Abstract
Description
Technical Field
[0001] This invention relates to the field of ring network box technology, specifically a modular primary and secondary integrated column-mounted ring network box. Background Technology
[0002] As a key node device in the power distribution network system, the ring main unit undertakes important functions of power distribution, protection and control, and is widely used in urban power grids, industrial parks and outdoor power distribution lines. With the advancement of smart grid construction and the improvement of power distribution automation, traditional ring main units have gradually revealed many limitations in terms of structural design, heat dissipation performance, environmental adaptability and operation and maintenance convenience.
[0003] In terms of heat dissipation, traditional ring main units mostly rely on natural air cooling or forced convection cooling by adding fans. Natural air cooling has limited efficiency and is difficult to cope with the instantaneous temperature rise during high-load operation. Fan cooling, on the other hand, has problems such as high energy consumption, loud noise, and easy dust accumulation and damage. Especially in dusty and humid outdoor environments, ventilation holes are easily blocked by dust, catkins and other debris, resulting in a sharp decline in heat dissipation efficiency. Internal equipment will age faster or even fail due to long-term overheating. In addition, conventional heat dissipation structures lack temperature self-adaptive adjustment capabilities and cannot dynamically adjust the heat dissipation intensity according to changes in internal temperature, which restricts the reliability and energy efficiency of equipment operation.
[0004] In terms of structural design, traditional ring main units mostly adopt an integral or non-modular layout, lacking effective functional integration and physical isolation between primary and secondary equipment; the mixed arrangement of primary equipment (such as circuit breakers and load switches) and secondary equipment (such as measurement and control devices and communication modules) not only increases the risk of electromagnetic interference, but also brings inconvenience to equipment maintenance and replacement; at the same time, the internal space utilization efficiency of the enclosure is low, the expandability is poor, and it is difficult to meet the needs of future power distribution system upgrades and renovations.
[0005] For example, the Chinese invention patent (application number: CN202311040008.6) discloses "a ring main unit," whose specification states that a ring main unit is a device used in power distribution systems, typically installed between distribution transformers and distribution cabinets. It is used for tapping, distributing, and protecting power systems, primarily for controlling and distributing current. Ring main units are commonly used in urban power grids, industrial power supply, and large buildings. Ring main units can control and regulate the power system through control switches and protection devices, improving the stability and reliability of the power system. In short, ring main units are indispensable power distribution equipment in power systems, enabling the distribution, regulation, protection, and control of electrical energy, ensuring the normal operation and safe use of the power system. During use, the equipment inside the ring main unit continuously releases heat, increasing the internal temperature. To prevent damage to the equipment, heat dissipation is necessary. However, as the cooling time increases, the ventilation holes gradually become clogged with dust, reducing the cooling effect and potentially causing equipment damage.

[0011] As a preferred technical solution of this application, the filling layer is provided with symmetrical inner grooves, and the filling layer is symmetrically fitted with heat-conducting fins through the inner grooves, and the heat-conducting fins are bent.
[0012] As a preferred technical solution of this application, a base plate is fixedly installed on the bottom of the inner side of the temperature-conducting ring plate, and the bottom of the base plate, the first side plate and the second side plate are symmetrically provided with sliding grooves.
[0013] As a preferred technical solution of this application, the adjustment component includes fixed shafts symmetrically distributed at the upper and lower ends of the partition. One end of the fixed shaft is fixedly connected to the inner side of the box body opposite to the box door.

A right-angle shaft is slidably sleeved on the connecting block through the sleeve groove. One end of the right-angle shaft is fixedly connected to the inner side of the box.
[0015] As a preferred technical solution of this application, an upwardly inclined conduction shaft is provided at intervals below the connecting block, and a pull rope connected to the bottom of the connecting block is fixedly installed on the bottom of the outer side of the conduction shaft. A connecting plate is rotatably sleeved on the other end of the conduction shaft, and the connecting plate is fixedly connected to the inner side of the temperature conducting component. A round shaft is rotatably sleeved on the lower middle part of the outer side of the conduction shaft, and the round shaft is fixedly connected to the inner side of the box.
[0016] As a preferred technical solution of this application, an installation block is fixedly installed on the outer side of the fixed shaft, and a telescopic shaft is fixedly installed on the outer side of the installation block.

