Description

A simulation fixture and testing device for installation Technical Field

[0001] This application relates to the field of equipment testing technology, and more specifically, to an installation simulation fixture and testing device. Background Technology

[0002] In power systems, performance testing of numerous devices is necessary to ensure the safe and stable operation of the entire system. Taking fuses as an example, as a crucial protective component, their performance directly impacts the safe and stable operation of the entire power system. However, most current testing devices can only provide test results under a single installation configuration, failing to reflect the true performance of the device under test in actual operating conditions.

[0003] In summary, how to enable the testing device to better reflect the actual performance of the device under test in real working conditions has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, this application provides an installation simulation fixture and testing device, so that the testing device can better reflect the real performance of the device under test in actual working conditions.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An installation simulation fixture, comprising:

[0007] A frame is provided with at least two mounting brackets, and two adjacent mounting brackets are arranged opposite to each other on the frame along a first direction. Each mounting bracket is provided with a fixing part, and the fixing parts of two adjacent mounting brackets are respectively used to fix the two ends of the device under test.

[0008] The fixing part is adjustable in a second direction relative to the frame, where the second direction is the height direction of the frame and the first direction is perpendicular to the second direction.

[0009] In some embodiments of this application, the rack is further provided with a mounting frame, and the mounting bracket is disposed on the mounting frame and is adjustable relative to the mounting frame in the second direction.

[0010] In some embodiments of this application, the mounting bracket is fixed to the top surface of the mounting frame by fasteners, and the mounting bracket is equipped with an adjusting shim. The adjusting shim is used to adjust the mounting height of the mounting bracket on the mounting frame, so as to make the setting position of the mounting bracket relative to the mounting frame in the second direction adjustable.

[0011] In some embodiments of this application, the adjustment of the mounting bracket relative to the mounting frame in the second direction is achieved by increasing or decreasing the number of adjusting shims;

[0012] Alternatively, the mounting bracket can be adjusted relative to the mounting frame in the second direction by replacing the adjusting shims with different thicknesses.

[0013] In some embodiments of this application, the mounting frame is provided with a lifting mechanism, and the mounting bracket is disposed at the lifting end of the lifting mechanism.

[0014] In some embodiments of this application, the rack is provided with at least two connecting brackets, two adjacent connecting brackets are arranged opposite each other in a third direction, the two opposite ends of the mounting frame in the third direction are respectively connected to the two adjacent connecting brackets, and the connection position of the mounting frame on the connecting bracket is adjustable in the second direction; wherein, the first direction, the second direction and the third direction are perpendicular to each other.

[0015] In some embodiments of this application, the connecting bracket is provided with connecting holes spaced apart along the second direction, and the connecting holes are used for fixed connection with the corresponding end of the mounting frame;

[0016] Alternatively, the connecting bracket may be provided with a first waist-shaped hole arranged along the second direction, the first waist-shaped hole being used for fixed connection with the corresponding end of the mounting frame.

[0017] In some embodiments of this application, the mounting bracket includes a first clamping plate, a second clamping plate, and a fixing lead wire. The first clamping plate and the second clamping plate are arranged opposite to each other in the second direction. The first clamping plate is disposed on the mounting frame. The fixing lead wire has a first lead wire segment and a second lead wire segment connected to the first lead wire segment. The first lead wire segment extends along the first direction, and the second lead wire segment extends along the second direction. The fixing part is disposed at the end of the first lead wire segment away from the second lead wire segment, and the first lead wire segment is clamped between the first clamping plate and the second clamping plate.

[0018] In some embodiments of this application, the fixing part is a first fixing hole provided on the first lead segment, and the end of the device under test is provided with a second fixing hole that matches the first fixing hole. The first fixing hole and the second fixing hole are fixedly connected by fasteners.

[0019] In some embodiments of this application, an insulator is provided on the end face of the mounting frame opposite to the second lead segment, and a third fixing hole is provided on the second lead segment for fixed connection with the insulator, and the third fixing hole is configured as a second oblong hole extending along a second direction.

