Description

Technical Field

[0001] The present application relates to the technical field of power equipment detection, and in particular to a power safety equipment detection platform. Background Art

[0002] During the inspection and maintenance of power system equipment, various power safety devices are required to enhance the protection of operators and power equipment. Power safety devices include insulating clamps, insulating operating rods, grounding wire operating rods, electroscope rods, phase detectors, etc.

[0003] Among them, insulating operating rods, also known as insulating rods, are commonly used for knife switch operation and insulator testing. Insulating rods typically consist of an insulating portion, a metal portion, and a handle. Before commissioning, insulating rods require a withstand voltage insulation test. This test involves mounting the rod on an insulation testing platform, connecting one end of the test section to high voltage and the other end to ground. Different levels of high voltage are applied to the metal portion of the rod for a period of time. The rod's outer surface is then inspected for obvious discharge marks, abnormal heating, or insulation damage.

[0004] Generally speaking, when testing insulating rods using a testing platform, the test lengths of insulating rods corresponding to different voltage levels are different according to the design requirements of relevant specifications. For example, the 10KV voltage level requires that the effective test length of the insulating rod must not be less than 0.7m, and the 35KV voltage level requires that the effective test length of the insulating rod must not be less than 1.87m. Therefore, after replacing the insulating rod, it is necessary to adjust the distance between the high-voltage end and the grounding end of the testing platform according to the corresponding high-voltage level so that the test section length of the insulating rod matches the voltage level. In actual operation, this means that the distance between the high-voltage end and the grounding end of the testing platform needs to be calibrated, which reduces the efficiency of the insulating rod withstand voltage test. Summary of the Invention

[0005] In order to improve the working efficiency of insulating rod withstand voltage testing, the present application provides an electric safety device testing platform.

[0006] This application provides an electric safety device detection platform that adopts the following technical solutions:

[0007] An electric safety device detection platform includes a support system, an adjustment rod, a mounting plate, and a clamping plate;

[0008] The support system is used to support the adjustment rod, the mounting plate and the clamping plate;

[0009] The mounting plate and the clamping plate are used to fix the two ends of the insulating rod respectively, and the current is input through the clamping plate and output to ground by the mounting plate;

[0010] The adjusting rod is provided with a plurality of installation stations along its length direction. The installation plate can be installed at different installation stations, and each installation station corresponds to a different voltage level.

[0011] Through the above technical solution, when the operator needs to perform a withstand voltage test on the insulating rod, he first installs the mounting plate at the corresponding installation position on the adjusting rod according to the voltage level corresponding to the insulating rod to be subjected to the withstand voltage test. For example, if the insulating rod is suitable for equipment operation of a 35KV line, the mounting plate is installed at the installation position corresponding to 35KV on the adjusting rod.

[0012] Then, the ends of the insulating rod are mounted on the clamping plate and the mounting plate, respectively, securing the rod. Next, the current generating device is connected to the clamping plate, and the mounting plate is grounded. This allows the current from the current generating device to be conducted to the ground along the clamping plate, the insulating rod, and the mounting plate, given the weak conductivity of the insulating rod.

[0013] During the above-mentioned withstand voltage test of the insulating rod, the operator only needs to install it on the corresponding installation station according to the corresponding voltage level of the insulating rod. Since there is no need to measure the distance between the clamping plate and the mounting plate, that is, there is no need to measure the distance between the high-voltage end and the grounding end, the work efficiency of the withstand voltage test of the insulating rod is improved.

[0014] In a preferred example, the present application can be further configured as follows: a fixing ring for fixing the insulating rod is rotatably installed on the mounting plate, a limiting groove for placing the insulating rod is opened on the mounting plate, and a linkage device is provided on the fixing ring, and the linkage device is used to drive the fixing ring to fix the insulating rod.

[0015] Through the above technical solution, after the operator places the insulating rod in the limit groove on the mounting plate, the linkage device drives the fixing ring to rotate onto the insulating rod. Under the fixing action of the fixing ring, the insulating rod is fixed, which reduces the possibility of movement of the insulating rod during the voltage withstand test.

