Description

Ground connection link insulating cover
Technical field
The utility model relates to ground connection link insulating cover, and more specifically, it relates to a kind of ground connection link insulating cover being mainly used in power engineering 10kV ground connection link exposed part.
Background technology
The object of line insulation is the fail safe improving circuit, just in case metal object, trees contact wire can not cause single-phase earthing or line short, even contingency human contact wire also can reduce Danger Electric shock risk to a certain extent.But when line upkeep or maintenance in order to ensure the safety of maintainer, insulated wire must be carried additionally ground connection link for hanging earthing conductor.And the setting up of ground connection link, the exposed part of its earth connection hanging point exactly reduces the insulation property of circuit, reduces the fail safe of circuit itself.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of rational in infrastructure, the ground connection link insulating cover that fail safe is high.
This ground connection link insulating cover, comprise the cross bar be located on ground connection link, two vertical poles and an insulating case, the upper end of described vertical pole is provided with through hole, lower end is provided with the insulating barrier phase apical grafting of leg ring and ground connection link bottom, two vertical poles penetrate the two ends of cross bar respectively by through hole, the two ends of described cross bar are provided with snap ring, and described snap ring may be stuck on two side insulation layers of ground connection link; Described insulating case upper end is provided with can button hook, and described button hook embeds cross bar, and described insulating case lower end is provided with the cover body that can coordinate with earth connection hanging point, and described insulating case is provided with osculum on cover body top.
As preferably: described ground connection link comprises fixture, conductive layer and insulating case, described conductive layer is connected with wire by fixture, conductive layer is rectangle link, described fixture and conductive layer are wrapped up by insulating case, be the conductive layer exposed part not having insulating case in the bottom of rectangle link, form earth connection hanging point; Described earth connection hanging point cooperation is provided with earth connection head, and described earth connection head is provided with hook, is provided with the barb that two panels offsets in described hook.
The beneficial effects of the utility model are: 10kV overhead transmission line insulating is the inevitable requirement of line security and operation, and the object that ground connection link is arranged is the safety in order to ensure maintainer, but ground loop exposed part becomes the short slab of insulated circuit.When trees cannot be cut down more greatly or metallicity foreign material disorderly fly in inclement weather, the existence of ground loop just likely result in the generation of line fault.After using this device, do not affecting under the prerequisite that hangs of electric power overhaul construction earth connection, the perfect to a certain extent insulating properties of ground loop exposed part, facilitates the operation that line security is stable to a certain extent.

Embodiment
Below in conjunction with embodiment, the utility model is described further.The explanation of following embodiment just understands the utility model for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection range of the utility model claim.
This ground connection link insulating cover, comprise cross bar 4, two vertical pole 8 and the insulating case 7 be located on ground connection link, the upper end of described vertical pole 8 is provided with through hole 13, lower end is provided with the insulating barrier 2 phase apical grafting of leg ring 15 and ground connection link bottom, two vertical poles 8 penetrate the two ends of cross bar 4 respectively by through hole 13, the two ends of described cross bar 4 are provided with snap ring 12, and described snap ring 12 may be stuck on two side insulation layers 2 of ground connection link; Described insulating case 7 upper end is provided with can button hook 11, and described button hook 11 embeds cross bar 4, and described insulating case 7 lower end is provided with the cover body 14 that can coordinate with earth connection hanging point 5, and described insulating case 7 is provided with osculum 16 on cover body 14 top.
Described ground connection link comprises fixture 3, conductive layer 6 and insulating case 7, described conductive layer 6 is connected with wire 1 by fixture 3, conductive layer 6 is rectangle link, described fixture 3 and conductive layer 6 are wrapped up by insulating case 7, be conductive layer 6 exposed part not having insulating case 7 in the bottom of rectangle link, form earth connection hanging point 5; Described earth connection hanging point 5 cooperation is provided with earth connection head 17, and described earth connection head 17 is provided with hook 9, is provided with the barb 10 that two panels offsets in described hook 9.
The utility model is formed primarily of three parts, specific as follows:
(1) cross bar 4: can be made up of the stainless bending reinforcement of the sufficient intensities such as Φ 6 or Φ 8, two ends arrange bayonet socket, flexible, dimensional fits ground connection link.
(2) vertical pole 8: material can with cross bar 4, and head arranges annulus, and diameter coordinates with cross bar bar diameter.Bottom is semi-circular bracket, and for propping up above ground connection link lateral part, height need coordinate with ground connection link.
(3) insulating case 7: be made up of the flexible insulating material of band, head-bent, hooks into cross bar 4.A shape is made in bottom, and conductor covers the most at last.Centre arranges osculum 16.Width and the aspect ratio ground connection link of insulating case are smaller, also need to coordinate with ground connection link.
Operation instruction:
First 2 vertical poles are inserted in cross bar 4, secondly cross bar 4 are embedded ground connection link, then again insulating case 7 is embedded cross bar 4, finally regulate cross bar 4 setting height(from bottom), vertical pole 8 just can be propped up on ground loop, cross bar 4 is not glided, and make insulating case 7 just can be enclosed within ground loop exposed part.
Before hanging earthing conductor, under the protection of this device, ground loop exposed part substantially can be made suitably to surround.Note direction a little when hanging earthing conductor, just can hang up very smoothly.After separating earth connection, under gravity, insulating case 7 can restore to the original state automatically.
