Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an online temperature and humidity monitoring device for high-voltage switchgear. Background Technology

[0002] Switchgear is a common type of power transmission and distribution equipment, playing a control or protection role in the power transmission and distribution process. Switchgear contains disconnecting switches, circuit breakers, and other related protective devices. The insulation capacity of the switchgear is a crucial factor in its safe and stable operation. When a power system fault occurs, its disconnecting switches can disconnect interconnected equipment.

[0003] Chinese Patent Publication No. CN113851942A discloses a moisture-proof switch cabinet. The switch cabinet includes a cabinet body, and the interior of the cabinet body is equipped with a temperature sensor, a humidity sensor, and a controller. The inner wall of the cabinet body is provided with a waterproof layer, which includes a first waterproof layer, a first adhesive layer, a second adhesive layer, and a second waterproof coating layer. The first adhesive layer, the first waterproof layer, the second adhesive layer, and the second waterproof layer are sequentially bonded to the inner wall of the cabinet body. An air supply device is provided at the bottom of the outer side of the cabinet body, and the air supply device is connected to a heating device at the bottom of the inner side of the cabinet body. An exhaust device is provided at the top of the other outer side of the cabinet body. The temperature sensor and the humidity sensor are respectively connected to the controller. The air supply device and the heating device are respectively connected to a PLC controller. The exhaust device is independently connected to the controller.

[0004] Although the aforementioned switch cabinet can ventilate and heat the cabinet through the heating device, the warm air blows from bottom to top of the cabinet, causing the heat to concentrate at the bottom of the cabinet and creating a significant temperature gradient from bottom to top inside the cabinet, resulting in poor moisture-proof performance. Utility Model Content

[0005] This invention provides an online temperature and humidity monitoring device for high-voltage switchgear, which can achieve relatively uniform temperature rise and extend the service life of electrical equipment inside the cabinet.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A high-voltage switchgear temperature and humidity online monitoring device includes a cabinet, a controller, a temperature sensor, and a humidity sensor installed inside the cabinet. The temperature sensor and the humidity sensor are both communicatively connected to the controller. The device also includes:

[0009] Two heaters are fixedly installed inside the two heating pipes, and both heaters are communicatively connected to the controller.

[0010] An exhaust assembly is fixedly installed in the cabinet and communicatively connected to the controller. The air inlet of the exhaust assembly extends into the cabinet, and the air outlet extends out of the cabinet.

[0011] The beneficial effects of this invention are as follows: During use, temperature and humidity sensors monitor the temperature and humidity inside the cabinet, respectively, and transmit the data to the controller. When the humidity is too high and the temperature is too low, the controller activates two heaters, blowing warm air into the cabinet through two heating pipes to raise the temperature of the environment inside the cabinet. During this process, because the outlets of the two heating pipes are open at opposite ends, the warm air blown out by the outlets of the two heating pipes blows against each other, forming a countercurrent vortex that quickly breaks down temperature stratification and achieves rapid and uniform heating inside the cabinet. When the temperature inside the cabinet is too high, the controller can shut down the two heaters and activate the exhaust system to expel the hot air from the cabinet, effectively preventing the aging of the equipment inside the cabinet due to excessive temperature and extending the service life of the electrical equipment inside the cabinet.

The air inlet ends of both vertical pipes are adapted to and rotatably connected to the corresponding holes, and both vertical pipes have ring blocks that are adapted to and rotatably connected to the corresponding annular grooves fixedly connected to their sidewalls.

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] Example 1

[0035] like Figures 1-5 A high-voltage switchgear temperature and humidity online monitoring device includes a cabinet 1, a controller 2, a temperature sensor 21, and a humidity sensor 22 installed inside the cabinet 1. Both the temperature sensor 21 and the humidity sensor 22 are communicatively connected to the controller 2. The device also includes:

[0036] Two heating tubes 3 are fixedly installed at the bottom and top of the cabinet 1 respectively. The air inlet of the two heating tubes 3 extends out of the cabinet 1 and the air outlet extends into the cabinet 1. The air outlets of the two heating tubes 3 are open at opposite ends.

[0037] Two heaters 4 are fixedly installed inside two heating pipes 3, and both heaters 4 are communicatively connected to the controller 2.

[0038] The exhaust assembly 5 is fixedly installed in the cabinet 1 and communicates with the controller 2. The air inlet of the exhaust assembly 5 extends into the cabinet 1, and the air outlet extends out of the cabinet 1.

