DETAILED DESCRIPTION

[0024] Therefore, in order to solve the technical problems that high temperature causes water droplets to condense on the surface of the equipment, reduces the insulation performance of the insulation material, increases the risk of short circuit of the equipment, and reduces the operation efficiency of the equipment in the related art, the embodiment of the present application provides the following solutions.

[0025] Please refer to Figures 1 to 6This application provides an intelligent ring main unit, which includes a housing 1, a cover 11, a base plate 12, a ring main unit 13, a dehumidification component 2, and a heat dissipation component 4. The housing 1 is mounted on the base plate 12, the cover 11 is mounted on the housing 1, the ring main unit 13 is mounted inside the housing 1, the heat dissipation component 4 is mounted on the housing 1, and the dehumidification component 2 is mounted on the housing 1.

[0026] In some embodiments, please refer to the following: Figures 3 to 5 The dehumidification assembly 2 includes an air inlet pipe 21, a dehumidification box 22, an air outlet pipe 23, an exhaust fan 24, dehumidifying particles 25, and an air diffuser 26. The dehumidification box 22 is mounted on the housing 1. One end of the air inlet pipe 21 is mounted on the housing 1, and the other end of the air inlet pipe 21 is mounted on the dehumidification box 22. The air diffuser 26 is mounted on the end of the air inlet pipe 21 near the dehumidification box 22. The exhaust fan 24 is mounted on the dehumidification box 22. The dehumidifying particles 25 are mounted on the dehumidification box 22 and are positioned above the dehumidifying particles 25. The air outlet pipe 23 is mounted on the dehumidification box 22. A connecting plate 5 is installed inside the housing 1. The ring network cabinet 13 is mounted inside the housing 1 through the connecting plate 5. Multiple through holes 51 are opened on the connecting plate 5. An inclined plate 52 is installed on the housing 1. Multiple water inlets 53 are opened on the inclined plate 52. A drain pipe 14 is installed on the housing 1.

[0027] With this setup, when the intelligent ring main unit is used outdoors, the ring main unit 13 generates heat when the outdoor temperature is relatively cold, and produces water mist when the climate is relatively humid. At the same time, the exhaust fan 24 starts working, drawing air out of the ring main unit 13 through the air inlet pipe 21. The air diffuser 26 can increase the airflow speed and improve the dehumidification efficiency. The dehumidifying particles 25 remove the water mist from the air and discharge it through the air outlet pipe 23. When water droplets condense on the box 1, the water droplets flow down the box 1 and flow through the through hole 51 on the connecting plate 5 to the inclined plate 52. The water is then guided to a lower position through the water channel 53 on the inclined plate 52 and discharged through the drain pipe 14 on the box 1. In cold and humid environments, water mist and condensation can easily cause short circuits or deterioration of insulation performance in electrical equipment. Dehumidification and drainage designs effectively prevent water mist and condensation from accumulating inside the equipment, thereby reducing the risk of short circuits and malfunctions, ensuring stable operation of the ring main unit, reducing moisture corrosion, and preventing rust on metal parts and aging of insulation materials due to humidity. This extends the equipment's lifespan, reduces replacement frequency, and lowers maintenance costs. The design of the induced draft fan 24 and the air diffuser 26 quickly removes humid air from the ring main unit, and dehumidifying particles 25 remove water mist, keeping the inside of the unit dry. This provides a good operating environment for the equipment, improving its operating efficiency. Because it effectively copes with harsh weather conditions and reduces equipment failures caused by humidity, it reduces downtime and improves the reliability and stability of power supply. The intelligent ring main unit, through its automatic dehumidification and drainage system, reduces the need for manual maintenance due to environmental changes, lowering the workload and maintenance costs for maintenance personnel.

[0028] In some embodiments, please refer to the following: Figure 2 The enclosure 1 is equipped with a detection component 3, which includes an infrared temperature sensor 31, a relay 32, an alarm 33, and a PLC controller 34. The infrared temperature sensor 31 is located on the side of the enclosure 1 closest to the ring main unit 13, the relay 32 is located on the side of the enclosure 1 closest to the ring main unit 13, the alarm 33 is located on the side of the enclosure 1 away from the ring main unit 13, and the PLC controller 34 is located on the side of the enclosure 1 closest to the ring main unit 13.

[0029] With this setup, if the temperature inside the ring main unit 13 is too high during use, the infrared temperature sensor 31 can be easily detected by the detection component 3. When the temperature is high, the infrared temperature sensor 31 can transmit the signal to the PLC controller 34 through the relay 32. The PLC controller 34 can then control the alarm 33 to sound an alarm, so that the alarm 33 can alert the staff. Thus, the infrared temperature sensor 31 can monitor the temperature changes inside the ring main unit 13 in real time. When the temperature rises abnormally, it can quickly detect and send a signal. This rapid response capability can avoid equipment damage or failure caused by excessive temperature, reducing the probability of accidents. The infrared temperature sensor 31 can detect the temperature in different areas inside the ring main unit 13, helping staff to accurately locate the parts with abnormally high temperatures, thereby quickly finding the source of the fault and improving maintenance efficiency. Electrical equipment inside the ring main unit 13 is prone to insulation aging, short circuits, and even fires in high-temperature environments. Through the temperature monitoring and alarm system, staff can be promptly reminded to take measures when the temperature is too high to avoid equipment damage due to overheating and extend the service life of the equipment. The PLC controller 34 can perform real-time analysis and processing based on the data from the infrared temperature sensor 31 to achieve real-time monitoring of the operating status of the ring main unit 13. When the temperature approaches the set safety threshold, it can issue an early warning to remind staff to take preventive measures to prevent the temperature from rising further.

