Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage electrical testing, and more particularly to a high-voltage electrical testing line support tool and a high-voltage electrical testing device comprising the high-voltage electrical testing line support tool. Background Art

[0002] Conducting electrical tests on high-voltage equipment in substations can accurately understand the health of the equipment, allowing for the development of appropriate inspection, replacement, and operation and maintenance strategies, which is of great significance for ensuring the safe and stable operation of the power system. In high-voltage electrical tests, the equipment is wired using an insulating rod. First, the operator needs to connect the test line to the metal hook at the top of the insulating rod. Then, the metal hook is hooked to the high-voltage equipment wiring bolts, equalizing rings, and other wiring locations to connect the test line to the equipment wiring location. In high-voltage electrical tests, to ensure pressurization safety and reduce the impact of capacitance on the accuracy of test results, the angle between the test line and the equipment body is required to be 90 degrees, that is, the test line is connected vertically to the equipment.

[0003] Conventional technology typically involves assigning a tester to hold an insulating rod and lift the test wire perpendicular to the equipment during high-voltage electrical testing. This approach requires an additional operator to laboriously lift the rod throughout the test. Furthermore, during high-voltage tests like the arrester DC leakage test, the voltage applied to the test wire can reach hundreds of thousands of volts, posing a significant risk of injury to the tester from induced electrocution and the possibility of the lifted test wire falling.

[0004] In summary, how to make the test line support operation in high-voltage electrical testing safer, more convenient and efficient, so as to improve the safety and efficiency of high-voltage electrical testing, is a problem that needs to be urgently solved by technical personnel in this field. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a high-voltage electrical test line support tool, which can make the test line support operation in high-voltage electrical testing safer, more convenient and efficient, so as to improve the safety and efficiency of high-voltage electrical testing.

[0006] Another object of the present invention is to provide a high-voltage electrical test device comprising the above-mentioned high-voltage electrical test line supporting tool.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A high-voltage electrical test line support tool, comprising:

[0009] A clamp, which is used to be detachably sleeved on the outer periphery of the insulating rod;

[0010] A support arm, which is provided on one side of the clamp and can be deformed by force;

[0011] A limiting ring is provided at the end of the support arm and is used to pass a high-voltage test line.

[0012] In one embodiment, the clamp includes a first clip and a second clip arranged in cooperation with the first clip, the first clip and the second clip are both provided with an arc groove for accommodating the insulating rod, the first end of the first clip and the first end of the second clip are hinged, and the second end of the first clip and the second end of the second clip are correspondingly provided with mounting holes, and the mounting holes are used to pass through the locking member.

[0015] In one embodiment, the end of the second rod is provided with a Velcro strap.

[0016] In one embodiment, the support arm includes a thin-walled aluminum alloy tube provided on one side of the clamp and a wrapping layer wrapped around the outer periphery of the thin-walled aluminum alloy tube, and the wrapping layer includes a silicone layer or a rubber layer.

[0019] In one embodiment, the limiting ring includes an insulating ring.

[0020] A high-voltage electrical test device comprises the high-voltage electrical test line supporting tool described in any one of the above items.

[0021] When using the high-voltage electrical test line support tool provided by the present invention, first, the tester puts the clamp on the outer periphery of the insulating rod to clamp and fix the insulating rod with the clamp. Then, according to the angle at which the insulating rod is to be hung, bend the support arm to a suitable position so that the hung support arm is perpendicular to the equipment. After that, pass the high-voltage test line through the limit ring and connect it to the metal hook on the top of the insulating rod. Finally, hang the insulating rod on the equipment in the expected manner. At this time, the angle between the high-voltage test line and the equipment is about 90°. By using this device, there is no need for additional testers to perform the wire picking operation (the wire picking operation is the tester holding the insulating rod, picking up the high-voltage test line, and making the high-voltage test line perpendicular to the equipment).

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The core of the present invention is to provide a high-voltage electrical test line support tool that can make the test line support operation during high-voltage electrical testing safer, more convenient and more efficient, thereby improving the safety and efficiency of high-voltage electrical testing. Another core of the present invention is to provide a high-voltage electrical test device that includes the high-voltage electrical test line support tool.

[0031] Please refer to Figure 1 and Figure 2 This specific embodiment provides a high-voltage electrical test line support tool, including:

[0032] A clamp 9, which is used to be detachably sleeved on the outer periphery of the insulating rod;

[0033] A support arm 6 is provided on one side of the clamp 9 and can be deformed by force;

[0034] The limiting ring 7 is provided at the end of the supporting arm 6 and is used to pass the high-voltage test line.

