Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The rectifier transformer can be used in a scene with high power consumption, and a large amount of power can be consumed in a short time. The load born by the rectifier transformer is far higher than that of the common transformer, and the cooling requirement on the rectifier transformer is higher than that of the common transformer.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a rectifying and transforming apparatus 10 according to an embodiment of the present disclosure.
As shown in fig. 1, the rectifying transformer apparatus 10 includes a rectifying transformer 100.
Wherein, a plurality of groups of cooling fins 101 are disposed on the rectifier transformer 100. This rectifier transformer 100 adopts the oil circulation mode to carry out the oil cooling, can assist the oil cooling through the multiunit fin 101 that sets up.
The inventors have studied and found that if the natural cooling is performed only by means of the oil circulation and the heat sink 101, a large amount of heat is generated as the rectifier transformer 100 operates, and the temperature of the heat sink 101 may increase. The stationary heat sink 101 cools itself at a natural temperature, and the cooling efficiency is low. Therefore, when the load of the rectifier transformer 100 is large, the heat is large, and if the heat sink 101 does not meet the requirement of cooling operation, the rectifier transformer 100 will generate heat too high to cause the expansion and crack of the transformer outer body, which results in oil leakage and fire. Therefore, if only oil circulation and the cooling fins 101 are adopted for natural cooling, the cooling effect may be relatively weak, the working efficiency of the rectifier transformer 100 may be relatively low, the normal operation of the large rectifier transformer 100 may be affected, and the potential safety hazard is high. The large rectifier transformer 100 may be a 2200KVA capacity transformer.
Therefore, a cooling system capable of performing targeted heat dissipation for the heat dissipation fins 101 is provided in the embodiment of the present application. The cooling system includes: a temperature sensing device, a control apparatus 200, and at least one fan 106. That is, the rectification transformer apparatus 10 provided in the embodiment of the present application includes components in the cooling system in addition to the rectification transformer 100.
In the rectifier transformer device 10 provided in the embodiment of the present application, in order to perform targeted heat dissipation on the heat dissipation fins 101, a temperature sensing device is disposed on each of the plurality of sets of heat dissipation fins 101. Each temperature sensing device is connected to the control apparatus 200. The control device 200 may be mounted on a case of the rectifier transformer 100.
The rectifier transformer 100 is provided with a guide rail 104, and the at least one fan 106 is mounted on the guide rail 104. The at least one fan 106 is movable along the rail 104 to move to a position where each of the heat sinks 101 is located to perform a targeted heat dissipation for the heat sink 101. It will be appreciated that the shape of the rail 104 is dependent upon the particular location at which the heat sink 101 is deployed, so long as the fan 106 is able to move along the rail 104 and close to the heat sink 101 to provide a targeted cooling of the heat sink 101.
The temperature sensing device is configured to detect a temperature of the heat sink 101, and may send collected temperature data of the heat sink 101 to the control device 200.
The control device 200 is configured to determine a target heat sink 101 from the plurality of sets of heat sinks 101 according to the temperature data collected by the temperature sensing device, and control a target fan 106 of the at least one fan 106 to cool the target heat sink 101.
Among them, the control apparatus 200 can identify the temperature data in each group of the heat sinks 101 individually to identify the heat sink 101 whose temperature data exceeds the set temperature as the target heat sink 101. Based on the determined target heat sink 101, the control device 200 may determine the target fan 106 from the at least one fan 106 according to the current state of the at least one fan 106, and then control the target fan 106 to perform the cooling process on the determined target heat sink 101.
In one example, 5 sets of heat sinks 101 may be disposed on one side of the rectifier transformer 100, and each set of heat sinks 101 in the 5 sets of heat sinks 101 includes one or more closely spaced composite heat sinks 101. Each set of fins 101 is provided with a temperature detection device. The temperature detection means may be used to periodically send the temperature of the corresponding heat sink 101 to the control device 200 for the control device 200 to perform temperature identification. The temperature detection device may also identify the temperature by itself, and when the acquired and identified temperature exceeds the set temperature, a trigger signal is sent to the control device 200, so that the control device 200 determines the target heat sink 101 according to the trigger signal, thereby controlling the target fan 106 to cool the target heat sink 101.
