As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments such as sun exposure, rain, humidity, and sandstorms for a long time. The insulation layer of the cables is prone to aging and damage, the junction box is prone to water leakage, and the grounding device is prone to corrosion and failure, which can lead to 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 insulation and grounding detection equipment has a single function, complicated operation, and weak anti-interference ability. It requires carrying multiple instruments back and forth for operation, frequently switching equipment and wiring. This not only results in low detection efficiency and high labor costs, but also easily leads to detection errors due to operational errors, making it difficult to meet the electrical safety detection needs of photovoltaic power plants in all scenarios. To solve the pain points in the industry, Laix New Energy Technology Co., Ltd. (LAILX) in Suzhou has been deeply involved in the field of new energy safety testing. It has launched the LXH601 comprehensive insulation and grounding tester, which features integrated design, high-precision detection performance, and intelligent operation experience. It provides a one-stop solution to the insulation and grounding safety testing problems of photovoltaic power plants, safeguarding the safe and efficient development of the photovoltaic industry.

LXH601 breaks the limitations of traditional equipment's "one machine, one use" approach and achieves multi-functional integration. It integrates more than ten core functions such as insulation resistance testing, grounding resistance testing, conductivity testing, voltage detection, polarity testing, Voc/Lsc testing, and insulation fault location into one device. One device can complete the full range of electrical safety testing for photovoltaic power plant components, inverters, combiner boxes, cable lines, grounding devices, etc., without the need for frequent switching of equipment and wiring. Multiple key data can be obtained in one operation, greatly improving the efficiency of operation and maintenance testing, reducing equipment procurement costs and operational complexity. The equipment is designed specifically for the 1500V high-voltage system of photovoltaic power plants, suitable for all types of power plants such as centralized, distributed, and household photovoltaics, and can meet the electrical safety testing needs of different scales and scenarios. Its versatility and adaptability are industry-leading.
In terms of detection accuracy and stability, LXH601 adopts high-precision detection chips and anti-interference circuit design. The insulation resistance testing range is wide and the accuracy is high, which can accurately detect the insulation performance of cables, components, inverters and other equipment, and timely detect hidden dangers such as insulation aging and damage; The grounding resistance test adopts the four pole method for measurement, effectively eliminating the influence of contact resistance.

The test data is accurate and reliable, which can accurately evaluate the grounding performance of the grounding device, ensure that the grounding system can quickly conduct current in case of faults, and prevent the risk of electric shock and lightning strikes. At the same time, the equipment has a 200mA protective conductor continuity testing function, which can verify the reliability of the protective grounding conductor connection and further ensure the safety of the electrical system; Built in intelligent fault location algorithm can accurately locate the location of insulation faults, helping operation and maintenance personnel quickly troubleshoot faults, shorten maintenance time, and reduce operation and maintenance costs.

In terms of operability and portability, LXH601 fully meets the testing needs of outdoor photovoltaic power plants. The whole machine adopts a lightweight design, compact size, and is equipped with a high-strength protective chassis, which is shockproof, dustproof, and waterproof, making it easy to carry and transport. One person can easily complete equipment handling and operation. The device is equipped with a high-definition LCD display screen, a Chinese operation interface, simple and intuitive menus, simplified operation processes, and can be quickly mastered without professional technical background. It supports one click start detection, real-time data display, automatic result judgment, sound and light alarm prompts, and other functions. The detection process is efficient and convenient, greatly reducing the difficulty of operation. In addition, LXH601 supports real-time data storage, historical record query, report export, and USB data transmission. It can be integrated with the photovoltaic operation and maintenance cloud platform to achieve remote uploading, analysis, and management of detection data, helping photovoltaic power plants achieve intelligent and refined operation and maintenance, and improving the level of power plant safety management.

Since its launch, the LXH601 insulation grounding comprehensive tester has been widely used in major photovoltaic power stations, power operation and maintenance enterprises, and third-party testing institutions due to its core advantages of integrated integration, high precision, strong portability, and easy operation. It has become the preferred equipment for photovoltaic electrical safety testing, effectively preventing electrical safety accidents and ensuring the long-term stable operation of photovoltaic power stations. In the future, LAILX in Suzhou will continue to focus on innovation in photovoltaic electrical safety testing technology, continuously optimize product performance, and provide professional technology and high-quality products to safeguard the safe and healthy development of the photovoltaic industry.
