[0002] The internal ambient temperature of a box-type substation (hereinafter referred to as a box-type substation) has a very important impact on the working performance of the transformer and high and low voltage cabinets. Therefore, fans or air conditioners and other heat dissipation equipment are installed inside the box-type substation to reduce the temperature.

[0003] Currently, cooling solutions for box-type transformers typically estimate the heat dissipation of components such as the transformer within the box-type transformer to design the number of fans and circulating air volume. This is followed by a set of cooling devices for convection cooling of the box-type transformer. To meet the cooling requirements of the box-type transformer's maximum load, a large design margin is typically used. However, components within the box-type transformer typically do not always operate at maximum load, which inevitably increases energy consumption. Utility Model Content

[0046] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are provided herein to explain the present invention, but are not intended to limit the present invention. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application may be combined with each other in any manner.

[0047] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or apparatuses.

[0048] In order to facilitate understanding of the technical solution provided by this application, the relevant contents of the technical solution of this application are first explained below.

[0049] Currently, box-type transformers can design the number of fans and circulating air volume by estimating the heat dissipation of components such as the transformer within the box-type transformer, providing a wide margin. However, because they fail to account for variations in heat generation under different external environments and transformer loads, this results in high energy consumption after deployment, leading to energy waste. Furthermore, box-type transformer cooling solutions typically utilize a single temperature control device to control a group of fans through convection, without designing different temperature control start and stop temperatures for different external environments and loads, and temperature settings cannot be set in stages. Different external environments, such as different times of day and different seasons, can be affected.

[0050] Figure 1 This is a schematic diagram of the structure of the temperature control and heat dissipation system of the box-type substation provided by the first embodiment of the present utility model. Figure 1 As shown, the temperature control and heat dissipation system of the box-type substation provided by the embodiment of the present invention includes a basic temperature control and heat dissipation device 1 and at least one backup temperature control and heat dissipation device 2, wherein:

[0051] The basic temperature control and heat dissipation device 1 is used to turn on the heat dissipation function under preset temperature conditions; the at least one backup temperature control and heat dissipation device 2 is used to turn on the heat dissipation function under other temperature conditions; the temperature requirements of the other temperature conditions are higher than the temperature requirements of the preset temperature conditions.

[0052] Specifically, the temperature sensor included in the basic temperature control and heat dissipation device 1 can detect the temperature inside the box transformer. If the detected temperature inside the box transformer meets the starting temperature included in the preset temperature condition, the basic temperature control and heat dissipation device 1 will control the corresponding heat dissipation device to start the heat dissipation function to reduce the temperature inside the box transformer and ensure the normal operation of the transformer, high and low voltage cabinets and other equipment in the box transformer. It is understandable that the preset temperature condition can also include a stop temperature, and the stop temperature is lower than the starting temperature. When the temperature inside the box transformer is lower than the stop temperature, the basic temperature control and heat dissipation device 1 will control the corresponding heat dissipation device to turn off the heat dissipation function. Among them, the preset temperature condition is set according to actual needs. For example, the preset temperature condition is to start at more than 50°C, which is not limited in the embodiment of the present utility model.

[0053] When the load of the equipment in the box transformer is large or the external ambient temperature is high, even though the basic temperature control and heat dissipation device 1 has the heat dissipation function turned on, the temperature inside the box transformer continues to rise. When the temperature inside the box transformer meets other temperature conditions, at least one standby temperature control and heat dissipation device 2 will turn on the heat dissipation function to reduce the temperature inside the box transformer. When there are multiple standby temperature control and heat dissipation devices 2, the other temperature conditions may include multiple start-up temperatures, and the multiple start-up temperatures are different from each other. Each standby temperature control and heat dissipation device 2 corresponds to a start-up temperature. It is understandable that the other temperature conditions may also include a stop temperature corresponding to each standby temperature control and heat dissipation device 2. When the temperature inside the box transformer is lower than the stop temperature corresponding to the standby temperature control and heat dissipation device 2, the standby temperature control and heat dissipation device 2 will turn off the heat dissipation function that has been turned on. The temperature requirements of the other temperature conditions are higher than the temperature requirements of the preset temperature conditions. The specific number of standby temperature control and heat dissipation devices 2 is set according to actual needs, such as 1, 2, 3, 4, etc., and is not limited in the embodiments of the present invention.