In the rectification transformer device 10 provided by the embodiment of the application, because the plurality of groups of cooling fins 101 are arranged to perform heat dissipation treatment on the rectification transformer 100, and at least one fan 106 is arranged to perform targeted cooling treatment on the cooling fins 101, dual efficient cooling can be realized, and a better cooling effect is achieved. Because each group of cooling fins 101 is provided with a temperature sensing device capable of collecting temperature data of the cooling fins 101, and the control device 200 can determine a target cooling fin 101 from the plurality of groups of cooling fins 101 according to the temperature data of each group of cooling fins 101, and control the target fan 106 to perform cooling processing on the target cooling fin 101, so that each group of cooling fins 101 can be subjected to targeted cooling, compared with a mode of cooling all the cooling fins 101 by continuously turning on all the fans 106, the implementation mode can perform targeted cooling on each cooling fin 101 by the fans 106 capable of moving along the guide rail 104 under the condition that the temperatures of each cooling fin 101 are different, thereby reducing power consumption and saving energy. Therefore, the cooling of the heat sink 101 can be achieved in a targeted manner, and low-power consumption cooling can be achieved.
For the large rectifier transformer 100 with many cooling fins 101, it is not necessary to adopt the fans 106 to cool all the cooling fins 101 simultaneously in a targeted cooling manner, it is not necessary to set corresponding fans 106 for each group of cooling fins 101, and the number of the fans 106 can be reduced.
For a large rectifier transformer 100 exposed outdoors, due to the influence of factors such as season changes, temperature differences between morning and evening, and sun irradiation, temperature differences may exist between different heat dissipation fins 101 on the rectifier transformer 100, and the different heat dissipation fins 101 on the same rectifier transformer 100 may have differences in shape and size, which also causes temperature differences among the heat dissipation fins 101 when the rectifier transformer 100 operates. By adopting the movable fan 106, the embodiment capable of cooling the radiating fins 101 in a targeted manner is provided, the cooling treatment efficiency of the rectifier transformer 100 can be improved, and energy can be saved.
Optionally, to reduce wiring difficulties, the temperature sensing device may include a temperature sensing transmitter 102, a temperature sensing receiver 103. Wherein each temperature sensing transmitter 102 corresponds to one temperature sensing receiver 103. The temperature sensing transmitter 102 is configured to transmit the collected temperature data to the temperature sensing receiver 103, and the temperature sensing receiver 103 is configured to transmit the received temperature data to the control device 200.
Wherein, the temperature sensing transmitter 102 is mounted on the heat sink 101. The temperature-sensitive receiver 103 may be mounted on the casing of the rectifier transformer 100, on the rail 104, or on the fan 106. As long as the temperature-sensing transmitter 102 and the control device 200 can be connected to the temperature-sensing receiver 103 in communication. In one example, to reduce wiring difficulties, the temperature sensitive receiver 103 is mounted on the housing of the control device 200.
Through the implementation manner, the temperature data of each group of the cooling fins 101 can be wirelessly transmitted to the control device 200, so that potential safety hazards caused by additional wiring on the cooling fins 101 can be avoided.
Optionally, the control device 200 may include a first controller 210 and at least one second controller 220. The at least one fan 106 is connected to the at least one second controller 220. Each of the at least one second controller 220 is connected to the first controller 210.
The first controller 210 is configured to trigger an operation of a target controller in the at least one second controller 220 when the target heat sink 101 is determined, so that the target controller controls the target fan 106 to cool the target heat sink 101.
The first controller 210 may determine the target heat sink 101 according to the temperature data collected by each temperature collection device, so as to determine a cooling manner for the target heat sink 101. The second controller 220 may be an executor of the first controller 210, and controls the target fan 106 to operate when triggered by the first controller 210.
In one embodiment, when the temperature sensing receiver 103 detects that the temperature of the heat sink 101 exceeds a set temperature (e.g., exceeds 60 degrees celsius) by the presence of the pair of temperature sensing transmitters 102, the temperature sensing receiver 103 sends the detected temperature data to the first controller 210 or sends a trigger signal to the first controller 210. When receiving the temperature data or the trigger signal, the first controller 210 determines which set of heat sinks 101 has an excessively high temperature and reaches the temperature of which degree centigrade according to the temperature sensing device sending the temperature data/the trigger signal, and based on this, the first controller 210 sends a start instruction to the target controller corresponding to the target fan 106, so as to control the target fan 106 to dissipate the heat of the heat sinks 101 having the excessively high temperature.
For the heat dissipation fins 101 with different temperatures, different rotation speeds can be adopted for cooling. For example, a plurality of temperature ranges may be set in advance, each temperature range corresponding to one rotation speed, and the rotation speed of the target fan 106 may be determined by matching the temperature range corresponding to the target heat sink 101.
