Description

Technical Field

[0001] This invention relates to the field of terminal boxes, and in particular to an outdoor terminal box and an anti-condensation system. Background Technology

[0002] Outdoor terminal boxes, as key installation carriers for secondary equipment in power systems, are widely used in outdoor scenarios such as substations and transmission lines. Their operational stability directly affects the safe and reliable power supply of the power grid. However, Guizhou, located in southwestern China, is situated in the eastern part of the Yunnan-Guizhou Plateau. Its terrain is mainly plateau and mountainous, with an average altitude of about 1,100 meters. The climate is a subtropical humid monsoon climate with abundant rainfall, with rain and heat occurring simultaneously. The annual precipitation is generally between 1,000 and 1,400 millimeters. This geographical location and climate mean that electrical equipment in Guizhou is in a humid environment all year round, resulting in severe insulation degradation. This has a significant impact on the operating electrical equipment, especially the secondary equipment inside the outdoor terminal boxes. Due to the low voltage and small spacing, the insulation degradation can easily cause short circuits and grounding in the secondary equipment, leading to failure to operate, malfunction, or burnout. This can cause grid instability and seriously affect the reliability of power supply. Furthermore, when performing wiring operations, workers need to lie on the bottom of the outdoor terminal box, look up, and slowly find the holes to thread the wires, which is difficult and inefficient.

[0023] Specifically, the heat-insulating metal plate 141 is inclined and double-layered, with a third insulation cotton a filling the middle. There are two sealing gaskets 143 and two mounting plates 142, and the two sealing gaskets 143 and two mounting plates 142 are symmetrically arranged. The sealing gaskets 143 and mounting plates 142 are fixedly connected to the heat-insulating metal plate 141. The sealing gaskets 143 improve the sealing performance of the connection between the heat-insulating metal plate 141 and the housing 11. The support base 144 is fixedly connected to the heat-insulating metal plate 141, and the rainproof base 146 is fixedly connected to the support base 144. The rainproof base 146 serves to protect against rain.

[0024] The wire threading part 2 includes a wire threading hole 21 provided on the base 15. The base 15 is provided with a wire threading groove 22. Two channel steels 23 are provided in the wire threading groove 22. Two wire threading metal plates 24 are provided between the two channel steels 23.

[0025] Specifically, multiple wiring holes 21 are provided, arranged in two rows at equal intervals. The wiring holes 21 are arc-shaped to allow workers to perform wiring operations while crouching. The fan 16 corresponds to the wiring trough 22, which is connected to the interior of the enclosure 11. Two channel steels 23 are symmetrically arranged in a U-shape, serving as load-bearing elements. The spacing between the two wiring metal plates 24 is 15cm to reduce the possibility of moisture from the cable trench and ground entering the enclosure 11. The wiring metal plates 24 are double-layered, with a fourth insulation cotton b filling the middle. The fixing slots 25 are symmetrically arranged, with two longitudinal fixing slots 25 corresponding to each other. The two fixing slots 25 correspond to the positions of the two rows of wire holes 21. The fixing slots 25 are provided with end A and end B with a surface area larger than end A, so that the wire threading piece 26 and the extrusion piece 28 can be placed in the fixing slots 25 to prevent them from falling out of the fixing slots 25. The extrusion plate 27 is provided with end C and end D with a surface area larger than end C. The side wall of the extrusion plate 27 is provided with a connecting groove c, so that the extrusion plate 27 can be placed into the fixing slots 25 and placed on the wire threading metal plate 24 to prevent the extrusion plate 27 from falling out of the fixing slots 25.

[0026] The cable threading component 26 includes a front half 261 and a rear half 262. The inner walls of the front half 261 and the rear half 262 are both bonded with silicone soft rubber pads 263. A block 264 is provided between the two silicone soft rubber pads 263. The silicone soft rubber pads 263 are arranged in multiple layers.

[0027] Specifically, the front half 261 and the rear half 262 are both made of elastic silicone. The silicone soft pad 263 is C-shaped. Through multiple layers of silicone soft pads 263, the number of layers can be removed according to the cable diameter to adapt to different specifications of cables. The plug 264 is cylindrical and made of silicone. The plug 264 is detachably bonded to the innermost silicone soft pad 263 to seal when not threading cables. As shown in the figure, the left threading piece 26 is in a sealed state, and the right threading piece 26 is in an unsealed state. The left side is reserved. When threading cables, the plug 264 can be removed and the number of silicone soft pads 263 layers can be adjusted according to the cable size. This can effectively prevent small animals and water vapor from entering the threading groove 22 and the box 11 through the round holes formed by the silicone soft pads 263 when in the reserved state. It should be noted that the upper and lower parts of the inner wall of the wire hole 21 are provided with plugs d, and the plugs d are composed of two multi-layer silicone soft rubber pads 263 and plugs 264, which not only improves the sealing effect, but also does not affect the convenience of the wire threading operation, thus achieving a balance between sealing protection and construction convenience.

