Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and particularly to an intelligent dehumidifying and heat-dissipating type high and low voltage switch cabinet. Background Art

[0002] Domestic high and low voltage switch cabinets, as indispensable equipment in the power system, are widely used in industrial, commercial, and civil fields. With the growth of power demand and the complexity of the power system, the performance requirements for switch cabinets are also constantly increasing.

[0003] Problems of traditional switch cabinets in high-temperature and humid environments: During operation, electrical components inside the switch cabinet generate a large amount of heat. The heat dissipation method of traditional switch cabinets is usually relatively single and lacks an intelligent control mechanism, unable to adjust the heat dissipation intensity in real time according to the actual temperature change inside the cabinet. This results in the heat not being able to be discharged outside the cabinet in a timely and effective manner, and the temperature inside the cabinet continues to rise. This will not only accelerate the aging of electrical components, reduce their performance and reliability, but may also cause overheating faults, leading to unstable operation of the power system and even safety accidents. The humid environment is the "natural enemy" of electrical equipment. Traditional switch cabinets mainly rely on simple sealing structures and desiccants for dehumidification, but these measures are ineffective in the face of high humidity environments. Moisture easily invades the cabinet through gaps and condenses into water droplets adhering to the surface of electrical components, resulting in a decrease in insulation performance and an increased risk of short circuits and electric leakage. Long-term moisture exposure will also cause metal parts to rust and corrode, affecting the mechanical structure of the switch cabinet and the stability of electrical connections, further reducing the service life and operating safety of the switch cabinet; Therefore, we propose an intelligent dehumidifying and heat-dissipating type high and low voltage switch cabinet to solve this problem.

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

[0025] 1. In the present invention, for the intelligent dehumidifying and heat dissipating high and low voltage switchgear, the cooperation between the cabinet door and the sealing strip can realize the sealing of the switchgear. By providing the ventilation frame and the dust-proof net, natural wind can conveniently enter the interior of the cabinet body to take away the internal heat and achieve heat dissipation. The temperature and humidity inside the cabinet body are monitored by the temperature sensor and the humidity sensor. When the temperature sensor monitors that the temperature rises, the controller controls the fan to start, so that the outside air enters the interior of the cabinet body through the ventilation frame at the bottom of one side of the cabinet body, and then discharges from the ventilation frame at the top of the other side of the cabinet body. When flowing through the interior of the cabinet body, the heat is taken away, so as to achieve the effect of forced ventilation and enhanced heat dissipation. Moreover, when the monitored temperature is higher, the power of the fan is controlled by the controller to increase, so as to increase the ventilation volume and improve the heat dissipation rate. During the ventilation process, the desiccant in the drying box absorbs moisture, so as to achieve the effect of dehumidifying the solid.

[0026] 2. In the present invention, for the intelligent dehumidifying and heat dissipating high and low voltage switchgear, the temperature difference between the two sides inside the cabinet body is monitored by the temperature sensors on both sides, and the electric push rod is controlled to start according to the temperature difference, so as to drive the connecting frame to move up and down. The connecting frame drives a plurality of connecting arms to rotate through the cooperation with the connecting column, so as to drive the swing blades to rotate through the rotating shaft, so as to change the air flow direction and speed inside the cabinet body and achieve efficient and uniform heat dissipation inside the cabinet body.

[0027] 3. In the present invention, for the intelligent dehumidifying and heat-dissipating high- and low-voltage switchgear cabinet, when the humidity sensor detects that the humidity inside the cabinet is too high, the driving motor and the condensation rod are started. The driving motor drives the crankshaft to rotate, and the driving shaft drives the piston plate to move left and right reciprocally through the cooperation with the connecting plate, the moving plate and the guide rail. During the leftward movement of the piston plate, the air inside the cabinet enters the condensation box through the air inlet pipe and the one-way valve therein. The condensation rod cools the air inside it, causing the water vapor in the gas to condense and accumulate on the surface of the condensation rod. The piston plate drives the sealing cylinder to move synchronously through the linkage frame. When the sealing cylinder sleeves outside the air inlet pipe, the air intake of the air inlet pipe is blocked. When the piston plate continues to move leftward, the air pressure inside the condensation box 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 and making it easier for water vapor to reach the saturation state and condense. The condensed water flows downward along the condensation rod and drips into the water collection frame;