In one example, the cooling of the heat sink 101 at 60 degrees celsius or less may be performed without the fan 106, and the cooling of the heat sink 101 at more than 80 degrees celsius may be performed by a cooling system other than fan cooling (e.g., a system related to oil replacement). For the case of exceeding 60 degrees celsius and being lower than 80 degrees celsius, a plurality of temperature intervals may be set and a rotation speed may be set for each temperature interval, so that the cooling fins 101 in each temperature interval may be cooled at a corresponding rotation speed. It is understood that values of 60, 80 degrees celsius, etc. are merely illustrative.
Optionally, the guide rail 104 is provided with a guide rail wheel 105 and a motor for driving the guide rail wheel 105 to rotate. The rail wheels 105 have a plurality of sets, each set of rail wheels 105 in the plurality of sets of rail wheels 105 being adapted to carry one fan 106. Therefore, when the plurality of fans 106 are present in the rectification and transformation device 10, and the target fan 106 needs to be moved to the position of the target heat sink 101, the first controller 210 controls the motor corresponding to the target fan 106 to rotate, so that the guide rail wheel 105 corresponding to the target fan 106 is driven to rotate under the rotation of the motor, so that the target fan 106 is moved along the guide rail 104 under the driving of the guide rail wheel 105. When the target fan 106 moves to the position of the target heat sink 101, under the triggering action of the first controller 210, the target controller corresponding to the target fan 106 can control the target fan 106 to rotate at the set rotation speed, so as to cool the target heat sink 101.
Through the implementation manner, each fan 106 can move on the guide rail 104 according to the movement of the guide rail wheel 105, so that the targeted heat dissipation fins 101 in the multiple groups of heat dissipation fins 101 can be subjected to targeted heat dissipation, and the power consumption can be reduced.
Alternatively, the guide rail 104 may be an "i" rail, and the guide rail wheels 105 may run smoothly on the "i" rail, thereby smoothly moving the fan 106.
Alternatively, as shown in fig. 2, a ring track may be provided on the rectifier transformer 100 as the guide rail 104, and at least one fan 106 may be disposed on the ring track 104. The rectifier transformer 100 is approximately rectangular, and a plurality of sets of heat dissipation fins 101 are mounted on the side wall of the rectifier transformer 100. The fans 106 on the ring-shaped guide rails 104 can move along the ring-shaped track, so as to perform targeted cooling on the cooling fins 101 of the rectifier transformer 100 in the middle of the ring-shaped track.
It will be appreciated that the use of the fan 106 for targeted cooling does not necessarily require the fan to be in close proximity to the heat sink 101, and that the fan 106 may be moved from far to near by the guide 104 toward the heat sink 101 to achieve targeted cooling at a relatively close location.
Optionally, as shown in fig. 3, a directional guide plate 107 may be disposed on each fan 106 of the at least one fan 106. The directional guide plate 107 guides the wind direction of the fan 106. The guide plate 107 is movable along the guide rail 104 together with the fan 106.
Under the condition that each fan 106 is provided with the directional guide plate 107 for guiding the wind direction of the fan 106, the wind direction is favorably guided to the proper radiating fins 101, so that the corresponding radiating fins 101 are subjected to targeted heat radiation, the cooling effect of the fan 106 can be maximized, and the overall cooling efficiency is improved.
As an implementation manner, in the case that the rectifier transformer 100 is an oil-immersed transformer, a circulation pump 108 may be disposed between the rectifier transformer 100 and the heat sink 101, and the circulation pump 108 is used for adjusting the flow speed of the oil.
In one example, as shown in fig. 4, the rectifier transformer 100 and the heat sink 101 are connected by a connection pipe. The connection pipes include a first connection pipe 1001 and a second connection pipe 1002. Rectifier transformer 100 and circulating pump 108 are connected by first connecting pipe 1001, and circulating pump 108 and heat sink 101 are connected by second connecting pipe 1002.
Wherein, under the condition that be provided with circulating pump 108 between rectifier transformer 100 and fin 101, can promote oil circulation through circulating pump 108, can accelerate the exchange rate of cold, hot oil to can promote the cold cooling effect of oil.
In one application scenario, as shown in fig. 5, the rectification and transformation device 10 may be connected to an external power control cabinet 20. The external power control cabinet 20 is connected to an electrolytic aluminum device 30.
The rectification and transformation device 10 may be connected to an external power control cabinet through a pipe 1003.
The rectification transformer device 10 can be better applied to electrolytic aluminum scenes, and can meet the transformation requirement of aluminum extraction.
