As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time, and problems such as aging of cable insulation and corrosion failure of grounding devices can easily cause safety accidents such as leakage, short circuits, and lightning strikes, seriously threatening personnel safety and stable equipment operation. Traditional detection equipment has a single function and is cumbersome to operate. It requires the cooperation of multiple instruments to complete insulation, grounding, and other tests, resulting in low efficiency and high costs. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of photovoltaic electrical safety testing and has launched the LXH601 comprehensive insulation and grounding tester. With integrated design, high-precision testing, and intelligent operation, it provides a one-stop solution for the electrical safety of photovoltaic power plants. Multi functional comprehensive electrical appliance

LXH601 completely breaks the limitations of traditional devices' "one machine, one use" and achieves "one device, full item detection". The whole machine integrates eight core functions: insulation resistance testing, grounding resistance testing, conduction testing, voltage detection, polarity testing, Voc testing, Isc testing, and insulation fault location. It does not require frequent switching of equipment and wiring, and can complete comprehensive electrical safety testing of photovoltaic modules, inverters, combiner boxes, cable lines, grounding devices, etc. in one deployment. The efficiency of a single inspection is increased by more than 40%. In terms of insulation resistance testing, the equipment supports 0-1500V DC voltage detection, accurately adapting to the current mainstream 1500V high-voltage photovoltaic system, with a measurement accuracy of ± 5%; The grounding resistance test adopts the four pole method measurement technology, effectively eliminating the interference of soil resistance and lead resistance, with a measurement accuracy of ± 2%, ensuring the safety of the electrical system in all aspects.

The LXH601 is equipped with an intelligent insulation fault location module, which can accurately locate the insulation fault position in photovoltaic strings and cable lines. Through percentage value positioning technology, the specific location of the fault in the string is intuitively displayed in the intelligent photovoltaic APP, without the need for step-by-step troubleshooting, greatly reducing the troubleshooting time. The device has a built-in large capacity storage that can store thousands of sets of test data. It supports one click data export and automatic report generation, meeting the needs of power station operation and maintenance archives retention, third-party testing report issuance, and more. At the same time, equipped with a high-definition color touch screen, the operation interface is simple and intuitive, and beginners can quickly get started.

In terms of outdoor adaptation and safety design, LXH601 adopts an integrated portable design, with a compact and lightweight body, paired with a high-strength protective box, which is shockproof, waterproof, and dustproof. It can be easily carried to various outdoor photovoltaic power plants such as mountains, deserts, and rooftops. The equipment has overvoltage, overcurrent, and short-circuit protection functions, with a high insulation protection level to eliminate the risk of leakage; The high-voltage testing end adopts an anti electric shock design to ensure the safety of operators. In addition to photovoltaic power stations, LXH601 can also be widely used in power distribution networks, industrial plant electrical systems, new energy storage power stations, charging piles and other scenarios, becoming a versatile equipment for electrical safety testing in the entire industry.
