Description

Technical Field

[0001] The present application relates to the technical field of testing equipment, and in particular to a test equipment for an energy storage type electric operator for a molded case circuit breaker. Background Art

[0002] Molded case circuit breakers, also known as device-type circuit breakers, are a common protective circuit component. All of their components are sealed in a plastic casing, with auxiliary contacts, undervoltage releases, and shunt releases often modularized. Due to their extremely compact structure, molded case circuit breakers are virtually impossible to repair. To maintain reliable electrical contact and prevent contact bounce caused by false connections or electrostatic repulsion during transient short-circuit current surges, molded case circuit breakers undergo various tests after initial manufacturing. These tests primarily include visual inspection, mechanical performance testing, withstand voltage testing, and pressure alignment testing to ensure safe and reliable operation.

[0003] Existing molded case circuit breaker testing equipment can usually only perform a single test. After completing a test of a circuit breaker, workers need to remove the circuit breaker from the fixture on the test equipment, transfer it to the next test equipment and fix it. When the number of molded case circuit breakers increases, the molded case circuit breakers need to be transferred and fixed frequently, which prolongs the test time of the molded case circuit breaker and reduces the test efficiency, which is an obvious shortcoming. Utility Model Content

[0004] In order to improve the testing efficiency of molded case circuit breakers, the present application provides a test device for a molded case circuit breaker using an energy storage type electric operator.

[0005] The present application provides a test device for an energy storage type electric actuator for a molded case circuit breaker using the following technical solution:

[0006] A test device for an energy storage type electric operator for a molded case circuit breaker includes a test bench and a frame. The test bench is provided with a plurality of test stations, each of which is provided with:

[0007] A fixing plate, the test bench is provided with a groove that slides with the fixing plate, and the fixing plate is provided with a fixing assembly for fixing the circuit breaker;

[0008] A flip switching mechanism, wherein the flip switching mechanism includes a horizontal guide rail horizontally arranged in the groove, a vertical guide rail perpendicular to the horizontal guide rail is provided on the frame, a first guide shaft is slidably connected to the vertical guide rail, a second guide shaft is slidably connected to the horizontal guide rail, both ends of the fixed plate are hinged on the first guide shaft and the second guide shaft respectively, a rodless cylinder is provided on the test bench, the length direction of the rodless cylinder is parallel to the length direction of the horizontal guide rail, and the second guide shaft is fixedly connected to the moving part of the rodless cylinder;

[0009] A voltage grading mechanism, the voltage grading mechanism is used to switch the voltage of the circuit breaker test circuit;

[0010] A pressure test alignment mechanism, which is used to test the closing force of the circuit breaker closing button;

[0011] A barcode scanner gun is used to scan and record test data of electrical control products.

[0012] By adopting the above technical solution, during the test, the worker fixes the circuit breaker on the fixed plate through the fixing component, and then uses the barcode scanner to record the circuit breaker product data. After the recording is completed, the worker performs an appearance inspection and a mechanical operation performance test on the circuit breaker. After the two tests are completed, the worker starts the rodless cylinder to drive the second guide shaft to move along the length direction of the horizontal guide rail. The second guide shaft drives one end of the fixed plate to move toward the vertical guide rail, and the other end of the fixed plate rises vertically along the vertical guide rail. When the fixed plate is vertically set on the test bench, the rodless cylinder is closed. At this time, the circuit breaker is subjected to a withstand voltage test, a step voltage test and a pressure alignment test. After the test is completed, the flip switching mechanism drives the fixed plate back to the horizontal initial position, and the worker removes the tested circuit breaker. The setting of the flip switching mechanism realizes the automatic switching of the test position of the circuit breaker on the same test equipment, so that the circuit breaker can complete multiple test contents on one test equipment, saving the transfer and fixing time of the circuit breaker, thereby improving the testing efficiency of the circuit breaker.

[0013] Optionally, the voltage grading mechanism includes a mounting plate arranged in the test bench, a plurality of bases are arranged at intervals on the mounting plate, a plurality of copper pillars are fixed to nylon on the surface of each base through copper pillars, a cylinder is arranged under each base, the cylinder is arranged on the surface of the mounting plate, the output shaft of the cylinder is fixedly connected to a push plate, and probes corresponding to the plurality of copper pillars are arranged on the push plate, the probes are arranged directly below the copper pillars, and when the probes contact the copper pillars, the test circuit is closed.

