Description

Technical Field

[0001] This utility model relates to the field of power supply performance testing technology, and in particular to a power supply parallel performance testing device. Background Technology

[0002] As the nervous system of a generator set, the DCS system typically uses dual parallel DC power modules for power supply to improve its reliability. However, some existing control power supplies lack online current sharing functionality. In actual operation, the load distribution of the power modules is random. During normal generator set operation, the power modules are in a state of continuous operation for a long period of time. With the increase in service life, varying degrees of aging and performance drift will occur. Over time, this will lead to a decrease in load capacity, uneven load distribution, and even power module failure leading to power outages and unscheduled generator shutdowns, seriously affecting the safety and economy of the generator set and the stable operation of the power grid.

[0003] Currently, existing parallel performance tests for power supplies can only be completed in the laboratory. The testing equipment is specially customized, bulky, complex to operate, and has a long testing cycle. The power modules of the DCS system are only tested for parallel performance before leaving the factory. The power modules after leaving the factory have never undergone this test. After the DCS system is powered on, the power modules of the control cabinet are already assembled and there is no power outage condition, so they cannot be removed and sent for testing.

[0004] Therefore, there is an urgent need for a portable device for testing the parallel power supply performance of a power plant's DCS system while it is in service. Utility Model Content

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following reference Figures 1-5This invention describes a power supply parallel performance testing device according to an embodiment of the present invention.

[0027] like Figures 1-5 As shown, the power supply parallel performance testing device according to an embodiment of the present invention includes a housing 1, a partition 3, a power supply component, a testing device 6, an electronic load 7, and a current sensor 8.

[0028] Specifically, the outer casing 1 has an open storage groove at the top, and a partition 3 is disposed in the storage groove to divide the storage groove into a first chamber 4 and a second chamber 5. The outer casing 1 also has a cavity 22. The storage groove has cavities 22 on both sides in the length direction of the partition 3. A wire-passing hole is formed on the inner wall of the second chamber 5 to connect the second chamber 5 and the cavity 22. A through hole 21 is formed on the outer wall of the outer casing 1 away from the second chamber 5 in the thickness direction of the partition 3 to communicate with the cavity 22. The test device 6 and the electronic load 7 are disposed in the first chamber 4, the power supply is disposed in the second chamber 5, and the current sensor 8 is disposed in the cavity 22. The test device 6 and the current sensor 8 are both suitable for electrical connection with the power supply.

[0029] When testing is required, the operator can move the power supply parallel performance testing device to the measurement location by moving the outer casing 1. During the test, the current sensor 8 is connected to the power module of the DCS system through the through hole 21. The power supply unit is electrically connected to the current sensor 8 through the wire hole to supply power to the current sensor 8. The power supply unit is also electrically connected to the test equipment 6 to supply power to the test equipment 6. The electronic load 7 is connected to the power module of the DCS system to adjust the load of the power module of the DCS system.

[0030] The test device 6 has a data acquisition card, which is connected to the current sensor 8 to acquire the corresponding current value. At the same time, the test device 6 is electrically connected to the electronic load 7 to adjust the load value of the electronic load 7. There are multiple power sensors, which are connected to the branch circuit and the main circuit respectively to acquire the current value of each branch circuit and the current value of the main circuit.

[0031] Test device 6 records: the total output current of the DC circuit, the output current of each power supply, and the current load value of each power supply, and calculates the corresponding output voltage value based on the current and load values. This enables the parallel performance testing of the power supply modules in the DCS system.

[0032] Preferably, the partition 3 is installed perpendicular to the bottom of the storage slot. The test device 66 is a PC, specifically a flip-top electronic product, which includes a display screen for displaying test data and a control keyboard. The test device 66 contains test software, and its rear end has several D-type interfaces, several USB interfaces, and several Ethernet interfaces for circuit connections before circuit testing. The power supply is preferably a low-ripple power supply for powering the data acquisition card and the current sensor 8.

[0033] According to the power supply parallel performance testing device of this utility model embodiment, by integrating the components for realizing the power supply parallel performance test into the housing 1, the integration of the power supply parallel performance testing device can be improved. It is more convenient to carry during the test, and the operation is simpler for the operator. It can reduce the difficulty of power supply parallel performance testing, and the housing 1 can protect the components for realizing the power supply parallel performance test.

