During the movement of the moving frame, the pin is inserted into the positioning hole below and the plug hole on the surface of the movable block, so that the height difference of the front pulley during the movement process can be compensated, so as to avoid the situation that the moving frame is tilted due to the height change after the front pulley moves out of the inner cavity of the pulley groove, thereby ensuring the stability of the moving frame.

Description

Technical Field

[0001] The utility model relates to the technical field of solid insulation cabinets, in particular to a solid insulation switch cabinet. Background Art

[0002] Solid insulation cabinets use solid insulation materials directly applied to high-voltage equipment to replace traditional gas insulation materials (such as SF6, N2, etc.), thus forming a new type of insulation structure. Solid insulation materials have good insulation properties, mechanical strength, explosion-proof properties and other advantages. Therefore, solid insulation cabinets have higher reliability and better environmental protection performance. Solid insulation cabinets are widely used in power transmission and distribution systems.

[0003] In a solid insulated switchgear, electrical equipment is generally fixed directly inside the cabinet by bolts. Since the space inside the insulation cabinet is often limited, especially when the equipment is closely arranged, this space limitation makes it difficult for maintenance personnel to flexibly move and operate inside, thereby increasing the difficulty of maintenance. Some electrical equipment may be installed in difficult-to-access locations, such as deep inside or in a corner of the insulation cabinet. These locations may require disassembly of other equipment to reach, thereby increasing the complexity of maintenance. For this reason, a solid insulated switchgear is proposed.
