Description

Technical Field

[0001] This utility model relates to the field of electric arc technology in power distribution cabinets, and more specifically to an electric arc isolation baffle structure for power distribution cabinets. Background Technology

[0002] Electrical arcing in a distribution cabinet refers to a high-temperature plasma discharge phenomenon caused by air breakdown due to insulation failure, poor contact, or short circuits. Its characteristics include instantaneous temperatures reaching thousands of degrees Celsius, accompanied by intense light, explosive pressure waves, and toxic gases (such as ozone), making it highly susceptible to fire and equipment damage. It is commonly found at circuit breaker tripping points and busbar connection points, and requires prevention through arc-extinguishing devices (such as magnetic blowout arc extinguishing and insulating barrier isolation), real-time temperature monitoring, and a five-proof interlocking design. Regular maintenance is also required to eliminate potential hazards such as oxidation and dust accumulation.

[0003] According to the publication (announcement) number: CN203387087U, publication (announcement) date: 2014-01-08, a high-voltage distribution cabinet with a ventilation device is disclosed, including a distribution cabinet assembly frame and a distribution cabinet shell. The distribution cabinet shell is disposed outside the distribution cabinet assembly frame. The distribution cabinet assembly frame is provided with a component mounting rack. A control box is installed in the middle of the distribution cabinet assembly frame. A fan is disposed inside the distribution cabinet assembly frame. A controller for controlling the operation of the fan is disposed inside the control box. The output terminal of the controller is connected to the input terminal of the fan. A first ventilation window is disposed on the upper side of the distribution cabinet shell. A second ventilation window is disposed directly below the distribution cabinet shell. Both the first ventilation window and the second ventilation window are provided with filters and grilles.

[0004] As can be seen from the aforementioned patents and prior art, if an electric arc flash occurs inside the distribution cabinet, it can lead to a fire inside the cabinet. Furthermore, when an electric arc fault occurs inside the cabinet, the high-temperature airflow and metal splashes can easily spread to adjacent compartments, expanding the scope of the accident. Utility Model Content

[0005] The purpose of this utility model is to provide an arc-breaking baffle structure for a power distribution cabinet, which ensures that an arc fault will not affect adjacent compartments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an arc-breaking baffle structure for a power distribution cabinet, comprising a cabinet body, a placement groove on the cabinet body, a first sliding groove in the placement groove, a horizontal plate slidably disposed in the first sliding groove, sliders symmetrically disposed on both sides of the horizontal plate, the sliders sliding in the first sliding groove, V-shaped plates symmetrically disposed on both sides of the horizontal plate, a plurality of first slits arranged in a linear array on the horizontal plate, and a plurality of second slits arranged in a linear array on the V-shaped plates.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-4 As shown, an arc-breaking baffle structure for a power distribution cabinet includes a cabinet body 1. A placement groove 10 is provided on the cabinet body 10. A first sliding groove 12 is provided in the placement groove 10. A horizontal plate 21 is slidably arranged in the first sliding groove 12. Sliding blocks 20 are symmetrically arranged on both sides of the horizontal plate 21. The sliding blocks 20 slide in the first sliding groove 12. V-shaped plates 22 are symmetrically arranged on both sides of the horizontal plate 21. A plurality of first gaps 23 arranged in a linear array are provided on the horizontal plate 21. A plurality of second gaps 24 arranged in a linear array are provided on the V-shaped plates 22.

[0018] Specifically, in use, a horizontal plate 21 is installed inside the cabinet 1. Pushing the horizontal plate 21 moves it until the sliders 20 at both ends are engaged in the first sliding groove 12, thus locking the horizontal plate 21 inside the cabinet 1. In this embodiment, the horizontal plate 21 divides the cabinet 1 into multiple compartments. If an arc fault occurs inside the cabinet 1, the arc will first be isolated by the multiple V-shaped plates 22 on the horizontal plate 21. The V-shaped plates 22 are coated with a ceramic arc-extinguishing layer, and the second gap 24 on the V-shaped plates 22 will delay the transmission of arc energy. After being transmitted to the horizontal plate 21, the first gap 23 on the horizontal plate 21 will also delay the arc, preventing damage to adjacent compartments.

[0019] In the above scheme, multiple horizontal plates 21 are installed through the placement slot 10 on the cabinet 1. The first sliding groove 12 in the placement slot 10 is implemented. The horizontal plates 21 slide in the first sliding groove 12 through the sliders 20 on both sides. The V-shaped plate 22 on the horizontal plate 21 can block the arc when it occurs. The first gap 23 on the horizontal plate 21 and the second gap 24 of the V-shaped plate 22 can slow down the transmission of arc energy when an arc occurs.

[0020] As a further embodiment provided by this utility model, according to Figure 1 and Figure 2 As shown, placement blocks 13 are symmetrically arranged in the placement groove 10, and a predetermined gap is left between the two placement blocks 13 to form a second sliding groove 14.

[0021] Furthermore, a partition 15 is slidably disposed within the second chute 14.

[0022] Specifically, all components inside the distribution cabinet are installed on partition 15.

[0023] As a further embodiment provided by this utility model, according to Figure 2 As shown, a fixing hole 16 is provided on the placement block 13, and a fixing rod 18 is provided in the fixing hole 16.

[0024] Furthermore, the fixing rod 18 passes through the fixing hole 16 and the placement block 13 in sequence.

[0025] Furthermore, a nut 19 is provided on the fixing rod 18.

[0026] Specifically, after inserting the partition 15 into the second slide groove 14, the fixing rod 18 is inserted after the fixing rod 18 passes through the fixing hole 16. The thread at the end of the fixing rod 18 is threadedly engaged with the thread on the inner wall of the second slide groove 14 on the placement block 13, thereby fixing the partition 15 into the second slide groove 14.

[0027] Working principle: In use, open the door 11, install the horizontal plate 21 inside the cabinet 1, and slide the sliders 20 at both ends of the horizontal plate 21 into the first slide groove 12. The sliding horizontal plate 21 will be fixed inside the cabinet 1, dividing the cabinet 1 into multiple compartments. Then, insert the partition plate 15 into the second slide groove 14, insert the fixing rod 18 into the fixing hole 16 on the placement block 13, and then insert it into the second slide groove 14 and thread it onto the second slide groove 14. The partition 15 is fixed in the second slide 14. All components in the cabinet 1 are installed on the partition 15. If an electric arc fault occurs in the cabinet 1, the electric arc will first be isolated by multiple V-shaped plates 22 on the horizontal plate 21. The V-shaped plates 22 are coated with a ceramic arc-extinguishing layer. At the same time, the second gap 24 on the V-shaped plate 22 will delay the transmission of electric arc energy. After being transmitted to the horizontal plate 21, the first gap 23 on the horizontal plate 21 will also delay the electric arc, thus avoiding damage to adjacent compartments.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
