[0003] Currently, withstand voltage testing of individual circuit breakers is generally performed manually, which is inefficient and unsuitable for large-scale testing. Furthermore, withstand voltage testing is conducted under high pressure, posing a safety hazard to workers. While some withstand voltage testing devices are available to assist manual testing, these devices can only check the withstand voltage of the circuit breaker terminals and do not have the function of testing the withstand voltage of the circuit breaker rivets.

[0060] Circuit breakers need to undergo withstand voltage testing before leaving the factory to ensure insulation and safety.

[0061] like Figure 1 As shown, the circuit breaker 10 generally includes a handle 11, multiple terminals 12, multiple rivets 13, and multiple power outlets 14. The handle 11 and the multiple terminals 12 are located on the same side of the circuit breaker 10, the multiple power outlets 14 are located on the side of the circuit breaker 10 opposite to the handle 11, and the multiple rivets 13 are located on the side of the circuit breaker 10 adjacent to both the handle 11 and the power outlets 14.

[0062] This embodiment provides a circuit breaker withstand voltage testing device that can simultaneously perform withstand voltage testing on the terminals 12 and rivets 13 of the circuit breaker 10, improving the diversity and efficiency of testing functions, and also helping to improve the safety of workers.

[0063] Specifically, such as Figures 2-12As shown, the circuit breaker withstand voltage testing device includes a base 100, a positioning mechanism 200, a rivet detection mechanism 300, a terminal detection mechanism 400, and a handle operation mechanism 500.

[0064] The base 100 is provided with a high-voltage contact plate 110 and a ground contact plate 120, which are used to make contact electrical connections with the high-voltage end and the ground end of the withstand voltage equipment, respectively.

[0065] A positioning mechanism 200 is disposed on the base 100. The positioning mechanism 200 includes a mounting space 201 for mounting the circuit breaker 10 and a first probe group 230. The mounting space 201 has a side opening and a top opening. The side opening corresponds to the handle 11 and a plurality of terminals 12, and the top opening corresponds to a plurality of rivets 13. The first probe group 230 is used to electrically connect a plurality of plug ports 14 to the high-voltage contact plate 110. Optionally, the first probe group 230 includes a plurality of first probes, each corresponding one-to-one with a plug port 14. For example, if the circuit breaker 10 includes four plug ports 14, then the first probe group 230 includes four first probes. Optionally, the first probes can be electrically connected to the plug ports 14 by plugging them in.

[0066] The rivet detection mechanism 300 includes a first drive assembly 310 disposed on a base 100 and a second probe group 320 connected to the output end of the first drive assembly 310. The second probe group 320 is disposed above a top opening and electrically connected to a ground contact plate 120. The first drive assembly 310 drives the second probe group 320 to descend and make contact with a plurality of rivets 13. Optionally, the second probe group 320 includes a plurality of second probes, each corresponding to a rivet 13. For example, if the circuit breaker 10 includes six rivets 13, then the second probe group 320 includes six second probes.

[0067] The terminal detection mechanism 400 includes a second drive assembly 410 mounted on a base 100 and a third probe group 420 connected to the output terminal of the second drive assembly 410. The third probe group 420 is opposite to the side opening and electrically connected to the high-voltage contact plate 110. The second drive assembly 410 drives the third probe group 420 to make contact with multiple terminals 12. Optionally, the third probe group 420 includes multiple third probes, each corresponding to a terminal 12. For example, if the circuit breaker 10 includes four terminals 12, then the third probe group 420 includes four third probes. Optionally, the third probes can be electrically connected to the terminals 12 by plugging them in.

[0068] A handle operating mechanism 500 is mounted on the base 100 and faces the side opening, and is used to drive the handle 11 to close the circuit. By setting the handle operating mechanism 500, the circuit breaker 10 can be automatically switched from the open state to the closed state to detect the withstand voltage performance of the circuit breaker 10 under different operating conditions.

[0069] The working process of this circuit breaker withstand voltage testing device is as follows:

[0070] First, after the circuit breaker 10 to be tested is opened, it is fixed in the installation space 201, so that each plug-in port 14 of the circuit breaker 10 is electrically connected to the first probe group 230, and the wiring terminals 12 and handle 11 of the circuit breaker 10 are aligned with the side opening, and the rivets 13 on the circuit breaker 10 are aligned with the top opening.

