Description

Technical Field

[0001] This invention belongs to the field of electrical equipment monitoring technology, specifically a reflective temperature-changing label. Background Technology

[0002] Electrical equipment in a power system refers to devices such as generators, transformers, power lines, and circuit breakers. The vital role of electricity in our lives and production cannot be ignored; it brings us immense convenience and is a crucial energy source. Power plants, ensuring the normal operation and transmission of electricity, as well as the reception of electrical energy in power-consuming areas, all require the use of electrical equipment to perform their respective tasks.

[0003] Overload overheating is a common problem in electrical systems, causing overheating in wire connection areas, terminal connection areas, etc., leading to circuit failures. Generally, when installing electrical equipment and wiring in an electrical system, to reduce the adverse effects of wire overheating, the appropriate wires are selected based on the actual conditions of the electrical equipment, the maximum load on the wires is calculated, the wire load is controlled, and protective devices are implemented to monitor the operation of the electrical equipment in real time.

[0004] With the application of protective devices, the system will automatically alarm in the event of a fault in electrical equipment, and relevant personnel can then carry out emergency repairs based on the alerts. Company staff will regularly maintain the electrical equipment, cleaning debris and dust according to the maintenance plan, providing sufficient operating space, and ensuring that heat can be dissipated promptly. During this process, staff will also monitor and record temperatures, checking for any abnormally high temperatures during use, and taking measures to cool the equipment if necessary to prevent unnecessary losses due to overheating.

[0005] Electrical equipment forms numerous detachable joints when connected. When the system is powered on and the electrical equipment is running, the joints often overheat, leading to incorrect phase sequence connections when wires are connected. During routine or special inspections, it is difficult to detect the potential overheating of the joints in time by manual visual inspection, which can easily lead to insulation breakdown of the electrical equipment and seriously endanger its safety. Summary of the Invention

[0006] To overcome the shortcomings of existing electrical equipment, where overheating at equipment joints is difficult for routine or special inspections to detect, easily leading to insulation breakdown and seriously endangering equipment safety, this application provides a reflective temperature-sensitive label. By using reflective stickers and fixing components to fix the temperature-sensitive patch at the connection point of electrical equipment, it can reduce the occurrence rate of phase sequence errors during the wiring stage of electrical equipment and increase the probability of detecting abnormal equipment, eliminating serious potential faults in their infancy. At the same time, when the circuit is overloaded, the temperature-sensitive patch at the connection point of the electrical equipment will change color, making it easier for inspection personnel to find abnormalities, ensuring personal and equipment safety, and improving power supply reliability.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A reflective temperature-sensitive label comprises two parts: a temperature-sensitive patch and a fixing assembly. The temperature-sensitive patch is fixed at the connection point of an electrical equipment connector and is used to monitor the overload temperature in that area.

[0009] The mounting assembly is used to install the temperature-sensing patch onto the electrical equipment connector for temperature monitoring in the installation area.

[0010] The fixing component includes multiple parts that can switch between plate-shaped and tubular states. A reflective sticker is provided on one side of the fixing component, and a temperature-sensing patch is located at the center of one side of the reflective sticker.

[0011] In one possible implementation, the temperature-sensing patch includes a display area, a temperature-sensing color-changing area is provided at the center of the display area, temperature indication characters are processed on the bottom surface of the display area, and adhesive is applied to the surface of the display area away from the temperature-sensing color-changing area, so that one side of the temperature-sensing patch is bonded to the surface at the center of the reflective sticker.

[0012] In one possible implementation, the temperature-sensing patches are configured in multiple ways, with one side of each temperature-sensing patch being adhesively connected to release paper, so that the multiple temperature-sensing patches are arranged in a matrix on the surface of the release paper.

[0013] In one possible implementation, the surface of the reflective sticker near the temperature-sensing patch is coated with reflective paint. There are multiple types of reflective stickers, and the reflective paint on the multiple reflective stickers is different in color, which is used to match the color of the wire sheath in the installation area of ​​the electrical equipment.

[0014] In one possible implementation, a protective film is provided on one side of the reflective sticker, and a temperature-sensitive patch is attached to the center of one side of the reflective sticker between the reflective sticker and the protective film. The protective film is made of transparent plastic material, and one side of the protective film is attached to the surface of the reflective sticker and covers the outside of the temperature-sensitive patch.

