Description

Technical Field

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

[0002] Relay protection device test equipment has been widely used in various fields such as line protection, main transformer differential protection, excitation control, etc. Substation integrated automation has become the mainstream, and relay protection device test equipment is an important test tool to ensure the safe and reliable operation of the power system.

[0003] The patent (CN202321894794.1) discloses a relay protection tester, which includes: a relay protection tester body; a protective shell, which is arranged below the relay protection tester body; a placement rack, which is arranged inside the protective shell; a baffle, which is arranged on the protective shell; an operating rod, which is arranged on the protective shell; an adjustment mechanism, which is arranged on the protective shell and the placement rack, and the adjustment mechanism is used to adjust the use position of the placement rack. The relay protection tester provided by the utility model is convenient and safe to transfer when used outdoors, and is convenient to play a safer placement and support role for the relay protection tester body during use.

[0004] The device in the above patent document uses an adjustment mechanism to adjust the use position of the placement rack, so that the placement rack can be used flexibly. However, it does not take into account that when testing power equipment on site, due to limitations of on-site conditions, staff need to test the relay protector test device without a suitable workbench or bracket. In this case, they usually choose to place the test device on the ground for operation. This operation will cause one end of the test line to be suspended in the air, with a height difference from the ground. If the staff does not pay attention in time, the test line may trip, causing the terminal head to separate from the connection hole of the relay protector test device. If the connection hole is separated from the terminal head, the test device and the tested equipment cannot be connected normally, resulting in the inability to accurately transmit the test data, thereby affecting the accuracy of the test results.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 The relay protection device shown comprises a box body 1, a plurality of groups of wiring holes 2 are arranged at equal distances on the top of the box body 1, a clamping mechanism 3 for clamping the wiring head is arranged on the top of the box body 1, stabilizing grooves 4 are arranged on the front, back, left and right sides of the box body 1, and stabilizing mechanisms 5 for stabilizing the box body 1 are arranged inside the four stabilizing grooves 4, and handles 6 are rotatably connected to both sides of the box body 1.

[0027] As attached Figure 2 , Figure 3 and Figure 4The relay protector test device shown in the figure comprises a clamping mechanism 3 comprising a first clamping plate 30 and a second clamping plate 31 respectively arranged on the front and rear sides of the wiring hole 2, the first clamping plate 30 and the second clamping plate 31 are respectively fixedly connected with a first connecting plate 32 and a second connecting plate 33 on the side away from each other, the first connecting plate 32 and the second connecting plate 33 are respectively fixedly connected with a first pushing plate 34 and a second pushing plate 35 at the bottom ends, the first pushing plate 34 and the second pushing plate 35 are respectively fixedly connected with a first moving block 36 and a second moving block 318 at the bottom ends, a guide groove 310 is provided at the top of the box body 1, the front and rear ends of the inner wall of the guide groove 310 are respectively fixedly connected with a first spring 311 and a second spring 319, the other ends of the first spring 311 and the second spring 319 are respectively fixedly connected with the first moving block 36 and the second moving block 318, the first moving block 36 and the second moving block 318 are respectively slidably connected with the guide groove 310 inner wall, one end of the first driving rod 37 and the second driving rod 38 away from the first pushing plate 34 and the second pushing plate 35 passes through the box body 1 and extends to the outside of the box body 1 and is slidably connected to the limiting member 39, the side of the first driving rod 37 and the second driving rod 38 away from each other is fixedly connected to the third spring 312, and the other end of the third spring 312 is fixedly connected to the baffle 313, and the right side of the baffle 313 is fixedly connected to the box body 1, and the design of the first driving rod 37, the second driving rod 38 and the limiting member 39 is to ensure that when multiple wiring heads are inserted into the wiring hole 2, the distance between the first clamping plate 30 and the second clamping plate 31 can pass through the wiring head, and at the same time, the limiting member 39 is directly moved to realize the rapid clamping of the wiring head through the action of the first spring 311, the second spring 319 and the third spring 312, and the first spring 311, the second spring 319 and the third spring 312 are in a compressed state when the clamping mechanism 3 is not started.

[0028] During operation, the staff inserts the wiring head into the wiring hole 2. At this time, the limiting member 39 is moved downward by operating the limiting member 39, so that the limiting member 39 is away from the first driving rod 37 and the second driving rod 38. At this time, the third spring 312, the first spring 311 and the second spring 319 are released, and the first driving rod 37, the second driving rod 38, the first moving block 36 and the second moving block 318 are pushed respectively under the action of the third spring 312, the first spring 311 and the second spring restoring elastic force. At this time, the first driving rod 37 and the first moving block 36 jointly push the first pushing plate 34, and the second driving rod 38 and the second moving block 318 jointly push the second pushing plate 35, and then the first pushing plate 34 and the second pushing plate 35 respectively push the first connecting plate 32 and the second connecting plate 33, and then the first connecting plate 32 and the second connecting plate 33 respectively push the first clamping plate 30 and the second clamping plate 31 to make them close to each other, so as to clamp the wiring head.