[0039] The beneficial effects of this embodiment are as follows: During use, the temperature and humidity inside the cabinet 1 are monitored by the temperature sensor 21 and the humidity sensor 22, respectively, and the data is transmitted to the controller 2. When the humidity is too high and the temperature is low, the controller 2 controls the two heaters 4 to start, blowing warm air into the cabinet 1 through the two heating pipes 3, thereby raising the temperature of the environment inside the cabinet 1. During this process, since the air outlets of the two heating pipes 3 are open at opposite ends, the warm air blown out by the air outlets of the two heating pipes 3 blows against each other, forming a countercurrent vortex, which quickly breaks up the temperature stratification and achieves rapid and uniform heating inside the cabinet 1. When the temperature inside the cabinet 1 is too high, the controller 2 can control the two heaters 4 to turn off and control the exhaust assembly 5 to start, thereby expelling the high-temperature air inside the cabinet 1 through the exhaust assembly 5, effectively preventing the aging of the equipment inside the cabinet due to excessive temperature inside the cabinet 1, and extending the service life of the electrical equipment inside the cabinet.

[0040] Example 2

[0041] like Figures 1-3 Based on Example 1, each of the two heating pipes 3 includes an air inlet pipe 31, a connecting pipe 32, and an air outlet pipe 33. The two air inlet pipes 31 are fixedly installed at the bottom and top of the cabinet 1, respectively. The air inlet ends of the two air inlet pipes 31 extend outside the cabinet 1, and the air outlet ends extend into the cabinet 1. The air inlet ends of the two connecting pipes 32 are respectively connected to the air outlet ends of the two air inlet pipes 31, and the two air outlet pipes 33 extend vertically. The air inlet ends of the two air outlet pipes 33 are respectively connected to the air outlet ends of the two connecting pipes 32. The air outlet ends of the two air outlet pipes 33 are open at opposite ends. The two heaters 4 are fixedly installed inside the two air inlet pipes 31.

[0042] The beneficial effect of adopting the preferred solution in the above embodiments is that when the warm air blown into the cabinet 1 by the heater 4 to raise the temperature of the environment inside the cabinet 1, the air outside the cabinet 1 enters the transfer pipe 32 through the air inlet pipe 31, then enters the air outlet pipe 33 and is discharged from the air outlet pipe 33. The two air outlet pipes 33, which are opposite each other, guide the warm air, so that the warm air blows against each other, forming a countercurrent vortex, which quickly breaks the temperature stratification and achieves rapid and uniform heating inside the cabinet 1.

[0043] Example 3

[0044] like Figures 1-3Based on embodiments 1 and 2, both adapter pipes 32 include a vertical pipe 321 and an inclined pipe 322. The air inlet ends of the two vertical pipes 321 are respectively connected to the air outlet ends of the two air inlet pipes 31, and the air inlet ends of the two inclined pipes 322 are respectively connected to the air outlet ends of the corresponding vertical pipes 321. The air outlet ends of the two inclined pipes 322 extend upward at an angle, and the air inlet ends of the two air outlet pipes 33 are respectively connected to the air outlet ends of the two inclined pipes 322.

[0045] The beneficial effect of adopting the preferred solution in the above embodiments is that the warm air squeezed by the air inlet pipe 31 can be smoothly discharged into the air outlet pipe 33 through the connection of the vertical pipe 321 and the inclined pipe 322, thereby achieving the heating of the cabinet 1.

[0046] Example 4

[0047] like Figures 1-3 Based on embodiments 1-3, both adapter pipes 32 are rotatably connected to the air outlet of the corresponding air inlet pipe 31 with their rotation axis as the central axis of the vertical pipe 321; both heating pipes 3 also include two drive components 34 fixedly connected in the cabinet 1, both drive components 34 are communicatively connected to the controller 2, and the drive ends of both drive components 34 are drively connected to the corresponding adapter pipe 32.

[0048] The beneficial effect of adopting the preferred solution in the above embodiments is that when warm air is blown into the cabinet 1 by the heater 4 to raise the temperature of the environment inside the cabinet 1, the drive component 34 can be started by the controller 2, so that the two adapter pipes 32 rotate, and the two air outlet pipes 33 rotate circumferentially about the rotation axis of the air inlet end of the adapter pipe 32, so as to realize the circumferential blowing of warm air, further improve the uniformity of the blowing, and avoid the occurrence of temperature gradient.

[0049] Example 5

[0050] like Figures 1-3 Based on Examples 1-4, multiple fine holes 3221 are opened through the two inclined tubes 322 on the opposite side.

[0051] The beneficial effect of adopting the preferred solution in the above embodiments is that when the warm air in the vertical pipe 321 is transmitted to the air outlet pipe 33 through the inclined pipe 322, the warm air can be discharged through each fine hole 3221, and together with the rotating air outlet pipe 33, a warm air output in the circumferential surface is formed, thereby improving the uniformity of heating.

