[0002] A power system is an electrical energy production and consumption system composed of power plants, transmission and transformation lines, substations, and electricity consumers. Its function is to convert primary energy from nature into electrical energy through power generation devices, and then supply this electrical energy to various users through transmission, transformation, and distribution. To achieve this function, the power system also has corresponding information and control systems at various stages and levels to measure, regulate, control, protect, communicate, and dispatch the electrical energy production process, ensuring that users receive safe and high-quality electrical energy. Therefore, grid control equipment is needed to monitor the power system to ensure its stable and accurate operation.

[0003] After a period of operation, power grid control equipment needs to undergo data testing to reduce its errors. Currently, testing power grid control equipment requires manual use of a testing machine. Workers move the testing machine to one side of the power grid control equipment and then connect the terminals one by one, which is a slow testing process. Furthermore, for power grid control equipment requiring extended testing periods, workers need to wait alone, further impacting the testing speed. Summary of the Invention

[0006] In one possible implementation, the detection analyzer includes a housing, a detection analysis module, and a drive assembly. The free end of the linear actuator is connected to the housing. The housing has multiple mounting channels at the end away from the linear actuator, and the plug is slidably installed in the mounting channels. The detection analysis module is fixed inside the housing, and the plug is connected to the detection analysis module. The drive assembly is installed inside the housing and connected to the plug, for driving the plug to slide within the mounting channels.

[0008] In one possible implementation, the opening chute is a T-shaped groove, and the free end of the elevator is provided with a T-shaped plate adapted to the T-shaped groove; the linear actuator and the detection analyzer are both mounted on the T-shaped plate.

[0009] In one possible implementation, a plurality of the open slides are arranged around the center of the worktable; each side of the worktable is provided with at least two of the open slides.

[0010] In one possible implementation, the upper end of the worktable is further provided with a storage cavity, which is located between the open slides on both sides.

[0011] In one possible implementation, an electromagnet is fixed to the free end of the linear actuator, and the electromagnet is connected to the detection analyzer; by means of the opening or closing of the electromagnet, the linear actuator is fixedly connected to or separated from the detection analyzer.

[0012] In one possible implementation, the support device includes a support column and a connecting column fixed to the upper end of the support column, the support column being detachably connected to the worktable; the support column is used to support the ground, and the connecting column is used to connect to the detection analyzer.

[0013] In one possible implementation, a T-shaped block is provided on the outer side of the support column, and a vertical groove and a horizontal groove connected to the vertical groove are provided on the outer side of the worktable. The horizontal groove is adapted to and slidably connected to the T-shaped block. A pad for supporting the connecting column is also provided on the worktable.

[0014] In one possible implementation, the support device is a pneumatic cylinder or a hydraulic cylinder.

[0015] The beneficial effects of the power grid control equipment operation status detection and analysis system provided by this invention are as follows: Compared with the prior art, the power grid control equipment operation status detection and analysis system of this invention, during use, moves the workbench to the power grid control room via the walking wheels to test each power grid control device; the moving workbench positions the detection analyzer on one side of the power grid control device; the lifting device is activated to change the height of the linear drive and the detection analyzer, aligning the detection analyzer with the power grid control device; the linear drive is activated to push the detection analyzer outward in the open slide, and the plug is inserted into the interface on the power grid control device, thereby realizing the electrical connection between the power grid control device and the detection analyzer, and through detection... The analyzer tests the internal parameters of the power grid control equipment. When a longer test is required, the operator can remove the support device and lift the analyzer to allow it to work independently. The operator can then disconnect the free end of the linear actuator from the analyzer, allowing the workbench to move away from the current power grid control equipment and move to the next piece of equipment to be tested. This method allows for rapid movement within the power grid control room using the workbench, and the analyzer can detach from the workbench and operate independently. Therefore, multiple power grid control devices can be tested simultaneously without interference, improving testing speed and efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Please see Figures 1 to 6 The present invention will now describe the power grid control equipment operation status detection and analysis system provided. A power grid control equipment operation status detection and analysis system includes a workbench 100, a lifting device 200, a linear actuator 300, a detection and analysis device 400, and supporting components 500. The workbench 100 has an internal receiving cavity 110; the upper end of the workbench 100 has multiple open slide grooves 120, and the lower end has wheels 130; the open slide grooves 120 are connected to the receiving cavity 110; multiple lifting devices 200 are installed in the receiving cavity 110 and correspond one-to-one with the multiple open slide grooves 120; multiple linear actuators 300 are respectively installed in the receiving cavity 110. The upper end of the lifting device 200 is located within the open slide groove 120; multiple detection analyzers 400 are installed on the upper end of each lifting device 200, and the detection analyzers 400 are slidably installed within the open slide groove 120 and detachably connected to the free end of the linear drive 300; the detection analyzers 400 are provided with multiple plugs 410 for connecting to power grid control equipment; multiple support devices 500 are detachably connected to the workbench 100 and correspond one-to-one with multiple open slide grooves 120; the support devices 500 are used to support the detection analyzers 400.

