Description

Technical Field

[0001] The invention relates to the technical field of lightning arrester testing, and more particularly to a lightning arrester testing bracket. Background Art

[0002] Lightning arrester is one of the main equipment of power system. It can effectively limit the overvoltage amplitude of power grid and protect the power transmission and transformation equipment from overvoltage damage, thus ensuring the safe and stable operation of the system. According to the regulations, lightning arrester shall be subjected to insulation, DC reference voltage and other related tests. When conducting the test, it is necessary to fix the lightning arrester with the corresponding lightning arrester test bracket, then ground one end of the lightning arrester, and then connect the high voltage current to the other end of the lightning arrester to conduct insulation, DC reference voltage and other related tests.

[0003] There are two ways to fix the workpiece on the existing workpiece mounting platform: first, an insulating support mechanism is set on the periphery of the workpiece mounting platform, and then a single lightning arrester is directly fixed at the center of the workpiece mounting platform to test the lightning arresters one by one. Such test efficiency is relatively low; second, an insulating support mechanism is set at the center of the workpiece mounting platform, and then multiple lightning arresters are installed on the periphery of the workpiece mounting platform at equal angles, and a conductive block that selectively connects to any lightning arrester is rotatably set at the center. During the test, the conductive block is always in a connected state, but when the conductive block starts to contact with any lightning arrester, the contact area between the conductive block and the lightning arrester is very small, so sparks are easily generated at the contact position, posing a safety hazard.

[0045] Example

[0046] The present invention provides a lightning arrester test bracket, which is used to solve the technical problem of low safety of the lightning arrester test bracket in the prior art. The lightning arrester test bracket comprises a base 1, a top plate 2, a first conductive block 3, a second conductive block 4, an insulating member 5 and a guide member 6, wherein:

[0047] The base 1 is a cylinder having a plurality of first mounting holes 11 at the top thereof, which are evenly distributed on the base 1 along the circumferential direction of the base 1. It should be noted that the base 1 is also provided with a grounding connector for connecting a grounding wire, which further improves the safety of the lightning arrester test bracket provided by the present invention.

[0048] The top plate 2 and the base 1 are spaced apart along the first direction, that is, the top plate 2 is located directly above the base 1 and is arranged parallel to the base 1. The top plate 2 has a plurality of second mounting holes 21, and the plurality of second mounting holes 21 are arranged in a one-to-one correspondence with the plurality of first mounting holes 11. The first mounting holes 11 and the second mounting holes 21 are respectively used to install the two ends of the lightning arrester 40. During installation, the grounding end of the lightning arrester 40 is installed in the first mounting hole 11 on the base 1, and the pressurizing end of the lightning arrester 40 is installed in the second mounting hole 21 on the top plate 2.

[0049] One end of the first conductive block 3 is rotatably installed at the center of the top plate 2. The rotation axis of the first conductive block 3 is the straight line where the center of the top plate 2 is located. The other end of the first conductive block 3 extends toward the edge of the top plate 2. It should be noted that the first conductive block 3 is provided with a high-voltage connector for connecting to the output end of the high-voltage generator. In this way, the rotatably installed first conductive block 3 can be connected to the pressurized end of any lightning arrester 40 on the top plate 2 without the need for repeated wiring.

[0050] There are multiple second conductive blocks 4, and one end of the multiple second conductive blocks 4 can be slidably installed on the top plate 2 along the first direction, and the other end extends toward the center of the top plate 2 and is arranged one by one corresponding to the multiple second mounting holes 21. When the lightning arrester 40 is installed on the base 1 and the top plate 2, the second conductive block 4 is connected to the pressurized end of the lightning arrester 40.

[0051] One end of the insulating member 5 is rotatably and slidably installed in the first direction at the center of the top plate 2 , and the projection of the first conductive block 3 in the first direction coincides with the projection of the insulating member 5 in the first direction.