[0018] As a preferred technical solution of this application, a connecting seat is arranged on the side of the box away from the box door, and a connecting rod is spherically connected to the box via the connecting seat. A clamp is fixedly installed on the other side of the connecting rod, and a buckle is provided on the outer side of the clamp opposite to the connecting rod.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] 1. By utilizing the latent heat of phase change of the paraffin-filled layer in the temperature-conducting component, a large amount of heat is actively absorbed and stored when the equipment heats up, effectively buffering the rate of temperature rise; when the temperature rises further, the bimetallic strip in the regulating component deforms due to heat, and drives the temperature-conducting component to move along the slide rail towards the ventilation opening through transmission mechanisms such as the conduction shaft and pull rope, significantly enhancing the heat dissipation area and efficiency.
[0021] 2. The internal cavity of the enclosure is divided into sections by partitions, achieving physical isolation and functional integration of primary and secondary equipment. This reduces electromagnetic interference and facilitates independent maintenance and module replacement.

[0023] 4. The reliability and longevity of the heat dissipation structure have been optimized. The heat-conducting fins are embedded in the paraffin-filled layer, increasing the heat conduction area; the bimetallic strip is made of Invar steel and manganese nickel copper steel composite material, ensuring the sensitivity and durability of thermal response; the telescopic shaft and the return spring form a buffer reset mechanism, enabling the system to be used repeatedly.

[0037] 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.
[0038] This invention provides a technical solution: such as Figure 1 - Figure 8 The modular primary and secondary fusion column-mounted ring mesh box shown includes a box body 1. A partition 10 is fixedly installed in the middle of the inner cavity of the box body 1. Temperature conducting components 8 that transfer heat through latent heat of phase change are symmetrically arranged on the left and right sides of the partition 10. The temperature conducting components 8 include temperature conducting ring plates 801 spaced apart on the left and right sides of the partition 10. The interior of the temperature conducting ring plates 801 is filled with a filling layer 805, and the filling layer 805 is made of paraffin wax. Adjustment components 9 that change the position of the temperature conducting components 8 by thermal deformation are symmetrically installed at the upper and lower ends of the partition 10. A box door 2 is provided on one side of the box body 1. A heat insulation chamber 11 is fixedly installed on the inner side of the box door 2. Heat insulation cotton 12 is fixedly installed on the side of the heat insulation chamber 11 closest to the box body 1.
[0039] Through the latent heat of phase change of the paraffin-filled layer 805 in the temperature-conducting component 8, a large amount of heat is actively absorbed and stored when the equipment is heated, effectively buffering the rate of temperature rise; when the temperature rises further, the bimetallic strip 902 in the regulating component 9 is deformed by heat, and the temperature-conducting component 8 is driven to move along the slide rail 13 toward the ventilation port 7 through the transmission mechanism such as the conduction shaft 907 and the pull rope 909, which significantly enhances the heat dissipation area and efficiency.
[0040] like Figure 7 and Figure 8 As shown, the temperature-conducting assembly 8 also includes first side plates 803 symmetrically installed on the left and right sides of the temperature-conducting ring plate 801. Four sets of corners of the first side plate 803 have pre-set circular grooves. A second side plate 804 is fixedly installed on the outer side of the first side plate 803. A gap is pre-set between the first side plate 803 and the second side plate 804. During use, the temperature-conducting ring plate 801 is sealed by the first side plate 803 and the second side plate 804. As the equipment continues to operate, the temperature inside the housing 1 continuously rises. At this time, the symmetrically installed heat-conducting fins 802 inside the temperature-conducting ring plate 801, and the first side plate 803 and the second side plate 804 installed on one side of each side of the ring plate 801, provide insulation. 04. Heat is transferred to the filling layer 805, where paraffin wax absorbs the heat. The specific heat capacity of paraffin wax slows down the temperature rise inside the chamber. When the outside temperature suddenly drops, the paraffin wax can release heat to form a barrier, thus preventing the rapid drop in outside temperature from combining with the high temperature inside the chamber, which would cause condensation on the outer wall of the chamber 1 and affect the use of the overall device. The first side plate 803 and the second side plate 804 are designed to store the hot steam when the paraffin wax temperature rises and evaporates under special circumstances, preventing the hot steam from expanding and breaking the entire temperature-conducting component 8, and thus corroding the components inside the chamber 1.
[0041] Furthermore, the filling layer 805 has symmetrically formed inner grooves 808 inside, and the filling layer 805 is symmetrically fitted with heat-conducting fins 802 through the inner grooves 808, and the heat-conducting fins 802 are bent.
