Description
Technical Field
[0001] The utility model belongs to the technical field of relay protection testing, and particularly relates to a power relay protection test rack. Background Art
[0002] The relay protection device is an important testing tool to ensure the safe and reliable operation of the power system. With the continuous expansion of the scale of modern power systems, the requirements for the reliability and efficiency of power system operation and management are constantly increasing. The testing work of relay protection personnel has become more frequent and complex. When testing relay protection devices, a test rack is needed to display various devices, such as relay protection devices, relay protection testing equipment, simulation master stations, switches, DC power supplies, and other devices.
[0003] The existing relay protection test rack lacks a fixing structure for test equipment during use. During the test, the test equipment is prone to displacement or even falling due to external factors; at the same time, there is also a lack of a protection mechanism for power cords. There are many test equipment, so there are many power cords and signal lines during testing, and they are chaotic. Once you are not careful when walking, you will pull the wires, resulting in the wires falling off from the interfaces of the equipment, thus affecting the testing work. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a power relay protection test rack to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1:
[0023] Please refer to Figure 1 - Figure 2 as shown, a power relay protection test stand includes:
[0024] A fixing component 1, the fixing component 1 includes a support plate 11, a groove 12 is opened on one side of the support plate 11, two threaded blocks 14 are movably installed inside the groove 12, two clamping plates 16 are movably installed on one side of the support plate 11, and the threaded block 14 is fixedly connected to the clamping plate 16;
[0025] A wire fixing component 2, the wire fixing component 2 is arranged on one side of the support plate 11, the wire fixing component 2 includes a first wire fixing plate 21 fixedly installed on one side of the support plate 11, a second wire fixing plate 22 is movably installed on one side of the first wire fixing plate 21, and a plurality of wire grooves 23 are opened on one side of the first wire fixing plate 21 and the second wire fixing plate 22.
[0026] Specifically, a groove 12 is formed on one side of the support plate 11. Inside the groove 12, two threaded rods 13 are movably installed through bearings. The two threaded rods 13 are fixedly connected to each other. The threads on the outer sides of the two threaded rods 13 are opposite. Threaded blocks 14 are installed on the outer sides of the two threaded rods 13 by screwing. The threaded blocks 14 are slidably fitted with the inner wall of the groove 12. A handwheel 15 is movably installed on the outside of the support plate 11 near the groove 12. The handwheel 15 is connected to the shaft of the threaded rod 13 by transmission. Two clamping plates 16 are movably installed at the top of the support plate 11. The two clamping plates 16 are symmetrically arranged. One side of the two clamping plates 16 close to the threaded block 14 is fixedly connected to the threaded block 14. A rubber strip 17 is fixedly installed on one side of the clamping plate 16. There are three support plates 11 in total. A support rod 18 is connected between the support plates 11. Four corners on one side of the bottom of the support plate 11 are fixedly installed with feet 19.
[0027] As can be seen from the above, two movable clamping plates 16 are provided on one side of the support plate 11 to limit the device on both sides of the device, so as to prevent the device from being displaced or even dropped due to external force factors during testing. Since the threads on the outer sides of the two threaded rods 13 are opposite, when the threaded rods 13 rotate, the two threaded blocks 14 will move towards or away from each other, and synchronously drive the two clamping plates 16 to approach or move away from each other.
[0028] During specific use, first rotate the handwheel 15. The handwheel 15 drives the threaded rod 13 to rotate. Then, the threaded rod 13 drives the two threaded blocks 14 to approach each other, and synchronously drives the clamping plates 16 to approach the device until the clamping plates 16 clamp the device.
[0029] Embodiment 2:
[0030] Please refer to Figure 1 and Figure 3 As shown in the figure, a first wire fixing plate 21 is fixedly installed on one side of the top of the support plate 11. A second wire fixing plate 22 is movably installed on the side of the first wire fixing plate 21 away from the support plate 11. A plurality of wire grooves 23 are formed on one side of the first wire fixing plate 21 and the second wire fixing plate 22. Two limiting rods 24 are fixedly installed on the side of the support plate 11 close to the first wire fixing plate 21. The two limiting rods 24 are symmetrically arranged on both sides of the first wire fixing plate 21.
[0031] Specifically, limiting disks 25 are fixedly installed at the tops of the two limiting rods 24. Limiting blocks 26 are movably sleeved on the outer sides of the two limiting rods 24. One side of the limiting block 26 close to the second wire fixing plate 22 is fixedly connected to the second wire fixing plate 22. A return spring 27 is connected between the limiting block 26 and the limiting disk 25. A pulling block 28 is fixedly installed on the side of the second wire fixing plate 22 away from the first wire fixing plate 21.
[0032] As can be seen from the above, a first wire fixing plate 21 and a second wire fixing plate 22 are provided on one side of the support plate 11. Under the action of the return spring 27, the second wire fixing plate 22 closely adheres to one side of the first wire fixing plate 21. The wire grooves 23 are used to clamp and fix the power cords, signal wires and other wires of the device. After the positions of the wires are limited, even if they are pulled, the ends of the wires are not easily separated from the wiring ports of the device.
[0033] During specific use, first pull the pull block 28 to make the second wire fixing plate 22 away from the first wire fixing plate 21. At this time, the return spring 27 is in a stressed state. Then pass the wire through the space between the first wire fixing plate 21 and the second wire fixing plate 22. Then release the pull block 28, and the second wire fixing plate 22 will press on one side of the wire under the action of the return spring 27, thus fixing the wire.
