Description

Technical Field

[0001] This utility model relates to the field of box-type transformer technology, and in particular to a temperature control and alarm device for box-type transformers. Background Technology

[0002] A box-type transformer, also known as a prefabricated substation or simply a box-type transformer, is a power facility that integrates a traditional transformer and its supporting equipment into a closed box. The dry-type transformer enclosed inside the box needs to be tested and monitored in a timely manner to ensure proper internal operating temperature.

[0003] The existing announcement number CN223022746U, entitled "An Alarm and Monitoring Device for Preventing Transformer Overheating," includes: a monitoring control box with a door on its front, a button on the front of the door, and a mounting groove on the bottom of the door; an audible and visual alarm mounted on the top of the monitoring control box; and an adjustment structure on the top of the monitoring control box, including a fixing ring fixedly mounted on the top of the monitoring control box, with a rotating ring movably mounted on the outer wall of the fixing ring via a bearing. This invention, by incorporating side and top reflectors, reflects sound and light to direct alarm signals in one direction, facilitating timely response from users located below the monitoring control box. Furthermore, the top reflector shields the audible and visual alarm from dust, preventing dust accumulation and ensuring a better user experience.

[0004] However, the aforementioned temperature control and detection components for the box-type transformer are fixed in a single position within the enclosure, resulting in temperature detection only at a single location inside the enclosure. This leads to limited internal temperature data and an inability to promptly display overall temperature changes within the transformer, resulting in inaccurate temperature control and detection. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a temperature control and alarm device for box-type transformers.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a temperature control and alarm device for a box-type transformer, comprising a box, temperature measuring elements, and warning elements. A dry-type transformer is installed inside the box, and two temperature measuring elements are symmetrically arranged on both sides of the box. The temperature measuring elements include a sliding frame, a vertical frame, and a lifting slider. The sliding frame is horizontally fixed to the bottom surface inside the box, and a vertical frame is vertically arranged on the top surface of the sliding frame. The vertical frame is horizontally slidably assembled on the sliding frame, and a lifting slider is vertically slidably assembled on the vertical frame. An electric telescopic rod is horizontally fixed on the lifting slider, and a support is vertically fixed at the output end of the electric telescopic rod. A temperature sensor is vertically fixed on the support. The warning elements include a tray, which is horizontally fixed to the top of the front face of the box, and a processor is horizontally fixed on the top surface of the tray. Warning lights are vertically fixed on both sides of the tray.

[0007] As a preferred embodiment, the processor's output is electrically connected to the warning light, and the processor's input is electrically connected to the temperature sensor.

[0008] As a preferred embodiment, a wireless signal transmitter is horizontally fixed on the top surface of the processor, and the output of the processor is electrically connected to the wireless signal transmitter.

[0009] As a preferred embodiment, the inside of the translation slide is horizontally rotatably connected to a translation screw, and the end of the translation slide is horizontally fixed to a translation motor, with the output end of the translation motor fixed to the end of the translation screw.

[0010] As a preferred embodiment, the bottom end face of the vertical slide frame has a screw hole slide plate, and the screw hole slide plate is horizontally slidably connected to the translation slide frame, and the screw hole slide plate and the translation screw are threadedly connected and assembled.

[0011] As a preferred embodiment, a lifting motor is vertically fixed on the top surface of the vertical sliding frame, and a lifting screw is vertically fixed at the output end of the lifting motor.

