Description

Technical Field

[0001] This invention relates to the field of ring network box technology, specifically to an environmentally friendly gas-type primary and secondary fusion standardized ring network box. Background Technology

[0002] Ring main units are commonly used outdoor power distribution facilities in urban power distribution networks. They are mainly used to house gas-insulated ring main units, cable accessories, and secondary control equipment. They are widely used in densely loaded areas such as residential communities, commercial centers, and industrial parks. To meet environmental protection requirements, the traditional scheme using SF6 gas as the insulating medium is gradually being replaced by environmentally friendly gas-insulated ring main units. They are often integrated with primary and secondary integrated power distribution terminals to achieve power distribution automation and status monitoring.

[0003] Existing ring main units typically employ a metal enclosed structure, relying on natural heat dissipation from the surface of the unit or forced cooling by a fan installed on top. However, ring main units are exposed to the outdoor environment for extended periods, and in summer, solar radiation can easily create a greenhouse effect inside the unit, leading to a significant increase in temperature in the high-voltage compartment and equipment room. Conventional natural heat dissipation methods have limited cooling capacity, while forced cooling by fans requires additional electrical energy. Furthermore, fans have low reliability over long-term operation and are prone to failure in high-temperature, high-humidity, and dusty environments, increasing maintenance costs. In addition, to meet protection standards, the air inlets and outlets of ring main units are usually small or equipped with complex filtration structures, making it difficult for hot air to be discharged in a timely manner, which can easily lead to localized overheating inside the unit. Summary of the Invention

Ribs are provided on the side surface of the box facing the outward-protruding top plate. The exhaust port is opened on the side of the heat collection cavity near the outward-protruding top plate and is arranged with the ribs.

[0007] As a preferred technical solution of this application, a partition is fixedly installed inside the box, which divides the inside of the box into a high-pressure chamber and a heat exchange chamber. A second ventilation groove is provided at both ends of the partition, and the second ventilation groove runs through the thickness direction of the partition to connect the airflow between the high-pressure chamber and the heat exchange chamber.

[0008] As a preferred technical solution of this application, it also includes a base, which includes an overhead mounting base and a plurality of support legs. The support legs are fixedly connected between the bottom of the box and the upper surface of the overhead mounting base. A grid plate is fixedly installed between adjacent support legs. The grid plate is located above the overhead mounting base and encloses to form a bottom air inlet channel.

[0009] As a preferred technical solution of this application, the overhead mounting base has a cavity inside, the cavity extends upward to the bottom air inlet channel area, the side wall of the overhead mounting base has an air inlet hole communicating with the outside, and the bottom surface of the box has a third ventilation slot.

[0010] As a preferred technical solution of this application, a heat exchange assembly is installed between the partition and the side wall of the box. The heat exchange assembly includes positioning shells respectively installed on the opposite surfaces of the partition and the box. A rotating shaft is rotatably installed between the opposing positioning shells. A bimetallic rotating spring is installed inside the positioning shell. The two ends of the bimetallic rotating spring are fixed to the positioning shell and the rotating shaft respectively. A sliding groove is opened on the bottom surface of the box. A sliding strip is installed in the sliding groove. A sliding pin is fixedly installed at one end of the sliding strip. A guide groove is opened on the outer circumference of the rotating shaft. The sliding pin is fitted into the guide groove. A heat exchange plate is fixedly installed at the other end of the sliding strip. The heat exchange plate is used to open and close the air inlet at the bottom of the box.

[0011] As a preferred technical solution of this application, the heat exchange plate includes an internally hollow shell, the heat exchange medium is encapsulated inside the shell, and the side surface of the shell facing the inside of the box has a plurality of arrayed concave and convex structures.

[0012] As a preferred technical solution of this application, a windproof grille is slidably installed on the inner side wall of the box door in the vertical direction, and a plurality of hollow ventilation holes are opened on the windproof grille.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1.

Combined with the necking structure of the throat, the exhaust flow rate is significantly improved. Without the need for external power supply and fan, a stable hot pressure suction channel is formed from bottom to top through the high pressure chamber, heat exchange chamber and heat collection chamber, which greatly reduces the temperature rise inside the chamber under high temperature conditions in summer.