[0052] There are multiple guide members 6, all of which are installed on the top plate 2 and are arranged one by one corresponding to the multiple second conductive blocks 4. The guide members 6 are used to guide the insulating member 5 to drive the second conductive blocks 4 to move in a direction close to the first conductive block 3 when the insulating member 5 rotates. Through the setting of the guide members 6, the insulating member 5 is guided to gradually move in a direction close to the first conductive block 3 while rotating. When the first conductive block 3 rotates to approach the second conductive block 4, the end of the second conductive block 4 extending toward the center of the top plate 2 gradually overlaps the top of the insulating member 5, so that the second conductive block 4 gradually moves in a direction close to the first conductive block 3 until the first conductive block 3 fits with the second conductive block 4, and the first conductive block 3 and the insulating plate 10 are in contact with each other. Stop rotating, thereby connecting the first conductive block 3 and the second conductive block 4, that is, connecting the output end of the high-voltage generator and the pressurized end of the lightning arrester 40. After the connection, the test can be started. After the test, continue to drive the first conductive block 3 and the insulating member 5, and the contact area between the insulating member 5 and the guide member 6 gradually decreases until the insulating member 5 and the guide member 6 are completely separated, and the force supporting the insulating member 5 disappears. The insulating member 5 moves away from the first conductive block 3 under the action of gravity, and at the same time, the second conductive block 4 moves away from the first conductive block 3, that is, the second conductive block 4 is separated from the first conductive block 3. In this way, no spark will be generated between the first conductive block 3 and the second conductive block 4 due to the gradual reduction of the contact area.

[0053] Through the above structure, when it is necessary to test the lightning arrester 40, the lightning arrester test bracket provided by the present invention is first placed on a flat ground, and then the grounding ends of multiple lightning arresters 40 are installed in the first mounting holes 11 on the base 1, and the pressurized ends of multiple lightning arresters 40 are installed in the second mounting holes 21 on the top plate 2, and the pressurized ends of the lightning arresters 40 are connected to the driving assembly through the top plate 2, and then the grounding wire and the high-voltage generator output wire are respectively connected to the base 1 and the first conductive block 3, and then the first conductive block 3 and the insulating member 5 are driven to rotate synchronously on the top plate 2 at the same time, that is, the first conductive block 3 and the insulating member 5 are moved toward any second conductive block 3. The insulating member 5 gradually moves in the direction of the guide member 6 when the rotation starts, until the insulating member 5 overlaps the guide member 6. The insulating member 5 continues to rotate. Under the action of the guide member 6, the insulating member 5 gradually moves in the direction of the first conductive block 3 while rotating. When the first conductive block 3 and the insulating member 5 are close to the second conductive block 4, the second conductive block 4 overlaps the insulating member 5, so that the second conductive block 4 and the insulating member 5 gradually move in the direction of the second conductive block 4 synchronously until the first conductive block 3 fits the second conductive block 4. The first conductive block 3 and the insulating member 5 stop rotating, and the operation of the instrument starts. Connecting the high-voltage generator The output line is connected to the first conductive block 3, thereby conducting the pressurized end of the lightning arrester 40 and the high-voltage generator, and a test is carried out. After the test is completed, the first conductive block 3 and the insulating member 5 are driven to rotate again, so that the insulating member 5 is separated from the guide member 6. The insulating member 5 moves in a direction away from the first conductive block 3 under the action of gravity, and the second conductive block 4 overlapped on the insulating member 5 moves in a direction away from the first conductive block 3 synchronously, so that the first conductive block 3 is separated from the second conductive block 4 and disconnected. The first conductive block 3 and the insulating member 5 continue to rotate until they rotate to the next guide member 6. The insulating member 5 and the second conductive block 4 are moved closer to the guide member 6 again under the action of the guide member 6. The first conductive block 3 is moved in the direction of a conductive block 3 until the second conductive block 4 is in contact with the first conductive block 3 for the second time. In this way, the pressurized end of the lightning arrester 40 and the high-voltage generator are connected again, and the test is carried out again. The above steps are repeated until each lightning arrester 40 completes the test, and then the output line of the high-voltage generator is disconnected from the first conductive block 3, and each lightning arrester 40 is discharged again and taken out. In this way, through the arrangement of the insulating member 5 and the guide member 6, the first conductive block 3 and the second conductive block 4 can quickly contact and separate when they are in contact or separated, thereby reducing the probability of spark generation, thereby making the lightning arrester test bracket provided by the present invention safer.

