Description

Power transmission bus with spaced insulation structure

The present invention relates to a spacing insulation structure, in particular to a spacing insulation structure for a power transmission bus.

In recent years, due to the improvement of technology, many buildings and equipment installed in factories now require large power supply when operating. However, the quality, stability and safety of electricity are now very important. In the process of product production, if there is a problem with the transmission of power, resulting in the inability of the production line to operate normally, it will have a great impact on the manufacturer, especially for the high-tech industry. Traditional cables for power transmission can no longer ensure the safety of transmitting large amounts of power, because their small transmission area makes them prone to overheating, and they cannot immediately dissipate the heat, which can easily lead to power transmission accidents. In today's technology industry, most of them have switched to using power transmission buses as devices for transmitting large amounts of power to replace traditional cables with complicated installation methods. In addition, power transmission buses can be configured according to the layout of factories or buildings, which can save configuration space compared to cables.

Conventional power transmission buses use common insulating resins such as epoxy resins or polyurethane (PU) as insulating materials to mold and encapsulate the metal conductors used to transmit power. However, the flame retardancy of the materials used in the aforementioned conventional technologies is still insufficient. Once the temperature is too high, there is a risk of short circuits and fires.

In order to solve the above-mentioned known technical problems, one of the purposes of the embodiments of the present invention is to provide a spacer insulation structure for a power transmission bus, using improved materials to improve the electrical insulation (voltage resistance), weather resistance, water splashing (waterproof) and fire resistance during power transmission.

According to an embodiment of the present invention, a power transmission bus is provided, comprising a plurality of metal conductors and a plurality of insulating structures. The plurality of metal conductors are arranged at intervals, and each metal conductor comprises a body and two terminal ends. The body extends along a first direction, the two terminal ends are located at two ends of the metal conductor, and the direction of the connection of the two terminal ends is parallel to the first direction. The plurality of insulating structures are arranged at intervals with the plurality of metal conductors, wherein the length of each insulating structure defines the length of the body of the adjacent metal conductor.

In one embodiment, the insulating structure includes silicone resin, quartz sand, quartz powder and aluminum oxide powder.

Compared with the prior art, the insulation structure of the power transmission bus of the embodiment of the present invention has better electrical insulation, weather resistance, water splash resistance and fire resistance, and has the advantages of easy assembly and disassembly.

The following will use diagrams and text descriptions to disclose multiple implementations of the present invention. For the sake of clarity, many practical details are described in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In addition, in order to simplify the diagram, the structure and components of a rest will be drawn in a simple diagram in the diagram.

Please refer to Figure 1, which is a schematic three-dimensional diagram of the configuration of the metal conductor and the insulation structure of the power transmission bus according to an embodiment of the present invention. As shown in the figure, the embodiment of the present invention provides a power transmission bus 10, including a plurality of metal conductors 100 and a plurality of insulation structures 200. The plurality of metal conductors 100 are arranged at intervals, and each metal conductor 100 includes a body 110 and two terminal ends 120. The body 110 extends along a first direction D1, for example, along a direction in which the length of the power transmission bus 10 is longer. The two terminal ends 120 are located at the two ends of the metal conductor 100, that is, the direction of the connection of the two terminal ends 120 is parallel to the first direction D1.

A plurality of insulating structures 200 and a plurality of metal conductors 100 are disposed at intervals, wherein the length of each insulating structure 200 defines the length of the body 110 of the adjacent metal conductor 100. For example, the length of the insulating structure 200 in the first direction D1 may be shorter than the length of the metal conductor 100 in the first direction D1, so the length of the insulating structure 200 can define the length of the body 110 of the adjacent metal conductor 100. In other words, since the length of each body 110 is defined by the length of the adjacent insulating structure 200, the length of each body 110 is substantially the same as the length of the adjacent insulating structure 200 in the first direction D1. Specifically, the metal conductor 100 and the insulating structure 200 can be arranged as shown in FIG1 , in a staggered manner perpendicular to the first direction D1, that is, in the width direction D2, that is, the insulating structure 200, the metal conductor 100, the insulating structure 200, and the metal conductor 100 are repeatedly arranged.

