As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0046] In the related art, the electrical test scheme of the high-voltage bus plug-in board adopts a bolt locking mode, which requires multiple people to assist in performing test procedures and assembly procedures, and the assembly procedure is complicated. After the test is completed, it also needs to be disassembled, which is time-consuming and laborious, and has high labor cost and low test efficiency.

[0047] As shown in FIG. 1, Figure 2 and Figure 3 To solve the above technical problems, the electrical test tool provided by the embodiments of the present application includes at least one test assembly 10, the test assembly 10 includes a support 400, a conductive part 500, an elastic part 800, a pressing part 700 and a driving part 100, the conductive part 500 is arranged on the support 400, the conductive part 500 has a positioning groove 510 for accommodating the joint 310 at the bottom of the high-voltage bus plug-in board 300 to be tested; wherein the support 400 is insulated, and the maximum voltage value that the support 400 can withstand is not less than the test voltage value of the high-voltage bus plug-in board 300; the elastic part 800 is insulated, and the elastic part 800 abuts against the end face of the top of the high-voltage bus plug-in board 300 and / or is arranged in the groove at the top of the high-voltage bus plug-in board 300; the maximum voltage value that the elastic part 800 can withstand is not less than the test voltage value of the high-voltage bus plug-in board 300; the pressing part 700 and the driving part 100 are connected, the elastic part 800 and the high-voltage bus plug-in board 300 are located between the conductive part 500 and the pressing part 700, and the driving part 100 is used to drive the pressing part 700 to move close to or away from the conductive part 500, so that the pressing part 700 can press the elastic part away from one end of the high-voltage bus plug-in board 300.

[0048] In these embodiments, the present application aims to improve the electrical test process of the high-voltage bus plug-in board 300 with a new electrical test tool. The core goal of this design is to improve test efficiency by reducing manual intervention and simplifying the installation and disassembly process of the test equipment.

[0049] The support member 400 is made of insulating material and can withstand a maximum voltage of not less than the test voltage value, ensuring electrical safety during testing. For example, the support member 400 can withstand a maximum voltage of 95KV. Of course, in other embodiments, the support member 400 can withstand a maximum voltage of 85KV, 90KV, 100KV, 105KV, or 110KV, etc. The conductive member 500 is installed on the support member 400 and is provided with a positioning groove 510 to stably place the bottom joint 310 of the high-voltage bus plug-in board 300, ensuring the stability and reliability of the contact during testing.

[0050] The elastic member 800 is also made of insulating material and can withstand a maximum voltage of not less than the test voltage value. For example, the elastic member 800 can withstand a maximum voltage of 95KV. Of course, in other embodiments, the elastic member 800 can withstand a maximum voltage of 85KV, 90KV, 100KV, 105KV, or 110KV, etc. The elastic member 800 is designed to abut against the top end face of the high-voltage bus plug-in board 300 or penetrate into the recess at the top of the high-voltage bus plug-in board 300, using its elastic properties to maintain good contact with the high-voltage bus plug-in board 300 while preventing current leakage.

[0051] The extrusion member 700 and the driving member 100 work together to move the extrusion member 700 towards the conductive member 500 through the operation of the driving member 100, thereby firmly fixing the high-voltage bus plug-in board 300 in the test position. This mechanism allows quick installation and disassembly of the high-voltage bus plug-in board 300, greatly improving test efficiency.

[0052] For example, the high-voltage bus plug-in board 300 has a center line, the top and bottom of the high-voltage bus plug-in board 300 are located on the center line, and the driving member 100 is used to drive the extrusion member 700 to move on the center line, achieving the extrusion member 700 approaching or moving away from the high-voltage bus plug-in board 300.

