Description

Technical Field

[0001] This application relates to the field of temperature monitoring technology, and more specifically, to a multi-point temperature acquisition and monitoring device for substations. Background Technology

[0002] A substation is an assembly of equipment used to disconnect or connect, change or adjust voltage. In a power system, a substation is the junction point for power transmission and distribution. Substations are mainly divided into: step-up substations, main grid substations, secondary substations, and distribution substations. There are also prefabricated substations.

[0003] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer voltage reduction and low-voltage power distribution, and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box.

[0004] Currently, the widespread use of prefabricated substations and cable lines in urban construction worldwide, coupled with the rapid increase in power load, has led to overheating of some power equipment and cable heads, which could result in equipment burnout.

[0005] Traditional substation temperature measurement mainly uses equipment such as temperature testing wax strips and infrared thermometers to detect electrical equipment in the substation. This method requires staff to conduct regular inspections, which has the problem of low inspection efficiency. It not only increases the workload of operation and maintenance personnel, but also makes it easy for data collection to be untimely if only operation and maintenance personnel conduct regular inspections.

[0006] Moreover, this type of inspection can only serve as an early warning when maintenance personnel conduct power inspections. Without inspection, staff cannot accurately know the temperature inside the box-type substation, which poses certain safety hazards. Its real-time performance and accuracy are both low.

[0007] Meanwhile, this risk is difficult to control. Therefore, in order to solve the above-mentioned problems, a multi-point temperature acquisition and monitoring device was designed. Without affecting the normal operation of the electrical equipment being tested, and without affecting the workers' inspection and maintenance, it also solves the problem of the entire electrical equipment being powered off due to maintenance of the temperature measuring equipment. Ultimately, it can monitor the temperature of the power equipment in the box-type transformer in real time and efficiently. Summary of the Invention

By improving the actual monitoring effect, flexibility, and self-regulation performance of temperature acquisition and monitoring, and by providing strong temperature monitoring capabilities, it enables real-time monitoring and temperature control of electrical equipment inside prefabricated transformers. This reduces the workload of staff and allows maintenance personnel to promptly understand the real-time temperature information of equipment within the prefabricated substation.

[0023] According to the substation multi-point temperature acquisition and monitoring device of the present application embodiment, both the front and rear ends of the sliding member surface are connected to sliders.

[0024] In one embodiment of this application, the substation multi-point temperature acquisition and monitoring device further includes:

[0025] Adjustment fitting, which includes an adjustment motor and a main connecting pipe, wherein the main connecting pipe is located on the rear side of the adjustment motor;

[0030] According to the substation multi-point temperature acquisition and monitoring device of the present application embodiment, a supporting ring plate is provided on the rear side of the ring plate, and an air suction pump is embedded in the front surface of the supporting ring plate.

[0032] According to the substation multi-point temperature acquisition and monitoring device of the present application embodiment, the surface of the support ring plate is respectively provided with a first bearing groove and a second bearing groove.

[0033] The beneficial effects of this invention are:

[0034] 1. With the combined action of the auxiliary support, the upper stabilizer, and the second auxiliary stabilizer, this device can increase the stability of the connecting parts when they move. By adding the first auxiliary stabilizer, the stability of the connecting plate can be further enhanced. The screw can adjust the position of the connecting parts. Under the action of the fixed shell and the sliding parts, the actual positions of the adjusting parts, the heating components, and the temperature measuring components can be adjusted, increasing its flexibility.

[0035] 2. This device adjusts the position of the connecting parts through the drive unit, screw unit, and screw plate, enabling the thermal imaging sensor to perform large-area thermal imaging temperature acquisition of electrical components within the prefabricated substation, determining the heat source temperature of the electrical components. Simultaneously, in conjunction with the wireless temperature measuring device, it can perform multi-point real-time acquisition and monitoring of the temperature of the overall components and critical electrical components within the electrical system, forming a complete main temperature acquisition system. This facilitates subsequent rapid identification and maintenance of high-heat sources in critical electrical equipment by staff.

