+1 words), accurately capturing small parameter changes and timely detecting potential hazards in the early stage. The device supports both AC and DC power supply, with a built-in large capacity rechargeable lithium battery for long-lasting endurance, meeting the needs of all day field inspection operations; Equipped with overvoltage, overcurrent, reverse connection, and short circuit protection functions, ensuring the safety and stability of the testing process, and avoiding equipment damage and personnel electric shock risks. At the same time, the equipment adopts an industrial grade design that is dustproof, waterproof, and drop resistant, which can adapt to harsh outdoor environments such as high temperature, low temperature, humidity, and sand and dust, and meet the long-term needs of field operations.

The intelligent and convenient operation design is an important highlight of LXH601's adaptation to photovoltaic field operation and maintenance, significantly reducing the operating threshold and improving operational efficiency. The device is equipped with a high-definition color touch screen, with a simple and intuitive interface in both Chinese and English, clear functional layout, and can be quickly mastered without professional training; Support one click detection process, automatically complete parameter settings, data collection, and result analysis. After the detection is completed, the qualified/unqualified judgment will be automatically displayed, making it easy for operation and maintenance personnel to quickly judge the equipment status. The internal memory can store a large amount of test data, support data classification management, historical record query, and one click export, making it easy to archive, analyze, and generate operation and maintenance reports; The supporting data management software can realize data viewing, analysis, and printing on the computer side, providing data support for power plant operation and maintenance management. At the same time, the device is equipped with a portable backpack, which is lightweight and easy for a single person to carry to various testing sites, suitable for full scene operation and maintenance needs such as ground power stations, distributed photovoltaics, and household photovoltaics.

The application scenarios of LXH601 insulation grounding comprehensive tester cover the entire life cycle electrical safety testing of photovoltaic power plants, and its value is significant. During the construction and acceptance stage of the power station, insulation, grounding, and conductivity full parameter testing can be carried out on components, cables, inverters, combiner boxes, distribution cabinets, and other equipment to ensure compliance with equipment installation and reliable electrical connections, and to avoid putting unqualified equipment into operation; During the daily operation and maintenance inspection stage, comprehensive inspections of the electrical system of the power station can be conducted regularly to promptly detect hidden dangers such as insulation aging, grounding corrosion, and cable damage. Safety risks such as leakage, short circuits, and lightning strikes can be identified in advance to ensure the stable operation of the power station; In the troubleshooting stage, insulation faults, grounding faults, poor conductivity and other problem points can be quickly located, shortening the troubleshooting time, reducing operation and maintenance costs, and minimizing power generation revenue losses; In scenarios such as third-party testing, power plant asset evaluation, and insurance loss assessment, accurate and authoritative electrical safety testing data can be provided, providing reliable basis for related work.