[0020] In some embodiments of this application, the frame is provided with calibration scale lines arranged along the second direction; and / or, the mounting frame is provided with a level indicator.

[0021] In some embodiments of this application, the mounting position of the fixing part relative to the frame in the first direction is adjustable.

[0022] To enable the fuse testing device to better reflect the actual performance of fuses under real-world operating conditions, the fuse testing device provided in this application includes a frame with at least two mounting brackets. Two adjacent mounting brackets are arranged opposite each other on the frame along a first direction. Each mounting bracket has a fixing part, which is used to fix the two ends of the device under test (DUT). The fixing part is adjustable relative to the frame in a second direction, where the second direction is the height direction of the frame, and the first direction is perpendicular to the second direction. During actual testing, by fixing the two ends of the DUT to the corresponding fixing parts on the two mounting brackets, and since the fixing part is adjustable relative to the frame in the second direction (i.e., its position along the height direction of the frame), the height difference between the two ends of the DUT can be adjusted. This simulates the actual installation position of the DUT under real-world operating conditions, thus better simulating the actual performance of the DUT during testing, improving test accuracy, and allowing for different testing requirements of the DUT by adjusting to different height differences.

[0023] On the other hand, this application also provides a testing device, including a mounting simulation fixture and a housing. The mounting simulation fixture is the mounting simulation fixture described in any of the above-mentioned solutions. The housing surrounds the frame of the mounting simulation fixture, and a test interface is provided on the housing, which is electrically connected to the device under test. Since the aforementioned mounting simulation fixture has the above-mentioned technical effects, the testing device with this mounting simulation fixture should also have corresponding technical effects, which will not be elaborated further here.

[0024] In some embodiments of this application, the housing includes a circumferential enclosure surrounding the frame and a top enclosure disposed on the top of the frame;

[0025] The frame is provided with a set of wheels at its bottom; and / or the top panel is provided with an observation window; and / or at least one side of the circumferential panel is provided with an openable and closable door.

[0060] The core of this application is to provide an installation simulation fixture and testing device, so that the testing device can better reflect the real performance of the device under test in actual working conditions.

[0061] 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 some embodiments of this application, and not all embodiments. 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.

[0062] In power systems, performance testing of numerous devices is necessary to ensure the safe and stable operation of the entire system. Taking fuses as an example, as a crucial protective component, their performance directly impacts the safe and stable operation of the entire power system. However, most current testing devices can only provide test results under a single installation configuration, failing to reflect the true performance of the device under test in actual operating conditions.

[0063] Taking fuses as an example, the applicant found through research that the uneven height of the two ends of the fuse during installation, that is, the difference in the installation position of the two ends of the fuse may lead to an increase in the internal resistance of the fuse, thereby affecting its normal operation.

[0064] Based on this, embodiments of this application provide an installation simulation fixture so that the testing device can better reflect the actual performance of the device under test in actual working conditions.

[0065] Specifically, as shown in Figure 2, the testing device includes a frame 1, which mainly serves as the main frame of the testing device. Specifically, it can be, but is not limited to, a square frame assembled from multiple frame beams. The connection between the frames can be a fastener connection or a welding connection, without specific limitations here.

[0066] The frame 1 is provided with at least two mounting brackets 11, that is, two or more mounting brackets 11 can be provided. The two adjacent mounting brackets 11 are arranged opposite to each other on the frame 1 along the first direction. Each mounting bracket 11 is provided with its own corresponding fixing part 12. The fixing parts 12 of the two adjacent mounting brackets are used to fix the two ends of the device under test 2. The initial fixing of the device under test 2 can be completed by fixing the two ends of the device under test 2 to the fixing parts 12 of the two adjacent mounting brackets 11.

