Fig. 1 is a block diagram of a novel transformer respirator according to an embodiment of the present invention. In fig. 1, the ventilator 10 may include a plurality of sensors 01 and a wireless signal generator 02.
In this embodiment, the sensor 01 and the wireless signal generator 02 are disposed at positions shown in fig. 2. In FIG. 2, the sensor 01 may be located on the inside wall of the respirator 10. The wireless signal generator 02 may be disposed inside the respirator 10, and connected to the sensor 01 through a wireless signal, for transmitting the output signal strength of the sensor 01 to the outside in real time.
In this embodiment, the sensors 01 are distributed on the inner wall of the respirator 10 and are connected with the wireless signal generator 02 through wireless signals. Due to the nature of the attenuation of the output signal strength of the wireless signal with distance, the output signal strength fluctuates within a certain range as the liquid in the transformer fluctuates at the inner wall of the ventilator 10. Then, after the wireless signal generator 02 sends out the output signal strength, the person in the control center can determine whether the inner wall of the respirator 10 has changed by judging the range of the output signal strength, so as to perform corresponding operations. Finally, through the respirator 10, the purpose of remote monitoring of a control center is achieved.
Fig. 3 is a block diagram of a novel transformer respirator according to an embodiment of the present invention. The difference from the respirator shown in fig. 1 is that in fig. 3, the sensor 01 comprises a humidity sensor 03. The humidity sensor 03 can be used to obtain the humidity of the silica gel inside the respirator 10. The wireless signal generator 02 may further be used to send out humidity over a wireless wide area network.
In the prior art, the respirator 10 has the function of breathing out redundant air in the transformer conservator capsule when the transformer is heated and expanded; when the oil temperature of the transformer is reduced and contracted, outside air is sucked in, so that the transformer oil in the oil storage cup filters the outside air, and then the silica gel absorbs moisture which is not filtered out, so that the transformer oil in the transformer is not invaded by the moisture in the outside air, the water content of the transformer oil is always in a standard range, the transformer is prevented from being affected with damp, and the insulation strength of the transformer oil is ensured. In such a background, the silica gel inside the respirator 10 is prone to be excessively humid, and in a state where the humidity is excessively humid, it is obviously difficult for the respirator 10 to perform the above-described functions. In the prior art, people are used to replace the silica gel periodically to avoid failure of the respirator 10 due to high silica gel humidity. Such maintenance is not only costly, but also relies on human experience. Therefore, in this embodiment, by providing the humidity sensor 03 and further sending the humidity measured in real time through the wireless signal generator 02 via the wireless wide area network, the control center can remotely monitor the humidity of the silica gel and take corresponding measures in time.
Further, in addition to the respirator 10 shown in FIG. 3, the respirator 10 may also include a heating device 04, as shown in FIG. 4. The heating device 04 may be disposed inside the respirator 10 and connected to the wireless signal generator 02. The wireless signal generator 02 may be further configured to receive a heating command transmitted from the outside, and transmit the heating command to the heating device 04 when receiving the heating command. The heating device 04 may then be activated to heat the silicone gel inside the respirator 10 upon receiving a heating command.
In the prior art, in the case of determining the humidity of the silica gel inside the respirator 10, a worker goes to the site to replace the silica gel, and heats and evaporates the replaced silica gel for recycling. Thus, in the respirator 10 shown in FIG. 4. The heating device 04 arranged inside the respirator 10 can prevent workers from going to the site to replace silica gel, so that the equipment overhauling and maintaining efficiency is improved.
On the other hand, the utility model discloses still provide a control center, as shown in fig. 5. In fig. 5, the control center may include a wireless signal receiving device 20, a processor 21, and an alarm 22.
In fig. 5, the wireless signal receiving device 20 may be used to receive the output signal strength externally from the ventilator 10 as shown in fig. 1-4. The processor 21 may be connected with the wireless signal receiving apparatus 20 for performing the method as illustrated in fig. 6. In fig. 6, the method may include:
in step S10, the output signal strength is received.
In step S11, the fluctuation range of the output signal intensity is determined.
In step S12, it is determined that the fluctuation range is within a preset first interval;
in step S13, in the case where it is judged that the fluctuation range is within the first interval, it is determined that clogging has occurred inside the respirator.
In the respirator 10, the sensors 01 are distributed on the inner wall of the respirator 10 and are connected with the wireless signal generator 02 through wireless signals. Due to the nature of the attenuation of the output signal strength of the wireless signal with distance, the output signal strength fluctuates within a certain range as the liquid in the transformer fluctuates at the inner wall of the ventilator 10. Then, after the wireless signal generator 02 sends out the output signal intensity, the person in the control center can determine whether the inner wall of the respirator 10 has changed by judging the range of the output signal intensity, so as to perform the corresponding operation (the method shown in fig. 6). Finally, through the respirator 10, the purpose of remote monitoring of a control center is achieved.
