Description
Technical Field
[0001] This utility model relates to the field of transformer equipment, and in particular to transformer equipment with a temperature warning device. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In electrical equipment and wireless circuits, it is commonly used for voltage step-up and step-down, impedance matching, and safety isolation. Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities and other fields.
[0003] Existing transformer equipment typically cannot monitor temperature in real time during use, which may prevent timely detection of safety hazards such as transformer overheating, increasing the risk of accidents and making it difficult for maintenance personnel to accurately judge the operating status of the equipment.
[0004] Therefore, to address the issue that real-time temperature monitoring is often impossible, which may lead to the failure to detect safety hazards such as transformer overheating in a timely manner and increase the risk of accidents, a transformer device with a temperature warning system can be designed. This system involves opening a probe hole at the top of the transformer, allowing a probe to penetrate deep into the transformer to measure the internal temperature, and installing temperature-sensing patches on the surface of the transformer to simultaneously collect temperature data from both the external and internal parts of the transformer. The system can then issue a warning via alarm lights, thereby facilitating the resolution of the aforementioned problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-5This utility model provides an embodiment of a transformer device with a temperature warning device, including a transformer body 1, a fixing base 3, a multi-segment warning light 2, a temperature measuring component, and a temperature measuring strip 5. A multi-segment warning light 2 for warning is fixedly installed at the upper edge of the front end of the transformer body 1. A fixing base 3 is fixedly installed on one side of the upper end of the transformer body 1. A fixing groove 11 is opened on the surface of the fixing base 3. A temperature measuring component for measuring the internal temperature of the transformer is fixedly installed inside the fixing groove 11.

The upper shell 402 and the lower shell 401 are matched and fastened to each other. A temperature measuring strip 5 for measuring the surface temperature of the transformer body 1 is provided on one side of the temperature measuring component.
[0023] Please see Figures 1-3 In this embodiment, two sets of lamp holders 6 are spaced apart at the upper edge of the front end of the transformer body 1. The inner side of each set of lamp holders 6 is provided with a lamp groove 7. The two ends of the multi-segment warning light 2 extend into the interior of the lamp groove 7. A wire hole 8 is provided in the center of one set of lamp holders 6. One end of the multi-segment warning light 2 is provided with a primary conduit. A temperature measuring hole 9 is provided on one side of the upper end of the transformer body 1. By combining the two sets of lamp holders 6, the multi-segment warning light 2 can be fixed to the front end of the transformer body 1, providing a clear and conspicuous warning to the staff through the change of light. Mounting plates 12 are provided on both sides of the fixing seat 3. Two sets of female mounting holes 13 are symmetrically provided on the surface of the mounting plates 12. A corresponding female mounting hole 10 is provided on one side of the upper end of the transformer body 1. By combining the female mounting hole 10 with the female mounting hole 13, when installing the fixing seat 3, the staff can screw the capped bolt from the female mounting hole 13 into the female mounting hole 10, thereby installing the fixing seat 3 on one side of the upper end of the transformer body 1.
[0024] Please see Figures 2-4 In this embodiment, one end of the fixing base 3 is provided with a through hole 14 corresponding to the temperature measuring hole 9, and the lower end of the fixing base 3 is provided with an insulating rubber pad 15. The insulating rubber pad 15 can prevent the circuit interference of the transformer body 1 from interfering with the temperature measuring accuracy of the temperature measuring component. Multiple sets of temperature measuring patches 16 are linearly provided on the surface of the temperature measuring band 5. Magnetic strips 17 are provided on both sides of the temperature measuring band 5. A cable holder 18 is fixedly installed at one end of the temperature measuring band 5. A secondary cable tube is provided at the upper end of the cable holder 18. Through the magnetic strips 17, the operator can attach the temperature measuring band 5 to a suitable position according to different transformer bodies 1. By combining multiple sets of temperature measuring patches 16, the temperature measuring band 5 can measure the temperature of different positions on the outer end of the transformer body 1 and take the average value. When the temperature measuring patch 16 contacts the position where the temperature needs to be measured, the heat will be transferred to the thermistor material in the temperature measuring patch 16 through thermal conduction, causing the resistance value to change to calculate the temperature.
