Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a high-voltage switchgear structure. Background Technology

[0002] High-voltage switchgear, as a core piece of equipment in the power transmission and distribution system, is widely used in power plants, substations, industrial plants, and high-rise buildings. It primarily undertakes the functions of connecting, disconnecting, protecting, and monitoring power equipment. Internally, it integrates numerous precision electrical components such as circuit breakers, disconnectors, instrument transformers, and busbars. The stable operation of these components directly determines the reliability and security of the entire power supply system.

[0003] In actual use, the switch cabinet relies on the internal heat dissipation equipment and the heat dissipation mesh on the cabinet door to exchange heat with the outside. However, the heat dissipation mesh cannot block the humid air outside. Therefore, in some relatively humid environments, moisture can easily enter the cabinet from the heat dissipation mesh, causing the internal components to become damp and damaged. At the same time, the built-in heat dissipation device will generate heat itself, thus affecting the overall heat dissipation effect. Therefore, this application provides a high-voltage switchgear structure to meet the requirements. Utility Model Content

[0016] The driving pulley can drive the driven pulley to rotate via the transmission belt, which in turn can drive the driving rod and the driven rod to rotate simultaneously.

[0017] Optionally, the connecting component includes a rectangular frame, one side of which is fixedly connected to one side of the cabinet door, and a rectangular block is engaged with the inner wall of the rectangular frame, one side of which is fixedly connected to an L-shaped plate.

With the help of heat dissipation components, the entire heat dissipation equipment is placed externally, which can effectively avoid the situation where the heat dissipation equipment inside the cabinet affects the heat dissipation due to its own heat generation.

[0022] With the help of the connecting components, the heat dissipation components and cabinet doors can be disassembled and assembled, thereby allowing the heat dissipation components to be disassembled, maintained, or replaced. Furthermore, the detachable design of the heat dissipation components allows for the determination of whether to activate external heat dissipation equipment based on actual conditions.

[0042] Working principle like Figures 1-5 As shown, when in use, the sponge block 310 is placed inside the mounting frame 34, and the limiting round rod 311 is inserted into the limiting round hole 312. The rectangular ring clamp 33 is clamped to the rectangular ring clamp frame 32. At this time, the threaded clamp rod 39 is fixed to the first screw hole 36 and the second screw hole 38, so that the mounting frame 34 and the cabinet door 2 can be installed. At this time, the rectangular card block 51 is snapped into the rectangular card frame 52, and the threaded insert rod 55 is inserted and fixed into the first insertion hole 53 and the second insertion hole 54. The fixing nut 56 is fixed to the threaded insert rod 55. Start the drive motor 42, so that the drive rod 43 can drive the drive pulley 45 to rotate, which in turn drives the transmission belt 47 and the driven pulley 46 to rotate, which in turn drives the fan blade 48 to rotate, thereby enabling heat dissipation.
