Description
Technical field
The utility model relates to the technical field of earth connection, especially a kind of coupling type short-circuit grounding wire.
Background technology
It is to be used to prevent that equipment, circuit from sending a telegram here suddenly that the coupling type short-circuit grounding wire is hung, eliminate induced voltage, drain the device of the temporary grounding of residual charge, be used for circuit and power transformation construction, for preventing to close on the usefulness that guarantees safety when electrified body produces electrostatic induction electric shock or false switching.
Form because coupling type short-circuit grounding wire front end thoroughly does away with the edge hook stick by three,, realize the work of transmitting up and down so the transmission up and down of shaft tower can only bundle three simultaneously with marline and thoroughly do away with the edge hook stick.The ground service staff bundlees difficulty, and high-altitude workmen Xie Shengnan transmits inconvenience.
Because earth connection thoroughly does away with the edge hook stick by binding three, realize transmitting up and down, so when earth connection is delivered in the workmen's hand of high-altitude, because it is bigger that three eradication edge hook sticks merge volume, a hand can't be held, just must adopt " embracing ", posture such as " shouldering " operates, secondly earth connection weight is bigger, the high-altitude personnel can't hand the insulation hook stick and operate, can only " embrace " hook stick that firmly insulate and carry out the operation of hanging ground-wire, can not guarantee the safe distance (can not less than 0.7 meter) of operating personnel and electrified body, the workmen is when hanging earthing conductor, human body and earth connection contact, and do not have safe distance to say at all.
Grounding pin is stressed when going into ground, because geologic structure there are differences, just there is tie point unbalance stress on the grounding pin when running into geology when hard, occurs bending and deformation easily, have a strong impact in the future and normally use, because former grounding pin need be at the 15cm place, nut is installed in punching, is used to connect earth connection, after the grounding pin punching, destroyed original mechanical strength, grounding pin occurs bending and deformation owing to stressed easily.When grounding pin entered soil under external force, grounding pin was stressed jointly up and down, and stressed excessive back, middle part weak point branch occurs bending and deformation, and Here it is grounding pin in use connects the reason that the part of earth connection bends easily.
Along with social development, living environment is constantly improved, and hardened ground is more and more; so the job site, usually can run into grounding pin can't go into the phenomenon on ground, when running into this situation; can only manage earth connection is connected with near ground network, realize the effect of temporary ground wire.
Now common to ground network have two kinds:
1, the ground network of distribution indoor electric equipment is by being not less than the ground network that the 40*4 zinc-coated flat steel sheet is welded to form;
2, on the electric pole protective earthing net of electric equipment be by the steel strand wire that are not less than LG-25 as downlead, usually there is a short circuit card at the 1.8-2.0m place under electric pole, short circuit Ka Chu is connected to steel strand wire on the ground connection band iron with galvanized bolt.
In these common two kinds of ground networks, when not reserving the connecting hole of temporary ground wire, the site operation personnel also just can't carry out ground connection connection.Some personnel follows the line of least resistance, and just temporary ground wire has been wound on the ground network (band iron, round steel, steel strand wire), and temporary ground wire contact-making surface defective tightness, the poor electric conductivity of Lian Jieing do not have protective effect like this.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the problem that exists in above-mentioned, provide a kind of safe, simple to operate, easy to use and coupling type short-circuit grounding wire that reliably be connected with ground network.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of coupling type short-circuit grounding wire, comprise at least one eradication edge action bars, be arranged on the wire clamp of insulating bar end, earth connection that is connected with wire clamp and the grounding pin that is connected with earth connection, insulating bar is provided with portable annex, portable annex comprises that a side is ringent circular anchor ear, circular anchor ear one side also has opening left arc tips and right arc tips outwardly, all offer at least one pin-and-hole on left side arc tips and the right arc tips, left side arc tips and right arc tips are fastening fixing by latch, and circular anchor ear opposite side is horizontally disposed with and is useful on the iron that hangs wire clamp.
For the ease of grounding pin reliably is connected with ground network, the T type grounding pin that grounding pin is made up of cross bar and montant, cross bar and montant are overall structure, described montant one side and cross bar junction are welded with square iron plate, offer the screw connecting hole on the iron plate; In order to be connected reliably with steel strand wire, band iron, the round steel in the ground network, described montant opposite side and cross bar junction are provided with batt joint ground folder, batt joint ground folder adopts " E " font structure, folder side, batt joint ground offers screwed hole, batt joint ground clamping in the middle of fixing on iron plate and the gap between the left side greater than and the right side between the gap, batt joint ground folder is screwed into screwed hole by galvanized screw, can be connected reliably with steel strand wire, band iron, the round steel in the ground network.
In order to prevent to get rusty with oxidized, described grounding pin, an iron plate peace mouthful earth clip outer surface all are coated with the zinc layer.
In order to prevent that other two thoroughly do away with the edge action bars and are hung on the iron in the laggard line operate process, thereby owing to occur tilting to cause insulating bar to skid off that iron is outer to cause unnecessary loss, end, described iron two ends bends up.
For can circular anchor ear is more fastening fixing, all offer two pin-and-holes on described left arc tips and the right arc tips.
In order to improve insulation property and mechanical strength, described insulating bar is made by epoxy resin and glass fibre.
Described earth connection covers the transparent insulation sheath outward by copper soft whipping wire and makes the sectional area 〉=25mm of copper soft whipping wire
2
Sectional area 〉=the 190mm of described grounding pin
2
For can handled easily, described insulating bar quantity be three.
The beneficial effects of the utility model are, coupling type short-circuit grounding wire of the present utility model, adopt portable annex to be fixed on the insulating bar in the coupling type short-circuit grounding wire, other two insulating bars are attached to portable annex both sides, only just can control the operation of whole coupling type short-circuit grounding wire with operation intermediate insulation bar, it is very convenient, simple to operate, the high-altitude application personnel have also guaranteed safe distance, during high-altitude application under the effect of gravity, intermediate insulation bar and both sides insulating bar are not at grade, so just simplified operating environment, it is more directly perceived to operate; On former grounding pin, offer the screw connecting hole,, just can reliably connect easily by galvanized screw as long as the ground connection of reservation screw hole is arranged in the ground network; Add batt joint ground folder on former grounding pin, batt joint ground folder can be connected with steel strand wire, band iron, the round steel in the ground network reliably by the effect of galvanized screw; For preventing that grounding pin from going in the ground process stressed, little because of load contact cross section, unbalance stress occurs bending and deformation, and grounding pin adopts whole shape grounding pin, and the load contact installs the band iron increasing section additional, is subjected to force intensity thereby reduce, and reduces the distortion that produces owing to stressed.
