Description

Technical Field

[0001] This utility model relates to the field of busbar protection technology, specifically a common-enclosed busbar protection device. Background Technology

[0002] Busbars are used to transmit electrical energy and are products with the ability to collect and distribute power. During the installation of busbars, busbar trunking is generally used to collect and store busbars side by side to realize the arrangement of busbars, thereby reducing the chaos during busbar wiring and ensuring normal power distribution. A common-enclosed busbar is a metal-enclosed busbar in which the three-phase busbar conductors are enclosed in the same metal shell. It is mainly used in power plants, industrial and mining enterprises, etc., and is responsible for the electrical connection between generator and main transformer, transformer and high-voltage distribution cabinet, and main circuit of high-voltage equipment. The patent with publication number CN217159215U discloses a common-enclosure busbar trunking. Through the set connection mechanism, when the busbar needs to be inspected, the lower protective plate can be separated from the upper protective plate more conveniently and quickly, saving the user's inspection time and making the inspection more efficient. Although the above-mentioned busbar trunking is convenient for busbar inspection, in actual use, the busbars are generally tightly arranged in the busbar trunking. However, the lack of protective components in the busbar trunking causes close contact between adjacent busbars, which makes it easy to scratch during inspection, thereby causing damage to the busbars and affecting the practicality of the busbar trunking.

[0003] Therefore, this utility model provides a common enclosure busbar protection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a common-enclosure busbar protection device to solve the problems mentioned in the background art. This utility model provides dual protection through a protective top plate and an auxiliary top plate, and the three cable trays are relatively independent, so they will not affect each other during maintenance, thus preventing damage to the busbar. It can also achieve good heat dissipation, preventing the busbar from overheating and causing damage. The first elastic telescopic rod can be adjusted according to the busbar to ensure the fixing effect of the busbar, and after the busbar is squeezed, the length of the first elastic telescopic rod can be fixed to ensure the stability of the busbar.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a common-enclosed busbar protection device, comprising a protective shell, three cable trays inside the protective shell, a protective top plate fixedly attached to the top of the protective shell, an auxiliary top plate fixedly attached to the cable trays, a protective inner plate fixed inside the cable trays, a plurality of first elastic telescopic rods installed on one side of the protective inner plate, a fixing structure installed inside the first elastic telescopic rods, a heat-conducting structure installed inside the cable trays, and a heat dissipation structure installed inside the protective shell, the heat dissipation structure corresponding to the heat-conducting structure.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a common enclosure busbar protection device, including a protective shell 1, three cable trays 3 are provided inside the protective shell 1, a protective top plate 2 is snapped and fixed to the top of the protective shell 1, an auxiliary top plate 8 is snapped and fixed inside the cable trays 3, a protective inner plate 9 is fixed inside the cable trays 3, a plurality of first elastic telescopic rods 13 are installed on one side of the protective inner plate 9, a fixing structure is installed inside the first elastic telescopic rods 13, a heat-conducting structure is installed inside the cable trays 3, and a heat dissipation structure is installed inside the protective shell 1, with the heat dissipation structure corresponding to the heat-conducting structure.

[0022] In this embodiment, a first slot 4 is provided inside the protective shell 1, a first block 6 is fixed on the protective top plate 2, the first block 6 corresponds to the first slot 4, a second slot 5 is provided inside the wire feeding groove 3, and a second block 7 is fixed on the auxiliary top plate 8, the second block 7 corresponds to the second slot 5.

[0023] Specifically, the top of the three busbars is protected by the protective top plate 2, and a single busbar is protected by the auxiliary top plate 8. There is a gap between the auxiliary top plate 8 and the protective top plate 2, which can form a buffer space.

[0024] When maintenance is required on a particular busbar, the protective top plate 2 can be removed, and then the auxiliary top plate 8 above that busbar can be removed separately, thus avoiding any impact on the other two busbars and providing good protection for the busbar.

[0025] The heat-conducting structure includes multiple second elastic telescopic rods 14 fixed in the wire-laying groove 3. The bottom of the second elastic telescopic rods 14 and the protective shell 1 are both made of heat-conducting material. The ends of the second elastic telescopic rods 14 are fixed with heat-conducting plates 15. The heat dissipation structure includes an air duct 11 opened in the protective shell 1. Multiple heat dissipation plates 12 are fixed in the air duct 11.

[0026] Specifically, the air outlet of the external fan can be inserted into the air duct 11 to blow air into the air duct 11, thereby dissipating heat from the heat sink 12. Alternatively, the bottom of the air duct 11 can be removed to expose the heat sink 12 to the outside, allowing the heat sink 12 to exchange heat with the outside.

[0027] By pushing the heat-conducting plate 15 into contact with the busbar through the second elastic telescopic rod 14, heat can be conducted, thereby transferring heat to the heat dissipation plate 12, and thus dissipating heat through the heat dissipation plate 12.

[0028] The first elastic telescopic rod 13 includes a first rod body 16 and a second rod body 17. The first rod body 16 and the second rod body 17 are slidably connected. A first spring 18 is fixed between the first rod body 16 and the second rod body 17. A pressure plate 20 is fixed on the first rod body 16. A protective pad 19 is fixed on the pressure plate 20. A sliding groove 25 is opened in the first rod body 16. A pressure rod 21 is installed in the sliding groove 25. The fixing structure includes a fixing block 22 that is slidably fitted in the first rod body 16. A second spring 23 is installed between the fixing block 22 and the first rod body 16. A third spring 24 is fixed between the pressure rod 21 and the sliding groove 25. The pressure rod 21 corresponds to the fixing block 22.

[0029] Specifically, the busbar is placed between multiple pressure plates 20. At this time, the first spring 18 pushes the first rod 16 so that the protective pad 19 comes into contact with the busbar. Then the busbar squeezes the pressure rod 21, causing the pressure rod 21 to slide in the slide groove 25, thereby squeezing the fixing block 22 to both sides, so that the fixing block 22 comes into contact with the inner wall of the second rod 17, thereby increasing friction and thus fixing the length of the first elastic telescopic rod 13.

[0030] Specifically, when the busbar needs protection, the busbar is placed into the cable tray 3. The pressure plate 20 is pushed by the first elastic telescopic rod 13, causing the pressure plate 20 to squeeze the busbar, thus squeezing and fixing the busbar. Then, the length of the first elastic telescopic rod 13 is fixed by the pressure rod 21 and the fixing block 22, thereby fixing the position of the busbar. Then, the auxiliary top plate 8 and the protective top plate 2 are installed to protect the busbar. The inner protective plate 9 has a honeycomb structure, which can achieve a good protective effect.

[0031] During use, heat can be transferred to the heat sink 12 through the heat conduction plate 15 and the second elastic telescopic rod 14, and then heat exchange can be carried out with the outside air through the heat sink 12, thereby achieving a good heat dissipation effect and preventing the busbar from directly contacting the outside air, which could lead to moisture and other issues.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
