Description

Technical Field

[0001] This utility model belongs to the field of relay protection testing technology, specifically an auxiliary device for relay protection testing lines. Background Technology

[0002] Relay protection devices are devices used in power systems to protect electrical equipment and ensure the safe operation of the system. They can disconnect faulty components from the power system when a fault occurs or an abnormal operation occurs, thereby reducing damage to the electrical equipment.

[0003] Existing relay protection devices need to be tested regularly to observe whether their performance is normal. During testing, testing instruments are used to connect the circuit to the relay protection device, and then the performance of the relay protection device is observed through the data on the testing instruments. During long-term use and observation, it was found that the existing testing instruments connect to the relay protection device through the circuit. When a large number of circuits need to be connected, the circuits may become tangled and knotted when the circuits are moved.

[0004] Therefore, this utility model provides an auxiliary device for relay protection test lines. Utility Model Content

This ensures that there is a gap between multiple wires, reducing the possibility of tangling and knotting when moving the wires, thus improving stability during use. Simultaneously, the elastic action of the spring rods and elastic plates facilitates the handling of the wires, improving ease of use.

[0007] Preferably, the connecting assembly includes a fixed base; the fixed base is fixedly connected to the top of the support leg; a bidirectional screw is rotatably connected to the middle of the fixed base; a pair of first sliders are connected to the screw-nut pair in the middle of the bidirectional screw; a connecting rod is hinged to the top of the first slider; a connecting plate is hinged to the ends of the pair of connecting rods; the connecting plate is fixedly connected to the bottom of the fixed plate; a turntable is fixedly connected to the end of the bidirectional screw; a handle is fixedly connected to the side wall of the turntable; with the above structure, the bidirectional screw connects the first sliders, and the connecting rod connects the connecting plate and the fixed plate. The first sliders can be moved closer or further apart by the rotation of the bidirectional screw. At this time, the height of the fixed plate can be adjusted to rise or fall to accommodate relay protection devices of different heights and improve the applicability during use.

[0008] Preferably, a slide rail is fixedly connected to the top of the fixing plate; a plurality of second sliders are slidably connected inside the slide rail; a fixing ring is fixedly connected to the top of the second slider; a first limiting hole is opened on the side wall of the second slider; a plurality of second limiting holes are opened on the side wall of the slide rail; a fixing pin is slidably engaged in the first limiting hole and the second limiting hole; with the above structure, the slide rail connects the second slider and the fixing ring, and the first limiting hole and the fixing pin are used in conjunction to facilitate the adjustment of the position of the interface between the wire and the relay protection device, so that the interface between the wire and the relay protection device is close or horizontal, reducing the situation where the wire falls off due to the large tilt angle between the wire and the relay protection device.

[0009] Preferably, an extension plate is fixedly connected to the middle of the support leg; multiple bolts are threaded into the extension plate; through the above structure, the extension plate connects the support leg and multiple bolts, which facilitates the adjustment of the top fixing plate to a horizontal state, thereby reducing the possibility of the fixing plate becoming skewed due to uneven ground.

[0010] Preferably, the side wall of the fixing plate is fixed with multiple hooks; the multiple hooks are distributed in a linear array; through the above structure, the hooks are connected to the fixing plate, which facilitates the support and separation of the wires when they are temporarily placed, thereby improving the convenience of temporarily placing the wires and reducing the situation of the wires tangling together.