[0015] In one possible implementation, the fixing component includes multiple support bars, with second fixing bars on both sides of the multiple support bars, and first fixing bars on one side of each of the two second fixing bars. The multiple support bars are divided into two groups, each group containing the same number of support bars, and a heat-conducting strip is provided between the two groups. The two first fixing bars, two second fixing bars, multiple support bars, and one heat-conducting strip are arranged in a straight line.

[0016] In one possible implementation, the top and bottom surfaces of the first fixing strip, the second fixing strip, the support strip, and the heat-conducting strip are all machined with first storage grooves. Connecting strips are provided inside the multiple first storage grooves. The first storage grooves located at the same height are interconnected and are in a straight line. The connecting strips are simultaneously fixed to the first fixing strip, the second fixing strip, the support strip, and the heat-conducting strip by multiple screws.

[0017] In one possible implementation, a second storage groove is machined at the center of one side of the heat-conducting strip, and a first magnet is embedded inside the second storage groove. The first magnet is located on the opposite side of the temperature-sensing patch. The depth of the first storage groove is greater than the thickness of the connecting strip, and multiple screw heads used to fix the connecting strip are all stored inside the first storage groove.

[0018] In one possible implementation, a third storage groove is machined at the center of one side of both the first and second fixing strips. A second magnet is embedded in the interior of the third storage groove. The second magnet is located on the opposite side of the first magnet. When the second magnets on the two second fixing strips on both sides attract each other, the surfaces of the two second fixing strips on the side away from the second magnet are put together. The second magnets on the two first fixing strips on both sides attract each other, so that the surfaces of the two first fixing strips on the opposite side of the second magnet are put together.

[0019] In one possible implementation, the width of the first fixing strip is greater than the width of the second fixing strip, the width of the second fixing strip is greater than the width of the support strip, and the two first fixing strips are located outside the two second fixing strips.

[0020] The beneficial effects of this application are as follows:

[0021] First, in this solution, by using reflective stickers and fixing components to fix the temperature-sensing patch at the connection point of electrical equipment, the occurrence rate of phase sequence errors can be reduced during the wiring stage of electrical equipment, and the probability of abnormal equipment can be increased, eliminating serious potential faults in their infancy. At the same time, when the circuit is overloaded, the temperature-sensing patch at the connection point of electrical equipment will change color, making it easier for inspection personnel to find abnormal points, ensuring personal and equipment safety, and improving power supply reliability.

[0022] Secondly, in this solution, by using reflective stickers to attach to the wires, the temperature-sensing patch is directly fixed to the outside of the wire connection point, which can prevent the temperature-sensing patch from sliding on the outside of the wires and enable stable temperature monitoring in this area.

[0023] Thirdly, in this solution, the fixing component is formed into a ring by using the second magnets on both sides of the fixing component to attract each other, and is fixed on the outside of the metal connector of the electrical equipment. It is also fixed by the second magnet and the first magnet. Alternatively, the fixing component can be fixed at the larger connector of the electrical equipment by using the second magnets on both sides and the first magnet. This solution is highly flexible and has a good fixing effect.

[0024] Fourth, in this solution, by setting up multiple types of reflective stickers, each with a different color of reflective paint sprayed on its surface, when the reflective sticker with the temperature-sensitive patch is fixed to the outside of the wire, it can match the color of the wire sheath in the installation area of ​​the electrical equipment, making up for the defect that the color on the sheath cannot be identified after the wire ages, and ensuring normal judgment during the inspection process.

[0040] This application provides a modified solid powder crosslinking profile control agent production equipment. By using reflective stickers and fixing components to fix temperature-sensitive patches at the connection points of electrical equipment, it can reduce the occurrence rate of phase sequence errors during the wiring stage of electrical equipment and increase the probability of detecting abnormal equipment, eliminating serious potential faults in their infancy. At the same time, when the circuit is overloaded, the temperature-sensitive patches at the connection points of electrical equipment will change color, solving the problem that overheating of equipment joints during operation is difficult to be detected by personnel during routine or special inspections, which can easily lead to insulation breakdown of electrical equipment and seriously endanger the safety of electrical equipment.

