The operation mechanism comprises a framework, wherein an energy storage motor, a switch-on spring, a switch-off tripping apparatus, an energy storage maintenance apparatus, an interlocking apparatus, a counting apparatus and a protection apparatus are arranged in the framework; the energy storage motor adopts a manual and automatic integrated energy storage motor; the framework comprises a first metal plate, a second metal plate and connecting rods; multiple connecting blocks are provided; and the first metal plate and the second metal plate are connected through the multiple connecting rods.

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...

[0002] Vacuum load switch is 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 vacuum load switch is mostly in the form of a half shaft, which leads to easy wear and tear of some parts and reduces the service life, while the complicated operating mechanism It also further increases the maintenance workload
