[0002] With the rapid development of power electronics technology, backup power supplies have become indispensable emergency equipment in various applications. After a power outage, backup power supplies, combined with generator sets and control systems, form an independent emergency power supply system. However, backup power supplies are inoperative under normal conditions, necessitating regular power testing of the entire backup power system using power testing equipment to verify its ability to operate properly in an emergency. Regular testing of backup power supplies is essential in industries such as shipbuilding, aerospace, military, communications, solar photovoltaic, wind, thermal, and nuclear power, finance, coal, chemical, metal mining, and oil extraction.
[0003] In the existing technology, power supply detection equipment is often used to test the backup power supply. The power supply detection equipment mainly performs power load testing based on the principle of thermal resistance. Since the connection methods of emergency equipment are divided into star connection structure and triangle connection structure, common power supply detection equipment often needs to be equipped with a busbar structure that is compatible with the star connection structure or the triangle connection structure.
[0004] However, the busbar structure on common power supply detection equipment can only be adapted to a star connection structure or a triangle connection structure, which means that the busbar structure or the power supply detection equipment needs to be replaced when testing equipment with different connection structures, resulting in low availability of the power supply detection equipment. There is room for improvement. Utility Model Content
