As a high-voltage direct current electrical system, photovoltaic power plants are exposed to the outdoors for a long time, experiencing wind, sun, rain, snow, frost, sand and dust erosion. The cable insulation layer is prone to aging and damage, and the grounding device is prone to corrosion and failure, which can lead to safety accidents such as leakage, electric shock, short circuit, and lightning strikes. This not only threatens the safety of power plant personnel, but also causes equipment damage, power generation interruption, and huge economic losses. Insulation performance and grounding reliability are the two core cornerstones of electrical safety in photovoltaic systems. Traditional testing tools have a single function, are cumbersome to operate, and have weak anti-interference capabilities. They require carrying multiple devices back and forth for operation, resulting in low efficiency and insufficient data accuracy, making it difficult to meet the safety testing needs of all scenarios. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has been deeply involved in the field of new energy testing for many years. It has launched the LXH601 comprehensive insulation and grounding tester, which provides a one-stop solution for electrical safety testing of photovoltaic power plants with integrated multifunctional integration, high-precision testing, intelligent operation, and portable design, and strengthens the electrical safety defense line of photovoltaic systems. Multi functional comprehensive electrical appliance

LXH601 breaks the limitations of traditional testing equipment with "one machine, one use" and integrates eight core functions: insulation resistance testing, grounding resistance testing, equipotential continuity testing, AC/DC voltage testing, polarity testing, Voc testing, Lsc testing, insulation fault location. One device can complete comprehensive electrical safety testing of photovoltaic modules, inverters, combiner boxes, cable lines, grounding devices, etc. without frequent switching of equipment and wiring, completely solving the problem of operation and maintenance personnel carrying multiple instruments to and from work. The efficiency of a single inspection is increased 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 quickly lock the location of insulation damage and leakage, greatly reducing the troubleshooting time.

High precision detection technology ensures accurate and reliable data, suitable for the detection needs of photovoltaic high-voltage systems. The LXH601 insulation resistance test range covers 0.01M Ω to 10G Ω, and the test voltage can be selected from 500V/1000V/1500V, accurately adapting to the insulation detection of photovoltaic 1500V high-voltage systems; The grounding resistance test range is 0.01 Ω to 1000 Ω, with an accuracy of ± 2% rdg ± 0.1 Ω. It can accurately measure the grounding resistance of the grounding device to ensure grounding reliability. The equipment adopts anti-interference design and has good electromagnetic compatibility. It can stably measure in the dense electromagnetic environment of power plants, and the data accuracy is not affected by interference. Equipped with a high-definition LCD backlit large screen, the numerical values are clearly visible in strong light and dark environments. It supports data locking, automatic shutdown, and low power prompt functions, making operation convenient and reading intuitive.
Extremely portable and durable design, suitable for complex outdoor work scenarios. The LXH601 machine adopts a lightweight structural design, with a compact and portable body, and is equipped with a high-strength protective box. It can be easily carried by a single person to complex work scenarios such as mountains, rooftops, and wilderness. The equipment casing is made of high-strength engineering plastic and has an IP54 dustproof and waterproof rating, which can adapt to harsh environments such as high temperature, low temperature, humidity, and sand and dust. It is stable and reliable for long-term outdoor use. Equipped with a large capacity rechargeable battery, it has a long battery life and supports both AC and DC, meeting the needs of all day outdoor inspections. The layout of the operation buttons is reasonable, the functional identification is clear, and it supports one click testing, data storage, and query. Novices can quickly get started and operate without professional training.

Intelligent data management and security protection design enhance detection standardization and job security. LXH601 can store thousands of sets of test data and support one click export of data to the PC end. It is equipped with professional analysis software to achieve deep data analysis and automatic report generation, making it easy to trace and archive data and meet the standardized management needs of power plant operation and maintenance. The equipment has overload protection, automatic discharge, and double insulation protection functions. After testing is completed, it will automatically discharge to avoid residual voltage injuries and ensure the safety of operators. Widely used in daily operation and maintenance, regular maintenance, fault diagnosis, acceptance testing and other scenarios of photovoltaic power plants, while adapting to insulation and grounding safety testing in power systems, industrial electrical, building electrical and other fields, providing reliable guarantees for the safe operation of various electrical systems.

With core advantages such as integrated integration, high-precision detection, portability, durability, and intelligent safety, LXH601 has been highly recognized by the industry since its launch and has become the preferred equipment for photovoltaic electrical safety testing. Suzhou LAILX always adheres to the concept of "safety first, technological innovation, and quality first", relying on a sound research and development system, strict quality control, and professional after-sales service to provide customers with high-quality electrical safety testing solutions.