[0053] Obviously, only need to put the joint 310 of the high-voltage bus patch panel 300 into the positioning groove 510, and then use the driving member 100 to control the extrusion member 700 to approach the high-voltage bus patch panel 300 until the matched conductive member 500 clamps the high-voltage bus patch panel 300, and then by connecting the test power supply at the bottom of the high-voltage bus patch panel 300 and connecting the zero line at the top of the high-voltage bus patch panel 300, the test can be carried out. After the test is completed, the extrusion member 700 is driven away from the high-voltage bus patch panel 300 to release the high-voltage bus patch panel 300, through the automatic or semi-automatic fixing and releasing mechanism, the demand for labor is reduced, and the labor cost is reduced. And, the installation and disassembly of the high-voltage bus patch panel 300 are more convenient and fast, and the preparation and ending test time is saved. Through the above characteristics, the overall test process is optimized, and the test speed and accuracy are improved. Among them, all high-voltage related components in direct contact with both ends of the high-voltage bus patch panel 300 are made of insulating materials, which effectively ensures the safety during the test.

[0054] As shown in Figure 2 , in some embodiments, the number of test assemblies 10 is multiple, and the conductive members 500 of the multiple test assemblies 10 are connected in series.

[0055] In these embodiments, the number of test assemblies 10 is set to multiple, which can perform electrical tests on multiple high-voltage bus patch panels 300, further improving the detection efficiency.

[0056] For example, in this embodiment, the number of test assemblies 10 is 3. Of course, in other embodiments, the number of test assemblies 10 can also be 1, 2, 4, 5, 6, or 7, etc.

[0057] Among them, by connecting the conductive members 500 of the multiple test assemblies 10 in series, the circuit layout can be reduced, and only one of the conductive members 500 needs to be connected to the test circuit to realize that all the conductive members 500 are connected to the test circuit. It should be noted that the multiple test assemblies 10 are in parallel connection, that is, the test voltage of each test assembly 10 is equal.

[0058] Here, the test circuit will not be described again, and the test circuit only provides a test voltage, as long as it can be equivalent.

[0059] As shown in Figure 2 and Figure 4 , in some embodiments, the electrical test tool further comprises a conductive plate 600, one end of the conductive plate 600 is connected with the support 400 of all test assemblies 10, the other end of the conductive plate 600 is connected with the conductive member 500 of all test assemblies 10, and the conductive plate 600 and the conductive member 500 abut.

[0060] In these embodiments, the electrical test fixture adds a conductive plate 600, which further optimizes the efficiency and reliability of the parallel operation of multiple test assemblies 10.

[0061] As a common connection point for all test assemblies 10, the conductive plate 600 can simplify the power supply access, and only one power supply interface can supply power to multiple test assemblies 10 at the same time, improving the efficiency of power management.

[0062] Moreover, by directly abutting the conductive plate 600 with the conductive parts 500 of all test assemblies 10, especially, both the conductive parts 500 and the conductive plate 600 are in surface contact, it can ensure that each test assembly 10 has a stable current supply, avoiding test errors or failures caused by poor connection.

[0063] Furthermore, as an intermediate medium, the conductive plate 600 ensures that all test assemblies 10 work under the same conditions, thereby improving the consistency and comparability of test results.

[0064] In addition, if a test assembly 10 needs to be replaced or repaired, it only needs to disconnect the assembly from the conductive plate 600, without affecting the normal operation of other test assemblies 10.

[0065] It should be noted that one end of the conductive plate 600 needs to be connected with the support parts 400 of all test assemblies 10. The support parts 400 are usually insulating, so the connection point should be designed to ensure good electrical isolation to prevent current leakage through the support parts 400. The other end of the conductive plate 600 needs to be connected with the conductive parts 500 of all test assemblies 10. In order to ensure reliable electrical contact, spring contacts, threaded connections or other forms of mechanical connections can be used.

[0066] For example, the conductive plate 600 should be made of materials with good electrical conductivity and corrosion resistance, such as copper or copper alloy. In addition, the design of the conductive plate 600 should take into account the heat dissipation problem to prevent overheating when a large current passes for a long time. Alternatively, except for the parts connected with the conductive parts 500 and the support parts 400, the rest of the conductive plate 600 should be insulated to prevent accidental electric shock or short circuit accidents.

[0067] Of course, in this application, since the conductive plate 600, the support parts 400 and the part of the top of the high-voltage bus plug-in board 300 beyond the end face need to be immersed in insulating oil, the conductive plate 600 can also not be provided with an insulating layer.

[0068] As shown in Figure 2 In some embodiments, the elastic part 800 is an insulating elastic sleeve, and a reinforcing rib is arranged in the insulating elastic sleeve. The reinforcing rib extends along the circumference of the insulating elastic sleeve and is located at one end of the insulating elastic sleeve close to the extruding part 700.

