Description

Technical Field

[0001] The invention belongs to the technical field of cable testing, and in particular relates to a connecting device for cable testing and a use method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the operation and maintenance of modern power systems, cable testing is a key link to ensure the safety and stable power supply of cable lines. With the continuous expansion of the scale of power grids and the continuous improvement of power supply reliability requirements, how to efficiently complete cable testing tasks within a limited time window has become an important issue that needs to be solved in the power industry.

[0004] In the traditional cable testing method, when the cable needs to be tested, the staff must first remove the cable plug from the cabinet. This process requires the operator to have superb skills to avoid damage to the plug and surrounding components. Then, according to the normal process, the stress cone and the boot head must be removed one by one using special tools. As a key insulating component of the cable terminal, the stress cone requires precise operation to prevent damage to the insulation performance; the removal of the boot head is also cumbersome and involves the release of multiple buckles or fastening devices. Only after completing the above disassembly can the subsequent connection preparations with the test equipment be carried out, including cleaning the cable nose and selecting suitable connection accessories. Finally, the cable is connected to the test tool using the ordinary connection method. This process often requires repeated debugging due to loose connections or mismatched accessories.

[0005] It can be seen that the traditional cable test operation involves a series of complicated processing steps after the cable plug is removed from the cabinet, especially the disassembly and reinstallation of the stress cone and the boot head, which not only consumes a lot of manpower and material resources, but also easily introduces hidden dangers of human failure due to improper operation, which seriously restricts the improvement of test efficiency. In addition, disassembling the stress cone and the boot head can easily cause damage to the connection position, making it impossible to continue to use it, which increases the cost of the test and reduces efficiency. Summary of the invention

[0028] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0029] Traditional cable test operations involve a series of complex processing steps after the cable plug is removed from the cabinet, especially the disassembly and reinstallation of the stress cone and the boot head. This not only consumes a large amount of manpower and material resources, but also easily introduces potential human faults due to improper operation, seriously restricting the improvement of test efficiency. Moreover, disassembling the stress cone and the boot head easily causes damage to the connection position, resulting in inability to continue use, which increases the cost of the test and is inefficient.

[0030] Embodiment 1:

[0031] The following will describe the present invention in detail with reference to the attached drawings. A connection device for cable test disclosed in this embodiment is asFigure 1 As shown in the figure, it includes a first connection mechanism and a second connection mechanism. One end of the first connection mechanism is connected to the second connection mechanism;

[0032] As Figure 2 shown in the figure, the first connection mechanism includes a first connection column, a first outer housing, a connection disk, and a first cylindrical connection head; the first connection column is sleeved with the first outer housing, one end of the first outer housing is provided with the connection disk, and one end of the connection disk is provided with the first cylindrical connection head; the second connection mechanism includes a second connection column, a second outer housing, and a second cylindrical connection head. The second connection column is sleeved with the second outer housing, one end of the second connection column is provided with a circular groove, and the second cylindrical connection head is arranged in the circular groove.

[0033] The first cylindrical connection head of the first connection mechanism is connected to the test wire clamp, and the second cylindrical connection head of the second connection mechanism is connected to the cable plug. Then, the cable is connected to the test tool to perform the cable test. It is not necessary to disassemble and assemble the boot head and stress cone of the cable plug to perform the cable test, thus avoiding damage during the disassembly and assembly process. The transfer is realized through the first connection mechanism and the second connection mechanism, improving the efficiency of the cable test.

[0034] The connection column, connection disk, and cylindrical connection head are made of high-strength and high-conductivity alloy materials, and have an interface design that can accurately fit the cable nose. Without damaging the nose, it can achieve a tight and reliable mechanical and electrical connection, facilitating single-handed operation by the staff and being more labor-saving.

[0035] The first connection column and the first outer housing are detachably connected, and the length of the first outer housing is the same as that of the first connection column. The second connection column and the second outer housing are detachably connected, and the length of the second outer housing is the same as that of the second connection column.

[0036] Both the first connection column and the first outer housing, and the second connection column and the second outer housing are detachably connected. When the first outer housing and the second outer housing are damaged, a new outer housing can be replaced to avoid safety accidents caused by electric leakage during the test.