[0071] Then, the first drive assembly 310 is controlled to drive the second probe group 320 to contact each rivet 13, and at the same time, the second drive assembly 410 is controlled to drive the third probe group 420 to contact each terminal 12.

[0072] Afterwards, the high-voltage end and the ground end of the control withstand voltage device are in contact with the high-voltage contact plate 110 and the ground contact plate 120 on the base 100, respectively. If the circuit breaker 10 is not broken down within the specified time, it indicates that the withstand voltage test of the circuit breaker 10 is qualified in the open state. If the circuit breaker 10 is broken down at a certain point, the withstand voltage device will alarm, indicating that the withstand voltage test at that point of the circuit breaker 10 is unqualified in the open state.

[0073] Afterwards, the high-voltage end and ground end of the control withstand voltage equipment are separated from the high-voltage contact plate 110 and the ground contact plate 120, and then the control handle operating mechanism 500 drives the handle 11 to close the circuit.

[0074] Finally, the high-voltage end and ground end of the withstand voltage device are brought into contact with the high-voltage contact plate 110 and the ground contact plate 120 respectively. If the circuit breaker 10 is not broken down within the specified time, it indicates that the withstand voltage test of the circuit breaker 10 is qualified in the closed state. If the circuit breaker 10 is broken down at a certain point, the withstand voltage device will alarm, indicating that the withstand voltage test at that point of the circuit breaker 10 is unqualified in the closed state.

[0075] This circuit breaker withstand voltage testing device automates the withstand voltage testing of circuit breaker 10, improving testing efficiency and worker safety compared to manual testing. Furthermore, it can simultaneously test the withstand voltage performance of the terminals 12 and rivets 13 of circuit breaker 10, offering diverse testing functions to meet various testing needs. In addition, the device has a simple structure, is easy to control, and has a low cost.

[0076] By setting a high-voltage contact plate 110 and a ground contact plate 120 on the base 100 as a bridge for the first probe group 230, the second probe group 320 and the third probe group 420 to be electrically connected to the withstand voltage equipment, the wiring of the circuit breaker withstand voltage testing device is relatively neat, and it is also relatively independent of the withstand voltage equipment, which facilitates storage and transportation.

[0077] It is worth noting that the structure and working principle of the pressure-resistant equipment are existing technologies, so they will not be described in detail here.

[0078] Optionally, the first probe group 230 can be electrically connected to the high-voltage contact plate 110 via a wire. Similarly, the second probe group 320 can be electrically connected to the ground contact plate 120 via a wire, and the third probe group 420 can be electrically connected to the high-voltage contact plate 110 via a wire.

[0079] Optionally, in one possible embodiment, the base 100 includes a plate and a plurality of legs disposed below the plate. The base 100 has a simple structure and is easy to manufacture.

[0080] Optionally, such as Figure 6 As shown, in one possible embodiment, the positioning mechanism 200 further includes a back plate 210 and multiple baffle assemblies 220. The multiple baffle assemblies 220 are evenly spaced on one side of the back plate 210, and the back plate 210 and two adjacent baffle assemblies 220 form an installation space 201. Each installation space 201 corresponds to a first probe group 230, which is mounted on the back plate 210. That is, the positioning mechanism 200 can simultaneously fix multiple circuit breakers 10. When fixing the circuit breaker 10, it can be pushed into the mounting space 201 from the side opening until it abuts against the back plate 210. Since the first probe group 230 is mounted on the back plate 210, during the pushing process, the first probe group 230 gradually contacts the power outlet 14 on the circuit breaker 10 until the circuit breaker 10 abuts against the back plate 210, at which point each first probe in the first probe group 230 is properly engaged with its corresponding power outlet 14. Using the positioning mechanism 200 to position the circuit breaker 10 improves the efficiency of picking up and placing the circuit breaker 10, thereby improving the withstand voltage testing efficiency of the circuit breaker 10.

[0081] Furthermore, each installation space 201 is also equipped with a second probe group 320 and a third probe group 420. The operating mechanism of the handle 11 is used to drive the handle 11 of the circuit breaker 10 in each installation space 201 to close. This configuration enables the circuit breaker withstand voltage testing device to simultaneously complete the withstand voltage testing of multiple circuit breakers 10, further improving the testing efficiency.

