Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear technology, and in particular to a mobile monitoring type high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is a crucial piece of equipment in power systems, primarily used for power distribution and control to ensure the safe and reliable transmission of electricity from power plants or substations to end users. With the continuous increase in electricity demand and the growing complexity of power systems, the stability and safety of high-voltage switchgear have become paramount. High-voltage switchgear typically contains key components such as circuit breakers, disconnectors, busbars, current transformers, and voltage transformers. These components generate significant heat during operation and are also subject to specific humidity requirements. To ensure the stable operation of high-voltage switchgear, real-time monitoring and control of the internal temperature and humidity are essential.

[0003] Existing high-voltage switchgear uses sensing components to monitor the temperature and humidity inside the cabinet in real time. However, the sensing components are fixed in position inside the cabinet, the monitored area is small, and there are many blind spots, which is not conducive to the safe operation of high-voltage switchgear. Summary of the Invention

[0004] To address the shortcomings of existing high-voltage switchgear where the sensor components are fixed in position and have many blind spots, this invention proposes a mobile monitoring high-voltage switchgear. The sensor components move within the cabinet to monitor, reducing blind spots and improving the safety of the high-voltage switchgear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mobile monitoring high-voltage switchgear includes a cabinet, a power distribution mechanism, a rail, a sliding mounting base, a sensing component, and a drive mechanism. The power distribution mechanism is installed in the cabinet, the rail is fixedly connected in the cabinet, the sliding mounting base is slidably connected to the rail and driven by the drive mechanism, and the sensing component is installed on the sliding mounting base for monitoring the temperature and humidity inside the cabinet. The high-voltage distribution cabinet also includes an air conditioner, a dehumidifier, and a controller. The controller controls the operation of the air conditioner and dehumidifier based on the monitoring data of the sensor components to control the temperature and humidity inside the cabinet.

[0006] Furthermore, the drive mechanism includes a bracket, a push rod, and a motor. The bracket is vertically fixed in the cabinet, and the track extends in the front and back direction and is fixedly connected to the upper end of the bracket. A moving rod is fixedly connected to the side of the sliding mounting base. The lower end of the push rod is rotatably connected to the bracket and driven by the motor. The push rod has an elongated hole along its length, and the moving rod is slidably connected in the elongated hole.

[0007] Furthermore, the drive mechanism also includes a rotating rod, with the motor fixedly connected to the bracket and connected to one end of the rotating rod. The other end of the rotating rod is fixedly connected to a lever, which is slidably connected in the elongated hole.

[0008] Furthermore, the sliding mounting base includes a slider, a connecting mechanism, a locking mechanism, and a mounting plate. The slider is slidably connected to the track, the mounting plate extends vertically, the upper end of the mounting plate is detachably connected to the slider through the connecting mechanism, and the sensing component is locked onto the mounting plate through the locking mechanism.

[0009] Furthermore, a mounting groove extending in the front-to-back direction is provided on the lower side of the slider, and the mounting groove extends through to the rear side of the slider. The upper end of the mounting plate is adapted to the mounting groove and is slidably connected in the mounting groove. The connecting mechanism includes a spring, a pin, and a connecting plate. The pin is vertically installed on the rear side of the slider and can move up and down. The spring is installed between the pin and the slider. The connecting plate is fixedly connected to the upper rear side of the mounting plate and is provided with a socket. The lower end of the pin is inserted into the socket.

[0010] Furthermore, the locking mechanism includes a housing, a pressure plate, a threaded sleeve, and a screw. The mounting plate is provided with mounting holes that fit the housing. The housing is fixedly connected in the mounting holes. The housing is open on the side facing the power distribution mechanism. The threaded sleeve passes through the upper side of the housing and is fixedly connected to the housing. The screw is threadedly connected to the threaded sleeve. The lower end of the screw is located in the housing and is connected to the pressure plate. The sensing component is located in the housing and is pressed into the housing by the pressure plate.

[0011] Furthermore, there are two tracks, symmetrically arranged on the left and right sides of the power distribution mechanism. Each track is slidably connected to a sliding mounting seat, and the sliding mounting seats are fixedly connected to each other by a crossbeam.