[0036] 3. This device uses thermal imaging sensors to collect and monitor the overall heat sources of electrical components. It also uses a suction pump to collect air from the heat sources of electrical components around the main connecting pipes. This allows for the collection and monitoring of multiple heat sources in the electrical components and auxiliary parts. Subsequent algorithms can then be used to create a complete auxiliary temperature acquisition system, reducing the practical cost of temperature sensing equipment. Through the coordinated use of temperature sensors, adjustment components, and temperature measurement modules, the device can ultimately collect the overall temperature of electrical components within the prefabricated substation, forming a comprehensive temperature acquisition and monitoring scheme. This allows for timely and effective collection and monitoring of all working heat-generating components within the electrical system, increasing the flexibility and accuracy of temperature detection within the electrical components.

[0037] In summary, when collecting and monitoring temperature data in electrical components within a prefabricated substation in real time, operators can first use thermal imaging sensors to measure the overall temperature within the components. This temperature data is then transmitted wirelessly to a display device operated by maintenance personnel for observation and monitoring. Multiple thermal imaging sensors can be used; when the drive unit operates, it rotates the screw mechanism, which in turn moves the screw plate, thus moving the connecting parts and the thermal imaging sensors. This allows the thermal imaging sensors to obtain complete data on the electrical components within the prefabricated substation. Furthermore, the stabilizing element enhances the stability of the moving connecting parts.

[0038] When maintenance is performed on electrical components, staff only need to operate the drive unit to move the connector and thermal imaging sensor to a corner of the prefabricated substation. When maintaining the thermal imaging sensor, staff only need to remove the connector, increasing the flexibility of equipment maintenance.

[0039] During temperature measurement, due to the large number of electrical devices inside the prefabricated substation, in order to reduce operating costs, it is not possible to install temperature measuring devices on all electrical structures. Temperature acquisition devices can only be installed on key electrical parts. Therefore, it is not possible to effectively and accurately reflect the operating temperature information inside the prefabricated substation. Therefore, this problem needs to be solved.

[0040] First, the staff can install the fixed outer shell into a suitable position inside the box-type substation via the carrier plate. The movable sliding part can be used to adjust the position of the distribution motor. The wireless temperature measuring device in the first and second bearing grooves of the support ring plate is adjustable. The staff can rotate and remove the telescopic part to attach multiple wireless temperature measuring devices to key parts inside the electrical components, such as the high and low voltage leads of the main transformer, the connection points of important load equipment, cable terminals, voltage transformers, etc., to perform real-time contact temperature measurement. The wireless temperature measuring device is movably connected to the damping universal joint of the telescopic part through the outer protective part, which can flexibly adjust the angle of the wireless temperature measuring device. The telescopic part has the ability to extend and adjust the position of the wireless temperature measuring device. The wireless temperature measuring device uses a wireless temperature sensor, which can prevent itself from affecting the equipment inside the electrical components due to the difficulty of managing the cable. At the same time, it has the characteristics of low cost, low power consumption, and high safety.

[0041] Multiple tension pipe fittings can be installed around various auxiliary components within the electrical components. By adjusting the operation of the motor, the ring plate and main connecting pipe fittings are rotated until the main connecting pipe fitting rotates and is in a connected and fitted state with the auxiliary connecting pipe fittings within it. The air pump can transfer heat from the air around the auxiliary electrical components to the main connecting pipe fittings through the tension pipe fittings. The temperature sensor can monitor and collect the temperature entering the main connecting pipe fitting. Both the main connecting pipe fitting and the tension pipe fittings are high-insulation pipes, which can reduce heat loss. The temperature data collected by the temperature sensor, after adding the heat loss, can ultimately determine the actual heat of the auxiliary components on the electrical components around the tension pipe fittings. At the same time, the position of the fixed shell can be flexibly adjusted, so as not to affect the subsequent operation and maintenance of the electrical components. Attached Figure Description