[0014] By adopting the above technical solution, when conducting a graded voltage test, the worker controls the cylinder to drive the push plate to move toward the copper column. When the probe contacts the copper column, the test circuit is closed and energized. When the cylinder drives the push rod away from the copper column to separate the probe from the copper column, the test circuit is disconnected. This setting realizes the graded voltage power supply to the test circuit.

[0015] Optionally, the pressure test alignment mechanism includes an X-axis adjustment guide rail arranged on the frame, a connecting block is slidably connected to the X-axis adjustment guide rail, a Y-axis adjustment shaft is provided on the connecting block, a guide shaft support is slidably sleeved on the Y-axis adjustment shaft, a locking assembly is provided on the guide shaft support, a Z-axis adjustment rail is connected to the guide shaft support through a quick adjustment guide rail fixing clamp, and a pressure testing machine is provided at the bottom end of the Z-axis adjustment guide rail.

[0016] By adopting the above technical solution, when a pressure alignment test is required, the control system controls the connecting block to move along the X-axis adjustment guide rail, and the movement of the connecting block drives the Y-axis adjustment shaft to move to the specified position. Then the worker slides the guide shaft support to the specified position and locks the guide shaft support through the locking assembly. After locking, the quick adjustment guide rail fixing clamp is loosened. At this time, the Z-axis adjustment guide rail can move in the vertical direction and drive the pressure testing machine to move. When the pressure testing machine moves to be precisely aligned with the closing button of the circuit breaker, a pressure alignment test is performed. The setting of the pressure test alignment mechanism realizes the flexible adjustment of the position of the pressure testing machine, so that the pressure testing machine can be accurately aligned with the closing button of the circuit breaker, thereby improving the accuracy of the pressure alignment test.

[0017] Optionally, a plurality of locking holes are opened in the axial direction of the Y-axis adjustment shaft, a locking column is slidably connected in the guide shaft support and plugged into the locking hole, a threaded column is threadedly connected in the guide shaft support, a rotating handle is provided at the top of the threaded column, and the bottom end of the threaded column is coaxially fixedly connected to the locking column.

[0018] By adopting the above technical solution, after the guide shaft support moves to the specified position, the worker turns the rotating handle, and the rotating handle drives the threaded column to rotate. When the threaded column rotates, it drives the locking column to move toward the locking hole. When the bottom surface of the locking column abuts against the bottom wall of the locking hole, the guide shaft support is fixed on the Y-axis adjustment column. This setting realizes the locking of the position of the pressure testing machine, reduces the possibility of position deviation of the pressure testing machine during the test, and thus ensures the smooth progress of the pressure alignment test.

[0019] Optionally, the fixing assembly includes a quick-change plate arranged on the fixing plate, the quick-change plate is provided with a positioning block adapted to the circuit breaker, the quick-change plate is provided with a clamping guide rail, the clamping guide rail is slidably connected to the clamping block, the quick-change plate is provided with a mounting seat, the mounting seat is provided with a guide seat, a push rod is slidably connected in the guide seat, and the push rod is provided with a clamping block at one end facing the clamping block, the clamping block is provided with a clamping groove, the clamping block is clamped in the clamping groove, and the push rod is hinged with a pushing handle at one end away from the clamping block, and a compression spring is sleeved on the push rod, one end of the compression spring is connected to the push rod, and the other end is connected to the guide seat, and when the push rod moves toward the clamping block, the compression spring is compressed.

[0020] By adopting the above technical solution, when fixing the circuit breaker, the worker turns the push handle clockwise, and the push handle drives the push rod to move toward the clamping block. During the movement of the push rod, the compression spring is gradually compressed, and the gap between the clamping block and the positioning block becomes larger. At this time, the worker places the circuit breaker on the positioning block, and then cancels the force on the push handle. The pressure on the compression spring disappears, and the compression spring resets to push the push rod in the direction away from the clamping block. The push rod drives the clamping block to move in the direction close to the positioning block. When the clamping surface of the clamping block abuts the edge of the circuit breaker, the fixing operation of the circuit breaker is completed. This arrangement realizes the fixation of the circuit breaker, avoids the phenomenon of the circuit breaker being separated from the fixed plate when switching the test position, and ensures the smooth progress of the test process.

