Description

Technical Field

[0001] The present invention relates to the technical field of high and low voltage switch cabinets, and in particular to a high and low voltage switch cabinet for mining with intelligent temperature and humidity control. Background Art

[0002] As the name suggests, high and low voltage switchgear is a device that connects high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers to low-voltage cabinets, and then to distribution boxes for various power users. In mineral mines, due to the need to use a large number of electrical equipment, high and low voltage switchgear are generally installed in the mines to ensure normal power supply for construction in the mines.

[0003] When some existing high and low voltage switch cabinets are in use, the cooling and dehumidification operations inside the high and low voltage switch cabinets are generally completed directly through gas exchange inside and outside the cabinet. However, when the high and low voltage switch cabinets are used in mines, high temperature and high humidity environments, high temperature and low humidity environments, low temperature and high humidity environments, or low temperature and low humidity environments are prone to occur in mines. This may cause the temperature and humidity inside the high and low voltage switch cabinets to be too high or too low. The various components in the high and low voltage switch cabinets are operated in an unstable environment for a long time, which may reduce the service life of the various components in the high and low voltage switch cabinets, and the instability of temperature and humidity will also reduce the safety of the use of the high and low voltage switch cabinets.

[0038] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, there is provided a high and low voltage switchgear for mining with intelligent temperature and humidity control, comprising: a cabinet body 1, in which a partition 2 is fixedly installed, and an air pump 5 is provided between the partition 2 and the inner wall of the cabinet body 1, a rectangular hole 18 is opened on the top of the partition 2, and a cooling fin 6 is fixedly installed in the rectangular hole 18 via a connecting rod;

[0039] Frame 1 7 and frame 2 8 are symmetrically fixed by bolts and installed on both sides of the top of the cabinet 1, and the air pump 5 is located below frame 2 8. Water absorption plate 1 9 and water absorption plate 2 10 are fixedly installed therein, and the opposite ends of water absorption plate 1 9 and water absorption plate 2 10 are in contact and are both sleeved on the outer periphery of the refrigeration fin 6;

[0040] Several electrically controlled valves 11 and several electrically controlled valves 2 12 are fixedly installed at equal intervals through one side of the cabinet 1 and on the partition 2, and each electrically controlled valve 1 1 is symmetrically arranged with the corresponding electrically controlled valve 2 12. They are located above the frame 1 7. Several heat pipes 13 are fixedly installed at equal intervals through the other side of the top of the cabinet 1, and the interior of each heat pipe 13 is connected to the interior of the corresponding electrically controlled valve 2 12;

[0041] The drainage mechanism 3 is provided below the frame 2 8 and is used to guide the water in the cabinet 1 out of the cabinet 1;

[0042] The exhaust mechanism 4 is provided at the top of the cabinet 1 and is used for exhausting the gas in the cabinet 1 .

[0043] In this embodiment, when using the improved mining high and low voltage switchgear, please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, first, the refrigeration plate 6 is started. Since the cooling surface and the heat dissipation surface of the refrigeration plate 6 are attached to the water absorption plate 1 9 and the water absorption plate 2 10, the water absorption plate 1 9 and the water absorption plate 2 10 are respectively in a low temperature state and a high temperature state;

[0044] (Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, the partition 2 cooperates with the drainage mechanism 3 to divide the interior of the cabinet 1 into four parts, namely cavity 1 19, cavity 2 20, cavity 3 21 and cavity 4 22. The water absorption plate 1 9 is located in cavity 1 19, the water absorption plate 2 10 is located in cavity 4 22, and the vacuum circuit breaker and disconnector of the mining high and low voltage switch cabinet are located in cavity 2 20 and installed on the partition 2. The control host needs to be installed on the partition 2 to control the electronic control components such as the air pump 5, the electric control valve 1 11 and the electric control valve 2 12). Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, the air pump 5 is started to continuously extract the gas in the cavity 1 19 and the cavity 2 20 (the air pump 5 is a rotary vane vacuum pump), so that a slightly lower pressure state is formed in the cavity 2 20 and the cavity 3 21;

