Description

Technical Field

[0001] This utility model relates to the field of ring main unit technology, and in particular to an outdoor ring main unit with a protective structure. Background Technology

[0002] A ring main unit (RNB) is an electrical device consisting of a group of high-voltage switchgear housed in a metal or non-metal insulated cabinet or assembled into a modular ring network power supply unit. RNBs are composed of current displays, observation windows, and the cabinet itself. Based on the main insulation medium, RNBs can be classified into air-insulated RNBs and SF6 gas-insulated RNBs; composite-insulated RNBs using solid insulation materials have also emerged. Based on the cabinet structure, RNBs are classified into three types: bay-type, common-enclosure type, and a hybrid bay + common-enclosure type. Their core components utilize load switches and fuses, offering advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. Their main function is to provide a clear disconnection point for the line during high-voltage testing or maintenance. They are widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] However, existing outdoor ring main units usually have a control panel on the outside of the cabinet so that the control panel can control or adjust the inside of the ring main unit. However, since outdoor ring main units are used outdoors, the control panel is exposed and easily scratched, which can cause the control keys on the control panel to malfunction and make it impossible to send control commands to the inside of the ring main unit.

Detailed Implementation

[0044] This utility model provides an outdoor ring main unit with a protective structure to solve the technical problem that existing outdoor ring main units are used outdoors, and the control panel is exposed and easily scratched, causing the control keys on the control panel to malfunction and making it impossible to send control commands to the inside of the ring main unit.

[0045] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0046] Example 1

[0047] Please see Figures 1 to 4 , Figure 1 This is a structural diagram of an outdoor ring main unit with a protective structure, provided for an embodiment of the present utility model.

[0048] This utility model provides an outdoor ring main unit with a protective structure, including a ring main unit cabinet 1 and a control panel provided on one side of the ring main unit cabinet 1; a protective component 2 is provided around the control panel; the protective component 2 includes a slide rail 211 and a protective shell 212; slide rails 211 are provided on both the left and right sides of the control panel; the protective shell 212 and the slide rails 211 are slidably connected; a buffer component 3 is provided on the inner side of the protective shell 212.

[0049] It should be noted that a control panel is located on one side of the ring main unit cabinet 1. To prevent the control panel from being scratched, dusty, or splashed with water, a protective component 2 is installed around the control panel to protect it.

[0050] In practical implementation, two vertical slide rails 211 are respectively installed on the left and right sides of the control panel, and a protective shell 212 is slidably connected to the inside of the slide rails 211. The left and right sides of the protective shell 212 are L-shaped, and the L-shaped sides slide inside the slide rails 211. The protective shell 212 is mainly used to protect the control panel. When it is necessary to input information on the control panel, the protective shell 212 can be pushed upward along the slide rails 211 to expose the control panel. When it is not necessary to input information on the control panel, the protective shell 212 can be moved downward along the slide rails 211 to completely cover the control panel and protect it.

[0051] Specifically, when the ring main unit is subjected to an impact, in order to prevent the control panel from being impacted, a buffer component 3 can be installed inside the protective shell 212 to further buffer the impact force and reduce the impact on the control panel.

[0052] Example 2

[0053] Please see Figures 1 to 4 , Figure 1 This is a structural diagram of an outdoor ring main unit with a protective structure, provided for an embodiment of the present utility model.

[0054] This utility model provides an outdoor ring main unit with a protective structure. A handle 213 is provided on the side of the protective shell 212 away from the ring main unit body 1. A pad 214 is slidably connected to the inner bottom of the slide rail 211; a first spring 215 is provided between the pad 214 and the slide rail 211; one end of the first spring 215 is fixedly connected to the inner bottom wall of the slide rail 211, and the other end is fixedly connected to the bottom of the pad 214. A slot is provided on one side of the slide rail 211; a lever 216 adapted to the slot is rotatably connected to one side of the protective shell 212 via a fixed base; the lever 216 engages with the slot; a second spring 217 is provided between the lever 216 and the protective shell 212; one end of the second spring 217 is fixedly connected to the inner side of the lever 216, and the other end is fixedly connected to the outer wall of the protective shell 212.

[0055] It should be noted that the protective shell 212 is equipped with a handle 213, which makes it easy for workers to slide the protective shell 212 upwards or downwards. A pad 214 is slidably connected to the bottom inner side of the slide rail 211, and a first spring 215 is provided between the pad 214 and the bottom inner wall of the slide rail 211. When the protective shell 212 slides downwards, the first spring 215 can further cushion the protective shell 212, preventing the protective shell 212 from sliding off the slide rail 211 due to excessive impact when sliding directly downwards.