[0037] A threaded hole is provided at the other end of the first connection column, and a connection bolt is provided at the other end of the second connection column. The connection bolt is screwed into the threaded hole to connect the first connection column and the second connection column. By connecting the first connection column and the second connection column through the connection bolt and the threaded hole, the first connection column and the second connection column can be disassembled when not in use, which is convenient for carrying, and can be quickly connected when in use.

[0038] One end of the first connecting column is fixedly connected to one end of the connecting plate, and the other end of the connecting plate is fixedly connected to one end of the first cylindrical connecting head. An external thread is provided on the outer surface of the first cylindrical connecting head, and the first cylindrical connecting head is connected to the test wire clamp. One end of the second cylindrical connecting head is fixedly connected to the bottom surface of the circular groove, and one end of the second cylindrical connecting head is connected to the boot head.

[0039] Through the external thread on the first cylindrical connecting head, the surface of the first cylindrical connecting head has protrusions, which facilitates the test wire clamp to clamp the first cylindrical connecting head and prevents the test wire clamp from falling off during the test.

[0040] The cable plug includes a boot head and a stress cone. In conventional cable tests, the boot head and the stress cone are disassembled, and then the stress cone is clamped by the test wire clamp for testing. By connecting the second cylindrical connecting head to the boot head, the disassembly and assembly of the boot head and the stress cone are avoided, and the efficiency of cable testing is improved.

[0041] The wire clamp adopts an elastic adaptive design, which can flexibly adjust the clamping force according to different specifications of cables to ensure that the cables will not loosen and fall off during the test; the quick plug integrates a standardized interface and a self-locking function, and only needs to be inserted and screwed gently to achieve a firm connection with the test tool, greatly improving the connection speed.

[0042] The first outer housing and the second outer housing are cylindrical housings, and both the first connecting column and the second connecting column are cylindrical structures. The first outer housing and the second outer housing are both made of insulating materials to avoid electric leakage during cable testing and improve safety.

[0043] Embodiment 2:

[0044] A method for using a connecting device for cable testing includes the following steps:

[0045] The connecting bolt at one end of the second connecting column is screwed into the threaded hole at one end of the first connecting column to connect the first connecting mechanism and the second connecting mechanism. Then, the test wire clamp is clamped on the first cylindrical connecting head, the second cylindrical connecting head is inserted into the cable plug, and the second connecting column is pressed to connect the second cylindrical connecting head and the cable plug. Then, the cable is connected to the test tool to perform cable testing.

[0046] Specifically, first, the operator steadily removes the cable plug from the cabinet according to the standard procedure, takes out the connecting device, directly aligns it with the cable nose in the cable plug, and gently rotates or presses it to complete the quick connection. The stress cone and the boot head do not need to be disassembled during the whole process and remain in place. According to the interface type of the test tool, select the appropriate wire clamp or quick plug, and conveniently connect the cable with the connected connecting device to the test tool to immediately carry out cable testing.

[0047] The connection device of the present invention can significantly improve work efficiency, eliminate the disassembly and reinstallation steps of the stress cone and the boot head, save the pre - preparation time, enable the cable test to start quickly, and provide sufficient time guarantee for timely discovering potential cable problems.

[0048] Reduce the operation difficulty and manpower requirements. The operator does not need to master complex stress - cone disassembly skills and can easily complete the connection operation alone, reducing the manpower input. At the same time, it reduces the risk of component damage caused by human operation errors. Improve the connection reliability. The special connection device, in cooperation with the wire clamp and the quick - plug, ensures the connection stability of the cable during the test, effectively avoiding test - data deviation or interruption problems caused by loose connection and guaranteeing the accuracy of the test results.

[0049] Although the specific implementation mode of the present invention is described above in conjunction with the accompanying drawings, it is not a limitation of the protection scope of the present invention. Those skilled in the art should understand that, based on the technical solution of the present invention, various modifications or deformations that can be made without creative labor by those skilled in the art are still within the protection scope of the present invention.
