As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments such as sun exposure, rain, sandstorms, and humidity for a long time. The insulation layer of the cables is prone to aging and damage, and the grounding devices are prone to corrosion and failure, which can lead to safety accidents such as leakage, electric shock, short circuit, and lightning strikes, seriously threatening personnel safety and equipment stable operation. Traditional testing equipment has pain points such as single functionality, cumbersome operation, weak anti-interference ability, and insufficient accuracy. It requires carrying multiple instruments back and forth for operation, resulting in low detection efficiency and poor data reliability. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) is deeply engaged in the field of photovoltaic electrical safety testing, and has launched the LXH601 comprehensive insulation and grounding tester. With integrated multifunctional integration, high-precision testing, intelligent operation, and strong anti-interference ability, it provides a one-stop solution to the problem of insulation and grounding safety testing in photovoltaic power plants, and builds a solid defense line for photovoltaic electrical safety. Safety comprehensive tester

The core innovation of LXH601 lies in breaking the limitation of "one machine, one use" of traditional equipment, and integrating eight core functions such as insulation resistance testing, grounding resistance testing, conduction testing, voltage detection, polarity testing, Voc/Lsc testing, and insulation fault location. It does not require frequent switching of equipment and wiring, and can complete multiple key safety checks in one operation, completely solving the problem of operation and maintenance personnel carrying multiple instruments and repeated wiring. The efficiency of a single inspection has been improved by more than 40%. In the traditional detection mode, insulation testing requires an insulation shake meter, grounding testing requires a grounding resistance meter, and conductivity testing requires a multimeter, which has multiple equipment, complex wiring, and is time-consuming and labor-intensive; The LXH601 device can cover all scene security testing needs, significantly reducing equipment procurement and operation costs, simplifying testing processes, and improving operation and maintenance efficiency.

In terms of detection accuracy and reliability, LXH601 has reached the industry-leading level. The insulation resistance test range covers 0-10G Ω, and the test voltage can be selected from 500V/1000V/2500V. It is suitable for insulation testing needs of different high-voltage equipment such as photovoltaic modules, cables, inverters, and combiner boxes, and accurately detects insulation layer aging, damage, moisture and other issues. The grounding resistance test adopts the four pole method precise measurement technology, with a range of 0-200 Ω, which can effectively eliminate soil resistance and lead resistance interference, accurately detect faults such as corrosion, fracture, and poor contact of the grounding device, ensure the reliable conduction of the grounding system, and provide effective lightning protection and leakage protection for equipment and personnel. The device is equipped with a high-precision data acquisition module and intelligent filtering algorithm, which can effectively resist outdoor electromagnetic interference and voltage fluctuations. The detection data is stable, reliable, and highly repetitive, providing accurate data support for safety assessment.

Intelligent operation and user-friendly design make LXH601 suitable for complex outdoor work scenarios. The whole machine adopts an industrial grade integrated design, with a sturdy and durable body that is dustproof and waterproof, and can adapt to harsh outdoor environments such as high temperature, low temperature, humidity, and dust; Lightweight and compact in size, paired with a dedicated portable bag, it can be easily carried by a single person to various power plant scenarios such as mountains, rooftops, and deserts. The operation interface adopts a high-definition LCD display screen, with simple and intuitive Chinese menus and a one click detection mode, which can be quickly mastered without professional training; Supporting bipolar mode detection, it can simultaneously measure the insulation resistance of the positive and negative poles of the circuit to ground, accurately evaluating the insulation status of the equipment; Equipped with automatic polarity recognition and fault sound and light alarm functions, it can promptly alert operation and maintenance personnel when detecting abnormalities, avoiding the expansion of safety accidents. In addition, the device has a built-in large capacity storage that can store more than 500 sets of test data. It supports one click data export, printing, and cloud storage. Paired with dedicated data management software, it can generate professional testing reports, achieve traceability and analysis of testing data, and assist in the digital upgrade of operation and maintenance management.

The full scene adaptation and safety protection capabilities make LXH601 the core equipment for safe operation and maintenance of photovoltaic power plants. The equipment is widely used in scenarios such as completion acceptance of photovoltaic power plants, daily operation and maintenance inspections, fault diagnosis, and regular safety assessments. It can comprehensively detect key safety indicators such as component insulation performance, cable insulation status, grounding system reliability, and equipment conductivity, accurately locate insulation fault points and poor grounding locations, assist operation and maintenance personnel in rapid maintenance and replacement, reduce system downtime, and ensure stable operation of the power plant. At the same time, LXH601 is suitable for electrical safety testing scenarios such as industrial high-voltage equipment, power lines, and new energy storage systems, providing reliable guarantees for the safe operation of electrical equipment in multiple industries.

Suzhou LAILX always adheres to the development concept of "safety first, precise protection". The launch of LXH601 insulation grounding comprehensive tester accurately responds to the core needs of electrical safety testing in the photovoltaic industry, providing efficient and reliable solutions for the safe operation and maintenance of power plants. In the future, LAILX will continue to focus on the field of photovoltaic electrical safety, increase research and development investment, continuously optimize product performance, and launch more high-precision, intelligent, and portable safety testing equipment to help the photovoltaic industry develop safely, stably, and efficiently, and to safeguard the clean energy industry.
