Description

Technical Field

[0001] The utility model relates to the technical field of relay protection, in particular to a portable debugging device based on relay protection. Background Art

[0002] A relay protection system is a system that automatically removes faulty equipment from the system in the shortest possible time and smallest area when a fault or abnormal operating condition occurs in the power system, or sends a signal to the on-duty personnel to eliminate the root cause of the abnormal condition, so as to reduce or avoid damage to the equipment and the impact on power supply to adjacent areas.

[0003] The relay protection system protects the power system by automatically disconnecting the contacts inside the relay when a fault or abnormal operating condition occurs inside the power system. However, sometimes the relay protection system may malfunction or fail to operate due to stuck relay contacts or current inside the power system exceeding the relay operating range, or other reasons that affect the normal operation of the relay protection system. Therefore, the relay protection system must be debugged before being put into use in the power system. In order to facilitate the debugging of the relay protection system, R&D personnel have developed a debugging device for relay protection. When it is in use, since the relay protection system being debugged is itself in the debugging stage and is extremely unstable, after the relay protection system is connected to the debugging plug board on the debugging device, arcing and overheating may occur, resulting in damage to the plug board of the debugging device, but it is very difficult to replace, which leads to delays in the debugging progress. In addition, traditional relay protection debugging devices are often fixed and inconvenient to carry.

[0004] In view of this, we propose a portable debugging device based on relay protection. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] A portable debugging device based on relay protection, see Figures 1 to 6, comprising a body 1, a display screen 2 is fixedly installed on the inner side of the body 1, a debugging device 3 is fixedly installed inside the body 1, the display screen 2 is electrically connected to the debugging device 3, a first limiting slide 4 and a second limiting slide 5 are fixedly installed on the inner wall of the body 1, a slide bar 6 is slidably connected inside the first limiting slide 4 and the second limiting slide 5, a slider 7 is fixedly installed on the end of the slide bar 6, a transverse slide 8 is slidably connected inside the slider 7, a rack 9 is fixedly installed on the end of the transverse slide 8, a gear 10 is meshed between the two racks 9, the gear 10 is rotatably connected to a rotating rod 11, one end of the rotating rod 11 is fixedly connected to the inner wall of the body 1, a connecting rod 12 is fixedly installed on the bottom end of the slide bar 6, and the connecting rod 12 is fixedly installed on the bottom end of the slide bar 6. A debugging plugboard 13 is fixedly installed at the end of the connecting rod 12, and a plugboard slot 14 is provided on the side of the body 1. The size and structure of the debugging plugboard 13 and the plugboard slot 14 are matched. An adjustment component 15 is provided at the end of the transverse slide 8. When working, the staff can use the handle 19 to bring the debugging equipment to the site where debugging is required, and use the connecting line to connect the relay protection system to be debugged to the debugging plugboard 13 of the debugging device. The current is transmitted to the debugging device 3 inside the body 1 through the wire 17 of the debugging plugboard 13. The debugging device 3 then transmits the specific parameters to the display screen 2 for display, which is convenient for the staff to refer to and debug. When the debugging plugboard 13 involved in the debugging is damaged, the limit rod 1602 on the rotating mounting frame 1601 is rotated. The limiting effect on the adjusting block 1503 is cancelled. At this time, the adjusting block 1503 is pushed to drive the slide plate 1501 to slide inside the slide groove 1502. At the same time, the slide bar 6 is driven to slide inside the second limiting slide 5. The debugging plug plate 3 slides out from the plug plate groove 14. The slide bar 6 begins to slide from the arc area of ​​the second limiting slide 5 to the straight area. The slider 7 at the end of the slide bar 6 slides inside the transverse slide 8. The rack 9 on one side of the second limiting slide 5 drives the gear 10 meshing with it to rotate. The gear 10 drives the rack 9 on the first limiting slide 4 to move in the opposite direction relative to the rack 9 on the other side of the gear 10, thereby driving the slide bar 6 inside the first limiting slide 4 to move, and continuously pushing the adjusting block 1503 until it drives the second limiting slide 5. When the slide bar 6 of the first limit slide 4 slides to the farthest end of the straight part, and the slide bar 6 in the first limit slide 4 slides to the bottom of the arc part, the debugging plugboard 13 on one side of the first limit slide 4 will slide into the plugboard slot 14, replacing the damaged debugging plugboard 13 to continue working. While pushing the adjustment block 1503, the adjacent adjustment block 1503 will move in the opposite direction until one adjustment block 1503 slides to the rear end of the slide slot 1502, and the other adjustment block 1503 slides to the front end of the slide slot 1502. At this time, the limit rod 1602 on the mounting frame 1601 is rotated to make it contact with the mounting frame 1601 on the other side of the slide slot 1502, and the front end adjustment block 1503 is limited, thereby preventing the adjustment plugboard 13 from sliding out of the plugboard slot 14.The adjustment assembly 15 includes a slide plate 1501, a slide groove 1502 and an adjustment block 1503. The slide plate 1501 is fixedly installed at the end of the transverse slide 8. The slide groove 1502 is symmetrically arranged on the upper surface of the body 1. The slide plate 1501 is slidably connected to the inside of the slide groove 1502 and protrudes from the upper surface of the body 1. The adjustment block 1503 is fixedly installed on the top of the slide plate 1501. The two sides of the slide groove 1502 are provided with limit assemblies 16, which push the adjustment block 1503 to drive the slide plate 1501 in the slide groove 1502. The slide bar 6 slides inside the second limit slideway 5, and the debugging plugboard 3 slides out from the plugboard slot 14. The slide bar 6 starts to slide from the arc area of ​​the second limit slideway 5 to the straight area. The slider 7 at the end of the slide bar 6 slides inside the transverse slideway 8. The rack 9 on one side of the second limit slideway 5 drives the gear 10 meshing with it to rotate. The gear 10 drives the rack 9 on the other side of the first limit slideway 4 and the rack 9 on the other side of the gear 10 to move in the opposite direction, thereby driving the slide bar 6 inside the first limit slideway 4 to move.