[0028] 4. In the present invention, for the intelligent dehumidifying and heat-dissipating high- and low-voltage switchgear cabinet, the crankshaft drives the rotating plate to rotate, and drives the two sleeve plates to perform circular motion. Under the action of centrifugal force, the sleeve plates move away from each other, and drive the connecting shaft and the U-shaped frame to move downward through the cooperation with the bent frame. The U-shaped frame drives the connecting plate and the gate plate to move rightward through the linkage rod, so that the gate plate seals the water outlet hole, avoiding the linkage between the condensation box and the water collection tank 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. Moreover, the lower the humidity inside the cabinet detected by the humidity sensor, the faster the output shaft speed of the driving motor is controlled by the controller, so that the squeezing force on the varistor is greater, and thus the power of the condensation rod is greater, to improve the condensation effect and achieve the dehumidification effect. After the dehumidification is completed, the controller controls the driving motor to stop running, and the connecting plate resets under the action of the compression spring, so that the water outlet hole is opened, and the condensed water flows into the water collection tank for storage. When it is necessary to cool the inside of the cabinet when the temperature is too high, the electric push rod is started to drive the sealing plate to move horizontally, 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, and further improving the heat dissipation of the cabinet;

[0029] 5. In the present invention, for the intelligent dehumidifying and heat-dissipating high and low voltage switchgear cabinet, the monitored temperature value and humidity value are sent to the remote client through the signal transmitter, and the remote operation signal is received through the signal receiver, thus facilitating remote monitoring. When the temperature or humidity is too high, the controller controls the alarm to start, thereby realizing early warning. By pulling up the pull plate upward, and driving the two clamping plates to approach each other through the two pull ropes, the clamping plates are disengaged from the clamping grooves, releasing the fixation of the top plate. Then, by pulling up the handle, the baffle is removed, and thus the drying box can be taken out to facilitate the replacement of the desiccant;

[0030] 6. In the present invention, for the intelligent dehumidifying and heat-dissipating high and low voltage switchgear cabinet, the forced ventilation can be realized through the provided ventilation mechanism, the ventilation speed is adjusted according to the temperature, and the air flow direction inside the switchgear cabinet can be changed as needed to achieve uniform and controllable heat dissipation. While realizing dehumidification, heat dissipation is achieved through the provided condensation mechanism, and the condensed water is used for further heat dissipation work to improve the dehumidification and heat dissipation effect.

[0070] In this embodiment, during use, the cooperation of the cabinet door 101 and the sealing strip 102 can achieve the sealing of the switch cabinet. The ventilation frame 201 and the dust-proof net 211 facilitate the entry of natural wind into the cabinet body 1 to take away the internal heat and achieve heat dissipation. The temperature and humidity inside the cabinet body 1 are monitored by the temperature sensor and the humidity sensor 23. When the temperature sensor 11 detects an increase in temperature, the controller 10 controls the fan 210 to start, so that the outside air enters the cabinet body 1 through the ventilation frame 201 at the bottom of one side of the cabinet body 1, and then is discharged from the ventilation frame 201 at the top of the other side of the cabinet body 1. The heat is taken away when flowing through the inside of the cabinet body 1, so as to achieve the effect of forced ventilation and enhanced heat dissipation. And when the detected temperature is higher, the controller 10 controls the power of the fan 210 to increase, so as to increase the ventilation volume and improve the heat dissipation rate. During the ventilation process, the desiccant in the drying box 502 absorbs moisture, so as to dehumidify the solid.