[0082] Optionally, in this embodiment, there are 7 baffle assemblies 220, and the 7 baffle assemblies 220 and the back plate 210 form 6 installation spaces 201, so that the withstand voltage test of 6 circuit breakers 10 can be completed at the same time.

[0083] Furthermore, such as Figures 6-9 As shown, the baffle assembly 220 includes a fixed baffle 221 and multiple removable baffles 222. The fixed baffle 221 is mounted on the base 100, and the multiple removable baffles 222 are stacked sequentially on the fixed baffle 221. The fixed baffle 221 and the removable baffles 222 are detachably connected, as are adjacent removable baffles 222. This configuration allows for the selection of an appropriate number of removable baffles 222 based on the height of the circuit breaker 10.

[0084] For example, such as Figure 9 As shown, for a Class 1 circuit breaker, only the fixed baffle 221 needs to be installed. Figure 2 and Figure 3 As shown, for a Class 2 circuit breaker, a fixed baffle 221 and a removable baffle 222 can be provided. For a Class 3 circuit breaker, a fixed baffle 221 and two removable baffles 222 can be provided. For a Class 4 circuit breaker, a fixed baffle 221 and three removable baffles 222 can be provided. This configuration improves the compatibility of the positioning mechanism 200 with circuit breakers 10 of different specifications, thereby improving the versatility of the circuit breaker withstand voltage testing device.

[0085] It is worth noting that the installation space 201 can accommodate circuit breakers of up to four levels, matching the first probe group 230, the second probe group 320, and the third probe group 420. Optionally, in one possible embodiment, each installation space 201 can accommodate up to four levels of circuit breakers; therefore, the first probe group 230 includes four pairs of first probes, each pair corresponding to two insertion ports 14. The second probe group 320 includes six second probes, each corresponding to one of six rivets 13. The third probe group 420 includes four third probes, each corresponding to one of four terminals 12.

[0086] It is understandable that when using a circuit breaker withstand voltage testing device that is compatible with circuit breakers of up to level 4 to perform withstand voltage testing on circuit breakers 10 of level 4 and below, some of the first probes, some of the second probes and some of the third probes are in an unused state.

[0087] Optionally, see [link to relevant documentation] Figures 7-9In one possible embodiment, a first connecting rod 223 is provided between the fixed baffle 221 and the adjacent detachable baffle 222. One end of the first connecting rod 223 is inserted into the fixed baffle 221, and the other end is inserted into the detachable baffle 222. The fixed baffle 221 and the detachable baffle 222 are connected by the first connecting rod 223, which has a simple structure and facilitates the quick installation and removal of the detachable baffle 222.

[0088] Understandably, when the circuit breaker 10 can be fixed using only the fixing baffle 221, the first connecting rod 223 can be removed from the fixing baffle 221 or retained, depending on the need.

[0089] It is understandable that a first insertion hole can be provided on the fixed baffle 221, and a second insertion hole can be provided on the detachable baffle 222. The second insertion hole is provided in correspondence with the first insertion hole, and the two ends of the first connecting rod 223 are respectively inserted into the first insertion hole and the second insertion hole.

[0090] Furthermore, multiple first connecting rods 223 can be provided to improve the connection reliability between the fixed baffle 221 and the detachable baffle 222. In this embodiment, two first connecting rods 223 are provided. In other embodiments, the number of first connecting rods 223 can also be set to other values, such as one or three, depending on actual needs, and this application does not impose specific limitations.

[0091] Optionally, in another possible embodiment, a second connecting rod (not shown in the figure) is provided between two adjacent detachable baffles 222, with both ends of the second connecting rod inserted into the two adjacent detachable baffles 222 respectively. The fixed baffle 221 and the detachable baffle 222 are connected by the second connecting rod, which has a simple structure and facilitates the quick installation and removal of the detachable baffles 222.

[0092] In this embodiment, a first connecting rod 223 is provided between the fixed baffle 221 and the adjacent detachable baffle 222. One end of the first connecting rod 223 is inserted into the fixed baffle 221, and the other end is inserted into the detachable baffle 222. Furthermore, a second connecting rod is provided between two adjacent detachable baffles 222, and both ends of the second connecting rod are respectively inserted into the two adjacent detachable baffles 222.