[0014] 2. The low-level cavity inside the overhead mounting base provides a cold source with a temperature lower than the environment to the cabinet. With the help of the heat exchange plate driven by the bimetallic rotating spring and the windproof grille, the bottom cold source air intake is automatically opened and the air intake area of ​​the cabinet door is reduced when the temperature is high. When the temperature is low, the bottom air intake is closed and the basic ventilation of the cabinet door is maintained, thereby automatically switching the optimal heat dissipation mode under different ambient temperatures.

[0015] 3. The heat exchange medium encapsulated inside the heat exchange plate absorbs, stores, and releases heat when the temperature changes, thereby increasing the system's heat capacity, slowing down the rate of temperature rise and fall inside the box, preventing equipment from aging due to frequent thermal shocks, and helping to balance the risk of condensation caused by day-night temperature differences, further improving the reliability and stability of the ring main unit operation.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: The present invention provides a technical solution: such as Figures 1-11 The environmentally friendly gas-type primary and secondary fusion standardized ring network box shown includes a box body 10, a box door 11 is hinged to the opening of the box body 10, and a first ventilation slot 110 is provided on the box door 11 to realize the air circulation between the inside of the box body 10 and the outside.

[0020] A heat collection plate 20 is fixedly installed on the outer side of the back panel of the housing 10. The heat collection plate 20 and the back panel of the housing 10 enclose a heat collection cavity 201. The lower end of the heat collection cavity 201 is connected to the internal space of the housing 10, so that the air inside the housing 10 can enter the heat collection cavity 201. The upper end of the heat collection plate 20 extends to the top of the housing 10 and is provided with an exhaust port 202 for discharging the air inside the heat collection cavity 201 to the atmosphere.

[0021] Reference Figure 5A heat-absorbing plate 21 is fixedly installed inside the heat-collecting cavity 201. The heat-absorbing plate 21 is located in the middle area of ​​the heat-collecting cavity 201 and is used to absorb solar radiation heat. A glass plate 22 is fixedly installed on the heat-collecting plate 20 at the position corresponding to the heat-absorbing plate 21. The glass plate 22 and the heat-collecting plate 20 together form a greenhouse heat-collecting space. Under sunlight, the glass plate 22 allows short-wave radiation to enter and irradiate the heat-absorbing plate 21, while the long-wave radiation emitted by the heat-absorbing plate 21 after being heated is blocked by the glass plate 22. This creates a greenhouse effect in the heat-collecting cavity 201, making the air temperature inside the cavity significantly higher than the ambient temperature.

[0022] The heat collection chamber 201 is also provided with a throat section 203. The throat section 203 is located in the upper middle part of the heat collection chamber 201 and is set near the exhaust port 202. The flow cross-sectional area of ​​the throat section 203 is smaller than the flow cross-sectional area of ​​the upper and lower sections of the heat collection chamber 201, so that the inner wall of the heat collection chamber 201 forms a necking structure at the throat section 203. When the hot air in the heat collection chamber 201 flows upward and passes through the throat section 203, the airflow velocity is significantly increased due to the reduced flow cross-section, thereby enhancing the suction capacity driven by thermo-pressure.

[0023] Reference Figures 1-4 The top of the housing 10 is provided with an overhanging top plate 12. The horizontal projected area of ​​the overhanging top plate 12 is larger than the horizontal projected area of ​​the top of the housing 10. A ventilation gap is provided between the overhanging top plate 12 and the top of the housing 10. Ribs 13 are provided on the side surface of the housing 10 facing the overhanging top plate 12. The ribs 13 are located within the shielding range of the overhanging top plate 12 and are used to increase the heat exchange area. The exhaust port 202 is opened on the side of the heat collection cavity 201 near the overhanging top plate 12 and is arranged opposite the ribs 13. When the high-temperature air heated in the heat collection cavity 201 is discharged from the exhaust port 202, it directly washes the surface of the ribs 13, accelerating the air flow. Then the hot air diffuses outward along the lower surface of the overhanging top plate 12 and is finally discharged from the outer edge of the overhanging top plate 12. This avoids the heat backflow phenomenon caused by the vertical upward spray of hot air. The hot air diffuses outward along the lower surface of the top plate and is discharged smoothly from the outer edge of the top plate, which significantly enhances the overall passive heat dissipation capacity of the ring network box.

