Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to a switch cabinet. Background Art

[0002] Switchgear is an electrical device whose main function is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. The external line of the switchgear first enters the main control switch inside the cabinet, and then enters the branch control switch. Each branch is set according to its needs.

[0003] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and energy conversion in the power system; the components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protective devices.

[0004] In addition, most of the current switch cabinets are composed of multiple sealed boxes fixed together. When in use, each individual box in the switch cabinet will generate a high amount of heat. However, the heat dissipation effect of today's switch cabinets is poor, and the heat generated by the electrical components inside each individual box when working cannot be dissipated in time, which seriously affects the normal operation of the electrical components inside the switch cabinet, thereby shortening the service life of the electrical components inside the high and low voltage switch cabinets.

[0005] Some cabinets now have exhaust fans installed, which can generate some air flow inside the cabinet and achieve a certain heat dissipation effect. However, due to the poor sealing of the cabinet itself, the air flow generated inside the cabinet is not large, and for some electrical components with large heat dissipation, the air flow cannot flow through their location alone.

[0006] Therefore, how to improve the heat dissipation performance and dust removal performance of the switch cabinet and ensure the normal operation of the switch cabinet is the direction that technical personnel in this field have been working hard on. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0060] Example 1

[0061] like Figures 1 to 24 As shown, the present invention discloses a switch cabinet, comprising:

[0062] The cabinet body 1 has a partition plate 19 disposed inside the cabinet body 1 , an electrical component installation area 9 is formed above the partition plate 19 , and a filter chamber 10 is formed below the partition plate 19 .

[0063] The upper sealing door 2 is used to close the electrical component installation area 9, and the upper sealing door 2 can be rotated to open.

[0064] The lower sealing door 3 is used to close the filter chamber 10, and the lower sealing door 3 can be rotated to open.

[0065] The heat dissipation device is arranged inside the electrical component installation area 9, and includes a sliding heat storage device 13 and a track device. The sliding heat storage device 13 can slide or be fixed on the track device.

[0066] The filter device 14 is detachably fixed in the filter chamber 10 .

[0067] The air cooling device includes an air supply device 7, which is used to supply air to the filter chamber 10. After filtering by the filter device 14, the filtered cooling air flows to the electrical component installation area 9 and can cool the sliding heat storage device 13 by air.

[0068] Among them, the sliding heat storage device 13 can absorb the heat emitted by the electrical components in the electrical component installation area 9. When the heat storage and heat exchange plate 1303 on the sliding heat storage device 13 reaches a preset heat exchange temperature or a preset deformation amount, the sliding heat storage device 13 can slide on the track device under the action of the control device, and slide to the area where the cooling air is directly blown, and then the cooling air input by the air supply device 7 is filtered by the filter device 14 and directly blown to the sliding heat storage device 13. The cooled sliding heat storage device 13 slides again to the area with higher temperature in the electrical component installation area 9.

[0069] Since there are many electrical components inside the switch cabinet 100 and the use environment is relatively bad, in order to dissipate heat, the existing switch cabinet generally leaves a gap at the cabinet door joint when assembling the cabinet, or sets a heat dissipation hole on the shell component of the switch cabinet for air intake and heat dissipation. However, due to the relatively bad use environment of the switch cabinet, dust can easily enter the cabinet of the switch cabinet and accumulate on the electrical components in the cabinet. Since the electrical components in the cabinet are arranged closely, when the dust accumulates to a certain amount, it will generate a certain amount of static electricity, or seriously affect the heat dissipation effect of the electrical components themselves.

[0070] As an example of the present invention, a partition 19 is arranged inside the cabinet 1, and an electrical component installation area 9 is formed above the partition 19 for assembling and placing electrical components. An upper sealing door 2 is arranged on the front surface of the electrical component installation area 9 for rotatably sealing the electrical component installation area 9. A filter chamber 10 is formed below the partition 19. The cooling air entering the cabinet 1 is filtered by a filter device 14 arranged in the filter chamber 10. A lower sealing door 3 is arranged on the front surface of the filter chamber 10 for sealing the filter chamber 10. The filtered heat dissipation gas passes through the partition 19 and enters the electrical component installation area 9, so that larger particles or dust are prevented from entering the electrical component installation area 9 and affecting the normal use of the electrical components. At the same time, the heat dissipation device arranged inside the electrical component installation area 9, through the sliding heat storage device 13 and the track device, enables the heat storage and heat exchange plate 1303 to move in a certain direction. The electrical components in the electrical component installation area 9 store heat when dissipating heat. When the heat storage reaches a certain threshold, they can slide to the area of ​​the electrical component installation area 9 where the cooling air blows directly under the action of the control device. The area of ​​the electrical component installation area 9 where the cooling air blows directly is the through-hole on the partition or a position corresponding to the through-hole, so that the cooling air filtered by the filter chamber can directly blow the heat storage heat exchange plate 1303 after heat storage, so as to achieve rapid cooling and heat exchange of the heat storage heat exchange plate 1303 after heat storage. When the heat storage heat exchange plate 1303 returns to the low-temperature heat exchange temperature or its original shape, the heat storage heat exchange plate 1303 is cooled, and the sliding heat storage device 13 slides again to the area with higher temperature in the electrical component installation area 9 to further absorb the heat emitted by the electrical components in the electrical component installation area 9. The sliding heat storage device 13 can slide or be fixed at any position on the track device under the action of the control device.