[0034] In some embodiments, such as Figure 1 As shown, the power supply parallel performance testing device also includes: a base plate 17 and a pull-out slide rail 18. There are two pull-out slide rails 18, which are respectively fixed on the two side walls of the first chamber 4 along the length of the partition 3. The pull-out slide rails 18 can extend and retract vertically. The two ends of the base plate 17 are rotatably connected to the inner sides of the two pull-out slide rails 18. The testing equipment 6 and the electronic load 7 are supported on the base plate 17.

[0035] After moving the power supply parallel performance testing device to the test location, the base plate 17 is first pulled out of the first chamber 4. The sliding rail 18 is pulled upward by the base plate 17. It should be noted that the locking force of the sliding rail 18 itself is greater than the weight of the base plate 17 and the components on the base plate 17. In this way, the sliding rail 18 can support the base plate 17 at a set height. Then, the base plate 17 is rotated according to the connection requirements of the test so that the test equipment 6 and the electronic load 7 are at a suitable angle. This can further reduce the difficulty of the test.

[0036] After the test is completed, the base plate 17 drives the pull-out slide rail 18 to retract, which completes the storage of the parts. The operation process is quite convenient.

[0037] In some embodiments, such as Figures 3-5 As shown, the power supply parallel performance testing device also includes: a support plate 9, which is rotatably mounted on the base plate 17, and the testing equipment 6 and the electronic load 7 are supported on the support plate 9.

[0038] Therefore, during the testing process, the angles of the testing equipment 6 and the electronic load 7 can be adjusted in multiple dimensions by adjusting the height of the base plate 17, the angle of the base plate 17 relative to the pull-out slide rail 18, and the angle of the support plate 9 on the support surface of the base plate 17. This makes it easier for the testing equipment 6 and the electronic load 7 to be connected to other components, further reducing the difficulty of operation.

[0039] In some embodiments, such as Figure 4 and Figure 5 As shown, the support plate 9 is provided with a positioning block 19, and the positioning block 19 is provided with an annular plate 32 arranged around the positioning block 19. The bottom plate 17 is provided with a first arc-shaped groove 20, and the side wall of the first arc-shaped groove 20 is provided with a second arc-shaped groove 33 that is adapted to the annular plate 32. The positioning block 19 is slidably disposed in the first arc-shaped groove 20, and the annular plate 32 is fitted in the second arc-shaped groove 33.

[0040] In this way, by sliding the positioning block 19 within the first arc-shaped groove 20, the support plate 9 can rotate on the base plate 17. The first arc-shaped groove 20, in conjunction with the positioning block 19, and the second arc-shaped groove 33, in conjunction with the annular plate 32, can limit and guide the rotation of the support plate 9. The second arc-shaped groove 33, in conjunction with the annular plate 32, can prevent the positioning block 19 from dislodging from the first arc-shaped groove 20, thereby improving the reliability of the connection between the base plate 17 and the support plate 9. Furthermore, the second arc-shaped groove 33, in conjunction with the annular plate 32, can limit the displacement of the support plate 9 in the thickness direction of the base plate 17, so that the support plate 9 can be supported on the base plate 17.

[0041] Preferably, the positioning block 19 is cylindrical, and the included angle of the first arc groove 20 is the included angle that supports the support plate 9 to rotate 90 degrees on the support surface of the base plate 17.

[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the power supply parallel performance testing device also includes: a first movable plate 10 and a second movable plate 11. The support plate 9 is provided with two telescopic rods 12 that can extend and retract along a first direction. The two telescopic rods 12 extend in opposite directions. The first movable plate 10 and the second movable plate 11 are respectively connected to the two telescopic rods 12. The testing device 6 is located on the first movable plate 10, and the electronic load 7 is located on the second movable plate 11.

[0043] Therefore, during the test, the first moving plate 10 and the second moving plate 11 can be moved by the two telescopic rods 12 respectively, so that the positions of the test equipment 6 and the electronic load 7 on the support plate 9 can be adjusted respectively, thereby further reducing the connection difficulty during the test.

