It is more common in areas with well-developed water systems, abundant rainfall, and distinct four seasons, such as Jiangsu, Zhejiang, and Shanghai. Condensation can not only cause misconnection of the RMU secondary compartment terminal blocks, leading to tripping accidents, but can also corrode the RMU switch mechanism, causing the actual service life of the equipment to be far less than its designed life.

[0003] For example, Chinese patent publication number CN112886398A discloses an external ring main unit (RMU) dehumidification and anti-condensation device.

[0031] When the humidity is greater than a first preset value and less than a second preset value, the dehumidification guide mechanism and the regeneration guide mechanism are controlled to operate, and the rotor in the dehumidification rotor rotates at a preset angle at a preset interval so that the first area corresponds to the dehumidification area and the second area corresponds to the regeneration area. After the preset time, the second area corresponds to the dehumidification area and the first area corresponds to the regeneration area.

[0032] When the humidity is greater than the second preset value, the first branch pipe of the dehumidification guide mechanism is connected, and part of the dried air flow is transported to the ring network cabinet through the first air outlet pipe; the other part of the dried gas is transported to the heater through the first branch pipe.

[0039] Compared with the prior art, the present invention discloses a rotary dehumidification device for humidity control of a ring main unit, comprising a dehumidification rotary wheel, a dehumidification guide mechanism, a heating mechanism, and a regeneration guide mechanism, which are used in combination with each other to play a role.

[0040] When the humidity in the ring network cabinet is greater than the first preset value and less than the second preset value: close the first valve, and the air flow first enters from the first air inlet pipe, flows through the filtering mechanism, the dehumidification area, the heating mechanism, the dehumidification fan, and finally flows into the ring network cabinet from the first air outlet pipe to achieve air drying; when the humidity in the ring network cabinet is greater than the second preset value: connect the first branch pipe, and part of the dried air flow is transported to the ring network cabinet through the first air outlet pipe; the other part of the dried gas is transported to the heater through the first branch pipe so that part of the dry air is heated and takes away the remaining moisture. The dehumidification wheel, the dehumidification guide mechanism, the heating mechanism, and the regeneration guide mechanism cooperate with each other to achieve full drying and regeneration of the dehumidification wheel, ensuring the adsorption capacity and drying effect. The area switching of the dehumidification wheel and the on-off coordination of the first valve or the second valve change the direction of the airflow, which can avoid insufficient regeneration of the dehumidification wheel affecting the dehumidification effect when it is greater than the second preset value, thereby improving the subsequent adsorption capacity of the wheel.

[0070] A ring main unit dehumidification method comprises the following steps:

[0071] Detect the humidity inside the ring network cabinet;

[0072] When the humidity is greater than a first preset value and less than a second preset value, the dehumidification guide mechanism 2 and the regeneration guide mechanism 4 are controlled to operate, and the rotor 12 in the dehumidification rotor 1 rotates at a preset angle at a preset interval so that the first area 122 corresponds to the dehumidification area 111 and the second area 121 corresponds to the regeneration area 112. After the preset time, the second area 121 corresponds to the dehumidification area 111 and the first area 122 corresponds to the regeneration area 112.

[0074] When the humidity is greater than the first preset value and less than the second preset value, the specific working steps of controlling the dehumidification guide mechanism 2 and the regeneration guide mechanism 4 are as follows: a dehumidification fan 16 is added to the first air outlet duct 22 near the return air outlet, a filter mechanism 5 is added to the second air inlet duct 41 and the first air inlet duct 21 respectively, and a regeneration fan 17 is added to the second air outlet duct 42 near the second air outlet.

[0075] When the dehumidification fan 16 is turned on, the airflow from the first air outlet enters from the first air inlet pipe 21, is filtered by the filter mechanism 5, then enters the dehumidification area 111 and passes through the first area 122 on the rotor 12 for adsorption dehumidification. The airflow flowing out of the dehumidification area 111 then enters the preheating chamber 31 for heating, and then flows into the ring main unit through the dehumidification fan 16 from the first air outlet pipe 22.

[0076] At the same time, the regeneration fan 17 is turned on, and the airflow enters from the second air inlet pipe 41, flows through the filter mechanism 5 for filtration treatment, and then passes through the preheating chamber 31 into the heater 32. At this time, the second valve 43 is open and the first valve 231 is closed. The airflow is not connected with the airflow in the first air outlet pipe 22, and then enters the regeneration area 112, causing the second area 121 of the runner 12 to be regenerated, and finally flows from the second air outlet pipe 42 to the outside of the ring network cabinet through the regeneration fan 17.

[0077] The preheating chamber 31 is used to preheat the airflow in the second air inlet pipe 41 or the first air outlet pipe 22.

[0078] The heater 32 is used to heat the airflow entering the regeneration area 112. Both the preheating chamber 31 and the heater 32 adopt a wrapped heating device, which can continuously and constantly heat the airflow inside the corresponding pipelines.
