Description

Bus duct

Technical Field

Embodiments of the present disclosure relate generally to electrical devices, and more particularly, to a bus duct.

Background

A busway is a closed metal device used to distribute large amounts of power to various components of a decentralized system. Wire and cable have been increasingly replaced in indoor low voltage power transmission mains engineering projects. For example, a bus duct may be provided between the switchgear and the transformer.

In the traditional scheme, a plurality of phase lines of a bus in a bus duct are all enclosed in an accommodating cavity of the bus duct, and the structure is not beneficial to heat dissipation of the phase lines. In addition, the manufacturing process of the bus duct in the traditional scheme is complex, and assembly and cost saving are not facilitated.

SUMMERY OF THE UTILITY MODEL

To at least partially solve the problems of the prior art and other potential problems, a bus duct with simple structure and easy heat dissipation is provided.

In a first aspect of the present disclosure, a bus duct is provided. The bus duct comprises a first side plate, a second side plate and a middle plate which are parallel to each other. The intermediate plate is integrally formed between the first side plate and the second side plate to partition a space between the first side plate and the second side plate into a first accommodating portion and a second accommodating portion for respectively accommodating a plurality of phase lines of the bus bar in the bus duct.

The first and second side plates and the intermediate plate of the bus duct proposed in the first aspect are integrally configured, so that a manufacturing process of the bus duct is simplified. In addition, the space between the side plates is divided into different accommodating areas for accommodating the phase lines by the middle plate, so that the problem of heat dissipation caused by the fact that the phase lines are densely arranged in the same area is solved.

In some embodiments, the busway further comprises a first cover plate and a second cover plate. First and second cover plates are coupled between the first and second side plates and are respectively arranged parallel to the middle plate on opposite sides of the middle plate.

In some embodiments, the first cover panel includes a first engagement portion adapted to be connected to the first side panel and a second engagement portion adapted to be connected to the second side panel. The second cover panel includes a third engagement portion adapted to be connected to the first side panel and a fourth engagement portion adapted to be connected to the second side panel.

The first cover plate and the second cover plate are used for closing phase lines in the bus duct. The cover plate in the embodiments of the present disclosure can be directly connected with the side plate to further reduce the complexity of manufacturing, compared to the cover plate in the conventional scheme.

In some embodiments, the first and third joints are adapted to be riveted to the first side plate and the second and fourth joints are adapted to be riveted to the second side plate, respectively.

In some embodiments, the first and third joints are adapted to be welded to the first side plate and the second and fourth joints are adapted to be welded to the second side plate, respectively.

The first and second cover panels may be attached to the side panels in a variety of ways, in this way increasing the flexibility of installation.

In some embodiments, the first side panel, the second side panel, and the intermediate panel are integrally constructed by an aluminum extrusion process.

In some embodiments, the first and second cover plates are configured as aluminum extrusions or aluminum benders.

In this way, the complexity of the side plates, the middle plates and the cover plate of the bus duct can be effectively reduced, the production efficiency is improved, and the production cost is saved. Furthermore, the side plates, the intermediate plate and the cover plate made of aluminum are particularly advantageous for the heat dissipation of the phase lines in the bus duct because of the good thermal conductivity.

In some embodiments, the first side plate, the second side plate and the middle plate are provided as a ground wire of the bus duct.

In some embodiments, the intermediate plate includes an extension exposed from a space between the first side plate and the second side plate in an extending direction of the bus duct.

In some embodiments, the first side plate, the second side plate, the first cover plate and the second cover plate are provided as a ground wire of the bus duct.

Therefore, the ground wire in the bus duct can be realized in two modes, and the use flexibility of the product is improved.

The summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. The summary is not intended to identify key features or essential features of the disclosure, nor is it intended to limit the scope of the disclosure.

As described above, in the conventional bus duct, the plurality of phase lines of the bus bar are enclosed in the accommodating cavity of the bus duct, which is disadvantageous for heat dissipation of the phase lines. In addition, the manufacturing process of the bus duct in the traditional scheme is complex, and assembly and cost saving are not facilitated.

To address the above and other potential problems, embodiments of the present disclosure provide a bus duct that is simple to manufacture and easy to dissipate heat. As shown in fig. 1, the bus duct 100 includes a first side plate 101 and a second side plate 102. The first side plate 101 and the second side plate 102 are arranged parallel to each other. Busway 100 also includes intermediate plate 103. The intermediate plate 103 is integrally formed between the first side plate 101 and the second side plate 102. The intermediate plate 103 partitions a space between the first side plate 101 and the second side plate 102 into a first accommodation portion 121 and a second accommodation portion 122. The first receiving portion 121 and the second receiving portion 122 may be respectively used for receiving a plurality of phase lines of a bus bar in the bus duct.

In some embodiments, the first and

second side plates

101 and 102 and the middle plate 103 of the busway 100 are integrally configured such that a manufacturing process of the busway 100 is simplified. In addition, since the middle plate 103 divides the space between the first side plate 101 and the second side plate 102 into the first receiving portion 121 and the second receiving portion 122 for receiving different phase lines, a heat dissipation problem due to the phase lines being densely located in the same area is avoided.

