Description

Technical Field

[0001] This utility model relates to the field of insulation testing technology, specifically to an insulation testing tool for battery racks in energy storage cabinets. Background Technology

[0002] Insulation testing, acting as a "safety guardian" in the field of electrical safety, is a crucial line of defense for ensuring the stable operation of power systems and electronic equipment. In equipment such as energy storage cabinets, substations, and new energy vehicles, insulation performance directly affects equipment safety and the safety of personnel and property. If insulation materials age, become damp, or are damaged, it can easily lead to serious accidents such as leakage, short circuits, or even fires. Through professional insulation testing tools, key parameters such as equipment insulation resistance and leakage current can be accurately measured, allowing for the timely detection of potential insulation defects and providing data support for equipment maintenance and troubleshooting. From traditional hand-cranked megohmmeters to today's intelligent and portable testing equipment, insulation testing technology is constantly innovating, building a solid safety barrier for electrical equipment in a more efficient and accurate way, ensuring the flawless transmission and use of energy.

[0003] Against the backdrop of the rapid development of the energy storage industry, energy storage cabinets, as core equipment for energy storage and management, directly affect the safety and stability of system operation due to the insulation performance of their battery racks. Traditional insulation testing tools have significant limitations in application: First, most existing testing probes are designed with fixed spacing, making it difficult to adapt to the structural differences of battery racks of different specifications, such as the narrow testing space of dense battery racks and the wide-spacing testing requirements of large battery racks, resulting in some areas being unable to be effectively tested; Second, the probe and testing equipment are connected in an integrated or non-detachable manner, so once the probe is damaged, the entire unit must be replaced, resulting in high maintenance costs and time consumption; Third, most testing tools lack flexible adjustment structures, making it impossible to deeply test the complex and narrow spaces inside the energy storage cabinet (such as gaps between battery packs and corner joints), easily creating blind spots.
