DETAILED DESCRIPTION

[0037] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the preferred embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0041] The switch cabinet circuit breaker trolley is an important device for controlling the switch state of the circuit breaker in the power system. The switch cabinet circuit breaker trolley is installed in the switch cabinet, and the opening, closing and testing of the circuit breaker are realized by manual operation to ensure the safe operation of the power system. In order to ensure the safety and reliability of the switch cabinet circuit breaker trolley, the switch cabinet circuit breaker trolley needs to be regularly tested for loop resistance, AC withstand voltage, circuit breaker characteristic test and other test items.

[0042] In the prior art, plum blossom contacts are also used in the switch cabinet circuit breaker trolley. Before testing, the test lines of the measuring equipment are clamped on the corresponding plum blossom contacts by the clamp, and then the test is carried out. However, the clamp clamped on the plum blossom contact is not fixed firmly and is easy to loosen and fall off, and the contact surface between the clamp and the plum blossom contact is small, which is easy to cause poor contact and affect the measurement accuracy.

[0043] Therefore, the switch cabinet circuit breaker trolley test auxiliary tool provided in the present application is used to connect two test lines of a measuring device to two plum blossom contacts of a switch cabinet circuit breaker trolley. Two conductive parts are provided, and an adjusting assembly is connected between the two conductive parts. The distance between the two conductive parts is adjusted by the adjusting assembly, so that the conductive parts are arranged one by one corresponding to the plum blossom contacts. A connector is connected to the conductive part, and the end of the connector facing the plum blossom contact has a plurality of plug-in plates arranged in a ring array. The plug-in plates have gaps between them. When the plug-in plates are inserted into the plum blossom contacts, the gaps are tightened to enable the connector to be clamped with the corresponding plum blossom contact. Then, the test lines are connected one by one to the conductive parts to connect the test lines to the corresponding plum blossom contacts. In this way, the test auxiliary tool is in close contact and connection with the plum blossom contacts, and is not easy to loosen and fall off, effectively avoiding the problem of poor contact affecting the measurement accuracy.

[0044] The present application will be described in detail below in conjunction with the drawings and specific embodiments.

[0045] Figure 1 The structure schematic diagram of the switch cabinet circuit breaker trolley test auxiliary tool provided in the present application is shown in the following figure; Figure 2 The structure schematic diagram of the switch cabinet circuit breaker trolley test auxiliary tool provided in the present application is shown in the following figure; Figure 1 The structure schematic diagram of the switch cabinet circuit breaker trolley test auxiliary tool provided in the present application is shown in the following figure; Figure 3 The structure schematic diagram of the switch cabinet circuit breaker trolley test auxiliary tool provided in the present application is shown in the following figure; Figure 1Structure diagram of the middle electrically conductive member; Figure 4 For Figure 1 Structure diagram of the middle joint.

[0046] Referring to Figures 1 to 4 The application provides a switch cabinet circuit breaker trolley test auxiliary tool, which is used for connecting two test lines of a measuring device to two wrench contacts of a switch cabinet circuit breaker trolley, and includes an adjusting assembly 100 and two electrically conductive members 200. The two electrically conductive members 200 are connected to two ends of the adjusting assembly 100, respectively. The adjusting assembly 100 is used for adjusting the distance between the two electrically conductive members 200, so that the distance between the two electrically conductive members 200 matches the distance between the two wrench contacts, and the electrically conductive members 200 are arranged in one-to-one correspondence with the wrench contacts. The electrically conductive member 200 is connected with a joint 300. The joint 300 has a plurality of plug-in plates 310 at one end facing the wrench contacts. The plug-in plates 310 are arranged in a ring array. The plug-in plates 310 have gaps 311 between them. The plug-in plates 310 are used for being inserted into the corresponding wrench contacts. When the plug-in plates 310 are inserted into the wrench contacts, the gaps 311 are tightened, so that the joint 300 is clamped with the corresponding wrench contact. The electrically conductive member 200 is connected with the test line in one-to-one correspondence, so that the test line is connected with the corresponding wrench contact.

[0047] In some embodiments, the switch cabinet circuit breaker trolley usually has a plurality of wrench contacts. In order to ensure the safety and reliability of the switch cabinet circuit breaker trolley, two test lines of a measuring device need to be connected to two wrench contacts for testing, such as testing two wrench contacts in the same column, testing two wrench contacts arranged in the same row or at intervals. The distance between the wrench contacts in different positions is different, and the distance between the wrench contacts on the switch cabinet circuit breaker trolleys of different specifications is also different. Therefore, by arranging the adjusting assembly 100 between the two electrically conductive members 200, the adjusting assembly 100 can flexibly adjust the distance between the two electrically conductive members 200 according to the different distances between the two wrench contacts, improving the versatility and practicality of the test auxiliary tool. Further, the adjusting process of the adjusting assembly 100 is simple and intuitive. The staff can quickly adjust the distance between the two electrically conductive members 200 through simple operation, simplifying the preparation work before testing. By quickly adjusting the distance between the electrically conductive members 200, the time wasted due to the mismatch of the distance before testing is reduced, thereby improving the work efficiency.

