Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a container transformer. Background Art
[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. Components such as transformers, high-voltage cabinets, and control devices need to be installed in the container transformer. During the use of the container transformer, when the outside temperature is too high, the heat inside the container transformer cannot be discharged in a timely and effective manner, which will cause the internal temperature of the container transformer to be too high, thereby reducing the service life of the components. When the outside environment is humid, the air humidity is high, and there is a possibility of condensation inside the container transformer, which will affect the insulation performance of the container transformer and even cause a short circuit. In view of the above situation, the general solution is to install an external high-power fan on the container transformer to dissipate heat, but the condensation problem inside the container transformer cannot be effectively eliminated.
[0003] In response to the above problems, some people have proposed to install temperature sensors, humidity sensors, heaters and heat exchangers in the container transformer, monitor the temperature and humidity in the container transformer through the temperature sensors and humidity sensors, and work through the heater and heat exchanger when the temperature and humidity exceed the set thresholds to ensure that the temperature and humidity in the container transformer are within the set thresholds. Although this container transformer structure solves the above problems to a certain extent, the installation position of the heat exchanger is at the top of the container transformer, resulting in poor cooling effect, and adding a heater to remove condensation increases the design cost.

[0034] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0035] like Figure 1-Figure 5As shown, an embodiment of the utility model provides a container transformer, which includes a box body 1, and the box body 1 includes a high-pressure chamber 11 and a low-pressure chamber 12. A first heat exchanger 1111 is provided at the upper and lower parts of the high-pressure chamber 11 along the vertical direction (i.e., the height direction of the box body 1), and a second heat exchanger 1211 is provided at the upper and lower parts of the low-pressure chamber 12 along the vertical direction. The first heat exchanger 1111 and the second heat exchanger 1211 can discharge the heat in the high-pressure chamber 11 and the low-pressure chamber 12 out of the container transformer to cool down the container transformer, and the first heat exchanger 1111 and the second heat exchanger 1211 can also generate hot air to increase the temperature in the high-pressure chamber 11 and the low-pressure chamber 12 to dehumidify the container transformer.
[0036] A first temperature sensor 2 and a first humidity sensor 4 are also provided in the high-pressure chamber 11, and the first temperature sensor 2 and the first humidity sensor 4 are both communicatively connected to the first heat exchanger 1111. A second temperature sensor 3 and a second humidity sensor are also provided in the low-pressure chamber 12, and the second temperature sensor 3 and the second humidity sensor are communicatively connected to the second heat exchanger 1211.
[0037] When the first temperature sensor 2 detects that the temperature of the high-pressure chamber 11 and the second temperature sensor 3 detects that the temperature in the low-pressure chamber 12 exceeds a certain temperature, the first heat exchanger 1111 and the second heat exchanger 1211 located at the upper part of the high-pressure chamber 11 and the low-pressure chamber 12 are started, and the heat in the high-pressure chamber 11 and the low-pressure chamber 12 is discharged for heat exchange to cool down the high-pressure chamber 11 and the low-pressure chamber 12. It should be noted that according to the principle of hot air flow, the hot air will flow upward, and opening the first heat exchanger 1111 and the second heat exchanger 1211 located at the upper part of the high-pressure chamber 11 and the low-pressure chamber 12 can respectively quickly discharge the heat in the high-pressure chamber 11 and the low-pressure chamber 12, thereby improving the heat exchange efficiency.
[0038] When the first humidity sensor 4 detects that the humidity in the high-pressure chamber 11 and the second humidity sensor detects that the humidity in the low-pressure chamber 12 exceeds a certain humidity, the first heat exchanger 1111 and the second heat exchanger 1211 located at the lower part of the high-pressure chamber 11 and the low-pressure chamber 12 are started to generate hot air, and the hot air enters from the lower part of the high-pressure chamber 11 and the low-pressure chamber 12 respectively, and flows to the upper part, which can quickly increase the temperature in the high-pressure chamber 11 and the low-pressure chamber 12, so as to quickly remove the condensation in the high-pressure chamber 11 and the low-pressure chamber 12, thereby achieving the problem of reducing the humidity in the high-pressure chamber 11 and the low-pressure chamber 12. It should be noted that since the lower part of the high-pressure chamber 11 and the low-pressure chamber 12 is the position where condensation is most likely to occur, when dehumidification is required, the first heat exchanger 1111 and the second heat exchanger 1211 located at the lower part of the high-pressure chamber 11 and the low-pressure chamber 12 are turned on to achieve rapid dehumidification.
[0039] The container transformer chooses to open the first heat exchanger 1111 and the second heat exchanger 1211 at different positions for temperature regulation and humidity regulation, so as to achieve rapid cooling and rapid removal of condensation, thereby improving efficiency; and the first heat exchanger 1111 is arranged inside the high-pressure chamber 11, and the second heat exchanger 1211 is arranged inside the low-pressure chamber 12, thereby reducing the overall volume.