[0056] A slot is provided on one side of the slide rail 211. The protective shell 212 is rotatably connected to a lever 216 that matches the slot via a fixed base on the side near the slot. The lever 216 engages with the slot. When it is necessary to slide the protective shell 212, the lever 216 is first moved away from the slot, and the protective shell 212 can be slid. When it is not necessary to slide the protective shell 212, the lever 216 is inserted into the slot to fix the protective shell 212, preventing the protective shell 212 from being arbitrarily slid by others, or preventing the protective shell 212 from sliding upward when it is impacted, which would damage the control panel.

[0057] A second spring 217 is provided between the lever 216 and the protective shell 212, so that when the lever 216 is within the slot range, the pulling force of the second spring 217 will automatically engage the lever 216 with the slot.

[0058] In practice, by moving the lever 216, one end of the lever 216 is no longer engaged with the slot, and the protective shell 212 slides along the track of the slide rail 211 via the handle 213. Under the action of the pad 214 and the first spring 215, the protective shell 212 is cushioned from falling. Conversely, when the protective shell 212 is slid, the force of the second spring causes the lever 216 to automatically engage with the slot when the lever 216 passes through the slot, thereby achieving the effect of quickly fixing and removing the protective shell 212.

[0059] Example 3

[0060] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a buffer component provided in an embodiment of the present utility model.

[0061] This utility model provides an outdoor ring main unit with a protective structure. The buffer assembly 3 includes fixed slide rails 311 and fixing blocks 318. Multiple fixed slide rails 311 and multiple fixing blocks 318 are provided on the inner wall of the protective shell 212. Preferably, there are four fixed slide rails 311 and two fixing blocks 318. Each fixed slide rail 311 has a slider 312 slidably connected inside; each slider 312 has a connecting rod 313 slidably connected inside; the extension end of the connecting rod 313 extends outward through the slider 312; a third spring 314 is provided between the extension end of the connecting rod 313 and the slider 312; the third spring 314 is sleeved on the outer wall of the extension end of the connecting rod 313 and fixedly connected to the extension end of the connecting rod 313, and its other end is fixedly connected to one side of the slider 312. A connecting block 315 is rotatably connected between two opposing connecting rods 313 via a shaft. One end of the connecting block 315 is fixedly connected to a connecting post 316; the other end of the connecting post 316 is fixedly connected to a buffer plate 317. A fourth spring 319 is provided between the other end of the connecting block 315 and the fixing block 318; one end of the fourth spring 319 is fixedly connected to the other end of the connecting block 315, and the other end is fixedly connected to the fixing block 318.

[0062] It should be noted that, as Figure 5 As shown, the buffer assembly 3 includes four fixed slide rails 311 and two fixed blocks 318. The four fixed slide rails 311 are respectively arranged inside the protective shell 212 in a T-shape with the shell 212. A slider 312 is slidably connected to the inner side of each of the four fixed slide rails 311. A connecting rod 313 is slidably connected inside each slider 312. One end of the connecting rod 313 extends outward through the slider 312, serving as an extension end. The other end is rotatably connected to another connecting rod 313 via a shaft, serving as a connection end. Specifically, a third spring 314 is sleeved on the outer wall of the extension end of the connecting rod 313. One end of the third spring 314 is fixedly connected to the end point of the extension end, and the other end of the third spring 314 is fixedly connected to the slider 312. A connecting block 315 is rotatably connected to the connection ends of two opposing connecting rods 313 via a shaft.

[0063] One end of the connecting block 315 is fixedly connected to one end of the connecting post 316, and the other end of the connecting block 315 is fixedly connected to the fixing block 318 through the fourth spring 319, while the other end of the connecting post 316 is fixedly connected to the buffer plate 317.

[0064] Specifically, a fixing block 318 is provided between two parallel fixed slide rails 311.

[0065] In practical implementation, when the protective shell 212 is impacted, the buffer plate 317, with the assistance of the connecting block 315 and the fourth spring 319, performs the first stage of buffering against the impact force. However, when the connecting block 315 performs oscillation buffering, the connecting rod 313 swings left and right, thereby driving the slider 312 to slide inside the fixed slide rail 311, causing the third spring 314 to continuously extend and retract between the connecting rod 313 and the slider 312, achieving the effect of the second stage of buffering against the impact force.

[0066] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, devices, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0067] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