Based on the same inventive concept, the embodiment of the present application further provides a method for cooling the rectifier transformer 100. The method may be applied to the aforementioned rectifying and transforming device 10. A plurality of sets of heat sinks 101 are disposed on the rectifier transformer 100 in the rectifier transformer apparatus 10.
Referring to fig. 6, fig. 6 is a flowchart illustrating a method for cooling the rectifier transformer 100 according to an embodiment of the disclosure.
As shown in FIG. 6, the method includes steps S51-S54.
S51: the temperature of the heat dissipation fins 101 is detected by the temperature sensing device on each of the heat dissipation fins 101 in the plurality of sets of heat dissipation fins 101, and the detected temperature data is sent to the control device 200 in the rectification and transformation device 10.
S52: the control device 200 identifies the temperature data corresponding to each group of the plurality of groups of radiating fins 101 to obtain an identification result.
S53: the target heat sink 101 is determined from the plurality of groups of heat sinks 101 by the control apparatus 200 based on the recognition result, the target heat sink 101 being the heat sink 101 whose temperature data reaches the set temperature.
Among them, the control apparatus 200 may compare the temperature data corresponding to each group of the fins 101 with the set temperature, and take the fin 101 having a temperature greater than the set temperature as the target fin 101.
S54: the control device 200 determines the target fan 106 from the at least one fan 106 of the rectifier transformer device 10 based on the determined target heat sink 101, and controls the target fan 106 to perform the cooling process on the target heat sink 101.
The control device 200 may determine the target fan 106 according to a current status of each fan 106 of the at least one fan 106. For example, the target fan 106 may be determined according to the current position and the current rotation speed of each fan 106, and the target fan 106 may be an originally non-rotating fan 106 or an already rotating fan 106. In one example, if the heat dissipation fins 101 are disposed on four side walls of the rectifier transformer 100, four sets of fans 106 may be disposed on the guide rail 104, and each set of fans 106 may be configured to be dedicated to dissipating heat from the heat dissipation fins 101 on one side wall range, i.e., a moving range may be preset for each set of fans. This facilitates rapid determination of the target fan 106, which simplifies the control logic.
In the method, the temperature sensing devices on each group of cooling fins 101 in the rectifier transformer device 10 detect the temperature of the cooling fins 101, and send the collected temperature data to the control device 200 for processing, after receiving the temperature data, the control device 200 determines the cooling fins 101 with the temperature data reaching the set temperature, that is, selects and determines the target cooling fins 101 from the groups of cooling fins 101, determines the target fan 106 from at least one fan 106 of the rectifier transformer device 10 based on the determined target cooling fins 101, and then controls the target fan 106 to cool the target cooling fins 101 in a targeted manner. Therefore, when the temperature of the heat sink 101 is too high, the fan 106 is controlled to cool the heat sink 101, which is beneficial to performing double cooling on the rectifier transformer 100 through the heat sink 101 and the fan 106, and has a good cooling effect. Compared with the method of continuously turning on all the fans 106 to cool all the heat sinks 101, the method can screen out the target heat sink 101 which needs to be cooled by the fans 106 under the condition that the temperatures of the heat sinks 101 are different, and control the target fans 106 to perform targeted heat dissipation on the target heat sink 101, so that the power consumption can be reduced, and the energy can be saved.
Optionally, the method may further include: the control device 200 determines the rotation rate of the target fan 106 based on the temperature data of the target heat sink 101.
The plurality of temperature intervals and the rotation rate of the fan 106 corresponding to each temperature region may be preset, the control device 200 may match the received temperature data with each temperature interval, determine a target rotation rate corresponding to the temperature interval where the target heat sink 101 is located by matching, and control the target fan 106 to cool the target heat sink 101 at the target rotation rate.
Based on this implementation, the control device 200 can determine the rotation speed of the fan 106 according to the temperature data of the heat sink 101, thereby facilitating the cooling process for the target heat sink 101 with different temperatures at different rotation speeds.
In the case that the rectifier transformer 100 is an oil-immersed transformer and the circulation pump 108 is disposed between the rectifier transformer 100 and the heat sink 101, the method may further include: the circulation pump 108 is controlled by the control device 200 to adjust the flow rate of the oil. Thereby improving the oil cooling effect.

In summary, according to the rectification transformer apparatus 10 and the method for cooling the rectification transformer 100 provided by the embodiment of the present application, the plurality of sets of cooling fins 101 in the rectification transformer 100 can be subjected to targeted heat dissipation by the movable fan 106, so that the rectification transformer 100 can be effectively protected, and the transformer substation related to the rectification transformer 100 can normally operate.