[0041] Meanwhile, by setting the fixing component in the form of a combination of two first fixing strips, two second fixing strips, multiple support strips and a heat-conducting strip, and using two connecting strips to complete the connection of each part, the reflective sticker is attached to the surface of the fixing component by pasting. It can be attracted to each other by the second magnets on both sides of the fixing component, so that the fixing component forms a ring and is fixed to the outside of the metal joint of the electrical equipment. It can also be fixed by the second magnet and the first magnet. It can also be fixed to the larger joint of the electrical equipment by the second magnet on both sides and the first magnet, so as to ensure that the fixing component can fix the reflective sticker with the temperature-sensing patch to various types of connection points of the electrical equipment.

[0042] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0043] Example 1:

[0044] This embodiment describes the specific structure of a reflective thermochromic label, please refer to the following for details. Figures 1-9 As shown, it includes a temperature-sensitive patch 2 and a fixing component 3. The temperature-sensitive patch 2 includes a marking display area 202. A temperature-sensitive color-changing area 201 is provided at the center of the surface of the marking display area 202. A reflective sticker 4 is provided on one side of the fixing component 3. The temperature-sensitive patch 2 is located at the center of one side of the reflective sticker 4.

[0045] Temperature indicator characters are machined on the bottom surface of the display area 202, and adhesive is applied to the side of the display area 202 away from the temperature-sensing color-changing area 201. When one side of the temperature-sensing patch 2 is pasted to the center surface of the reflective sticker 4, the temperature-sensing patch 2 can be used to directly detect whether there is a current overload in the area after the reflective sticker 4 is fixed to the electrical equipment connector, causing the temperature to rise.

[0046] In some examples, the temperature-sensing patch 2 is configured in multiple ways. By attaching a release paper 1 to one side of multiple temperature-sensing patches 2, the multiple temperature-sensing patches 2 are arranged in a matrix on the surface of the release paper 1, which makes it convenient to use multiple temperature-sensing patches 2 as spares.

[0047] Meanwhile, when the temperature-sensing patch 2 is needed, it can be simply peeled off from the surface of the release paper 1. When the temperature-sensing patch 2 is pasted on the surface of the reflective sticker 4 and the reflective sticker 4 is installed at the connection point of the electrical equipment, the temperature-sensing patch 2 can monitor the current overload temperature in that area.

[0048] Secondly, the reflective sticker 4 with the temperature-sensing patch 2 is pasted on the surface of the fixing component 3. The fixing component 3 can be used to install the temperature-sensing patch 2 to the electrical equipment connector for temperature monitoring in the installation area.

[0049] Furthermore, there are multiple types of reflective stickers 4. The surface of the reflective sticker 4 near the temperature-sensing patch 2 is sprayed with reflective paint, so that the surface color of the reflective sticker 4 can be seen in a sufficiently bright environment. The reflective paint on multiple reflective stickers 4 is different in color. When the reflective sticker 4 with the temperature-sensing patch 2 is fixed to the outside of the wire, it can match the color of the wire sheath in the installation area of ​​the electrical equipment, making up for the defect that the color on the sheath cannot be identified after the wire ages.

[0050] Furthermore, a protective film 5 is provided on one side of the reflective sticker 4. The temperature-sensing patch 2, which is pasted at the center of one side of the reflective sticker 4, is located between the reflective sticker 4 and the protective film 5. By using transparent plastic material to make the protective film 5, after pasting one side of the protective film 5 to the surface of the reflective sticker 4 to cover the outside of the temperature-sensing patch 2, the protective film 5 can protect the temperature-sensing patch 2 and improve the accuracy of temperature monitoring by the temperature-sensing patch 2.

[0051] By adopting the above technical solution:

[0052] The above design involves attaching a temperature-sensing patch 2 to one side of the reflective sticker 4 and covering one side of the temperature-sensing patch 2 with a protective film 5. When the protective film 5 is attached to the reflective sticker 4, the temperature-sensing patch 2 can be protected. When the reflective sticker 4 is fixed to the outside of the electrical equipment connection point by the fixing component 3 or directly attached to the electrical equipment connection point and wire connection point, the temperature-sensing patch 2 in the prior art can be used to monitor the temperature rise of the target area due to current overload. When the temperature is too high, the temperature-sensing color display area 201 on the temperature-sensing patch 2 will change color and display the over-temperature number on the temperature-sensing patch. This makes it convenient for staff to intuitively see whether the circuit is overloaded during the inspection process, which is beneficial for protecting electrical equipment.