[0054] An optional implementation of this embodiment is as follows: the guide member 6 includes a wedge block 61 and a rectangular block 62, wherein:

[0055] The wedge block 61 is arc-shaped, and the longitudinal section of the wedge block 61 is rectangular, and the longitudinal cross-sectional area of ​​the wedge block 61 gradually increases from one end to the other end, that is, the top surface of the wedge block 61 gradually tilts upward from one end to the other end, so that when the insulating member 5 rotates, it gradually approaches the small diameter end of the wedge block 61, and when the end of the insulating member 5 away from the center of the top plate 2 overlaps the wedge block 61, the insulating member 5 slides on the top surface of the wedge block 61, so that the insulating member 5 moves in a direction gradually approaching the first conductive block 3.

[0056] The rectangular block 62 is also arc-shaped, and the rectangular block 62 is fixedly installed on the large diameter end of the wedge block 61. The length of the rectangular block 62 in the first direction is equal to the length of the large diameter end of the wedge block 61 in the first direction. It should be noted that the second conductive block 4 is located directly above the rectangular block 62. In this way, when the insulating member 5 slides onto the rectangular block 62, the first conductive block 3 and the second conductive block 4 are in a fitted state. Through the setting of the rectangular block 62, the insulating member 5 is supported more firmly, avoiding the unstable fit between the first conductive block 3 and the second conductive block 4, thereby preventing the generation of sparks.

[0057] An optional implementation of the present embodiment is as follows: the wedge block 61 of any guide member 6 is adjacent to the rectangular block 62 of the adjacent guide member 6, so that when the test of any lightning arrester 40 is completed, after driving the first conductive block 3 and the insulating member 5 to continue rotating, the insulating member 5 will fall off the rectangular block 62, thereby separating the first conductive block 3 from the second conductive block 4.

[0058] An optional implementation of this embodiment is as follows: it also includes a rotating shaft 7 and a sliding block, wherein:

[0059] One end of the rotating shaft 7 is rotatably mounted on the top plate 2, the first conductive block 3 is fixedly mounted on the other end of the rotating shaft 7, and one end of the insulating member 5 is rotatably and slidably mounted along the first direction on the other end of the rotating shaft 7. In this way, through the setting of the rotating shaft 7, when the rotating shaft 7 rotates, the first conductive block 3 and the insulating member 5 are driven to rotate synchronously.

[0060] Optionally, a circular hole adapted to the rotating shaft 7 is opened at the top of the insulating part 5, a protrusion is provided on the inner wall of the circular hole, and a slideway adapted to the protrusion is opened on the outer wall of the rotating shaft 7, and the protrusion is slidably inserted in the slideway. In this way, through the cooperation of the slideway and the protrusion, not only can the insulating part 5 move up and down on the rotating shaft 7, but also the downward sliding length of the insulating part 5 can be limited, thereby preventing the insulating part 5 from falling below the small diameter end of the guide part 6, which makes the insulating part 5 unable to overlap the guide part 6.

[0061] Optionally, it further comprises a first rod 8, a first elastic member 81 and a second rod 82, wherein:

[0062] One end of the first rod 8 is installed on a side of the insulating member 5 close to the guide member 6 .

[0063] The other end of the first rod 8 is provided with a mounting groove, and one end of the first elastic member 81 is fixedly mounted in the mounting groove.

