[0002] The relay protection tester connects the relays of different devices through the experimental lines, namely the test lines. Generally, the experimental lines of the relay protection tester require different test lines according to different devices, and the test lines will be tangled together when stored, so it takes a lot of time to select them during testing.

[0003] Therefore, a relay protection test line auxiliary device in the prior art has a publication number of CN220115979U. When testing the relay protection, the device can insert a plug into the connection port between the relay protection device and the relay protection tester, release the locking fixation of the gear by the guide rod, and rotate the winding wheel by the turntable to wind the excess test line into the interior of the protective box for protection. When winding, the test line can be guided by the test line and the guide wheel. After the test line is wound to a suitable length, the guide rod can be loosened and engaged with the gear to limit the rotation of the winding wheel.

[0004] However, because a general relay protection tester is equipped with a large number of test wires for selection or replacement, it is necessary to carry a large number of existing technologies, which increases the weight and the space occupied by carrying. Therefore, the existing technology has certain shortcomings when carrying a large number of test wires. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, a relay protection test line auxiliary device includes a detector 1 for testing a relay protector. The detector 1 can select any type of relay protection gas detector commonly used in the market. A plurality of stacked pads 11 are arranged on the detector 1. The stacked pads 11 are used to separately store a plurality of test lines, and the number of stacked pads 11 increases or decreases accordingly with the number of test lines. A mesh cover plate 5 is gap-fitted and fixedly connected to the upper surface of the pad 11. One side of the mesh cover plate 5 is open, and an insertion port 9 is provided at the top edge of the opening of the mesh cover plate 5. A plurality of convex plugs are inserted into the insertion port 9. Block 6, the bottom edge of the protrusion 6 is fixedly connected with a partition 10 slidably connected to the upper surface of the pad 11, so that a corresponding number of protrusions 6 can be placed along the opening of the grid cover 5 through the open end of the insertion port 9, thereby realizing the adjustment of the number of partitions 10 on the pad 11, and a wire groove 15 for storing the test line is formed between two adjacent partitions 10 between the grid cover 5 and the pad 11. By adjusting the number of partitions 10 on the pad 11, the number of wire grooves 15 on the pad 11 can be adjusted, so as to place more test lines, and the width of the wire groove 15 can be adjusted according to the length of the test line.

[0024] In order to ensure the stability of the sliding direction of the partition 10: the upper surface of the pad 11 is located at the adjacent two sides of the opening of the grid cover 5, and is respectively fixedly connected with a guide rail 12 inserted into one side of the bottom edge of the partition 10, and a guide groove 14 is provided for sliding connection with the other side of the bottom edge of the partition 10. The guide rail 12 and the guide groove 14 are arranged in parallel. Through the cooperation between the partition 10 and the guide rail 12 and the guide groove 14, the partition 10 can be realized by sliding on the pad 11 by moving the protrusion 6.

[0025] In order to fix the spacing of the wire groove 15: a pin shaft 7 is inserted into one side of the upper surface of the protrusion 6, and a plurality of positioning holes 8 for threaded connection with the pin shaft 7 are opened on the upper surface of the grid cover 5. By moving the protrusion 6 so that the protrusion 6 is threadedly connected to the positioning holes 8 at different positions through the pin shaft 7, it is convenient to fix the protrusion 6 and the partition 10 connected to the protrusion 6 on the pad 11, so as to achieve the spacing between two adjacent partitions 10, that is, adjust the width of the wire groove 15.

[0026] In order to facilitate personnel to adjust the placement position of the test line in the wire slot 15: a plurality of transverse slots 13 for adjusting the position of the test line and arranged parallel to the insertion port 9 are opened on the upper surface of the grid cover 5, so that the position of the test line can be adjusted after the test line is placed in the wire slot 15, so that the test line fits the side wall of the partition 10.

[0027] In order to facilitate personnel to adjust the position of the protrusion 6: the upper surface of the detector 1 is threadedly connected with a screw rod 2 that passes through one side of several pads 11, and the lower surface of the pad 11 is rotatably connected with a nut 4 that is threadedly connected to the screw rod 2. The upper surface of the detector 1 is located at one of the opposite side corners of the several pads 11, and the insertion rod 3 and the baffle bar 16 for placing the pad 11 for rotation are respectively inserted. The position of the pad 11 on the screw rod 2 can be adjusted by rotating the nut 4, and the pad 11 is rotatably connected to the nut 4. Therefore, personnel can rotate any pad 11 by pulling out the insertion rod 3 and the baffle bar 16, so that the pad 11 is separated from the stacked pads 11, which makes it convenient for personnel to adjust the position of the protrusion 6 on the rotated pad 11.

[0028] In terms of usage, according to the length of the test line, the personnel moves the protrusion 6 to realize that the partition 10 is installed on the pad 11 along the open end of the insertion port 9, and the protrusion 6 is fixed on the grid cover 5 by plugging the pin 7 with the corresponding position positioning hole 8, and adjusts the width of the fixed wire groove 15, puts one end of the test line into the wire groove 15, and adjusts the position of the test line in the wire groove 15 through the transverse groove 13, so that the test line fits the side wall of the partition 10, and then installs the screw 2, the plug rod 3 and the baffle 16 on the detector 1, and installs the pad 11 on the screw 2 by rotating the nut 4, and realizes that the pad 11 is installed on the detector 1 in a stacked state by contacting the plug rod 3 and the baffle 16. When taking it, you only need to pull out the plug rod 3 and the baffle 16 to realize the rotation of any one of the pads 11, and the test line on the pad 11 can be taken.
