Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment detection, and particularly relates to a data acquisition system for detecting power equipment in a substation. Background Art

[0002] A substation is a very important part of the power system. Its main function is to transform voltage, convert the high voltage sent by the transmission line into a low voltage suitable for users through a transformer, or increase the voltage of the electric energy generated by the power plant for transmission. In actual operation, the substation needs to have strict operation management and maintenance systems to ensure its safe, stable and reliable operation. For example, regular equipment inspections, preventive tests, fault detection and handling, etc.

[0003] With the continuous growth of the scale of substation equipment, the amount of on-site data collection in the substation specialty is increasing. Currently, it mostly relies on manual reading and transcription, and input on mobile platforms, resulting in a large workload for data copying, verification, and recording. Taking three operation scenarios of the electrical test specialty, namely the resistive current of arresters, SF6 gas testing, and insulating oil chromatographic testing, as examples, their testing workload, data collection volume, and data analysis volume are large. Taking the resistive current of arresters as an example, there are more than 100 power equipment arresters in a conventional substation. During the detection process, 12 data need to be collected for each phase, and nearly a thousand items of data need to be input each time, resulting in low work efficiency and the inability to call and analyze historical data. When detecting power equipment in an oil chromatographic workstation, an insulating oil chromatographic analyzer is used to detect the important equipment of the insulating oil in the transformer. In a conventional substation, there are also many transformers. Therefore, a large amount of data needs to be input each time during this detection. SF6 gas, that is, sulfur hexafluoride gas, is a protective gas widely used in various power equipment. In the on-site of the substation specialty, a leak detector is usually used to regularly detect the parts of power equipment prone to leakage. However, there are many power equipment using sulfur hexafluoride gas in the substation, such as GIS combined electrical appliances, voltage transformers, current transformers, and circuit breakers. Therefore, a large amount of data also needs to be input each time during this detection. Moreover, the arrester resistive current meters, SF6 gas testers, and oil chromatographic analyzers used for detection have the problem of low usability, increasing the intensity of the detection work for the entire substation.

[0004] Therefore, there is an urgent need for a new data acquisition mode in the substation to improve the detection work efficiency and reduce the intensity of the substation. Content of the Utility Model

[0032] Referring to Figure 4 , the present utility model provides a substation power equipment detection data acquisition system, and the detection data acquisition system includes: a power grid management platform 1, a detection device 2, and a workstation operation host 3.

[0033] Among them, the above-mentioned detection data acquisition system specifically includes the following in the implementation process:

[0034] I. Instrument software and hardware transformation

[0035] Upgrade and transform the chromatographic workstation software. The workstation software passes through the enterprise software "white list", and the workstation host accesses the internal network and is directly connected and interoperable with the power grid management platform. Revise the provincial operation documents, formulate the standard communication interface and data transmission communication protocol between the instrument and the power grid platform, binary code the transmitted information, the workstation directly obtains the work plan of the power grid management platform, associates the work plan, and "one-key uploads" the chromatographic data to the instruction book in the work plan, realizing the security of data interaction and communication with the internal network.

[0036] Upgrade the firmware of the arrester live tester and the SF6 gas leak detector and install a Bluetooth module. Revise the provincial operation documents, formulate the standard communication interface and data transmission communication protocol between the instrument and the power grid platform, binary code the transmitted information, and transmit it to the power grid management platform mobile APP through Bluetooth. The platform compares and analyzes the current value and the initial test data to realize the direct collection and transmission of instrument data.

[0037] II. Unify the system operation documents

[0038] Revise and release relevant provincial operation documents such as operation instruction books and record forms, and form operation items by unifying the standard forms, so that the form format can meet the work requirements of "recording by collection", ensuring the unity and standardization of the input data.

[0039] III. Unify the instrument communication protocol

[0040] Revise the technical specification for the procurement of live line lightning arrester testers, SF6 gas leak detectors, and oil chromatograph workstations. Newly add technical requirements such as basic requirements for communication interfaces, data and communication functions, mobile terminal methods, and general data coding. Unify the communication interfaces and data transmission protocols to ensure that the newly purchased instruments meet the requirements of the "recording by procurement" work.

[0041] IV. Database governance work

[0042] Sort out and export historical data from the power grid platform, establish a historical database in a unified data format, and import the "Maintenance and Test Regulations", standards, and various test data analysis models to meet the longitudinal comparison and intelligent analysis of equipment maintenance data, perform data anomaly analysis and reminders, and give play to data support for the full life cycle management of equipment.

[0043] Through the above implementation, the substation has carried out the transformation of instrument software and hardware in the way of "instrument communication + operation terminal + system platform", solidified the standard operation instruction manual, compiled the technical specification for instrument procurement, etc. It has realized the one-key reading of on-site test data through Bluetooth and scanning codes, and the system intelligent analysis. The three operation scenarios of resistive current of lightning arresters, SF6 gas testing, and insulating oil chromatographic testing in the electrical test specialty have bid farewell to manual data transcription, promoting the construction of the power grid instrument standardization system.

