Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment for insulating shielding tools used in live-line work, and specifically to a testing equipment for insulating protective covers used in live-line work. Background Technology

[0002] The insulating cover is made of natural silicone rubber, heat-shrinkable materials, and anti-aging polymer insulating materials. It maintains good flexibility even in cold weather and protects against ozone and ultraviolet damage. It effectively prevents power outages, damage to electrical equipment, and electric shocks caused by phase-to-phase short circuits or grounding due to various factors (wet flashover, pollution flashover, salt spray, chemical gas corrosion, human contact, small animals or debris touching the wires, etc.) at various exposed joints. This ensures the safe operation of electrical equipment.

[0003] Chinese patent document CN213149151U discloses a test device for insulation shielding tools for live-line working in power distribution networks, including a support assembly and a high-voltage assembly mounted on the support assembly. The support assembly includes an insulating support plate, with insulating support rods symmetrically arranged around the perimeter of the insulating support plate. Insulating connecting plates are symmetrically arranged on both sides of the upper end of the insulating support plate, and both ends of the symmetrically arranged insulating connecting plates are connected to the symmetrically arranged insulating support rods. Multiple metal rods are penetrating through the symmetrically arranged insulating connecting plates. The high-voltage assembly includes metal rods, with a high-voltage mother plate penetrating through one end of the metal rods away from the insulating connecting plates. A high-voltage power supply line is provided at one end of the high-voltage mother plate.

[0004] However, when using the above method, different shaped insulating shields are placed on an insulating support plate, test electrodes are installed on the insulating shields, and a power frequency withstand voltage test is performed. However, due to the variety of shapes of the insulating shields and the fact that the insulating support plate is a flat plate, it is difficult to ensure that the test electrodes are in full contact with the insulating parts when placing the insulating shields, which leads to errors in the test data.

[0027] Example 1

[0028] like Figure 1-4 As shown, the present invention proposes a live-line working insulation protective cover testing device, which includes a support frame 1, a support plate 2, a clamping assembly 3, a connecting block 4, and a limiting rod 9;

[0029] There are two connecting blocks 4, which are installed on both sides of the inside of the support frame 1 and are arranged symmetrically.

[0030] The support plate 2 is slidably installed between two connecting blocks 4. The top of the support plate 2 is provided with multiple clamping components 3 for limiting the position of the insulating protective cover in use. The multiple clamping components 3 are evenly distributed on the top of the support plate 2.

[0031] The limiting rod 9 is located on the outside of the support frame 1 and passes through the support frame 1 and the connecting block 4 to connect to the support plate 2.

[0032] In this embodiment, by pulling the support plate 2, the support plate 2 slides towards the front of the support frame 1 between the two connecting blocks 4, allowing the insulation protective cover to be placed above the support plate 2 without obstruction. At the same time, by evenly distributing multiple clamping components 3 on the top of the support plate 2, the multiple clamping components 3 fix the insulation protective cover placed on the upper surface of the support plate 2 and limit its position, ensuring the stability of the insulation protective cover and avoiding the situation where the spacing between multiple insulation protective covers is too small. The support plate 2 is then reset so that it is located inside the support frame 1. At the same time, the limiting rod 9 passes through the support frame 1 and the connecting block 4 and is connected to the support plate 2, realizing the fixed connection between the support plate 2 and the connecting block 4, preventing the support plate 2 from moving during the detection process, making the placement of the insulation protective cover more convenient. Furthermore, by clamping and limiting the insulation protective cover with the clamping components 3, the detection accuracy is improved.

[0033] Example 2

[0034] like Figure 1-3As shown, the present invention proposes a live-line working insulation protective cover testing device. Compared with the first embodiment, the difference in this embodiment is that both sides of the support plate 2 are provided with sliding strips 5, and the side of the connecting block 4 is provided with a first sliding groove 6. When the support plate 2 and the connecting block 4 are installed together, the sliding strips 5 are accommodated in the first sliding groove 6.

[0035] In an optional embodiment, a slot 8 is provided on one side of the slide bar 5, and the end of the limiting rod 9 passes through the support frame 1 and the connecting block 4 and is inserted into the slot 8.