[0035] It should be noted that the detachable attachment of the clamp 9 to the insulating rod means that when a high-voltage electrical test is required, the operator can open the clamp 9, attach the clamp 9 to the insulating rod, and then clamp the insulating rod with the clamp 9. When the high-voltage electrical test is no longer required, the operator can open the clamp 9 again and remove the clamp 9 from the insulating rod. The stress-deformable support arm 6 means that the support arm 6 can appropriately deform when subjected to stress, while still maintaining a certain strength to effectively support the high-voltage test line.

[0036] During actual use, the shape, structure, size, material, etc. of the clamp 9, the support arm 6 and the limiting ring 7 can be determined according to actual conditions and actual needs.

[0037] When using the high-voltage electrical test line support tool provided by the present invention, first, the tester puts the clamp 9 on the outer periphery of the insulating rod to clamp and fix the insulating rod with the clamp 9. Then, according to the angle at which the insulating rod is to be hung, bend the support arm 6 to a suitable position so that the hung support arm 6 is perpendicular to the equipment. After that, pass the high-voltage test line through the limiting ring 7 and connect it to the metal hook at the top of the insulating rod. Finally, hang the insulating rod on the equipment in the expected manner. At this time, the angle between the high-voltage test line and the equipment is about 90°. By using this device, there is no need for additional testers to perform the wire picking operation (the wire picking operation is the tester holding the insulating rod, picking up the high-voltage test line, and making the high-voltage test line perpendicular to the equipment). The angle between the high-voltage test line and the equipment can be made 90°, thereby making the high-voltage electrical test work safer, more efficient and convenient.

[0038] In summary, the high-voltage electrical test line support tool provided by the present invention can make the test line support operation in high-voltage electrical testing safer, more convenient and more efficient, thereby improving the safety and efficiency of high-voltage electrical testing.

[0039] In one embodiment, the clamp 9 includes a first clip 1 and a second clip 2 arranged in cooperation with the first clip 1, the first clip 1 and the second clip 2 are both provided with an arc groove for accommodating the insulating rod, the first end of the first clip 1 and the first end of the second clip 2 are hinged, and the second end of the first clip 1 and the second end of the second clip 2 are correspondingly provided with an installation hole 3, and the installation hole 3 is used to pass the locking member.

[0040] It should be noted that the first end of the first clip 1 and the first end of the second clip 2 are hinged to facilitate relative opening and closing of the first and second clips 1 and 2. Mounting holes 3 are provided at the second ends of the first and second clips 1 and 2, respectively, allowing the first and second clips 1 and 2 to be clamped and secured to the top of the insulating rod via a locking member. Furthermore, one end of a support arm 6 can be vertically secured to either the first or second clip 1 or 2 (the support arm 6 can be positioned in the middle of the clips), while the other end of the support arm 6 is vertically secured to a retaining ring 7.

[0041] In one embodiment, if Figure 1 As shown, the locking member includes a bolt 4 for inserting into the mounting hole 3 and a nut 5 for tightening the bolt 4 .

[0042] When using the clamp 9, first, the first clamp 1 and the second clamp 2 can be opened so that the cylindrical part at the top of the insulating rod is between the first clamp 1 and the second clamp 2. Then, the bolt 4 is passed through the mounting holes 3 of the first clamp 1 and the second clamp 2. Finally, the nut 5 is put on the end of the bolt 4 and tightened to fix the support arm 6 and the clamp 9 on the insulating rod.

[0043] In one embodiment, if Figure 2 As shown, the support arm 6 includes a rotating base 10, a first rod 11, a second rod 12 and a rotating joint 13 for hingedly connecting the first rod 11 and the second rod 12, and the rotating base 10 and the rotating joint 13 are both connected to the motor through a power cord.

[0044] It should be noted that the rotating base 10 can have a built-in motor and battery, and the rotating joint 13 can be a rotating joint with a motor and a gear. The motor of the rotating joint 13 can be connected to the power supply through a power cord. The two motors can be controlled separately. The rotation control of the rotating base 10 and the rotating joint 13 can be achieved by remote control via a remote controller, and the test line can be more accurately controlled to be in a horizontal state perpendicular to the equipment. Moreover, the first rod 11 and the second rod 12 can be a structure with a certain hardness and can be appropriately deformed to ensure that the position of the first rod 11 and the second rod 12 can be effectively adjusted by remotely controlling the operation and rotation of the two motors, and then the position of the limit ring 7 can be adjusted to make the test line perpendicular to the equipment. In addition, after the insulating rod is hung, remote control adjustment can be performed according to the actual rotation and tilt angle of the insulating rod.

