Description

Technical Field

[0001] The present invention relates to the technical field of ring main unit, and in particular to an anti-condensation device and a ring main unit system. Background Art

[0002] Ring main unit is a group of electrical equipment (high voltage switchgear) installed in a metal or non-metallic insulated cabinet or assembled into a spaced ring main unit. The core of the ring main unit uses load switches and fuses, which have the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. Ring main units are widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, and load centers such as factories and enterprises.

[0003] The ring network cabinet installed outdoors needs to be equipped with an anti-condensation device. When the air is taken in, the gas will be filtered through the filter. After long-term use, a large amount of dust will be adsorbed on the filter. If it is not cleaned in time, the air intake will be reduced, which is not conducive to the heat dissipation inside the ring network cabinet. In addition, the anti-condensation device of the ring network cabinet installed outdoors is equipped with a dehumidification mechanism, which can directly discharge the water vapor after condensation, and the condensed water cannot be collected and reused, resulting in a waste of resources. In addition, a large amount of water droplets will be adsorbed on the inner wall of the dehumidification mechanism in the existing anti-condensation device, which cannot fall down in time for collection. When the ambient temperature is high, the water droplets adsorbed on the inner wall of the dehumidification mechanism may evaporate again, increasing the working pressure of the dehumidification mechanism.

[0004] In addition, the heat dissipation effect of the existing anti-condensation device of the ring network cabinet is poor. When the temperature inside the ring network cabinet rises abnormally, the ventilation component alone cannot cool it down in time, which can easily cause high-temperature damage to the internal parts of the ring network cabinet.

[0058] Figure 5 A transverse cross-sectional view of the ring main unit system provided by an embodiment of the present invention at the connection point between the ring main unit body 10 and the anti-condensation device is shown; Figure 6 Show Figure 5 A partial enlarged view of the structure marked with C. Figure 1-Figure 3 , Figure 5 and Figure 6 The air intake mechanism 100 includes an air intake housing 110 and a filter assembly 120. The filter assembly 120 is a plate-shaped structure, which is arranged in the air intake housing 110 at an angle to the vertical direction, located at the rear end of the air intake port of the air intake housing 110, and can filter external air.

[0059] Specifically, the dehumidification mechanism 200 includes a condensation shell 210, a refrigerator 220 and a condensation water collection component 230. The condensation shell 210 is connected between the air intake mechanism 100 and the ring network cabinet 10. The refrigerator 220 is arranged on the condensation shell 210, and can cool the internal space of the condensation shell 210. In this embodiment, the refrigerator 220 can specifically select a semiconductor refrigerator, which can produce cold energy by using the thermal-electric effect of semiconductors. Water in the external gas can condense in the condensation shell 210, and the condensation water collection component 230 is a box structure, which is connected to the condensation shell 210 and can collect condensation water in the condensation shell 210.

[0060] More specifically, the condensation housing 210 includes a condensation housing 211 and a partition assembly 212. The partition assembly 212 is disposed in the condensation housing 211, and the refrigerator 220 is disposed on the condensation housing 211. In this embodiment, the partition assembly 212 includes a U-shaped portion and a straight plate portion, and the U-shaped portion and the straight plate portion are arranged in the condensation housing 211 at intervals to form an "S"-shaped curved airflow path in the space between the inlet and the outlet of the condensation housing 211, so as to increase the residence time of the external gas in the condensation housing 211 and improve the condensation and water removal effect.

[0061] More specifically, the vibration mechanism 400 includes a wind-driven member 410, a striking member 420 and a vibrating member 430. The wind-driven member 410 is disposed on the top outer side of the condensation housing 211, and the compressed air in the air extraction mechanism 300 can be guided to the side of the wind-driven member 410, and the wind-driven member 410 can rotate under the action of the compressed air in the air extraction mechanism 300. The vibrating member 430 is connected to the air intake mechanism 100, and the air intake mechanism 100 is connected to the filter assembly 120. The striking member 420 is connected to the wind-driven member 410, and can rotate under the drive of the wind-driven member 410 to periodically strike the vibrating member 430, so that the filter assembly 120 vibrates, thereby shaking off impurities such as dust or lint accumulated thereon, and ensuring the passability of external air in the filter assembly 120.

[0062] More specifically, the filter assembly 120 and the U-shaped portion are rigidly connected via a connecting rod 121. The U-shaped portion and the straight plate portion are connected via a connecting column 213. The above arrangement enables the filter assembly 120, the U-shaped portion and the straight plate portion to be connected as one body. When the filter assembly 120 vibrates, the vibration force can be transmitted to the U-shaped portion via the connecting rod 121, and then transmitted to the straight plate portion via the connecting column 213, so that the U-shaped portion and the straight plate portion together with the filter assembly 120 vibrate together, thereby shaking off the condensed water droplets accumulated on the U-shaped portion and the straight plate portion, thereby avoiding the problem of increasing the working pressure of the dehumidification mechanism 200 due to the evaporation of the condensed water droplets again.

The second chamber 512 is connected to the condensed water collection assembly 230 through the condensed water pipe 514, and is selectively connected to the spray assembly 520 through the spray valve 523. The condensed water in the condensed water collection assembly 230 can enter the second chamber 512 through the condensed water pipe 514. The piston member 513 can move under the action of the pressure difference between the first chamber 511 and the second chamber 512. When the air pressure in the first chamber 511 is greater than the pressure in the second chamber 512, the piston member 513 moves upward. At this time, the spray valve 523 is opened to supply the condensed water in the second chamber 512 to the spray assembly 520.

[0064] Specifically, the spray assembly 520 includes a connecting water pipe 521 and a plurality of spray heads 522.

Through the above arrangement, the ring network cabinet 10 can be sprayed with water in multiple directions to improve the uniformity and cooling rate of the cooling using the evaporative heat dissipation principle.

A flushing valve 141 is provided at the inlet of the flushing pipe 140, and the flushing pipe 140 is selectively connected to the second chamber 512 through the flushing valve 141. The outlet of the flushing pipe 140 extends into the air intake housing 110 and faces the filter assembly 120. When the flushing valve 141 is opened and the pressure in the first chamber 511 is greater than the pressure in the second chamber 512, the water in the second chamber 512 can be introduced into the air intake housing 110 through the flushing pipe 140 to flush the filter assembly 120. Through the above arrangement, in combination with the vibration of the vibrating member 430, the cleaning effect of the filter assembly 120 is further enhanced, which not only alleviates the clogging of the filter assembly 12, but also reduces the frequency of manual cleaning.
