[0002] The main function of switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components of switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices. Switchgear is suitable for various applications such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings. Secondary components such as fuses and terminals are typically installed inside the instrument room within the switchgear.

[0003] Existing rotary terminal mounting beams are generally fixed installation structures, such as Figure 1 As shown, after terminals are assembled on the terminal beams, adjacent terminal beams interfere with each other, making it inconvenient to install and maintain secondary lines. Furthermore, the installation of the terminal beams requires bolts, which are typically installed separately and are prone to falling off during maintenance, making them difficult to locate. To address this issue, we propose a high-voltage switchgear with rotatable terminal mounting beams. Utility Model Content