[0093] In this embodiment, a second insertion hole needs to be provided at both ends of the detachable baffle 222 in the height direction, and the two ends of the second connecting rod are respectively inserted into the corresponding second insertion hole.

[0094] Further, see also Figures 6-9Each installation space 201 has a base plate 224 at its bottom to support the circuit breaker 10. A stop block 225 is provided at one end of the base plate 224 near the side opening, and the stop block 225 abuts against the circuit breaker 10. By setting the base plate 224 to support the circuit breaker 10, the distance between the circuit breaker 10 and the base 100 can be determined by designing the thickness of the base plate 224, facilitating the engagement of the second probe group 320 with the terminal 12 on the circuit breaker 10. The stop block 225, in conjunction with the back plate 210, clamps and secures the circuit breaker 10, further improving the positioning effect of the positioning mechanism 200 on the circuit breaker 10.

[0095] Optionally, all baffle assemblies 220 are conductive and attached to the housing of the circuit breaker 10, and are electrically connected to the ground contact plate 120. This configuration allows the baffle assembly 220 to perform withstand voltage tests on the housing of the circuit breaker 10, further enhancing the versatility of the circuit breaker withstand voltage testing device's functions, thereby improving the quality control requirements for the circuit breaker 10 and resulting in higher quality qualified circuit breakers 10.

[0096] Alternatively, the baffle assembly 220 may be made of copper.

[0097] Alternatively, in one possible embodiment, the backplate 210 is made of an insulating material, and the first probe group 230 is electrically connected to the high-voltage contact plate 110 via wires.

[0098] Optionally, such as Figure 10 As shown, the first drive assembly 310 includes a first bracket 311, a first connector 312, a conductive plate 313, and a first drive component 314.

[0099] The first bracket 311 is disposed on the base 100. Optionally, in one possible embodiment, the first bracket 311 is located on the side of the back plate 210 opposite to the baffle assembly 220.

[0100] The first connector 312 is slidably connected to the first bracket 311 in the vertical direction. Optionally, see further. Figure 10 A slider 315 can be set on the first connector 312 and a slide rail 316 can be set on the first bracket 311. The sliding connection between the first connector 312 and the first bracket 311 is achieved through the sliding connection between the slide rail 316 and the slider 315. This configuration is simple and the sliding of the first connector 312 is smooth.

[0101] The conductive plate 313 is connected to the first connector 312, and the second probe group 320 is mounted on the conductive plate 313 and electrically connected to the conductive plate 313. The conductive plate 313 is electrically connected to the ground contact plate 120. That is, the conductive plate 313 serves as a bridge for the electrical connection between the second probe group 320 and the ground contact plate 120. This arrangement helps to reduce wiring and improves the assembly efficiency of the circuit breaker withstand voltage testing device.

[0102] The first driving element 314 is mounted on the first bracket 311. The output end of the first driving element 314 is connected to the first connecting element 312, and is used to drive the first connecting element 312 to lower the conductive plate 313 so that the second probe group 320 can make contact and electrical connection with the multiple rivets 13. It is understood that the first driving element 314 can be, but is not limited to, a cylinder.

[0103] The first drive component 310 has a simple structure and is easy to control.

[0104] Optionally, the first connector 312 may be made of insulating material to reduce the risk of short circuit.

[0105] Further, see also Figure 10 In one possible embodiment, the first connector 312 includes a connecting plate 3121 slidably connected to the first bracket 311, an extension plate 3122 connected to the connecting plate 3121, and an insulating connecting rod 3123. One end of the insulating connecting rod 3123 is connected to the extension plate 3122, and the other end is connected to the conductive plate 313. This first connector 312 has a simple structure and is stable and reliable.

[0106] Optionally, multiple insulating links 3123 may be provided to improve the connection reliability between the extension plate 3122 and the conductive plate 313.

[0107] Optionally, the output end of the first drive unit 314 is connected to the connecting plate 3121 via a floating connector.

[0108] Optionally, such as Figure 11 As shown, in one possible embodiment, the first support 311 includes a vertical plate 3111 and side plates 3112 disposed on both sides of the vertical plate 3111. This arrangement not only makes the first support 311 structurally more stable, but also makes the connection area between the first support 311 and the base 100 larger, thereby improving the connection reliability between the first support 311 and the base 100.

