Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to an intelligent dehumidification and heat dissipation type high and low voltage switch cabinet. Background Art

[0002] As an indispensable component of power systems, domestic high and low voltage switchgear is widely used in industrial, commercial, and civil fields. With the growth of power demand and the complexity of power systems, the performance requirements of switchgear are also constantly improving.

[0003] Traditional switchgear faces challenges in high-temperature and humid environments. The electrical components within the switchgear generate significant heat during operation. Traditional switchgear heat dissipation methods are typically simple and lack intelligent control mechanisms, making it impossible to adjust the heat dissipation intensity in real time based on actual temperature fluctuations within the switchgear. This prevents heat from being dissipated effectively and promptly, leading to continuously rising temperatures inside the switchgear. This not only accelerates the aging of electrical components, reducing their performance and reliability, but can also cause overheating failures, unstable power system operation, and even safety incidents. Humid environments are the natural enemy of electrical equipment. Traditional switchgear primarily relies on simple sealing structures and desiccants for dehumidification, but these measures are inadequate in high-humidity environments. Moisture easily penetrates the switchgear through gaps, condensing into water droplets that adhere to the surfaces of electrical components, degrading insulation performance and increasing the risk of short circuits and leakage. Long-term moisture exposure can also cause rust and corrosion of metal components, compromising the stability of the switchgear's mechanical structure and electrical connections, further reducing its service life and operational safety. Therefore, we propose an intelligent dehumidification and heat dissipation high- and low-voltage switchgear to address this problem. Summary of the Invention

[0024] The beneficial effects of the present invention are:

[0025] 1. In the present invention, the intelligent dehumidification and heat dissipation type high and low voltage switch cabinet can achieve sealing of the switch cabinet through the cooperation of the cabinet door and the sealing strip. The ventilation frame and dustproof net can facilitate the entry of natural wind into the cabinet to take away the internal heat and achieve heat dissipation. The temperature and humidity inside the cabinet are monitored by temperature sensors and humidity sensors. When the temperature sensor detects that the temperature rises, the controller controls the fan to start, so that the outside air enters the cabinet through the ventilation frame at the bottom of one side of the cabinet, and then is discharged from the ventilation frame at the top of the other side of the cabinet. When flowing through the cabinet, it takes away the heat, thereby achieving the effect of forced ventilation to enhance heat dissipation. When the temperature is detected to be higher, the controller controls the fan power to increase, thereby increasing the ventilation volume to increase the heat dissipation rate. During the ventilation process, the desiccant in the drying box absorbs moisture, thereby achieving the effect of dehumidifying the solid.

[0026] 2. In the present invention, the intelligent dehumidification and heat dissipation high and low voltage switchgear described above monitors the temperature difference between the two sides of the cabinet body through temperature sensors on both sides, and controls the activation of the electric push rod according to the temperature difference, thereby driving the connection frame to move up and down. The connection frame drives the rotation of multiple connection arms through cooperation with the connection column, thereby driving the swing blades to rotate through the rotating shaft, thereby changing the direction and speed of the airflow inside the cabinet body, and realizing efficient and uniform heat dissipation inside the cabinet body;

[0027] 3. In the present invention, the intelligent dehumidification and heat dissipation type high and low voltage switch cabinet described above, when the humidity sensor detects that the humidity inside the cabinet is too high, starts the drive motor and the condensation rod, the drive motor drives the crankshaft to rotate, and the drive shaft drives the piston plate to move back and forth left and right through the cooperation with the connecting plate, the movable plate and the guide rail. During the movement of the piston plate to the left, the air in the cabinet enters the condensation box through the air inlet pipe and the one-way valve therein, and the condensation rod cools the air inside the cabinet, so that the water vapor in the gas condenses and condenses on the surface of the condensation rod, and the piston plate drives the sealing cylinder to move synchronously through the linkage frame. When the sealing cylinder is sleeved on the outside of the air inlet pipe, the air intake of the air inlet pipe is blocked, and the piston plate continues to move to the left, the air pressure inside the condensation box is reduced. According to Dalton's law of partial pressure, reducing the pressure of non-condensable gas can reduce the partial pressure of water vapor, thereby increasing the condensation rate of moisture, making it easier for water vapor to reach a saturated state and condense, and the condensed water flows downward along the condensation rod and drips into the water collecting frame;

