[0002] During the handover test of electrical equipment in substations, various test devices are needed to detect the performance and parameters of the equipment to ensure that the equipment can operate safely and stably. However, the existing handover test devices have some shortcomings when used. On the one hand, a variety of small tools, such as screwdrivers, wrenches, test wire clamps, etc., are needed during the test, but the existing test devices lack a special tool placement area, resulting in the random placement of small tools, which not only easily causes the loss of tools, but also makes it difficult to find them when they are needed, affecting the test efficiency. On the other hand, when making electrical connections, it is necessary to insert the plug on the wire into the interface of the test device, but in actual operation, due to the lack of effective fixing measures, the plug is easily pulled or vibrated by external force and falls off, resulting in test interruption, and may even damage the test equipment and the equipment under test; the plug is also easy to loosen after being used for a long time, resulting in poor contact with the jack and cannot be used.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0018] like Figures 1 to 9 As shown, the improved substation electrical equipment handover test device includes a body 1, a tool box 2 is arranged on the side of the body 1, the tool box 2 has a transparent side wall 3, an inner wall filler 4 is arranged in the tool box 2, and the inner wall filler 4 has a plurality of grooves 5 matching various tools, each groove 5 corresponds to the upper end of the tool box 2 has a spring door 6, the groove 5 has two sides with a hollow cavity 7, the cavity 7 is connected with the groove 5, and the lower part of the transparent side wall 3 corresponding to the groove 5 is provided with a long strip hole 8, each long strip hole 8 is equipped with a push block 9, and the push block During the up and down movement of 9, the long strip hole 8 is always covered; the long strip hole 8 is connected to a push slider 10, and the push slider 10 is located in the groove 5; the push slider 10 is hinged to two connecting rods 11, and the two connecting rods 11 are respectively located in the cavity 7 on both sides of the groove 5, and a guide long groove 12 is opened on the connecting rod 11. A limit rod 13 is installed on the wall of the cavity 7, which is actually installed on the body 1. The limit rod 13 is located in the guide long groove 12. The connecting rod 11 is connected to a return spring 14, and one end of the return spring 14 is fixed to the connecting rod 11, and the other end is fixed to the body 1.
[0019] The upper end of the connecting rod 11 is connected to a clamping block 15 that can clamp the tool. The position of the clamping block 15 is preferably located where the tool has a variable diameter.
[0020] A number of jacks 16 are provided on the body 1. Inside each jack 16, there are two spring contact pieces 17, one on the left and one on the right. Next to each spring contact piece 17, an eccentric wheel 18 is installed. The eccentric wheel 18 is in contact with the spring contact piece 17. Above the eccentric wheel 18, a gear 19 is coaxially connected. The two gears 19 are meshed and connected; one of the gears 19 is coaxially connected to a rotating shaft 20. At the upper end of the rotating shaft 20, a rotating button 21 is installed. The rotating button 21 is located on the upper surface of the body 1.
[0021] The other gear 19 is coaxially connected to a ratchet mechanism. The ratchet mechanism includes a ratchet 22 and a pawl 221. The ratchet 22 is coaxially connected to the above-mentioned gear 19. The pawl 221 is equipped with a toggle lever 23. The toggle lever 23 is connected to a toggle shaft 24. At the upper end of the toggle shaft 24, a toggle button 25 is installed. The toggle button 25 is located on the upper surface of the body 1. By rotating the toggle lever 23, the pawl 221 can be disengaged from the restraint of the ratchet 22, enabling the ratchet 22 to rotate in reverse.
[0022] The toggle lever 23 can also be connected to a spring 222 to facilitate the return of the toggle lever 23.
[0023] The pawl 221, the toggle lever 23, and the spring 222 can all be installed on a partition 101 inside the body 1.
[0024] A fixture is provided next to each jack 16. The fixture includes a fixed arc plate 26 above and a sliding arc plate 27 below; the sliding mode of the sliding arc plate 27 is as follows: A convex-shaped sliding groove 28 in the up-down direction is opened below the fixed arc plate 26. Inside the sliding groove 28, a convex-shaped slider 29 is provided. The sliding arc plate 27 is fixedly connected to the convex-shaped slider 29; a return compression spring 30 is provided inside the sliding groove 28.
[0025] The working process is as follows: Through the transparent side wall 3 from the outside, find the mold cavity 5 where the desired tool is located, open the corresponding spring door 6, take out the desired tool. When taking it out, the push block 9 can be pushed upward. The push block 9 drives the push slider 10 to push the tool upward. During the upward movement of the push slider 10, the clamping block 15 is driven away from the tool through the connecting rod 11, losing the restraint on the tool; when putting the tool in, perform the same operation, open the spring door 6, push the push block 9 upward, then put the tool into the mold cavity 5, and then release the push block 9; during the operation, the stroke of the push slider 10 does not have to be too large, as long as it does not prevent the tool from being taken out.
[0026] Insert the plug into the jack 16, turn the rotary button 21, so that the eccentric wheel 18 rotates, gradually making the two spring contacts 17 clamp the plug until it can no longer be turned. At the same time, with the cooperation of the ratchet mechanism, the eccentric wheel 18 cannot reverse, so that the plug cannot become loose. No matter how long the time is, even if the plug and the spring contacts 17 are worn, the plug will not become loose.
[0027] When removing the plug, turn the toggle button 25, so that the toggle rod 23 drives the pawl 221 away from the ratchet 22, releasing the restraint of the pawl 221 on the ratchet 22. The ratchet 22 can then rotate in reverse, and at this time the plug can be pulled out.
[0028] After the plug is inserted into the jack 16, first bend a part of the wire 31 behind the plug, and then place the wire 31 into the fixture. In this way, even if the wire 31 is pulled by an external force, it will not affect the connection between the plug and the wire 31. That is to say, when the wire 31 is subject to an external force, the plug will not be affected.