[0024] In summer or under high-temperature conditions, solar radiation heats the heat-absorbing plate 21 through the glass plate 22, causing the air temperature inside the heat collection cavity 201 to rise rapidly and its density to decrease. Under thermal pressure, a natural upward airflow is formed, creating a negative pressure suction at the lower end of the heat collection cavity 201. The air inside the box 10 enters from the lower end of the heat collection cavity 201, is further heated by the heat-absorbing plate 21, and flows upward. The flow velocity is accelerated when passing through the throat 203, and finally it is discharged at high speed through the exhaust port 202, washing over the ribs 13 below the cantilevered top plate 12, and then escapes from the outer edge of the top plate. A stable natural convection from bottom to top is formed inside the box 10, while the first ventilation slot 110 on the box door 11 continuously replenishes the outside cold air, thereby achieving efficient passive heat dissipation inside the ring network box.

[0025] Furthermore, a partition 14 is fixedly installed inside the housing 10, which divides the interior of the housing 10 into a high-pressure chamber and a heat exchange chamber. The lower end of the heat collection chamber 201 is connected to the lower part of the heat exchange chamber. Second ventilation slots 141 are respectively opened at both ends of the partition 14. The second ventilation slots 141 penetrate through the thickness direction of the partition 14 and are used to connect the airflow between the high-pressure chamber and the heat exchange chamber.

[0026] Under normal operating conditions, heat is generated in the high-pressure chamber due to the operation of the ring main unit, and the indoor temperature rises. Driven by the thermal pressure formed by the heat collection cavity 201, the external cold air enters the high-pressure chamber through the first ventilation slot 110 in sequence, and then flows into the heat exchange chamber through the second ventilation slot 141. Subsequently, it carries heat to the heat collection cavity 201 and is discharged from the exhaust port 202, thus forming a complete natural convection heat dissipation path that runs through the high-pressure chamber, the heat exchange chamber, and the heat collection cavity 201.

[0027] Example 2: Figures 8 to 9 As shown, this embodiment, based on embodiment one, further includes a base 30, which is used to raise the installation height of the box 10 and provide it with low-level cold source air intake conditions. The base 30 includes an overhead mounting base 31 and multiple support legs 32. The support legs 32 are fixedly connected between the bottom of the box 10 and the upper surface of the overhead mounting base 31, so that the box 10 is in an overhead state. A grille 33 is fixedly installed between adjacent support legs 32. The grille 33 is located above the overhead mounting base 31 and forms a bottom air intake channel. While ensuring structural strength, the grille 33 can effectively block debris and small animals from entering the air intake path.

[0028] The overhead mounting base 31 is a closed concrete body with an internal cavity 34 that extends upwards to the bottom air intake channel area. An air intake hole 35 is provided on the side wall of the overhead mounting base 31 to communicate with the outside. Cold air from the outside can enter the cavity 34 through the air intake hole 35 and form a low-temperature cold source after being cooled by the concrete wall. A third ventilation slot 111 is provided on the bottom surface of the box 10. Due to the large thermal inertia and shading effect of the overhead mounting base 31, the air temperature inside the cavity 34 is usually lower than the external ambient temperature, thus providing a low-temperature cooling air source for the box 10.

[0029] Under normal operating conditions, the heat generated by the operation of the high-voltage indoor ring main unit raises the temperature inside the box. The heat collection cavity 201 forms a continuous thermal pressure under the combined effect of the greenhouse effect and the throat section 203, which draws in the hot air inside the box 10. At the same time, cold air from the outside enters the cavity 34 through the air inlet 35 on the side wall of the overhead mounting base 31, and forms a relatively stable low-temperature cold source in the cavity 34.

[0030] Example 3: Figures 5 to 7As shown, based on Embodiment 1 and Embodiment 2, a heat exchange assembly 40 is installed between the partition 14 and the side wall of the box 10. The heat exchange assembly 40 is used to automatically adjust the air intake at the bottom of the box 10 under temperature change conditions and realize the linkage control of the air intake area of ​​the box door 11.