[0028] The extrusion component 28 includes two extrusion blocks 281 and two bidirectional bolts 282 disposed in the fixing groove 25. The side walls of the two extrusion blocks 281 are provided with two U-shaped grooves 283. The two transverse U-shaped grooves 283 are provided with an elastic band 284. The side walls of the two extrusion blocks 281 are provided with a limiting plate 285. The outer surfaces of the two bidirectional bolts 282 are provided with two moving blocks 286. The bottom of the two bidirectional bolts 282 is provided with a limiting block 287. The two moving blocks 286 and the two extrusion blocks 281 are provided with inclined surfaces 288.

[0029] Specifically, the two compression blocks 281 and the two bidirectional bolts 282 are symmetrically arranged, and the elastic band 284 is arranged in a U-shape. The elastic band 284 facilitates the reset of the two compression blocks 281. There are two limiting plates 285, and the two limiting plates 285 and the two U-shaped grooves 283 are symmetrically arranged. The limiting plates 285 can limit the elastic band 284 and prevent it from disengaging from the U-shaped grooves 283. When the bidirectional bolts 282 rotate, the two moving blocks 286 can move away from each other or move closer together. Through the inclined plane 288, when the two moving blocks 286 move closer together, they will squeeze the two compression blocks 281. Under the action of the inclined plane 288, the two compression blocks 281 will move away from each other. When the two moving blocks 286 move away from each other, the two compression blocks 281 lose the squeezing force and gradually reset under the action of the elastic band 284.

[0030] The moisture-proof and dehumidifying unit 3 includes a heater 31 mounted on one of the wire-threading metal plates 24. The side wall of the cabinet door 12 is equipped with a temperature and humidity sensor 32 and a PLC control panel 33. The side wall of the cabinet door 12 is equipped with a camera 34. The side wall of the heat-insulating metal plate 141 is equipped with a small air conditioner 35. The small air conditioner 35 is equipped with a drain pipe 36. The side wall of the cabinet body 11 is equipped with a water collection tank 37. The side wall of the water collection tank 37 is equipped with a water outlet pipe 38. The water outlet pipe 38 is connected to the water collection tank 37.

[0031] Specifically, the heater 31 is fixedly installed on the upper wire-threading metal plate 24. The temperature and humidity sensor, PLC control panel 33, and camera 34 are all fixedly installed on one of the cabinet doors 12. The camera 34 is a visible light and infrared light integrated camera. The small air conditioner 35 dehumidifies the inside of the cabinet 11. In summer, the small air conditioner 35 cools the inside of the cabinet 11. The drain pipe 36 is connected to the small air conditioner 35, so that during dehumidification, the moisture is discharged into the water collection tank 37 through the drain pipe 36 and discharged through the water outlet pipe 38. The water collection tank 37 is fixedly connected to the cabinet 11. The bottom wall of the water collection tank 37 is inclined to prevent water from accumulating in the water collection tank 37.

[0032] In use, the terminal block is fixedly installed on the support rod 13, and the equipment is installed inside the housing 11. The extrusion piece 28 and extrusion plate 27 are first removed from the fixing groove 25. The plug 264 in the right-side cable threading piece 26 is removed. The number of layers is disassembled according to the cable diameter. Then, the worker squats in the cable trench and inserts the cable through the threading hole 21 into the threading groove 22 and then into the fixing groove 25, so that multiple cables are respectively located between the corresponding front half 261 and rear half 262. Afterwards, the worker can stand in front of the housing 11 to perform wiring operations, eliminating the need for the worker to crawl directly under the device, lie down, and slowly search for the holes to thread the cable. This reduces the difficulty of wiring, decreases the workload, and improves wiring efficiency. Finally, the two silicone soft pads 263 are in contact. Adhesive is applied to the corresponding silicone rubber pads 263 to make them detachably bonded, thereby confining the cable within the corresponding silicone rubber pads 263. Then, multiple threading parts 26 are brought into contact, and the extrusion plate 27 and extrusion parts 28 are placed into the fixing groove 25. At this time, the fixing groove 25 is filled without gaps. By rotating the bidirectional bolt 282, the two moving blocks 286 are brought closer together under the constraint of the fixing groove 25. Under the action of the inclined plane 288, the two extrusion blocks 281 move away from each other. At this time, since the fixing groove 25 is fixed, the two extrusion blocks 281 can move towards the extrusion plate 27 by moving away from each other, so that the multiple threading parts 26 are squeezed and connected tightly, and the silicone rubber pads 263 are connected tightly to the cable, ensuring that the sealing is not affected after threading. Two metal plates 24 reduce the possibility of moisture from the cable trench and ground entering the enclosure 11. A fan 16 exhausts rising moisture and rainwater from the cable tray 22, preventing these from entering the enclosure 11. A heater 31 heats the enclosure 11, causing moisture to rise. A small air conditioner 35 then drains the moisture through a drain pipe 36 into a collection tank 37, and finally discharges it through a drain pipe 38, preventing condensation. The first insulation cotton 18 of the hot metal wire heats the wall of the box 11 to prevent moisture from condensing on the wall of the box 11 due to the temperature difference between the inside and outside of the box 11. This reduces the possibility of condensation from the source and ensures a stable and reliable anti-condensation effect. Together with the heat insulation metal plate 141, the third insulation cotton a in the support base 144 and the fourth insulation cotton b in the wire-threading metal plate 24, it achieves heat insulation and heat preservation, ensures the internal temperature of the box 11, improves the anti-condensation effect, avoids the equipment inside the box 11 being in a humid environment, and ensures the reliability of power supply. The temperature and humidity sensor 32 collects the temperature and humidity data inside the cabinet 11 in real time and transmits it to the PLC control panel. The PLC control panel automatically controls the heater 31, small air conditioner 35, heating wire and fan 16 to start and stop according to the preset threshold, so as to realize intelligent anti-condensation regulation.