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, as the gas in cavity 20 and cavity 3 21 is lost, the control host controls the electric control valve 11 or the electric control valve 2 12 to open, and the external gas flows into cavity 19 through the electric control valve 11 and the electric control valve 2 12, and then flows into cavity 3 21 after passing through the holes of water absorption plate 1 9 to replenish the gas lost in cavity 3 21. During the process of the gas passing through the holes of water absorption plate 1 9, the temperature of the gas decreases due to the contact between the gas and the water absorption plate 1 9, forming low-temperature gas, and most of the water vapor in the gas condenses into water droplets and is absorbed by the water absorption plate 1 9;

[0046] It should be noted that during the process of the gas in cavity 19 flowing into cavity 2 20 , the gas in cavity 4 22 will hardly flow into cavity 1 19 through rectangular hole 18 due to the blocking of rectangular hole 18 by the cooling plate, water absorption plate 1 9 and water absorption plate 2 10 .

[0047] After the low-temperature gas flows into the cavity three 21, it flows downward and mixes with the gas in the cavity three 21 to reduce the temperature in the cavity three 21 and cool the various components in the mine high and low pressure switch. As the low-temperature gas absorbs the heat emitted by the various components, the low-temperature gas becomes a high-temperature gas with a slightly higher temperature. Then the high-temperature gas bypasses the partition 2 and flows into the cavity three 21 to be sucked by the air pump 5, and is then injected into the cavity four 22 by the air pump 5. There is a pressure difference between the upper and lower sides of the frame two 8, and the high-temperature gas flows upward. When the high-temperature gas passes through the holes of the water absorption plate two 10, the heat emitted by the heat dissipation surface of the refrigeration plate 6 is used to absorb the water. The water plate 2 10 is heated to make the water in the water absorption plate 2 10 evaporate into water vapor more quickly. As the high-temperature gas flows upward, the evaporated water vapor is quickly taken out of the water absorption plate 2 10 to form a mixed gas, which is discharged from the cabinet 1 through the exhaust mechanism 4. The mixed gas with a high temperature and high water vapor content is sprayed around the high and low voltage switch cabinets for mining. As the temperature of the mixed gas decreases, part of the water vapor in the gas condenses into small water droplets and adheres to the dust in the air around the high and low voltage switch cabinets for mining, increasing the weight of the dust so that the dust falls to the ground, thereby reducing the dust content in the air around the high and low voltage switch cabinets for mining;

[0048] As the water in the second absorbent plate 10 evaporates, it can quickly remove the heat from the cooling plate's heat dissipation surface, thereby simultaneously completing the cooling process of the cooling plate. At the same time, as the water in the second absorbent plate 10 evaporates, the wetness of the second absorbent plate 10 becomes much lower than that of the first absorbent plate 9. At this time, due to the large number of interconnected micro-pores or fiber gaps on the first absorbent plate 9 and the second absorbent plate 10, a porous structure is formed, which forms spontaneous infiltration. In other words, the water in the first absorbent plate 9 quickly flows into the second absorbent plate 10 by capillary action, thereby replenishing the water lost in the second absorbent plate 10.

[0049] It should be noted that when the external gas passes through the electric-controlled valve 11 and flows into the cavity 19, it is a room-temperature gas. When the external gas passes through the electric-controlled valve 2 12 and flows into the cavity 19, it will first pass through the heat-conducting pipe 13 and perform heat exchange with the high-temperature gas flowing in the cavity 4 22 through the heat-conducting pipe 13, thereby heating the gas flowing into the cavity 19. When the gas is discharged from the electric-controlled valve 11 and the electric-controlled valve 2 12, due to the relative position of the electric-controlled valve 11 and the electric-controlled valve 2 12, the gases discharged from the electric-controlled valve 11 and the electric-controlled valve 2 12 have different temperatures. Since the airflow has mass, the change in the airflow motion state needs to overcome inertia, that is, the gas diffuses outward or changes flow direction. Therefore, the gases discharged from the electric-controlled valve 11 and the electric-controlled valve 2 12 with different temperatures will first collide with each other, perform preliminary counter-mixing, and then diffuse outward, and finally flow into the holes of the water-absorbing plate 1 9.