[0040] The box body 1 also includes a transformer room 13 arranged between the high-voltage chamber 11 and the low-voltage chamber 12. A high-voltage cabinet 112 is arranged in the high-voltage chamber 11. A control device 122 is arranged on one side wall of the low-voltage chamber 12. The control device 122 is communicatively connected with the first heat exchanger 1111, the second heat exchanger 1211, the first temperature sensor 2, the second temperature sensor 3, the first humidity sensor 4 and the second humidity sensor. After the first temperature sensor 2 and the second temperature sensor 3 receive a signal that the temperature exceeds a certain temperature, the control device 122 can control the first heat exchanger 1111 and the second heat exchanger 121 at the upper part of the high-voltage chamber 11 and the low-voltage chamber 12. 1 is started, and after the temperature in the high-pressure chamber 11 and the low-pressure chamber 12 reaches the requirement, the control device 122 controls the first heat exchanger 1111 and the second heat exchanger 1211 in the upper part to stop; after the first humidity sensor 4 and the second humidity sensor receive the humidity exceeding a certain humidity, the control device 122 can control the first heat exchanger 1111 and the second heat exchanger 1211 in the lower part of the high-pressure chamber 11 and the low-pressure chamber 12 to start, and after the humidity in the high-pressure chamber 11 and the low-pressure chamber 12 reaches the requirement, the control device 122 controls the first heat exchanger 1111 and the second heat exchanger 1211 in the lower part to stop; a transformer is arranged in the transformer chamber 13. In this structure, the control device 122 is arranged in the low-pressure chamber 12, and the layout of components is more reasonable.
[0041] Furthermore, if Figure 1-Figure 2 As shown, a first cabinet door 111 is provided on the side of the high-voltage chamber 11 facing away from the transformer chamber 13, and a first heat exchanger 1111 is provided on the upper part (i.e., the upper edge position of the high-voltage chamber 11 near its top surface) and the lower part (i.e., the lower edge position of the high-voltage chamber 11 near its bottom surface) of the first cabinet door 111 in the vertical direction; a second cabinet door 121 is provided on the side of the low-voltage chamber 12 facing away from the transformer chamber 13, and a second heat exchanger 1211 is provided on the upper part (i.e., the upper edge position of the low-voltage chamber 12 near its top surface) and the lower part (i.e., the lower edge position of the low-voltage chamber 12 near its bottom surface) of the second cabinet door 121 in the vertical direction. By installing the first heat exchanger 1111 on the first cabinet door 111 of the high-pressure chamber 11 and installing the second heat exchanger 1211 on the second cabinet door 121 of the low-pressure chamber 12, the first heat exchanger 1111 and the second heat exchanger 1211 are installed and arranged reasonably without occupying the space in the high-pressure chamber 11 and the low-pressure chamber 12.
[0042] The first cabinet door 111 includes two first door panels that open opposite each other, and first heat exchangers 1111 are provided at the upper and lower parts of the two first door panels in the vertical direction. By providing the first heat exchangers 1111 at the upper and lower parts of the two first cabinet doors 111, the cooling and dehumidification efficiency in the high-pressure chamber 11 can be effectively improved.
[0043] The second cabinet door 121 includes two second door panels, and second heat exchangers 1211 are provided at the upper and lower parts of the two second door panels in the vertical direction. By providing the second heat exchangers 1211 at the upper and lower parts of the two second cabinet doors 121, the cooling and dehumidification efficiency in the low-pressure chamber 12 can be effectively improved.
[0044] Of course, in other embodiments, the first cabinet door 111 may include only one first door panel, and the second cabinet door 121 may include only one second door panel.
[0045] Furthermore, the first humidity sensor 4 is arranged on the inner side of the first cabinet door 111, and the second humidity sensor is arranged on the inner side of the second cabinet door 121, so that the structural layout is more reasonable.
[0046] In order to more accurately grasp the humidity changes in the high-pressure chamber 11 and the low-pressure chamber 12, refer to Figure 5 As shown, the first humidity sensor 4 is arranged at the lower edge of the inner side surface of the first cabinet door 111 in the vertical direction; the second humidity sensor is arranged at the lower edge of the inner side surface of the second cabinet door 121 in the vertical direction. It should be noted that the lower edge of the first cabinet door 111 on the high-pressure chamber 11 and the lower edge of the second cabinet door 121 in the low-pressure chamber 12 are the positions with the lowest temperature in the high-pressure chamber 11 and the low-pressure chamber 12, that is, the positions with the largest temperature difference. The positions with the largest temperature difference in the high-pressure chamber 11 and the low-pressure chamber 12 are most likely to produce condensation.
[0047] Furthermore, the first humidity sensor 4 is arranged on any one of the two first door panels, and is close to the joint gap between the two first door panels when they are closed; the second humidity sensor is arranged on any one of the two second door panels, and is close to the joint gap between the two second door panels when they are closed. This structure makes the position setting of the first humidity sensor 4 and the second humidity sensor more reasonable, and the detection is more accurate.
[0048] In order to more intuitively and quickly grasp the temperature changes in the high pressure chamber 11 and the low pressure chamber 12, refer to Figure 3 As shown, the first temperature sensor 2 in the high-voltage chamber 11 is arranged on the high-voltage cabinet 112 and close to the location where the high-voltage cabinet 112 generates more heat; Figure 4As shown, the second temperature sensor 3 in the low-pressure chamber 12 is arranged on a side wall surface in the low-pressure chamber 12 and close to the control device 122, and the control device 122 is a position where the heat is relatively high in the low-pressure chamber 12. By respectively arranging the first temperature sensor 2 and the second temperature sensor 3 at positions where the temperature is relatively high in the high-pressure chamber 11 and the low-pressure chamber 12, the control is more accurate and the detection is more intuitive.
[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