[0030] The power grid control equipment operation status detection and analysis system provided by this invention, compared with the prior art, allows for the following operation: During use, the workbench 100 is moved to the power grid control room via the wheels 130 to test various power grid control devices. The moving workbench 100 positions the detector 400 to one side of the power grid control device. The lifting device 200 is activated to change the height of the linear actuator 300 and the detector 400, aligning the detector 400 with the power grid control device. The linear actuator 300 then pushes the detector 400 outward in the open slide 120, and the plug 410 is inserted into the interface on the power grid control device, thus establishing an electrical connection between the power grid control device and the detector 400. The detector 400 then monitors the power grid. The internal parameters of the control equipment are adjusted for testing. When a longer test is required, the operator can remove the support device 500 and lift the detector 400 for support, allowing the detector 400 to work independently. The operator can then disconnect the free end of the linear drive 300 from the detector 400, thereby moving the workbench 100 away from the current power grid control equipment to the next power grid control equipment to be tested. In this way, the workbench 100 can be moved quickly within the power grid control room, and the detector 400 can be detached from the workbench 100 to work independently. Therefore, multiple power grid control equipment can be tested simultaneously without mutual interference, improving testing speed and efficiency.

[0031] After the independently operating detection and analysis unit 400 completes the testing of the power grid control equipment, the workbench 100 moves to the location of the detection and analysis unit 400, corresponding to the open slide 120. By manipulating the movement of the workbench 100, the detection and analysis unit 400 slides into the open slide 120. Simultaneously, the free end of the linear actuator 300 is connected to the detection and analysis unit 400, and the linear actuator 300 is activated to reverse its movement, thereby pulling the detection and analysis unit 400 into the open slide 120. At the same time, the support device 500 is retracted, allowing the entire power grid control equipment operation status detection and analysis system to proceed to the next stage of testing.

[0032] This type of power grid control equipment operation status detection and analysis system has more diverse operation methods because the detector and analyzer 400 can work independently of the workbench 100.

[0033] Generally, a certain amount of testing time is required when testing various power grid control equipment. Therefore, the staff can control multiple test analyzers 400 on the workbench 100 to conduct independent test analyzer 400 tests on multiple power grid control equipment in the power grid control room. After a period of time, each test operation is completed, and the workbench 100 then retracts each test analyzer 400 one by one.

[0034] The detection analyzer 400 includes a current detection unit, a voltage detection unit, a temperature detection unit, a CPU, etc., and is used to complete the testing of power grid control equipment.

[0035] Please see Figures 1 to 3 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, the detection and analysis unit 400 includes a housing 420, a detection and analysis module 430, and a drive assembly 440. The free end of the linear driver 300 is connected to the housing 420. The end of the housing 420 away from the linear driver 300 is provided with a plurality of mounting channels 444, and the plug 410 is slidably installed in the mounting channels 444. The detection and analysis module 430 is fixed in the housing 420, and the plug 410 is connected to the detection and analysis module 430. The drive assembly 440 is installed in the housing 420 and connected to the plug 410, and is used to drive the plug 410 to slide in the mounting channels 444.

