Description

A protective cover for grounding wires

technical field

The utility model relates to the technical field of ground wires.

Background technique

In the maintenance work of power transmission equipment, the most important safety measure is to install the ground wire. Before the maintenance starts, the power transmission equipment is powered off and the ground wire is installed. After the maintenance, the ground wire must be removed. The use of qualified grounding wires is one of the most important measures to ensure the safety of people and equipment. The grounding wires are frequently used during maintenance operations, and the insulating skin of the grounding wire connection is broken due to repeated dragging and forceful use of angles or frequent bending. Falling off often causes the copper wire of the grounding wire to be exposed, which further causes the copper wire to wear and tear to cause broken strands, and the cross-sectional area of the copper wire forming the grounding wire is reduced, which becomes a potential safety hazard in the maintenance work.

Utility model content

The technical problem to be solved by the utility model is to provide a grounding wire protective cover, which has the characteristics of preventing the metal wire of the grounding wire from being worn and broken, prolonging the service life of the grounding wire, and ensuring safe production.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a grounding wire protective cover, including a grounding wire hook and a metal wire provided with a first wire nose connecting plate; and a first spring sheath, the The first spring sheath is sleeved on the left end of the metal wire to expose the left end of the metal wire, and the left end of the metal wire is connected to the first wire lug connecting plate.

The further improvement made to the utility model is: it also includes a second spring sheath, a second wire lug connecting plate and a ground wire flat iron; the second spring sheath is sleeved on the right end of the metal wire and exposes the right end of the metal wire , the right end of the metal wire is connected with the second wire lug connecting plate, and the ground wire flat iron is connected with the second wire lug connecting plate. Both the first spring sheath and the second spring sheath are coiled by spring steel wires and tightly sheathed outside the insulating layer of the metal wire.

The beneficial effects produced by adopting the above-mentioned technical scheme are: the spring sheath of the utility model is set outside the insulating layer of the metal wire, which increases the strength and elasticity of the end of the metal wire of the ground wire, and can prevent the ground wire from being damaged during use. The metal wires are bent and broken due to repeated dragging, so as to ensure that the cross-sectional area of the metal wires is not reduced, the conductivity is not reduced, the service life of the grounding wires is extended, safe production is ensured, and maintenance work efficiency is improved.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model. the

As shown in the figure: 1 ground wire hook, 2 connecting sleeve, 3 ground wire insulation rod, 4 first wire nose connecting plate, 5 first spring sheath, 6 metal wire, 7 second spring sheath, 8 second wire Nose connection plate, 9 ground wire flat irons.

Detailed ways

In contrast to Fig. 1, the operation steps of the present utility model are further described:

Embodiment 1: A grounding wire protective cover, including a grounding wire hook 1 provided with a first wire lug connecting plate 4 and a metal wire 6; it also includes a first spring sheath 5, and the first spring sheath 5 is set on The left end of the metal wire 6 exposes the left end of the metal wire 6 , and the left end of the metal wire 6 is connected to the first wire lug connecting plate 4 . It also includes a second spring sheath 7, a second wire lug connecting plate 8 and a ground flat iron 9; the second spring sheath 7 is set on the right end of the metal wire 6 and exposes the right end of the metal wire 6, and the metal wire 6 The right end of the ground wire is connected with the second wire lug connecting plate 8, and the ground flat iron 9 is connected with the second wire lug connecting plate 8. How to use: Both the first spring sheath 5 and the second spring sheath 7 are polished at both ends without burrs and sharp corners, the length is 8cm, and the outer diameters are 10mm, 12mm and 14mm respectively. It is matched with the metal wire 6 used for grounding, and the inner diameter is slightly smaller than the diameter of the outer peripheral insulating sleeve of the metal wire 6 . By installing the first spring sheath 5 and the second spring sheath 7, the situation that the two ends of the metal wire 6 are bent to death is avoided, and the broken strands of the metal wire 6 due to wear and tear are protected, thereby ensuring the safety of personnel and equipment at the job site. Safety.

Embodiment 2: A grounding wire protective cover, including a grounding wire hook 1 provided with a first wire lug connecting plate 4 and a metal wire 6; it also includes a first spring sheath 5, and the first spring sheath 5 is set on The left end of the metal wire 6 exposes the left end of the metal wire 6 , and the left end of the metal wire 6 is connected to the first wire lug connecting plate 4 . It also includes a second spring sheath 7, a second wire lug connecting plate 8 and a ground flat iron 9; the second spring sheath 7 is set on the right end of the metal wire 6 and exposes the right end of the metal wire 6, and the metal wire 6 The right end of the ground wire is connected with the second wire lug connecting plate 8, and the ground flat iron 9 is connected with the second wire lug connecting plate 8. Both the first spring sheath 5 and the second spring sheath 7 are coiled by spring steel wire and tightly wrapped outside the insulating layer of the metal wire 6 .