[0016] In a preferred example, the present application can be further configured as follows: the linkage device includes a baffle, a through slot for the baffle to rotate is opened in the mounting plate, the through slot and the limit slot are connected to each other, the baffle in a horizontal state and the top inner wall of the through slot are abutted and matched, the baffle and the insulating rod are abutted and matched, the baffle is arranged on the fixing ring, and when the insulating rod is placed in the limit slot, the insulating rod pushes the fixing ring to rotate through the baffle, thereby completing the fixation of the insulating rod to the fixing ring.

[0017] With the above technical solution, before the insulating rod is placed in the upper limit slot of the mounting plate, the baffle is horizontal and the retaining ring is vertical, that is, the baffle abuts the top inner wall of the through slot. As the operator places the insulating rod into the upper limit slot of the mounting plate, after the insulating rod and baffle come into contact, the insulating rod continues to move downward. Under the influence of the insulating rod's gravity, the insulating rod pushes the baffle downward, and simultaneously, the baffle drives the retaining ring to rotate toward the insulating rod, causing it to buckle against the outer wall of the insulating rod, thus securing the insulating rod. At this point, the baffle is vertical and the retaining ring is horizontal.

[0018] After completing the voltage test, the operator needs to remove the insulating rod from the mounting plate. The operator only needs to pull the insulating rod upwards. The insulating rod pushes the fixing ring to rotate, and the baffle rotates with the fixing ring, so that the fixing ring rotates to a vertical state and the baffle rotates to a horizontal state, and the baffle abuts against the top inner wall of the through groove.

[0019] During the process of fixing and releasing the insulating rod by the fixing ring, the insulating rod only needs to be placed in the limit groove and pulled up to complete the fixing and releasing of the insulating rod. There is no need for the operator to manually operate the fixing ring, thereby further improving the work efficiency of the insulating rod withstand voltage test.

[0020] In a preferred example, the present application can be further configured as follows: the cross section of the fixing ring is semi-circular, and the straight line where the diameter of the fixing ring passes through the axis of rotation of the fixing ring is perpendicular to the baffle.

[0021] Through the above technical solution, since the cross-section of the fixing ring is semi-circular, the fixing ring is in a vertical state, and the straight line where the diameter of the fixing ring passes through the axis of rotation of the fixing ring is perpendicular to the baffle, the center of gravity of the fixing ring deviates from the straight line where the diameter of the fixing ring passes through the axis of rotation of the fixing ring. Therefore, when the operator is pulling the insulating rod upward, after the center of gravity of the fixing ring leaves the vertical line where the axis of rotation of the fixing ring passes, the center of gravity of the fixing ring continues to drop, and the fixing ring can continue to drive the baffle to rotate until the baffle rotates to a horizontal state, thereby making advance preparations for the fixation of the next insulating rod.

[0022] In a preferred example, the present application can be further configured as follows: the weight of the fixing ring is greater than the mass of the baffle.

[0023] Through the above technical solution, since the weight of the fixing ring is greater than the mass of the baffle, on the one hand, when the baffle is in a vertical state, the possibility of the baffle swinging can be reduced, thereby improving the fixing effect of the fixing ring on the insulating rod; on the other hand, when the baffle is in a horizontal state, under the pressure of the fixing ring, the possibility of the baffle rotating downward can be reduced, thereby maintaining the horizontal state of the baffle, so as to prepare in advance for the fixation of the next insulating rod.

[0024] In a preferred example, the present application can be further configured as follows: the support system includes a plurality of outer rods and a plurality of inner rods, and the plurality of outer rods and the plurality of inner rods are arranged in a one-to-one correspondence, the adjusting rod is installed on the inner rod, and the inner rod is slidably installed in the corresponding outer rod, and the outer rod is provided with a bolt for fixing the corresponding inner rod.

