Description

Technical Field

[0001] The invention relates to the technical field of power monitoring auxiliary equipment, and in particular to an outdoor box-type substation structure. Background Art

[0002] In the prior art, during the operation of outdoor box-type substations, a large amount of heat will be generated due to the thermal effect of the current. If this heat cannot be dissipated in time, the internal temperature of the box-type substation will rise, affecting the working efficiency and service life of the equipment. Outdoor box-type substations are exposed to the environment, and pollutants such as dust, smoke, and mold can easily invade the box, corrode the equipment and damage internal components, and eventually cause equipment short circuits and other faults. Especially in the warm spring days in coastal areas, the air humidity is high, and the equipment is easily corroded in a humid environment for a long time, and condensed water droplets can also cause circuit failures.

[0003] The heat dissipation and dehumidification measures used in existing outdoor box-type substations mainly have the following technical problems: 1. The method of quickly reducing the internal temperature of the box-type substation through compressor refrigeration to maintain a constant humidity around the equipment. Since the refrigeration equipment itself consumes electricity, high-load operation will produce large noise and vibration; the equipment maintenance cost is high, and additional protection measures are required in extreme environments. 2. The method of spraying water mist on the top cover to reduce the external temperature of the box-type substation is easy to affect the surrounding environment and cannot dehumidify. 3. Using forced air cooling and dehumidification, the exhaust fan cannot effectively remove heat and moisture; long-term operation will increase energy consumption and noise, and maintenance costs need to be considered. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an outdoor box-type substation structure, which can effectively remove heat and moisture in the box-type substation; the structure is reasonable, the energy consumption is low, and the equipment maintenance cost is low.

[0005] In order to solve the above technical problems, the present invention provides an outdoor box-type substation structure, comprising: a box-type substation body and a heat dissipation box cover installed on the outside of the box-type substation body, the heat dissipation box cover is composed of a plurality of foldable folding door enclosure top covers, and a shutter is provided at the bottom of the folding door for allowing natural wind to enter; an inclined plate is provided on the inner side of the folding door, a groove is provided on the inclined plate, and a containing box is provided on the inner side of the top cover, wherein: phase change material is provided in the groove and the containing box, wherein: the heat transferred by the external sunlight to the heat dissipation box cover and the heat generated by the box-type substation body itself are absorbed by the phase change material, and the air density at different positions in the heat dissipation box cover changes when the phase change material absorbs heat, and the cold air entering through the multiple shutters forms air convection inside the heat dissipation box cover and is discharged from the top cover.

[0006] Among them, a rotating non-powered hood is installed on the top cover. The phase change material gradually releases heat when the temperature in the heat dissipation box cover decreases, and transfers heat to the outside of the heat dissipation box cover through the rotation of the rotating non-powered hood.

[0007] Among them, the lower temperature air outside is continuously sucked in by the shutters, and the heat released by the phase change material maintains the stability of the temperature inside the radiator cover.

[0008] The cross section of the top cover is ladder-shaped.

[0009] One end of the inclined plate is fastened to the folding door, and the angle formed by the inclined plate and the folding door is in the range of 1°-5°.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 4 The figure shows the first embodiment of the outdoor box-type substation structure of the present invention.

[0021] The outdoor box-type substation structure in this embodiment includes: a box-type substation body 1 and a heat dissipation box cover 2 installed outside the box-type substation body 1, the heat dissipation box cover 2 is composed of a plurality of foldable folding doors 21 enclosing a top cover 22, and a shutter 219 is provided at the bottom of the folding door 21 for allowing natural wind to enter; an inclined plate 3 is provided on the inner side of the folding door 21, a groove is provided on the inclined plate 3, and a receiving box 227 is provided on the inner side of the top cover 2, wherein: a phase change material T is provided in the groove and the receiving box 227.

[0022] Among them: the heat transferred by the external sunlight to the heat dissipation box cover and the heat generated by the operation of the box-type substation body itself are absorbed by the phase change material T, the air density at different positions in the heat dissipation box cover 2 changes when the phase change material absorbs heat, and the cold air entering through multiple shutters 219 forms air convection inside the heat dissipation box cover 2 and is discharged from the top cover 22.

[0023] In other application scenarios, when the external air with a lower temperature is continuously sucked in by the shutter 219, the temperature inside the heat dissipation box cover can also be maintained stable by the heat released by the phase change material.

[0024] In specific implementation, the box-type substation body 1 is in a cubic shape, and the heat dissipation box cover 2 is formed by a plurality of foldable folding doors 21 enclosing a top cover 22, forming a relatively closed accommodation space inside, and the box-type substation body 1 is placed in the accommodation space. The folding door in this embodiment is equipped with a door lock, so that it is convenient to enter the interior of the heat dissipation box cover for equipment maintenance.

[0025] The folding door 21 is in the shape of a plate, and the size of each folding door 21 can be set to be the same or different, as long as a plurality of foldable folding doors 21 are used to enclose the top cover 22 to form a box cover; one end of the inclined plate 3 is fastened to the folding door 21, and the angle between the inclined plate and the folding door is in the range of 1°-5°.

[0026] Furthermore, a shutter 219 is provided at the bottom of the folding door 21 for letting in natural wind; an inclined plate 3 is installed on the inner side of the folding door 21, and a groove is provided on the inclined plate 3. In this embodiment, the shutter 219 is an adjustable vent structure, which can adjust the air flow according to actual needs.

