Abstract
A grounding electrode comprises a main body and a wire connecting terminal, and is extensively applied to the temporary power supply systems of low-voltage distribution networks and construction sites. The main body comprises an upper part, a middle part and a lower part, and adopts a tubular body; the wire connecting terminal is arranged on the side surface at the upper end of the main body; longitudinal grooves are formed on the outer surfaces at the middle part and the lower part of the main body; small through holes are uniformly distributed in the grooves; and the lower part of the grounding electrode is wedge-shaped. The grounding electrode has the advantages of simple structure, material conservation, convenient operation, portability and reusability, can meet the requirements of national and industrial standards, and can conveniently change the grounding resistance by adding the middle grounding body to meet on-site requirements, thereby improving the running quality of low-voltage alternating-current systems, and guaranteeing the personnel safety of the staff.
Description
Technical field
The utility model relates to a kind of earth electrode that can be applicable to the interim power-supply system of low voltage power distribution network and construction site, particularly a kind of neutral point (line) ground connection that is widely used in the low-voltage alternating-current earth neutral system, equipment ground in the isolated neutral system.
Background technology
According to the regulation of national standard and power industry standard, the earth resistance of equipment protection ground connection must not be greater than 10 ohm in the neutral ground of low-voltage alternating-current earth neutral system and the isolated neutral system.
Present low voltage power distribution network is the low-pressure system of construction site particularly; specification, the quality of transformer neutral point ground connection, distribution box neutral line iterative earthing and device housings protective earthing materials used are not quite similar; grounding resistance is difficult to satisfy country and industry standard; the earth electrode poor operability is unfavorable for reusing and storage is carried.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of earth electrode simple in structure, portable, easy-operating, reduce earth resistance, improve the ground connection reliability, satisfy the service requirement of on-the-spot low-voltage alternating-current system, further guarantee staff's personal safety.
The technical scheme that solution the utility model problem is taked is: it is made up of earth electrode main body and binding post, and the earth electrode main body is a tubular body, and binding post is located on the upper side of earth electrode main body; The middle part of earth electrode main body and lower external face are provided with groove longitudinally, are evenly equipped with penetrating aperture in the groove; The bottom of earth electrode is " wedge " shape.
For being convenient for carrying, the top of earth electrode main body, middle part and bottom are formed by three sections, between each section by being threaded.
For the ease of loading and unloading, symmetry respectively is provided with a plane on the outer surface of top, middle part and the bottom of earth electrode main body.
Good effect of the present utility model is: simple in structure, save material, and operate easy to carry, reusable; Can satisfy country and the requirement of industry standard regulation, can change earth resistance easily, satisfy on-the-spot needs, improve the running quality of on-the-spot low-voltage alternating-current system, assurance staff's personal safety by increasing the method for middle part earth electrode.
Description of drawings
Accompanying drawing 1 is a schematic diagram of the present utility model; Accompanying drawing 2 is that accompanying drawing 1A-A is to cutaway view.
Embodiment
The utility model is shown in accompanying drawing 1,2, it is made up of earth electrode main body and binding post, the earth electrode main body is made up of top 2, the 11 3 sections tubular bodies in middle part 4 and bottom, make by hot galvanizing steel tube type material, binding post 1 is located on 2 upper side of earth electrode main body top, can directly compress lead and various line nose; Be equipped with groove 6,9 longitudinally on the middle part 4 of earth electrode main body and bottom 11 outer surfaces, be evenly equipped with penetrating aperture 7,10 in the groove 6,9, long-pending to increase with soil contact; The bottom 11 of earth electrode is " wedge " shape, is convenient to by external force earth electrode be inserted in the soil.For the ease of loading and unloading, symmetry respectively is provided with a plane 3,5,8 on the outer surface of top 2, middle part 4 and the bottom 11 of earth electrode main body, when storing or carrying, earth electrode can be decomposed, and saves the space.