[0025] Through the above technical solution, since different voltages have different requirements for the test height of the insulating rod, before starting the voltage withstand test of the insulating rod, the inner rod is pulled out upward or outward, and the height of the adjusting rod and the clamping plate are adjusted so that the height of the insulating rod tested subsequently meets the voltage requirements for the test height, and the inner rod is fixed with bolts to maintain the installation height of the insulating rod.

[0026] In a preferred example, the present application can be further configured as follows: a universal wheel is installed at the bottom end of the outer rod.

[0027] With the above technical solution, since universal wheels are installed at the bottom end of the outer rod, it is convenient for operators to move the detection platform.

[0028] In a preferred example, the present application can be further configured as follows: the clamping plate includes an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are used to clamp the insulating rod, and the upper clamping plate and the lower clamping plate are connected by bolts.

[0029] Through the above technical solution, when the operator needs to fix the insulating rod through the clamping plate, the insulating rod is placed between the upper clamping plate and the lower clamping plate, and the upper clamping plate and the lower clamping plate are closed, and the upper clamping plate and the lower clamping plate are connected by bolts to complete the fixation of the insulating rod by the clamping plate.

[0030] In summary, this application has the following beneficial technical effects:

[0031] 1. During the withstand voltage test of the insulating rod, the operator only needs to install it at the corresponding installation position according to the corresponding voltage level of the insulating rod. Since there is no need to measure the distance between the clamping plate and the mounting plate, that is, there is no need to measure the distance between the high-voltage end and the grounding end, the efficiency of the withstand voltage test of the insulating rod is improved;

[0032] 2. When the fixing ring is used to fix or release the insulating rod, the insulating rod only needs to be placed in the limit groove and pulled up to complete the fixing or release of the insulating rod. There is no need for the operator to manually operate the fixing ring, thus further improving the efficiency of the insulating rod withstand voltage test. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0041] An embodiment of the present application discloses a power safety device detection platform.

[0042] Refer to the attached Figure 1 As shown, an electric safety device detection platform includes a support system 1, two adjustment rods 2, a mounting plate 3 and a clamping plate 4.

[0043] Refer to the attached Figure 1 As shown, the metal end of the insulating rod 5 is fixed by the clamping plate 4, and the other end of the insulating rod 5 is fixed by the mounting plate 3.

[0044] Refer to the attached Figure 1As shown, the two adjusting rods 2 are arranged parallel to each other, and the clamping plate 4 and the mounting plate 3 are both arranged on the opposite inner sides of the two adjusting rods 2. Several mounting stations 21 are arranged on the adjusting rod 2 along its length direction. The mounting plate 3 can be installed on different mounting stations 21. The distance between each mounting station and the clamping plate 4 on the same adjusting rod 2 is different. Each mounting station 21 corresponds to a different voltage level, that is, the voltage level corresponding to the mounting station 21 on the same adjusting rod 2 from near to far from the clamping plate 4 gradually increases; both ends of the clamping plate 4 and both ends of the mounting plate 3 are installed on different adjusting rods 2, the clamping plate 4 can be connected to the current generating equipment, and the mounting plate 3 can be grounded. The current is input through the clamping plate 4 and output by the mounting plate 3 to the ground.

[0045] Refer to the attached Figure 1 As shown, the support system 1 is used to support the adjustment rod 2 , the mounting plate 3 and the clamping plate 4 .

[0046] When the operator needs to perform a withstand voltage test on the insulating rod 5, he first installs the mounting plate 3 at the corresponding installation position 21 on the adjusting rod 2 according to the voltage level corresponding to the insulating rod 5 to be subjected to the withstand voltage test. For example, if the insulating rod 5 is suitable for equipment operation of a 35KV line, the mounting plate 3 is installed at the installation position 21 corresponding to 35KV on the adjusting rod 2.

[0047] Then, the two ends of the insulating rod 5 are mounted on the clamping plate 4 and the mounting plate 3, respectively, to secure the insulating rod 5. Next, the current generating device is connected to the clamping plate 4, and the mounting plate 3 is grounded. This allows the current from the current generating device to be conducted to the ground along the clamping plate 4, the insulating rod 5, and the mounting plate 3, given the weak conductivity of the insulating rod 5.

