[0002] At present, in the power system, most of the armored removable AC enclosed switchgears used in high-voltage switchgear are equipped with a grounding knife shaft operating mechanism made of ∮25 round steel. The operating mechanism mainly has a shaft made of ∮25 round steel. Composition; the shaft of this mechanism is not easy to debug during the installation process, and it is not easy to change in different cabinet types and has low variability. Generally, the length of the shaft is between 1200mm-1350mm, so it increases the difficulty of carrying

Embodiment Construction
[0016] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:
[0017] as attached figure 1 — attached image 3 As shown, the present invention is a large shaft operating mechanism for switchgear grounding blades, which includes a shaft 1 with a rod-shaped structure. A structure connected by a plurality of shaft sleeves 3 is arranged between them.
[0018] Each of the shaft assemblies 2 is configured as a hollow tubular structure, and each shaft sleeve 3 is also configured as a hollow tubular structure, and the shaft sleeves 3 are configured to fit the ends of the two shaft assemblies 2 connected structure.
[0019] The multiple shaft assemblies 2 are the front shaft 4, the rea...

The invention provides a switch cabinet earthing switch main shaft operating mechanism, which is applied in the technical field of metal armoured movable-type high-voltage switch equipment. The switch cabinet earthing switch main shaft operating mechanism comprises a shaft (1) in a rod-shaped structure, wherein the shaft (1) is arranged into a structure composed by a plurality of shaft components (2); and the structures which are connected through a plurality of shaft sleeves (3) are formed between the shaft components (2). With the adoption of the switch cabinet earthing switch main shaft operating mechanism, the problem that the integral-type shaft is inconvenient to carry due to the fact that the shaft is too long can be reduced, and the working difficulty is reduced; and an intermediate shaft I and an intermediate shaft II are all made of hollow phi 36 round steel, so that not only is the processing and manufacturing cost lowered, but also the usability of the intermediate shafts is improved. With the adoption of the switch cabinet earthing switch main shaft operating mechanism provided by the invention, the labor can be saved in an operating process, and the operability is higher.
Description
technical field [0001] The invention belongs to the technical field of metal-clad removable high-voltage switchgear, and more specifically relates to a large-axis operating mechanism of a grounding blade of a switch cabinet. Background technique [0002] At present, in the power system, most of the armored removable AC enclosed switchgears used in high-voltage switchgear are equipped with a grounding knife shaft operating mechanism made of ∮25 round steel. The operating mechanism mainly has a shaft made of ∮25 round steel. Composition; the shaft of this mechanism is not easy to debug during the installation process, and it is not easy to change in different cabinet types and has low variability. The length of the general shaft is between 1200mm and 1350mm, which increases the difficulty of carrying. Because the size of the shaft is ∮25, the rotation stroke of the shaft itself is large during the operation of the large shaft, so that the operation process must use greater for...
