The working principle of the vacuum arc-extinguishing chamber transfer conveying disc with wide application range is as follows:

a vacuum arc-extinguishing chamber (not shown) is inserted into the transfer chassis 10; then the four limit cams 32 are synchronously and rotationally arranged, so that the vacuum arc-extinguishing chamber (not shown) is limited by the four limit cams 32, and the vacuum arc-extinguishing chamber (not shown) has the characteristics that the larger the diameter is, the lower the height is, the smaller the diameter is and the higher the height is, so that the technical scheme well meets the characteristics and is suitable for vacuum arc-extinguishing chambers (not shown) with different sizes and specifications;

meanwhile, the existence of the one-way limiting device ensures that the vacuum arc-extinguishing chamber (not shown) cannot move after being limited, thereby facilitating subsequent transportation and detection;

due to the existence of the classification mark circle 40, the specification of the vacuum arc-extinguishing chamber (not shown) can be easily distinguished subsequently, and the management is convenient.