[0021] Optionally, the quick-change plate is detachably connected to the fixed plate via connecting bolts, and handles are provided on opposite sides of the quick-change plate.

[0022] By adopting the above technical solution, when the fixing assembly on the quick-change plate fails or a circuit breaker of another size needs to be fixed, workers can replace the fixing plate by disassembling and installing the connecting bolts to ensure that the fixing assembly can fix the circuit breaker effectively.

[0023] Optionally, an accordion cover is provided at one end of the groove away from the vertical guide rail, one end of the accordion cover is connected to the inner wall of the groove, and the other end is connected to the fixing plate.

[0024] By adopting the above technical solution, when the second guide shaft drives the fixed plate to move, the accordion cover expands or contracts in the groove. Under the connecting action of the accordion cover, the operation of the fixed plate is more stable, reducing the damage to the circuit breaker caused by unstable movement.

[0025] Optionally, a plurality of cooling fans are provided on opposite side walls of the test bench.

[0029] 2. This application fixes the circuit breaker by setting a fixing component, which prevents the circuit breaker from being separated from the fixing plate when switching the test position, thereby ensuring the smooth progress of the test process. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a test device for an energy storage type electric operator for a molded case circuit breaker.

[0038] Reference Figure 1 A test device for an energy storage type electric operator for a molded case circuit breaker includes a test bench 01 and a rack 02. The rack 02 is fixedly installed above the test bench 01. A plurality of test stations are provided on the test bench 01. In this embodiment, there are two test stations, which are respectively arranged on both sides of the test bench 01. Each test station is provided with a fixed plate 1, a flip switching mechanism 2, a voltage grading mechanism 3, a pressure test alignment mechanism 4 and a barcode scanning gun 5.

[0039] Referring to the figure, multiple cooling fans (not shown in the figure) are fixedly installed on the opposite sides of the test bench 01. The cooling fans can accelerate the air flow inside the test bench 01, take away the heat generated by the operation of the heating equipment, keep the electronic components inside the test bench 01 working within a suitable temperature range, and improve the service life of the test bench 01.

[0040] Reference Figure 2 and Figure 3The test bench 01 is provided with grooves 011 corresponding to the two fixed plates 1 one by one. The fixed plates 1 are slidably connected inside the grooves 011. A fixing assembly 6 for fixing the circuit breaker is provided on the fixed plate 1. The fixing assembly 6 includes a quick-change plate 61 detachably connected to the fixed plate 1 by a connecting bolt 611. The opposite sides of the quick-change plate 61 are fixedly connected with handles 612. When the quick-change plate 61 needs to be replaced, the worker removes the connecting bolt 611 and lifts the handle 612 to remove the quick-change plate 61 from the fixed plate 1.

[0041] Reference Figure 3 The quick-change plate 61 is fixedly connected to a positioning block 62 that matches the bottom surface of the circuit breaker. One end of the quick-change plate 61 is fixedly connected to a clamping guide rail 63. A clamping block 64 is slidably connected to the clamping guide rail 63. A mounting seat 65 is fixedly connected to the side of the quick-change plate 61 close to the clamping block 64. A guide seat 66 is fixedly connected to the mounting seat 65. A push rod 67 is slidably connected to the guide seat 66. The sliding direction of the push rod 67 is perpendicular to the length direction of the clamping block 64. The push rod 67 is fixedly connected to one end of the clamping block 64. It is connected to a clamping block 671, and a clamping groove 641 is provided on the clamping block 64 to engage with the clamping block 671. The end of the push rod 67 away from the clamping block 671 is hinged with a pushing handle 68. The worker realizes the sliding of the push rod 67 in the guide seat 66 by turning the pushing handle 68. A compression spring 69 is provided on the push rod 67, one end of the compression spring 69 is fixedly connected to the push rod 67, and the other end is fixedly connected to the guide seat 66. When the push rod 67 moves toward the clamping block 64, the compression spring 69 is compressed.

[0042] When testing is required, the worker turns the pushing handle 68 clockwise, and the pushing handle 68 drives the push rod to move toward the clamping block 64. During the movement of the push rod, the compression spring 69 is gradually compressed, and the gap between the clamping block 64 and the positioning block 62 becomes larger. At this time, the worker places the circuit breaker on the positioning block 62, cancels the force on the pushing handle 68, and the pressure on the compression spring 69 disappears. The compression spring 69 resets and pushes the push rod in the direction away from the clamping block 64. The push rod drives the clamping block 64 to move in the direction close to the positioning block 62. When the clamping surface of the clamping block 64 abuts the edge of the circuit breaker, the fixing operation of the circuit breaker is completed. After the fixing is completed, the worker records the circuit breaker product data through the barcode scanning gun 5. After the recording is completed, the worker performs an appearance inspection and a mechanical operation performance test on the circuit breaker.