[0054] For example, Figure 2 As shown, the temperature control and heat dissipation system for a box-type substation provided by an embodiment of the present invention includes a basic temperature control and heat dissipation device 1 and a backup temperature control and heat dissipation device 2. A preset temperature condition is set to be greater than a first temperature, and other temperature conditions are set to be greater than a second temperature, with the second temperature being greater than the first temperature. The basic temperature control and heat dissipation device 1 and the backup temperature control and heat dissipation device 2 constitute a two-stage temperature control and heat dissipation system. The basic temperature control and heat dissipation device 1 detects, via a temperature sensor within the box-type substation, that the temperature within the box-type substation exceeds the first temperature and activates its heat dissipation function. If the temperature within the box-type substation continues to rise after the basic temperature control and heat dissipation device 1 activates its heat dissipation function when the temperature within the box-type substation exceeds the second temperature, the backup temperature control and heat dissipation device 2 activates its heat dissipation function to enhance heat dissipation capacity. The first and second temperatures are set based on actual needs and are not limited by the present embodiment. By configuring the basic temperature control and heat dissipation device 1 and the backup temperature control and heat dissipation device 2, the heat dissipation function of the basic temperature control and heat dissipation device 1 is activated first, and the heat dissipation function of the backup temperature control and heat dissipation device 2 is activated when needed, thereby saving energy. In addition, the standby temperature control and heat dissipation device 2 can also serve as a backup for the basic temperature control and heat dissipation device 1. When the basic temperature control and heat dissipation device 1 fails, the standby temperature control and heat dissipation device 2 can be used to replace the basic temperature control and heat dissipation device 1, thereby improving the reliability of the temperature control and heat dissipation system of the box-type substation. For example, if the temperature difference between day and night in area A is relatively large, Figure 2 The temperature control and heat dissipation system of the box-type substation shown in the figure. The basic temperature control and heat dissipation device 1 meets the basic heat dissipation requirements, and the backup temperature control and heat dissipation device 2 is used to meet the heat dissipation requirements during high daytime temperatures. If the basic temperature control and heat dissipation device 1 fails and cannot be used, the backup temperature control and heat dissipation device 2 can be activated to replace it, providing more time for maintenance of the basic temperature control and heat dissipation device 1.

[0055] For example, Figure 3 As shown, the temperature control and heat dissipation system of the box-type substation provided by the embodiment of the present invention includes a basic temperature control and heat dissipation device 1 and two backup temperature control and heat dissipation devices: a backup temperature control and heat dissipation device 2-1 and a backup temperature control and heat dissipation device 2-1. The basic temperature control and heat dissipation device 1, the backup temperature control and heat dissipation device 2-1 and the backup temperature control and heat dissipation device 2-2 constitute a three-stage temperature control and heat dissipation device. The preset temperature condition is set to be greater than the first temperature, and other temperature conditions are set to include a second temperature and a third temperature, the second temperature is greater than the first temperature, and the third temperature is greater than the second temperature. The basic temperature control and heat dissipation device 1 detects through the temperature sensor in the box transformer that the temperature inside the box transformer is greater than the first temperature, and then turns on the heat dissipation function. If the temperature inside the box transformer still rises after the basic temperature control and heat dissipation device 1 turns on the heat dissipation function, when the temperature inside the box transformer rises to greater than the second temperature, the backup temperature control and heat dissipation device 2-1 turns on the heat dissipation function to enhance the heat dissipation capacity. If the temperature inside the box transformer continues to rise after the basic temperature control heat dissipation device 1 and the backup temperature control heat dissipation device 2-1 turn on the heat dissipation function, when the temperature inside the box transformer rises to greater than the third temperature, the backup temperature control heat dissipation device 2-2 turns on the heat dissipation function to further enhance the heat dissipation capacity. Among them, the first temperature, the second temperature and the third temperature are set according to actual needs, and the embodiment of the present utility model is not limited. By turning on the heat dissipation function of the basic temperature control heat dissipation device 1, the backup temperature control heat dissipation device 2-1 and the backup temperature control heat dissipation device 2-2 under different temperature conditions, energy consumption can be saved. The backup temperature control heat dissipation device 2-1 or the backup temperature control heat dissipation device 2-2 can also serve as a backup for the basic temperature control heat dissipation device 1. When the basic temperature control heat dissipation device 1 fails, the backup temperature control heat dissipation device 2-1 or the backup temperature control heat dissipation device 2-2 can be enabled to replace the basic temperature control heat dissipation device 1, thereby improving the reliability of the temperature control and heat dissipation system of the box-type substation. For example, area B has distinct four seasons, and it can be used Figure 3 The temperature control and cooling system of the box-type substation shown in the figure. In the summer, when temperatures are high, the temperature control and cooling devices can be activated step by step to meet heat dissipation requirements. In spring and autumn, the basic temperature control and cooling device 1 and the backup temperature control and cooling device 2-1 are primarily used, with the backup temperature control and cooling device 2-2 serving as a backup. In winter, the basic temperature control and cooling device 1 is primarily used, with the backup temperature control and cooling devices 2-1 and 2-2 serving as backup.