[0071] The present invention has an ingenious structure. Under the condition that the cabinet sealing of the switch cabinet is relatively perfect, the electrical components in the cabinet 1 can be fully cooled, and the heat dissipation efficiency is high. The electrical component installation area 9 inside the cabinet 1 can be in a relatively stable temperature working range. At the same time, the dust removal effect can be guaranteed while the heat is dissipated, thereby solving the problems of heat dissipation and dust removal at the same time.

[0072] As an example of the present invention, the filter device 14 is a multi-level filter structure, and the filter device 14 can be fixed inside the filter chamber 10 in a pull-out manner. The air inlet of the filter device 14 is connected to the air supply pipe 6, and the air supply pipe 6 can supply air to the filter chamber 10 under the action of the air supply device 7. The air outlet of the filter device 14 is connected to the through-hole on the partition 19.

[0073] This arrangement improves the reliability of the filter device 14 in filtering dust and foreign matter by configuring the filter device 14 as a multi-level filter structure. The filter device 14 can be taken out by pulling out, which is convenient for cleaning, thereby enhancing the heat dissipation performance and dust removal performance of the switch cabinet described in the present invention.

[0074] As an example of the present invention, the filtering device 14 includes a first filter screen 1401, a second filter screen 1402, and a third filter screen 1403. The first filter screen 1401, the second filter screen 1402, and the third filter screen 1403 are arranged in sequence from top to bottom with gaps left. The first filter screen 1401, the second filter screen 1402, and the third filter screen 1403 form at least four air inlet areas through a sealing plate or a partition, including a first air inlet area A, a second air inlet area B, a third air inlet area C, and a fourth air inlet area D. The first air inlet area A is formed between the second filter screen 1402 and the third filter screen 1403. The first air inlet area A is a third filter hole on the third filter screen 1403. The air inlet area is an air inlet area after filtration by the second filter hole 14021 on the second filter plate 1402, and the air inlet area A of the first air inlet area can flow to the second air inlet area B through the connecting port on the partition, and the second air inlet area B is formed between the second filter plate 1402 and the third filter plate 1403. A third air inlet area C is formed above the second air inlet area B, and the third air inlet area C is formed between the second filter plate 1402 and the first filter plate 1401. The third air inlet area C is an air inlet area after filtration by the second filter hole 14021 on the second filter plate 1402, and the air in the first air inlet area A can flow to the fourth air inlet area D through the connecting port on the partition, and the air in the fourth air inlet area D can flow to the partition 19 through the first filter hole 14011 on the first filter plate 1401.

[0075] The present invention discloses a specific structure of a filter device 14, which makes full use of the space of the filter chamber 10. Without increasing the volume of the filter chamber 10, the cooling airflow entering the filter device 14 in the filter chamber 10 can enter the electrical component installation area 9 to dissipate heat for the electrical components after at least passing through multiple levels of filtration. On the one hand, the dust removal effect is guaranteed, and on the other hand, the heat dissipation airflow directly entering the electrical component installation area 9 is prevented from being too large, which affects the normal use of the electrical components.

[0076] As an example of the present invention, the filter device 14 is arranged in a rectangular shape, the first air inlet area A is formed near the middle of the filter device 14, the second air inlet area B, the third air inlet area C, and the fourth air inlet area D are arranged in pairs, and the two second air inlet areas B, the two third air inlet areas C, and the two fourth air inlet areas D are arranged in pairs along the central axis of the first air inlet area A.

Under normal working conditions, the air supply device 7 can be not started or maintained in a low-power working state, and a low air flow is input into the filter chamber 10, or the heat storage and heat exchange plate 1303 inside the electrical component installation area 9 is naturally cooled.