[0050] In summary, by controlling the opening degree of the electric-controlled valve 11 and the electric-controlled valve 2 12 by the control host, the mixing ratio between the two can be adjusted to adjust the temperature of the air flowing into the cavity 19, the temperature of the gas flowing into the cavity 2 20 can be adjusted in conjunction with the operating power of the refrigeration plate 6, and the temperature environment in the cavity 3 21 can be adjusted in conjunction with the operating power of the air pump 5. The control host can intelligently adjust the temperature in the mine high and low voltage switch cabinet according to the monitoring data of the temperature and humidity sensors provided in the mine high and low voltage switch cabinet, and the dehumidification and cooling effects are good.

[0051] When the high and low voltage switch cabinets for mining are used, when high-intensity dehumidification is required but high-intensity cooling treatment is not required (similar to the situation on foggy days), the control host increases the operating power of the refrigeration plate 6 and increases the amount of gas flowing into the electric control valve 2 12. In conjunction with the adjustment of the operating power of the air pump 5, the high-intensity dehumidification operation of the air can be performed through the extremely low temperature water absorption plate 19 while the low-intensity cooling treatment of the high and low voltage switch cabinets for mining is being performed. If part of the water drips from the water absorption plate 9 due to the high humidity of the water absorption plate 9, the water dripping from the water absorption plate 9 is guided out of the cabinet body 1 by the drainage mechanism 3. The control host can intelligently adjust the humidity in the high and low voltage switch cabinets for mining according to the monitoring data of the temperature and humidity sensors provided in the high and low voltage switch cabinets for mining;

[0052] During the use of this improved mine high and low voltage switchgear, the dehumidification intensity and cooling intensity in the mine high and low voltage switchgear can be intelligently adjusted according to the high temperature and high humidity environment, high temperature and low humidity environment, low temperature and high humidity environment or low temperature and low humidity environment in the mine, so that the various components in the mine high and low voltage switchgear can operate in a suitable temperature environment for a long time, thereby extending the service life of the mine high and low voltage switchgear and making the use of the mine high and low voltage switchgear safer.

[0053] In a further preferred embodiment of the present invention, Figure 2 、 Figure 3 and Figure 8 As shown, the partition 2 is L-shaped, and two filter mechanisms 14 are fixedly installed on the outer wall of the top of the cabinet 1 at the positions corresponding to the electric control valve 1 11 and the electric control valve 2 12, respectively, for filtering impurities in the gas flowing into the electric control valve 1 11 and the electric control valve 2 12;

[0054] In this embodiment, please refer to Figure 2 and Figure 8As shown, (the filtering mechanism 14 includes a storage box, which is fixedly mounted on the outer wall of the cabinet body 1, and the interior of the electric-controlled valve 11 and the interior of the electric-controlled valve 2 12 are respectively connected to the interiors of the two storage boxes, a filter element is slidably mounted in the storage box, and a box cover in a ring shape is fixedly mounted in the top opening of the storage box by a snap-fit ​​structure such as bolts or buckles), before the external air flows into the electric-controlled valve 1 11 or the electric-controlled valve 2 12, it will first pass through the holes of the filter element, and the filter element can filter out impurities such as dust or particulate matter in the air, so as to prevent impurities in the mine from entering the mine high and low voltage switch cabinet along with the air flow, and adhering to various components in the mine high and low voltage switch cabinet, affecting the operation and use of the mine high and low voltage switch cabinet;

[0055] The L-shaped partition 2 allows the gas entering the second cavity 20 to tilt away from the partition 2 during its downward flow.

[0056] In a further preferred embodiment of the present invention, Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a plurality of heat-conducting mesh plates 15 and 16 are fixedly installed on the cooling surface and the heat-dissipating surface of the refrigeration fin 6 at equal intervals, and the heat-conducting mesh plates 15 and 16 are slidably installed in the water-absorbing plate 1 9 and the water-absorbing plate 2 10, respectively. The mesh holes on the heat-conducting mesh plate 15 are irregular perforations that are randomly distributed and interconnected, and the mesh holes on the heat-conducting mesh plate 2 16 are circular holes.

[0057] In this embodiment, please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, during the operation of the refrigeration plate 6, the water absorption plate 9 quickly exchanges heat with the cooling surface of the refrigeration plate 6 through the heat conductive mesh plate 15 with good heat conductivity, so that the refrigeration plate 6 can quickly reduce the temperature of the water absorption plate 9 during operation, and when the air passes through the holes of the water absorption plate 9, it will simultaneously pass through the mesh of the heat conductive mesh plate 15, and the irregular arrangement of the mesh can make the air fully contact with the heat conductive mesh plate 15, and with the lower temperature of the heat conductive mesh plate 15, it can enhance the condensation effect of water vapor in the air on the water absorption plate 9.