[0071] The temperature difference between the two sides inside the cabinet body 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, so as to drive the connecting frame 206 to move up and down. The connecting frame 206 drives the rotation of a plurality of connecting arms 204 through the cooperation with the connecting column 205, and then drives the swing blade 202 to rotate through the rotating shaft 203, thereby changing the air flow direction and speed inside the cabinet body 1, and realizing efficient and uniform heat dissipation inside the cabinet body 1;

[0072] When the humidity sensor 23 detects that the humidity inside the cabinet body 1 is too high, the driving motor 610 and the condensation rod 604 are started. The driving motor 610 drives the crankshaft 609 to rotate. The driving shaft drives the piston plate 605 to move left and right reciprocally through the cooperation with the connecting plate 608, the moving plate 607 and the guide rail 606. During the process of the piston plate 605 moving to the left, the air inside the cabinet body 1 enters the condensation box 601 through the air inlet pipe 602 and the one-way valve 9 inside it. The condensation rod 604 cools the air inside it, so that the water vapor in the gas condenses and condenses on the surface of the condensation rod 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 outside the air inlet pipe 602, the air intake of the air inlet pipe 602 is blocked. When the piston plate 605 continues to move to the left, the air pressure inside the condensation box 601 is reduced. According to Dalton's law of partial pressures, reducing the pressure of the non-condensable gas can reduce the partial pressure of water vapor, thereby increasing the condensation rate of the moisture, making it easier for the water vapor to reach the saturation state and condense. The condensed water flows down along the condensation rod 604 and drips into the water collecting frame;

[0073] The crankshaft 609 drives the rotating plate 19 to rotate, and drives the two sleeve plates 17 to perform circular motion. Under the action of centrifugal force, the sleeve plates 17 move towards the side away from each other, and drive the connecting shaft 16 and the U-shaped frame 15 to move downward through the cooperation with the bent 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 hole, avoiding the linkage between the condensation box 601 and the water collection box 701 during the condensation process and affecting the negative pressure control of the condensation box 601. At the same time, the connecting plate 13 squeezes the piezoresistor 22 through the compression spring 21, thereby reducing the resistance value of the piezoresistor 22. Since it is connected in series with the condensation rod 604, the power of the condensation rod 604 increases. And the lower the humidity in the cabinet 1 monitored by the humidity sensor 23, the faster the output shaft speed of the drive motor 610 is controlled by the controller 10, so that the squeezing force on the piezoresistor 22 is greater, and thus the power of the condensation rod 604 is greater to improve the condensation effect, so as to achieve the dehumidification effect. After the dehumidification is completed, the controller 10 controls the drive motor 610 to stop running, and the connecting plate 13 resets under the action of the compression spring 21, so that the water outlet hole is opened, and the condensed water flows into the water collection box 701 for storage. When it is necessary to cool the inside of the cabinet 1 when the temperature is too high, the electric push rod 209 is started to drive the sealing plate to move horizontally, 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 to absorb heat, so as to cool the inclined frame 801 and the condensation frame, thereby further improving the heat dissipation of the cabinet 1;

[0074] The monitored temperature value and humidity value are sent to the remote client through the signal transmitter 402, and the remote operation signal is received through the signal receiver 401, so as to facilitate remote monitoring. When the temperature or humidity is too high, the controller 10 controls the alarm 403 to start, so as to achieve early warning. By pulling up the pull plate 509 and driving the two clamping plates 505 to approach each other through the two pull ropes 507, the clamping plates 505 are disengaged from the card slots, releasing the fixation of the top plate 501, and then pulling up the handle 510 to remove the baffle plate, so that the drying box 502 can be taken out to facilitate the replacement of the desiccant.

[0075] As Figure 15 shown, when the humidity in the cabinet 1 is too high, it means that the temperature of the outside air 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 are attached to each other, realizing the closure of the ventilation frame 201, so as to avoid being affected by the outside moisture, and then the condensation mechanism 6 is started separately to realize the initial and heat dissipation inside the cabinet 1.