[0033] Example 3 Reference Figures 5 to 9 The difference between this embodiment and the second embodiment is that the base 15 is U-shaped.

[0034] Specifically, the U-shaped base 15 facilitates wiring operations and reduces costs compared to a rectangular base 15.

[0035] Example 4 Reference Figures 6 to 10 This embodiment differs from the second embodiment in that the base 15 is arranged in a W shape.

[0036] Specifically, the W-shaped base 15 facilitates wiring operations, while reducing costs and space occupation compared to a rectangular base 15.

[0037] Example 5 Reference Figures 17 to 18This embodiment differs from the second embodiment in that it provides an anti-condensation system, which includes a temperature measurement unit 4, which includes an infrared temperature measurement module and a camera module, and the infrared temperature measurement module and the camera module are connected to a camera 34; an interaction unit 5, which includes a switch configured with a data forwarding module, a control board module and a management module, a server configured with hardware modules and software modules and a display, and the switch is connected to the infrared temperature measurement module and the camera module; and a dehumidification unit 6, which includes a temperature acquisition module, a humidity acquisition module, a PLC control module, a heating module, a dehumidification module and a cooling module, the temperature acquisition module and the humidity acquisition module are both connected to a temperature and humidity sensor 32, the PLC control module is connected to a PLC control panel 33, the dehumidification module and the cooling module are connected to a small air conditioner 35, and the PLC control module is connected to a fan 16.

[0038] Specifically, the heating module is connected to the heater 31 and the heating wire, the PLC control module is connected to the acquisition module and the temperature acquisition module, the PLC control module is connected to the heating module, the dehumidification module and the refrigeration module, and the server establishes a signal connection with the switch and the display. Infrared temperature measurement is performed on the working equipment (excluding the main substation equipment such as heater 31, heating wire, and small air conditioner 35) installed inside the enclosure 11 using an infrared temperature measurement module. Real-time images of the working equipment inside the enclosure 11 are collected in real time using a camera module. The data forwarding module is responsible for transmitting the collected data. The control board module ensures signal stability. The management module classifies and distributes the data. The server carries the data storage through a hardware module. The software module completes the data processing and analysis. The temperature data and real-time images of the equipment inside the enclosure 11 are displayed on a monitor. The temperature acquisition module and humidity acquisition module are used to collect temperature and humidity data inside the enclosure 11 in real time, and transmit the collected temperature and humidity data to the PLC control module.

[0039] During use, the temperature measurement unit 4 collects real-time temperature data and operating images of the equipment inside the enclosure through the infrared temperature measurement module and camera module of camera 34. The data is then transmitted to the server via the data forwarding module of the switch. The server analyzes and processes the data through the software module and displays the equipment temperature and image information intuitively on the monitor for easy real-time monitoring by staff. At the same time, the temperature acquisition module and humidity acquisition module collect temperature and humidity data inside the enclosure and transmit them to the PLC control module. The PLC control module automatically adjusts the operation of each component according to the preset temperature and humidity thresholds through the PLC control panel. When the humidity is higher than the threshold, the dehumidification module is activated to dehumidify. Condensate is discharged from the outlet pipe 38 through the drain pipe 36 and the water collection tank 37. The fan 16 is activated through the PLC control module to exhaust air and prevent moisture from accumulating in the wiring trough 22. When the temperature is lower than the threshold, the heating module is activated to keep the temperature warm. In summer, when the temperature is too high, the cooling module is activated to cool down the temperature, ensuring that the equipment inside the enclosure is always in a suitable operating environment.

[0040] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