[0012] Furthermore, the inner side of the cabinet extends forward and backward and is fixedly connected to a connecting groove. A connecting strip is slidably connected in the connecting groove. A mounting frame is fixedly connected to the lower side of the connecting strip via a connecting rod. The mounting frame is located near the middle of the cabinet, and the dehumidifier is installed in the mounting frame.

[0013] Through the above improvements, the high-voltage distribution cabinet of the present invention has the following beneficial effects: 1. In this invention, the sensing components move within the cabinet to monitor temperature and humidity, which can cover more monitoring areas, reduce monitoring blind spots, and improve the safety of the high-voltage distribution cabinet; 2. In this invention, the sensing components are easy to disassemble and assemble, and easy to repair and replace without causing power outages or affecting the user's power supply. 3. In this invention, sensing components are symmetrically arranged on the left and right sides of the power distribution mechanism to further reduce monitoring blind spots and improve the safety of the high-voltage power distribution cabinet; 4. In this invention, when the motor rotates in one direction via the rotating rod, the sliding mounting base can be driven to reciprocate through the push rod, making the motor's movement simpler and the sliding mounting base's movement more stable.

[0018] Figure 5 for Figure 4 Enlarged view of point A. Detailed Implementation

[0019] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] like Figures 1 to 5 The present invention provides a mobile monitoring high-voltage distribution cabinet, wherein the sensing component 7 moves within the cabinet 3 to monitor temperature and humidity, thereby covering more monitoring areas, reducing monitoring blind spots, and thus improving the safety of the high-voltage distribution cabinet. Figure 1The front, back, left, right, top, and bottom directions of the high-voltage distribution cabinet are defined in this document to describe the technical solution. Specifically, the high-voltage distribution cabinet in this embodiment includes a cabinet body 3, a distribution motor assembly 4, a rail 5, a sliding mounting base 6, a sensing component 7, and a drive mechanism. The cabinet body 3 is a hollow cuboid structure placed on the ground. The distribution motor assembly 4 is installed in the cabinet body 3 to perform the power distribution function of the high-voltage distribution cabinet. Since the distribution motor assembly 4 is not the focus of this application, it will not be described in detail. The rail 5 extends in the front-back direction and is fixedly connected in the cabinet body 3, near the upper end of the cabinet body 3. The sliding mounting base 6 is slidably connected to the rail 5 and driven by the drive mechanism. The front end of the rail 5 is close to the cabinet body. 3. The rear end of the track 5 is close to the rear side of the cabinet 3, which expands the movement range of the sliding mounting base 6. The drive mechanism can be a linear motor 12, a screw and nut structure, or other structures, which are not limited for the time being. The upper end of the sliding mounting base 6 is slidably connected to the track 5 and extends vertically. The sensing component 7 integrates a temperature sensor and a humidity sensor. The temperature sensor is used to monitor the temperature inside the cabinet 3, and the humidity sensor is used to monitor the humidity inside the cabinet 3. The upper end of the sliding mounting base 6 is close to the upper end of the cabinet 3, and the lower end of the sliding mounting base 6 is close to the lower end of the cabinet 3. Multiple sensing components 7 are provided and are evenly arranged on the sliding mounting base 6 from top to bottom to monitor the temperature and humidity at different heights. The high-voltage distribution cabinet also includes an air conditioner 8, a dehumidifier 9, and a controller (not shown in the figure). The controller controls the operation of the air conditioner 8 and the dehumidifier 9 based on the monitoring data of the sensor component 7, so as to control the temperature and humidity inside the cabinet 3.