[0043] The setting of the fixing assembly 6 fixes the circuit breaker on the fixing plate 1, thereby preventing the circuit breaker from being displaced or separated from the fixing plate 1 during the test process, thereby ensuring the smooth progress of the test process.

[0044] Reference Figure 2 and Figure 3The flip switching structure includes a horizontal guide rail 21 fixedly installed in the groove 011, and the length direction of the horizontal guide rail 21 is parallel to the width direction of the groove 011. A vertical guide rail 22 perpendicular to the horizontal guide rail 21 is fixedly installed on the frame 02, and a first guide shaft 23 is slidably connected to the vertical guide rail 22, and a second guide shaft 24 is slidably connected to the horizontal guide rail 21. The two ends of the fixed plate 1 are respectively hinged on the first guide shaft 23 and the second guide shaft 24. A rodless cylinder 25 is fixedly installed inside the groove 011, and the length direction of the rodless cylinder 25 is parallel to the length direction of the horizontal guide rail 21. The second guide shaft 24 is fixedly connected to the moving part of the rodless cylinder 25.

[0045] Reference Figure 2 and Figure 3 The end of the groove 011 away from the vertical guide rail 22 is provided with an accordion cover 7. One end of the accordion cover 7 is fixedly connected to the inner wall of the groove 011, and the other end is fixedly connected to the fixed plate 1. When the second guide shaft 24 drives the fixed plate 1 to move, the accordion cover 7 expands or contracts in the groove 011. Under the connection of the accordion cover 7, the operation of the fixed plate 1 is more stable, reducing the damage to the circuit breaker caused by unstable movement.

[0046] When the circuit breaker is tested in the horizontal test position, the worker starts the rodless cylinder 25, which drives the second guide shaft 24 to move along the length direction of the horizontal guide rail 21. The second guide shaft 24 drives one end of the fixed plate 1 to move toward the vertical guide rail 22, and the other end of the fixed plate 1 rises vertically along the vertical guide rail 22. When the fixed plate 1 is vertically set on the test bench 01, the rodless cylinder 25 is closed. At this time, the circuit breaker is switched from the horizontal test position to the vertical test position, and the worker performs subsequent withstand voltage test, step voltage test and pressure test on the circuit breaker. After the test is completed, the rodless cylinder 25 is started again. The rodless cylinder 25 drives the second guide shaft 24 to move away from the vertical guide rail 22 through the mounting block. The second guide shaft 24 drives the fixing plate 1 back to the horizontal initial position. The worker removes the circuit breaker after the test. The setting of the flip switching mechanism 2 realizes the automatic switching of the test position of the circuit breaker on the same test equipment, so that the circuit breaker can complete multiple test contents on one test equipment, saving the transfer and fixing time of the circuit breaker, thereby improving the testing efficiency of the circuit breaker.

[0047] Reference Figure 4The voltage grading mechanism 3 includes a mounting plate 31 fixedly mounted in the test bench 01, and a plurality of bases 32 are arranged at intervals on the top surface of the mounting plate 31. In this embodiment, the number of the bases 32 is three, and the device of the utility model has three-speed voltage adjustment. The surface of each base 32 is fixedly connected to a plurality of copper pillars 34 through copper pillar fixing nylon 33. A cylinder 35 is arranged directly below each base 32, and the cylinder 35 is fixedly mounted on the surface of the mounting plate 31. The output shaft of each cylinder 35 is fixedly connected to a push plate 36, and a probe 37 corresponding to the plurality of copper pillars 34 is fixedly connected to the push plate 36. The probe 37 is arranged directly below the copper pillar 34. When the cylinder 35 drives the push plate 36 to move toward the copper pillar 34 and the probe 37 contacts the copper pillar 34, the test circuit is closed and energized. When the cylinder 35 drives the push rod away from the copper pillar 34 to disengage the probe 37 from the copper pillar 34, the test circuit is disconnected. Such an arrangement realizes the supply of graded voltage to the test circuit.