[0023] Furthermore, the limiting assembly 16 includes a mounting frame 1601 and a limiting rod 1602. The mounting frames 1601 are symmetrically fixedly installed on both sides of the slide slot 1502. The mounting frame 1601 on one side of the slide slot 1502 is internally rotatably connected to the limiting rod 1602. The end of the limiting rod 1602 contacts the mounting frame 1601 on the other side of the slide slot 1502. The limiting rod 1602 on the rotating mounting frame 1601 contacts the mounting frame 1601 on the other side of the slide slot 1502 to limit the front end adjustment block 1503.

[0024] Furthermore, the side of the debugging board 13 is electrically connected to a wire 17, one end of which is electrically connected to the debugging device 3. The wire 17 of the debugging board 13 transmits current to the debugging device 3 inside the body 1, and the debugging device 3 then transmits specific parameters to the display screen 2 for display.

[0025] It is worth noting that rotating plates 18 are symmetrically fixedly installed on the side of the body 1, and a handle 19 is fixedly and rotatably connected between the two rotating plates 18. The staff can use the handle 19 to bring the debugging equipment to the site where debugging is required.

[0026] It is worth noting that the connecting rod 12 is connected to the position between the center point and the edge of the debugging plug board 13 to ensure that the two debugging plug boards 13 cannot be inserted into the plug board slot 14 due to the distance between the first limiting slide 4 and the second limiting slide 5.

[0027] Working principle: During operation, the staff can use the handle 19 to bring the debugging device to the site where debugging is required, use the connecting wire to connect the relay protection system to be debugged to the debugging plug board 13 of the debugging device, and transmit the current to the debugging device 3 inside the body 1 through the wire 17 of the debugging plug board 13. The debugging device 3 then transmits the specific parameters to the display screen 2 for display, which is convenient for the staff to refer to and debug;

[0028] When the debugging plugboard 13 involved in debugging is damaged, the limiting rod 1602 on the rotating mounting frame 1601 cancels the limiting effect on the adjusting block 1503. At this time, the adjusting block 1503 is pushed to drive the slide plate 1501 to slide inside the slide groove 1502. At the same time, the slide bar 6 is driven to slide inside the second limiting slideway 5. The debugging plugboard 3 slides out from the plugboard groove 14. The slide bar 6 starts to slide from the arc area of ​​the second limiting slideway 5 to the straight area. The slider 7 at the end of the slide bar 6 slides inside the transverse slideway 8. The rack 9 on one side of the second limiting slideway 5 drives the gear 10 meshing therewith to rotate. The gear 10 drives the rack 9 on the first limiting slideway 4 to move in the opposite direction relative to the rack 9 on the other side of the gear 10, thereby driving the slide bar 6 inside the first limiting slideway 4 to move.

[0029] The adjusting block 1503 is continuously pushed until the sliding bar 6 inside the second limiting slide 5 slides to the farthest end of the straight part, and the sliding bar 6 in the first limiting slide 4 slides to the bottom of the arc part. Then, the debugging plugboard 13 on one side of the first limiting slide 4 will slide into the plugboard slot 14, replacing the damaged debugging plugboard 13 to continue working. While pushing the adjusting block 1503, the adjacent adjusting block 1503 will move in the opposite direction until one adjusting block 1503 slides to the rear end of the slide slot 1502, and the other adjusting block 1503 slides to the front end of the slide slot 1502. At this time, the limiting rod 1602 on the rotating mounting frame 1601 contacts the mounting frame 1601 on the other side of the slide slot 1502, and limits the front end adjusting block 1503, thereby preventing the adjusting plugboard 13 from sliding out of the plugboard slot 14, thus completing the entire workflow.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