[0067] Meanwhile, the fixing part 12 is adjustable in position relative to the frame 1 in the second direction. Specifically, this adjustment can be achieved by displacing the mounting bracket 11 relative to the frame 1 in the second direction; alternatively, the fixing part 12 itself can be adjusted in position on the mounting bracket 11 in the second direction; or, the mounting bracket 11 can be adjusted in position relative to the frame 1 in the second direction, and the fixing part 12 itself can also be designed to be adjustable in position on the mounting bracket 11 in the second direction. Any method that allows for adjustment of the fixing part 12's position relative to the frame 1 in the second direction is acceptable and is not specifically limited here. The specific structural form of this adjustable position will be described in detail in later embodiments.

[0068] In addition, the second direction described in this application is the height direction of the frame 1, and the first direction is the direction perpendicular to the second direction. For example, when the frame 1 is a cuboid frame, the first direction can be the length direction of the frame 1 or the width direction of the frame 1.

[0069] In actual testing, by fixing the two ends of the device under test 2 to the corresponding fixing parts 12 on two adjacent mounting brackets 11, the height difference between the two ends of the device under test 2 can be adjusted because the fixing part 12 is adjustable relative to the frame 1 in the second direction, that is, its position along the height direction of the frame 1. This allows the actual installation position of the device under test 2 under actual working conditions to be simulated. In this way, the actual performance of the device under test 2 can be better simulated during testing, improving the accuracy of the test. At the same time, different testing requirements of the device under test 2 can be met by adjusting to different height differences.

[0070] For example, the device under test 2 can be a fuse. By adjusting the two ends of the fuse to different height differences, and then testing the internal resistance of the fuse, the influence of the height difference between the two ends of the fuse on the internal resistance can be studied.

[0071] In some specific implementations, referring to Figures 2 and 3, a mounting frame 10 can also be provided on the frame 1. The mounting frame 10 is mainly used to support and install the various mounting brackets 11. The mounting brackets 11 are set on the mounting frame 10, and their positions relative to the mounting frame 10 in the second direction are adjustable. By designing this structure, two adjacent mounting brackets 11 are placed on one mounting frame 10, providing a common reference target for adjusting the positions of the two adjacent mounting brackets 11 in the second direction. For example, if the top surface of the mounting frame 10 is a plane, the adjustment reference for the two adjacent mounting brackets 11 on the mounting frame 10 can be defined as the top surface of the mounting frame 10, making it easier to accurately adjust the height difference in the second direction.

[0072] The specific structural form of the mounting bracket 11 set on the mounting frame 10 is related to the adjustment method of the mounting bracket 11 relative to the mounting frame 10 in the second direction.

[0073] For example, the mounting bracket 11 is fixed to the top surface of the mounting frame 10 by fasteners. The top surface of the mounting frame 10 is designed with positioning holes, and the mounting bracket 11 is fixed to the corresponding positioning holes by fasteners. The adjustment method for the mounting bracket 11 relative to the mounting frame 10 in the second direction can be achieved by configuring adjusting shims 13 on the mounting bracket 11. The mounting height of the mounting bracket 11 on the mounting frame 10 can be adjusted by adjusting the shims 13, thereby making the mounting position of the mounting bracket 11 relative to the mounting frame 10 adjustable in the second direction. For example, the adjustment method for the mounting bracket 11 relative to the mounting frame 10 in the second direction can be achieved by increasing or decreasing the number of adjusting shims 13; or by replacing adjusting shims 13 with shims of different thicknesses; or by combining increasing or decreasing the number of adjusting shims 13 with replacing adjusting shims 13 with shims of different thicknesses. The thickness of the adjusting shim 13 can be selected according to actual needs. For example, it can include adjusting shims 13 with a thickness of 5mm or 10mm, etc., without specific limitations.