[0044] Among them, the following specific effects are achieved: reduce the amount of data entry by operators. After the standardization transformation, the instrument data can be reliably uploaded to the system without manual data transcription, realizing a reduction of 2.5 hours in the test work, reducing the data entry error rate to 0, and increasing the on-site operation efficiency by more than 5 times; the number of personnel arranged for each work in the team can be reduced, from 4 - 5 people required for each work to 2 - 3 people, saving labor costs, optimizing the team work plan, effectively reducing the burden and increasing the efficiency for front-line production workers through digital instruments, and achieving an economic benefit of 200,000 yuan per year.

[0045] In the substation power equipment detection data acquisition system provided by the present utility model, the detection equipment includes: live line lightning arrester testers, insulating oil chromatograph analyzers, and SF6 gas leak detectors. The following problems exist when the above equipment is used in this detection data acquisition system:

[0046] Figure 1 It is a schematic structural diagram of an existing live line lightning arrester tester. Refer to Figure 1 , the live line lightning arrester tester 100, that is, the lightning arrester resistive current meter, includes a housing 101 and a live line lightning arrester tester body 102 installed in the housing 101. Since the live line lightning arrester tester 100 needs to be connected to wires during use, the connecting wires and the live line lightning arrester tester 100 are usually installed separately and taken separately, so it is not convenient for operators to conduct tests.

[0047] To solve the problem of the convenience of carrying the live-line tester for lightning arresters in this detection data acquisition system, the present utility model improves the existing live-line tester for lightning arresters. Figure 5 FIG. is a schematic structural diagram of the live-line tester for lightning arresters in the detection data acquisition system provided by the present utility model. Refer to Figure 5 , a groove 1031 is provided on the inner side of the lid 103 of the housing 101 of the live-line tester for lightning arresters. An inner side plate 104 with an L-shaped cross-section is connected to the groove 1031. An inner baffle 105 is hinged on the lid 103. The inner side plate 104 and the groove of the lid 103 form a receiving cavity 106 for receiving connecting wires. A card slot is provided on the inner side plate 104, and a card block is formed on the inner baffle 105. The card block is snap-fitted in the card slot.

[0048] When the live-line tester for lightning arresters in the detection data acquisition system of the present utility model is in use, the connecting wire is placed in the receiving cavity 106, and the inner baffle 105 is clamped on the inner side plate 104 to prevent the connecting wire from sliding out of the receiving cavity 106 when taking and placing the live-line tester for lightning arresters.

[0049] Figure 2 FIG. is a schematic structural diagram of the existing insulating oil chromatographic analyzer. Refer to Figure 2 , the insulating oil chromatographic analyzer 200 includes a box body 201 and a sample injection mechanism, a sample gas separation mechanism, and a sample gas detection mechanism provided in the box body; heat dissipation openings 202 are provided on both sides of the box body 201. Heat dissipation holes 203 are provided on the heat dissipation openings 202, and an exhaust grille 204 is provided on the heat dissipation openings 202. The heat generated during the operation of the insulating oil chromatographic analyzer can be discharged to the exhaust grille 204 through the heat dissipation openings 202. Since the exhaust grille 204 is directly fixed to the side of the box body 201 of the insulating oil chromatographic analyzer and cannot be disassembled, there is usually a situation where dust cannot be cleaned thoroughly when cleaning the exhaust grille 204.

[0050] To solve the problem of inconvenient dust cleaning of the exhaust grille of the insulating oil chromatographic analyzer in this detection data acquisition system, the present utility model improves the existing insulating oil chromatographic analyzer. Figure 6 FIG. is a schematic structural diagram of the insulating oil chromatographic analyzer in the acquisition system provided by the present utility model. Refer to Figure 6 , a chute is opened on the heat dissipation opening 202 of the box body 201 of the insulating oil chromatographic analyzer. A ball 205 is connected to the exhaust grille 204. The ball 205 is mutually matched with the chute on the heat dissipation opening 202, so that the ball 205 can slide in the chute on the heat dissipation opening 202, thereby enabling the exhaust grille 204 to be easily installed in the heat dissipation opening 202. A groove 2021 is also provided on the heat dissipation opening 202. A spring 206 is connected in the groove 2021, and an L-shaped abutting plate 207 is connected to the spring 206.

[0051] Refer to Figure 6 , a cover plate 208 is hinged on the box body 201, and the cover plate 208 can cover the heat dissipation port 202 when the insulating oil chromatograph analyzer is not in use. A connecting rod 209 is hinged on the cover plate 208, and a mounting seat 210 is connected to the upper end of the cover plate 208 on the box body 201. A moving rod 211 is inserted through the mounting seat 210, and the connecting rod 209 can be connected to the moving rod 211.