[0036] The detection and analysis module 430, drive assembly 440, plug 410, etc. are integrated into the housing 420, which is slidably connected to the open slide groove 120. Two mounting channels 444 are provided at the end of the housing 420 away from the linear driver 300. The plug 410 is slidably connected within the mounting channels 444.

[0037] After the housing 420 is slid outward by the linear actuator 300, when the end face of the housing 420 approaches the power grid control equipment, the linear actuator 300 is turned off, and the drive assembly 440 is activated to control the plug 410 to slide outward within the mounting channel 444. After the plug 410 passes through the mounting channel 444, it enters the interface on the power grid control equipment. The drive assembly 440 drives the plug 410 to move directly, making the movement of the plug 410 more stable and accurate.

[0038] A controller is installed on the workbench 100. The controller is connected to the traveling wheel 130, the linear driver 300, the drive assembly 440, etc., so that the above-mentioned multiple operations can be completed quickly and automatically.

[0039] Please see Figures 1 to 3 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, there are four mounting channels 444, arranged in pairs with vertical spacing, and four plugs 410; there are two drive components 440, which correspond to the two sets of mounting channels 444 respectively. The mounting channel 444 has a notch on the side near the drive component 440, and the outer surface of the plug 410 is provided with a rack. The drive component 440 includes a motor 441, a driving wheel 442 and two driven wheels 443. The motor 441 is connected to the driving wheel 442. The two driven wheels 443 are respectively installed on both sides of the driving wheel 442 and are meshed with the driving wheel 442. The two driven wheels 443 are respectively meshed with the two corresponding racks.

[0040] The four mounting channels 444 are arranged in a rectangular array. Two drive components 440 are set, located between the two sets of mounting channels 444 respectively. One drive component 440 is used to drive the plug 410 in the two mounting channels 444 to move.

[0041] The drive assembly 440 is a gear transmission mechanism, including a motor 441, a drive wheel 442, and two driven wheels 443. The motor 441 is connected to the drive wheel 442 to drive the drive wheel 442 to rotate, and driven wheels 443 are provided between the drive wheel 442 and each of the two mounting channels 444. The driven wheels 443 are engaged with the drive wheel 442 and also engage with the rack on the plug 410 through a notch. Therefore, by means of the connection between the drive wheel 442 and the two driven wheels 443, the two plugs 410 are driven to move simultaneously.

[0042] This reduces the number of drive components 440 required and improves the synchronization of movement of multiple plugs 410. Setting the motor 441 as a dual-head motor 441 allows the four plugs 410 to move synchronously.

[0043] Please see Figure 2 and Figure 4As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, the open chute 120 is a T-shaped chute, and the free end of the elevator 200 is provided with a T-shaped plate 210 adapted to the T-shaped chute; the linear drive 300 and the detection analyzer 400 are both installed on the T-shaped plate 210.

[0044] The detector 400 is slidably mounted in the transverse slot 160 of the open slide 120, while the linear drive is mounted in the vertical slot 150 of the open slide 120, making the installation of the detector 400 and the linear drive 300 relatively independent.

[0045] The receiving cavity 110 is connected to the open slide 120. A T-shaped plate 210 is installed on the free end of the lifting device 200. The T-shaped plate 210 slides in the T-slot. After the detection analyzer 400 and the linear actuator 300 are installed on the T-shaped plate 210, the lifting device 200 is started to control the vertical movement of the detection analyzer 400 and the linear actuator 300 to adjust the height of the plug 410.

[0046] Please see Figure 2 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, multiple open slides 120 are arranged around the center of the workbench 100; each side of the workbench 100 is provided with at least two open slides 120.

[0047] That is, an open slide 120 is provided on each side of the workbench 100, and the open slide 120s on each side are arranged side by side and will not affect each other; the detection analyzer 400 in each open slide 120 moves along the open slide 120.