[0074] In another example, a lifting mechanism can be provided on the mounting frame 10, and the mounting bracket 11 is disposed at the lifting end of the lifting mechanism. The lifting end of the lifting mechanism can drive the mounting bracket 11 to move relative to the mounting frame 10 in a second direction to achieve position adjustment. Although specific drawings are not provided in this embodiment, it does not affect the understanding of the solution by those skilled in the art. The lifting mechanism can be, but is not limited to, a cylinder lifting mechanism, a lead screw lifting mechanism, a slide rail lifting mechanism combined with a locking mechanism (such as locking screw locking), etc. Any mechanism that can be known by those skilled in the art and can achieve the lifting function is acceptable, and no further specific limitations are made here.

[0075] In some other specific implementations, referring to Figures 2 and 3, at least two connecting brackets 14 can be provided on the frame 1. The two adjacent connecting brackets 14 are arranged opposite each other in the third direction. The two opposite ends of the mounting frame 10 in the third direction are respectively connected to the two adjacent connecting brackets 14. The connection position of the mounting frame 10 on the connecting brackets 14 is adjustable in the second direction. This allows the mounting frame 10 to be adjustable relative to the frame 1 along the height direction of the frame 1, thereby simulating the setting height of the device 2 under test. The first direction, the second direction, and the third direction are perpendicular to each other. Specifically, the second direction is the height direction of the frame 1. When the frame 1 is a rectangular frame, one of the first direction and the third direction can be the length direction of the frame 1, and the other is the width direction of the frame 1.

[0076] In a further implementation scheme, referring to Figure 3, the specific connection method between the mounting frame 10 and the connecting bracket 14 can be, but is not limited to, fastener connection. In this case, in order to ensure that the mounting frame 10 is adjustable relative to the frame 1 along the height direction of the frame 1, the connecting bracket 14 can be provided with connecting holes 140 spaced apart along the second direction. The connecting holes 140 are configured to be fixedly connected to the corresponding ends of the mounting frame 10. By fixing the mounting frame 10 to the connecting holes 140 at different heights, the height of the mounting frame 10 can be adjusted. The specific structural form of the connecting hole 140 can be, but is not limited to, round hole, square hole, oblong hole, etc. Alternatively, the connecting bracket 14 can be provided with a single first oblong hole, which is arranged along the second direction. The first oblong hole is used to be fixedly connected to the corresponding end of the mounting frame 10 by fasteners. By fixing the first oblong hole at different positions along the second direction, the height of the mounting frame 10 can also be adjusted.

[0077] In some specific implementations, referring to Figures 4 and 5, the mounting bracket 11 may specifically include a first clamping plate 111, a second clamping plate 112, and a fixing lead 113. The first clamping plate 111 and the second clamping plate 112 are arranged opposite to each other in a second direction. The first clamping plate 111 is disposed on the mounting frame 10 and can be fixed to the mounting frame 10 by fasteners. Specifically, the top surface of the mounting frame 10 is provided with mounting holes, and the first clamping plate 111 is fixed to the mounting holes by fasteners. The fixing lead 113 is mainly used to simulate the connection lead of the device under test 2. It has a first lead segment 1131 and a second lead segment 1132 connected to the first lead segment 1131. The first lead segment 1131 extends along a first direction, and the second lead segment 1132 extends along a second direction. The fixing part 12 is disposed at the end of the first lead segment 1131 away from the second lead segment 1132, and the first lead segment 1131 is clamped between the first clamping plate 111 and the second clamping plate 112. By designing this structural form, the clamping position of the first lead segment 1131 can be adjusted as needed, thereby adjusting the position of the fixing part 12 on the first lead segment 1131 in the first direction, which can better adapt to the fixing of the test equipment 2 of different length specifications. In addition, those skilled in the art should understand that the first clamping plate 111 and the second clamping plate 112 should both be designed as structural components with insulating functions to prevent leakage of current to the frame 1 through the first lead segment 1131 during the test. Specifically, it can be an insulating board, such as an epoxy resin insulating board.

[0078] Further referring to Figures 4 and 5, when the mounting bracket 11 is equipped with an adjusting shim 13, the adjusting shim 13 can be specifically positioned above the first clamping plate 111 in the second direction and below the first lead segment 1131. The adjusting shim 13 is generally made of a material with certain insulating properties.