[0025] Please see Figures 3-5 In this embodiment, a circuit board 405 is fixedly installed between the upper shell 402 and the lower shell 401. A battery pack is fixedly installed at the lower end of the circuit board 405 and is electrically connected to the circuit board 405. A control module 406 (model Cortex-M3), a wireless module 407 (model CC1310), a temperature measuring module 408 (model WG22701), and an interface module are sequentially installed on the surface of the circuit board 405. 409. A cable hole 404 is provided at one end of the upper shell 402 and lower shell 401 near the interface module 409. Connection holes 403 are provided on both sides of the upper shell 402 and lower shell 401 near the interface module 409. The end of the primary conduit furthest from the multi-segment warning light 2 passes through the cable hole 8 and is electrically connected to the connection hole 403 and the interface module 409. The end of the secondary conduit furthest from the cable holder 18 passes through the connection hole 403 and is electrically connected to the interface module 409. This is achieved through the control module 406, wireless module 407, and measuring... The temperature measurement module 408 and the interface module 409 are combined to enable the control module 406 to collect temperature measurement data through the temperature measurement module 408 during operation, and to wirelessly transmit the data to the terminal for processing via the wireless module 407. The temperature measurement module 408 calculates the temperature based on the resistance change between the temperature sensing patch 16 and the temperature sensing probe 412, and connects the temperature sensing probe 412 and the temperature sensing strip 5 via the interface module 409. The front end of the interface module 409 is equipped with a temperature sensing cable 410, one end of which... The temperature measuring cable 410 is connected to the interface module 409 through the cable hole 404. The other end of the temperature measuring cable 410 extends into the transformer through the through hole 14 and the temperature measuring hole 9. The other end of the temperature measuring cable 410 is provided with a temperature measuring probe 412. The upper end of the temperature measuring probe 412 is fitted with a sealing sleeve 411 that matches the temperature measuring hole 9. The temperature measuring probe 412 extends from the temperature measuring hole 9 into the transformer body 1, so that the internal heat changes the resistance value inside the temperature measuring probe 412, thereby playing the role of measuring the internal temperature of the transformer body 1.
[0026] During operation, the operator can screw the capped bolt into the female mounting hole 10 through the female mounting hole 13 to install the mounting base 3 on the upper side of the transformer body 1, and then fix the temperature measuring component in the fixing groove 11 of the mounting base 3.
[0027] According to different transformer bodies 1, the staff can attach the temperature measuring strip 5 to the appropriate position using the magnetic strip 17. The temperature measuring strip 5 can measure the temperature of different positions on the outer end of the transformer body 1 through multiple sets of temperature measuring patches 16 and take the average value. When the temperature measuring patch 16 comes into contact with the position where the temperature needs to be measured, the heat will be transferred to the thermistor material inside the temperature measuring patch 16 through heat conduction, causing the resistance value to change so as to calculate the temperature.
[0028] Temperature probe 412 extends from temperature measuring hole 9 into the interior of transformer body 1, causing internal heat to change the internal resistance value of temperature probe 412, thereby achieving the function of measuring the internal temperature of transformer body 1.
[0029] When the temperature exceeds the set threshold, the control module 406 can collect the temperature measurement data through the temperature measurement module 408, and then control the multi-segment warning light 2 to flash in multiple segments, thereby providing the staff with an intuitive warning.
[0030] Through the above steps, this application combines a multi-segment warning light 2, a temperature measuring component, and a temperature measuring strip 5. When the transformer body 1 is working, the temperature measuring component can calculate the temperature by measuring the resistance changes of the temperature measuring probe 412 and the temperature measuring absorber through the temperature measuring module 408, and collect the temperature changes of the transformer body 1 and its surface. When the temperature exceeds the set threshold, the control module 406 controls the multi-segment warning light 2 to flash in multiple segments, thereby providing an intuitive warning to the staff. The data is transmitted to the terminal through the wireless module 407, so that the staff can remotely receive the temperature warning on the mobile phone, computer, or other terminals. This allows the staff to take timely measures to handle and repair when there are significant changes in the transformer temperature, reducing the probability of safety hazards and accidents in the transformer.