[0052] When the insulating oil chromatograph analyzer in the detection data acquisition system of the present utility model is in use, the exhaust grille 204 is installed on the heat dissipation port 202 through the ball 205, so that the gas discharged from the heat dissipation holes 203 can reach the exhaust grille 204. The spring 206 is in an extended state, so that the L-shaped contact plate 207 extends out of the groove 2021, so that the groove 2021 can abut against the exhaust grille 204, playing a role in restricting the movement of the exhaust grille 204. The chute is arranged in the middle of the heat dissipation port 202, and the groove 2021 is arranged on the left and right sides of the chute. Among them, the cover plate 208 is opened, a hole is provided at the other end of the connecting rod 209 on the cover plate 208, and the connecting rod 209 can be inserted through the hole on the moving rod 211, and the moving rod 211 is inserted through the mounting seat 210, so that the opened cover plate 208 is fixed. When the insulating oil chromatograph analyzer is not in use, the moving rod 211 is taken out of the mounting seat 210, and the connecting rod 209 can also be taken out of the moving rod 211, so that the cover plate 208 naturally covers the heat dissipation port 202.

[0053] Figure 3 is a structural schematic diagram of an existing SF6 gas leak detector. Refer to Figure 3 , the SF6 gas leak detector 300 includes an outer box body 301 and a leak detector body 302 arranged in the outer box body 301. A moving wheel 303 is connected to the bottom of the outer box body 301. Since the SF6 gas leak detector 300 is supported by the moving wheel 303, when the SF6 gas leak detector 300 is placed on the ground, the SF6 gas leak detector 300 is likely to displace through the moving wheel 303. After the relative position of the SF6 gas leak detector 300 changes during the detection process, the cables and pipes on the SF6 gas leak detector 300 are likely to become loose and then fall off, affecting the detection.

[0054] In order to solve the problem that the SF6 gas leak detector in the present detection data acquisition system is unstable and easy to move during the detection operation, the present utility model improves the existing SF6 gas leak detector. Figure 7 is a structural schematic diagram of the SF6 gas leak detector in the acquisition system provided by the present utility model. Figure 8 is Figure 7 a view of the SF6 gas leak detector in the A direction in Figure 7 and Figure 8, a groove 3011 is provided at the bottom of the outer box body 301. A spring 304 is provided in the groove 3011. One end of the spring 304 is connected to a fixing plate 305. A connecting rod 306 is rotatably connected to the side surface of the fixing plate 305. A layer of anti-slip pad is provided on the surface of the fixing plate 305 facing the ground. A fixing column 307 is connected to the side wall of the outer box body 301. A lifting lug is provided on the connecting rod 306, and the connecting rod 306 can be connected to the fixing column 307 through the lifting lug. A jack is provided on the side surface of the fixing plate 305, and a plug post 308 is inserted into the jack. The plug post 308 and the connecting rod 306 are located on the same side surface of the fixing plate 305.

[0055] When the SF6 gas leak detector in the detection data acquisition system of the present utility model is in use, when the SF6 gas leak detector is placed at a certain position for detection operation, the connecting rod 306 is connected to the plug post 308, and the plug post 308 is then inserted into the jack of the fixing plate 305, so that the connecting rod 306 is horizontally arranged relative to the side surface of the fixing plate 305. Then, under the stretching action of the spring 304, the fixing plate 305 leaves the bottom of the outer box body 301 and descends to contact the ground, playing a role in stabilizing the SF6 gas leak detector and preventing the SF6 gas leak detector from shifting. Among them, the elastic force of the spring 304 can be selected according to the actual situation of the SF6 gas leak detector to meet the use requirements. When the SF6 gas leak detector does not need to be stabilized, the plug post 308 is taken out from the jack of the fixing plate 305, so as to take out the connecting rod 306 and connect the connecting rod 306 to the fixing column 307 on the side wall of the outer box body 301. During the process of connecting the connecting rod 306 to the fixing column 307, the spring 304 is compressed, and the fixing plate 305 rises to contact the bottom of the outer box body 301.

[0056] In summary, a substation power equipment detection data acquisition system provided by the present utility model adds a Bluetooth communication module to the existing detection equipment, and sets data interfaces for the power grid management platform and the workstation, realizing the convenience of data acquisition and output, and finally realizing "recording by acquisition". The entire detection data acquisition system has a high digital level. The same settings can be made for other substation professional testing instruments other than the above three instruments. In addition, since data can be transmitted between the workstation and the power grid management platform, the data in the power grid management platform can be effectively utilized by the workstation. The workstation can excavate, analyze and manage the value of test historical data. The system sets a unified data transmission communication protocol, making the standardization degree of substation power equipment operation data acquisition high. At the same time, the detection instrument is correspondingly improved, further reducing the detection operation intensity.

[0057] The foregoing description of specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made in accordance with the above teachings.