[0028] 4. In the present invention, the intelligent dehumidification and heat dissipation type high and low voltage switch cabinet drives the rotating plate to rotate through the crankshaft, and drives the two sleeve plates to perform circular motion. The sleeve plates move to the side away from each other under the action of centrifugal force, and drive the connecting shaft and the U-shaped frame to move downward through the cooperation with the bending frame. The U-shaped frame drives the connecting plate and the gate plate to move to the right through the linkage rod, so that the gate plate seals the water outlet, avoiding the linkage between the condensation box and the water collecting box during the condensation process and affecting the negative pressure control of the condensation box. At the same time, the connecting plate squeezes the varistor through the compression spring, thereby reducing the resistance value of the varistor. Since it is connected in series with the condensation rod, the power of the condensation rod increases, and the humidity sensor monitors the cabinet body. The lower the humidity inside, the faster the output shaft speed of the driving motor controlled by the controller is, so that the squeezing force on the varistor is greater, thereby making the power of the condensation rod greater, so as to improve the condensation effect, thereby achieving the dehumidification effect. After the dehumidification is completed, the driving motor is controlled by the controller to stop running, and the connecting plate is reset under the action of the compression spring, so that the water outlet is opened, and the condensed water flows into the water collecting tank for storage. When the temperature inside the cabinet is too high, the sealing plate is driven to move horizontally by starting the electric push rod, so that the condensed water is discharged from the water outlet, and flows repeatedly in the inclined plate and the inclined frame, and evaporates and absorbs heat, thereby cooling the inclined frame and the condensation frame, thereby further improving the heat dissipation of the cabinet.

[0029] 5. In the present invention, the intelligent dehumidification and heat dissipation type high and low voltage switch cabinet sends the monitored temperature and humidity values ​​to a remote client through a signal transmitter, and receives the remote operation signal through a signal receiver, thereby facilitating remote monitoring. When the temperature or humidity is too high, the controller controls the alarm to activate, thereby achieving early warning. By pulling the pull plate upward and driving the two card plates closer together through two pull ropes, the card plates are disengaged from the card slots, releasing the fixation to the top plate. Then, the handle is pulled upward to remove the baffle, thereby allowing the drying box to be taken out for convenient replacement of the desiccant.

[0030] 6. In the present invention, the intelligent dehumidification and heat dissipation type high and low voltage switch cabinet can achieve forced ventilation through the set ventilation mechanism, adjust the ventilation speed according to the temperature, and change the air flow direction in the switch cabinet as needed to achieve uniform and controllable heat dissipation. The set condensation mechanism can achieve dehumidification and heat dissipation at the same time, and use condensed water for further heat dissipation to improve the dehumidification and heat dissipation effect.

When the temperature sensor 11 detects that the temperature rises, the controller 10 controls the fan 210 to start, so that the outside air enters the cabinet 1 through the ventilation frame 201 at the bottom of one side of the cabinet 1, and then is discharged from the ventilation frame 201 at the top of the other side of the cabinet 1, taking away the heat when flowing through the interior of the cabinet 1, thereby achieving the effect of forced ventilation to enhance heat dissipation, and when the monitored temperature is higher, the controller 10 controls the fan 210 to increase its power, thereby increasing the ventilation volume to increase the heat dissipation rate, and during the ventilation process, the desiccant in the drying box 502 absorbs moisture, thereby having a dehumidifying effect on the solid;

[0071] The temperature difference between the two sides of the cabinet 1 is monitored by the temperature sensors 11 on both sides, and the electric push rod 209 is controlled to start according to the temperature difference, thereby driving the connection frame 206 to move up and down. The connection frame 206 drives the multiple connection arms 204 to rotate by cooperating with the connection column 205, thereby driving the swing blades 202 to rotate through the rotating shaft 203, thereby changing the direction and speed of the airflow inside the cabinet 1, and achieving efficient and uniform heat dissipation inside the cabinet 1;

