Description

technical field [0001] The invention relates to the technical field of vacuum load switches, in particular to an operating mechanism of a modularized vacuum load switch-fuse combined electric appliance. Background technique [0002] Vacuum load switches are suitable for power distribution systems such as industrial and mining enterprises, high-rise buildings, residential quarters, schools and box-type substations, and the structure is relatively complicated. Commonly used vacuum load switches are generally relatively large in size, causing the power distribution cabinet to take up too much space, and has a complicated operating mechanism. The speed of closing and opening is not fast enough, and the operation is cumbersome. If the operator is not skilled in the operation, it will lead to operational errors. , the operation is inflexible, the installation and maintenance workload is heavy, and the equipment failure rate is high; moreover, the holding device of the current vacu...