[0058] The water absorption plate 2 10 simultaneously exchanges heat quickly with the heat dissipation surface of the refrigeration plate 6 through the heat conductive mesh plate 2 16 with good thermal conductivity, so that the heat emitted from the heat dissipation surface of the refrigeration plate 6 can be quickly transferred to the water absorption plate 2 10 for the water in the water absorption plate 2 10 to absorb the heat. In addition, when the high-temperature gas passes through the holes on the water absorption plate 2 10, it can pass through the circular holes on the heat conductive mesh plate 2 16 more quickly, so as to avoid the setting of the heat conductive mesh plate 2 16 excessively affecting the passage of the high-temperature gas in the mesh of the heat conductive mesh plate 2 16.

[0059] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 and Figure 4 As shown, the outer peripheral walls of frame 1 7 and frame 2 8 are in contact with the inner wall of cabinet 1 and the side wall of partition 2, and sealing gaskets 17 are fixedly installed in the plate walls of frame 1 7 and frame 2 8 to block the gaps between frame 1 7 and frame 2 8 and the inner wall of cabinet 1 and the side wall of partition 2;

[0060] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 As shown, the water absorption plate 1 9 and the water absorption plate 2 10 can be stably supported by the frame 1 7 and the frame 2 8, so that the water absorption plate 1 9 and the water absorption plate 2 10 are stably maintained in a straight state in the cabinet 1;

[0061] When replacing the water absorption plate 1 9 or the water absorption plate 2 10, the bolts on the frame 1 7 or the frame 2 8 are unscrewed, and then the frame 1 7 or the frame 2 8 is directly pulled out from the cabinet 1 to complete the removal of the water absorption plate 1 9 or the water absorption plate 2 10. Then, a new water absorption plate 1 9 or the water absorption plate 2 10 is replaced, reinserted into the cabinet 1 and fixed to the frame 1 7 or the frame 2 8 and the cabinet 1 again with the bolts to complete the replacement of the water absorption plate 1 9 or the water absorption plate 2 10. The operation is relatively simple.

[0062] During the process of inserting the water absorption plate 1 9 or the water absorption plate 2 10 into the cabinet 1 , the heat conduction mesh plate 1 15 or the heat conduction mesh plate 2 16 is simultaneously inserted into the water absorption plate 1 9 or the water absorption plate 2 10 , and the water absorption plate 1 9 or the water absorption plate 2 10 is supported by the inside of the water absorption plate 1 9 or the water absorption plate 2 10 so that the water absorption plate 1 9 or the water absorption plate 2 10 remains in a straight state when inserted into the rectangular hole 18, and the opposite end of the water absorption plate 1 9 or the water absorption plate 2 10 is directly put on the refrigeration plate to complete the fitting of the water absorption plate 1 9 and the water absorption plate 2 10.

[0063] In a further preferred embodiment of the present invention, Figure 2 and Figure 3As shown, the drainage mechanism 3 includes a guide plate 31, which is arranged in an inclined shape and fixedly installed in the cabinet 1. The exhaust port of the partition 2 and the air pump 5 are fixed through the guide plate 31. A plurality of guide holes 32 are fixedly installed at equal intervals through the position of the partition 2 corresponding to the guide plate 31. A plurality of pressure-limiting valves 33 are fixedly installed at equal intervals through the position of the guide plate 31 on the other side of the top of the cabinet 1.

[0064] In this embodiment, please refer to Figure 2 and Figure 3 As shown, when water drops from the water absorption plate 9, it falls directly onto the guide plate 31, then flows along the inclined guide plate 31, passes through the guide hole 32, crosses the partition 2 and gathers at the pressure limiting valve 33, and the gas injected into the cavity 22 by the air pump 5, due to the limited amount of gas passing through the holes of the water absorption plate 210, most of the gas injected into the cavity 22 by the air pump 5 passes through the holes of the water absorption plate 210 and continues to flow upward, while a very small amount of gas is retained on the bottom side of the water absorption plate 210, so that a state of slightly higher air pressure is formed between the bottom side of the water absorption plate 210 and the partition 2, the guide plate 31 and the inner wall of the cabinet 1, so that a sufficient pressure difference is formed at both ends of the pressure limiting valve 33, so that a very small amount of gas passes through the pressure limiting valve 33 and is discharged from the cabinet 1, and when there is water at the pressure limiting valve 33, the water is pushed through the pressure limiting valve 33 to be discharged.