[0042] Furthermore, a base plate 806 is fixedly installed on the bottom of the inner side of the temperature-conducting ring plate 801. The bottom of the base plate 806, the first side plate 803 and the second side plate 804 are symmetrically provided with sliding grooves 807. The bottom of the temperature-conducting ring plate 801 is sealed by the base plate 806. At the same time, with the cooperation of the slide rail 13, the entire temperature-conducting assembly 8 can be slid easily.
[0043] like Figure 6As shown, the adjustment component 9 includes fixed shafts 901 symmetrically distributed at the upper and lower ends of the partition 10. One end of the fixed shaft 901 is fixedly connected to the inner side of the box 1 opposite to the box door 2. Both ends of the outer side of the fixed shaft 901 are equipped with bimetallic strips 902 in the shape of torsion springs. The outer layer of the bimetallic strip 902 is made of Invar steel, and the inner layer of the bimetallic strip 902 is made of manganese nickel copper steel. By installing the bimetallic strip 902 through the fixed shaft 901, the bimetallic strip 902 can be made to shrink when heated.
[0044] Furthermore, an extension piece 903 is fixedly installed at the other end of the bimetallic strip 902. One end of the extension piece 903 is circular, and a connecting block 904 is sleeved on the other end of the extension piece 903. The connecting block 904 is n-shaped, and a sleeve groove 906 is formed through the side wall of the connecting block 904. A right-angle shaft 905 is slidably sleeved on the connecting block 904 through the sleeve groove 906. One end of the right-angle shaft 905 is fixedly connected to the inner side of the box body 1. In use, it can be adjusted according to the installation method of the box door 2. For different installations of the right-angle shaft 905, when the door 2 and the body 1 are hinged, you can choose to remove the bimetallic strip 902 near the end of the fixed shaft 901 near the door 2, or directly press the connecting block 904 and the right-angle shaft 905 on this side into contact with the insulation cotton 12. If you choose to install by snap-fit, you can fix the connecting block 904 and the right-angle shaft 905 to the insulation chamber 11. At this time, you can snap-fit the bimetallic strip 902 on the side of the door 2 to the outside of the fixed shaft 901.
[0045] Furthermore, an upwardly inclined conduction shaft 907 is spaced apart below the connecting block 904. A pull rope 909 connected to the bottom of the connecting block 904 is fixedly installed on the bottom of the outer side of the conduction shaft 907. A connecting plate 910 is rotatably sleeved on the other end of the conduction shaft 907, and the connecting plate 910 is fixedly connected to the inner side of the temperature conducting component 8. A round shaft 908 is rotatably sleeved on the lower middle part of the outer side of the conduction shaft 907, and the round shaft 908 is fixedly connected to the inner side of the box 1. The bimetallic strip 902 shrinks when heated, causing it to drive the connecting block 904 to slide along the right-angle axis 905. Combined with the pull rope 909 pulling the conduction shaft 907 to rotate around the round shaft 908, it pushes the temperature conducting component 8 to move outward. Then, according to the temperature inside the box 1, the gap between the temperature conducting components 8 is automatically adjusted to provide more space for unabsorbed heat and allow it to wait for absorption.
[0046] Furthermore, a mounting block 913 is fixedly installed on the outer side of the fixed shaft 901, and a telescopic shaft 911 is fixedly installed on the outer side of the mounting block 913. The other end of the telescopic shaft 911 is connected to the side wall of the temperature-conducting component 8. A return spring 912 is fixedly sleeved on the outer side of the telescopic shaft 911. The return spring 912, together with the telescopic shaft 911 and the slide rail 13, facilitates the reset of the temperature-conducting component 8.
[0047] like Figure 1 and Figure 2 As shown, slide rails 13 are symmetrically installed on the bottom of the inner side of the box 1, and the slide rails 13 match the bottom of the temperature conducting component 8. Ventilation openings 7 are evenly distributed on both sides of the box 1.
[0048] Furthermore, a connecting seat 6 is arranged on the side of the box body 1 away from the box door 2. The box body 1 is spherically connected to a connecting rod 5 through the connecting seat 6. A clamp 3 is fixedly installed on the other side of the connecting rod 5. A latch 4 is provided on the outer side of the clamp 3 opposite to the connecting rod 5. The clamp 3 and the latch 4 make it easy to wrap the box body 1 around the outside of the column. The connecting rod 5 and the connecting seat 6 make it easy to rotate the clamp 3, thus facilitating disassembly and assembly.