[0048] It should be noted that in order to make the test auxiliary tool closely connected with the plug contact, the electrically conductive part 200 is connected with a connector 300, the connector 300 has a plurality of insertion plates 310 at one end towards the plug contact, each insertion plate 310 is arranged in a ring array, and the shape matches the inner cavity of the plug contact. And each insertion plate 310 has a gap 311, in the specific implementation, the outer diameter surrounded by each insertion plate 310 is slightly larger than the diameter of the inner cavity of the plug contact. Thus, when each insertion plate 310 is inserted into the corresponding plug contact, each gap 311 becomes smaller, and the outer wall of each insertion plate 310 closely fits the inner cavity of the plug contact to ensure the stable connection of the connector 300 and the plug contact. Such design effectively avoids the test auxiliary tool from loosening and falling off during the test. And the outer wall of each insertion plate 310 closely fits the inner cavity of the plug contact, preventing errors caused by poor contact during the test, solving the problem of small contact surface between the clamp and the plug contact in the prior art, which easily causes poor contact and affects the measurement accuracy.

[0049] In actual use, the electrically conductive part 200 can be connected with different specifications of the connector 300, so that the test auxiliary tool can adapt to different specifications of the plug contact, thereby improving the versatility and practicality. That is, the number of insertion plates 310 can be set according to actual needs to form different specifications of the connector 300.

[0050] In this application, the electrically conductive part 200 is connected one-to-one with the test line, and the electrically conductive part 200 can be made of high-conductivity material to ensure stable transmission of current during the test. Thus, the plug contact is connected one-to-one with the test line, and the test auxiliary tool provides stable connection support during the test to ensure the accuracy and reliability of the test results.

[0051] In actual use, first, according to the actual distance between the two plug contacts of the switch cabinet circuit breaker trolley, adjust the adjusting assembly 100 to adjust the distance between the two electrically conductive parts 200, and ensure that the distance between the two electrically conductive parts 200 matches the distance of the plug contact. Then, align the connector 300 on the electrically conductive part 200 with the plug contact, and insert each insertion plate 310 into the corresponding plug contact. With the insertion of the insertion plate 310, the gap 311 will gradually tighten, so that the connector 300 and the plug contact form a stable clamping structure. Then, connect the test line one-to-one with the electrically conductive part 200, and start the measuring device after confirming that all connections are stable and reliable to start the test of the switch cabinet circuit breaker trolley. Thus, using the switch cabinet circuit breaker trolley test auxiliary tool provided by the application can conveniently and quickly complete the connection and test operation of the test line, thereby improving the test efficiency and safety.

[0052] Referring to Figure 2In the embodiment of the present application, the conductive part 200 is provided with at least one wiring part 210, and the wiring part 210 is used to connect with the corresponding test line.

[0053] In some embodiments, the wiring part 210 is arranged to make the connection process of the test line more intuitive and convenient. The staff can quickly identify and connect the corresponding test line without searching for the appropriate connection point on the conductive part 200, thereby improving work efficiency.

[0054] The wiring part 210 can be a wiring column to wrap the connection end of the test line on the wiring column, or the wiring part 210 can be other structures that can be stably connected with the connection line, which is not limited in the embodiment. Thus, the problem of poor contact caused by improper or loose connection is avoided, and the stable transmission of current during the test process is ensured.

[0055] It can be understood that one wiring part 210 can be arranged on the conductive part 200, or the wiring part 210 can be arranged at different positions of the conductive part 200, which can be arranged according to actual needs, and the embodiment is not limited herein.

[0056] Referring to Figure 2 In the embodiment of the present application, the connector 300 and the wiring part 210 are located on opposite sides of the conductive part 200.

[0057] It should be noted that the connector 300 and the wiring part 210 are arranged on different sides of the conductive part 200, which makes the connection of the test line and the wiring part 210 more simple and convenient, and avoids mutual interference or damage caused by misoperation during the test process. That is, if the connector 300 and the wiring part 210 are arranged on the same side of the conductive part 200, when the connector 300 is inserted into the torx contact, the connection of the test line and the wiring part 210 is more difficult due to the small gap between the conductive part 200 and the torx contact, which is not convenient to operate.

[0058] Referring to Figure 3 and Figure 4 In the embodiment of the present application, the conductive part 200 is provided with a first connecting part 220, and the end of the connector 300 away from the torx contact is provided with a second connecting part 320, and the first connecting part 220 and the second connecting part 320 are detachably connected.

