Description

Technical Field

[0001] This utility model relates to busbar application technology, specifically to a busbar device that is easy to replace. Background Technology

[0002] With the rapid development of electrical automation, various industries are using electrical facilities more extensively, placing high demands on their stable and reliable operation. Busbars, due to their structural characteristics, can connect multiple circuit lines, and their heat dissipation capacity is significantly improved compared to conventional cable connections. However, in current situations, because busbars need to connect multiple lines, multiple busbars are often integrated side-by-side in electrical installations to reduce space usage. This leads to a decrease in the busbar's heat dissipation performance. Crucially, when a busbar fails and needs replacement, the integration of multiple busbars makes replacement cumbersome, requiring complete disassembly. This complex and time-consuming process significantly impacts the efficiency of electrical installations. Utility Model Content

The fixing plate and the fixing slot are used to fix the heat dissipation base plate and the heat dissipation top cover, thus completing the fixed connection.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1 to 3 As shown, a replaceable bus device includes a bus assembly 1 and an access device 2. The bus assembly 1 comprises a first bus 101, a second bus 102, and a third bus 103, arranged vertically from top to bottom. The first bus 101, second bus 102, and third bus 103 are all fixedly connected to the access device 2. The access device 2 includes a main bus switch 201, a first bus switch 202, a second bus switch 203, and a third bus switch 204, arranged horizontally. The main bus switch 201 is located at the beginning of the access device 2.

[0029] The first busbar 101, the second busbar 102, and the third busbar 103 are all provided with a heat dissipation housing 104 and a connecting copper busbar 105. The heat dissipation housing 104 includes a heat dissipation top cover 1042 and a heat dissipation bottom plate 1041. Both the heat dissipation top cover 1042 and the heat dissipation bottom plate 1041 are provided with heat dissipation grilles to provide heat dissipation for the connecting copper busbar 105.

[0030] like Figures 2 to 4 As shown, the heat dissipation base plate 1041 is also provided with a supporting reinforcing strip 1043, which is cross-shaped and intersects horizontally and vertically at the middle of the heat dissipation base plate 1041. The connecting copper busbar 105 abuts against the supporting reinforcing strip 1043. The heat dissipation base plate 1041 is provided with a fixing plate 1044, and the heat dissipation top cover 1042 is provided with a fixing slot 1045. The fixing plate 1044 and the fixing slot 1045 are used to fix the heat dissipation base plate 1041 and the heat dissipation top cover 1042, thus completing the fixed connection. The side of the heat dissipation top cover 1041 is also provided with an auxiliary opening 1046 to facilitate opening the heat dissipation top cover 1042 with tools. The auxiliary opening 1046 is mainly provided to facilitate the inspection of the actual usage of the internal copper busbar during the replacement of a single busbar. The main bus switch 201 is equipped with a function display screen 2011, which has a built-in temperature sensor for monitoring the operating temperature of the entire bus assembly 1. Based on the information displayed, the screen shows whether the operating status of each bus is good, improving the efficiency of maintenance identification and verification.

[0031] like Figure 2 As shown, the access terminals on the main bus switch 201 are connected from left to right to the first busbar 101, the second busbar 102, and the third busbar 103, respectively, via connecting copper busbars 105. The first busbar 101 is located above the second busbar 102, and the second busbar 102 is located above the third busbar 103. All connecting copper busbars 105 connected to the main bus switch 201 are at the same horizontal level.

[0032] like Figures 2-3As shown, the main busbar 201 and the connecting copper busbars 105 are all at the same horizontal level. Spacing is created between the first busbar 101, the second return busbar 102, and the third busbar 103, improving heat dissipation and further extending the overall service life of the busbar device. By arranging multiple busbars in layers, they do not interfere with each other. Replacing a single busbar is simple and convenient, avoiding the cumbersome process of dismantling all busbars to replace a single one, thus improving the ease of device maintenance. Furthermore, to adapt to actual production applications, the busbar device can be combined and added or subtracted to meet specific connection needs. The above embodiment is merely one example and is not limited to the actual practical application of this embodiment or other combinations and connection methods, all of which fall within the scope of protection of this utility model.