[0053] Meanwhile, during the electrical equipment wiring stage, the temperature sensing patch 2 can be used to determine whether the current overload caused by incorrect phase sequence connection will cause the component to heat up and change color, which is helpful to judge whether the phase sequence is incorrect and reduce the probability of incorrect phase sequence connection.

[0054] In addition, by setting the reflective sticker 4 to multiple types, with different reflective paint colors sprayed on the surface of each reflective sticker 4, when the reflective sticker 4 with the temperature-sensing patch 2 is fixed to the outside of the wire, it can match the color of the wire sheath in the installation area of ​​the electrical equipment, making up for the defect that the color on the sheath cannot be identified after the wire ages, and ensuring that the phase sequence can be judged normally during the inspection.

[0055] Example 2:

[0056] Based on Embodiment 1, this embodiment describes the specific structure of the fixing component 3. The fixing component 3 includes multiple support bars 304. Second fixing bars 305 are provided on both sides of the multiple support bars 304. First fixing bars 302 are provided on one side of each of the two second fixing bars 305. The multiple support bars 304 are divided into two groups, and each group contains the same number of support bars 304. A heat-conducting strip 309 is provided between the two groups.

[0057] The top and bottom surfaces of the first fixing strip 302, the second fixing strip 305, the support strip 304, and the heat-conducting strip 309 are all machined with first storage grooves 306. Connecting strips 301 are provided inside the multiple first storage grooves 306. The first storage grooves 306 at the same height are interconnected and form a straight line. The connecting strips 301 are fixed to the first fixing strip 302, the second fixing strip 305, the support strip 304, and the heat-conducting strip 309 simultaneously by multiple screws. This allows two first fixing strips 302, two second fixing strips 305, multiple support strips 304, and one heat-conducting strip 309 to be connected together and arranged in a straight line.

[0058] Meanwhile, the width of the first fixing strip 302 is greater than the width of the second fixing strip 305, and the width of the second fixing strip 305 is greater than the width of the support strip 304. The two first fixing strips 302 are located outside the two second fixing strips 305. When using the fixing component 3 to fix the reflective sticker 4 to the target area, the fixing component 3 can switch between plate-shaped and tubular states.

[0059] Secondly, a second storage groove 307 is machined at the center of one side of the heat-conducting strip 309. A first magnet 303 is embedded inside the second storage groove 307. The first magnet 303 is located on the opposite side of the temperature-sensing patch 2. In order to fix the reflective sticker 4 to the target area after the fixing component 3 fixes it, so that the temperature-sensing patch 2 can stably monitor the temperature at that location, the groove depth of the first storage groove 306 is greater than the thickness of the connecting strip 301. This ensures that the multiple screw heads used to fix the connecting strip 301 are all stored inside the first storage groove 306, and prevents the screws from blocking the first magnet 303 from adsorbing with the target metal.

[0060] Meanwhile, when the target position cannot be attracted by the first magnet 303, the use of the fixing component 3 is cancelled, and the reflective sticker 4 is directly pasted at the position so that the temperature-sensing patch 2 can perform temperature monitoring.

[0061] Furthermore, a third storage groove 310 is machined at the center of one side of the first fixing strip 302 and the second fixing strip 305. A second magnet 308 is embedded in the interior of the third storage groove 310. When the second magnet 308 is located on the opposite side of the first magnet 303, the second magnets 308 on the two second fixing strips 305 on both sides attract each other, and the surfaces of the two second fixing strips 305 away from the second magnet 308 are in contact. When the second magnets 308 on the two first fixing strips 302 on both sides attract each other, the surfaces of the two first fixing strips 302 on the opposite side of the second magnet 308 are in contact.