[0069] In these embodiments, the insulating elastic sleeve ensures that during high-voltage testing, current does not leak through the elastic member 800, enabling isolation of high and low voltage electric fields, avoiding product injury and breakdown scrap, and improving the safety of testing.

[0070] The insulating elastic sleeve has good elastic recovery ability and can maintain its shape and function after multiple compression and release, ensuring the stability and consistency of the test. Moreover, since the insulating elastic sleeve is a hollow structure, it is beneficial to deformation and reduces the extrusion damage to the inner wall of the groove on the top of the high-voltage bus patch panel 300.

[0071] It should be noted that the groove inner wall on the top of the high-voltage bus patch panel 300 and the insulating elastic sleeve are in sealed contact to prevent external insulating oil from entering. By controlling the liquid level of the insulating oil, the liquid level of the insulating oil can be slightly lower than the end face of the top of the high-voltage bus patch panel 300, which can prevent the insulating oil from contacting the insulating elastic sleeve and reduce the damage of the insulating oil to the insulating elastic sleeve.

[0072] For example, the insulating elastic sleeve is a silicone sleeve. Of course, in other embodiments, the insulating elastic sleeve can also be an EPDM (ethylene propylene rubber) sleeve.

[0073] Furthermore, the reinforcing ribs are arranged along the circumference of the insulating elastic sleeve, increasing the structural strength of the sleeve and preventing deformation or damage under high pressure and repeated compression. The reinforcing ribs are located at one end of the insulating elastic sleeve close to the extrusion member 700, which helps to evenly distribute the pressure during extrusion and prevent deformation or damage caused by excessive local stress. By increasing the structural strength and evenly distributing the pressure, the reinforcing ribs can significantly prolong the service life of the insulating elastic sleeve, reduce the replacement frequency, and reduce the maintenance cost.

[0074] For example, the reinforcing ribs and the insulating elastic sleeve are integrally arranged. Of course, in other embodiments, the two can also be arranged as adhesion and fixation.

[0075] As shown in Figure 2 and Figure 7 In some embodiments, the extrusion member 700 has opposite ends, one end is a connecting end, and the other end is an extrusion end. The extrusion end has an extrusion end face for abutting against the end face of the top end of the elastic member 800 away from the high-voltage bus patch panel 300. The extrusion end face has an air vent 710, which is located within the contact range of the extrusion end face and the end face of the top end of the high-voltage bus patch panel 300, and the air vent 710 is connected to a gas.

[0076] In these embodiments, the connecting end is connected to the driving member 100, and through the action of the driving member 100, the extruding member 700 can be made to approach or move away from the conductive member 500. The extruding end has an extruding end face, which directly contacts the elastic member 800, for applying pressure and ensuring the stable fixation of the high-voltage bus patch panel 300. The vent 710 is located within the contact range of the extruding end face and the end face of the elastic member 800, so that the gas can be ensured to directly act on the contact area, so that the vacuum adsorption or adhesion formed between the extruding end face and the elastic member 800 is eliminated, and the elastic member 800, the high-voltage bus patch panel 300 and the extruding member 700 are facilitated to be separated. The gas introduced through the vent 710 can play multiple roles, such as air, nitrogen, carbon dioxide, etc., including but not limited to cooling, cleaning and providing certain pressure.

[0077] Obviously, a gas supply system needs to be equipped, including a gas source, a pipeline, a valve and a flow control device, to ensure the stable supply and accurate control of the gas.

[0078] Of course, in other embodiments, the vent 710 can also be directly arranged to communicate with the outside.

[0079] As shown in Figure 1 and Figure 7 , in some embodiments, the driving member 100 includes a pneumatic cylinder, and the pneumatic cylinder has a rodless cavity exhaust hole, which is arranged in communication with the vent 710.