[0065] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the guide hole 32 is arranged in an inclined shape, and a one-way valve 34 is fixedly installed in the guide hole 32, and the bottom ends of the openings at both ends of the one-way valve 34 are coplanar with the top side of the guide plate 31;

[0066] In this embodiment, please refer to Figure 2 and Figure 3 As shown, when water flows into the guide hole 32, as the water level rises, a pressure difference is formed at both ends of the one-way valve 34, so that water can directly pass through the one-way partition 2. In the process of the air pump 5 injecting gas into the cavity four 22, due to the limited amount of gas passing through the holes of the water absorption plate 2 10, most of the gas injected into the cavity four 22 by the air pump 5 continues to flow upward through the holes of the water absorption plate 2 10, while a very small amount of gas is retained on the bottom side of the water absorption plate 2 10, so that a slightly higher air pressure state is formed between the bottom side of the water absorption plate 2 10 and the partition 2, the guide plate 31 and the inner wall of the cabinet 1. Then, due to the obstruction of the one-way valve 34, the gas will not flow between the water absorption plate 1 9 and the guide plate 31, affecting the cooling and dehumidification effect of the high and low voltage switch cabinet for mining.

[0067] In a further preferred embodiment of the present invention, Figure 2 、 Figure 6 and Figure 7As shown, a plurality of fixed cylinders 35 are evenly spaced through the partition 2, and the fixed cylinders 35 are located below the frame 7. A plurality of air inlet holes 36 are evenly spaced on the outer peripheral wall of the top of the fixed cylinder 35. The air inlet holes 36 are arranged in an S shape and are located above the guide plate 31.

[0068] In this embodiment, please refer to Figure 2 and Figure 6 As shown, when the gas in cavity 19 flows to the position of the guide plate 31, it flows into the fixed cylinder 35 from the air inlet 36, then flows along the fixed cylinder 35 to cross the guide plate 31, and finally flows into cavity 2 20. When the high and low voltage switchgear for mining is subjected to high-intensity dehumidification operation, since the air inlet 36 is S-shaped, that is, it is tilted downward as a whole, when the water droplets fall, if the water droplets move into the air inlet 36 along with the gas, the movement trajectory of the water droplets themselves needs to be changed, and the change in the movement trajectory of the water droplets needs to overcome their own inertia, and the water droplets move downward at a faster rate, which makes the water droplets directly pass over the air inlet, thereby preventing the gas from bringing the water droplets into the fixed cylinder 35 when entering the air inlet 36, affecting the use of the device.

[0069] In a further preferred embodiment of the present invention, Figure 2 、 Figure 6 and Figure 7 As shown, the fixed cylinder 35 is rotatably connected to the partition 2 through a bearing, and an impeller 37 is fixedly installed in the bottom opening of the fixed cylinder 35 through a connecting rod;

[0070] In this embodiment, (please refer to Figure 6 As shown, a sealing ring is installed on the outer peripheral side of the fixed cylinder 35 to seal the gap between the fixed cylinder 35 and the guide plate 31). Figure 2 and Figure 7As shown, when the gas is discharged from the bottom opening of the fixed cylinder 35, the gas continues to blow on the impeller 37, thereby continuously applying an axial driving force to the fixed cylinder 35, so that the fixed cylinder 35 rotates rapidly in the guide plate 31. When a large number of water droplets drip from the water absorption plate 9, if the gas brings a very small amount of water droplets into the air inlet 36, due to the curvature of the air inlet 36, when the water droplets move in the air inlet 36, they need to change their own movement trajectory many times according to the curved shape of the air inlet 36. The change of the water droplet movement trajectory requires overcoming its own inertia. When the water droplets follow the gas in the air inlet 36, they will collide with the gas. The moving trajectory deviates, and the water droplets will directly contact the inside of the air inlet hole 36 and adhere to the inner wall of the air inlet hole 36. As the fixed cylinder 35 rotates, the water droplets fit into the inner wall of the air inlet hole 36 and adhere to the inner wall of the air inlet hole 36, and rotate with the fixed cylinder 35. At this time, due to the centrifugal force when the water droplets rotate, as the fixed cylinder 35 rotates, the water droplets slide along the curved inner arc wall of the air inlet hole 36 and directly slide out of the air inlet hole 36, thereby throwing the water entering the air inlet hole 36 to the outer peripheral side of the fixed cylinder 35. This can prevent the gas from bringing water droplets into the fixed cylinder 35 when the high and low voltage switchgear for mining is performing high-intensity dehumidification operations.