[0031] The heat exchange assembly 40 includes positioning shells 41 respectively installed on the opposite surfaces of the partition plate 14 and the housing 10. A rotating shaft 42 is rotatably installed between the opposing positioning shells 41. A bimetallic rotating spring 43 is installed inside the positioning shell 41. The two ends of the bimetallic rotating spring 43 are fixed to the positioning shell 41 and the rotating shaft 42 respectively. When the ambient temperature changes, the bimetallic rotating spring 43 undergoes torsional deformation due to the difference in the thermal expansion coefficients of the two metals, thereby driving the rotating shaft 42 to rotate around its axis.

[0032] The bottom surface of the housing 10 is provided with a sliding groove 15, which extends horizontally. A sliding strip 44 is installed in the sliding groove 15 and can reciprocate along the sliding groove 15. A sliding pin 45 is fixedly installed at one end of the sliding strip 44. A guide groove 421 is provided on the outer circumference of the rotating shaft 42. The guide groove 421 is arranged in a spiral curve. The sliding pin 45 is installed in the guide groove 421. When the rotating shaft 42 rotates under the drive of the bimetallic spring 43, the guide groove 421 converts the rotational motion into the linear reciprocating motion of the sliding strip 44 through the sliding pin 45. A heat exchange plate 46 is fixedly installed at the other end of the sliding strip 44. The heat exchange plate 46 is used to open and close the air inlet at the bottom of the housing 10. In this embodiment, the heat exchange plate 46 is used to open and close the third ventilation slot 111 at the bottom of the housing 10.

[0033] The heat exchange plate 46 includes an internally hollow outer shell 461, which encapsulates a heat exchange medium, preferably paraffin, for absorbing, storing and releasing heat. The outer shell 461 has several arrayed uneven structures 462 on one side of the shell facing the inside of the housing 10 to increase the heat exchange area and improve the thermal response speed.

[0034] Under normal operating conditions where the temperature does not exceed the set threshold, the air inside the chamber 10 flows through the high-pressure chamber, heat exchange chamber and heat collection chamber 201 in sequence by natural convection to achieve basic heat dissipation. At the same time, the heat exchange medium inside the heat exchange plate 46 continuously absorbs and stores some of the heat energy in the air, which plays a role in suppressing temperature fluctuations inside the chamber and slowing down the rate of temperature rise.

[0035] A wind deflector 16 is slidably installed on the inner wall of the door 11 in the vertical direction. The wind deflector 16 has several hollowed-out ventilation holes 161, which are aligned horizontally with the first ventilation slot 110 on the door 11. A wedge block 463 is fixedly installed on the outer shell 461 of the heat exchange plate 46. A special-shaped rod 162 is fixedly installed on one side of the wind deflector 16. A roller 163 is rotatably installed on the special-shaped rod 162. The roller 163 abuts against the guide surface of the wedge block 463. When the heat exchange plate 46 moves horizontally, the wedge block 463 drives the wind deflector 16 to slide in the vertical direction through the roller 163, thereby realizing the linkage opening and closing of the wind deflector 16 and the ventilation slot of the door 11.

[0036] Under low or normal temperature conditions, the bimetallic spring 43 is in its initial state, the heat exchange plate 46 is in the closed position, and the third ventilation slot 111 at the bottom of the box 10 is blocked. At the same time, the hollow ventilation hole 161 on the wind deflector 16 is aligned with the first ventilation slot 110 on the box door 11, so that the box door 11 maintains the basic air intake area. The air inside the box 10 flows through the first ventilation slot 110, the high pressure chamber, the heat exchange chamber and the heat collection chamber 201 by natural convection, so as to achieve basic heat dissipation under low heat load. The heat exchange medium inside the heat exchange plate 46 absorbs and stores part of the heat energy, suppressing the temperature fluctuation inside the box.