[0080] In these embodiments, the driving member 100 adopts a pneumatic cylinder, and the rodless cavity exhaust hole of the pneumatic cylinder is arranged in communication with the vent 710 on the extruding member 700. The pneumatic cylinder as the driving member 100 drives the extruding member 700 to approach or move away from the conductive member 500 through pneumatic drive, so as to realize the fixation and release of the high-voltage bus patch panel 300. Generally, the rodless cavity exhaust hole is located in the rodless cavity part of the pneumatic cylinder, for exhausting the gas in the rodless cavity, that is, during the retraction of the telescopic rod, the gas is exhausted from the rodless cavity exhaust hole. In other words, during the approach of the extruding member 700 to the conductive member 500, the gas in the rodless cavity is compressed and exhausted through the exhaust hole, so that the gas acts on the contact range between the extruding end face and the top end face of the high-voltage bus patch panel 300 through the vent 710.

[0081] Exemplarily, the rodless cavity exhaust hole is in communication with the vent 710 on the extruding member 700 through a pipeline or other connection mode. When the pneumatic cylinder drives the extruding member 700 to approach the conductive member 500, the gas in the rodless cavity is compressed and exhausted through the exhaust hole, enters the vent 710, and finally acts on the contact area.

[0082] As shown in Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, the electrical test tool further comprises a test frame 200, the test frame 200 has an adjusting direction, the adjusting direction is parallel to the moving direction of the extrusion piece 700, the test frame 200 comprises a bottom plate 240, a top plate 210 and a lifting adjusting piece, the bottom plate 240 is connected with the top plate 210 through the lifting adjusting piece, the lifting adjusting piece is used for adjusting the distance between the bottom plate 240 and the top plate 210 in the adjusting direction; wherein, in all test assemblies 10, the driving piece 100 is arranged on the top plate 210, and the supporting piece 400 is arranged on the bottom plate 240.

[0083] In these embodiments, the adjusting direction of the test frame 200 is parallel to the moving direction of the extrusion piece 700, which means that the height adjustment of the test frame 200 will not affect the horizontal position of the extrusion piece 700, ensuring that different sizes of high-voltage bus distribution boards 300 can be adapted, and the equipment versatility is better.

[0084] The bottom plate 240 is used to fix the supporting piece 400, the supporting piece 400 is provided with the conductive piece 500 and the elastic piece 800, which are used to fix and test the high-voltage bus distribution board 300. The top plate 210 is used to fix the driving piece 100, the driving piece 100 is connected with the extrusion piece 700 through the connecting piece to control the movement of the extrusion piece 700. The lifting adjusting piece connects the bottom plate 240 and the top plate 210, and is used to adjust the distance between the bottom plate 240 and the top plate 210 according to the height size of the high-voltage bus distribution board 300, so as to adjust the size of the whole test assembly 10 and the current high-voltage bus distribution board 300. Obviously, through the lifting adjusting piece, the distance between the bottom plate 240 and the top plate 210 can be flexibly adjusted to adapt to high-voltage bus distribution boards 300 of different heights, ensuring that the test assembly 10 can match high-voltage bus distribution boards 300 of different sizes.

[0085] Since the lifting adjusting piece can quickly adjust the height of the test assembly 10, it is not necessary to disassemble and reinstall the assembly, saving time and labor. Moreover, the adjusting process is simple and intuitive, and the operator can easily adjust the height, improving the work efficiency.

[0086] Exemplarily, the lifting adjusting piece can adopt different types such as screw jacks, hydraulic cylinders or pneumatic cylinders, and the appropriate adjusting mode can be selected according to the actual demand. Among them, the lifting adjusting piece should have high adjusting precision to ensure that the distance between the bottom plate 240 and the top plate 210 can be accurately controlled to meet different test requirements.

[0087] Exemplarily, the bottom plate 240 is connected with the lifting adjusting piece through bolts or other fixing modes to ensure firm and reliable connection. The top plate 210 is also connected with the lifting adjusting piece through bolts or other fixing modes to ensure the stability of the whole system.

[0088] As Figure 1 and Figure 2As shown, in some embodiments, the lifting adjustment component includes a screw 220 and at least two nuts. One end of the screw 220 is connected to the base plate 240, and the other end passes through a through hole in the top plate 210. At least two nuts are threadedly connected to the screw 220, and the top plate 210 is clamped between two adjacent nuts.

