DETAILED DESCRIPTION
[0021] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model is described in detail below in conjunction with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.
[0022] As Figure 1 As shown, it is a kind of photovoltaic power station box transformer with sunshade device of the utility model, it mainly includes the box 4 of high pressure chamber 1, low pressure chamber 2 and transformer room 3 and the first heat dissipation port 5 opened in high pressure chamber 1, low pressure chamber 2 and transformer room 3 cabinet door, when using, open the first heat dissipation port 5, so that the natural wind of outside enters the inside of box 4, the heat in the inside of box 4 is discharged, realizes the circulation of box 4 and outside airflow, above is the introduction of a kind of photovoltaic power station box transformer with sunshade device of the existing.
[0023] From the above, it is known that the photovoltaic power station box transformer with sunshade device of the existing in use, there are following defects, traditional box transformer design often only focuses on basic power conversion function, and ignores the comprehensive consideration of sunshade and heat dissipation, leading to under long time sunshine, the temperature in the inside of box transformer is too high, influence equipment performance and life.At the same time, traditional heat dissipation design often lacks intelligent control, cannot automatically adjust the opening and closing of heat dissipation port according to weather and environmental conditions, which not only affects the heat dissipation effect, but also may cause internal equipment damage due to rain and snow and other bad weather, based on the above problems, the utility model uses the following improvement mode to solve.
[0024] As Figures 2-7As shown, a box transformer for photovoltaic power station with sunshade device, comprising a box body 4 composed of high-voltage chamber 1, low-voltage chamber 2 and transformer chamber 3, and first heat dissipation port 5 opened on the cabinet door of high-voltage chamber 1, low-voltage chamber 2 and transformer chamber 3, on the basis of the above prior art, further comprising solar photovoltaic panel 7 installed above the box body 4 through support frame 6 and second heat dissipation port 8 opened on the top wall of high-voltage chamber 1, low-voltage chamber 2 and transformer chamber 3, the box body 4 is provided with shutter assembly 9 for controlling the opening and closing of first heat dissipation port 5 and second heat dissipation port 8, which integrates sunshade device (solar photovoltaic panel 7) and heat dissipation design (first, second heat dissipation port 8 and shutter assembly 9), effectively improving the energy efficiency of photovoltaic power station box transformer; The installation of solar photovoltaic panel 7 not only provides necessary sunshade for the box transformer, but also realizes the utilization of green energy and reduces the dependence on traditional energy; The setting of first heat dissipation port 5 and second heat dissipation port 8, combined with the regulation and control of shutter assembly 9, ensures the heat dissipation demand of box transformer under different environments, improves its operation stability and service life.
[0025] Further, as shown in Figures 1-2 In order to intelligently control the opening and closing of first heat dissipation port 5 and second heat dissipation port 8, on the basis of the above, rain and snow sensor 10 is added, the controller controls shutter assembly 9 according to the weather information detected by rain and snow sensor 10 in real time, avoiding the damage to the internal equipment of box transformer caused by rain and snow and other bad weather.
[0026] Further, as shown in Figures 5-6 On the basis of the above, the shutter assembly 9 is subdivided into first shutter assembly 11 for controlling the opening and closing of first heat dissipation port 5 and second shutter assembly 12 for controlling the opening and closing of second heat dissipation port 8, which can accurately adjust the opening and closing state of first heat dissipation port 5 and second heat dissipation port 8 according to the weather information, when it is necessary to adjust first heat dissipation port 5 or second heat dissipation port 8, the controller controls the movement of electric telescopic rod 15, drives shielding plate 14 to slide along slide rail 13, realizes the opening or closing of first heat dissipation port 5, when rain and snow sensor 10 detects snowfall signal, the signal is transmitted to the controller, the controller controls the movement of electric telescopic rod 15 in first shutter assembly 11 by a proper distance (i.e. the same distance as the length of first heat dissipation port 8), drives shielding plate 14 to slide towards first heat dissipation port 5, until the end of shielding plate 14 touches the end of slide rail 13, realizes the closing of first heat dissipation port 5, at the same time, the controller controls the movement of electric telescopic rod 15 in second shutter assembly 12, drives shielding plate 14 to slide away from second heat dissipation port 8 by a proper distance (i.e. the same distance as the length of second heat dissipation port 8), realizes the opening of second heat dissipation port 8, the hot air discharged from second heat dissipation port 8 can melt the snow on solar photovoltaic panel 7, reducing the pressure on solar photovoltaic panel 7, in rainy days or non-rainy weather state, first heat dissipation port 5 is in the open state, while second heat dissipation port 8 is in the closed state.
[0027] Furthermore, such as Figures 2-7 As shown, on rainy or snowy days, the humidity increases, and a large amount of moisture enters the enclosure 4 through the heat dissipation vents, which can damage the equipment inside. The addition of a humidity sensor allows the transformer to intelligently adjust the opening and closing of the heat dissipation vents according to changes in ambient humidity, preventing equipment damage or performance degradation due to excessive humidity. The humidity sensor is connected to the controller. If the rain / snow sensor 10 detects that it is raining and the humidity detected by the humidity sensor is higher than a preset threshold, the controller controls the electric telescopic rod 15 in the first gate assembly 11 to move an appropriate distance (one-third of the length of the first heat dissipation vent 5) away from the first heat dissipation vent 5. The controller controls the electric telescopic rod 15 in the second gate assembly 12 to move an appropriate distance (half the length of the second heat dissipation vent 8) away from the second heat dissipation vent 8, so that the second heat dissipation vent 8 is in a semi-closed state. This ensures heat dissipation while reducing the entry of moisture. For example, when the rain and snow sensor 10 detects that it is snowing and the humidity sensor detects that the humidity is higher than the preset threshold, the controller controls the electric telescopic rod 15 in the second gate assembly 12 to move an appropriate distance away from the second heat dissipation vent 8, so that the second heat dissipation vent 8 is in a semi-closed state. Under certain circumstances, the size of the first heat dissipation vent 5 or the second heat dissipation vent 8 can also be intelligently adjusted according to the humidity value of the weather. That is, when the humidity is higher, the gap of the first heat dissipation vent 5 or the second heat dissipation vent 8 is smaller.
[0028] Furthermore, such as Figure 7 As shown, installing a fan 16 inside the transformer room 3 can increase the speed of heat dissipation inside the transformer room 3. In rainy or snowy weather, the fan 16 in the high-voltage room 1 can be stopped in time through the intelligent control of the controller, avoiding the problem of rain and snow intrusion caused by the operation of the fan 16. This design further enhances the adaptability of the transformer to severe weather and ensures its long-term and stable operation.
