Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar housing with arc protection. Background Technology

[0002] Busbar trunking is a high-current-intensive electrical device used for power distribution and transmission. It is a replacement or upgrade solution for traditional cables in high-current applications and is widely used in industrial plants, commercial buildings, data centers, high-rise buildings, rail transit, power plants and other places that require large-capacity, centralized and safe power supply.

[0003] There are many types of existing busbar trunking. One type of busbar trunking can be plugged into an external electrical box. However, when the busbar trunking and the external electrical box are disconnected while energized, an electric arc will be generated between their conductive plates. An electric arc is a high-temperature phenomenon, which will cause burn damage to the conductive plates of the busbar trunking. At the same time, the electric arc will also damage the insulation layer on the outer surface of the busbar trunking. Therefore, the existing busbar trunking that can be plugged into the electrical box is inconvenient to use. To address this, we provide a busbar trunking shell with arc protection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing busbar trunking interfaces that lack arc-resistant functionality, and to provide an arc-resistant busbar trunking housing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a busbar trunking shell with anti-arc protection, comprising: a busbar trunking body, a protective mechanism on the top of the busbar trunking body, the protective mechanism including a mounting groove, the mounting groove being formed on the outer surface of the busbar trunking body, a connecting frame inside the mounting groove, the connecting frame being slidably connected to the inner wall of the busbar trunking body, an anti-arc plate inside the connecting frame, the anti-arc plate being fixedly connected to the connecting frame, a guide rod inside the busbar trunking body, a limiting piece sleeved on the outer surface of the guide rod, the limiting piece being slidably connected to the guide rod, the limiting piece being fixedly connected to the connecting frame, a spring sleeved on the outer surface of the guide rod, a cover plate on the top of the busbar trunking body, an auxiliary mechanism at one end of the cover plate, the auxiliary mechanism including a connecting block.

[0006] In a preferred embodiment, the guide rod is fixedly connected to the inner wall of the busbar trunking body, and the two ends of the spring are respectively fixedly connected to the outer surface of the limiting plate and the inner wall of the busbar trunking body.

[0011] In a preferred embodiment, a magnet is fitted inside the connecting block two, and the magnet is fixedly connected to the connecting block two.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, by setting up a protective mechanism, with the arc-resistant protection structure of the protective mechanism placed inside the outer shell of the busbar trunking interface, provides arc-resistant protection at the busbar trunking interface.

At the same time, an auxiliary mechanism is set up, which can be used in conjunction with the cover plate to ensure that the cover plate remains stable after it is attached to the busbar trunking body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: an arc-resistant busbar trunking shell, comprising: a busbar trunking body 1, a protective mechanism 2 on the top of the busbar trunking body 1, the protective mechanism 2 including a mounting groove 21, the mounting groove 21 being formed on the outer surface of the busbar trunking body 1, a connecting frame 22 inside the mounting groove 21, the connecting frame 22 being slidably connected to the inner wall of the busbar trunking body 1, an arc-resistant plate 23 inside the connecting frame 22, the arc-resistant plate 23 being fixedly connected to the connecting frame 22, a guide rod 24 inside the busbar trunking body 1, a limiting plate 25 sleeved on the outer surface of the guide rod 24, the limiting plate 25 being slidably connected to the guide rod 24, and the limiting plate 25 being connected to the connecting frame 22. The guide rod 24 is fixedly connected to the outer surface of the guide rod 24 and a spring 26 is sleeved on it. The top of the busbar trunking body 1 is provided with a cover plate 27. One end of the cover plate 27 is provided with an auxiliary mechanism 3. The auxiliary mechanism 3 includes a connecting block 31. The guide rod 24 is fixedly connected to the inner wall of the busbar trunking body 1. The two ends of the spring 26 are fixedly connected to the outer surface of the limiting plate 25 and the inner wall of the busbar trunking body 1, respectively. A fixing block 28 is fixedly connected to the outer surface of the busbar trunking body 1. A rotating shaft 29 is provided inside the fixing block 28. The rotating shaft 29 is fixedly connected to the fixing block 28. A rotating block 201 is sleeved on the outer surface of the rotating shaft 29. The rotating block 201 is rotatably connected to the rotating shaft 29. The rotating block 201 is fixedly connected to the cover plate 27.

