Description

Technical Field

[0001] The invention relates to the field of relay protection tester auxiliary tools, and in particular to a novel relay protection test line package box. Background Art

[0002] The relay protection test line is a copper core soft wire used for testing and experimenting relay protection devices in power systems. It consists of a test line plug and a test line body. Relay protection test lines can be divided into three types: current type, voltage type, and signal type. The relay protection test line package is a device for storing relay protection test lines. The traditional relay protection test line package is a simple line package. When storing relay protection test lines, since the test lines are copper core soft wires, they are easy to get tangled when stored together. When taking out the relay protection test lines, they need to be straightened again, untied and pulled out one by one before they can be used for experiments.

[0003] The traditional relay protection test line packaging box has the following main disadvantages: 1. When storing the relay protection test line, since the relay protection test line is a copper core soft wire, it is easy to get tangled and entangled with each other, squeeze and rub against each other during storage and movement, causing the insulation layer of the relay protection test line to be damaged, and seriously causing the copper core to break, and the relay protection test line to be scrapped. Reduce the service life of the relay protection test line. 2. When storing the relay protection test line, since the test line is a copper core soft wire, it is easy to get tangled and entangled with each other when stored together. When taking out the relay protection test line, it is necessary to straighten it again, untie the knot and pull it out one by one. It is extremely time-consuming and labor-intensive, cumbersome and complicated, and reduces the efficiency of relay protection device testing and experiments. 3. When storing the relay protection test line, all types of relay protection test lines are stacked together, entangled and mixed with each other, and cannot be placed by type. When taking out for use, they cannot be taken out by type, and the functionality is poor. Summary of the invention

[0004] In view of the above problems, it is necessary to provide a new relay protection test line package box. The new relay protection test line package box is convenient for classifying and storing various relay protection test lines, so as to facilitate taking out and storing, and prevent the relay protection test lines from being tangled and worn.

[0007] Preferably, each of the central axes comprises a stretching rod, a stretching sleeve and two spring latches, one end of the stretching rod is connected to the limit block, one end of the stretching sleeve is connected to the base, the other end of the stretching sleeve is movably sleeved on an end of the stretching rod away from the limit block, the two spring latches are respectively mounted on both ends of the stretching sleeve, one end of each of the spring latches passes through the stretching sleeve and abuts against the stretching rod, and the stretching rod can slide along the inner wall of the stretching sleeve when the two spring latches are loose.

[0008] Preferably, the cross-sectional area of ​​the central axis is smaller than the cross-sectional areas of the limiting block and the base, respectively.

[0009] Preferably, each of the limit blocks, each of the central axis and each of the bases are cylindrical.

[0010] Preferably, outer surfaces of the plurality of fixed shafts are all frosted surfaces.

[0011] Preferably, the first jack and the second jack are respectively adapted to the sizes of plugs at both ends of each relay protection test line.

[0012] Preferably, each of the first insertion holes is respectively opened on the side surface or the top surface of each of the limiting blocks.

[0013] Preferably, the lower end surfaces of the plurality of bases are completely in contact with the inner bottom of the box body, and each of the second plug holes is provided on a side surface of each of the bases.

[0014] Preferably, the package box body is a cube.

[0015] Preferably, the heights of the plurality of fixed shafts are all smaller than the height of the box body.

The lower end surfaces of the six bases 6 are all in full contact with the inner bottom of the package body 1, and each second socket 8 is provided on the side of each base 6.

[0026] Each central axis 5 includes a stretching rod 51, a stretching sleeve 52 and two spring latches 53. One end of the stretching rod 51 is connected to the limit block 4, and one end of the stretching sleeve 52 is connected to the base 6. The other end of the stretching sleeve 52 is movably sleeved on the end of the stretching rod 51 away from the limit block 4. The two spring latches 53 are respectively installed at the upper and lower ends of the stretching sleeve 52, and one end of each spring latch 53 passes through the stretching sleeve 52 and abuts against the stretching rod 51. The stretching rod 51 can slide along the inner wall of the stretching sleeve 52 when the two spring latches 53 are loose.

[0027] When the novel relay protection test line package box of the present invention is used, the box cover 3 is opened, and the two spring pins 53 of the central axis 5 of the first fixed axis 21 are first loosened to adjust the height of the stretching rod 51, and then one end plug of the current type relay protection test line is inserted into the second jack 8 of the first fixed axis 21. After fixing, the current type relay protection test line is wound upward along the first fixed axis 21, and then the other end plug is inserted into the first jack 7 of the first fixed axis 21. In this way, the current type relay protection test line is firmly and tightly fixed around the first fixed axis 21. Even if the package body 1 is allowed to move and vibrate, the current type relay protection test line inside will not be tangled or entangled, and will not rub or squeeze each other to cause damage to its insulation layer or even breakage of the copper core.