[0071] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the exhaust mechanism 4 includes an exhaust tube 41, which is provided at the top of the cabinet 1, and the interior of the exhaust tube 41 is communicated with the interior of the cabinet 1. The exhaust tube 41 is located above the heat conducting pipe 13, and the top of the exhaust tube 41 is hemispherical, and a plurality of exhaust holes 42 are evenly spaced on the arc wall of the exhaust tube 41;

[0072] In this embodiment, please refer to Figure 1 and Figure 2 As shown, after the high-temperature gas brings out the water vapor in the water absorption plate 2 10 to form a mixed gas, it directly flows into the exhaust pipe 41, and is then discharged from the top side of the cabinet 1 to the surrounding areas through the exhaust hole 42, so that the gas with a higher temperature and more water vapor is directly scattered into the air around the cabinet 1. As the temperature of the mixed gas decreases, part of the water vapor in the gas condenses into small water droplets and adheres to the dust in the air around the high and low voltage switch cabinets for mining, increasing the weight of the dust so that the dust falls to the ground, thereby reducing the dust content in the air around the high and low voltage switch cabinets for mining.

[0073] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the exhaust pipe 41 is rotatably connected to the cabinet body 1 through a bearing, and the bottom opening of the exhaust hole 42 is fixedly equipped with an impeller 43 through a support rod;

[0074] In this embodiment, (please refer to Figure 8 As shown, the outer peripheral side of the exhaust pipe 41 is equipped with a sealing ring to block the gap between the exhaust pipe 41 and the cabinet 1). Figure 1 、 Figure 2 and Figure 9 As shown, in the process of the mixed gas flowing into the exhaust pipe 41, it continuously blows on the impeller 2 43, thereby continuously applying an axial driving force to the exhaust pipe 41 through the impeller 2 43, so that the exhaust pipe 41 rotates rapidly, thereby constantly changing the position of the exhaust hole 42 to expand the coverage of the mixed air and enhance the dust removal effect of the air around the high and low voltage switchgear for mining.

[0075] Working principle: When the improved mining high and low voltage switch cabinet is in use, the controller adjusts the amount of gas flowing into the cavity 19 at the electric control valve 11 and the electric control valve 2 12 to control the temperature of the gas flowing into the cavity 19, cooperates with the operating power of the refrigeration plate 6 and the air pump 5, and reduces the humidity and temperature of the gas flowing into the cabinet 1 by condensation. After completing the cooling treatment of the various components of the mining high and low voltage switch cabinet, the condensed water is re-vaporized and discharged through the heat dissipated by the various components of the mining high and low voltage switch cabinet and the heat dissipated by the refrigeration plate 6, so that the mining high and low voltage switch cabinet can be intelligently adjusted to the dehumidification intensity and cooling intensity in the mining high and low voltage switch cabinet according to the high temperature and high humidity environment, high temperature and low humidity environment, low temperature and high humidity environment or low temperature and low humidity environment in the mine, so that the various components in the mining high and low voltage switch cabinet are located in a suitable temperature environment for a long time.

[0076] The above-mentioned gas with high temperature and humidity discharged from the cabinet body 1 is directly sprayed into the air around the cabinet body 1 when it is discharged from the cabinet body 1, so as to increase the weight of the impurities by adsorbing and bonding the condensed water droplets with impurities such as dust or particulate matter in the air, thereby reducing the dust content of the air around the high and low voltage switch cabinet for mining, so as to avoid a large amount of impurities flowing into the filter mechanism 14 with the gas and affecting the use of the device.