[0062] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] Example

[0065] like Figures 1-10 As shown, the substation multi-point temperature acquisition and monitoring device according to an embodiment of this application includes: a reciprocating drive 30, a temperature sensor 40, and a support assembly 50; the reciprocating drive 30 includes a slide 31 and a screw 32, the screw 32 being disposed in the inner cavity of the slide 31 for adjusting the position of the temperature sensor; the temperature sensor 40 includes a screw plate 42 and a thermal imaging sensor 45, the thermal imaging sensor 45 being disposed above the screw plate 42 for thermal imaging monitoring; the support assembly 50 includes a fixed housing 51 and a sliding member 52, the sliding member 52 being disposed in the inner cavity of the fixed housing 51.

[0066] like Figures 3-5 As shown, traditional substation temperature measurement mainly uses equipment such as temperature testing wax strips and infrared thermometers to detect electrical equipment in the substation. This method requires staff to conduct regular inspections, which has the problem of low inspection efficiency. It not only increases the workload of operation and maintenance personnel, but also makes it easy for data collection to be untimely if only operation and maintenance personnel conduct regular inspections.

[0067] Moreover, this type of inspection can only serve as an early warning when maintenance personnel conduct power inspections. Without inspection, staff cannot accurately know the temperature inside the box-type substation, which poses certain safety hazards. Its real-time performance and accuracy are both low.

[0068] Meanwhile, this risk is difficult to control. Therefore, in order to solve the above-mentioned problems, a multi-point temperature acquisition and monitoring device was designed. Without affecting the normal operation of the electrical equipment being tested, and without affecting the workers' inspection and maintenance, it also solves the problem of the entire electrical equipment being powered off due to maintenance of the temperature measuring equipment. Ultimately, it can monitor the temperature of the power equipment in the box-type transformer in real time and efficiently.

[0069] A box-type substation 10 is provided on one side of the reciprocating drive component 30, and an electrical component 20 is installed on the rear side of the inner cavity of the box-type substation 10. The slide table 31 is located on the front side of the bottom of the inner cavity of the box-type substation 10.

[0070] The top of the slide table 31 is provided with a sliding body 311, and the front surface of the slide table 31 is provided with a through groove 312; a driving component 321 is provided on the right side of the slide table 31.

[0071] For example, the left side of the drive member 321 is bolted to the right side of the slide table 31, the output end of the drive member 321 extends through the inner cavity of the slide table 31 and is connected to the surface of the screw member 32, and both ends of the surface of the screw member 32 are movably connected to the inner cavity of the slide table 31 through bearings.

[0072] An auxiliary support 33 is provided on the front side of the top of the inner cavity of the prefabricated substation 10, and an upper sliding body 331 is provided on the front side of the top of the auxiliary support 33.

[0073] For example, the rear side of the top of the auxiliary support 33 is connected to the top of the inner cavity of the box-type substation 10; the screw plate 42 is threaded onto the outer surface of the screw member 32.

[0074] A connecting plate 421 is connected to the front side of the screw plate 42, and a first auxiliary stabilizer 422 is slidably disposed on the surface of the connecting plate 421.

[0075] For example, the other end of the connecting plate 421 extends through to the outside of the through groove 312, and the two ends of the first auxiliary stabilizer 422 are connected to the two ends of the inner cavity of the box-type substation 10.

[0076] The top of the connecting plate 421 is connected to a support 43, and the top of the support 43 is provided with a connector 41;

[0077] For example, the thermal imaging sensor 45 is installed on both sides of the rear side of the connector 41, and there are several screw plates 42. The corresponding number of support 43, connector 41 and upper stabilizer 44 are also several, and multiple screw plates 42 are arranged on both sides of the screw member 32. The screw member 32 is a bidirectional lead screw.

[0078] The top of the connector 41 is provided with an upper stabilizer 44, and the surface of the upper stabilizer 44 is slidably connected to a second auxiliary stabilizer 441;

[0079] For example, to facilitate the disassembly of connector 41 and the installation and adjustment of thermal imaging sensor 45;

[0080] For example, the upper and lower sides of the connector 41 are connected to the upper stabilizer 44 and the support 43 in a movable manner, such as by snap-fit ​​or movable screw connection. This solution does not limit the connection method of the connector 41 to the upper stabilizer 44 and the support 43 respectively.