[0052] Example 6

[0053] like Figures 1-3Based on embodiments 1-5, both drive components 34 include a bracket 341 fixedly connected to the cabinet 1, a motor 342 fixedly installed on the bracket 341, a gear 343 rotatably connected to the bracket 341 and coaxially fixedly connected to the motor 342, and a gear ring 344 meshing with the gear 343. The inner sides of the two gear rings 344 are respectively fixedly connected to the outer sides of the two vertical pipes 321, and both motors 342 are communicatively connected to the controller 2.

[0054] The beneficial effect of adopting the preferred solution in the above embodiments is that the controller 2 controls the motor 342 to start, drives the gear 343 to rotate, and drives the gear 343 to rotate, so that the vertical pipe 321 rotates with its central axis as the axis of rotation, so that the transfer pipe 32 and the air outlet pipe 33 can achieve axial blowing operation, and achieve a uniform rise in the temperature of the cabinet 1.

[0055] Example 7

[0056] like Figures 1-3 Based on embodiments 1-6, the side walls of both air inlet pipes 31 are connected to each other with insertion holes, and the side walls of both insertion holes are provided with annular grooves 311. The air inlet ends of both vertical pipes 321 are adapted to and rotatably connected to the corresponding insertion holes, and the side walls of both vertical pipes 321 are fixedly connected with ring blocks 3211 that are adapted to and rotatably connected to the corresponding annular grooves 311.

[0057] The beneficial effect of adopting the preferred solution in the above embodiments is that the corresponding ring block 3211 can be rotated and installed through the annular slot 311, thereby achieving stable rotational installation of the corresponding vertical pipe 321.

[0058] Based on the above embodiment, each of the two air inlet pipes 31 has a rotating groove 312 on its sidewall. Multiple support rods 3441 are fixedly connected to the sidewall of the toothed ring 344. The ends of each support rod 3441 are adapted to and rotatably connected to the rotating groove 312 to achieve stable installation of the toothed ring 344. Furthermore, the cross-section of the rotating groove 312 is stepped or dovetail-shaped to prevent the support rods 3441 from rotating, thereby further improving the stable rotational installation of the vertical pipe 321.

[0059] Example 8

[0060] like Figures 1-3 Based on embodiments 1-7, each of the two heating tubes 3 further includes two arc-shaped covers 35. The two arc-shaped covers 35 are respectively closed and fixedly connected to the air outlet ends of the two air outlet tubes 33, and the two arc-shaped covers 35 are provided with multiple air outlet holes 351.

[0061] The beneficial effect of adopting the preferred solution in the above embodiments is that when warm air is discharged from the air outlet 33, it is discharged from multiple air outlets 351 at the same time. Since the arc-shaped cover 35 has an arc-shaped structure, the air outlets 351 are oriented differently, which can expand the air outlet area of ​​the warm air, improve the uniformity of the warm air blowing, and achieve uniform heating. In addition, the arc-shaped cover 35 can reduce the possibility of debris entering the air outlet 33 from the air outlet end of the air outlet 33.

[0062] Based on the above embodiment, the diameter of the air outlet 351 is larger than the diameter of the fine hole 3221 to ensure the air volume blown out from the air outlet 351.

[0063] Example 9

[0064] like Figure 1 and Figure 4 Based on embodiments 1-8, each of the two heating pipes 3 further includes two first filters 36, which are fixedly installed in the two air inlet pipes 31 respectively, and the two first filters 36 are close to the air inlet end of the corresponding air inlet pipe 31 relative to the corresponding heater 4.

[0065] The advantage of adopting the preferred solution in the above embodiments is that it can block debris entering the air inlet duct 31 through the first filter screen 36.

[0066] Example 10

[0067] like Figure 1 and Figure 5 Based on embodiments 1-9, the exhaust assembly 5 includes an exhaust pipe 51 fixedly connected to the cabinet 1, an exhaust fan 52 fixedly installed in the exhaust pipe 51, and a second filter 53 fixedly installed in the exhaust pipe 51. The air inlet end of the exhaust pipe 51 extends into the cabinet 1, and its air outlet end extends out of the cabinet 1. The exhaust fan 52 is communicatively connected to the controller 2, and the exhaust fan 52 is closer to the air inlet end of the exhaust pipe 51 than the second filter 53.

[0068] The beneficial effect of adopting the preferred solution in the above embodiments is that when the temperature inside the cabinet 1 is too high, the controller 2 controls the exhaust fan 52 to start and discharge the high-temperature gas inside the cabinet 1. The second filter 53 can prevent external debris from entering the cabinet 1 through the exhaust pipe 51.
