Description

Technical Field

[0001] This utility model relates to the field of power fault diagnosis, and in particular to an intelligent diagnostic instrument for power system faults. Background Technology

[0002] As one of the infrastructures of modern society, the power system plays a vital role in economic development and social stability. However, the power system is affected by various factors during operation, which can lead to faults. The intelligent fault diagnostic instrument for power systems is a device that integrates advanced computer hardware and software, sensors and data analysis technology. It is used to monitor, analyze and diagnose faults in the power system in real time, detect and handle faults in a timely manner, and thus ensure the safe and stable operation of the power grid.

[0003] In existing technologies, before using a power system fault intelligent diagnostic instrument, the connection structures of various test components need to be connected to the instrument. The test components test the power system, collect its parameters, and transmit them to the instrument for analysis to determine whether the power system has a fault. However, this method has certain limitations in practical use. Each time the instrument is used, the test components and power connection components need to be connected to it, and there are multiple test components and power connection components. This connection process is cumbersome and inefficient. Furthermore, during testing, the user needs to pull the test components to align them with the device under test. Excessive pulling or dragging can easily cause the connectors of the test components and power connection components to detach from the instrument's ports, affecting the testing results and making the instrument inconvenient to use. Therefore, this power system fault intelligent diagnostic instrument is proposed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Firstly, each time a power system fault intelligent diagnostic instrument is used, it requires connecting multiple test components and power connection components to the instrument, resulting in cumbersome and inefficient connection operations. Secondly, during testing, users need to pull the test components to align them with the device under test. Excessive pulling or dragging during this process can cause the connectors of the test components and power connection components to detach from the instrument's ports, affecting the testing results and making the instrument inconvenient to use. Therefore, this invention proposes a power system fault intelligent diagnostic instrument to solve these problems.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting the connection relationship between the housing, cable fault tester, connector, connector head, connecting plate, fixing block, and positioning port, the user can push the connecting plate into the rectangular groove, causing the connecting plate to move multiple sets of connector heads towards the corresponding connectors and insert them into the corresponding connectors. At this time, the fixing block is inserted and locked in the positioning port, thus fixing the position of the connector head. This helps to prevent the user from pulling or dragging the connector head away from the connector when using the equipment, which would affect the test results. Furthermore, by squeezing and pushing the fixing block inward through the positioning port, the fixing block is disengaged from the positioning port. At this time, the return spring pushes the pull rod and connecting plate outward, causing the connecting plate to move the connector head away from the connector, making it easy to remove the connector head from the connector, disconnect the equipment from the power supply, avoid unnecessary current flow, and protect the equipment from damage.

Then, the fixing ring is put on the outer wall of the connector head. By rotating the fixing ring, the fixing ring moves along the outer wall of the connector head towards the abutment plate, so that the abutment plate is pressed against the connecting plate, thereby fixing the connector head on the connecting plate. This makes it easy for the user to move the connector head by adjusting the position of the connecting plate. Furthermore, by rotating the fixing ring in the opposite direction, the fixing ring is disengaged from the connector head, making it easy to remove the connector head from the through hole for replacement.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example: This example provides an intelligent fault diagnostic instrument for power systems. See [link to example]. Figure 1-4 Specifically, including:

[0031] The system comprises a housing 1, a fault tester 2, and a connector 301. The fault tester 2 is housed within the housing 1, and a connector 203 is fixedly mounted on its outer wall. The connector 301 is inserted into the corresponding connector 203. When used outdoors, the housing 1 is opened to expose the fault tester 2. The external power supply connector 301 is then inserted into the corresponding connector 203 to provide power to the fault tester 2. The test equipment connector 301 is then inserted into the corresponding connector 203 to connect to the fault tester 2. After setting the fault parameters on the fault tester 2, clicking the "Sampling" button will automatically collect and display the waveform data. Clicking "Sampling" again will initiate continuous sampling. The operator adjusts the "Position" and "Amplitude" based on the displayed waveform until the collected data is suitable for analysis. When the waveform meets the analysis requirements, clicking the "Cancel Sampling" button stops sampling, thus enabling the diagnosis of the power system fault.

[0032] The fault tester 2 has a rectangular groove 202 on its outer wall, and a connecting component is provided on the inner wall of the rectangular groove 202. The connecting component includes:

[0033] The connecting plate 4 is movably inserted into the inner wall of the rectangular groove 202. The outer wall of the connecting plate 4 has a through hole 401, and multiple through holes 401 are provided. The corresponding connector 301 is movably inserted into the corresponding through hole 401, which is used to connect multiple sets of connectors 301 to the connecting plate 4 together, so as to facilitate simultaneous adjustment.

[0034] A snap-fit ​​unit is disposed on the connecting plate 4, which is used to confine the connecting plate 4 within the rectangular groove 202.

