The air outlet pipe 5 penetrates through the main frame 4, and one end of the air outlet pipe, which is far away from the blower 2, is erected on the transformer 3 to dissipate heat of the transformer 3.
Referring to fig. 1 and 3, further, the transformer 3 is fixedly connected with the main frame 4 through a connecting plate 6.

One end of the connecting plate 6, which is far away from the main frame 4, is connected with a frame body 7 for mounting the transformer 3. The transformer 3 is fixedly mounted on the frame body 7 through bolts.
Referring to fig. 1 and 2, it is worth explaining that a certain gap exists between the bottom end of the transformer 3 and the frame body 7. When the transformer 3 is in an operating state, the amount of heat generated at the bottom end of the transformer 3 is higher than at other positions. In order to accurately cool the transformer 3, the two air outlet pipes 5 are erected at two sides of the bottom end of the transformer 3, one end of each air outlet pipe 5, which is far away from the air feeder 2, is of a closed structure, and a plurality of air holes 51 are formed in the corresponding end portion of each air outlet pipe.

Referring to fig. 1 and 3, considering that the space inside the work box 1 is large, the process of the blower 2 pumping outside air to cool the transformer 3 is long, and for this reason, the present application further includes a transformer box 8 covering the transformer 3.

Meanwhile, the transformer box 8 is further provided with an air outlet 83, so that the speed of air circulation is increased and the heat dissipation and cooling effects of the transformer 3 are improved in the process of cooling the transformer 3.

With reference to fig. 1 and 4, furthermore, the present application also comprises drive means 9 for driving the activation of the two blowers 2. For the sake of clarity of description, the two blowers 2 will be referred to as a first blower and a second blower, respectively, hereinafter.
Specifically, the driving device 9 includes a temperature detection module 91 and a process control module 92.
The temperature detection module 91 is configured to detect a temperature around the transformer 3 and output a temperature detection signal. The temperature detection module 91 may employ other measuring instruments having a temperature sensing function, such as a temperature sensor. In order to make the measurement result more accurate, the temperature detection module 91 is preferably installed in the transformer tank 8.

The second processing unit 922 is connected to the temperature detection module 91, and is configured to receive the temperature detection signal and output a second heat dissipation signal when a temperature value reflected by the temperature detection signal is higher than a second temperature preset value.
It can be understood that the first processing unit 921 includes a first comparator N1 and a first preset unit 9211, and the second processing unit 922 includes a second comparator N2 and a second preset unit 9221. Since the first processing unit 921 and the second processing unit 922 operate in the same principle, the first processing unit 921 is taken as an example and will be described in detail below.
The first preset unit 9211 is configured to output a first temperature preset signal reflecting the first temperature preset value. The first preset unit 9211 includes a first fixed resistor R1 and a first sliding rheostat R2, the first fixed resistor R1 and the first sliding rheostat R2 are connected in series to a power supply, the first fixed resistor R1 is arranged near the positive pole of the power supply, and the common end of the first fixed resistor R1 and the first sliding rheostat R2 outputs the first temperature preset signal. The magnitude of the first temperature preset signal can be directly changed by adjusting the resistance value of the first slide rheostat R2, and the larger the resistance value of the first slide rheostat R2 is, the larger the first temperature preset signal is.
The non-inverting input end of the first comparator N1 is connected to the temperature detection module 91 and receives the temperature detection signal, and the inverting input end is connected to the first preset unit 9211 and receives the first temperature preset signal. When the temperature value reflected by the temperature detection signal is higher than the first temperature preset value, the output end of the first comparator N1 outputs a high level, that is, the first comparator N1 outputs a first heat dissipation signal. On the contrary, when the temperature value reflected by the temperature detection signal is lower than the first temperature preset value, the output end of the first comparator N1 outputs a low level, that is, the first comparator N1 does not output the first heat dissipation signal.
It should be noted that the first preset temperature value is lower than the second preset temperature value, so as to turn on a corresponding number of blowers 2 according to the ambient temperature of the transformer 3, so as to save energy while cooling the transformer 3. In the present application, the first temperature preset value is preferably 95 ℃ and the second temperature preset value is preferably 105 ℃.

The control unit 923 preferably employs a controller.
The first blower connection control unit 923 is configured to receive a first start signal and to start when receiving the first start signal.
The first blower connection control unit 923 is configured to receive a second start signal and to start when receiving the second start signal.
In order to avoid unnecessary resource waste, the control unit 923 outputs a turn-off signal to turn off all the blowers 2 when the temperature value reflected by the temperature detection signal is lower than the third temperature preset value. The specific implementation manner of the present invention can refer to the above working principle, which is not described herein, and preferably, the third preset temperature value is 90 ℃.
The implementation principle of the transformer ventilation system in the embodiment of the application is as follows: the blower 2 can extract external air, and the external air is delivered to one end of the air outlet pipe 5 far away from the blower 2 through the air outlet pipe 5, so that the external air flows out from the air holes 51, and further the heat of the transformer 3 is dissipated. Since the heat generated at the lower end of the transformer 3 is large, the external air can flow toward the lower end of the transformer 3 better through the air holes 51, so that the heat dissipation and cooling effects of the transformer 3 are improved. Moreover, the temperature detection module 91 can detect the temperature around the transformer 3, and drive the blowers 2 with different numbers to start to cool the transformer 3, so that the energy can be saved while the transformer 3 is cooled.
The foregoing is a preferred embodiment of the present application and is not intended to limit the scope of the application in any way, and any features disclosed in this specification (including the abstract and drawings) may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