[0064] One end of the second rod 82 is slidably installed in the first rod 8, and the other end of the first elastic member 81 is fixedly installed on the end of the second rod 82 extending into the installation groove. In this way, through the setting of the first elastic member 81, the length of the second rod 82 extending from the first rod 8 is adjustable. When the second rod 82 is worn due to friction between the guide member 6, it can be compensated by the first elastic member 81, so as to avoid the first conductive block 3 and the second conductive block 4 from being unable to fully fit together when the second rod 82 reaches the top of the rectangular block 62, thereby causing sparks to be generated between the first conductive block 3 and the second conductive block 4.

[0065] An optional implementation of this embodiment is as follows: it also includes a lifting assembly 9, the number of which is multiple, and the multiple lifting assemblies 9 are respectively installed between the multiple first conductive blocks 3 and the top plate 2. The lifting assembly 9 includes a conductive rod 91 and a second elastic member 92, wherein:

[0066] The conductive rod 91 is installed in the second mounting hole 21, one end of the second conductive block 4 is slidably installed on the conductive rod 91, and the other end of the second conductive block 4 extends toward the center of the top plate 2. In this way, through the setting of the conductive rod 91, the pressurized end of the lightning arrester 40 is extended to the outside of the top plate 2, which is more convenient to connect the first conductive block 3 with the pressurized end of the lightning arrester 40.

[0067] One end of the second elastic member 92 is connected to the top plate 2, and the other end is connected to the second conductive block 4. Thus, through the setting of the second elastic member 92, when the second conductive block 4 is pushed upward by the insulating member 5, the second elastic member 92 is stretched. When the force pushing the second conductive block 4 disappears, the second elastic member 92 recovers, thereby driving the second conductive block 4 to move downward. Thus, it is prevented that the second conductive block 4 cannot fall due to its own gravity, thereby causing the connection between the first conductive block 3 and the second conductive block 4 to be unstable and generate sparks.

[0068] Optionally, it also includes an insulating plate 10, one end of which is slidably mounted on the conductive rod 91, and the first conductive block 3 is mounted on the top of the insulating plate 10, and one end of the second elastic member 92 is connected to the insulating plate 10. In this way, through the setting of the insulating plate 10, high voltage can be prevented from damaging the second elastic member 92, and high voltage can be prevented from being transmitted to the top plate 2 through the second elastic member 92.

[0069] Optionally, the longitudinal section of the insulating plate 10 gradually increases from one end of the insulating plate 10 close to the wedge block 61 to one end of the insulating plate 10 away from the wedge block 61 , so that it is easier to overlap the insulating plate 10 onto the insulating member 5 .

[0070] It also includes a slider 20. A through hole adapted to the conductive rod 91 is opened on the insulating plate 10. The slider 20 is installed on the inner wall of the through hole. A slide groove 911 adapted to the slider 20 is opened on the outer wall of the conductive rod 91. The slider 20 is slidably inserted in the slide groove 911. In this way, the cooperation between the slider 20 and the slide groove 911 can prevent the insulating plate 10 from rotating on the conductive rod 91, and at the same time prevent the insulating plate 10 from descending too low. When the insulating member 5 rotates to the insulating plate 10, the insulating plate 10 cannot overlap the top of the insulating plate 10.

[0071] An optional implementation of this embodiment is as follows: it also includes a driving member, one end of which is installed at the center of the base 1 and the other end is connected to the rotating shaft 7. In this way, the arrangement of the driving member makes it easier to drive the rotating shaft 7 to rotate.

[0072] Optionally, the driving member is an electric motor 30. Specifically, a placement groove is opened at the center of the top of the base 1, and the motor 30 is placed in the placement groove, and an insulating layer is provided in the placement groove. It should be noted that the motor 30 is electrically connected to the power supply through a line, and a switch for controlling the on and off of the line is provided on the line. The switch can be a wired switch or a wireless switch. Selecting the electric motor 30 as the power source can provide stable rotational power and is easy to control.

[0073] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