[0036] In this embodiment, the cooperation of the slider 5 and the first sliding groove 6 allows the support plate 2 to slide between the two connecting blocks 4 towards the front of the support frame 1, and one end of the support plate 2 is placed horizontally at the front of the support frame 1, making the installation of the insulating protective cover more convenient. After the support plate 2 is reset, the limiting rod 9 is inserted into the slot 8 through the support frame 1 and the connecting block 4, so that the support plate 2 is fixedly installed between the two connecting blocks 4 through the slot 8, avoiding the support plate 2 from moving during the testing process.

[0037] Example 3

[0038] like Figure 3-4 As shown, the present invention proposes a live-line working insulation protective cover testing device. Compared with the first embodiment, the difference in this embodiment is that the clamping component 3 includes a limiting plate 31, a bolt 32 and a slider 33.

[0039] There are two limiting plates 31, and the two limiting plates 31 are symmetrically installed on the upper end surface of the support plate 2;

[0040] The slider 33 is located at the bottom end of the limiting plate 31 and is slidably connected to the support plate 2;

[0041] Bolt 32 is located at the top of the limiting plate 31 and passes through the limiting plate 31 and the slider 33 to connect with the support plate 2.

[0042] In an optional embodiment, the cross-sectional projection shape of the limiting plate 31 is L-shaped, and one side of the limiting plate 31 is comb-shaped, which is used to squeeze the insulating protective cover during use and reduce the contact area between the insulating protective cover and the limiting plate 31.

[0043] In an optional embodiment, both the end faces of the limiting plate 31 and the slider 33 are provided with threaded holes 34, and the bottom end of the bolt 32 is inserted into the inner side of the threaded hole 34 and connected to the support plate 2.

[0044] In this embodiment, the position of the limiting plate 31 is limited by the sliding connection between the sliders 33 and 23, so that the two limiting plates 31 are installed symmetrically, and the two limiting plates 31 are fixed to the support plate 2 by the bolts 32, so that the two limiting plates 31 fix the insulating protective cover, making the installation of the insulating protective cover more convenient.

[0045] Example 4

[0046] like Figure 3 As shown, the present invention proposes a live-line working insulation protective cover testing device. Compared with the first embodiment, the difference in this embodiment is that the top of the support plate 2 is provided with a plurality of second sliding grooves 7 with both ends through. When the slider 33 is installed in conjunction with the support plate 2, the slider 33 is accommodated in the second sliding grooves 7. The end of the second sliding groove 7 is located on the side of the connecting block 4, which is used to block the end of the second sliding groove 7 when the support plate 2 is located between two connecting blocks 4.

[0047] In an optional embodiment, the projection shape of the support plate 2 is U-shaped, and the slide bar 5 is located on the side of the U-shaped end of the support plate 2. It is used to create a gap between the second slide groove 7 and the slide bar 5 during use, so as to prevent the slide bar 5 from blocking the slider 33 in the second slide groove 7.

[0048] In this embodiment, by cooperating with the second slide groove 7 and the connecting block 4, when the support plate 2 is located inside the support frame 1, the end of the second slide groove 7 is in a blocked state, preventing the slider 33 from falling off. And by the slider 33 being located inside the second slide groove 7, the two limiting plates 31 can only move towards each other or away from each other, so that the distance between the two limiting plates 31 can be adjusted, and the two limiting plates 31 can clamp and fix insulating protective covers of different shapes and sizes.

[0049] In this invention, the limiting rod 9 is separated from the slot 8, and the support plate 2 is pulled towards the front of the support frame 1, causing the support plate 2 to drive the slider 5 to slide inside the first slide groove 6. When one end of the support plate 2 is located at the front of the support frame 1, the slider 5 and the first slide groove 6 cooperate to support the support plate 2, allowing the upper end of the support plate 2 to be placed with an insulating protective cover. At the same time, the bolt 32 is tightened to separate the bolt 32 from the support plate 2, and the limiting plate 31 drives the slider 33 to slide inside the second slide groove 7, adjusting the position of the limiting plate 31. When the two limiting plates 31 press against the insulating protective cover, the bolt 32 is connected to the support plate 2 in the threaded hole 34, fixing the position of the limiting plate 31 and fixing the insulating protective cover. The support plate 2 drives the slider 5 to reset, and the end of the limiting rod 9 is inserted into the slot 8 to fix the position of the support plate 2, allowing the insulating protective cover on the support plate 2 to be inspected.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
