Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a device for monitoring and removing condensation on outdoor power equipment. Background Technology

[0002] During power system operation, outdoor power equipment such as ring main units and branch boxes are exposed to the elements for extended periods, making them susceptible to natural factors such as rain, snow, high humidity, and diurnal temperature variations. When the internal humidity of the equipment increases, a sudden drop in temperature can easily cause condensation to form on the metal components, electrical contacts, and insulation materials of the cabinet. Condensation can significantly reduce the insulation performance of the equipment, leading to problems such as short circuits and corrosion of metal components. In severe cases, it can even cause equipment shutdowns, posing a significant threat to the safe and stable operation of the power system.

[0003] Currently, the common dehumidification methods for outdoor power equipment are: one is to use a heating dehumidifier, which raises the internal temperature of the equipment by using a built-in heating element, thereby increasing the air's moisture-holding capacity and reducing condensation; the other is to use a fan exhaust dehumidifier, which forces the humid air out of the equipment while drawing in outside air to achieve air exchange and reduce internal humidity.

[0004] However, heating dehumidifiers only temporarily suppress condensation by raising the temperature, without fundamentally removing moisture from the equipment. When the outside temperature drops sharply or the heating element stops working, the internal temperature of the equipment also decreases, and water vapor in the air will quickly condense into dew on the surface of the low-temperature components. Furthermore, a prolonged high-temperature environment may accelerate the aging of the internal insulation materials and shorten the equipment's lifespan. When using a fan for dehumidification, if the outside humidity is high, the intake air still carries a large amount of water vapor, which cannot effectively reduce the humidity inside the equipment. In addition, the fan can only achieve simple air exchange and cannot effectively remove moisture from hidden areas such as corners and cable gaps, resulting in uneven dehumidification and the formation of localized high-humidity environments.

The second side plate 23 is mounted on the second mounting plate 242 and the third mounting plate 243, and is adjacent to the second connecting portion 245. The first side plate 22 has a plurality of first openings 221. The second side plate 23 has a plurality of second openings 231 opposite to the plurality of first openings 221. Preferably, the first openings 221 are located on the end of the first side plate 22 adjacent to the first mounting plate 241; the second openings 231 are located on the end of the second side plate 23 adjacent to the first mounting plate 241. Some moisture in the outdoor electrical equipment can enter the dehumidification assembly 2 through the first openings 221 and the second openings 231, and be discharged with the fan 26. Furthermore, the second side plate 23 also has a plurality of third openings 232 on the end away from the first mounting plate 241. The base plate 25 is mounted on the end of the mounting bracket 24 away from the first mounting plate 241, and the two ends of the base plate 25 are fixed to the first side plate 22 and the second side plate 23 respectively by connectors (e.g. screws).

[0036] Also refer to Figures 4 to 7The base plate 25 includes an outer plate 51, an inner plate 52, a U-shaped groove 53, a support 54, and a support plate 56. The outer plate 51 and the inner plate 52 are both approximately square. The inner plate 52 is positioned above the outer plate 51 and is inclined relative to it. Specifically, one vertex of the inner plate 52 is adjacent to one vertex of the outer plate 51, and the other three vertices of the inner plate 52 are spaced apart from the other three vertices of the outer plate 51. Preferably, the angle between the inner plate 52 and the outer plate 51 is 15°. The outer plate 51 has multiple first conductive holes 511. The inner plate 52 has multiple second conductive holes 521, and the second conductive holes 521 are opposite to the first conductive holes 511. The support 54 is positioned on the upper side of the inner plate 52, and the U-shaped groove 53 is mounted on the upper side of the inner plate 52 via the support 54. The U-shaped groove 53 is S-shaped on the upper side of the inner plate 52. The U-shaped groove 53 has multiple third conductive holes 531. The U-shaped groove 53 contains a desiccant. Preferably, the desiccant is a honeycomb activated carbon desiccant. Preferably, the inner diameter of the U-shaped groove 53 is 120 mm, the height is 200 mm, and the desiccant filled inside the cavity is a honeycomb silica gel desiccant with a particle size of 5-8 mm. Multiple limiting plates 532 are provided in the U-shaped groove 53, and the limiting plates 532 are connected between the two legs of the U-shaped groove. A notch 533 is provided on the upper side of the limiting plate 532, and a heating element (e.g., a heating wire) is engaged in the notch 533. Furthermore, a heating element (e.g., a PTC heating element) can be installed on the lower side of the U-shaped groove 53. For example, a 10W PTC heating element (temperature control range 50-60℃) is installed at the bottom of the U-shaped groove 53. The PTC heating element is linked to a temperature and humidity sensor. When the sensor detects that the desiccant humidity exceeds 60%RH, the heating element automatically starts to dry and regenerate the desiccant. The water vapor generated during the regeneration process enters the secondary condensation chamber through the exhaust port at the top of the primary dehumidification chamber. Support plates 56 are located on both sides of the outer plate 51 and extend vertically upwards relative to the outer plate 51. The inner plate 52 and support plates 56 form an inclined water guide channel. Since the inner plate 52 is inclined relative to the outer plate 51, the water guide channel is also inclined. Preferably, when the angle between the inner plate 52 and the outer plate 51 is 15°, the inclination angle of the water guide channel is also 15°. A dustproof net 29 is located on the inner side of the support plate 56 and above the U-shaped groove 53. Preferably, the aperture of the dustproof net 29 is 0.5mm. The base plate 25 also has mounting holes 55 penetrating the outer plate 51 and the inner plate 52, and the drain pipe 20 is installed in these mounting holes 55. Mounting hole 55 is located near the connection point of the corresponding apex of outer panel 51 and inner panel 52. Preferably, drain pipe 20 is a silicone drain hose. One end of drain pipe 20 is connected to a water guide channel, and the other end extends to the outside of the outdoor electrical equipment. Preferably, the other end of drain pipe 20 is equipped with a buoyancy-type water stop valve to prevent rainwater or moisture from flowing back into the outdoor electrical equipment.