[0079] In some specific implementations, referring to Figures 4 and 7, the aforementioned fixing part 12 can specifically be a first fixing hole 12' provided on the first lead segment 1131, and the end of the device under test 2 is provided with a second fixing hole 20 adapted to the first fixing hole 12'. The first fixing hole 12' and the second fixing hole 20 are fixedly connected by fasteners. The first fixing hole 12' can be constructed as an oblong hole extending along a first direction; the second fixing hole 20 can also be constructed as an oblong hole extending along the first direction; or, the first fixing hole 12' can be constructed as an oblong hole extending along the first direction, while the second fixing hole 20 is also constructed as an oblong hole extending along the first direction. This design allows for a certain adjustment margin between the first fixing hole 12' and the second fixing hole 20 at the end of the device under test 2, enabling a more accurate simulation of the actual installation conditions of the device under test 2. By designing the fixing part 12 as the aforementioned first fixing hole 12', not only can the device under test 2 be quickly disassembled and assembled, but it can also be adapted to the end fixing of various devices under test 2.

[0080] For example, the device under test 2 is a fuse. By designing the fixing part 12 as the first fixing hole 12' mentioned above, the fuse can be quickly installed and removed. Moreover, it can be adapted to the end fixing of various mainstream fuses, such as cylindrical fuses and knife fuses.

[0081] In some specific implementations, referring to Figures 6 and 7, an insulator 15 can be provided on the end face of the mounting frame 10 opposite to the second lead segment 1132 to ensure an insulating installation distance between the second lead segment 1132 and the mounting frame 10. The second lead segment 1132 is provided with a third fixing hole 1133 for fixed connection with the insulator 15, and the third fixing hole 1133 is constructed as a second waist-shaped hole extending along the second direction. By designing the second waist-shaped hole, the fixing position of the third fixing hole 1133 can be adaptively adjusted when the first clamping plate 111 and the first lead segment 1131 are adjusted by adding or removing the adjusting shims 13 or replacing the adjusting shims 13 of different thicknesses.

[0082] In some other specific embodiments, the frame 1 may also be provided with calibration scale lines arranged along the second direction. These calibration scale lines facilitate easier adjustment of the mounting bracket 11 relative to the frame 1 in the second direction. For example, they can indicate the mounting height of the mounting frame 10 on the frame 1, and also indicate the mounting height of the fixing part 12 on the mounting bracket 11. Furthermore, the mounting frame 10 may be provided with a level indicator. This level indicator helps to ensure the mounting frame 10 is installed horizontally during height adjustments. Although the calibration scale lines and level indicator are not shown in the accompanying drawings, this does not affect the understanding of the technical solution by those skilled in the art.

[0083] In some other specific embodiments, the fixing part 12 is adjustable in position relative to the frame 1 in the first direction. Specifically, the mounting bracket 11 as a whole may be adjustable in position in the first direction. For example, the mounting frame 10 may have holes arranged along the first direction, and the position of the mounting bracket 11 in the first direction can be adjusted by fixing it to different holes. Alternatively, the mounting bracket 11 may be directly fixed to a corresponding position on the frame beam of the frame 1, and the frame beam may have holes arranged along the first direction, and the position of the mounting bracket 11 in the first direction can be adjusted by fixing it to different holes. It may also be that the mounting bracket 11... The position of the fixing part 12 in the first direction is adjustable. For example, when the mounting bracket 11 is designed as a structure of a first clamping plate 111, a second clamping plate 112 and a fixing lead 113, the fixing part 12 on the fixing lead 113 can be adjusted in the first direction by clamping the fixing lead 113 at different positions by the first clamping plate 111 and the second clamping plate 112. If the second lead segment 1132 needs to be fixed to the mounting frame 10, it needs to be replaced with an insulator 15 of the corresponding specification, or insulating pads can be added or removed on the end side of an insulator 15 of a certain specification to ensure the stability of the fixation.

