Abstract
The utility model provides a grounding bar, and belongs to an electric power used component. The grounding bar is provided with an electric conductor, and an insulating bush is arranged outside the electric conductor. Due to the presence of the insulating bush, the electric conductor is no longer exposed outside, the grounding bar is well protected, and the creepage phenomenon is not easy to occur; in addition, the grounding bar has the advantages of certain function of theft prevention and high security when in use; and the service life is long because the electric conductor is not easy to be corroded under the corrosion preventing action of the insulating bush.
Description
Technical field
The utility model provides a kind of electric power parts, especially a kind of earth rod.
Background technology
Usually have earth rod to link to each other with the zero line of power equipment on transformer and other electric power, power consumption equipment, the lower end of earth rod is connected in underground, to improve the fail safe of electricity consumption.Existing earth rod is generally made with whole flat iron bar or flat copper as electric conductor, is directly exposed to the outside, easily is corroded, and useful life is short, is prone to leaky, and easily stolen, and the fail safe of use is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of earth rod, to improve the fail safe of its use.
The utility model is achieved in that earth rod, and it has electric conductor, in described electric conductor outside insulating case is arranged.
Adopt the earth rod of said structure, because the existence of insulating case, electric conductor plays a good protection outside no longer being exposed to; be not prone to leaky, and have certain antitheft effect, use safe; insulating case also plays antisepsis, and electric conductor is difficult for being corroded, long service life.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the top plan view of Fig. 1.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, the earth rod of the utility model, it has electric conductor 3, in described electric conductor 3 outsides insulating case 2 is arranged.
During use, the zero line of electric power such as the upper end of electric conductor and transformer, power consumption equipment links together, and the lower end links together with the joint that is embedded in underground conduction.
Described electric conductor 3 is made of last electric conductor 3-1 that fuses and following electric conductor 3-2.
Described electric conductor 3 two ends are exposed at the outside of insulating case 2.Can improve like this its with the zero line of equipment and underground joint between the convenience that is connected.
There is wiring hole 1 upper end of described electric conductor 3.Can further improve the convenience that is connected between the zero line of earth rod and equipment like this.
Described upward electric conductor 3-1 is a flat copper, and following electric conductor 3-2 is a band iron.Can realize that like this transition connects.
Described insulating case can adopt glass-reinforced plastic material to make, and its outer surface can scribble fluorescent paint, to improve the identifiability at night.
Claims (5)
1, earth rod, it has electric conductor (3), it is characterized in that, in described electric conductor (3) outside insulating case (2) is arranged.
2, earth rod as claimed in claim 1 is characterized in that, described electric conductor (3) is made of last electric conductor (3-1) that fuses and following electric conductor (3-2).
