The main switch can use either a permanent magnetic mechanism vacuum circuit breaker or a spring mechanism vacuum circuit breaker. The whole cabinet uses a combination of air insulation and sulfur hexafluoride gas compartment, which is suitable for power distribution automation. The structural characteristics of different types of high-voltage gas-filled cabinets are similar. They mainly use fixed structural technology and maintenance-free vacuum circuit breaker technology to replace the central low-oil circuit breaker with a limited number of operations; they use excellent performance sulfur hexafluoride gas insulation to replace air insulation, and no longer need to maintain and repair the working components and switchgear. At present, when the existing high-voltage gas-filled switchgear is connected to the external copper tube cable, the end of the copper tube is required to be stamped flat and punched with a mounting hole. At the same time, some gas-filled cabinet busbar outlets are located at the bottom of the cabinet. Due to the restrictions of the installation position and angle, the copper tube needs to be bent, which increases the difficulty of connecting the gas-filled cabinet with the external cable.

[0003] In the prior art, when switching busbars of high-voltage gas-filled switch cabinets, the structure is relatively fixed, and when installing busbars of different sizes, the adaptability is poor, and manual operation is required during installation, which is inconvenient to use.
