Description

Technical Field

[0001] This utility model relates to the technical field of power distribution control, specifically a heat shield for a central cabinet heating system. Background Technology

[0002] A central switchgear is a common power distribution device used in the secondary substation systems of power plants for receiving and transmitting power. It contains various busbars, instruments, circuit breakers, and cables. To prevent internal electrical components from becoming damp and causing flashover accidents, heaters are typically installed inside the central switchgear for continuous dehumidification. Early heaters were usually located at the bottom of the cabinet and exposed. Later, because maintenance and repair work required access through the front or rear doors, workers could easily touch the heaters and suffer burns. Therefore, later versions installed aluminum covers to isolate the heaters and prevent direct contact. However, the heaters inside central switchgear typically have high power, with surface temperatures reaching over 180°C. Even with the covers, their proximity to the heaters still causes them to reach very high temperatures, making them difficult to touch. Furthermore, the covers restrict heat flow from the heaters themselves, thus affecting the dehumidification effect within the cabinet. Utility Model Content

[0003] The purpose of this utility model is to provide a centrally located cabinet heating anti-scalding cover to solve the problem mentioned in the background art that the existing added heater anti-scalding cover does not achieve a good anti-scalding effect and affects the dehumidification effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A central cabinet heating anti-scalding cover includes a heater mounting box disposed at the bottom of the central cabinet body. The heater mounting box includes an outer cover and an inner mounting box. The heater is installed in the inner mounting box and is fixedly connected to the bottom of the central cabinet body. The outer cover is slidably connected to the inner mounting box on the inner side through a sliding track structure. An elastic element is connected between the outer cover and the inner wall of the central cabinet body.

[0006] The outer top surface of the outer casing is provided with a wedge block, and the side of the wedge block facing the outside of the central cabinet is inclined. The central cabinet is also connected to a rotatable door panel, and a support rod is provided on the bottom inner side of the door panel. The support rod and the wedge block are on the same horizontal plane.

[0007] As a further embodiment of this utility model, the outer casing surface is also provided with multiple heat dissipation holes.

[0008] As a further embodiment of this utility model: the outer casing covers the top and both sides of the inner mounting box respectively.

[0009] As a further embodiment of this utility model, the length of the outer casing is greater than that of the inner mounting box.

[0010] As a further embodiment of this invention, the end of the strut is configured as a spherical surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a heat shield design that is linked to the opening and closing action of the central cabinet door. When the door is closed, the heater is exposed, and the outer cover does not approach the inner mounting box and the heater, so it is not easily affected by the heat flow and its own temperature rises. After the door is opened, the outer cover automatically covers the inner mounting box, thus preventing people from touching the heater. Moreover, since the time between the outer cover and the heater is short, even if people touch the outer cover, they will not be burned. This solves the problem of adding a heat shield affecting the heat flow and moisture-proof effect of the heater and effectively prevents burns. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a central cabinet heating anti-scalding cover includes a heater mounting box 2 disposed at the bottom of the central cabinet 1. The heater mounting box 2 includes an outer cover 21 and an inner mounting box 22. The heater is installed inside the inner mounting box 22. The inner mounting box 22 is fixedly connected to the bottom of the central cabinet 1. The outer cover 21 covers the top and both sides of the inner mounting box 22 respectively, and is slidably connected to it on the inner side through a slide structure 23.

[0018] The outer top surface of the outer casing 21 is provided with a wedge 212. The side of the wedge 212 facing the outside of the central cabinet 1 is inclined. The central cabinet 1 is also connected to a rotatable door panel 3. The bottom inner side of the door panel 3 is provided with a support rod 31. The support rod 31 and the wedge 212 are on the same horizontal plane. The end of the support rod 31 is set as a spherical surface.

[0019] An elastic element 11, which is a tension spring, is connected between the outer casing 21 and the inner wall of the central cabinet 1. When the door panel 3 is closed, the tension spring is in a stretched state, and the outer casing 21 is at the end of the inner mounting box 22, exposing the inner mounting box 22 and its heater inside the cabinet. The generated heat flow is used to prevent moisture inside the cabinet. When maintenance or other operations are performed, the door panel 3 needs to be opened. When the door panel 3 is opened, the tension spring contracts and pulls the outer casing 21 above the inner mounting box 22, covering the inner mounting box 22 inside. When maintenance or other operations are completed and the door panel 3 is closed, the support rod 31 begins to contact the inclined surface of the wedge block 212. The thrust generated by the support rod 31 on the inclined surface of the wedge block 212 pushes the outer casing 21 to move. After the door panel 3 is completely sealed, the outer casing 21 is pushed to one end of the inner mounting box 22, exposing the heater. In summary, when the door panel 3 is closed, the heater is exposed, and the outer cover 21 is not close to the inner mounting box 22 and the heater, so it is not easily affected by the heat flow and its own temperature rises. When the door panel 3 is opened, the outer cover 21 automatically covers the inner mounting box 22, thus preventing people from touching the heater. Moreover, since the time the outer cover 21 is close to the heater is short, even if people touch the outer cover 21, they will not be burned.

[0020] The outer casing 21 is also provided with multiple heat dissipation holes 211 for heat dissipation, so that the heater can maintain a certain heat dissipation effect after the outer casing 21 is covered. The length of the outer casing 21 can be designed to be slightly longer than the inner mounting box 22. After being covered, the two ends of the inner mounting box 22 will also be inside the outer casing 21, thereby further reducing the possibility of personnel touching the inner mounting box 22.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
