Abstract
A kind of lightning protection downlead syndeton, it is characterized in that: comprise a downlead connection flat bar and an earth electrode connection flat bar, the end of two connection flat bars all has screwed hole, also comprise curving in the middle of one and to roll over outside semicircle, two ends and to be positioned at the flat bar of length in a plane, long flat bar is rolled over end outward and is had connecting hole corresponding to connection flat bar end thread hole, all flat bars are all electric conductors, and long flat bar bolt is connected with two connection flat bars.The beneficial effects of the utility model are: lightning protection downlead is convenient to be disconnected to realize to use connector syndeton, also can dead earthing.
Description
Technical field
The utility model relates to a kind of syndeton of equipment access earth mat, especially relates to a kind of lightning protection downlead syndeton.
Background technology
Earthing device is the general name of earth electrode (imbedding in ground and the one group of metallic conductor directly contacted with the earth) and down conductor (metallic conductor that electrical equipment grounding part is connected with earth electrode).Its effect is by reducing earth resistance, accelerates the diffusion of earth current, reduces earthy rising.The important role of earthing device in transformer station, an earthing device required of conforming to the standard, when can ensure that earth fault occurs in transformer station, ensures the safety of the person and equipment
Whether the down conductor of power plant, transformer station is connected good with ground network, whether the earth electrode of ground network stands intact, very important to the safe operation of electric power system.In " the preventing 25 important requirements of electrical production major accident " of former State Power Corporation, require to carry out one-shot measurement to the down conductor of the power plant in effectively earthed system, transformer station, the conduction status of earth grid every year.The degree of the corrosion of down conductor, earth grid is judged, to determine whether excavate process by the situation of change of all previous measured result of com-parison and analysis.At present, engineering ground lightning protection downlead does not have cut-off point easily, therefore inconvenient when carrying out earth resistance and other needs to take earth connection apart, requires great effort consuming time.
Utility model content
Technical problem to be solved in the utility model, be just to provide a kind of dismounting simple, connect firm lightning protection downlead syndeton.
To achieve these goals, the utility model by the following technical solutions.
A kind of lightning protection downlead syndeton, it is characterized in that: comprise a downlead connection flat bar and an earth electrode connection flat bar, the end of two connection flat bars all has screwed hole, also comprise curving in the middle of one and to roll over outside semicircle, two ends and to be positioned at the flat bar of length in a plane, long flat bar is rolled over end outward and is had connecting hole corresponding to connection flat bar end thread hole, all flat bars are all electric conductors, and long flat bar bolt is connected with two connection flat bars.
The beneficial effects of the utility model are: lightning protection downlead is convenient to be disconnected to realize to use connector syndeton, also can dead earthing.
Accompanying drawing explanation
Fig. 1 is composition of the present utility model and annexation cross-sectional schematic;
Fig. 2 is the right view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As depicted in figs. 1 and 2, lightning protection downlead syndeton of the present utility model, comprise a downlead connection flat bar and an earth electrode connection flat bar, the end of two connection flat bars all has screwed hole, also comprise curving in the middle of one and to roll over outside semicircle, two ends and to be positioned at the flat bar of length in a plane, outer folding end has the connecting hole corresponding to connection flat bar end thread hole, all flat strip adoption copper bars make, smooth vertical and horizontal, specification is correct, overhead disconnect at 1.5 meters of with down conductor, long flat bar bolt is connected with two connection flat bars.