[0081] For example, the two ends of the second auxiliary stabilizer 441 are respectively connected to the two ends of the inner cavity of the box-type substation 10;

[0082] For example, rollers are installed on the surfaces of the support 43 and the upper stabilizer 44, and the bottoms of the rollers are slidably disposed in the inner cavities of the lower slide body 311 and the upper slide body 331, respectively.

[0083] There are several fixed housings 51. The fixed housings 51 and the sliding parts 52 are slidably connected. A carrier plate 512 is provided on the right side of the fixed housings 51.

[0084] For example, the fixed housing 51 is disposed on the front side of the inner cavity of the box-type substation 10.

[0087] When collecting and monitoring temperature data in electrical components 20 within the prefabricated substation 10 in real time, staff can first use thermal imaging sensors 45 to measure the overall temperature within electrical components 20 in real time. The obtained temperature data is then transmitted to the display device operated by maintenance personnel via an external wireless transmission device for observation and monitoring. Multiple thermal imaging sensors 45 can be used. When the drive unit 321 is working, it can drive the screw unit 32 to rotate. The rotation of the screw unit 32 can drive the screw plate 42 to slide, thereby moving the connecting part 41 and the thermal imaging sensors 45. This allows the thermal imaging sensors 45 to obtain complete data on the electrical components 20 within the prefabricated substation 10. Under the action of the upper stabilizing component 44, the stability of the connecting part 41 during movement is increased.

[0088] When maintenance is performed on the electrical components 20, the staff only needs to operate the drive component 321 to move the connecting component 41 and the thermal imaging sensor 45 to a corner position inside the box-type substation 10. When maintaining the thermal imaging sensor 45, the staff only needs to remove the connecting component 41, which increases the flexibility of equipment maintenance.

[0089] The substation multi-point temperature acquisition and monitoring device according to the embodiments of this application further includes: a regulating component 60, a heat extraction component 70, and a temperature measuring component 80; the regulating component 60 includes a regulating motor 61 and a main connecting pipe 63, the main connecting pipe 63 being disposed on the rear side of the regulating motor 61; the heat extraction component 70 includes an auxiliary connecting pipe 72 and a tensioning pipe 73, the tensioning pipe 73 being disposed on the rear side of the auxiliary connecting pipe 72; the temperature measuring component 80 includes a middle ring plate 81 and a telescopic component 83.

[0090] A connecting plate 611 is provided on the rear side of the adjusting part 60. Reinforcing arms 612 are provided at the four corners of the surface of the connecting plate 611. An annular groove 613 is provided on the rear side of the connecting plate 611.

[0091] For example, the connecting plate 611 and the adjusting part 60 are fastened together by screws, and the reinforcing arm 612 is welded to the side opposite to the connecting plate 611.

[0092] A ring plate 62 is provided on the rear side of the connecting plate 611. A ring block 621 is connected to the front surface of the ring plate 62. A venting cavity 622 is opened on the inner surface of the ring plate 62. A temperature sensor 64 is installed inside the main connecting pipe 63.

[0093] For example, the surface of the annular block 621 extends into the inner cavity of the annular groove 613 and is slidably connected to the connection of the annular groove 613, and the front end of the main connecting pipe 63 is installed at the rear end of the ring plate 62 and communicates with the venting cavity 622.

[0094] A support ring plate 71 is provided on the rear side of the ring plate 62, and an air suction pump 711 is inlaid on the front surface of the support ring plate 71.

[0095] For example, the reinforcing arm 612 is fixedly connected to the outside of the auxiliary connecting pipe 72. There are several auxiliary connecting pipes 72 and they are evenly distributed on the surface of the support ring plate 71. The tension pipe 73 and the auxiliary connecting pipe 72 are connected on opposite sides. The output end of the suction pump 711 is connected to the inner cavity of the ventilation chamber 622 through a pipe.

