Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a moisture-proof substation that is easy to inspect. Background Technology

[0002] Substations are critical facilities in power systems, primarily used for voltage conversion and power distribution. They use transformers to convert high-voltage electricity generated by power plants into higher voltages suitable for long-distance transmission, or to reduce the voltage to a usable level when the electricity reaches the user. Substations also include equipment such as switches and circuit breakers to control the flow of electricity and protect circuits from damage. They play a vital role in the efficient transmission and distribution of electricity, ensuring the stability and security of the power supply.

[0003] Patent CN215071296U discloses a box-type substation with moisture-proof and dehumidification functions, including a box body with a ventilation duct fixedly connected to the top of the inner cavity. Although good heat dissipation and dehumidification functions are achieved through the coordinated work of components such as the ventilation duct, exhaust box, temperature and humidity sensor, heat sink, and moisture-absorbing sponge, the structural design of the moisture-absorbing sponge being fixedly connected to both sides of the heat sink makes it difficult to easily replace the saturated sponge after long-term use, thus affecting the continuous moisture-proof effect.

[0004] Therefore, a moisture-proof substation that is easy to inspect is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, where the moisture-absorbing sponge is fixedly connected to both sides of the heat dissipation frame, making it difficult to replace the saturated moisture-absorbing sponge after long-term use and thus affecting the continuous moisture-proof effect, this utility model provides a moisture-proof substation that is easy to inspect.

[0006] The technical solution of this utility model is as follows: a moisture-proof substation that is easy to inspect, comprising a housing, a rainproof top cover, a protective door, hinges, a transformer, and a ring main unit. A rainproof top cover is fixedly connected to the top of the housing. Multiple hinges are installed on the front side of the housing, with two vertically aligned hinges jointly mounting the protective door. A transformer and a ring main unit are installed inside the housing. The system also includes a first fan, a dustproof plate, an absorbent sponge, a fixing plate, a slider, a fixing seat, a guide seat, a guide protrusion, a movable locking block, a fixing block, a limiting block, and an elastic element. A dustproof plate is slidably installed on the rear side of the housing, and a [missing information - likely a component or element] is placed inside the dustproof plate. The absorbent sponge has a fixed plate fixedly connected to the front of the box, and multiple first fans are installed on the front of the fixed plate. Slider is installed on both sides of the dustproof plate. Two fixed seats are fixedly connected inside the box, and guide seats are fixedly connected to the fixed seats. Two guide grooves are opened on the guide seats. Guide protrusions are fixedly connected to the upper and lower sides of the slider. The guide protrusions slide on the guide grooves. A fixed block is fixedly connected to the guide seat. A movable locking block is rotatably set on the fixed block. A limit block is fixedly connected to the rear end of the movable locking block. A limit groove is opened on the slider. The limit block slides on the limit groove. An elastic element connects the slider and the guide seat.

[0007] Furthermore, it also includes limit switches, limit rods, and LED lights. A limit switch is installed at the bottom of the enclosure, and a limit rod is slidably installed in front of the limit switch. Two LED lights are installed on the left side of the enclosure, and the LED lights are electrically connected to the limit switches.

[0008] Furthermore, it also includes a dehumidifier housing, a filter screen, a second fan, an evaporator, a condenser, and a guide pipe. The dehumidifier housing is installed on the left side inside the housing. Filter screens are embedded on both the front and rear sides of the dehumidifier housing. Two second fans are installed inside the dehumidifier housing. An evaporator and a condenser are installed inside the dehumidifier housing. A guide groove is opened at the bottom of the dehumidifier housing. A guide pipe is connected to and communicates with the bottom of the dehumidifier housing.

[0009] Furthermore, it also includes a humidity sensor, which is installed on the top of the dehumidifier housing and is electrically connected to the evaporator and condenser.

[0010] Furthermore, a groove is provided on the front side of the protective door.

[0011] Furthermore, it also includes a glass window, with a glass window embedded in the front side of the protective door.

[0012] Compared with the prior art, this utility model provides a moisture-proof substation that is easy to inspect, and has the following beneficial effects:

[0013] 1. By pushing the slider backward and stretching the elastic element, the dustproof plate slides backward, exposing the absorbent sponge placed inside the dustproof plate. The old absorbent sponge is removed, and a new absorbent sponge is placed inside the dustproof plate. The slider is then released, and the elastic element rebounds, causing the slider and dustproof plate to move forward and reset. This allows for easy replacement of the absorbent sponge, preventing it from becoming saturated and losing its absorbent function, thus ensuring the moisture-proof effect.

[0014] 2. When the protective door is opened, the protective door will no longer press the limit rod. After the limit rod resets, it will trigger the limit switch, thereby connecting the circuit and turning on the LED light inside the box to illuminate the inside of the box for easy inspection.

