Photovoltaic power plants are exposed to complex outdoor environments for a long time, and are affected by factors such as humidity, dust, high temperature, and ultraviolet radiation. The electrical system is prone to insulation performance degradation, poor grounding, and line damage, which can lead to system leakage and power loss, as well as safety accidents such as electric shock and fire, seriously threatening the life safety of power plant operation and maintenance personnel and the stable operation of equipment. Therefore, regularly conducting electrical safety inspections such as insulation and grounding is the core link of photovoltaic power station operation and maintenance management. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the needs of photovoltaic electrical safety testing and has ingeniously created the LXH601 insulation grounding comprehensive tester, which integrates multiple electrical safety testing functions to achieve one-stop accurate detection and fault location, providing protection for the electrical safety of photovoltaic power plants.

LXH601 is a professional level electrical safety comprehensive testing equipment for photovoltaic systems. The entire machine is designed to meet the actual operation and maintenance needs of photovoltaic power stations, strictly following international measurement standards such as IEC/EN61557 and IEC62446. It has comprehensive functions such as voltage and current testing, conductor continuity testing, grounding resistance testing, insulation fault location, polarity testing, Voc and Isc testing, etc. One device can complete the electrical safety project testing of photovoltaic systems, bidding farewell to the tedious traditional use of multiple devices and greatly improving testing efficiency. Its core testing performance is industry-leading, with insulation testing voltage up to 1500V, meeting the current testing needs of 1500V high-voltage photovoltaic systems. It supports two testing modes: DUAL dual-mode and TIMER timed mode. DUAL mode can sequentially measure the insulation resistance of the positive and negative poles of photovoltaic modules to ground, and complete bipolar testing with one click; TIMER mode allows customization of testing time, adapting to testing requirements of different standards and scenarios, and is flexible and efficient.

Accurate fault location is the core technological advantage of LXH601. In response to the industry pain points of hidden and difficult troubleshooting of insulation faults in photovoltaic power plants, the equipment is equipped with professional insulation fault positioning functions, which can accurately locate insulation fault points caused by cable damage, junction box water leakage, component aging, line wear, etc., without the need for operation and maintenance personnel to investigate them one by one, greatly reducing the time for fault troubleshooting and minimizing system downtime losses. The grounding resistance test adopts advanced measurement technology, which can accurately measure the grounding resistance value of the photovoltaic system grounding device and SPD grounding rod, ensuring that the grounding system meets safety standards and effectively releases lightning and leakage currents. The continuity test of conductors can reliably detect the protective conductors and equipotential conductors of photovoltaic equipment, ensuring firm electrical connections and avoiding safety hazards caused by poor contact. At the same time, the device can synchronously test Voc (open circuit voltage) and Isc (short circuit current), and comprehensively evaluate the operating status of the photovoltaic system based on electrical safety testing data.

In terms of operational convenience and outdoor adaptability, LXH601 performs excellently. The device adopts a handheld integrated design, with a compact and lightweight body, matched with a high-strength protective shell, and has good dustproof, waterproof, and anti drop performance, which can adapt to the complex outdoor environment of power stations. Equipped with a high-definition LCD display screen, the data display is clear and intuitive, with a bilingual operation interface in Chinese and English. The menu design is simple and easy to understand, paired with physical button operation, responsive, and can be easily operated even when wearing gloves outdoors. Equipped with a large capacity rechargeable lithium battery, it supports long-term outdoor continuous testing without the need for an external power source, solving the problem of outdoor power supply. The device has automatic data storage function, which can store thousands of sets of test data, support data query, export, and printing, facilitate the generation of standardized testing reports, and achieve traceability of testing data. At the same time, the equipment has comprehensive safety protection functions, such as automatic discharge, overcurrent protection, and misoperation reminder during high-voltage testing, to ensure the safety of the testing personnel.

From the perspective of application scenarios, the LXH601 insulation grounding comprehensive tester covers the electrical safety testing requirements of the entire lifecycle of photovoltaic power plants. During the construction phase of the power station, it can be used for electrical installation acceptance testing to ensure that the construction quality of grounding, insulation, etc. meets the standards and avoid safety hazards in the later stage. Suzhou Laikesi New Energy Technology Co., Ltd; During the operation and maintenance phase of the power station, regular preventive testing can be carried out to promptly identify potential issues such as insulation aging and poor grounding, and to repair and handle them in advance to prevent safety accidents from occurring; During the maintenance of power plant faults, the electrical fault point can be quickly located, providing accurate basis for fault repair and shortening maintenance time. In addition, the equipment is also suitable for insulation and grounding testing of other power systems and electrical equipment, with strong universality. It is an essential testing tool for photovoltaic enterprises, power operation and maintenance units, and third-party testing institutions. Suzhou Laikesi New Energy Technology Co., Ltd.