[0096] For example, both the auxiliary connecting pipe 72 and the main connecting pipe 63 have sealing rubber gaskets connected to their opposite sides.

[0097] The output end of the telescopic component 83 is provided with a wireless temperature measuring component 82, and the outer surface of the wireless temperature measuring component 82 is provided with an outer protective component 821. The surface of the support ring plate 71 is respectively provided with a first bearing groove 84 and a second bearing groove 841.

[0098] For example, the middle ring plate 81 and the telescopic member 83 are movably connected on opposite sides by a damping pivot, and the number of telescopic members 83 is several;

[0099] For example, the output end of the telescopic member 83 is movably connected to the outer protective member 821 via a damping universal joint;

[0100] For example, the wireless temperature measuring element 82 is disposed in the inner cavity of the first bearing groove 84, the middle ring plate 81 is fixedly installed at the center of the inner cavity of the second bearing groove 841, and the telescopic element 83 is disposed on the inner surface of the second bearing groove 841.

[0101] For example, the outer surfaces of the telescopic member 83 and the outer protective member 821 are both bonded with rubber pads for preventing detachment, and the surface of the rubber pads is in frictional contact with the inner walls of the first bearing groove 84 and the second bearing groove 841.

[0102] like Figure 6-10 As shown, during temperature measurement, due to the large number of electrical devices inside the prefabricated substation, in order to reduce the cost of use, it is not possible to install temperature measuring devices on all electrical structures. Temperature acquisition devices can only be installed on key electrical parts. Therefore, it is not possible to effectively and accurately reflect the operating temperature information inside the prefabricated substation. Therefore, this problem needs to be solved.

[0103] First, the staff can install the fixed outer shell 51 into a suitable position inside the box-type substation 10 via the carrier plate 512. The movable sliding part 52 can be used to adjust the position of the distribution motor 61. The wireless temperature measuring element 82 located in the first bearing groove 84 and the second bearing groove 841 in the support ring plate 71 is adjustable. The staff can rotate and remove the telescopic part 83 to attach multiple wireless temperature measuring elements 82 to key parts inside the electrical component 20, such as the high and low voltage leads of the main transformer, the connection points of important load equipment, cable terminals, voltage transformers, etc., to perform real-time contact temperature measurement. The wireless temperature measuring element 82 is movably connected to the damping universal joint of the telescopic part 83 through the outer protective part 821, which can flexibly adjust the angle of the wireless temperature measuring element 82. The telescopic part 83 has the ability to extend and can adjust the position of the wireless temperature measuring element 82. The wireless temperature measuring element 82 uses a wireless temperature sensor, which can prevent itself from affecting the equipment inside the electrical component 20 due to the difficulty in managing the cable. At the same time, it has the characteristics of low cost, low power consumption and high safety.

[0104] Multiple tension pipe fittings 73 can be installed around various auxiliary components within the electrical component 20. By adjusting the operation of the motor 61, the ring plate 62 and the main connecting pipe 63 are rotated until the main connecting pipe 63 rotates and is in a connected and fitted state with the auxiliary connecting pipe 72. The air pump 711 can transfer the heat in the air around the auxiliary electrical components of the electrical component 20 to the main connecting pipe 63 through the tension pipe fittings 73. The temperature sensor 64 can monitor and collect the temperature entering the main connecting pipe 63. Both the main connecting pipe 63 and the tension pipe fittings 73 are high-insulation pipes, which can reduce heat loss. The temperature data collected by the temperature sensor 64, after adding the heat loss, can finally determine the actual heat of the auxiliary components on the electrical component 20 around the tension pipe fittings 73. At the same time, the position of the fixed shell 51 can be flexibly adjusted so as not to affect the subsequent operation and maintenance of the electrical component 20.