The power transmission bus 10 is mainly composed of an insulating structure 200 wrapped around a metal conductor 100 to achieve a good insulation effect. Generally speaking, the metal conductor 100 can be made of copper or aluminum. The power transmission bus 10 can be used in, for example, distribution boards, distribution boxes, substations, and electric vehicle charging in power transmission and distribution systems to connect lines of the same voltage, but is not limited to this.

According to an embodiment of the present invention, the components of the insulating structure 200 may include an insulating sheet made of a formula of silicone resin, quartz sand, quartz powder, and aluminum oxide powder. Specifically, due to the components of the insulating structure 200, the insulating structure 200 has excellent properties such as high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, and high hardness. Therefore, when the metal conductor 100 in the power transmission bus 10 transmits a large current, the high temperature generated is less likely to damage the insulating structure 200, and the insulating structure 200 will not squeeze the adjacent metal conductor 100 and cause the entire power transmission bus 10 to deform or damage because the degree of thermal expansion is smaller. Furthermore, the high insulation of the insulating structure 200 can reduce the short circuit of adjacent metal conductors 100.

According to the embodiment of the present invention, the insulating structure 200 can be made into a sheet structure with a thickness of 1 to 12 mm, so as to be arranged alternately with the metal conductor 100, and adjacent insulating structures 200 are not easy to contact each other. When the insulating structure 200 is deformed due to long-term use or heat, it is less likely to affect the adjacent insulating structure 200.

According to an embodiment of the present invention, the insulating structure 200 can extend in a vertical first direction, such as in the height direction D3, and its length is greater than the length of the metal conductor 100 in the height direction D3, so as to further prevent the adjacent metal conductors 100 from contacting each other and causing adverse effects such as short circuits.

Please refer to FIG. 2, which is a front view of the insulating structure and buffering rubber of the power transmission bus according to the embodiment of the present invention. As shown in the figure, a buffering rubber 300 can be further arranged between the adjacent metal conductor 100 and the insulating structure 200, and the length of the buffering rubber 300 in the height direction D3 in FIG. 1 is less than the length of the metal conductor 100 in the height direction D3. The buffering rubber 300 can prevent the adjacent metal conductor 100 and the insulating structure 200 from being directly squeezed against each other due to thermal expansion caused by the thermal effect of the current when in use, causing adverse effects.

Please refer to Figures 3A and 3B. Figure 3A is a front view of the first fixing member of the power transmission bus according to an embodiment of the present invention, and Figure 3B is a schematic combination diagram of the power transmission bus and the first fixing member according to an embodiment of the present invention. As shown in the figure, the first fixing members 400 are arranged at intervals on the top of the insulating structure 200 and on the bottom of the insulating structure 200, and each first fixing member 400 partially shields the insulating structure 200. Each first fixing component 400 has a plurality of first grooves 410 on a side facing the insulating structure 200, and the first grooves 410 and the insulating structure 200 are fixed to each other one-to-one (as shown in FIG. 3A ). The three-dimensional assembly diagram of the first fixing component 400 and the insulating structure 200 can be shown in FIG. 3B . Therefore, the first fixing component 400 can reduce the damage to the power transmission bus 10 caused by a collision when the power transmission bus 10 is moved or transported.

In addition, the first groove 410 in the first fixing member 400 can also be arranged on the other side facing the insulating structure 200, and can serve as a drainage groove to prevent liquid from entering the insulating structure 200 and the metal conductor 100 below.

Please refer to Figures 4A to 4D, Figure 4A is a structural diagram of the second fixing component of the power transmission bus according to an embodiment of the present invention, Figure 4B is a schematic combination diagram of the second fixing component of the power transmission bus according to an embodiment of the present invention, Figure 4C is a schematic combination diagram of the folding cover of the power transmission bus according to an embodiment of the present invention, and Figure 4D is another schematic combination diagram of the folding cover of the power transmission bus according to an embodiment of the present invention. As shown in the figure, the power transmission bus 10 can set the second fixing component 500 at the top of the insulating structure 200 and between two adjacent first fixing components 400, as shown in Figure 4B.

