Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a metal-enclosed ring network switch device. Background Art

[0002] Metal-enclosed ring mainframe switchgear (MMS) is a high-voltage electrical product that plays a key role in the generation, transmission, distribution, and conversion of power systems. This equipment typically includes components such as circuit breakers, disconnectors, load switches, operating mechanisms, transformers, and various protective devices. In some special scenarios, due to the high concentration of dust in the air, the MMS switchgear used in these environments generally uses sealed cabinets made of opaque metal for high strength. However, this cabinet prevents visibility of components such as the circuit breaker, disconnector, load switch, operating mechanism, and transformer within. Operators must open the cabinet to operate, allowing dust to easily enter, resulting in poor dust protection. Utility Model Content

[0005] The above technical solution can produce the following effects: the observation window is connected to the cabinet body via a slide rail assembly, making it easier to assemble and disassemble the observation window from the cabinet body. The slide rail assembly is composed of first slide rails arranged at the upper and lower ends of the observation window, and second slide rails arranged at the side ends of the observation window. These slide rails together form an opening for inserting the transparent window into the observation window position and fixing it in place. The side walls of the first and second slide rails are both provided with positioning portions to ensure that the transparent window is correctly positioned and fixed. The cabinet body can be sealed with the side walls of the transparent window to maintain a stable environment inside the cabinet. The transparent window is easy to assemble and disassemble, making it easier to observe the situation inside the cabinet. At the same time, the cabinet body's sealing and the observation window's stability are ensured, and the structure is simple.

[0006] The utility model is further provided with: the first slide rail has a sliding wall arranged perpendicularly to the cabinet body and a limiting wall parallel to the cabinet body, the sliding wall and the limiting wall are connected in an L-shape, the first slide rail at the upper end of the observation window and the first slide rail at the lower end are arranged opposite to each other, and the limiting wall at the upper end of the observation window and the limiting wall at the lower end cooperate to limit the transparent window.

[0007] The effect that can be produced by adopting the above technical scheme is: the first slide rail is set to be L-shaped, consisting of a sliding wall perpendicular to the cabinet body and a limiting wall parallel to the cabinet body. This structure not only provides a stable sliding space, but also enhances the ability to fix and position the transparent window. The upper and lower ends of the observation window are respectively provided with relative first slide rails, and their limiting walls cooperate with each other to effectively limit the transparent window and ensure the stability of the window in the vertical direction.

[0009] The effect produced by adopting the above technical solution is: the setting of the limiting convex edge can make the transparent window more stable after being fixed in the work station, less likely to shake, less likely to deviate from the work station, and improve the connection stability.

[0010] The utility model is further provided with: elastic arc-shaped protrusions are evenly distributed on the side walls of the limiting convex edge, the side walls of the limiting convex edge are arranged in a corrugated shape, and the transparent window is provided with arc-shaped grooves corresponding to the elastic arc-shaped protrusions and plugged therewith.
