Description

Technical Field

[0001] The utility model relates to a ring network cabinet installation structure, in particular to a ring network cabinet wall hanging structure. Background Art

[0002] A ring main unit (RMU) is a type of high-voltage switchgear primarily used in power distribution systems. Its core function is to improve power supply reliability. RMUs come in a variety of styles, including common and unit types based on the gas tank structure; American and European styles based on the overall structure; solid-insulated, air-insulated, and SF6 gas-insulated types based on the insulation material; and indoor and outdoor types. RMUs can be categorized by installation method as either floor-standing or wall-mounted. Wall-mounted RMUs require a mounting mechanism to secure the RMU to a vertical surface.

[0003] Announcement No. CN214176572U records a wall-mounted ring network cabinet, including a fixed seat, a cabinet door, a protective cabinet and a fixed sleeve. A buffer plate is fixedly installed on the bottom of the ring network cabinet body, and a limit sleeve is fixedly installed on the bottom of the buffer plate. The fixed sleeve outside the limit sleeve is provided with a spring. The bottom end of the inner part of the ring network cabinet body is fixedly installed with a mounting base, and a buffer groove is fixedly provided on the mounting base. A fixing sleeve is fixedly installed on the back of the protective cabinet, a mounting plate is fixedly installed on the back of the fixing seat, and a fixing bolt is fixedly installed on the mounting plate. A wall is fixedly installed on one side of the mounting plate, and a sliding rod is fixedly installed on the top of the fixing seat between the mounting plate and the protective cabinet. The fixing sleeve is installed on the sliding rod through the provided sliding rod and the fixing sleeve, and the fixing sleeve is installed on the back of the protective cabinet.

[0004] This wall-mounted RMU simply slides a fixing sleeve onto the slide bar from top to bottom. This requires the RMU to be lifted to a point where the fixing sleeve is higher than the slide bar for the cabinet to fit. This method requires more headroom for taller RMUs, making it difficult to install in tight spaces. Furthermore, there's no locking mechanism between the fixing sleeve and the slide bar, allowing the RMU to slide vertically even after installation, resulting in poor stability. Utility Model Content

[0027] Through the implementation of the above technical solution, during assembly, the installation position is first determined, and the fixing operation of the ring network cabinet wall-mounted structure is carried out, specifically: by pulling and pulling the insertion rod 3, the position of the U-shaped plates 4 on the left and right sides is adjusted. After the position of the U-shaped plates 4 in the two mounting frames 1 is adjusted to the right, two connecting strips 2 are used to arrange the two mounting frames 1 symmetrically on the left and right, and then the expansion bolts are used to pass through the first countersunk holes 10 to fix the assembled ring network cabinet wall-mounted structure to the installation vertical surface. Then, the installation operation of the ring network cabinet is carried out, specifically: the four I-shaped blocks installed by bolts on the back of the ring network cabinet are inserted into the four first rectangular grooves 6 one by one, and then the ring network cabinet is moved downward so that the four I-shaped blocks are respectively inserted into the corresponding insertion gaps. After the insertion is in place, a locking block 7 is inserted into each socket. The inserted I-shaped block is limited by the locking block 7 to prevent it from being separated from the insertion gap due to external force. After the locking block 7 is inserted into the right, the plate body 8 is fixed in the second rectangular groove by the first bolt 9, so that the locking block 7 is fixed and cannot be pulled out.

[0028] The wall-mounted structure of the ring network cabinet has the following beneficial effects: 1. The installation width range can be expanded by setting the insertion rod 3; 2. The two mounting frames 1 installed upper and lower can enable a higher ring network cabinet to be stably installed, and the two mounting frames 1 can be quickly aligned through the connecting strip 2; 3. The I-block can be stably assembled into the insertion gap through the action of the locking block 7, the plate 8 and the first bolt 9, thereby improving the installation stability.