[0011] Preferably, a rubber pad is fixedly connected inside the limiting groove; the rubber pad has an arc-shaped structure; through the above structure, the rubber pad can reduce the friction between the wire and the limiting groove when the wire moves in the limiting groove, thus reducing the damage to the surface of the wire.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown in the embodiment of this utility model, an auxiliary device for a relay protection test line includes a fixed plate 1; a fixed platform 11 is fixedly connected to the top of the fixed plate 1; multiple limiting grooves 12 are opened on the top of the fixed platform 11; multiple sets of baffles 13 are fixedly connected to the top of the fixed platform 11; a set of baffles 13 are symmetrically arranged on both sides of the limiting grooves 12; multiple spring rods 14 are slidably connected to the side walls of the baffles 13; an elastic plate 15 is fixedly connected to the side wall of the baffles 13 away from the spring rods 14; the ends of the spring rods 14 are fixedly connected to the inner side wall of the elastic plate 15; a connecting assembly is provided at the bottom of the fixed plate 1; a support leg 16 is fixedly connected to the bottom of the connecting assembly; during operation, when testing the relay protection device, the tester's line is placed between the elastic plates 15 on both sides, and then the line is pressed down into the limiting grooves 12. At this time, the line will compress and deform the elastic plate 15. At this point, the spring rod 14 can be stretched, and the wire will pass between the elastic plates 15 on both sides and be placed in the limiting groove 12 below. At this time, the spring rod 14 will retract and rebound, causing the elastic plate 15 to return to its original position. This can restrict the wire within the limiting groove 12. When the test is over, the wire is pulled upward. At this time, the wire squeezes the elastic plate 15, causing the spring rod 14 to stretch, and the wire can be taken out from the limiting groove 12. Through the above structure, multiple limiting grooves 12 are set in conjunction with the spring rod 14 and the elastic plate 15. When testing the relay protection device, the wire of the testing instrument can be respectively stuck in the limiting groove 12. This can keep the multiple wires spaced apart, so as to reduce the situation of tangling and knotting when moving the wires, thereby improving the stability during use. At the same time, the elastic action of the spring rod 14 and the elastic plate 15 can facilitate the handling of the wires, thereby improving the convenience of use.

[0026] like Figure 1 and Figure 2As shown, the connecting assembly includes a fixed base 2; the fixed base 2 is fixedly connected to the top of the support leg 16; a bidirectional screw 21 is rotatably connected to the middle of the fixed base 2; a pair of first sliders 22 are connected to the screw nut pair in the middle of the bidirectional screw 21; a connecting rod 23 is hinged to the top of the first slider 22; a connecting plate 24 is hinged to the ends of the pair of connecting rods 23; the connecting plate 24 is fixedly connected to the bottom of the fixed plate 1; a turntable 25 is fixedly connected to the end of the bidirectional screw 21; a handle 26 is fixedly connected to the side wall of the turntable 25; during operation, when the height of the relay protection device to be tested is different, the bidirectional screw 21 can be driven by rotating the turntable 25. Rotating the first slider 22 allows it to slide towards each other. When the first sliders 22 approach each other, the connecting rod 23 can be lifted, thus raising the position of the fixed plate 1. When the first sliders 22 move away from each other, the position of the fixed plate 1 can be lowered. Through the above structure, a bidirectional screw 21 is set to connect the first sliders 22, and the connecting rod 23 connects the connecting plate 24 and the fixed plate 1. The first sliders 22 can be moved closer or further apart by rotating the bidirectional screw 21. At this time, the height of the fixed plate 1 can be adjusted to rise or fall to accommodate relay protection devices of different heights and improve its applicability during use.

[0027] like Figure 1 and Figure 4 As shown, a slide rail 3 is fixedly connected to the top of the fixed plate 1; multiple second sliders 31 are slidably connected inside the slide rail 3; a fixing ring 32 is fixedly connected to the top of the second slider 31; a first limiting hole 33 is opened on the side wall of the second slider 31; multiple second limiting holes 34 are opened on the side wall of the slide rail 3; a fixing pin 35 is slidably engaged in the first limiting hole 33 and the second limiting hole 34; during operation, after the line of the testing instrument is limited in the limiting groove 12, the end of the wire is passed through the fixing ring 32 and then connected to the relay protection device. When the interface distance of the relay protection device is different, the fixing pin 35 can be removed from the first limiting hole 33 and the second limiting hole 34. Then, the second slider 31 slides within the slide rail 3. At this time, the fixing ring 32 can be adjusted to change position. When it moves close to or horizontally to the structure of the relay protection device, the fixing pin 35 is inserted into one of the second limiting holes 34 and the first limiting hole 33 to fix the position of the second slider 31. Through the above structure, the slide rail 3 connects the second slider 31 and the fixing ring 32. The first limiting hole 33 and the fixing pin 35 are used in conjunction to facilitate the adjustment of the position of the interface between the wire and the relay protection device, so that the interface between the wire and the relay protection device is close to or horizontal, reducing the situation where the wire falls off due to the large tilt angle between the wire and the relay protection device.