[0015] 3. Through the coordinated operation of the second fan, evaporator and condenser, humid air inside the chamber is extracted and processed to remove moisture, keep the air dry, effectively reduce the humidity inside the chamber and protect the equipment from the effects of moisture.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example 1: A moisture-proof substation that facilitates inspection; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 4 and Figure 5 The enclosure includes a housing 1, a rainproof top cover 2, a protective door 3, hinges 4, a transformer 7, and a ring main unit 9. The rainproof top cover 2 is fixedly connected to the top of the housing 1, preventing external rainwater from entering. Four hinges 4 are installed on the front of the housing 1, with two vertically aligned hinges 4 sharing the protective door 3. The transformer 7 and the ring main unit 9 are installed inside the housing 1. A dustproof plate 20 is slidably installed on the rear of the housing 1, with absorbent sponges 21 placed inside. A fixing plate 22 is fixedly connected to the front of the interior of the housing 1, with four first fans 8 installed on the front of the fixing plate 22. Sliding blocks 23 are installed on both sides of the dustproof plate 20. Two fixing seats 24 are fixedly connected inside the housing 1, with guides fixedly connected to the fixing seats 24. The guide seat 25 has two guide grooves 2501. The slider 23 has guide protrusions 2502 fixedly connected to both the upper and lower sides. The guide protrusions 2502 slide on the guide grooves 2501. The guide seat 25 has a fixed block 2601 fixedly connected to it. The fixed block 2601 has a movable locking block 26 rotatably set on it. The rear end of the movable locking block 26 is fixedly connected to a limit block 2602. The slider 23 has a limit groove 27. The limit block 2602 slides on the limit groove 27. An elastic element 28 connects the slider 23 and the guide seat 25. The protective door 3 has a groove 5 on the front side. The groove 5 is used to increase the force point between the hand and the protective door 3, making it easier to rotate the protective door 3. The protective door 3 has a glass window 6 embedded on the front side, which makes it easy to see the inside of the box 1.

[0024] When the substation is in use, the first fan 8 is started. The operation of the first fan 8 promotes airflow. External air is filtered by the dust filter 20 to remove dust. The absorbent sponge 21 absorbs moisture and impurities from the air, preventing moisture from entering the enclosure 1 and reducing humidity inside the enclosure, thus achieving moisture prevention. The filtered air enters the enclosure 1, accelerating airflow and dissipating heat inside the enclosure 1 to prevent overheating from affecting the normal operation of the substation. When the absorbent sponge 21 needs to be replaced, the slider 23 is pushed backward and the elastic element 28 is stretched. At this time, the movable locking block 26 rotates, causing the limit block 2602 to slide along the limit groove 27, releasing the sliding block. When block 23 is stopped, slider 23 moves backward, causing dustproof plate 20 to slide backward, exposing the absorbent sponge 21 placed inside dustproof plate 20. The old absorbent sponge 21 is removed, and a new absorbent sponge 21 is placed inside dustproof plate 20. Slider 23 is released, and elastic element 28 rebounds, causing slider 23 and dustproof plate 20 to move forward and reset. At this time, movable locking block 26 rotates again, causing limiting block 2602 to move along limiting groove 27, re-limiting slider 23 and fixing dustproof plate 20 to the rear side of box 1. In this way, absorbent sponge 21 can be easily replaced, preventing absorbent sponge 21 from becoming saturated and losing its adsorption function, thus ensuring the moisture-proof effect.

[0025] Example 2: Based on Example 1, please refer to... Figure 2 A limit switch 10 is installed at the bottom of the box 1. A limit rod 11 is slidably installed on the front side of the limit switch 10. Two LED lights 12 are installed on the left side inside the box 1. The LED lights 12 are electrically connected to the limit switch 10.

[0026] When the protective door 3 is opened, the protective door 3 no longer presses the limit rod 11. After the limit rod 11 is reset, it triggers the limit switch 10, thereby connecting the circuit and turning on the LED light inside the box to illuminate the inside of the box 1 for easy inspection. When the protective door 3 is closed, the protective door 3 presses the limit rod 11 again, and the limit rod 11 pushes the limit switch 10 to disconnect the circuit and turn off the LED light.

[0027] Please see Figure 2 and Figure 3Inside the housing 1, on the left side, is a dehumidifier housing 13. Filters 14 are embedded on both the front and rear sides of the dehumidifier housing 13. Two second fans 15 are installed inside the dehumidifier housing 13. An evaporator 16 and a condenser 17 are also installed inside the dehumidifier housing 13. A guide channel 18 is provided at the bottom of the dehumidifier housing 13, and a guide pipe 19 is connected to the bottom of the dehumidifier housing 13. The guide pipe 19 is connected to an external water tank. A humidity sensor 29 is installed at the top of the dehumidifier housing 13. The humidity sensor 29 is electrically connected to the evaporator 16 and the condenser 17. The humidity sensor 29 monitors the humidity inside the housing in real time and controls the evaporator 16 and the condenser 17 to automatically start and stop, maintaining a dry environment.

[0028] When the surrounding environment is humid, the second fan 15, evaporator 16, and condenser 17 are activated. The second fan 15 draws humid air from the chamber into the dehumidifier housing 13. The air first flows through the evaporator 16, where the low-temperature refrigerant absorbs heat from the air, causing the air temperature to drop rapidly below the dew point. Water vapor in the air condenses into water droplets upon contact with the condenser and adheres to the fin surface of the evaporator 16. The water is then discharged into the external water tank through the guide channel 18 and guide pipe 19. The dried air, after being cooled and dehumidified by the evaporator 16, then flows through the condenser 17. At this time, the condenser 17 becomes hot due to the release of heat from the high-temperature refrigerant. The air is heated and its temperature rises, so it is sent back into the housing 1 to maintain dryness, thereby reducing air humidity and preventing moisture from corroding the internal equipment of the housing 1.

All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