[0072] When the humidity sensor 23 detects that the humidity inside the cabinet 1 is too high, the drive motor 610 and the condensation rod 604 are started, and the drive motor 610 drives the crankshaft 609 to rotate. The drive shaft drives the piston plate 605 to move back and forth left and right through the cooperation with the connecting plate 608, the movable plate 607 and the guide rail 606. During the movement of the piston plate 605 to the left, the air in the cabinet 1 enters the condensation box 601 through the air inlet pipe 602 and the one-way valve 9 therein, and the condensation rod 604 cools the air inside the cabinet 1, so that the water vapor in the gas condenses and condenses on the condensation rod. On the surface of 604, the piston plate 605 drives the sealing cylinder 611 to move synchronously through the linkage frame 612. When the sealing cylinder 611 is sleeved on the outside of the intake pipe 602, it blocks the air intake of the intake pipe 602. When the piston plate 605 continues to move to the left, the air pressure inside the condensation box 601 decreases. According to Dalton's law of partial pressures, reducing the pressure of non-condensable gases can reduce the partial pressure of water vapor, thereby increasing the condensation rate of moisture, making it easier for water vapor to reach saturation and condense. The condensed water flows downward along the condensation rod 604 and drips into the water collection frame.

[0073] The crankshaft 609 drives the rotating plate 19 to rotate, and drives the two sleeve plates 17 to perform circular motion. The sleeve plates 17 move to the side away from each other under the action of centrifugal force, and drive the connecting shaft 16 and the U-shaped frame 15 to move downward through the cooperation with the bending frame 18. The U-shaped frame 15 drives the connecting plate 13 and the gate plate 12 to move to the right through the linkage rod, so that the gate plate 12 seals the water outlet to avoid the linkage between the condensation box 601 and the water collecting box 701 during the condensation process, affecting the negative pressure control of the condensation box 601. At the same time, the connecting plate 13 squeezes the varistor 22 through the compression spring 21, thereby reducing the resistance value of the varistor 22. Since it is connected in series with the condensation rod 604, the power of the condensation rod 604 increases, and the humidity sensor 23 detects that the lower the humidity in the cabinet 1, the better. , the faster the output shaft speed of the driving motor 610 is controlled by the controller 10, the greater the squeezing force on the varistor 22 is, and thus the power of the condensation rod 604 is greater, so as to improve the condensation effect, thereby achieving the dehumidification effect. After the dehumidification is completed, the driving motor 610 is controlled by the controller 10 to stop running, and the connecting plate 13 is reset under the action of the compression spring 21, so that the water outlet is opened, and the condensed water flows into the water collecting tank 701 for storage. When it is necessary to adjust the internal temperature of the cabinet 1 to be too high, the sealing plate is driven to move horizontally by starting the electric push rod 209, so that the condensed water is discharged from the water outlet, and repeatedly flows in the inclined plate 804 and the inclined frame 801, and evaporates and absorbs heat, thereby cooling the inclined frame 801 and the condensation frame, thereby further improving the heat dissipation of the cabinet 1;

[0074] The monitored temperature and humidity values ​​are sent to a remote client via the signal transmitter 402, and the remote operation signal is received via the signal receiver 401, thereby facilitating remote monitoring. When the temperature or humidity is too high, the controller 10 controls the alarm 403 to start, thereby providing an early warning. By pulling the pull plate 509 upward and driving the two card plates 505 closer to each other via the two pull ropes 507, the card plates 505 are disengaged from the card slots, releasing the fixation on the top plate 501, and then pulling the handle 510 upward to remove the baffle, the drying box 502 can be taken out to facilitate the replacement of the desiccant.

[0075] like Figure 15 As shown, when the humidity in the cabinet 1 is too high, it means that the outside air temperature is too high. At this time, the controller 10 controls the electric push rod 209 to drive the connecting frame 206 to move downward, so that the multiple swing blades 202 fit together to achieve the closure of the ventilation frame 201, thereby avoiding the influence of external moisture, and then the initialization and heat dissipation inside the cabinet 1 are achieved by separately starting the condensing mechanism 6.
