04 divisional application.
Technical field
The present invention relates to electric power overhaul instrument, more particularly to a kind of all insulation ground loop.
Background technology
At present, it is general in the circuit of urban distribution network all to be laid using aerial insulated wire, but when circuit or equipment is overhauled,
In order to ensure the safety of maintainer, it is necessary to identify circuit without hanging ground protection line after electricity.This is required in hanging earthing conductor,
Earthing clamp must be contacted reliably with electric wire, and insulated wire can not be hung, so using electricity testing grounding ring.
Existing ground loop when not in use, its working position（Metallic conductor）It is exposed outside, one is blown running into sleet
During weather, the branch for easily causing humidity is overlapped on working position, causes short circuit, influences the normal operation of power supply, causes civilian
The inconvenience of electricity and commercial power.Even if two is that, in normal weather, the surface for often occurring now has floaing for metallic conduction material
Band（Fireworks residue）, kite（Line）And the debris for flying away with the wind are also possible to touch the exposed position of ground loop, cause
Line tripping.
State Intellectual Property Office is CN102882026A in the publication No. that 2013.01.16 is announced, entitled " to carry and renovate
The integrated insulator and earthing clamp of isolation safety cover ", the junction of earthing clamp and power line is enclosed in one by it
In the safety guard of insulation, and using renovating the connection ring of covering earthing clamp, it is to avoid extraneous sleet is to junction and connection ring
Corrode for a long time, it is ensured that power circuit long-term safety is run；Also the possibility of exposed junction electric leakage has effectively been prevented.
The case is entirely covered ground loop, increases production cost；Meanwhile, the case insulator and earthing clamp are connected,
Therefore, just facilitate connection to renovate only on the basis of safety guard, do not possess versatility, bad adaptability；In the prior art, it is grounded
Ring works independently, and renovating in the case is installed in inconvenience additional；Even if installing additional, ground loop is vertically arranged, and causes operation inconvenience, does not reach pre-
The using effect of phase, poor reliability increased cost of labor.
The content of the invention
The present invention is directed to problem above, there is provided a kind of features simple structure, convenient covering ground loop bare metal part, effectively
Moist branch overlap joint is avoided to cause the ground loop of short circuit.
The technical scheme is that：Including ground connection ring body, the ground connection ring body includes that metallic conductor and insulation are protected
Set, the insulating sheath is set on the metallic conductor, and the base of the ground connection ring body is exposed, be ground section；Also include
Switching mode protection mechanism, the switching mode protection mechanism is located on the insulating sheath, for covering or exposing the ground section.
The switching mode protection mechanism includes pipe sleeve and protective cover, and the pipe sleeve is set in the adjacent insulation of the ground section
On sheath, the protective cover is hinged on the pipe sleeve towards one end of the ground section.
The switching mode protection mechanism includes convex on the insulating sheath of protective cover side adjacent with the ground section is located at
Ear, the protective cover is hinged on the lug.
The body of the protective cover takes the shape of the letter U, and the top both sides peristoma of the protective cover is respectively equipped with the flexibility being oppositely arranged
Rib, for the ground section to be enclosed in the protective cover.
The flexible rib is in the form of sheets.
The flexible rib is curved on cross section.
The flexible rib is in inverted T-shaped on cross section.
The bottom of the flexible rib is located at the inner side on the protective cover top.
The protective cover bottom is provided with draw ring.
The present invention increased switching mode protection mechanism in the ground section of dead ring, be easy to do not working dead ring ground section
In the case of covered, it is to avoid cause in the weather such as blowing and raining branch overlap joint, abnormal contact etc. the phenomenon of line short, protect
The normal work of circuit is demonstrate,proved.Switching mode protection mechanism is hinged by protective cover, completes to cover ground section, simple and easy to apply；Anti-
The top of shield sets flexible rib, realizes fully closed environment, improves reliability and service life.In operation, operation
Personnel can be left behind, be pushed to the operation of draw ring using insulating bar on the ground, be disassembled without pole-climbing, simple to operate.
Easy to operate, wide adaptability of the invention, reliability is high.