[0021] The working principle of the high-voltage distribution cabinet in this embodiment is as follows: the distribution motor 12 mechanism 4 is connected to an external high-voltage line to perform power distribution tasks. The distribution motor 12 mechanism 4 generates a large amount of heat during operation. The sensing component 7 monitors the temperature and humidity inside the cabinet 3 in real time. The drive mechanism drives the sliding mounting base 6 to reciprocate back and forth on the track 5. The sensing component 7 reciprocates with the sliding mounting base 6 to monitor the temperature and humidity at different locations along its movement path. Compared to traditional fixed-position monitoring, this provides a wider monitoring range and reduces blind spots. The sensing component 7 monitors temperature and humidity in real time, and since the temperature and humidity may vary at different locations, the controller monitors these parameters in real time. The system receives monitoring data from sensor component 7 and calculates the highest temperature and maximum humidity of each sensor component 7 during a single reciprocating motion. When the highest temperature of one sensor component 7 exceeds a first threshold (here, the first threshold is 50 degrees Celsius), the air conditioner 8 increases its power to improve heat dissipation efficiency. When the highest temperature of each sensor component 7 during a single reciprocating motion is below a second threshold (here, the second threshold is 40 degrees Celsius), the air conditioner 8 reduces its power to save energy. Ultimately, the highest temperature of each sensor component 7 during a single reciprocating motion within the cabinet 3 fluctuates between 40 and 50 degrees Celsius, preventing excessively high temperatures within the cabinet 3 and ensuring the safe operation of the high-voltage distribution cabinet. Similarly, when the highest humidity of one of the sensing components 7 is higher than the third threshold (where humidity refers to relative humidity, and the third threshold is 70%), the dehumidifier 9 increases its power to improve dehumidification efficiency, and the humidity in the cabinet 3 decreases. When the highest humidity of each sensing component 7 during a single reciprocating motion is lower than the fourth threshold (where the fourth threshold is 40%), the dehumidifier 9 reduces its power to save energy. Ultimately, the highest humidity of each sensing component 7 during a single reciprocating motion within the cabinet 3 fluctuates between 40% and 70%, ensuring that the highest humidity of each sensing component 7 along its movement path is between 40% and 70%, thus guaranteeing the safe operation of the high-voltage distribution cabinet.

[0022] In one embodiment, such as Figure 2 The drive mechanism includes a bracket 10, a push rod 11, and a motor 12. The bracket 10 is vertically fixed in the cabinet 3. The track 5 extends forward and backward and is fixedly connected to the upper end of the bracket 10. A moving rod 13, which is cylindrical, is fixedly connected to the side of the sliding mounting base 6. The lower end of the push rod 11 is rotatably connected to the bracket 10 and is driven by the motor 12. A bearing is installed between the lower end of the push rod 11 and the bracket 10 to improve the rotational stability of the push rod 11. The push rod 11 has an elongated hole 14 along its length, and the moving rod 13 is slidably connected in the elongated hole 14. The width of the elongated hole 14 is adapted to the outer diameter of the moving rod 13 to improve the stability of the movement of the sliding mounting base 6. With the above configuration, when the motor 12 drives the push rod 11 to rotate, when the push rod 11 rotates forward, the push rod 11 pushes the sliding mounting base 6 forward along the track 5 through the moving rod 13. When the push rod 11 rotates backward, the push rod 11 pushes the sliding mounting base 6 backward along the track 5 through the moving rod 13.

[0023] In one embodiment, such as Figure 2 The drive mechanism also includes a rotating rod 15. The motor 12 is fixedly connected to the bracket 10 and connected to one end of the rotating rod 15. The other end of the rotating rod 15 is fixedly connected to a lever 16. The lever 16 is slidably connected in the elongated hole 14. The elongated hole 14 extends to the lower end of the push rod 11, so that the motor 12 can drive the rotating rod 15 to rotate 360 ​​degrees. Under the unidirectional rotation drive of the motor 12, the rotating rod 15, similar to a cam mechanism, drives the push rod 11 to swing back and forth.

[0024] In one embodiment, such as Figure 4 and Figure 5The sliding mounting base 6 includes a slider 17, a connecting mechanism, a locking mechanism, and a mounting plate 18. The slider 17 is slidably connected to the track 5, and the mounting plate 18 extends vertically to support multiple vertically arranged sensing components 7. The upper end of the mounting plate 18 is detachably connected to the slider 17 through the connecting mechanism, and the sensing components 7 are locked onto the mounting plate 18 through the locking mechanism. This configuration facilitates the maintenance and replacement of the sensing components 7. When maintenance or replacement of the sensing components 7 is required, the interface on the sensing component 7 is disconnected, the mounting plate 18 is removed from the slider 17, and the entire mounting plate 18 is taken out of the cabinet 3 to maintain and replace the sensing components 7 on the mounting plate 18. After the operation is completed, the mounting plate 18 is put back into the cabinet 3 and installed on the slider 17. The entire process does not require shutting down the distribution motor 12 mechanism 4, does not affect the operation of the distribution motor 12 mechanism 4, and therefore does not affect the user's power supply or cause a power outage.

