Embodiment 1

[0032] combine figure 1 As shown, a shielding cover for an overhead wire insulation layer disclosed in this embodiment includes a flexible insulating cover body 1 and a connecting part 2 . Specifically, the material of the flexible insulating cover 1 is a soft insulating material, such as rubber or foam. The flexible insulating cover 1 includes a wire covering ring 11, a first connecting plate 12 and a second connecting plate 13. The wire covering ring 11 is not a closed ring, but a ring with a gap (that is, a ring with a lower opening), that is, the wire The two ends of the cladding ring 11 are spaced apart. Moreover, the wire covering ring 11 has a certain length in the axial direction, and the length is selected according to actual needs, that is, according to the position and range of the exposed point of the overhead wire, so as to select a length that can completely cover the exposed point. The first connecting plate 12 and the second connecting plate 13 are respective...

Embodiment 2

[0036] This embodiment also provides a fitting for the overhead conductor insulating layer shield described in Embodiment 1, which includes a hanging part 3 and a clamping part 4 . combine Figure 2 to Figure 5 As shown, specifically, the hanging part 3 has a delivery rod 31 and a hanging ring 32 fixed on one end of the delivery rod 31, a hanging notch is formed under the hanging ring 32, and the hanging ring 32 is used to The insulating layer shielding cover of the overhead wire is clamped to facilitate the positioning of the insulating layer shielding cover of the overhead wire; wire, so as to avoid the operator climbing up and reduce the risk of the operator; and by manipulating the conveying rod 31, the wire-passing opening of the clamped overhead wire insulation layer shield can be aligned with the overhead wire, and aligned with the rearward hanging slot Pull the conveying rod 31 in the direction of the opening, and the conveying rod 31 pushes the hanging ring 32, so th...

Abstract

The invention discloses an overhead conductor insulating layer shielding cover and an installation fitting thereof. The shielding cover for the insulating layer of the overhead conductor comprises a flexible insulating cover body and a connecting part, and the flexible insulating cover body wraps the overhead conductor at an exposed point through the connecting part; the mounting fitting comprisesthe hanging part and the clamping part, the hanging part comprises the conveying rod and the hanging ring, the clamping part comprises the operating rod, the pulling and pressing mechanism and the clamp, the shielding cover can be clamped through the hanging ring and conveyed to an overhead conductor with an exposed point through the conveying rod, and the conductor can be pushed into the conductor wrapping ring by pulling the conveying rod; and then the tension and compression mechanism is controlled to drive the clamp to clamp the connecting rods on the first connecting plate and the connecting holes in the second connecting plate in a one-to-one correspondence mode, operation is easy and convenient, the influence of the technical level of construction personnel is avoided, and good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of shielding covers, in particular to a shielding cover for insulating layers of overhead wires and fittings for installation thereof. Background technique [0002] In the operation and maintenance of 10kV overhead insulated conductors, the outer insulation layer is often damaged due to the installation of clamps and other hardware. Many clamps are temporarily installed. Because the insulation layers of the three-phase wires are damaged at the same time, once trees, hanging objects, etc. touch the exposed points of the two-phase wires at the same time, it is easy to cause a phase-to-phase short circuit accident. Furthermore, if a kite, fishing rod line, etc. are hung on the exposed point of the wire, a grounding accident will easily occur, and even cause casualties. At the same time, due to the gap between the inner metal wire and the outer insulating layer of the wire, it is easy to enter rainwater, corros...