[0048] During the above-mentioned withstand voltage test of the insulating rod 5, the operator only needs to install it on the corresponding installation station 21 according to the voltage level corresponding to the insulating rod 5. Since there is no need to clamp the distance between the plate 4 and the mounting plate 3, that is, there is no need to measure the distance between the high-voltage end and the ground end, the working efficiency of the withstand voltage test of the insulating rod 5 is improved.

[0049] Refer to the attached Figure 1 As shown, the support system 1 includes four inner rods 11 and four outer rods 12. The four inner rods 11 and the four outer rods 12 are vertically arranged in a one-to-one correspondence. The inner rods 11 are slidably arranged in the corresponding outer rods 12. The two ends of each adjustment rod 2 are respectively mounted on the top of different inner rods 11. The outer rods 12 are equipped with bolts for fixing the inner rods 11. The bottom end of each outer rod 12 is equipped with a universal wheel 121 to facilitate the movement of the device.

[0050] When conducting insulation tests, it's crucial to maintain a safe distance between the tester and live equipment to prevent electric shock. This distance is often dependent on factors such as the equipment voltage level, the test environment, and the test height. Air density can change with altitude, affecting electric field distribution and insulation performance. Therefore, when conducting insulation tests, it's important to adjust the safe distance and test height to ensure safety.

[0051] Since different voltages have different requirements for the test height of the insulating rod 5, before starting the withstand voltage test of the insulating rod 5, first pull out the inner rod 11 upward or pull out the inner rod 11, adjust the height of the adjusting rod 2 and the clamping plate 4, so that the height of the insulating rod 5 tested subsequently meets the voltage requirements for the test height, and fix the inner rod 11 with bolts to maintain the installation height of the insulating rod 5.

[0052] Refer to the attached Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a fixing ring 6 is rotatably mounted on the mounting plate 3 for fixing the insulating rod 5, and the cross-section of the fixing ring 6 is semi-circular; a limiting groove 31 is provided on the mounting plate 3 for placing the insulating rod 5; a linkage device is provided on the fixing ring 6, which is used to drive the fixing ring 6 to fix the insulating rod 5.

[0053] Refer to the attached Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the linkage device includes a baffle 32, and a through slot 33 is opened in the mounting plate 3 for the baffle 32 to rotate. The through slot 33 and the limiting slot 31 are connected to each other. The baffle 32 in the horizontal state abuts and fits with the top inner wall of the through slot 33, and the baffle 32 and the insulating rod 5 abut and fit. The baffle 32 and the fixing ring 6 can be integrally formed and can also be fixedly connected. When the insulating rod 5 is placed in the limiting slot 31, the insulating rod 5 pushes the fixing ring 6 to rotate through the baffle 32, thereby completing the fixation of the fixing ring 6 to the insulating rod 5.

[0054] Before the insulating rod 5 is placed in the upper limit groove 31 on the mounting plate 3 , the baffle 32 is in a horizontal state and the fixing ring 6 is in a vertical state, that is, the baffle 32 abuts against the top inner wall of the through groove 33 .

[0055] When the operator places the insulating rod 5 into the upper limit groove 31 of the mounting plate 3, after the insulating rod 5 and the baffle 32 come into contact, the operator applies appropriate downward pressure to the insulating rod 5 under the action of the weight of the insulating rod 5. The insulating rod 5 pushes the baffle 32 downward to rotate. At the same time, the baffle 32 drives the fixing ring 6 to rotate toward the insulating rod 5, causing the fixing ring 6 to buckle against the outer wall of the insulating rod 5, thus securing the insulating rod 5. At this point, the baffle 32 is in a vertical position and the fixing ring 6 is in a horizontal position.