[0044] Preferably, the support plate 9 and the base plate 17 are arranged at intervals, and the telescopic rod 12 is located on the side of the support plate 9 facing the base plate 17. The first moving plate 10 and the second moving plate 11 both include an L-shaped first plate segment and a second plate segment. The first plate segment is connected to the telescopic rod 12, and the second plate segment is located on the side of the support plate 9 away from the base plate 17. When the telescopic rod 12 is opened to the maximum extension position, the first moving plate 10 and the second moving plate 11 still partially overlap.

[0045] In some embodiments, a plurality of support columns are added to the side of the second movable plate 11 facing the base plate 17. The top of the support column is hemispherical and ball bearings are embedded and rolled on its top to support the second movable plate 11, thereby improving the stability of the second movable plate 11 during movement.

[0046] In some embodiments, a flexible material, such as rubber, is provided on the inner wall of the first chamber 4. When the base plate 17 drives each component to be stored in the storage groove, the flexible material can protect each component, thereby reducing the probability of damage to each component.

[0047] In some embodiments, such as Figure 1 and Figure 4 As shown, the power supply parallel performance testing device also includes: a third moving plate 13, a slider 14 fixedly connected to the bottom of the third moving plate 13, a groove 15 adapted to the slider 14 on the support plate 9, the groove 15 extending along the second direction, the second direction being perpendicular to the first direction, and two push rods 16 rotatably connected to the slider 14, which are respectively rotatably connected to the first moving plate 10 and the second moving plate 11.

[0048] Therefore, during the test, the slider 14 and the groove 15 cooperate to restrict the movement of the third moving plate 13 in the second direction. By pushing the third moving plate 13 in the second direction, the third moving plate 13 drives one end of the push rod 16 to move in the second direction through the slider 14. In this way, the push rod 16 can drive the first moving plate 10 and the second moving plate 11 to move in the first direction. Thus, by changing the movement direction of the third moving plate 13 in the second direction, the first moving plate 10 and the second moving plate 11 can be unfolded and retracted, thereby further reducing the operational difficulty during the test.

[0049] Preferably, the third movable plate 13 is provided with a storage box, which facilitates the storage of tools at the test site.

[0050] In some embodiments, such as Figure 1 and Figure 2As shown, a placement slot 24 is provided on both sides of the storage slot along the length of the partition 3 inside the outer shell 1. The upper end of the placement slot 24 is open. The placement slot 24 is located on the upper side of the cavity 22. The placement slot 24 extends along the thickness direction of the partition 3. In the direction from the second chamber 5 to the first chamber 4, the placement slot 24 extends downward at an angle. A connecting block 25 is slidably connected to each placement slot 24. A top cover 2 is rotatably connected to the edge of the placement slot 24 away from the first chamber 4 along the thickness direction of the partition 3. Fixing blocks are fixed to both sides of the top cover 2. A first pull rod 34 is fixed to each of the two connecting blocks 25. A second pull rod 35 is rotatably connected to each of the two fixing blocks. The first pull rod 34 and the second pull rod 35 are hinged together.

[0051] When the top cover 2 closes the opening of the storage slot, the first pull rod 34 and the second pull rod 35 are both stored in the placement slot 24. When the top cover 2 opens the opening of the storage slot, the first pull rod 34 and the second pull rod 35 extend out from the placement slot 24.

[0052] During the process of opening and closing the opening of the placement slot 24 of the top cover 2, the first pull rod 34 and the second pull rod 35 can guide and restrict the rotation path of the top cover 2, thereby improving the positional accuracy of the opening and closing process of the top cover 2.

[0053] In some embodiments, such as Figure 2 As shown, a movable groove 31 extending along the thickness direction of the partition 3 is formed on the inner wall of the cavity 22. A movable block 23 is also provided in the cavity 22. The movable block 23 is movably disposed in the movable groove 31 along the thickness direction of the partition 3. The current sensor 8 is disposed on the side of the movable block 23 facing the through hole 21. The power supply parallel performance testing device is configured such that when the top cover 2 opens the storage groove, the top cover 2 drives the movable block 23 to move toward the through hole 21 so that the connection port of the current sensor 8 extends out of the through hole 21. When the top cover 2 closes the storage groove, the top cover 2 drives the movable block 23 away from the through hole 21 so that the connection port of the current sensor 8 retracts from the through hole 21.