[0035] The snap-fit ​​unit includes a fixing block 404 and a fixing frame 405. A connecting groove 402 is provided on the outer wall of the connecting plate 4, and the fixing block 404 is movably snapped into the inner wall of the connecting groove 402. The fixing frame 405 is fixedly mounted on the outer wall of the fault tester 2, and a positioning port 406 is provided on the outer wall of the fixing frame 405. The fixing block 404 is mated and snapped into the positioning port 406. In use, the user pushes the connecting plate 4 into the rectangular groove 202, causing the connecting plate 4 to move multiple sets of connectors 301 toward the corresponding connectors 203, so that the corresponding connectors 301 are inserted into the corresponding... The connector 203 connects various devices, and the moving connecting plate 4 drives the fixed block 404 to move. When the corresponding connector 301 is inserted into the corresponding connector 203, the fixed block 404 aligns with the positioning port 406. The fixed block 404 moves outward, so that it is inserted into and locked in the positioning port 406, thus restricting the connecting plate 4 within the rectangular groove 202. This fixes the position of the connector 301 and prevents the user from pulling or dragging the connector 301, causing it to detach from the connector 203 and affecting its use.

[0036] A compression spring 403 is fixedly installed on the inner wall of the connecting groove 402, and the other end of the compression spring 403 is fixedly installed on the outer wall of the fixing block 404. The compression spring 403 pushes the fixing block 404 outward, so that the fixing block 404 is inserted into and locked in the positioning port 406, further improving stability.

[0037] A stop plate 302 is fixedly provided on the outer wall of the connector 301, and the radial width of the stop plate 302 is greater than the radial width of the through hole 401. A fixing ring 303 is threadedly connected to the outer wall of the connector 301, and the radial width of the fixing ring 303 is greater than the radial width of the through hole 401. In use, the user inserts the corresponding connector 301 into the corresponding through hole 401, and then puts the fixing ring 303 on the outer wall of the connector 301. By rotating the fixing ring 303, the fixing ring 303 moves along the outer wall of the connector 301 toward the stop plate 302, so that the stop plate 302 abuts against the connecting plate 4, thereby fixing the connector 301 to the connecting plate 4.

[0038] A connecting wire 3 is fixedly provided on the outer wall of the connector 301, and the connector 301 is electrically connected to the external device through the connecting wire 3.

[0039] A connecting block 5 is fixedly installed in the inner cavity of the rectangular groove 202. A movable groove 501 is opened on the outer wall of the connecting block 5, and a pull rod 503 is movably engaged in the inner wall of the movable groove 501. The other end of the pull rod 503 is fixedly installed on the outer wall of the connecting plate 4, which restricts the movement path and movement range of the connecting plate 4, so that the connector head 301 is aligned with the connector 203.

[0040] A return spring 502 is fixedly installed on the inner wall of the moving slot 501, and the other end of the return spring 502 is fixedly connected to the outer wall of the pull rod 503. When the fixed block 404 is retracted into the connecting slot 402 and disengaged from the positioning port 406, the pull rod 503 is pushed outward by the pushing force of the return spring 502. The outwardly moving pull rod 503 pushes the connecting plate 4 outward, so that the connecting plate 4 drives the connector 301 to disengage from the connector 203. This makes it easy to remove the connector 301 from the connector 203, disconnect the equipment from the power supply, avoid unnecessary current flow, and protect the equipment from damage.

[0041] The fault tester 2 has a display screen 201 fixedly installed on its outer wall.

[0042] Specifically, the working principle and operation method of this utility model are as follows:

[0043] In use, after opening the housing 1, the user pushes the connecting plate 4 into the rectangular groove 202, causing the connecting plate 4 to move multiple sets of connectors 301 towards their corresponding connectors 203, thus connecting the various devices. The moving connecting plate 4 also moves the fixing block 404. When the corresponding connector 301 is inserted into the corresponding connector 203, the fixing block 404 aligns with the positioning port 406. The force of the compression spring 403 pushes the fixing block 404 outward, causing it to insert and lock into the positioning port 406. This confines the connecting plate 4 within the rectangular groove 202, fixing the position of the connectors 301 and preventing the user from pulling or dragging them during use. Pulling causes connector 301 to detach from connector 203, affecting test results. By squeezing and pushing the fixing block 404 inward through the positioning port 406, the fixing block 404 is retracted into the connecting groove 402 and disengaged from the positioning port 406. At this time, the pushing force of the return spring 502 pushes the pull rod 503 outward, causing the outwardly moving pull rod 503 to push the connecting plate 4 outward, so that the connecting plate 4 drives connector 301 to detach from connector 203, making it easy to remove connector 301 from connector 203, disconnecting the equipment from the power supply, avoiding unnecessary current flow, and protecting the equipment from damage. Furthermore, by adjusting the position of the connecting plate 4, multiple sets of connectors 301 can be moved simultaneously, allowing users to control multiple sets of connectors 301 at the same time, reducing operation steps and improving user testing efficiency.

[0044] In use, the user inserts the corresponding connector 301 into the corresponding through-hole 401 according to the position of the corresponding connector 301 and the corresponding connector 203, and then puts the retaining ring 303 on the outer wall of the connector 301. By rotating the retaining ring 303, the retaining ring 303 moves along the outer wall of the connector 301 towards the abutment plate 302, so that the abutment plate 302 presses against the connecting plate 4, thereby fixing the connector 301 on the connecting plate 4. By rotating the retaining ring 303 in the opposite direction, the retaining ring 303 is disengaged from the connector 301, making it easy to remove the connector 301 from the through-hole 401 for replacement.