[0045] In one embodiment, a Velcro strap 8 is provided at the end of the second rod 12. Specifically, when the high-voltage test wire passes through the retaining ring 7 from the outer end (the end away from the clamp 9) to the inner end (the end closer to the clamp 9) and is connected to the metal hook at the top of the insulating rod, the Velcro strap 8 can be used to secure the high-voltage test wire to the second rod 12, ensuring that one end of the high-voltage test wire is positioned along the first rod 11 and the second rod 12, while the other end of the high-voltage test wire passes through the retaining ring 7 and falls downward.

[0046] In one embodiment, the support arm 6 includes a thin-walled aluminum alloy tube provided on one side of the clamp 9 and a wrapping layer wrapped around the outer periphery of the thin-walled aluminum alloy tube, wherein the wrapping layer includes a silicone layer or a rubber layer to ensure that the support arm 6 has a certain hardness and supporting effect, and that the support arm 6 can bend and deform under force.

[0047] In one embodiment, the support arm 6 is provided with a Velcro strap 8 for securing the high-voltage test wire. Specifically, when the high-voltage test wire passes through the retaining ring 7 from the outer end (the end away from the clamp 9) to the inner end (the end closer to the clamp 9) and is connected to the metal hook at the top of the insulating rod, the Velcro strap 8 can be used to secure the high-voltage test wire to the support arm 6, ensuring that one end of the high-voltage test wire is positioned along the support arm 6 and the other end of the high-voltage test wire passes through the retaining ring 7 and falls downward.

[0048] In one embodiment, the first clip 1 and the second clip 2 are both made of metal or plastic. In other words, whether the first clip 1 and the second clip 2 have conductive properties or insulating properties will not affect the performance of the device. The materials of the first clip 1 and the second clip 2 can be determined based on actual needs.

[0049] In one embodiment, the limiting ring 7 includes an insulating ring to prevent the limiting ring 7 from interfering with the testing process of the high-voltage test line.

[0050] In order to further illustrate the use of the high-voltage electrical test line support tool provided by the present invention, an example is given below.

[0051] To use this device, first, open the first and second clips 1 and 2, positioning the cylindrical portion of the top of the insulating rod within the arcuate grooves of the first and second clips 1 and 2. Then, insert bolt 4 through mounting hole 3 and tighten bolt 4 with nut 5, securing the first and second clips 1 and 2 to the insulating rod. Next, pass the high-voltage test lead through the retaining ring 7 and connect it to the metal hook at the top of the insulating rod. Adjust the angle of the support arm 6 based on the angle at which the insulating rod is attached to the equipment (e.g., the utility pole to be repaired) so that the support arm 6 is perpendicular to the equipment after attachment. Then, secure the high-voltage test lead to the support arm 6 using Velcro straps 8. Finally, attach the insulating rod to the equipment so that the high-voltage test lead is at a 90° angle to the equipment. This eliminates the need for a separate tester to manually lift the rod and maintain a 90° angle between the high-voltage test lead and the equipment. This prevents the operator from being harmed by induced electricity or slipping of the high-voltage test line when the voltage of the high-voltage test line is too high. In addition, the angle between the high-voltage test line and the equipment is 90°, which can minimize the impact of stray capacitance on test accuracy, making high-voltage electrical testing safer, more efficient and convenient, and obtaining more accurate test results.

[0052] In addition to the above-mentioned high-voltage electrical test line support tool, the present invention also provides a high-voltage electrical test device including the high-voltage electrical test line support tool disclosed in the above-mentioned embodiment. For the structures of other parts of the high-voltage electrical test device, please refer to the prior art and will not be repeated in this article.

[0053] It should be noted that the first clip 1 and the second clip 2, the first end and the second end, the first rod 11 and the second rod 12 mentioned in this application document, where the first and the second are only used to distinguish the different positions, have no order of precedence.

[0054] In addition, it should be noted that the orientation or position relationship indicated by "vertical" and the like in this application is based on the orientation or position relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and facilitating understanding, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