[0054] By linking the top cover 2 with the current sensor 8, when the power supply is tested by opening the top cover 2, the connection port of the current sensor 8 extends out from the through hole 21, which facilitates the connection between the current sensor 8 and the power supply, thereby further reducing the difficulty of testing. When the top cover 2 is closed, the connection port of the current sensor 8 retracts from the through hole 21, and the outer shell 1 can protect the connection port of the current sensor 8 to avoid damage to the connection port of the current sensor 8.

[0055] Preferably, the moving block 23 is inverted T-shaped, which can improve the stability of the moving block 23 during the movement process.

[0056] In some embodiments, such as Figure 2As shown, a first groove 28 is also formed inside the outer shell 1. The first groove 28 includes a first section, a second section and a third section. The first section and the third section extend along the thickness direction of the partition 3 and are arranged vertically at intervals. The second section extends vertically and is located on the side of the cavity 22 away from the through hole 21. The second section connects between the first section and the third section. The first section connects between the placement groove 24 and the second section. The third section connects between the second section and the cavity 22. A first connecting rope 29 is provided in the first groove 28. The first connecting rope 29 connects between the connecting block 25 and the moving block 23.

[0057] During the closing process of the top cover 2, the top cover 2 pushes the connecting block 25 toward the through hole 21 through the first pull rod 34 and the second pull rod 35. At the same time, under the restriction of the force transmission direction of the first connecting rope 29 by the first groove 28, the connecting block 25 pulls the moving block 23 away from the through hole 21 through the first connecting rope 29, so that the connection port of the current sensor 8 gradually retracts from the through hole 21.

[0058] Therefore, when the top cover 2 closes the storage slot, the top cover 2 drives the moving block 23 to move away from the through hole 21, so that the connection port of the current sensor 8 can be retracted from the through hole 21. Moreover, the component structure is relatively simple, and the design and production difficulty are low.

[0059] In some embodiments, such as Figure 2 As shown, a second groove is also formed inside the outer shell 1. The second groove extends vertically and is formed between the cavity 22 and the outer wall of the outer shell 1 on one side where the through hole 21 is provided. The through hole 21 passes through the inner wall of the second groove and communicates with the cavity 22. The upper end of the second groove is connected to the placement groove 24, and the lower end of the second groove is connected to the cavity 22. A flexible push plate 26 is provided in the placement groove 24 and the second groove. A connecting groove 27 corresponding to the through hole 21 is opened on the flexible push plate 26. The upper end of the flexible push plate 26 is connected to the connecting block 25, and the lower end of the flexible push plate 26 is connected to the moving block 23 through the second connecting rope 30.

[0060] In other words, the upper end of the flexible push plate 26 extends from the second groove into the placement groove 24 and is connected to the connecting block 25, and the second connecting rope 30 extends from the lower end of the second groove into the cavity 22 and is connected to the moving block 23.

[0061] The vertical dimension of the connecting groove 27 is larger than that of the through hole 21 in the vertical direction. As the connection port of the current sensor 8 extends, the connecting groove 27 avoids the connection port of the current sensor 8.

[0062] During the opening of the top cover 2, the top cover 2 pulls the connecting block 25 away from the through hole 21 by the first pull rod 34 and the second pull rod 35. Under the force transmission direction restriction of the second groove on the flexible push plate 26 and the second connecting rope 30, the connecting block 25 gradually drives the moving block 23 to move towards the through hole 21 by the flexible push plate 26 and the second connecting rope 30, so that the connection port of the current sensor 8 gradually protrudes from the through hole 21.

[0063] Therefore, when the top cover 2 closes the storage slot, the top cover 2 drives the moving block 23 to move away from the through hole 21, so that the connection port of the current sensor 8 can be retracted from the through hole 21. Moreover, the component structure is relatively simple, and the design and production difficulty are low.

[0064] When the top cover 2 closes the opening of the storage slot, the connecting block 25 pulls the moving block 23 away from the through hole 21 through the first connecting rope 29, and the connecting groove 27 on the flexible push plate 26 is offset from the through hole 21, so the flexible push plate 26 can close the through hole 21.
