Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, and in particular to a transformer pile head temperature measuring device. Background Technology

[0002] In power system operation, transformers are critical equipment, and temperature monitoring of their terminals is essential. Accurate temperature data is crucial for judging the operating status of transformers and preventing faults. Currently, using infrared temperature sensors for non-contact temperature measurement of transformer terminals has become a commonly used temperature monitoring method due to its advantages such as ease of operation and real-time performance.

[0003] In practical applications, transformers are often located in complex outdoor environments, where dust and impurities easily adhere to the surface of the pile heads. This dust covers the pile head surface, altering its infrared radiation characteristics and causing deviations in the temperature data acquired by the infrared temperature sensor. This results in the data failing to accurately reflect the actual temperature of the pile head, potentially leading to serious power accidents. Existing transformer pile head temperature measuring components mostly focus only on temperature measurement, lacking effective dust removal measures. Consequently, it is inconvenient to clean the surface of the pile head when measuring its temperature, which can easily affect the accuracy of the temperature measurement. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a transformer pile head temperature measuring device. This device can solve the problem that most existing transformer pile head temperature measuring components only focus on the temperature measurement function and lack effective dust removal measures. As a result, it is inconvenient to clean the surface of the pile head when the temperature measuring component is measuring the temperature, which can easily affect the accuracy of the temperature measurement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer pile head temperature measuring device, comprising a transformer, three transformer pile heads fixedly installed at the top of the transformer, two brackets fixedly installed at the bottom of the transformer, each bracket having a threaded hole inside, a temperature display fixedly installed on one side of the transformer, a fixing plate fixedly connected to the top of the transformer, a temperature measuring and dust removal assembly provided on one side of the fixing plate, the temperature measuring and dust removal assembly comprising a semi-circular block located on one side of the transformer pile head, a groove provided at one end of the semi-circular block, an infrared temperature sensor fixedly installed inside the groove, the infrared temperature sensor being wirelessly connected to the temperature display, the infrared temperature sensor being located on one side of the corresponding transformer pile head, and six dust removal pipes fixedly installed at one end of the semi-circular block, the six dust removal pipes being located on both sides of the groove respectively.

[0024] Please see Figure 1-4This utility model provides a technical solution: a transformer pile head temperature measuring device, including a transformer 1, three transformer pile heads 2 are fixedly installed on the top of the transformer 1, two brackets 14 are fixedly installed on the bottom of the transformer 1, and threaded holes 15 are opened inside the two brackets 14. A temperature display 16 is fixedly installed on one side of the transformer 1, a fixing plate 3 is fixedly connected to the top of the transformer 1, and a temperature measuring and dust removal component is provided on one side of the fixing plate 3. The temperature measuring and dust removal component includes a semi-circular block 9, which is located on one side of the transformer pile head 2. A groove 10 is opened at one end of the semi-circular block 9, and an infrared temperature sensor 12 is fixedly installed inside the groove 10. The infrared temperature sensor 12 is wirelessly connected to the temperature display 16 and is located on one side of the corresponding transformer pile head 2. Six dust removal pipes 11 are fixedly installed at one end of the semi-circular block 9, and the six dust removal pipes 11 are respectively located on both sides of the groove 10.

[0025] Furthermore, the interior of the semicircular block 9 is provided with an air duct 13, and the interior of the air duct 13 is connected to the interior of the six dust removal pipes 11.

[0026] Furthermore, a connecting hose 8 is fixedly installed at the top of the semi-circular block 9, and the interior of the connecting hose 8 is connected to the interior of the air duct 13.

[0027] Furthermore, there are three temperature measurement and dust removal components, all of which have the same internal structure and are located on one side of the three transformer terminals 2.

[0028] Furthermore, three electric telescopic rods 7 are fixedly installed on one side of the fixed plate 3. The output ends of the three electric telescopic rods 7 slide through the interior of the fixed plate 3 and are respectively fixedly connected to one end of the three semicircular blocks 9.

[0029] Furthermore, an air supply pipe 4 is fixedly installed on the top of the fixing plate 3, and the interior of the air supply pipe 4 is connected to the interior of three connecting hoses 8 respectively.

[0030] Furthermore, a fan 6 is fixedly installed at the top of the transformer, and an air outlet pipe 5 is fixedly installed at the output end of the fan 6. The end of the air outlet pipe 5 away from the fan 6 is fixedly connected to one end of the air supply pipe 4.

[0031] Furthermore, regarding the temperature measurement function, when the device is put into operation, the three electric telescopic rods 7 are in their initial state, positioning the semicircular block 9 on one side of the corresponding transformer terminal 2, so that the infrared temperature sensor 12 in the groove 10 can accurately align with the transformer terminal 2. The infrared temperature sensor 12, based on the principle of infrared radiation, senses the infrared radiation energy emitted by the transformer terminal 2 and converts it into an electrical signal. This electrical signal is wirelessly transmitted to the temperature display 16. The temperature display 16 processes and analyzes the electrical signal and displays the temperature data of the transformer terminal 2 in real time in digital or graphical form. By viewing the temperature display 16, the staff can intuitively grasp the operating temperature of the transformer terminal 2. When the temperature is abnormal, they can take corresponding measures in time to avoid safety accidents caused by excessive temperature.

[0032] Furthermore, regarding the dust removal function, after the fan 6 is started, the airflow generated by the fan 6 is delivered to the air supply pipe 4 through the air outlet pipe 5. Then, the airflow inside the air supply pipe 4 can pass through the connecting hose 8 and the inside of the air duct 13 in sequence, and finally spray out from the six dust removal pipes 11. The airflow sprayed out from the six dust removal pipes 11 can effectively sweep the surface of the transformer terminal 2, blowing away the dust attached to its surface, thereby preventing dust from accumulating on the surface of the transformer terminal 2. This ensures that when the infrared temperature sensor measures the temperature, the surface of the transformer terminal will not be affected by excessive dust, thus ensuring the accuracy of the temperature measurement by the infrared temperature sensor 12.

[0033] Furthermore, when the position of the temperature measuring component needs to be adjusted, the electric telescopic rod 7 comes into play. By controlling the extension and retraction of the electric telescopic rod 7, the semicircular block 9 can be moved within a certain range, thereby allowing the dust removal pipe 11 to flexibly approach or move away from the transformer terminal 2, thus facilitating the maintenance of the transformer terminal 2 by the staff, and thus enabling the temperature measuring device to be used better.