[0056] After completing the voltage test, the operator needs to remove the insulating rod 5 from the mounting plate 3. The operator only needs to pull the insulating rod 5 upwards, and the insulating rod 5 pushes the fixing ring 6 to rotate, and the baffle 32 rotates with the fixing ring 6, so that the fixing ring 6 rotates to a vertical state and the baffle 32 rotates to a horizontal state, and the baffle 32 abuts against the top inner wall of the through groove 33.

[0057] In the process of fixing and releasing the insulating rod 5 by the fixing ring 6, it is only necessary to place the insulating rod 5 into the limiting groove 31 and pull up the insulating rod 5 to complete the fixing and releasing of the insulating rod 5. There is no need for the operator to manually operate the fixing ring 6, thereby further improving the work efficiency of the withstand voltage test of the insulating rod 5.

[0058] Refer to the attached Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the straight line where the diameter of the fixing ring 6 passes through the rotation axis of the fixing ring 6 is perpendicular to the baffle 32 , and the weight of the fixing ring 6 is greater than the mass of the baffle 32 .

[0059] Since the cross-section of the fixing ring 6 is semi-circular, the fixing ring 6 is in a vertical state, and the straight line where the diameter of the fixing ring 6 passes through the rotation axis of the fixing ring 6 is perpendicular to the baffle 32, the center of gravity of the fixing ring 6 deviates from the straight line where the diameter of the fixing ring 6 passes through the rotation axis of the fixing ring 6. Therefore, when the operator is pulling the insulating rod 5 upward, after the center of gravity of the fixing ring 6 leaves the vertical line passed by the rotation axis of the fixing ring 6, the center of gravity of the fixing ring 6 continues to drop, and the fixing ring 6 can continue to drive the baffle 32 to rotate until the baffle 32 rotates to a horizontal state, thereby preparing in advance for the fixation of the next insulating rod 5.

[0060] In addition, since the weight of the fixing ring 6 is greater than the mass of the baffle 32, on the one hand, when the baffle 32 is in a vertical state, the possibility of the baffle 32 swinging can be reduced, thereby improving the fixing effect of the fixing ring 6 on the insulating rod 5; on the other hand, when the baffle 32 is in a horizontal state, under the pressure of the fixing ring 6, the possibility of the baffle 32 rotating downward can be reduced, thereby maintaining the horizontal state of the baffle 32, so as to make advance preparations for the fixation of the next insulating rod 5.

[0061] Refer to the attached Figure 1 and attached Figure 5As shown, the clamping plate 4 includes an upper clamping plate 41 and a lower clamping plate 42. The upper clamping plate is located directly above the lower clamping plate 42. The upper clamping plate 41 and the lower clamping plate 42 are used to clamp the insulating rod 5. The upper clamping plate 41 and the lower clamping plate 42 are connected by bolts. When the operator needs to secure the insulating rod 5 using the clamping plate 4, the insulating rod 5 is placed between the upper clamping plate and the lower clamping plate 42, and the upper clamping plate and the lower clamping plate 42 are closed. The upper clamping plate 41 and the lower clamping plate 42 are then connected with bolts to complete the securing of the clamping plate 4 to the insulating rod 5.

[0062] The implementation principle of this embodiment is as follows: during the withstand voltage test of the insulating rod 5, the operator only needs to install it on the corresponding installation station 21 according to the voltage level corresponding to the insulating rod 5. Since there is no need to maintain a distance between the clamping plate 4 and the mounting plate 3, that is, there is no need to measure the distance between the high-voltage end and the ground end, the working efficiency of the withstand voltage test of the insulating rod 5 is improved.

[0063] Moreover, in the process of fixing the insulating rod 5 and releasing the fixing of the insulating rod 5 by the fixing ring 6, it is only necessary to place the insulating rod 5 into the limiting groove 31 and pull up the insulating rod 5 to complete the fixing and releasing of the insulating rod 5. There is no need for the operator to manually operate the fixing ring 6, thereby further improving the work efficiency of the withstand voltage test of the insulating rod 5.

[0064] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application in turn. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