[0027] The inclined plate 3 and the groove are provided to accommodate the phase change material T.

[0028] Furthermore, a rotating non-powered hood 228 is installed on the top cover 22 , and the phase change material T gradually releases heat when the temperature in the heat dissipation box is reduced, and transfers heat to the outside of the heat dissipation box through the rotation of the rotating non-powered hood 228 .

[0029] Preferably, the cross section of the top cover 22 is in a trapezoidal shape. The effect of such a configuration is that the gradually contracting shape is conducive to concentrating the internal airflow to be discharged at the rotating non-powered hood 228 .

[0030] A plurality of accommodating boxes 227 are installed on the inner side of the top cover 2. The accommodating boxes 227 are iron boxes. The function of the accommodating boxes 227 is to place the phase change material.

[0031] The phase change material (PCM) T in this embodiment has the property of absorbing or releasing a large amount of latent heat during the phase change process. The principle of phase change heat storage is that the substance can absorb or release a large amount of latent heat during the transition between the solid phase and the liquid phase. This phase change process makes the phase change material an efficient heat storage medium, and the material can be recycled and the cost is controllable.

[0032] Preferably, the phase change material T in this embodiment is a paraffin-based or inorganic hydrated salt phase change material with a temperature between 25° C. and 30° C., which can absorb a large amount of heat at high temperatures during the day and gradually release it at night.

[0033] Specifically, the paraffin-based phase change material at 25°C can absorb a large amount of heat during the day and gradually release it at night. The inorganic hydrated salt phase change material T at 25°C to 30°C can be used in high-temperature areas, such as extreme high-temperature environments such as deserts. The efficient heat absorption of the phase change material T ensures the normal operation of the box-type transformer equipment.

[0034] In addition, the heat sink cover 2 can also adopt a modular design, supported by a square hollow frame, and a lightweight structural design. The top cover 22 and the folding door 21 can be manually spliced, and the parts are seamlessly connected, which simplifies the installation process and achieves efficient and fast assembly; the economic cost is low, the service life is long, the structure is simple, and the maintenance cost is low.

[0035] At the same time, because the heat dissipation box cover 2 adopts the principle of natural ventilation and phase change material heat storage, it has good applicability for heat dissipation equipment placed outdoors. It can accelerate ventilation and dehumidification when set in an environment with high humidity. The size of the heat dissipation box cover 2 can be adjusted to cover different equipment.

[0036] The daytime working principle of the outdoor box-type substation structure in this embodiment is as follows:

[0037] Natural ventilation and heat dissipation: The shutters 219 installed at the bottom of the folding door 21 ensure that wind from any direction can be received. When the temperature is not high, the flow of natural wind can be used to take away the heat inside the heat dissipation box cover 2 from bottom to top.

[0038] The phase change material T absorbs heat: as the temperature rises, the phase change material T begins to absorb the heat transferred into the heat dissipation box cover 2 by the external sunlight, and also absorbs the heat generated by the heat dissipation box cover 2 itself during operation, ensuring the normal temperature inside the heat dissipation box cover 2.

[0039] Hot air discharge: When the temperature reaches the highest point, the phase change material T absorbs more heat, the air temperature at the top of the heat dissipation box cover 2 is higher, and the air temperature at the lower louver 219 is lower. The temperature difference causes the air density to change. The upper hot air has a low density and is discharged from the top rotating non-powered hood 228; the lower cold air enters from the louver 219, forming air convection Y to accelerate heat dissipation.

[0040] The nighttime working principle of the outdoor box-type substation structure in this embodiment is as follows:

[0041] The phase change material T releases heat: the air temperature decreases at night, and the heat absorbed by the phase change material T during the day is gradually released. The air temperature above the heat dissipation box cover 2 is still higher than that below, and the hot air continues to drive the rotary non-powered hood 228 to rotate.

[0042] Continuous ventilation and heat dissipation: air with lower outside temperature is sucked in from the shutters 219 to cool the phase change; the heat released by the phase change material T maintains the temperature inside the heat dissipation box cover 2 stable, preventing the box-type substation body 1 from being damaged due to excessive temperature difference.

[0043] In this embodiment, the principle of dehumidification of the outdoor box-type substation structure on warm days is as follows:

[0044] Heating the air: The heat absorbed by the phase change material T during the day can heat the air in the heat dissipation box cover 2, increase the saturated water vapor pressure of the air, and reduce the generation of water droplets.

[0045] Accelerate air flow: The heated air is heated, which accelerates the flow of gas in the heat dissipation box cover 2. The shutters 219 continuously inhale external cold air, which is discharged from the rotating non-powered hood 228 of the top cover 22 after heating, reducing the retention of water vapor in the equipment space, keeping the equipment dry, and improving the humidity problem of the outdoor box.

[0046] In addition, the outdoor box-type substation structure in this embodiment is easy to install and transport, and is suitable for efficient and fast assembly. Under all-weather temperature changes, the heat dissipation box cover 2 can provide corresponding ventilation, heat absorption, cooling, and dehumidification methods, effectively ensuring that the heat emitted by the box-type substation can be taken away in time for a long time, and ensuring that the environmental humidity does not affect the normal operation of the equipment.
