Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet for power supply safety. Background Art

[0002] Power engineering is the application of knowledge in physics, electronics and electrotechnical engineering to study the science and technology of power generation, transmission, conversion and utilization, as well as the design, manufacture, inspection and maintenance of power equipment. Power distribution cabinets for power supply safety are one of the power equipment and are important accessories in the power system.

[0003] Flameproof power supply safety distribution cabinets are commonly used in special places such as mines. Due to the limitations of the use environment, the distribution cabinets should avoid contact with the outside world during use. Therefore, flameproof power supply safety distribution cabinets have good sealing properties to ensure the safety of the distribution cabinets during use.

[0004] However, due to the good sealing performance of the explosion-proof power supply safety distribution cabinet, the heat dissipation effect inside the distribution cabinet is poor, which causes the internal electrical components to overheat when the distribution cabinet is in use; at the same time, the distribution cabinet will be in a vibrating environment in environments such as mines, causing the electrical components inside the distribution cabinet to loosen, posing a safety hazard.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0009] The power distribution cabinet body includes a first shell and a second shell. The second shell is arranged in the first shell. An interlayer is formed between the left and right side walls of the first shell and the second shell. The second shell is used for installing electrical components. The first shell is used to protect the second shell to ensure that the electrical components are isolated from the outside.

[0010] The temperature control component includes a phase change box, wherein a pair of phase change boxes are provided, and the pair of phase change boxes are respectively installed in the left and right interlayers of the first shell and the second shell, and the phase change box is fixedly connected to the side wall of the second shell, and an endothermic phase change material is provided in the phase change box, and a plurality of heat-conducting strips are installed on the bottom wall plate of the phase change box, and the lower end of the heat-conducting strip is buried in the ground; an endothermic phase change material is provided in the phase change box, and heat can be absorbed by the endothermic phase change material. Since the phase change box is fixedly connected to the side wall of the second shell, the heat generated by the electrical components in the second shell can be transferred to the phase change box and absorbed by the endothermic phase change material, thereby adjusting the temperature in the second shell. After the endothermic phase change material absorbs the heat, the absorbed heat needs to be released so that the temperature in the second shell can be continuously adjusted.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] like Figure 1 to Figure 6 As shown, a power distribution cabinet for power supply safety in one embodiment of the utility model includes a power distribution cabinet body 1, a temperature control component 2 and a buffer component 3.

[0033] like Figure 2 to Figure 4 As shown, the distribution cabinet body 1 includes a first shell 11 and a second shell 12.

Since the phase change box 21 is fixedly connected to the side wall of the second shell 12, the heat generated by the electrical components in the second shell 12 can be transferred to the phase change box 21 and absorbed by the endothermic phase change material 22, thereby realizing the adjustment of the temperature in the second shell 12. After the endothermic phase change material 22 absorbs the heat, it needs to release the absorbed heat so that the temperature inside the second shell 12 can be continuously adjusted. Therefore, a plurality of thermal conductive strips 24 are installed at the bottom of the phase change box 21. The heat absorbed by the endothermic phase change material 22 is transferred to the earth through the thermal conductive strips 24, thereby releasing the heat.

[0038] like Figure 4 As shown, the upper end of the heat-conducting strip 24 is placed in the phase change box 21, and the upper end of the heat-conducting strip 24 is fixedly connected to the heat-conducting plate 23, and the part of the heat-conducting plate 23 placed outside the phase change box 21 is provided with an elastic heat-conducting strip 25.

Since the second shell 12 and the first shell 11 will be displaced from each other under the influence of the outside world, an elastic heat-conducting strip 25 is provided on the heat-conducting plate 23 so that the elastic heat-conducting strip 25 can adapt to its displacement through deformation.

[0039] like Figure 3 and Figure 5 As shown, multiple heat-absorbing fins 26 are fixedly connected to the inner sides of the left and right side walls of the second housing 12, and the multiple heat-absorbing fins 26 are composed of multiple arcs. The heat emitted by the electrical components in the second housing 12 can be quickly absorbed and transferred by the multiple heat-absorbing fins 26, and finally the heat is absorbed by the heat-absorbing phase change material 22. The heat-absorbing fins 26 are arranged to be composed of multiple arcs, which increases the contact area between the heat-absorbing fins 26 and the air in the second housing 12, thereby improving the heat transfer effect.

[0040] like Figure 2 As shown, a feed port 27 is provided on the upper side of the front side wall of the phase change box 21, and a feed cover 28 is threadedly connected to the feed port 27.

[0043] like Figure 6 As shown, a pair of buffer springs 34 are installed in the slide groove 32, and the pair of buffer springs 34 are respectively arranged on the left and right sides of the slider 33. When the slider 33 moves laterally in the slide groove 32, the buffer spring 34 can be compressed, so that the movement of the slider 33 is buffered by the buffer spring 34, and then the movement of the second shell 12 is buffered, so that the electrical components in the second shell 12 are effectively buffered when vibrated, so as to prevent the electrical components from loosening and ensure the safety of the power distribution cabinet when in use.

[0044] like Figure 4 As shown, a plurality of elastic blocks 35 are provided at the bottom of the first housing 11, and the elastic blocks 35 are made of rubber material.