[0028] like Figure 1 and Figure 5As shown, an extension plate 4 is fixedly connected to the middle of the support leg 16; multiple bolts 41 are threadedly connected to the extension plate 4; during operation, when the ground is uneven, the upper fixing plate 1 will tilt when the support leg 16 is placed on the ground. At this time, the height of the support leg 16 relative to the ground can be adjusted by rotating the bolts 41, so that the top fixing plate 1 becomes horizontal. Through the above structure, the extension plate 4 is set to connect the support leg 16 and multiple bolts 41, which makes it easy to adjust the top fixing plate 1 to a horizontal state, so as to reduce the situation where the fixing plate 1 tilts due to uneven ground.

[0029] like Figure 1 As shown, the side wall of the fixing plate 1 is fixed with multiple hooks 5; the multiple hooks 5 are arranged in a linear array; during operation, when it is necessary to temporarily place the wire, the wire can be wound around the hook 5 respectively. At this time, the hook 5 supports the wire and separates multiple wires. When it is needed to use it again, it can be removed from the hook 5 respectively. Through the above structure, the hooks 5 are set to connect the fixing plate 1, which can facilitate the support and separation of the wire when it is temporarily placed, so as to improve the convenience of temporarily placing the wire and reduce the situation of the wires tangling together.

[0030] like Figure 3 As shown, a rubber pad 6 is fixedly connected inside the limiting groove 12; the rubber pad 6 has an arc-shaped structure; during operation, when the wire is limited in the limiting groove 12, the wire will contact the rubber pad 6. Through the above structure, the rubber pad 6 can reduce the friction between the wire and the limiting groove 12 when the wire moves in the limiting groove 12, which may cause damage to the surface of the wire.

[0031] like Figure 2 As shown, the handle 26 is fixedly connected to the side wall with an anti-slip sleeve 7. When working, when the handle 26 is held and the turntable 25 is rotated, it will come into contact with the anti-slip sleeve 7 on the surface of the handle 26. Through the above structure, the anti-slip sleeve 7 is connected to the handle 26, which can reduce the slippage when the handle 26 is held and rotated, thereby improving the stability of rotating the handle 26.

[0032] Working principle: When testing the relay protection device, the tester's wire is placed between the two elastic plates 15, and then the wire is pressed down into the limiting groove 12. At this time, the wire will compress the elastic plate 15 and deform, which will stretch the spring rod 14. Then the wire will pass between the two elastic plates 15 and be placed in the lower limiting groove 12. At this time, the spring rod 14 will retract and rebound, causing the elastic plate 15 to return to its original position. This will confine the wire within the limiting groove 12. When the test is completed, the wire is pulled upwards, at which point the wire compresses the elastic plate 15 and... When the spring rod 14 is stretched, the wire can be removed from the limiting groove 12. When the heights of the relay protection devices to be tested are different, the bidirectional screw 21 can be rotated by rotating the turntable 25. At this time, the first sliders 22 can slide in opposite directions. When the first sliders 22 are close to each other, the connecting rod 23 can be lifted, which can lift the fixing plate 1 and raise its position. When the first sliders 22 are far apart, the position of the fixing plate 1 can be lowered. After limiting the circuit of the testing instrument in the limiting groove 12, the end of the wire is passed through the fixing ring. Inside 32, it is then connected to the relay protection device. When the interface distance of the relay protection device is different, the fixing pin 35 can be removed from the first limiting hole 33 and the second limiting hole 34, and then the second slider 31 can slide in the slide rail 3. At this time, the fixing ring 32 can be adjusted to adjust its position. When it moves close to or horizontal to the structure of the relay protection device, the fixing pin 35 can be inserted into one of the second limiting holes 34 and the first limiting hole 33 to fix the position of the second slider 31. When the ground is uneven, when the support leg 16 is placed on the ground, it will... The upper fixing plate 1 is tilted. At this time, the height of the support leg 16 relative to the ground can be adjusted by rotating the bolt 41, so that the top fixing plate 1 becomes horizontal. When the wire needs to be temporarily placed, the wire can be wound around the hook 5. At this time, the hook 5 supports the wire and separates multiple wires. When it is needed to use it again, it can be removed from the hook 5. When the wire is limited in the limiting groove 12, the wire will contact the rubber pad 6. When the handle 26 is held and the turntable 25 is rotated, it will contact the anti-slip sleeve 7 on the surface of the handle 26.