[0109] Further, see also Figure 10 and Figure 11The first drive assembly 310 also includes a mounting bracket 317 that is vertically height-adjustable on the first bracket 311. The mounting bracket 317 is used to mount the first drive member 314. With this configuration, when testing circuit breakers 10 of different levels, the height of the first drive member 314 can be adjusted by adjusting the height of the mounting bracket 317 to meet the testing requirements.

[0110] Optionally, the first bracket 311 is provided with an oblong hole 31111 extending vertically. Bolts pass through the mounting bracket 317 and the oblong hole 31111 and are connected to the locking member 318. When it is necessary to adjust the height of the mounting bracket 317, loosen the bolts, then manually push the mounting bracket 317 to the required height, and then tighten the bolts. The structure is simple and the adjustment is convenient.

[0111] Optionally, such as Figure 5 and Figure 12 As shown, the base 100 is provided with an elongated hole 130, which is correspondingly set with the installation space 201.

[0112] The second drive assembly 410 includes a second drive member 411, a second connector 412, and a probe mounting plate 413. The second drive member 411 is disposed at the bottom of the base 100, and its output end is connected to the second connector 412. One end of the probe mounting plate 413 is connected to the second connector 412, and the other end passes through the elongated hole 130 and faces the side opening. A third probe group 420 is mounted on the portion of the probe mounting plate 413 facing the side opening. The second drive member 411 drives the second connector 412 to move the probe mounting plate 413 along the extension direction of the elongated hole 130 towards the side opening, so that the third probe group 420 makes contact with multiple terminals 12 for electrical connection.

[0113] By cooperating with the probe mounting plate 413 and the elongated hole 130, the second driving component 411 can be arranged at the bottom of the base 100. This arrangement makes full use of the various mounting surfaces of the base 100, making the arrangement of each mechanism more regular, facilitating assembly, and reducing the risk of short circuits caused by too many structures above the base 100.

[0114] Optionally, see [link to relevant documentation] Figure 12 In this embodiment, the positioning mechanism 200 is provided with 6 installation spaces 201, therefore, there are 6 elongated holes 130, and the second connecting plate 3121 is provided with 6 probe mounting plates 413.

[0115] It is understood that the second drive element 411 may be, but is not limited to, a cylinder. Preferably, it is a cylinder with a guide rod.

[0116] Optionally, the probe mounting plate 413 is conductive so that the third probes in each of the third probe groups 420 are interconnected.

[0117] Furthermore, such as Figure 13 As shown, the handle operating mechanism 500 includes a second bracket 510, a third drive member 520, and a push head 530. The second bracket 510 is mounted on the base 100. The third drive member 520 is mounted on the second bracket 510 and corresponds to the side opening. The push head 530 is connected to the output end of the third drive member 520, which drives the push head 530 to extend and contact the handle 11, pushing the handle 11 to the closed position. This handle operating mechanism 500 can close the circuit breaker 10 by controlling the third drive member 520, facilitating operation.

[0118] Optionally, see [link to relevant documentation] Figure 13 Each side opening is equipped with two third driving components 520, which are spaced vertically apart. Each third driving component 520 has a push head 530 at its output end. Specifically, the lower push head 530 is used with a Class 1 or Class 2 circuit breaker, while the upper push head 530 is used with a Class 3 or Class 4 circuit breaker. With this configuration, when performing withstand voltage tests on circuit breakers 10 of different classes, only the corresponding third driving component 520 needs to be controlled, without changing the installation position of the third driving component 520. This simplifies the withstand voltage testing process and improves testing efficiency.

[0119] Understandably, the third drive unit 520 is optional but not limited to a cylinder.

[0120] Further, see also Figure 2 and Figure 4 The base 100 is also equipped with a first switching device 140 and a second switching device 150. The first switching device 140 controls the operation of the third driving member 520, causing the third driving member 520 to drive the push head 530 to push the handle 11 to the closed position. The second switching device 150 simultaneously controls the operation of the first driving member 314 and the second driving member 411, causing the first driving member 314 to drive the second probe group 320 to contact multiple rivets 13, and causing the second driving member 410 to drive the third probe group 420 to contact multiple terminals 12. By placing the first switching device 140 and the second switching device 150 on the base 100, it is convenient for operators to manually control the start and end of the withstand voltage test of the circuit breaker 10.