Specifically, one end of each second fixing member 500 contacts one of the two adjacent first fixing members 400, and a gap d1 of a preset distance is provided between the other end of each second fixing member 500 and the other of the two first fixing members 400 (as shown in FIG. 4D ). Furthermore, each second fixing member 500 includes a first clamping structure 510 (as shown in FIG. 4A ), and the first clamping structure 510 is disposed on one side facing the insulating structure 200 to fix at least the insulating structure 200. The size of the first clamping structure 510 can be designed to be equal to the size of the corresponding insulating structure 200, so that when the second fixing member 500 is assembled to the insulating structure 200, there is no gap between the two and they are fully fixed.

In addition, a folding cover 520 can be provided to cover the first clamping structure 510 (as shown in FIG. 4C ), and one end of the folding cover 520 is located in the gap d1 (as shown in FIG. 4D ). For the convenience of manufacturing and assembly, the first fixing component 400 and the second fixing component 500 do not need to be directly manufactured to be consistent with the length of the insulating structure 200. Instead, a modular concept is used. For insulating structures 200 of different lengths, the insulating structure 200 and the metal conductor 100 are fixed and protected by segmented assembly, so that the area of the insulating structure 200 and the metal conductor 100 exposed in the air is reduced, reducing the chance of being affected by moisture.

Please refer to Figures 5A and 5B. Figure 5A is a structural diagram of a stabilizing component of a power transmission bus according to an embodiment of the present invention, and Figure 5B is a schematic assembly diagram of a stabilizing component of a power transmission bus according to an embodiment of the present invention. As shown in the figure, the power transmission bus 10 also has a stabilizing component 530, which is arranged at the top and bottom of the insulating structure 200 and at the junction with the metal conductor 100. Each stabilizing component 530 includes a first groove 410 and a second groove 531 (as shown in Figure 5A).

Specifically, the first groove 410 is located on one side facing the insulating structure 200, and fixes the insulating structure 200 in a one-to-one manner. The second groove 531 is located on one side facing the metal conductor 100, and fixes the metal conductor 100 in a one-to-one manner. The way in which the stabilizing component 530 is installed on the insulating structure 200 is shown in FIG5B. Moreover, the length of the insulating structure 200 in the height direction D3 as shown in FIG1 is longer than the length of the metal conductor 100 in the height direction D3 as shown in FIG1, so the height of the first groove 410 is higher than the second groove 531, so that when the stabilizing component 530 is installed on the insulating structure 200, the second groove 531 and the metal conductor 100 can be fully fitted without leaving a gap.

Since the first fixing member 400 and the second fixing member 500 on the insulating structure 200 are not fixed to the insulating structure 200 using components such as screws, there is still a possibility of sliding, so a stabilizing member 530 is set at the top and bottom of the insulating structure 200 near the connection end 120 of the metal conductor 100 to further fix the first fixing member 400 and the second fixing member 500 on the insulating structure 200.

Please refer to Figures 6A and 6B, Figure 6A is a schematic three-dimensional diagram of the outer shell of the power transmission bus according to an embodiment of the present invention, and Figure 6B is a front view of the outer shell of the power transmission bus according to an embodiment of the present invention. As shown in the figure, the power transmission bus 10 also has an outer shell 600, which is arranged on both sides of the power transmission bus 10, that is, the power transmission bus 10 is fixed from the top and bottom of the insulating structure 200 relative to the first fixing member 400 and the second fixing member 500, and the power transmission bus 10 can also be fixed from the left and right by the outer shell 600, and the outer shell 600 extends along the length direction of the power transmission bus 10 (i.e., the first direction D1). Furthermore, the metal conductor 100 and the insulating structure 200 in the power transmission bus 10 are covered by the first fixing member 400, the second fixing member 500, the outer shell 600, and the stabilizing member 530 to improve the insulation, waterproofness, fire resistance, and weather resistance of the power transmission bus 10.

The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention.