[0012] As a preferred embodiment, a screw cylinder is horizontally fixed on the lifting slider, and the screw cylinder and the lifting screw are threadedly connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When measuring the internal temperature of the enclosure, a temperature sensor detects the enclosure temperature data, which is then transmitted to a processor for processing. The processed data is then used to control whether the warning light is powered on and whether it illuminates to issue a warning. Simultaneously, to ensure comprehensive internal temperature detection, a vertical sliding frame slides horizontally within a horizontal sliding frame to adjust the temperature detection position of the dry-type transformer. Then, a lifting slider slides vertically within a vertical sliding frame to adjust the vertical height position for detecting the temperature of the dry-type transformer. Finally, the electric telescopic rod on the lifting slider extends, causing the temperature sensor to move horizontally to switch the temperature detection position of the dry-type transformer. This allows for the detection of more internal temperature data points of the enclosure transformer, enabling timely display of overall internal temperature changes and improving the accuracy of temperature control detection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0024] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] like Figures 1 to 5As shown, a temperature control and alarm device for a box-type transformer includes a box body 1, temperature measuring elements 2, and an alarm element 3. A dry-type transformer is installed inside the box body 1, and two temperature measuring elements 2 are symmetrically arranged on both sides of the box body 1. Each temperature measuring element 2 includes a sliding frame 21, a vertical sliding frame 24, and a lifting slider 28. The sliding frame 21 is horizontally fixed to the bottom surface of the box body 1, and the vertical sliding frame 24 is vertically arranged on the top surface of the sliding frame 21. The vertical sliding frame 24 is horizontally slidably assembled onto the sliding frame 21, and the lifting slider 28 is vertically slidably assembled onto the vertical sliding frame 24. An electric telescopic rod 282 is horizontally fixed to the lifting slider 28, and a support 283 is vertically fixed to the output end of the electric telescopic rod 282. A temperature sensor 284 is vertically fixed to the support 283. The alarm element 3 includes a tray 31, which is horizontally fixed to the top of the front end face of the box body 1, and a processor 32 is horizontally fixed to the top surface of the tray 31. Both sides of the enclosure are vertically fixed with warning lights 34. During use, when measuring the internal temperature of the enclosure 1, the temperature sensor 284 detects the enclosure temperature data. The data is transmitted to the processor 32 for processing. The processed data then controls whether the warning lights 34 are powered on and whether they illuminate to issue a warning. At the same time, to ensure the comprehensiveness of the internal temperature detection of the enclosure 1, the vertical slide frame 24 is activated to slide horizontally in the translation slide frame 21, adjusting the temperature detection position of the dry-type transformer. Then, the lifting slider 28 is activated to slide vertically in the vertical slide frame 24, adjusting the temperature detection height position of the dry-type transformer. Then, the electric telescopic rod 282 on the lifting slider 28 is activated to extend, driving the temperature sensor 284 to move horizontally to switch the temperature detection position of the dry-type transformer. This allows for the detection of more internal temperature data positions of the enclosure transformer, enabling timely display of the overall internal temperature changes of the enclosure transformer and improving the accuracy of temperature control detection of the enclosure transformer.

[0027] In one embodiment, such as Figure 2 and 5 As shown, the output of processor 32 is electrically connected to warning light 34, the input of processor 32 is electrically connected to temperature sensor 284, and a wireless signal transmitter 33 is horizontally fixed on the top surface of processor 32, with the output of processor 32 electrically connected to wireless signal transmitter 33. In use, processor 32, model STC89C51, processes the data transmitted from temperature sensor 284, and wireless signal transmitter 33, model CC1101, manufactured by Vankesheng, transmits the temperature data to the background for processing.

[0028] In one embodiment, such as Figure 2 and 3As shown, a translation screw 22 is horizontally rotatably connected inside the translation slide frame 21, and a translation motor 23 is horizontally fixed at the end of the translation slide frame 21. The output end of the translation motor 23 is fixed at the end of the translation screw 22. A screw hole slide plate 25 is on the bottom end face of the vertical slide frame 24, and the screw hole slide plate 25 is horizontally slidably connected in the translation slide frame 21. The screw hole slide plate 25 and the translation screw 22 are threaded through and assembled. A lifting motor 26 is vertically fixed on the top surface of the vertical slide frame 24, and a lifting screw 27 is vertically fixed at the output end of the lifting motor 26. A screw cylinder 281 is horizontally fixed on the lifting slider 28, and the screw cylinder 281 is threadedly connected to the lifting screw 27. During use, the translation motor 23 is started to drive the translation screw 22 to rotate. The rotating translation screw 22 drives the screw hole slide plate 25 on the bottom surface of the vertical slide frame 24 to move laterally in the translation slide frame 21, switching the temperature acquisition position along the X-axis. The lifting motor 26 on the top surface of the vertical slide frame 24 is started to drive the lifting screw 27 to rotate. The lifting screw 27 drives the screw cylinder 281 on the lifting slider 28 to vertically switch the temperature acquisition position along the Z-axis. The electric telescopic rod 282 on the lifting slider 28 is started to extend, driving the temperature sensor 284 to move laterally along the Y-axis to detect and switch the temperature position of the dry-type transformer.

[0029] In this embodiment, when measuring the internal temperature of the enclosure 1, the temperature sensor 284 detects the enclosure temperature data. The data is transmitted to the processor 32 for processing. The processed data then controls whether the warning light 34 is powered on and whether it illuminates to issue a warning. To ensure the comprehensiveness of the internal temperature detection of the enclosure 1, the translation motor 23 is started to drive the translation screw 22 to rotate. The rotating translation screw 22 drives the screw hole slide plate 25 on the bottom surface of the vertical slide frame 24 to move laterally in the translation slide frame 21, switching the temperature acquisition position along the X-axis. The lifting motor 26 on the top surface of the vertical slide frame 24 is started to drive the lifting screw 27 to rotate. The lifting screw 27 drives the screw cylinder 281 on the lifting slider 28 to vertically switch the temperature acquisition position along the Z-axis. The electric telescopic rod 282 on the lifting slider 28 is started to extend, driving the temperature sensor 284 to move laterally along the Y-axis to detect and switch the temperature position of the dry-type transformer.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