In some embodiments, busway 100 further comprises a plurality of cover plates disposed between first side plate 101 and second side plate 102. Fig. 2 shows a schematic of a busway 100 according to an embodiment of the present disclosure including a cover plate. As shown in fig. 2, bus duct 100 includes a first cover plate 111 and a second cover plate 112 in addition to the components already shown in fig. 1. A first cover 111 and a second cover 112 are coupled between the first side plate 101 and the second side plate 102 and are arranged parallel to the intermediate plate 103 on opposite sides of the intermediate plate 103, respectively.

As can be seen in fig. 2, the first cover 111 and the second cover 112 may enclose a first accommodation 121 and a second accommodation 122, respectively, between the first side plate 101 and the second side plate 102, separated by the middle plate 103. As described above, the first receiving portion 121 and the second receiving portion 122 may be respectively used for receiving a plurality of phase lines of a bus bar in the bus duct. Fig. 3 shows a schematic of a bus duct according to an embodiment of the present disclosure fitted with a bus bar.

As shown in fig. 3,

phase lines

131 and 132 are accommodated in the first accommodation portion 121 and

phase lines

133 and 134 are accommodated in the second accommodation portion 122. Although two phase lines each accommodated in the first and

second accommodation parts

121 and 122 are shown in the example of fig. 3. It should be understood that the number of phase lines housed in the bus duct may be increased or decreased depending on the requirements of other electrical devices connected to the bus duct.

Referring back to fig. 2, the first cover plate 111 includes a first engagement portion 113 adapted to be connected to the first side plate 101 and a second engagement portion 114 adapted to be connected to the second side plate 102. The second cover plate 112 comprises a third joint 115 adapted to be connected to the first side plate 101 and a fourth joint 116 adapted to be connected to the second side plate 102.

The connection between the engaging portion of the cover plate and the side plate may be achieved in various ways. In some embodiments, the first joint 113 of the first cover plate 111 and the third joint of the second cover plate 112 are adapted to be riveted to the first side plate 101, respectively. The second joint 114 of the first cover plate 111 and the fourth joint 116 of the second cover plate 112 are adapted to be riveted to the second side plate 102, respectively.

In some embodiments, the first joint 113 of the first cover plate 111 and the third joint of the second cover plate 112 are adapted to be welded to the first side plate 101, respectively. The second joint portion 114 of the first cover plate 111 and the fourth joint portion 116 of the second cover plate 112 are adapted to be welded to the second side plate 102, respectively.

The variety of the manufacturing process of the bus duct is improved through various connecting modes. Whether by riveting or welding, it can be seen from fig. 2 that the various joints of the cover plate and the side plates are directly connected, which also simplifies to some extent the manufacture of the bus duct.

In some embodiments, the first side panel 101, the second side panel 102, and the middle panel 103 are integrally constructed by an aluminum extrusion process. The first cover plate 111 and the second cover plate 112 are configured as aluminum extrusions or aluminum bendings.

In this way, the complexity of the side plates, the middle plates and the cover plate of the bus duct can be effectively reduced, the production efficiency is improved, and the production cost is saved. Furthermore, the side plates, the intermediate plate and the cover plate made of aluminum are particularly advantageous for the heat dissipation of the phase lines in the bus duct because of the good thermal conductivity. The heat concentrated in the phase line can be rapidly conducted to the side plates through the middle plate and then released into the air, so that the overheating problem in the conventional solution is significantly improved.

The bus duct 100 according to the embodiment of the present disclosure can implement different forms of ground wire arrangements to meet the needs of different structures. Fig. 4 and 5 illustrate side and perspective views, respectively, of a bus duct according to an embodiment of the present disclosure with an exemplary ground wire arrangement. As shown in fig. 4 and 5, the first side plate 101, the second side plate 102, and the intermediate plate 103 are provided as ground lines of the bus duct.

With the intermediate plate 103 as the ground, the intermediate plate 103 includes an extension 119 exposed from a space between the first side plate 101 and the second side plate 102 in the extending direction X of the bus duct 100. As can be seen in fig. 4 and 5, extension 119 is between phase lines 131,132 and

phase lines

133, 134.

Fig. 6 and 7 show side and perspective views, respectively, of a bus duct according to an embodiment of the present disclosure with another exemplary ground wire arrangement. As shown in fig. 6 and 7, the first side plate 101, the second side plate 102, the first cover plate 111, and the second cover plate 112 are provided as ground lines of the bus duct 100.

The first cover 111 and the second cover 112 in fig. 6 and 7 each have a first extension 117 and a second extension 118 extending from between the first side plate 101 and the second side plate 102. It can be seen that in the example shown in fig. 6 and 7, the ground line is located outside the

phase lines

131 and 134.

From this, can realize the ground wire in the bus duct with different modes, improve the use flexibility ratio of product.
