Description

Technical Field

[0001] The present invention relates to a hard shielding cover that can be installed at ground potential for insulating protection of an AMP clamp. Background Art

[0002] With the increasingly improved ecological environment, in addition to the increasing number of small animals such as squirrels and birds, the number of large birds such as magpies is also increasing day by day. Magpies are birds good at building nests and especially like to choose to build nests at the crossarms of electric poles, and like to build nests repeatedly at a certain point within a specific environmental range. Even if power construction personnel remove the bird nests on the electric poles, the next day, power inspection personnel can still see the prototype of the bird nests being built.

[0003] Especially at the double crossarm segmented corner tension position, where the corner branch connection of two lines is connected by an AMP clamp, and is externally wrapped with insulating tape or equipped with an AMP clamp insulating sheath. The foundation for building the bird nest branches is constructed with thick, large, and long branches or iron wires, directly wrapping the AMP clamp together with the external insulating protection, greatly reducing the insulation level at the connection of the AMP clamp, and seriously threatening the safe operation of the distribution line power.

[0004] The externally wrapped insulating tape has the risk of aging and loosening due to wind, sun, and rain, while the AMP clamp insulating sheath can only prevent short-term contact by general foreign objects. Once the branches are wet by rain, the insulating protection outside the AMP clamp becomes ineffective and there is no insulation protection at all, which may lead to a long-term continuous ground short circuit of the line, and the line cannot be successfully reclosed after tripping, seriously affecting the power supply reliability of the line. Summary of the Invention

[0044] Two rotary door-closing basic structures 13 are arranged on the top of the η-shaped main structure 11, one on the left and one on the right. The two rotary door-closing basic structures 13 are used to connect the L-shaped door-closing shield 3. Each rotary door-closing basic structure 13 is provided with a rotary door-closing fixing module 2. A rotary cavity for connecting the L-shaped door-closing shield 3 is formed between the rotary door-closing fixing module 2 and the rotary door-closing basic structure 13.

[0045] The two openings on both sides of the η-shaped main structure 11 respectively form wire clamping grooves 14. The central part of the η-shaped main structure 11 is sleeved outside the AMP wire clamp. The wire clamping grooves 14 are used for clamping the wires at both ends of the AMP wire clamp; an iron sheet inlay structure 15 is arranged in the middle of the outer wall of the shorter side of the η-shaped main structure 11. An iron sheet is inlaid on the iron sheet inlay structure 15.

The rotary activity groove 22 and the anti-rotation limit card slot 25 are located in the center of the fixed connection main body 21, one in front and one behind. The four connecting cylinder caps 24 are symmetrically distributed in pairs at the bottoms of the left and right sides of the fixed connection main body 21. A rotary pillar activity groove 23 is arranged between the two connecting cylinder caps 24 on each side.

[0048] The four connecting cylinder caps 24 are connected to the four connecting cylinders of the rotary door-closing basic structure 13 of the η-shaped shield 1 one by one and fixed tightly with self-tapping screws; each rotary pillar activity groove 23 and the corresponding rotary pillar concave support of the rotary door-closing basic structure 13 of the η-shaped shield 1 form a rotary cavity.

[0049] Please refer to Figure 5 The L-shaped door-closing shield 3 is composed of an L-shaped main structure 31, a strong magnetic installation structure 34, two rotary connection pillars 32 and two adjustment connection structures 33. The L-shaped main structure (31) is a left-right symmetric structure.

[0050] Two rotating connection struts 32 are arranged at both ends of the top of the L-shaped main structure 31; a strong magnetic mounting structure 34 is located at the central position of the long side of the L-shaped main structure 31. The outer side of the strong magnetic mounting structure 34 is insulated and wrapped, and strong magnets are installed on the inner wall. After the live construction installation on the pole is completed, the iron sheets of the iron sheet inlay structure 15 of the η-shaped shield 1 and the strong magnets of the strong magnetic mounting structure 34 of the L-shaped closing shield 3 are adsorbed to each other to ensure that the hard shielding cover is in the closed state. Two adjustment connection structures 33 are correspondingly arranged on both sides of the long side of the L-shaped main structure 31.

[0051] Two rotating connection struts 32 are rotatably arranged in the rotating circular cavity formed by two rotating closing basic structures 13 and a rotating closing fixing module 2 correspondingly; two adjustable closing modules 4 are correspondingly clamped on the two adjustment connection structures 33.

[0052] Specifically, each rotating connection strut 32 includes a rotating movable connection structure and a rotating strut. A convex block is arranged on the rotating strut, and the convex block is used for clamping and matching with the anti-rotation limit card slot 25 of the rotating closing fixing module 2 to ensure that the L-shaped closing shield 3 is always in the open state during live installation.

[0053] Each adjustment connection structure 33 includes three cylindrical connection caps arranged in sequence from top to bottom, which are used for the adjustment and installation of the upper and lower two positions of the adjustable closing module 4 in the vertical direction.

[0054] Please refer to Figure 6 , each adjustable closing module 4 is composed of a closing main structure 41 and two connecting cylinders 42; the two connecting cylinders 42 are arranged one above the other on one side of the closing main structure 41, and the two connecting cylinders 42 are correspondingly connected to any two adjacent cylindrical connection caps of the corresponding adjustment connection structure 33 and fixed by self-tapping screws. The adjustable closing module 4 can also be disassembled for the branch connection of the Amp clamp to meet the insulation hard isolation protection requirements of whether the Amp clamp is segmented connection or branch connection, and the position of the Amp clamp is insulated and wrapped as much as possible to achieve the shielding protection effect of the hard insulation partition.

[0055] The live-potential-installable hard shielding cover for the insulation protection of the Amp clamp of the present invention, due to its specific structure formed by hard insulation materials and ingenious combination and assembly, is suitable for the insulation protection of Amp clamps in various installation scenarios, including segmented crossing, corner tension and line branch positions. Compared with the traditional soft silicone rubber material outer sleeve, it has many advantages. It can be used as the insulation protection cover for the Amp clamp during normal power outage maintenance, and can also realize the live installation operation on the pole, and realize the anti-external-break live installation of the Amp clamp position on the line.

[0056] The rigid shielding cover for insulating protection of AMP wire clamps of the present invention is designed to insulate and shield the high-voltage energized parts of the AMP wire clamps themselves. By providing an insulating gap between the inner cavity of the rigid shield and the body of the AMP wire clamp, it can improve the insulation level against contact or bridging foreign objects outside the rigid shielding cover at the high-voltage energized parts, enhance the protection level against external damage by small animals or branches of bird nests, and improve the reliability of power supply for the distribution network.