[0025] In one embodiment, such as Figure 4 and Figure 5 The slider 17 has a mounting groove 19 extending forward and backward on its lower side, extending to the rear side of the slider 17. This allows the upper end of the mounting plate 18 to slide forward into the mounting groove 19. The upper end of the mounting plate 18 is adapted to the mounting groove 19 and slidably connected within it. The mounting groove 19 has an inverted T-shaped cross-section, ensuring that the upper end of the mounting plate 18 can only move forward and backward within the groove, preventing it from moving up and down. This allows the mounting plate 18 to be stably suspended below the slider 17. The connecting mechanism includes a spring 20, a pin 21, and a connecting plate 22. The pin 21 is vertically mounted on the rear side of the slider 17 and can move up and down. The spring 20 is installed between the pin 21 and the slider 17. The connecting plate 22 is fixedly connected to the rear side of the upper end of the mounting plate 18 and has a socket 23. The lower end of the pin 21 is inserted into the socket 23 to prevent the mounting plate 18 from sliding down. The spring 20 moves back and forth to prevent the upper end of the mounting plate 18 from disengaging from the slider 17. At this time, the spring 20 is in a free state, preventing the pin 21 from easily moving up and down to unlock. When the mounting plate 18 needs to be removed, manually push the pin 21 upwards. The spring 20 deforms, and the lower end of the pin 21 is pulled out from the insertion hole 23 on the connecting plate 22. The mounting plate 18 can then move backwards from the mounting groove 19 of the slider 17, thus removing the mounting plate 18. After releasing the pin 21, the spring 20 rebounds, and the pin 21 moves downwards to its initial position. When the mounting plate 18 needs to be reinstalled, manually push the pin 21 upwards, then slide the upper end of the mounting plate 18 into the mounting groove 19 of the slider 17. After releasing the pin 21, the pin 21 rebounds downwards and is reinserted into the insertion hole 23 of the connecting plate 22, completing the installation of the mounting plate 18.

[0026] In one embodiment, such as Figure 4 and Figure 5The locking mechanism includes a housing 24, a pressure plate 25, a threaded sleeve 26, and a screw 27. The mounting plate 18 has mounting holes 28 that fit the housing 24. The housing 24 is fixedly connected to the mounting holes 28. The housing 24 is open on the side facing the motor assembly 12 4 to facilitate monitoring of the temperature and humidity on that side. The threaded sleeve 26 passes through the upper side of the housing 24 and is fixedly connected to it. The screw 27 is threadedly connected to the threaded sleeve 26. The lower end of the screw 27 is located in the housing 24 and rotates with the pressure plate 25. The sensor assembly 7 is housed in the housing 24 and pressed into the housing 24 by the pressure plate 25. When the screw 27 is manually rotated, the screw 27 rotates relative to the threaded sleeve 26. The screw 27 drives the pressure plate 25 to move upward or downward. When the pressure plate 25 moves upward, it releases the sensor assembly 7, allowing it to be removed from the housing 24 for easy replacement and maintenance. When the pressure plate 25 moves downward, it presses the sensor assembly 7 into the housing 24, preventing it from falling out of the housing 24.

[0027] In one embodiment, such as Figure 1 There are two tracks 5, which are symmetrically arranged on the left and right sides of the distribution motor 12 structure 4. Each track 5 is slidably connected to a sliding mounting seat 6. A sensor component 7 can be installed on each sliding mounting seat 6 to monitor the temperature and humidity on the left and right sides of the distribution motor 12 structure 4. The sliding mounting seats 6 are fixedly connected to each other by a crossbeam 36, so that the sliding mounting seats 6 on the left and right sides can share a drive mechanism to move synchronously.

[0028] In one embodiment, a connecting groove 29 is fixedly connected to the inner side of the cabinet 3 extending forward and backward. A connecting strip 30 is slidably connected in the connecting groove 29. The connecting strip 30 can slide forward into the connecting groove 29 to complete the installation of the connecting strip 30. The connecting strip 30 can be pulled out from the connecting groove 29 to complete the disassembly of the connecting strip 30. A mounting frame 32 is fixedly connected to the lower side of the connecting strip 30 through a connecting rod 31. The mounting frame 32 is close to the middle of the cabinet 3. The dehumidifier 9 is installed in the mounting frame 32 so that the dehumidifier 9 can dehumidify efficiently.