[0084] On the other hand, this application embodiment also provides a testing device, including a mounting simulation fixture and a housing 16. The mounting simulation fixture is the same as described in any of the above embodiments. The housing 16 surrounds the frame 1 of the mounting simulation fixture. The housing 16 is mainly used to protect the frame 1, the mounting bracket 11 mounted on the frame 1, and the device under test 2 mounted on the mounting bracket 11. A test interface 3 is provided on the housing 16, and the test interface 3 is electrically connected to the device under test. By connecting the test interface 3 to a test-related loading device, corresponding tests can be completed. For example, by connecting the test interface 3 to a current-related loading device, current and resistance-related tests of the device under test 2 can be achieved. Since the aforementioned mounting simulation fixture has the above-mentioned technical effects, the testing device with this mounting simulation fixture should also have corresponding technical effects, which will not be elaborated further here.

[0085] Referring to Figure 1, the aforementioned housing 16 may specifically include a circumferential enclosure 161 and a top enclosure 162 surrounding the frame 1. The circumferential enclosure 161 may be, but is not limited to, four enclosures connected end to end, and its specific structure is adapted to the structural form of the frame 1. For example, when the frame 1 adopts a cuboid or cube frame structure, the corresponding circumferential enclosure 161 is formed by four enclosures, and the top enclosure 162 is located on the top of the frame 1.

[0086] To ensure the safety of the testing device, both the circumferential enclosure 161 and the top enclosure 162 can be made of insulating materials; alternatively, both the surface of the circumferential enclosure 161 and the surface of the top enclosure 162 can be provided with an insulating protective layer, which can specifically have a certain leakage protection function and an arc shielding function; or, both the circumferential enclosure 161 and the top enclosure 162 can be made of insulating materials, and an insulating protective layer can be provided on the surface of both the circumferential enclosure 161 and the top enclosure 162. This design can achieve better protection, such as achieving a leakage current ≤0.1mA during 1000A current testing.

[0087] Referring again to Figure 1, the bottom of the frame 1 can also be provided with a set of wheels 17. This design makes it easier to move the test device and allows it to be moved to the required location as needed.

[0088] In addition, in order to facilitate observation of the status of the device under test 2 during the test, and also to ensure the safety of operation and detect potential safety hazards in a timely manner, an observation window 163 can be provided on the top panel 162. The observation window 163 can be an open structure or a cover structure made of transparent material, such as a cover structure made of colorless transparent acrylic material. In actual application, the configuration can be selected according to actual needs, and no specific limitation is made here.

[0089] In addition, to facilitate the installation and removal of the device under test 2, at least one side of the circumferential enclosure 161 may be provided with an openable and closable door panel 164. For example, at least one side of the circumferential enclosure 161 may be designed to be magnetically attached to the frame 1. Of course, the top enclosure 162 may also be designed to be magnetically attached to the frame 1. Alternatively, at least one side of the circumferential enclosure 161 may be designed with a door panel structure connected by a hinge, which can perform opening and closing actions as needed.

[0090] When configuring the aforementioned walking wheel set 17, observation window 163, and door panel 164, the testing device can choose to configure one of them, two of them, or all three of them simultaneously, depending on actual needs. No specific limitations are made here.

[0091] To enable those skilled in the art to better understand the specific structure of the testing device, a brief description of the relevant tests is given below, using the device under test 2 as an example of a fuse:

[0092] Test interface 3 may specifically include a temperature acquisition interface, a current input interface, and a current output interface. The current input interface and the current output interface are used to connect to the two ends of the fuse, respectively. By connecting the current input interface and the current output interface to an external power supply device, the internal resistance of the fuse can be tested. For example, the reliability of the fuse can be evaluated based on the rate of change of internal resistance, and its performance under different height difference conditions can be judged.

[0093] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0094] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "a," and / or "the" are not specifically singular and may include the plural.