[0037] Back Figure 4 and Figure 5 The first connecting portion 244 and the second connecting portion 245 of the mounting bracket 24 are arranged parallel to each other, and both the first connecting portion 244 and the second connecting portion 245 are inclinedly connected between the second mounting plate 242 and the third mounting plate 243. Specifically, the distance between the end of the first connecting portion 244 adjacent to the second mounting plate 242 and the side of the second mounting plate 242 away from the first mounting plate 241 is greater than the distance between the end of the first connecting portion 244 adjacent to the third mounting plate 243 and the side of the third mounting plate 243 away from the first mounting plate 241; the distance between the end of the second connecting portion 245 adjacent to the second mounting plate 242 and the side of the second mounting plate 242 away from the first mounting plate 241 is greater than the distance between the end of the second connecting portion 245 adjacent to the third mounting plate 243 and the side of the third mounting plate 243 away from the first mounting plate 241. Furthermore, a plurality of first ribs 246 connect the first connecting portion 244 to the first mounting plate 241; a plurality of second ribs 247 connect the second connecting portion 245 to the first mounting plate 241. The first ribs 246 and the second ribs 247 can respectively improve the stability of the first connecting portion 244 and the second connecting portion 245. The condensate plate 28 is mounted on the first connecting portion 244 and the second connecting portion 245 of the mounting frame 24. Thus, the condensate plate 28 is mounted on the mounting frame 24 at an angle relative to the first mounting plate 241. Preferably, the condensate plate 28 is a ceramic condensate plate or an aluminum condensate plate with dimensions of 150mm × 80mm × 5mm. More preferably, three condensate plates 28 arranged vertically are installed in the secondary condensation chamber, with a plate spacing of 30mm. Preferably, the condensate plate 28 has a plurality of perforations.

[0038] The top plate 21 is mounted on the outer side of the first mounting plate 241 of the mounting bracket 24. Preferably, an opening 411 is provided in the middle of the first mounting plate 241, and the top plate 21 covers the opening 411. Multiple heat dissipation holes 211 are provided on the top plate 21. The fan 26 is mounted on the first mounting plate 241 adjacent to the top plate 21. A heat sink 27 is disposed between the fan 26 and the cold condensate plate 28. Preferably, there are two fans. More preferably, the fans are 12V DC brushless fans (airflow rate of 80 m³ / h).

[0039] When fan 26 starts, the humid air inside the outdoor power equipment is first drawn into the primary dehumidification chamber, where it is adsorbed by the desiccant for primary moisture adsorption. Then, it enters the secondary condensation chamber, where the moisture condenses into water droplets on the surface of the low-temperature condensate plate 28 for secondary condensation. The water droplets slide down the condensate plate 28 to the bottom water guide trough, and the condensate in the trough is discharged outside the outdoor power equipment through drain pipe 20. When the temperature and humidity sensor in the primary dehumidification chamber detects that the desiccant humidity is ≥60%RH, the heating element starts to dry and regenerate the desiccant. The regeneration time is set to 30 minutes, and the heating element automatically shuts off after regeneration. When the internal humidity is ≤50%RH and there is no condensation, the dual-stage dehumidification module of the dehumidification component stops working, and the device enters standby mode, with only the intelligent monitoring module running to reduce energy consumption. Furthermore, the condensation monitoring and removal device is equipped with overcurrent and overtemperature protection modules. When the temperature of the heating element exceeds 70℃ or the fan current exceeds 0.5A, the power supply to the corresponding component is immediately cut off to ensure safe operation of the device.