[0089] In these embodiments, one end of the screw 220 is connected to the base plate 240, and the other end passes through a through hole in the top plate 210. The top plate 210 is clamped between two adjacent nuts. One nut is fixed above the top plate 210, and the other nut is fixed below the top plate 210. By adjusting the position of the nuts on the screw 220, precise adjustment of the height between the base plate 240 and the top plate 210 can be achieved, suitable for high-voltage busbar sockets 300 of different heights. The combination of the screw 220 and the nuts provides fine-tuning capability, allowing for more precise height adjustment of the test assembly 10.

[0090] For example, the nut can be designed as a self-locking nut or equipped with an anti-loosening washer to prevent the nut from loosening during testing. Of course, a limit device can also be set to prevent damage or safety hazards caused by excessive rotation of the screw 220.

[0091] like Figure 1 and Figure 2 As shown, in some embodiments, the lifting adjustment component further includes an isolation tube 230, which is sleeved on the screw 220 and located between the bottom plate 240 and the top plate 210; wherein, at least a portion of the screw 220 near the high-voltage busbar connector 300 is located inside the isolation tube 230.

[0092] In these embodiments, the lifting adjustment component also includes an isolation tube 230, which is sleeved on the screw 220 and located between the base plate 240 and the top plate 210. Specifically, the portion of the screw 220 near the high-voltage busbar connector 300 is located within the isolation tube 230. This design further enhances the safety and reliability of the electrical testing fixture. The isolation tube 230 is typically made of insulating material, such as plastic or ceramic, which prevents high-voltage discharge between the threaded tip of the screw 220 and the high-voltage busbar connector 300, ensuring electrical safety and testing accuracy during the testing process. In other words, the isolation tube 230 prevents leakage accidents between the screw 220 and the high-voltage busbar connector 300.

[0093] For example, the isolation tube 230 should be made of a material with good insulation properties, such as polytetrafluoroethylene (PTFE), polycarbonate (PC) or nylon.

[0094] For example, the upper end of the isolation tube 230 is higher than the top of the high-voltage busbar connector 300 to ensure effective insulation protection throughout the entire height adjustment range.

[0095] As Figure 2 and Figure 3 shown, in some embodiments, the positioning groove 510 and the joint 310 of the high-voltage bus patch panel 300 are positioned and matched, so that the high-voltage bus patch panel 300 is in a preset position, and the corner of the positioning groove 510 is provided with a corner cleaning groove 520.

[0096] In these embodiments, the positioning groove 510 on the conductive part 500 and the joint 310 of the high-voltage bus patch panel 300 are positioned and matched, which ensures that the high-voltage bus patch panel 300 is in a preset position.

[0097] For example, in this application, the cross section of the joint 310 is square, and the cross section of the positioning groove 510 is also square. The size and shape of the positioning groove 510 need to be accurately processed to ensure that the high-voltage bus patch panel 300 can be accurately inserted and fixed in the predetermined position, avoiding test errors caused by position deviation. Of course, in other embodiments, the cross section of the joint 310 is elliptical, and the cross section of the positioning groove 510 is also elliptical. Alternatively, the cross section of the joint 310 is triangular, and the cross section of the positioning groove 510 is also triangular.

[0098] In addition, the corner of the positioning groove 510 is provided with a corner cleaning groove 520. The corner cleaning groove 520 can eliminate the stress concentration at the corner of the positioning groove 510, and prevent damage or jamming of the high-voltage bus patch panel 300 caused by sharp corners during insertion or removal.

[0099] For example, the corner cleaning groove 520 can be designed as a circular arc or a chamfer, and the specific shape is determined according to actual needs. And the size of the corner cleaning groove 520 should be moderate, which can eliminate sharp edges without affecting the overall structure and function of the positioning groove 510.

[0100] During installation, the conductive part 500 is installed on the support part 400, the operator inserts the joint 310 of the high-voltage bus patch panel 300 into the positioning groove 510 to ensure that the patch panel is in a preset position, and then controls the extrusion part 700 to fix the high-voltage bus patch panel 300 through the driving part 100.

[0101] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as a limitation, and thus, other examples of example embodiments can have different values.

[0102] It should be noted that similar reference numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0103] The above embodiments only express several implementation ways of the present application, and the description is more specific and detailed, but it should not be understood as a limitation to the scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