[0105] Specifically, the working principle of the multi-point temperature acquisition and monitoring device in the substation is as follows: When collecting and monitoring the temperature data of the electrical components 20 in the box-type substation 10 in real time, the staff can first use the thermal imaging sensor 45 to measure the overall temperature of the electrical components 20 in real time, and transmit the obtained temperature data of the box-type substation 10 to the display device operated by the maintenance personnel through an external wireless transmission device, so that the maintenance personnel can observe and monitor it. There can be multiple sets of thermal imaging sensors 45. When the drive component 321 is working, it can drive the screw component 32 to rotate. The rotation of the screw component 32 can drive the screw plate 42 to slide, thereby moving the connecting component 41 and the thermal imaging sensor 45, so that the thermal imaging sensor 45 can completely obtain the data of the electrical components 20 in the box-type substation 10. Under the action of the upper stabilizing component 44, the stability of the connecting component 41 during movement can be increased.

[0106] When the staff maintains the electrical components 20, they only need to operate the drive component 321 to move the connecting component 41 and the thermal imaging sensor 45 to the corner of the box-type substation 10. When maintaining the thermal imaging sensor 45, the staff only need to remove the connecting component 41, which increases the flexibility of equipment maintenance.

[0107] During temperature measurement, due to the large number of electrical devices inside the prefabricated substation, in order to reduce operating costs, it is not possible to install temperature measuring devices on all electrical structures. Temperature acquisition devices can only be installed on key electrical parts. Therefore, it is not possible to effectively and accurately reflect the operating temperature information inside the prefabricated substation. Therefore, this problem needs to be solved.

[0108] First, the staff can install the fixed outer shell 51 into a suitable position inside the box-type substation 10 via the carrier plate 512. The movable sliding part 52 can be used to adjust the position of the distribution motor 61. The wireless temperature measuring element 82 located in the first bearing groove 84 and the second bearing groove 841 in the support ring plate 71 is adjustable. The staff can rotate and remove the telescopic part 83 to attach multiple wireless temperature measuring elements 82 to key parts inside the electrical component 20, such as the high and low voltage leads of the main transformer, the connection points of important load equipment, cable terminals, voltage transformers, etc., to perform real-time contact temperature measurement. The wireless temperature measuring element 82 is movably connected to the damping universal joint of the telescopic part 83 through the outer protective part 821, which can flexibly adjust the angle of the wireless temperature measuring element 82. The telescopic part 83 has the ability to extend and can adjust the position of the wireless temperature measuring element 82. The wireless temperature measuring element 82 uses a wireless temperature sensor, which can prevent itself from affecting the equipment inside the electrical component 20 due to the difficulty in managing the cable. At the same time, it has the characteristics of low cost, low power consumption and high safety.

[0109] Multiple tension pipe fittings 73 can be installed around various auxiliary components within the electrical component 20. By adjusting the operation of the motor 61, the ring plate 62 and the main connecting pipe 63 are rotated until the main connecting pipe 63 rotates and is in a connected and fitted state with the auxiliary connecting pipe 72. The air pump 711 can transfer the heat in the air around the auxiliary electrical components of the electrical component 20 to the main connecting pipe 63 through the tension pipe fittings 73. The temperature sensor 64 can monitor and collect the temperature entering the main connecting pipe 63. Both the main connecting pipe 63 and the tension pipe fittings 73 are high-insulation pipes, which can reduce heat loss. The temperature data collected by the temperature sensor 64, after adding the heat loss, can finally determine the actual heat of the auxiliary components on the electrical component 20 around the tension pipe fittings 73. At the same time, the position of the fixed shell 51 can be flexibly adjusted so as not to affect the subsequent operation and maintenance of the electrical component 20.

[0110] Ultimately, without altering the basic structure of the original facilities of the electrical components 20 within the prefabricated substation 10, and by enabling efficient and flexible temperature acquisition and monitoring of the internal components of the electrical components 20, the operating costs are reduced, the labor intensity of maintenance personnel is lessened, and maintenance personnel are ultimately able to collect and monitor real-time temperature information of the equipment within the substation in a timely manner.
