Description

Technical Field

[0001] The present invention relates to the technology of circuit breaker detection, and particularly to a new type of complete set of test devices for draw-out circuit breakers. Background Art

[0002] Draw-out circuit breakers are generally used in medium-voltage switchgear. Due to the presence of draw-out circuit breakers, medium-voltage switchgear is also called draw-out high-voltage switchgear. Circuit breakers can not only break and close normal load operating current, but also break and close rated short-circuit current. Therefore, circuit breakers are often used in cooperation with components such as relays to automatically cut off the overload or short-circuit current in the fault circuit.

[0003] In the Chinese invention patent with the publication number CN112485658A, a test device for draw-out circuit breakers is disclosed. By adjusting the distance between the first insulating plate and the second insulating plate, the vertical distance between the combined static contact assemblies on the first insulating plate and the combined static contact assemblies on the second insulating plate can be adjusted. Since the multiple combined static contact assemblies on the first insulating plate and the multiple combined static contact assemblies on the second insulating plate can all move along the axis perpendicular to the support assembly, it is convenient to adjust the distance between the multiple combined static contact assemblies on the first insulating plate and the distance between the multiple combined static contact assemblies on the second insulating plate. Furthermore, the overall device can be applicable to draw-out circuit breakers with different phase spacings and pole spacings, effectively improving the versatility.

[0004] When the existing equipment is in use, due to the insufficient mastery of the test method by the staff or the improper operation of the test equipment, the test data is abnormal and inaccurate, and even potential hidden dangers are buried for the draw-out circuit breaker, resulting in misjudgment of the state of the draw-out circuit breaker. At the same time, when docking with the circuit breaker, it is impossible to accurately dock with the connection end, making it easy to have poor contact at the connection, resulting in deviation of the overall detection result. Therefore, a new type of complete set of test devices for draw-out circuit breakers has been developed. Summary of the Invention

[0036] Embodiment: Please refer to Figures 1 - 8 , a new type of complete set of test devices for a handcart circuit breaker, including a base 1. A partition block 11 is arranged at the upper end of the base 1. At the same time, a slider 12 is slidably installed at the upper end of the partition block 11. A first fixing plate 13 is arranged at the upper end of the slider 12. A telescopic member 14 is arranged at the upper end of the first fixing plate 13. A second fixing plate 15 is arranged at the upper end of the telescopic member 14. Guide grooves 16 are provided at the ends of the first fixing plate 13 and the second fixing plate 15.

[0037] In this solution, the telescopic member 14 is composed of a round rod, a cylinder and a spring. A spring is arranged on the inner wall of the cylinder. At the same time, the inner wall of the cylinder is slidably connected to the outer surface of the round rod, and the end of the round rod is in contact with the spring. Thus, when the second fixing plate 15 moves, the position can be adjusted by the movement of the round rod to make it suitable for the current scenario.

[0038] The guide grooves 16 are used to adjust the position of the adjusting assembly 3. Furthermore, when facing handcart circuit breakers of different specifications, they can all be detected, reducing the time for replacing the detection equipment.

[0039] Furthermore, a leveling assembly 2 is assembled on one side of the base 1 to position the handcart circuit breaker through the leveling assembly 2; wherein, the leveling assembly 2 includes a fixing block 21 connected to the base 1. Positioning plates 22 are symmetrically arranged at the ends of the fixing block 21. At the same time, a rotating cylinder 23 is slidably installed between the positioning plates 22. An activity groove 231 is provided on the outer surface of the rotating cylinder 23, and a convex block 232 is slidably installed on the inner wall of the activity groove 231.

[0040] In this embodiment, elastic components such as springs are provided at both ends of the rotary drum 23, and the other ends of the springs are connected to the positioning plate 22. Rotary blocks are provided at both ends of the rotary drum 23, and the outer surface of the rotary block is rotatably connected to the inner wall of the positioning plate 22. Thus, when the rotary drum 23 moves, the rotary drum 23 is supported by the spring.

[0041] At the same time, one end of the rotary drum 23 penetrates and extends to the outside of the positioning plate 22. By rotating the rotary drum 23 and cooperating with the movable slot 231, the convex block 232 can be driven to move. Additionally, a device with power output such as a motor can be provided at the end of the rotary drum 23 and connected to an external control device.

[0042] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which consists of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low power consumption.

[0043] Furthermore, a rotating shaft 24 is rotatably installed at the lower end of the fixed block 21. An adjusting block 25 is provided at the end of the rotating shaft 24. At the same time, the end of the adjusting block 25 is connected to the outer surface of the convex block 232.

[0044] Specifically, since the adjusting block 25 is connected to the convex block 232, when the rotary drum 23 rotates or moves, the adjusting block 25 is synchronously driven to swing. The adjusting block 25 is fixedly connected to the rotating shaft 24, so that the rotating shaft 24 rotates synchronously with the adjusting block 25.

