Abstract
The utility model relates to a meshy electrical equipment earthing body and solves the earthing problem in volcanic and desert regions with high geological soil resistivity. The meshy electrical equipment earthing body comprises a meshy earthing body and one or more earthing outgoing wires. Compared with a bar-type earthing body, because the earthing body is of a meshy shape, the contact area is increased, and the contact resistance is reduced so that the meshy electrical equipment earthing body is suitable for environments with high soil resistivity; and compared with a plate-type earthing body, materials are saved. The meshy electrical equipment earthing body is made of standard earthing sections and is durable and convenient for realization.
Description
Technical field
The utility model relates to a kind of earth electrode, and specifically, it is a kind of latticed electric equipment earth electrode, is specially adapted to the ground connection of volcanic rock and desert area.
Background technology
The main purpose of electric equipment ground connection be with the earth as the zero potential of electric equipment and safety relief lightning current or other fault current, thereby avoid electronegative potential in the electric equipment to raise and cause equipment and personnel's security incident.Except that equipment and personal security, for electric and robot control system(RCS), the ground connection that can system good can have influence on effective transmission of signal, and therefore, ground connection is very important to the stability of safeguards system operation well.Existing earth electrode commonly used generally is divided into two classes, one class is the bar type earth electrode, one class is board-like earth electrode, a kind of bar type earth electrode commonly used is made of earth electrode rod and a ground outlet of the accurate specification of two feast-brand marks, wherein two joint earth electrode rods are threaded togather, vertically pound during ground connection into underground, described ground outlet level welding or embedded level are connected on the earth electrode rod, as the lead-out wire of earth electrode rod.Earth electrode rod and ground outlet can adopt metal materials such as copper or copper covered steel to make, and wherein are made as the best with the good copper product of conductivity.Board-like earth electrode commonly used is connected and composed by ground connection pole plate and ground outlet, and ground connection pole plate wherein is copper coin, aluminium sheet or iron plate, digs pit during ground connection that it is underground to imbed, and is drawn by the ground outlet level.The ground connection resistance of electric equipment generally requires＜and 4 ohm, electric and electronic equipment shared grounding resistance requires＜1 ohm.Above-mentioned bar type earth electrode is unsuitable for volcanic rock and desert area, because the resistivity height of volcanic rock and desert area geology soil, so cause the contact resistance of earth electrode and the earth to increase, do not reach the requirement of ground connection resistance＜1 ohm, simultaneously, rock ground is too hard, also can't with pound into method construction, cause bigger difficulty to ground connection.Board-like earth electrode is bigger than the contact area of bar type, the method of imbedding with digging pit can be implemented in the ground connection construction in rock area, but because the resistivity height of volcanic rock geology soil, so need to adopt the strong copper coin of electric conductivity, but copper product is more expensive at present, has increased the ground connection cost.
The utility model content
The purpose of this utility model is at the problem in the prior art, and a kind of latticed electric equipment earth electrode is provided, and makes it adapt to the high soil environment of resistivity, can save material simultaneously again and be easy to and make.
For achieving the above object, the technical solution of the utility model is as follows:
It is made of a latticed earth electrode and one or more ground outlet.
The further improved technical scheme of the utility model is as follows:
The square bearer that described latticed earth electrode is surrounded by ground outlet bending of a usefulness and be located at many earth electrodes rods that form the square net line on this square bearer and weld and constitute.
Compared with the prior art the utility model has following characteristics:
One, earth electrode employing of the present utility model is latticed, has increased contact area than existing bar type earth electrode, has reduced contact resistance, makes it be applicable to the environment that soil resistivity is high, and has saved material than board-like earth electrode.
Two, the utility model adopts standard ground connection section bar to make, and is durable in use, be convenient to realize.
Three, latticed earth electrode of the present utility model is convenient to multiple spot and is drawn, and conveniently draws toward a plurality of zones.
Description of drawings
Accompanying drawing, overall structure schematic diagram of the present utility model.
Embodiment
Referring to accompanying drawing, it is made of a latticed earth electrode 1 and one or more ground outlet 2, the square bearer 101 that described latticed earth electrode 1 is surrounded by ground outlet bending of a usefulness and be located at many earth electrode rods 102 that form the square net line on this square bearer.Easy to make for making, the tin-coated copper product of standard specification is preferably adopted in described square bearer 101, ground outlet 2, and earth electrode rod 102 preferably adopts the tin-coated copper earth electrode rod of the accurate specification of a feast-brand mark, and welds together.Like this, not only convenient the making simultaneously, also can utilize the corrosion resistance characteristic of tin to prolong the useful life of whole earth electrode.
When volcanic rock and desert area use, buried method is constructed with digging pit, because latticed earth electrode has increased the contact area with the earth, simultaneously, the copper rod excellent conducting performance is arranged again, thus be easy to satisfy the requirement of earth resistance＜1 ohm, if can't satisfy, can just can meet the demands fully at the end, hole some resistance reducing agents of place mat again.
Claims (2)
1. latticed electric equipment earth electrode is characterized in that: it is made of a latticed earth electrode (1) and one or more ground outlet (2).
2. latticed electric equipment earth electrode according to claim 1 is characterized in that: the square bearer (101) that described latticed earth electrode (1) is surrounded by ground outlet bending of a usefulness and be located at many earth electrode rods (102) welding that forms the square net line on this square bearer and constitute.