[0030] In some embodiments, please refer to the following: Figure 3 The heat dissipation component 4 includes a fan motor 41, a cooling fan 42, and a cold air box 43. The cold air box 43 is mounted on the housing 1. An air inlet plate 44 is provided at the end of the cold air box 43 away from the ring main unit 13, and an air outlet plate 45 is provided at the end of the cold air box 43 close to the ring main unit 13. The fan motor 41 is mounted on the air inlet plate 44, and the cooling fan 42 is mounted on the fan motor 41. The output shaft of the cooling fan 42 and the fan motor 41 are coaxially driven. A protective cover 46 is provided on the side of the air outlet plate 45 away from the cooling fan 42. Multiple ventilation holes are provided on the housing 1, and multiple ventilation plates 15 are provided on the end of the housing 1 away from the ring main unit 1 through the ventilation holes.

[0031] With this configuration, when the temperature inside the enclosure 1 is too high, the PLC controller 34 can control the fan motor 41 to work, which facilitates heat dissipation inside the enclosure 1, thereby reducing the temperature inside the enclosure 1 and preventing the circuit inside the enclosure 1 from malfunctioning due to excessive temperature. The fan motor 41 drives the cooling fan 42 to rotate, which quickly removes the heat inside the enclosure through forced convection, while introducing cool air from outside the enclosure to form a thermal convection cycle. The protective cover 46 helps protect the inside of the enclosure 1 in harsh windy environments, preventing rainwater from entering and damaging the inside of the ring main unit 13. The ventilation plate 15 and ventilation holes can assist in cooling, while also preventing water vapor from occurring due to excessive temperature difference between the inside and outside of the enclosure. Thus, when the temperature inside the enclosure 1 is too high, the PLC controller 34 can promptly start the fan motor 41. Through the forced convection of the cooling fan 42, the heat inside the enclosure is quickly dissipated. This active cooling method is more efficient than natural cooling and can reduce the temperature inside the enclosure 1 in a short time, avoiding equipment failure caused by high temperature. The cooling fan 42 not only exhausts hot air but also introduces cold air from outside the enclosure, forming a thermal convection cycle. This cycle can continuously reduce the temperature inside the enclosure 1, maintain a stable environment inside the enclosure, and provide good operating conditions for the equipment. High temperature is one of the important causes of electrical equipment circuit failures, such as insulation aging and short circuits. Through effective heat dissipation measures, the temperature inside the enclosure 1 can be reduced, reducing the risk of circuit damage due to high temperature, thereby ensuring the safe operation of the equipment. In harsh environments such as strong winds and heavy rain, the protective cover 46 can effectively prevent rainwater from entering the enclosure 1, avoiding problems such as short circuits and corrosion caused by rainwater, and enhancing the environmental adaptability of the ring main unit 13.

[0032] The implementation principle of the intelligent ring main unit in this application embodiment is as follows: During the outdoor use of the intelligent ring main unit, in cold outdoor conditions, the ring main unit 13 generates heat during operation. In humid conditions, water mist is generated. At the same time, the exhaust fan 24 starts working, drawing air out of the ring main unit 13 through the air inlet pipe 21. The air diffuser 26 increases the airflow velocity and improves dehumidification efficiency. The dehumidifying particles 25 remove the water mist from the air and discharge it through the air outlet pipe 23. When water droplets condense on the box body 1, the water droplets flow down the box body 1 and through the through holes 51 on the connecting plate 5 to the inclined plate 52. The water is then guided to a lower position by the water channel 53 on the inclined plate 52 and discharged through the drain pipe 14 on the box body 1. If the temperature of the ring main unit 13 is too high during use, the detection component 3, which is equipped with an infrared temperature sensor 31, can easily detect the temperature inside the box body 1. When the temperature is high, the infrared temperature sensor 31 can transmit the signal to the PLC controller 34 through the relay 32. The PLC controller 34 can control the alarm 33 to sound an alarm, so that the alarm 33 can alert the staff. When the temperature inside the cabinet 1 is too high, the PLC controller 34 can control the fan motor 41 to work, so as to dissipate heat from the inside of the cabinet 1, reduce the temperature inside the cabinet 1, and prevent the circuit inside the cabinet 1 from malfunctioning due to excessive temperature. The fan motor 41 drives the cooling fan 42 to rotate, and quickly expel the heat inside the cabinet through forced convection, while introducing cold air from outside the cabinet to form a thermal convection circulation. The protective cover 46 helps to protect the inside of the cabinet 1 in harsh wind environments, preventing rainwater from entering and damaging the inside of the ring main unit 13. The ventilation plate 15 and ventilation holes can assist in cooling, and at the same time prevent water mist caused by excessive temperature difference between the inside and outside of the cabinet.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