[0048] This structure allows the workbench 100 to hold a larger number of detectors and analyzers 400, thereby increasing the testing performance of the power grid control equipment operation status detection and analysis system.

[0049] Multiple open slides 120 are arranged side by side on the same side of the workbench 100, so that the power grid control equipment operation status detection and analysis system can simultaneously detect and analyze multiple test points on a power grid control equipment and connect the analyzer 400 to the interface.

[0050] Please see Figures 1 to 4 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, the upper end of the workbench 100 is also provided with a storage cavity 140, which is located between the open slide grooves 120 on both sides.

[0051] A control panel can be installed inside the storage cavity 140, allowing staff to operate the entire power grid control equipment operation status monitoring and analysis system from within the storage cavity 140.

[0052] At the same time, the storage cavity 140 also reduces the weight of the entire worktable 100.

[0053] Please see Figure 1 and Figure 2 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, an electromagnet 310 is fixedly provided at the free end of the linear driver 300, and the electromagnet 310 is connected to the detection and analysis unit 400; by means of the opening or closing of the electromagnet 310, the linear driver 300 and the detection and analysis unit 400 are fixedly connected or separated.

[0054] The free end of the linear driver 300 is detachably connected to the detection analyzer 400 to facilitate the installation and removal of the linear driver 300 and the detection analyzer 400.

[0055] An electromagnet 310 is installed at the free end of the linear actuator 300, and the magnetic force generated by the electromagnet 310 is connected to the housing 420 of the detector analyzer 400. This method is relatively convenient to operate; the generation and disappearance of the magnetic force of the electromagnet 310 can be controlled simply by turning the control circuit on or off.

[0056] When the test analyzer 400 needs to be tested independently of the workbench 100, the circuit of the electromagnet 310 is disconnected so that there is no interaction force between the free end of the linear driver 300 and the test analyzer 400.

[0057] When it is necessary to retrieve the detector 400 that is working independently outside, the circuit of the electromagnet 310 is connected so that the free end of the linear driver 300 is connected to the detector 400 by magnetic attraction.

[0058] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, the support device 500 includes a support column 510 and a connecting column 520 fixed to the upper end of the support column 510. The support column 510 is detachably connected to the workbench 100. The support column 510 is used to support the ground, and the connecting column 520 is used to connect to the detection and analysis unit 400.

[0059] The cross-sectional dimensions of the support column 510 are larger than those of the connecting column 520. The support column 510 can be stably supported on the ground, while the upper end of the connecting column 520 rests on the lower end surface of the detection analyzer 400.

[0060] The support column 510 is detachably connected to the outer side of the worktable 100. When the detection analyzer 400 needs to work independently, the support column 510 can be removed from the worktable 100.

[0061] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 As a specific embodiment of the power grid control equipment operation status detection and analysis system provided by the present invention, a T-shaped block 530 is provided on the outer side of the support column 510, and a vertical groove 150 and a horizontal groove 160 connected to the vertical groove 150 are provided on the outer side of the workbench 100. The horizontal groove 160 is adapted to and slidably connected to the T-shaped block 530. A pad 170 for supporting the connecting column 520 is also provided on the workbench 100.

[0062] The transverse groove 160 is located in the T-shaped structure of the sliding fit of the T-block 530. When installing the support column 510 and the connecting column 520, the T-block 530 first enters the vertical groove 150 and slides in the vertical groove 150. When the T-block 530 is aligned with the transverse groove 160, the T-block 530 is controlled to slide along the transverse groove 160 and enter the transverse groove 160. With the help of the T-shaped structure to limit the T-block 530, the support column 510 can be connected to the worktable 100.

[0063] When it is necessary to remove the support device 500, the T-block 530 is controlled to slide in the horizontal groove 160 toward the vertical groove 150. After the T-block 530 enters the vertical groove 150, it moves along the vertical groove 150 to remove the T-block 530 and the support column 510 from the worktable 100.

[0064] Preferably, the support device 500 is a pneumatic cylinder or a hydraulic cylinder.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