[0037] When the high-pressure room ring main unit continues to operate, causing the temperature to rise and reach the set threshold, the bimetallic spring 43 deforms due to heat and drives the rotating shaft 42 to rotate. The guide groove 421 on the rotating shaft 42 pushes the slide bar 44 to move horizontally through the sliding pin 45, so that the heat exchange plate 46 moves from the closed position to the open position, gradually opening the third ventilation slot 111 at the bottom of the box 10. At the same time, the wedge block 463 on the heat exchange plate 46 drives the wind deflector 16 to move vertically downward through the roller 163 and the special rod 162, so that the hollow ventilation hole 161 and the first ventilation slot 110 switch from the aligned state to the misaligned state, reducing the air intake area at the box door 11, forcing more cooling airflow to be introduced from the bottom cavity 34. The low-temperature air in the cavity 34 of the overhead mounting base 31 enters the high-pressure room and heat exchange room first through the third ventilation slot 111, absorbs heat and flows into the heat collection cavity 201, is accelerated through the throat 203 and discharged through the exhaust port 202, forming a strong natural convection heat dissipation path.

[0038] When the temperature inside the chamber drops below the set threshold, the bimetallic spring 43 gradually resets, causing the heat exchange plate 46 and the wind deflector 16 to move in opposite directions. The third ventilation slot 111 closes again, the air intake area of ​​the chamber door 11 is restored, and the system returns to the low heat load operating state, thereby realizing the fully automatic and passive adaptive adjustment of the air intake volume of the chamber 10.

[0039] Working principle: During normal operation, solar radiation heats the heat-absorbing plate 21 inside the heat collection chamber 201 through the glass plate 22. The air inside the chamber is heated and forms a weak thermal pressure, which generates a continuous negative pressure at the lower end of the heat collection chamber 201. This drives the air inside the chamber to flow from bottom to top through the high-pressure chamber and the heat exchange chamber, and finally enters the heat collection chamber 201 and is discharged from the exhaust port 202, forming a stable natural convection micro-circulation. The bimetallic spring 43 is in its initial state, which drives the heat exchange plate 46 to seal the third ventilation slot 111 at the bottom of the chamber 10, cutting off the low-temperature air from the cavity 34 of the overhead base, and preventing unnecessary cold air intrusion that could cause condensation or excessively low temperature.

[0040] The perforated ventilation holes 161 on the windshield grille 16 are aligned with the first ventilation slot 110 on the box door 11 to maintain the initial air intake area. The heat exchange medium inside the heat exchange plate 46 absorbs and stores the short-term heat peak during the day and uses its thermal inertia to smooth the temperature fluctuation inside the box, preventing excessive day-night temperature difference from causing condensation on the surface of the insulation components.

[0041] When the high-pressure room ring main unit continues to operate, causing the temperature to rise and reach the set threshold, the bimetallic spring 43 is heated and twisted, driving the rotating shaft 42 to rotate. The guide groove 421 on the rotating shaft 42 pushes the slide bar 44 to move horizontally through the sliding pin 45, driving the heat exchange plate 46 to open and opening the third ventilation slot 111. The wedge block 463 on the heat exchange plate 46 simultaneously pushes the windproof grille 16 to move vertically downward, so that the hollow ventilation hole 161 and the first ventilation slot 110 change from alignment to misalignment, reducing the air intake area at the box door 11. The low-temperature air in the cavity 34 of the overhead base is strongly drawn into the high-pressure room and the heat exchange room through the third ventilation slot 111 under thermal pressure suction, directly reaching the heat source for efficient cooling. In the heat collection cavity 201, the flow rate of the hot air is significantly increased when it passes through the throat 203, forming a stronger suction force, which discharges the air that has absorbed heat at high speed and washes the ribs 13 under the cantilevered top plate 12, and finally discharges smoothly from the outer edge of the top plate, avoiding heat backflow.

[0042] When the temperature inside the chamber drops below the set threshold, the bimetallic spring 43 gradually resets, the shaft 42 rotates in the opposite direction, and the heat exchange plate 46 re-seals the third ventilation slot 111 through the linkage mechanism. At the same time, the wind deflector 16 resets, restoring the basic air intake area of ​​the chamber door 11, and the device automatically returns to the normal operation mode of heat preservation and basic heat dissipation.
