Abstract
Provided is a pre-branch grounding electrode. The pre-branch grounding electrode comprises a rectangular frame formed by a folded metal bar; four branch connecting bars stretching upwards are arranged on four corners of the rectangular frame; the lower ends of the branch connecting bars are in welded connection with the rectangular bar and one installation hole is arranged in one upper end; and a stainless steel layer is wrapped around the folded metal bar forming the rectangular frame and the branch connecting bars, and a conductive graphitic layer is wrapped around the stainless steel layer. Compared with the prior art, the pre-branch grounding electrode is advantageous in that: the pre-branch grounding electrode is good in design, simple in structure, easy to manufacture and low in cost, greatly improves the corrosion resisting and conductive performance, effectively prevents hazardous substances such as acids, alkalis, salts in soil from corroding a ground grid, and considerably improves thunder and lightning conduction ability; and construction is easy to carry out.
Description
Technical field
The utility model relates to the lightning protection electrode, is specifically related to a kind of pre-branching type earth electrode.
Background technology
In the power circuit system, ground connection performance quality and the reliability of lightning protection electrode directly affect the normal effectively operation of electric equipment, line facility.At present, existing earth electrode mostly is by smooth bar and is welded to form at the scene, and it has the surface and rust corrosion can occur, come off, and causes the defectives such as earth strip fracture, and have a strong impact on thunder and lightning and derive effect, and site operation difficulty relatively.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of pre-branching type earth electrode is provided.
Its technical scheme is: comprise the rectangle frame that is converted into by metal bar, be provided with upwardly extending four branch's pitmans in four bights of rectangle frame, the lower end of branch's pitman is welded to connect on rectangle frame, and its upper end is provided with installing hole.
Describedly be converted into the metal bar of rectangle frame and the structure of branch's pitman is at the external one deck stainless steel layer that is enclosed with of metal bar, the stainless steel layer outer wrap has the electrically conductive graphite layer.
The utility model has the following advantages compared with prior art: reasonable in design, simple in structure, be easy to produce, with low cost.It has increased the effect of anticorrosion conduction greatly, has effectively completely cut off the erosion of the harmful substances such as the acid in the soil, alkali, salt to ground network, the derivation effect and the easy construction that have greatly improved thunder and lightning.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the schematic cross-section of the utility model metal bar and branch's pitman.
Embodiment
With reference to Fig. 1-Fig. 2, a kind of pre-branching type earth electrode comprises the rectangle frame 1 that is converted into by metal bar, is provided with upwardly extending four branch's pitmans 2 in four bights of rectangle frame 1, the lower end of branch's pitman 2 is welded to connect on rectangle frame 1, and its upper end is provided with installing hole 3.The structure of the described metal bar that is converted into rectangle frame 1 and branch's pitman is at metal barred body 4 and is wrapped with one deck stainless steel layer 5, and stainless steel layer 5 outer wrap have electrically conductive graphite layer 6.
During construction, at first this device is imbedded and will be set up the underground of transmission tower, when set up transmission tower set up finish after, branch's pitman 2 of this device be fixed on the transmission tower by installing hole 3 get final product.There is above-mentioned as can be known the utility model greatly to increase the effect of anticorrosion conduction, effectively completely cut off the erosion of the harmful substances such as the acid in the soil, alkali, salt to ground network, the derivation effect and the easy construction that have greatly improved thunder and lightning.