[0045] Furthermore, a swing plate 26 is provided at the end of the rotating shaft 24 away from the adjusting block 25. Driving blocks 27 are rotatably installed at both ends of the swing plate 26. An active block 271 is provided at the upper end of the driving block 27. An active member 28 is provided at the upper end of the active block 271. A support plate 29 is provided at the upper end of the active member 28. The outer surface of the active block 271 is slidably connected to the outer surface of the positioning plate 22.

[0046] Specifically, when the rotating shaft 24 rotates, the swing plate 26 is synchronously driven to rotate, thereby driving the driving block 27 rotatably installed at the end of the swing plate 26 to move. At the same time, an active block 271 is provided at the end of the driving block 27, and since the outer surface of the active block 271 is slidably connected to the outer surface of the positioning plate 22, the overall stability of the active block 271 is ensured during operation.

[0047] The movable part 28 is a telescopic rod or other device with a telescopic function, and an elastic component such as a spring is arranged on the outer surface of the telescopic rod. The movable part 28 supports the tray 29, so that when the tray 29 is in contact with the handcart circuit breaker, there will be no sliding, and thus before the handcart circuit breaker is docked, it is calibrated, which is convenient for subsequent docking detection.

[0048] Further, the adjusting component 3 is assembled on the inner wall of the guiding groove 16, and the connecting end is adjusted through the adjusting component 3; the adjusting component 3 includes a baffle 31, and a guiding cylinder 32 is arranged between the positions of the baffle 31. The outer surface of the guiding cylinder 32 is slidably connected with the inner wall of the guiding groove 16.

[0049] In this embodiment, the guiding cylinder 32 is used for docking the connection part of the handcart circuit breaker, and at the same time, it is partitioned by the baffle 31. A circular ring is arranged on the outer surface of the baffle 32, and the outer surface of the circular ring is attached to the outer surface of the first fixing plate 13.

[0050] By slidably arranging the guiding cylinder 32 on the inner wall of the guiding groove 16, when detecting different models of handcart circuit breakers, the position of each guiding cylinder 32 can be adjusted in real time according to the actual situation to make it applicable to the current scenario.

[0051] Further, a fixing rod 311 is arranged at the end of the baffle 31, and the end of the fixing rod 311 penetrates and extends to the other end of the baffle 31. At the same time, a pull rod 312 is arranged at the end of the fixing rod 311.

[0052] Specifically, the fixing rod 311 can be driven to move through the pull rod 312, so that when it is necessary to move, the limiting block 37 is separated from the first fixing plate 13, which is convenient for the operator to move the guiding cylinder 32.

[0053] Further, positioning blocks 33 are arranged at the lower end of the baffle 31 and on both sides of the guiding cylinder 32. A plurality of through holes 331 are formed on the outer surface of the positioning blocks 33, and the plurality of through holes 331 are evenly distributed on the outer surface of the positioning blocks 33. A slot hole 34 is formed at the lower end of the positioning block 33, and a protective block 35 is slidably installed on the inner wall of the slot hole 34, and the protective block 35 is located in the inner cavity of the positioning block 33.

[0054] Specifically, when the protective block 35 moves, it is limited by the slot hole 34, so that the protective block 35 stably moves along the inner wall of the slot hole 34, effectively reducing the situation of falling off. The inner cavity of the positioning block 33 is communicated with the outside through the through holes 331.

[0055] Further, the inner wall of the protective block 35 is connected to the outer surface of the fixing rod 311. Meanwhile, an elastic member 351 is provided at the end of the protective block 35, and the upper end of the elastic member 351 is connected to the inner wall of the baffle 31. A connecting block 352 corresponding to the through hole 331 is provided on the outer surface of the protective block 35, and a push rod 36 is rotatably installed at the end of the connecting block 352.

[0056] Specifically, the elastic member 351 is an elastic component such as a spring, and is also used to support the protective block 35, so that the whole protective block 35 remains stable and tightly presses against the inner wall of the positioning block 33.

[0057] Meanwhile, when the protective block 35 moves, it synchronously drives the connecting block 352 provided on its outer surface to move. Since the push rod 36 is rotatably installed at the end of the connecting block 352, when the connecting block 352 moves, the push rod 36 is driven to move.

[0058] Further, a limiting block 37 is rotatably installed at the end of the push rod 36 away from the connecting block 352. Meanwhile, a limiting rod 38 is rotatably installed at the middle position of the limiting block 37, and the end of the limiting rod 38 is fixedly connected to the outer surface of the positioning block 33. The end of the limiting block 37 is attached to the outer surface of the first fixing plate 13.

[0059] Specifically, when the push rod 36 moves, it synchronously drives the limiting block 37 rotatably installed at its end to move. The limiting block 37 is supported by the limiting rod 38, so that when the limiting block 37 is stressed, it rotates around the limiting rod 38, thereby moving the end of the limiting block 37 away from the push rod 36, so that the limiting block 37 fits or separates from the first fixing plate 13.

[0060] An anti-slip component such as a rubber block is rotatably installed at the end of the limiting block 37, and it moves synchronously with the limiting block 37 to ensure the stability during positioning.

[0061] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
