Abstract
The netted earth connection that a kind of not screwing does not weld, being that the lateral surface of rectangular annulus is uniform as the cross section be sleeved on power transmission line electric pole is fixedly connected with the multiple cylinders with this annulus axis parallel, this cylinder and the upper and lower end face of this annulus, and in each cylinder, be plugged with a bonding jumper from bottom to top; Above-mentioned annulus and all cylinders are monoblock cast part.During assembling without screw, without electric welding, for site operation brings great convenience.This device is easy for installation, the cylinder of earth connection is directly enclosed within electric pole root, and then buries electric pole underground, and electric pole is buried underground to lay with earth connection and completed simultaneously.
Description
Technical field
The utility model relates to lightning-arrest earth connection, particularly the lightning-arrest earth connection of power transmission line electric pole.
Background technology
Large in order to change grounding resistance, the situation of thunder and lightning release function difference, the present inventor once made and adopted netted earth connection (as shown in Figure 1 a, 1 b).Many initial earth connections are welded on circular boop surface, like this, although meet connection request.But because first getting the raw materials ready as steel plate, cut out, punching press and be curled into circular etc., so procedure is many, difficulty is relatively large, in addition these work often need having the place of stamping machine and welding equipment to complete, conditional request is high, and after many branch lines are welded into entirety, bring difficulty to assembling, transport.
Utility model content
The purpose of this utility model is to provide the assembling of a kind of plug-in type, the in-site installation not netted earth connection that do not weld of screwing easily.
The purpose of this utility model is achieved in that the netted earth connection that a kind of not screwing does not weld, being that the lateral surface of rectangular annulus is uniform as the cross section be sleeved on power transmission line electric pole is fixedly connected with the multiple cylinders with this annulus axis parallel, this cylinder and the upper and lower end face of this annulus, and in each cylinder, be plugged with a bonding jumper from bottom to top; Above-mentioned annulus and all cylinders are monoblock cast part.
Above-mentioned annulus height is 100mm.
Above-mentioned cylinder is 12.
Compared with prior art, the beneficial effects of the utility model are:
1, bonding jumper only need insert in semicircular cylinder by grounding wire mounting timing successively from bottom to top, during assembling without screw, without electric welding, for site operation brings great convenience.
2, easy for installation.
The cylinder of earth connection is directly enclosed within electric pole root, and then buries electric pole underground, electric pole is buried underground to lay with earth connection and is completed simultaneously.
Accompanying drawing explanation
Fig. 1 a, Fig. 1 b are the schematic diagram (non-fixing metal bar state) of existing circular ring type earth connection and circular boop formula earth connection respectively.
Fig. 2 is the schematic diagram of the cylinder cast member of this earth connection.
Fig. 3 is the schematic diagram of this netted earth connection shown in Fig. 2.
Embodiment
Fig. 2 illustrates, the netted earth connection that a kind of not screwing does not weld, being that the lateral surface of rectangular annulus 1 is uniform as the cross section be sleeved on power transmission line electric pole is fixedly connected with the multiple cylinder 1a with this annulus 1 axis parallel, this cylinder 1a and the upper and lower end face of this annulus 1, and be plugged with a bonding jumper 2 from bottom to top in each cylinder 1a; Above-mentioned annulus and all cylinder 1a are monoblock cast part.Annulus 1 is highly 100mm.Cylinder 1a is 12.
Fig. 3 illustrates, the bonding jumper of insertion is Ф 10mm, so the design of vertical holes internal diameter is also 10mm, therefore becomes to each other and combines closely, add that the height of annulus 1 is that 100mm(internal diameter and electric pole are suitable), be enough to metal strips for grounding line to insert firmly fastening.
This earth connection not screwing does not weld, and adopts direct insertion connected mode, and this cylinder cast member needs to carry out designing and producing of cast dies, although early investment is larger, can reduces workload and form batch production, so highly.
Punching block is primarily of electromagnetic high-temperature stove, steel body patrix, steel body counterdie composition, and wherein high temperature furnace mainly melts molten iron, makes it to flow into from solution channel, to solidify aftershaping.Steel body patrix plays interior gear solution and extracts storing, i.e. demoulding effect, steel body counterdie plays the firm effect of outer gear solution and location, be the difference of the diameter of inside and outside die body up and down, the thickness of annulus just, the height of blending is also the height of annulus, and external mold is with the real core body of multiple 10mm, after the demoulding, be periphery bar hole.
After being made by the annulus of the vertical cylindrical void of band in punching block, can insert 1000mm length on the vertical cylindrical void of annulus periphery, and be bent into the bonding jumper of unified model through crimping, as shown in Figure 3, then the net like lightning protection line of complete set is successful.