[0056] The temperature control and heat dissipation system of a box-type substation provided by an embodiment of the present invention includes a basic temperature control and heat dissipation device and at least one backup temperature control and heat dissipation device. The basic temperature control and heat dissipation device is used to turn on the heat dissipation function under preset temperature conditions; the at least one backup temperature control and heat dissipation device is used to turn on the heat dissipation function under other temperature conditions; the temperature requirements of the other temperature conditions are higher than the temperature requirements of the preset temperature conditions. By turning on the heat dissipation function under different temperature conditions by the basic temperature control and heat dissipation device and at least one backup temperature control and heat dissipation device, energy consumption is reduced.

[0057] On the basis of the above embodiments, further, the basic temperature-controlled heat dissipation device 1 is connected to at least one backup temperature-controlled heat dissipation device 2 in a fault-triggered manner. The backup temperature-controlled heat dissipation device 2 connected to the basic temperature-controlled heat dissipation device 1 is put into operation when the basic temperature-controlled heat dissipation device 1 fails, thereby reducing the risk of the basic temperature-controlled heat dissipation device 1 failing to work and causing the temperature inside the box to be too high.

[0058] For example, Figure 2 As shown, the backup temperature control and cooling device 2 is connected to the basic temperature control and cooling device 1 in a fault-triggered manner. When the basic temperature control and cooling device 1 fails, such as a power failure, the backup temperature control and cooling device 2 will be activated to replace the basic temperature control and cooling device 1.

[0059] On the basis of the above embodiments, further, there are multiple backup temperature-controlled heat dissipation devices 2, one of which is connected to at least one other backup temperature-controlled heat dissipation device 2 when a fault is triggered. The other backup temperature-controlled heat dissipation devices 2 connected to the one of the backup temperature-controlled heat dissipation devices 2 are put into operation when the one of the backup temperature-controlled heat dissipation devices fails, thereby reducing the risk of excessive temperature inside the box transformer due to the failure of one of the backup temperature-controlled heat dissipation devices 2 to work.

[0060] For example, Figure 3 As shown, the backup temperature-controlled heat dissipation device 2-1 is connected to the backup temperature-controlled heat dissipation device 2-2 by fault triggering. When the backup temperature-controlled heat dissipation device 2-1 fails, such as a power failure, the backup temperature-controlled heat dissipation device 2-2 will be activated to replace the backup temperature-controlled heat dissipation device 2-1.