[0059] In the present application, the detachable design of the first connecting part 220 and the second connecting part 320 makes the disassembly and installation of the connector 300 more convenient.

[0060] Further, since the joint 300 is detachably connected with the conductive member 200, when the joint 300 needs to be replaced or repaired, only the first connecting part 220 and the second connecting part 320 need to be detached, without the need to replace the entire conductive member 200. Not only the cost is reduced, but also the maintainability of the equipment is improved. Thus, the safety hazards caused by aging, damage or poor contact of the joint 300 are avoided.

[0061] In actual use, in order to adapt to different specifications of the star-shaped contact, the plug-in plates 310 at the end of the joint 300 facing the star-shaped contact can be set differently according to different specifications of the star-shaped contact, so that the outer diameter surrounded by the plug-in plates 310 is slightly larger than the diameter of the inner cavity of the corresponding star-shaped contact, thereby ensuring that when the plug-in plates 310 are inserted into the corresponding star-shaped contact, the gaps 311 are tightened. Different specifications of the joint 300 are designed, and the second connecting part 320 can be set to be the same. In this way, the first connecting part 220 does not need to be changed, and the conductive member 200 does not need to be replaced.

[0062] It should be noted that the first connecting part 220 can be a threaded rod, the second connecting part 320 can be provided with an inner threaded hole matched with the threaded rod, and the first connecting part 220 and the second connecting part 320 are threadedly connected. Alternatively, the second connecting part 320 can be provided with a spring clamping mechanism slot, and the first connecting part 220 can be a plug rod matched with the slot. The first connecting part 220 and the second connecting part 320 are connected together by the clamping force of the spring. The specific structure of the first connecting part 220 and the second connecting part 320 can be set according to actual needs, which is not limited in the embodiment.

[0063] Referring to Figure 1 and Figure 2 In the embodiment, the adjusting assembly 100 includes a first adjusting part 110 and a second adjusting part 120 slidably connected with the first adjusting part 110, and two conductive members 200 are respectively connected with the first adjusting part 110 and the second adjusting part 120. When the first adjusting part 110 and the second adjusting part 120 move towards each other or move in opposite directions, the two conductive members 200 move closer to or away from each other.

[0064] The sliding connection between the first adjusting part 110 and the second adjusting part 120 allows the distance between the two conductive members 200 to be flexibly adjusted. The design of the sliding connection makes the adjustment of the distance more accurate. By finely controlling the relative positions of the first adjusting part 110 and the second adjusting part 120, the distance between the two conductive members 200 can be accurately controlled to adapt to the distance between the two star-shaped contacts.

[0065] Meanwhile, the design of the adjusting assembly 100 enables the staff to adjust the distance between the two conductive members 200 without using tools or performing complicated operations, thereby improving work efficiency and reducing operation difficulty. In this way, by precisely controlling the distance between the two conductive members 200, the joint 300 can be ensured to be aligned with the corresponding star contact, accurately inserted into the corresponding star contact, and in good contact with the star contact during the test, thereby avoiding test errors caused by poor contact and improving the accuracy and reliability of the test.

[0066] It should be noted that the first adjusting member 110 can be a hollow rod-shaped structure, and the second adjusting member 120 can be a rod-shaped structure matched with the cavity of the first adjusting member 110, so that the second adjusting member 120 is inserted into the first adjusting member 110 and can slide with the first adjusting member 110.

[0067] Referring to Figure 1 and Figure 2 In the embodiment of the present application, the two conductive members 200 are each provided with a third connecting part 230, and the first adjusting member 110 and the second adjusting member 120 are each provided with a fourth connecting part 130, and the third connecting part 230 and the fourth connecting part 130 are one-to-one detachably connected to enable the two conductive members 200 to be connected with the first adjusting member 110 and the second adjusting member 120, respectively.

[0068] In specific implementation, the third connecting part 230 and the fourth connecting part 130 are one-to-one detachably connected, so that the staff can quickly replace or adjust the conductive member 200 according to actual needs. Meanwhile, when the conductive member 200 or the adjusting assembly 100 fails, the staff can replace the faulty part alone, thereby reducing the maintenance cost and time cost.

[0069] It should be noted that the fourth connecting part 130 can be a screw rod-shaped structure with external threads, and the third connecting part 230 can be provided with an internal thread part matched with the screw rod, and the third connecting part 230 and the fourth connecting part 130 are threadedly connected. Alternatively, the third connecting part 230 can be provided as a slot with a spring clamping mechanism, and the fourth connecting part 130 can be a plug rod-shaped structure matched with the slot, and the third connecting part 230 and the fourth connecting part 130 are connected together by the clamping force of the spring. The specific structure of the third connecting part 230 and the fourth connecting part 130 can be set according to actual needs, which is not limited in the embodiment.