[0025] In this embodiment, by opening an installation slot 21 on the busbar trunking body 1, the connecting frame 22 and the anti-arc plate 23 can be placed. Therefore, when the busbar trunking body 1 is connected to the external electrical box, the connecting frame 22 and the anti-arc plate 23 will not affect the electrical box. Multiple anti-arc plates 23 are provided and arranged at intervals. These anti-arc plates 23 are existing items made of special materials. Thus, the anti-arc plates 23 can attract the electric arc generated when the busbar trunking body 1 is energized and separated from the electrical box, so that the electric arc is absorbed when it is transmitted through multiple anti-arc plates 23. The circuit is divided into multiple short arcs to transfer the heat generated by the electric arc and reduce the damage to the busbar trunking body 1 caused by the electric arc. In addition, a spring 26 is provided, and the spring 26 is compressed by the limiting plate 25 to generate elastic force. The elastic force of the spring 26 can work with the limiting plate 25 to drive the connecting frame 22 and the anti-arc plate 23 to reset in time, so that the connecting frame 22 can maintain continuous contact with the box body of the electrical box. Thus, the anti-arc plate 23 can move with the separation of the electrical box to ensure that the anti-arc plate 23 can separate the electric arc generated between the electrical box and the busbar trunking body 1.

[0026] Example 2

[0027] like Figures 1-5 As shown, connecting block 1 31 is fixedly connected to busbar trunking body 1. Connecting block 2 32 is provided on the top of connecting block 1 31. Connecting block 2 32 is fixedly connected to cover plate 27. Magnet 1 33 is sleeved inside connecting block 1 31. Magnet 1 33 is fixedly connected to connecting block 1 31. Magnet 2 34 is sleeved inside connecting block 2 32. Magnet 2 34 is fixedly connected to connecting block 2 32.

[0028] In this embodiment, a cover plate 27 is provided, which can shield the insertion port and conductive block at the top of the busbar trunking body 1 to prevent foreign objects or dust from entering the insertion port of the busbar trunking body 1. At the same time, an auxiliary mechanism 3 is provided, which can work with the cover plate 27 to ensure that the cover plate 27 remains stable after it is attached to the busbar trunking body 1. Magnets 33 and 34 are provided, which can attract each other and fit tightly together to ensure the stable use of the cover plate 27.

[0029] Working principle:

[0030] like Figures 1-5As shown, in use, the busbar trunking body 1 can be plugged into the external electrical box. At this time, the limiting plate 25, guided by the guide rod 24, compresses the spring 26, causing the spring 26 to generate elastic force. When the external electrical box and the busbar trunking body 1 are energized and separated, an electric arc will be generated between their conductive plates. Simultaneously, as the electrical box moves, the elastic force of the spring 26 will be released instantaneously, resetting the limiting plate 25. The limiting plate 25 then drives the connecting frame 22 and the anti-arc plate 23 to reset, allowing the anti-arc plate 23 to contact the electric arc in time and divide the arc into multiple short arcs. The heat from the electric arc is transferred outwards, ensuring that the high temperature generated by the electric arc does not affect the conductive sheets and insulation layer of the busbar trunking body 1. When the electrical box is completely separated from the busbar trunking body 1, the electric arc will also disappear. Then, the cover plate 27 is flipped over. When the cover plate 27 is flipped over, it can drive the rotating block 201 to rotate around the rotating shaft 29 until the cover plate 27 is in contact with the outer shell of the busbar trunking body 1. At this time, the magnet 34 fixedly connected in the connecting block 22 can attract each other and be tightly connected with the magnet 33 in the connecting block 1. Thus, the cover plate 27 is in a relatively stable state, so that the cover plate 27 can protect the outer shell of the busbar trunking body 1.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