[0062] Meanwhile, the surface of one first fixing strip 302 away from the temperature-sensing patch 2 can overlap the surface of another first fixing strip 302 or second fixing strip 305 near the temperature-sensing patch 2, and they can be attracted to each other by means of the second magnet 308, so that the fixing component 3 can be formed into a tube shape to accommodate flat connectors and cylindrical connectors.

[0063] The specific operating steps are as follows:

[0064] Scenario 1:

[0065] S1. If the installation position of the temperature sensing patch 2 is a wire connector, select a reflective sticker 4 with the same surface color as the wire, peel the temperature sensing patch 2 off the surface of the release paper 1, and stick it in the center of the non-adhesive side of the reflective sticker 4.

[0066] S2. Adhere the protective film 5 to the center of the non-adhesive side of the reflective sticker 4, so that the protective film 5 covers the surface of the temperature-sensing patch 2 and protects the temperature-sensing patch 2.

[0067] S3. Attach the adhesive side of the reflective sticker 4 to the outside of the wire connection area so that the temperature-sensing patch 2 can monitor the temperature of that area.

[0068] Scenario 2:

[0069] S1. If the installation position of the temperature sensing patch 2 is the metal plate joint of the electrical equipment, peel the temperature sensing patch 2 off the surface of the release paper 1 and stick it to the center of the non-adhesive side of the reflective sticker 4 of any color.

[0070] S2. Adhere the protective film 5 to the center of the non-adhesive side of the reflective sticker 4, so that the protective film 5 covers the surface of the temperature-sensing patch 2 and protects the temperature-sensing patch 2.

[0071] S3. The adhesive side of the reflective sticker 4 is pasted onto the surface of the fixing component 3. The second magnet 308 inside the first fixing strip 302 and the second fixing strip 305, and the first magnet 303 inside the heat-conducting strip 309 are attracted to the metal plate, thereby fixing the fixing component 3 at this position. The first magnet 303 can make the heat-conducting strip 309 stick to the metal plate, so that the temperature-sensing patch 2 can stably monitor the temperature of the area.

[0072] Scenario 3:

[0073] S1. If the installation position of the temperature sensing patch 2 is a plate-shaped joint or cylindrical joint of an electrical device, and the joint is strip-shaped, peel the temperature sensing patch 2 off the surface of the release paper 1 and stick it to the center of the non-stick surface of the reflective sticker 4 of any color.

[0074] S2. Adhere the protective film 5 to the center of the non-adhesive side of the reflective sticker 4, so that the protective film 5 covers the surface of the temperature-sensing patch 2 and protects the temperature-sensing patch 2.

[0075] S3. Adhere the adhesive side of the reflective sticker 4 to the surface of the fixing component 3, so that the fixing component 3 surrounds the outside of the plate-shaped joint or the cylindrical joint, so that the second magnets 308 on the two second fixing strips 305 on both sides attract each other, or the second magnets 308 on the two first fixing strips 302 on both sides attract each other, and the surface of one first fixing strip 302 away from the temperature-sensing patch 2 can overlap the surface of another first fixing strip 302 or second fixing strip 305 near the temperature-sensing patch 2, and attract each other through the second magnets 308, so that the temperature-sensing patch 2 can stably monitor the temperature of the area.

[0076] By adopting the above technical solution:

[0077] The above design sets the fixing component 3 in the form of a combination of two first fixing strips 302, two second fixing strips 305, multiple support strips 304 and a heat-conducting strip 309, and uses two connecting strips 301 to complete the connection of each part, while one side of the reflective sticker 4 is connected to the surface of the fixing component 3 by pasting.

[0078] In actual installation, the temperature-sensing patch 2 can be directly fixed to the outside of the wire connection point using reflective sticker 4 to prevent it from sliding on the outside of the wire. Alternatively, the second magnets 308 on both sides can attract each other to form a ring shape, which is then fixed to the outside of the metal connector of the electrical equipment. The second magnets 308 and the first magnet 303 can be used to fix the fixing component 3 to the larger connector of the electrical equipment. This method offers high flexibility, is less affected by dust and water, can be fixed for a long time, and because the magnetic failure temperature is high, there will be no situation where the circuit current overload causes the line temperature to become too high, causing the magnet to fail and the fixing component 3 to detach from the fixing area.

[0079] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