[0070] Referring to Figure 1 and Figure 2In the embodiment of the present application, the first adjusting member 110 is provided with a knob 140, which is configured to move relative to the first adjusting member 110 to switch between a locked position and an unlocked position; in the locked position, the knob 140 abuts against the second adjusting member 120 to fix the second adjusting member 120 to the current position; in the unlocked position, the knob 140 is disengaged from the second adjusting member 120, and the first adjusting member 110 and the second adjusting member 120 move towards each other or move in the opposite direction to adjust the spacing between the conductive members 200.

[0071] It can be understood that the knob 140 is provided to make the operation of adjusting the spacing between the conductive members 200 more convenient. The staff only needs to rotate the knob 140 to switch between the locked position and the unlocked position, without the need to use additional tools or perform complex operations, thereby reducing the operation difficulty and improving the work efficiency.

[0072] In specific implementation, when the knob 140 is in the locked position, the knob 140 penetrates through the first adjusting member 110 and abuts against the second adjusting member 120, thereby fixing the second adjusting member 120 to the current position. This ensures that the spacing between the conductive members 200 will not be accidentally changed when it needs to be fixed, thereby enhancing the stability of the device. Meanwhile, when the spacing needs to be adjusted, the staff only needs to rotate the knob 140 to the unlocked position to disengage the knob 140 from the second adjusting member 120, and then the adjustment operation can be performed.

[0073] Referring to Figure 1 and Figure 2 In the embodiment of the present application, the knob 140 has a threaded portion 141, and the first adjusting member 110 is provided with a threaded hole 111 matched with the threaded portion 141, and the knob 140 is threadedly connected with the first adjusting member 110 through the threaded hole 111.

[0074] In specific implementation, the knob 140 and the first adjusting member 110 are threadedly connected, when the knob 140 is rotated to the locked position, the knob 140 penetrates through the threaded hole 111 and abuts against the second adjusting member 120, and the close combination of the threaded portion 141 and the threaded hole 111 effectively prevents the knob 140 from loosening or moving when subjected to external force, thereby ensuring that the second adjusting member 120 is stably fixed to the current position, so that the positions of the first adjusting member 110 and the second adjusting member 120 are relatively fixed.

[0075] When the relative positions of the first adjusting member 110 and the second adjusting member 120 need to be adjusted, that is, the spacing between the two conductive members 200 needs to be adjusted, the staff reversely rotates the knob 140 to move the threaded portion 141 relative to the threaded hole 111 in the opposite direction, so that the knob 140 is disengaged from the second adjusting member 120.

[0076] Referring toFigure 1 And Figure 2 In the embodiment of the present application, the knob 140 is provided with a holding portion 142, which is used to drive the threaded portion 141 to rotate relative to the threaded hole 111, so as to move the knob 140 relative to the first adjusting piece 110.

[0077] It can be understood that the provision of the holding portion 142 enables the worker to conveniently hold the knob 140, thereby easily performing the rotation operation. The convenience of operation is improved, the difficulty of operation is reduced, and the switching of the position of the knob 140 is more efficient. Thus, in the use process, the worker drives the threaded portion 141 to rotate relative to the threaded hole 111 through the holding portion 142, so as to make the knob 140 abut against or away from the second adjusting piece 120, so as to lock the position and switch between the locked positions.

[0078] In the embodiment of the present application, the first adjusting piece 110 and the second adjusting piece 120 are both insulating pieces.

[0079] It should be noted that the insulating piece can provide electrical isolation to prevent accidental conduction of current or voltage. Designing the first adjusting piece 110 and the second adjusting piece 120 as insulating pieces can ensure that no current or voltage is conducted through the first adjusting piece 110 and the second adjusting piece 120 during the test, thereby avoiding affecting the test of the switch cabinet circuit breaker trolley.

[0080] In summary, the switch cabinet circuit breaker trolley test auxiliary tool provided by the present application is used to connect two test lines of a measuring device to two star-shaped contacts of a switch cabinet circuit breaker trolley. By providing two conductive pieces, the two conductive pieces are connected by an adjusting assembly, and the distance between the conductive pieces is adjusted by the adjusting assembly, so that the conductive pieces are arranged one by one corresponding to the star-shaped contacts. By connecting the connector to the conductive piece, the end of the connector facing the star-shaped contact has a plurality of plug-in boards arranged in a ring array, and each plug-in board has a gap. When each plug-in board is inserted into the star-shaped contact, each gap is tightened, so that the connector is clamped with the corresponding star-shaped contact. Then, the test line is connected one by one to the conductive piece, so that the test line is connected to the corresponding star-shaped contact. Thus, the test auxiliary tool is in close contact and connection with the star-shaped contact, and is not easy to loosen and fall off, effectively avoiding the problem of affecting the measurement accuracy due to poor contact.