[0049] Working principle: As the temperature inside the chamber gradually rises due to continuous operation of the equipment, heat is first transferred to the temperature-conducting component 8 and the regulating component 9 through air convection and thermal radiation. The temperature-conducting component 8 is symmetrically arranged on the left and right sides of the partition 10 in the middle of the chamber 1. Its temperature-conducting ring plate 801 is filled with a filling layer 805 made of paraffin wax. As a highly efficient phase change material, paraffin wax changes from solid to liquid when heated to the phase change temperature. In this process, it absorbs and stores a large amount of latent heat of phase change, thereby effectively slowing down the rapid rise of the temperature inside the chamber and playing a preliminary role in temperature buffering and stabilization. To further improve thermal management efficiency, the filling layer 805 is further... Bent heat-conducting fins 802 are fitted into the symmetrically opened inner grooves 808. These fins significantly increase the heat exchange area and can quickly conduct the heat generated by the equipment to the paraffin filling layer 805, accelerating the phase change process. At the same time, the first side plate 803 and the second side plate 804 installed on the left and right sides of the temperature-conducting ring plate 801 further expand the heat dissipation surface area and together with the bottom plate 806, they form a stable heat-conducting structure. The sliding groove 807 opened at the bottom of this structure matches the sliding rail 13 symmetrically installed on the bottom of the inner side of the housing 1, providing physical guidance and sliding basis for the subsequent component displacement caused by temperature changes.
[0050] As the internal temperature continues to rise and exceeds a certain threshold, heat is transferred to the regulating component 9. The regulating component 9 is symmetrically distributed at the upper and lower ends of the partition 10. The bimetallic strip 902, located on its inner side, uses Invar steel as the outer layer and manganese-nickel-copper steel as the inner layer. Utilizing the significant difference in the thermal expansion coefficients of the two metals, it undergoes directional bending deformation when heated, thereby releasing torsional driving force. The deformation of the bimetallic strip 902 causes displacement of the extension piece 903 fixedly mounted at its end. The extension piece 903 is then connected to the connecting block 904 via a circular structure at one end. The connecting block 904 is n-shaped, and its sidewall has a slot 906 that allows it to slide along a right-angle axis 905 fixed to the housing 1. The displacement of the connecting block 904 is transmitted to the conductive shaft 907 via the pull rope 909 connected to its bottom. The traction force of the pull rope 909 causes the upwardly inclined conductive shaft 907 to rotate around the circular shaft 908 sleeved in its lower part. The other end of the conductive shaft 907 is fixedly connected to the inner side of the temperature-conducting assembly 8 via the connecting plate 910. Therefore, the rotation of the conductive shaft 907 is ultimately converted into position control of the entire temperature-conducting assembly 8, driving it to move along the bottom slide rail 13 towards the vent 7 on the side wall of the housing 1. During this process, the telescopic shaft 911 fixed to the outside of the fixed shaft 901 via the mounting block 913 and the return spring 912 sleeved on its outside provide necessary buffering and reverse return elastic force for the movement of the temperature-conducting assembly 8. This ensures the smoothness and reversibility of component movement; the change in position of the temperature-conducting component 8 allows it to be more directly exposed to the air convection environment formed by the evenly distributed ventilation openings 7 on both sides of the housing 1, greatly enhancing the heat exchange efficiency between the inside and outside of the housing, thereby achieving efficient active heat dissipation; when the equipment inside the housing stops working or the load decreases, causing the temperature to drop, the bimetallic strip 902 cools down and gradually returns to its initial shape, and its torsional force weakens; at this time, under the contraction action of the return spring 912, the telescopic shaft 911 retracts and pulls the temperature-conducting component 8 along the slide rail 13 back to its initial position through the connecting mechanism, preparing for the next thermal management cycle; at the same time, the paraffin filling layer 805 releases liquid during the temperature drop. The latent heat is released and solidified back to a solid state, completing a full heat absorption and release cycle. In addition, the heat insulation chamber 11 set inside the door 2 on one side of the enclosure 1 and the heat insulation cotton 12 installed near the side of the enclosure 1 effectively block the influence of external environmental temperature fluctuations on the equipment inside the enclosure, improving the environmental stability of the equipment operation. The enclosure 1, through the connecting seats 6 arranged in an array on its back, the ball-shaped connecting rod 5, the clamp 3 and the locking buckle 4 structure, realizes flexible and stable installation on columnar objects such as utility poles, adapting to a variety of complex outdoor installation scenarios. The entire system, through the phase change heat storage of the temperature conducting component 8 and the thermal deformation drive of the regulating component 9, collaboratively realizes passive, adaptive, efficient and reliable intelligent control of the internal temperature of the ring network enclosure.