[0061] Figure 4 This is a schematic diagram of the structure of the basic temperature control and heat dissipation device provided in the fourth embodiment of the present invention. Figure 4 As shown, based on the above embodiments, the basic temperature control and heat dissipation device 1 further includes a first switch 101, a first temperature controller 102, a first temperature sensor 103 and a first heat dissipation device 104, wherein:

[0062] The first switch 101 is used to connect and disconnect the first power supply circuit of the first temperature controller 102 and the first heat dissipation device 104; the first temperature sensor 103 is used to detect the temperature inside the box-type substation, and the first temperature controller 102 is used to control the start and stop of the first heat dissipation device 104 according to the temperature detected by the first temperature sensor 103 and the preset temperature conditions.

[0063] Specifically, the first switch 101 is closed, supplying power to the first temperature controller 102. A first temperature sensor 103 is located within the transformer and is capable of detecting the temperature within the transformer. The first temperature controller 102 compares the detected temperature with a startup temperature specified in a preset temperature condition. If the detected temperature exceeds the startup temperature specified in the preset temperature condition, the first temperature controller 102 activates the first heat dissipation device 104 to dissipate heat. The first switch 101 can be a miniature circuit breaker, the first heat dissipation device 104 can be a fan or air conditioner, and the first temperature controller 102 can be a temperature controller.

[0064] For example, Figure 5 As shown, the basic temperature control and heat dissipation device 1 includes a miniature circuit breaker 501-1, a temperature controller 502, a temperature sensor 503, and a fan unit 504. The first end of miniature circuit breaker 501-1 is connected to the live wire (L), the second end of miniature circuit breaker 501-1 is connected to the temperature controller 502, the first end of miniature circuit breaker 501-2 is connected to the neutral wire (N), the second end of miniature circuit breaker 501-2 is connected to the temperature controller 502 and the fan unit 504, respectively, and the temperature sensor 503 is connected to the temperature controller 502. When miniature circuit breakers 501-1 and 501-2 are closed, the temperature controller 502 is powered on and operates. Temperature sensor 503 detects temperature T1 within the transformer. Temperature controller 502 compares temperature T1 with the startup temperature T0. If temperature T1 is greater than the startup temperature T0, temperature controller 502 controls fan unit 504 to power on and operate, thereby reducing the temperature within the transformer. Temperature sensor 503 can detect the temperature within the transformer at predetermined intervals. After a certain period of time, if temperature controller 502 compares the re-detected temperature T1 and finds it less than the shutdown temperature T2, temperature controller 502 controls fan unit 504 to power off and cease operation. Fan unit 504 may include multiple fans.

[0065] Figure 6 This is a schematic diagram of the structure of the basic temperature control and heat dissipation device provided by the sixth embodiment of the present invention. Figure 6As shown, on the basis of the above embodiments, the basic temperature control and heat dissipation device 1 further includes a first conversion switch 105, which is arranged on the first power supply circuit and is connected to a backup temperature control and heat dissipation device 2, and is used to detect a fault in the first power supply circuit, and after detecting a fault in the power supply circuit, trigger the connected backup temperature control and heat dissipation device 2 to start working.

[0066] Specifically, the basic temperature-controlled heat dissipation device 1 further includes a first transfer switch 105, which is disposed on the first power supply circuit and is capable of detecting a fault in the first power supply circuit. When the first power supply circuit fails, the first heat dissipation device 104 ceases operation, and the first transfer switch 105 triggers the backup temperature-controlled heat dissipation device 2 to activate its heat dissipation function, thereby providing backup protection for the basic temperature-controlled heat dissipation device 1 by the backup temperature-controlled heat dissipation device 2, thereby preventing the failure of the basic temperature-controlled heat dissipation device 1 to dissipate heat in a timely manner. The first transfer switch may be an intermediate relay.

[0067] For example, the first conversion switch 105 is connected to the power supply circuit of the heat dissipation device of the standby temperature-controlled heat dissipation device 2. When the first power supply circuit fails, the first conversion switch 105 can close the power supply circuit of the heat dissipation device of the standby temperature-controlled heat dissipation device 2, so that the heat dissipation device of the standby temperature-controlled heat dissipation device 2 can operate.

[0068] On the basis of the above embodiments, further, the first temperature controller 102 is connected to a backup temperature control and heat dissipation device 2 , and when an internal failure occurs in the first temperature controller 102 , the connected backup temperature control and heat dissipation device 2 is started.