In the method illustrated in FIG. 6, the respirator 10 is a flexible structure. Under normal conditions, the side walls of the respirator 10 will deform steadily with the liquid in the transformer. Accordingly, the intensity of the output signal output from the sensor 01 also fluctuates within a certain range. However, if the inside of the respirator 10 is clogged, at this time, the side wall of the respirator 10 temporarily becomes a rigid structure due to the clogging, resulting in a fixed distance between the sensor 01 and the wireless signal generator 02, so that the fluctuation range of the output signal intensity becomes small. Therefore, in this embodiment, the first interval may be a smaller signal fluctuation interval, and specifically, the range point value of the interval may be determined according to the model of the actual sensor 01.
An alarm 22 may be connected to the processor 21 for activation to sound an alarm in the event that it is determined that an occlusion has occurred within the respirator 10.
In one embodiment of the present invention, the processor may also be used to perform a method as illustrated in fig. 7. In fig. 7, the method may include:
in step S20, determining whether the fluctuation range is within a preset second interval, wherein the second interval is greater than the first interval;
in step S21, in the case where it is judged that the fluctuation range is in the second section, it is determined that the respirator is normal.
In the method illustrated in FIG. 7, the respirator 10 is a flexible structure. Under normal conditions, the side walls of the respirator 10 will deform steadily with the liquid in the transformer. Accordingly, the intensity of the output signal output from the sensor 01 also fluctuates within a certain range. In addition, in order to distinguish from the first section shown in fig. 6, the second section may be larger in range than the first section.
In one embodiment of the present invention, the processor 21 may also be further configured to perform a method as illustrated in fig. 8. In fig. 8, the processor 21 may be configured to:
in step S30, it is determined whether the fluctuation range is within a preset third interval, wherein the range of the third interval is greater than the second interval.
In step S31, in the case where it is judged that the fluctuation range is in the third section, it is determined that the inner wall of the respirator 10 is broken.
In the method illustrated in FIG. 8, the respirator 10 is a flexible structure. Under normal conditions, the side walls of the respirator 10 will deform steadily with the liquid in the transformer. Accordingly, the intensity of the output signal output from the sensor 01 also fluctuates within a certain range. However, when the inner wall of the respirator 10 is ruptured, the distance between the sensor 01 and the wireless signal generator 02 is drastically changed as the ruptured inner wall swings, thereby causing drastic fluctuation in the intensity of the output signal. Therefore, in fig. 8, the range of the third section is larger than the second section. When the output signal strength is judged to be in the third interval, it can be determined that the inner wall of the respirator 10 is broken.
The alarm 22 may then be further configured to activate to sound an alarm in the event that a rupture is determined within the respirator 10.
In one embodiment of the present invention, the wireless signal receiving device 20 may be further configured to receive a signal of external humidity. The processor may then be further configured to perform the method as illustrated in fig. 9. In fig. 9, the method may include:
in step S40, it is determined whether the humidity is greater than a preset humidity threshold;
in step S41, in the case that the humidity is judged to be greater than the humidity threshold, it is determined that the humidity of the silica gel inside the respirator 10 is too high;
in step S42, the wireless signal receiving device is controlled to send a heating command to the outside.
In the prior art, the respirator 10 has the function of breathing out redundant air in the transformer conservator capsule when the transformer is heated and expanded; when the oil temperature of the transformer is reduced and contracted, outside air is sucked in, so that the transformer oil in the oil storage cup filters the outside air, and then the silica gel absorbs moisture which is not filtered out, so that the transformer oil in the transformer is not invaded by the moisture in the outside air, the water content of the transformer oil is always in a standard range, the transformer is prevented from being affected with damp, and the insulation strength of the transformer oil is ensured. In such a background, the silica gel inside the respirator 10 is prone to be excessively humid, and in a state where the humidity is excessively humid, it is obviously difficult for the respirator 10 to perform the above-described functions. In the prior art, people are used to replace the silica gel periodically to avoid failure of the respirator 10 due to high silica gel humidity. Such maintenance is not only costly, but also relies on human experience. Therefore, in this embodiment, when the humidity is determined to be greater than the humidity threshold, it can be determined that the humidity of the silica gel inside the ventilator 10 is too high, so as to control the wireless receiving device to send a heating instruction, and the heating instruction can activate the heating device 04 inside the ventilator 10, thereby implementing maintenance on the ventilator 10.
In addition, the alarm 22 may be any of a variety of alarm prompting devices known to those skilled in the art, including but not limited to buzzers, voice devices, indicator lights, and the like. In a preferred example of the present invention, the alarm 22 may be a different colored indicator light in order to distinguish between different levels of alarm and to accommodate the environmental conditions that the control center needs to maintain quiet and tidy on site. Further, the color of the indicator light corresponding to the alarm 22 may be different for different types and severity of operating conditions. For example, in a normal state, the alarm 22 may be a green indicator light. The alarm 22 may be a yellow indicator light under the condition that the silica gel needs to be heated and dried. In the event that the internal walls of the respirator 10 are breached, the alarm 22 may be a red indicator light, since the conditions are more critical.
In still another aspect, the present invention further provides a monitoring system for a novel transformer, which may include a respirator and a control center as described above. The specific operation of the monitoring system is described in detail above in connection with the ventilator and the control center, and therefore, the detailed description thereof is omitted here.
