As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time. The cable insulation layer is prone to aging and damage, the junction box is prone to water seepage and moisture, and the grounding device is prone to corrosion and failure, leading to decreased insulation performance and grounding faults. This can easily cause safety accidents such as leakage, short circuits, electrical contact, and lightning strikes, seriously threatening personnel safety and stable equipment operation. Insulation performance and grounding reliability are the two core cornerstones of photovoltaic electrical safety, and regular insulation and grounding testing is crucial. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the needs of photovoltaic electrical safety testing and has launched the LXH601 insulation grounding comprehensive tester. With the core advantages of integrated design, accurate measurement, and fault location, LAILX has built a solid electrical safety defense line for photovoltaic power plants and ensured their stable and efficient operation.

Traditional photovoltaic electrical safety testing often uses single function equipment, and insulation testing, grounding testing, and voltage and current testing require the use of different instruments, which have problems such as cumbersome equipment carrying, complex operation processes, low detection efficiency, and difficult data linkage analysis, making it difficult to meet the rapid detection needs of the entire electrical system of photovoltaic power plants. The LXH601 insulation grounding comprehensive tester breaks the limitations of traditional equipment function separation, and combines voltage and current testing, continuity grounding testing, polarity testing Voc、Lsc、 More than ten functions, including insulation testing, insulation fault location, and grounding testing, are integrated into one machine to achieve "multi-purpose and comprehensive detection", greatly simplifying the detection process and improving operation and maintenance efficiency.

The core measurement performance is precise and reliable, suitable for the detection needs of photovoltaic high-voltage systems. The equipment adopts high-precision measurement modules, with a wide range and high accuracy in measuring insulation resistance. It can accurately detect the insulation performance of components such as photovoltaic modules, cables, and junction boxes, and timely detect hidden dangers such as insulation aging and damage. Accurate measurement of grounding resistance can effectively detect issues such as corrosion and loose connections in grounding devices, ensuring reliable conductivity of the grounding system and providing a safe discharge channel for lightning strikes and leakage faults. At the same time, it can accurately measure parameters such as photovoltaic system voltage, current, open circuit voltage (Voc), short-circuit current (Lsc), etc., comprehensively evaluate the operating status of the electrical system, and provide multi-dimensional data support for fault diagnosis.

Accurate fault location is the core technological advantage of LXH601. The equipment is equipped with self-developed insulation fault location technology, which can accurately lock the insulation fault points in the photovoltaic system, such as cable damage locations, junction box water leakage areas, component insulation layer damage areas, etc., without the need for step-by-step troubleshooting, greatly reducing the time for fault disposal and minimizing system downtime losses. Traditional insulation testing can only determine whether the insulation is abnormal and cannot locate the specific fault location. Maintenance personnel need to spend a lot of time troubleshooting each section. However, the fault location function of LXH601 can directly point to the fault location, making maintenance more efficient and accurate.

Portable and practical design that meets the on-site needs of photovoltaic operation and maintenance. LXH601 adopts an integrated compact design, with a sturdy and durable body, high protection level, and can adapt to harsh outdoor environments such as humidity, dust, high and low temperatures. It operates stably and reliably. The device is lightweight and small in size, paired with a portable case, making it easy for a single person to carry to any area of the power station without relying on a fixed testing site. The operation interface is simple and intuitive, equipped with a high-definition display screen, real-time display of measurement data and fault information, reasonable button layout, clear functional zoning, and operation and maintenance personnel can quickly get started without professional training. Support data storage and export, record historical detection data, generate detection reports, facilitate operation and maintenance file management and later traceability analysis, and provide data support for power station maintenance decisions.

Application scenarios cover electrical safety testing throughout the entire lifecycle of photovoltaic power plants. During the construction phase of the power station, it can be used for electrical system installation acceptance, testing whether cables, components, grounding devices, etc. meet safety standards, and controlling the construction quality from the source; In daily operation and maintenance, regular insulation and grounding testing is carried out to promptly identify potential safety hazards, intervene in maintenance in advance, and prevent safety accidents from occurring; After troubleshooting, it can be used for maintenance effectiveness verification to ensure that the fault is completely resolved and the electrical system is restored to a safe operating state. In addition, it can also be adapted for insulation and grounding detection of high-voltage electrical equipment in industrial production, power operation and maintenance, and other fields, with a wide range of applications.

Suzhou LAILX has been deeply involved in the field of photovoltaic electrical safety testing for many years, always taking it as its responsibility to safeguard the safety of power stations. The launch of LXH601 insulation grounding comprehensive tester effectively solves the pain points of traditional electrical detection equipment such as single function, low efficiency, and difficult fault location, providing comprehensive protection for the electrical safety of photovoltaic power plants. In the future, LAILX will continue to focus on the needs of photovoltaic safety operation and maintenance, increase research and development investment, and launch more high-performance and high reliability testing equipment to safeguard the safe, stable, and high-quality development of the global photovoltaic industry.