[0029] The limit member 39 includes a guide frame 314 fixedly connected to the left side of the box body 1, the outer surface of the guide frame 314 is rotatably connected to the limit plate 315, the guide frame 314 is internally slidably connected to the limit rod 316, the end of the limit rod 316 close to the guide frame 314 is fixedly connected to the limit block 317, the end of the limit rod 316 away from the guide frame 314 is slidably connected to the first drive rod 37 and the second drive rod 38, and the end of the limit rod 316 close to the first drive rod 37 and the second drive rod 38 is designed with matching bevels, and the function of the limit member 39 is to unlock and release the clamping mechanism 3 and the stabilizing mechanism 5 when the limit member 39 moves downward, so as to realize the rapid start of the clamping mechanism 3 and the stabilizing mechanism 5.

[0030] When the limit rod 316 slides to the top, the limit block 317 is located inside the limit plate 315, limiting the limit rod 316 and then the limit rod 316 limits the first drive rod 37 and the second drive rod 38, thereby increasing the distance between the first clamping plate 30 and the second clamping plate 31, making it easier to insert the terminal head into the terminal hole 2. When the terminal head is inserted into the terminal hole 2, the limit rod 316 moves downward and the limit plate 315 is rotated counterclockwise to be parallel to the box body 1. At this time, the limit plate 315 supports the limit block 317, which can limit the upward thrust of the fourth spring 54 in the stabilizing mechanism 5 on the limit rod 316. When the limit rod 316 moves downward, the stabilizing mechanism 5 is activated.

[0031] As attached Figure 5-Figure 8 The relay protector test device shown in the figure, the stabilizing mechanism 5 includes a stabilizing frame 50 rotatably connected to the inner wall of the stabilizing groove 4, the stabilizing frame 50 is rotatably connected to a support rod 51 on one side close to the box body 1, and a support hole 52 matching the support rod 51 is provided on the surface of the stabilizing groove 4, a gusset plate 53 is movably provided at the top position of the stabilizing frame 50, the gusset plate 53 is slidably connected to the inside of the box body 1, a fourth spring 54 is fixedly connected to the bottom end of the gusset plate 53, and the fourth spring 54 is fixedly connected to the box body 1 at one end away from the gusset plate 53, an annular push rod 55 is fixedly connected to the top of the gusset plate 53, and two groups of movable blocks 56 are fixedly connected to the inner side of the annular push rod 55, movable grooves 57 matching the movable blocks 56 are provided on the front and rear sides of the box body 1, and the movable blocks 56 are slidably connected to the inside of the movable grooves 57, and the top of the annular push rod 55 is fixedly connected to the limit rod 316, and the ends of the gusset plate 53 and the stabilizing frame 50 close to each other are provided with mutually matching bevels, and the stabilizing frame 50 is in an inclined state when not started, so it can move under the action of gravity when released.

[0032] When the limit rod 316 moves downward, it pushes the annular push rod 55 to move downward, and then pushes the buckle plate 53 to move downward. At this time, the buckle plate 53 is away from the stabilizing frame 50, and the stabilizing frame 50 is released. The stabilizing frame 50 rotates in the direction away from the box body 1 under the action of gravity. At this time, the user can take out the support rod 51 and buckle it into the support hole 52, which can support the stabilizing frame 50, and then the stabilizing frame 50 plays a stabilizing role on the box body 1, thereby improving the stability of the equipment and preventing it from tipping over. When the equipment is used up, the stabilizing frame 50 rotates to the stabilizing groove 4. In this process, because the buckle plate 53 and the stabilizing frame 50 are close to each other, the buckle plate 53 and the surface of the stabilizing frame 50 slide, and the stabilizing frame 50 pushes the buckle plate 53 to move downward, and the fourth spring 54 is deformed. When the stabilizing frame 50 rotates to the stabilizing groove 4, the stabilizing frame 50 is separated from the buckle plate 53. The fourth spring 54 pushes the buckle plate 53 to move and restricts the movement of the stabilizing frame 50 under the action of restoring the deformation.

[0033] The working principle of the utility model is as follows: during operation, the staff inserts the wiring head into the wiring hole 2, at which time the limit rod 316 is moved downward, and the limit plate 315 is rotated counterclockwise to be parallel to the box body 1. At this time, the limit plate 315 resists the limit block 317, which can limit the upward thrust of the fourth spring 54 on the limit rod 316. At this time, the third spring 312, the first spring 311 and the second spring 319 are released. At this time, the first driving rod 37 and the first moving block 36 jointly push the first propulsion plate 34, the second driving rod 38 and the second moving block 318 jointly push the second propulsion plate 35, and then the first propulsion plate 34 and the second propulsion plate 35 respectively push the first connecting plate 32 and the second connecting plate 33, and then the third spring 312, the first spring 311 and the second spring 319 are released. A connecting plate 32 and a second connecting plate 33 respectively push the first clamping plate 30 and the second clamping plate 31 closer to each other to achieve clamping of the docking terminal. At the same time, when the limit rod 316 moves downward, it pushes the annular push rod 55 to move downward, and then pushes the buckle plate 53 to move. At this time, the buckle plate 53 is away from the stabilizing frame 50, and the stabilizing frame 50 is released. The stabilizing frame 50 is in an inclined state when it is not started. Therefore, when it is released, the stabilizing frame 50 can rotate in the direction away from the box body 1 under the action of gravity. At this time, the user can take out the support rod 51 and buckle it into the support hole 52, which can support the stabilizing frame 50, and then the stabilizing frame 50 can stabilize the box body 1, thereby improving the stability of the equipment and preventing it from tipping over.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