[0048] Reference Figure 2 and Figure 4 The test bench 01 is equipped with control buttons 38 corresponding to three cylinders 35. When the control button 38 is pressed, the cylinder 35 controlled by the control button 38 pushes the push plate 36 toward the copper column 34. When the circuit breaker is switched to the vertical test position, the worker performs a step voltage test on the circuit breaker by pressing the control button 38 in sequence.

[0049] Reference Figure 1 and Figure 5 The pressure test alignment mechanism 4 includes an X-axis adjustment guide rail 41 fixedly connected to the frame 02, a connecting block 42 is slidably connected to the X-axis adjustment guide rail 41, a Y-axis adjustment shaft 43 is fixedly connected to the connecting block 42, the Y-axis adjustment shaft 43 is perpendicular to the X-axis adjustment shaft, a guide shaft support 44 is slidably sleeved on the Y-axis adjustment shaft 43, a locking assembly 8 is provided on the guide shaft support 44, a Z-axis adjustment guide rail 46 is connected to the guide shaft support 44 through a quick adjustment guide rail fixing clamp 45, and the bottom end of the Z-axis adjustment guide rail 46 is fixedly connected to a pressure testing machine 47.

[0050] Reference Figure 1 and Figure 5 A plurality of locking holes 431 are provided in the axial direction of the Y-axis adjustment shaft 43. The locking assembly 8 includes a locking column 81 slidably connected to the guide shaft support 44. The bottom end of the locking column 81 is plugged into the locking hole 431. A threaded column 82 is connected to the inner thread of the guide shaft support 44. The top end of the threaded column 82 is fixedly connected to a rotating handle 83. The bottom end of the threaded column 82 is coaxially fixedly connected to the locking column 81.

[0051] When a pressure alignment test is required, the control system controls the connecting block 42 to move along the X-axis adjustment guide rail 41. The movement of the connecting block 42 drives the Y-axis adjustment shaft 43 to move to the specified position. The worker slides the guide shaft support 44 to the specified position. Then the worker turns the rotating handle 83, and the rotating handle 83 drives the threaded column 82 to rotate. When the threaded column 82 rotates, it drives the locking column 81 to move toward the locking hole 431. When the bottom surface of the locking column 81 abuts against the bottom wall of the locking hole 431, the guide shaft support 44 is fixed on the Y-axis adjustment column. After locking is completed, the quick adjustment guide rail fixing clamp 45 is loosened. At this time, the Z-axis adjustment guide rail 46 can move in the vertical direction and drive the pressure testing machine 47 to move. When the pressure testing machine 47 moves to be precisely aligned with the closing button of the circuit breaker, a pressure alignment test is performed. The setting of the pressure test alignment mechanism 4 realizes the flexible adjustment of the position of the pressure testing machine 47, so that the pressure testing machine 47 can be accurately aligned with the closing button of the circuit breaker, thereby improving the accuracy of the pressure alignment test.

[0052] The implementation principle of the test equipment of the energy storage type electric operation for the molded case circuit breaker of the embodiment of the present application is as follows: during the test, the worker fixes the circuit breaker on the fixed plate 1 through the fixing component 6, and then uses the barcode scanner 5 to record the product data of the circuit breaker. After the recording is completed, the worker performs an appearance inspection and a mechanical operation performance test on the circuit breaker. After the two tests are completed, the worker starts the rodless cylinder 25, and the rodless cylinder 25 drives the second guide shaft 24 to move along the length direction of the horizontal guide rail 21. The second guide shaft 24 drives one end of the fixed plate 1 to move toward the vertical guide rail 22, and the other end of the fixed plate 1 moves along the vertical guide rail 22. The guide rail 22 rises vertically. When the fixed plate 1 is vertically set on the test bench 01, the rodless cylinder 25 is closed. At this time, the circuit breaker's withstand voltage test, step voltage test and pressure alignment test are carried out. After the test is completed, the flip switching mechanism 2 drives the fixed plate 1 back to the horizontal initial position. The worker removes the tested circuit breaker. The setting of the flip switching mechanism 2 realizes the automatic switching of the test position of the circuit breaker on the same test equipment, so that the circuit breaker can complete multiple test contents on one test equipment, saving the transfer and fixing time of the circuit breaker, thereby improving the testing efficiency of the circuit breaker.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