[0069] Specifically, when the first temperature controller 102 has an internal fault, the heat dissipation device of the backup temperature control and heat dissipation device 2 can be directly started through the fault output contact to prevent overheating inside the box transformer from damaging the equipment inside the box transformer when the basic temperature control and heat dissipation device 1 fails and cannot dissipate heat.

[0070] Figure 7 This is a schematic diagram of the structure of the standby temperature control and heat dissipation device provided by the seventh embodiment of the present invention. Figure 7 As shown, based on the above embodiments, the standby temperature control and heat dissipation device 2 further includes a second switch 201, a second temperature controller 202, a second temperature sensor 203 and a second heat dissipation device 204, wherein:

[0071] The second switch 201 is used to connect and disconnect the second power supply circuit of the second temperature controller 202 and the second heat dissipation device 204; the second temperature sensor 203 is used to detect the temperature inside the box-type substation, and the second temperature controller 202 is used to control the start and stop of the second heat dissipation device 204 according to the temperature detected by the second temperature sensor 203 and the other temperature conditions.

[0072] Specifically, the second switch 201 is closed, supplying power to the second temperature controller 202. A second temperature sensor 203 is located within the transformer and is capable of detecting the temperature within the transformer. The second temperature controller 202 compares the detected temperature with other preset temperature conditions, including a start-up temperature. If the detected temperature is greater than the other preset temperature conditions, including the start-up temperature, the second temperature controller 202 activates the second heat dissipation device 204 to dissipate heat. The second switch 201 can be a miniature circuit breaker, the second heat dissipation device 204 can be a fan or air conditioner, and the second temperature controller 202 can be a temperature controller.

[0073] Figure 8 This is a schematic diagram of the structure of the standby temperature control and heat dissipation device provided in the eighth embodiment of the present invention. Figure 8 As shown, on the basis of the above embodiments, the backup temperature-controlled heat dissipation device 2 further includes a second conversion switch 205, which is arranged on the second power supply circuit and is connected to another backup temperature-controlled heat dissipation device 3, and is used to detect a fault in the second power supply circuit, and after detecting a fault in the second power supply circuit, trigger the other connected backup temperature-controlled heat dissipation device 3 to start working.

[0074] On the basis of the above embodiments, further, the second temperature controller 202 is connected to another standby temperature-controlled heat dissipation device 3 , and when an internal failure occurs in the second temperature controller 202 , the other connected standby temperature-controlled heat dissipation device 3 is activated.

[0075] Specifically, when the second temperature controller 202 has an internal fault, the heat dissipation device of other backup temperature control and heat dissipation devices 3 can be directly started through the fault output contact to prevent overheating inside the box transformer and damage to the equipment inside the box transformer when the backup temperature control and heat dissipation device 2 fails to dissipate heat.

[0076] On the basis of the above embodiments, further, the basic temperature-controlled heat dissipation device 1 and at least one backup temperature-controlled heat dissipation device 2 share a temperature sensor.

[0077] Specifically, the basic temperature control and heat dissipation device 1 and the backup temperature control and heat dissipation device 2 both need to obtain the temperature inside the box transformer to decide whether to start. A temperature sensor will be set inside the box transformer to detect the temperature inside the box transformer. The basic temperature control and heat dissipation device 1 and the backup temperature control and heat dissipation device 2 can share the temperature sensor to save the cost of the temperature control and heat dissipation system of the box-type substation.

[0079] The basic temperature control and heat dissipation device 91 includes a miniature circuit breaker 91-1, a temperature controller 91-2, a temperature sensor 91-3, a fan unit 91-4, and an intermediate relay 91-5. The miniature circuit breaker 91-1 is provided on the first power supply circuit of the temperature controller 91-2 and the fan unit 91-4, and is used to connect and disconnect the first power supply circuit. The temperature sensor 91-3 is used to detect the temperature within the box-type substation. The temperature controller 91-2 is used to control the start and stop of the fan unit 91-4 based on the temperature detected by the temperature sensor 91-3 and the preset temperature condition.
