Abstract

The utility model discloses a shielding-type grounding module which is made of a graphite material; and a grounding module body is internally provided with a metal plate in a way of die-casting, and the metal plate passes through the graphite grounding module. After the technical scheme is adopted, the grounding module body made of the graphite material is used, so that the shielding-type grounding module has the function of reducing the resistance; furthermore, the metal plate has a shielding function; and a first connector and a second connector which are matched with each other are arranged, so that welding does not need to be carried out, and the technical effect of connection can be realized by directly splicing the first connector and the second connector freely.

Description

A kind of shield type earthing module

Technical field

The utility model relates to a kind of earthing device, is a kind of voltage levels transformation facility, military applications, intelligent building etc. exist shielding and ground connection double requirements to power cable shield type earthing module that is used for specifically.

Background technology

Traditional earthing module is made by graphite material, and the extraction electrode that supplies to be welded to connect usefulness is left at two ends, only is used to be not easy to the ground connection environment of vertical junction ground body construction, reaches the effect that reduces earth resistance by horizontally embedded mode.This earthing module exists drawback:

1, function singleness: traditional earthing module only has ground connection and falls the resistance function and do not have any shield effectiveness, and not being suitable for has the ground connection of shielding requirements environment.

2, install complicated: traditional earthing module need adopt welding manner to connect, and needs external power supply, and the personnel that need specialty operation certificate operate, and installation process is complicated, does not have power supply then to be difficult to accomplish like the scene and installs.

3, shielding measure is difficult to realize: when grounding system has desired the time shielding measure, the general employing worn metal tube and then reached shielding requirements with the mode of earthing device welding.

And for a system that has built up, the quantities of so required consumption of measure is huge, and needs whole system is transformed, and therefore almost is difficult to realize.

The utility model content

The purpose of the utility model is; The environment that power cable is existed shielding and ground connection double requirements to voltage levels transformation facility, military applications, intelligent building etc.; A kind of simple possible is provided, the reached shielding of external power source and the earthing device of ground connection double requirements need be provided.

It is following that the utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of shield type earthing module, said earthing module is made by graphite material, and the die casting of said earthing module body interior has the metallic plate that runs through said graphite earthing module.

Further, preferred construction is that the two ends of said earthing module are respectively equipped with first connector and second connector of working in coordination.

Further, preferred construction is also to be provided with the center threaded connection hole that supplies earth connection to connect usefulness at the middle part of said earthing module.

Further, the invention also discloses a kind of shield type earthing module, be formed by connecting a plurality of shield type earthing modules.

The utility model has been taked after the technique scheme, because it has used graphite material to make the earthing module body, thus, has the resistance of falling function; And said metallic plate has function of shielding; And, owing to be provided with first connector and second connector of working in coordination, need not weld, directly through above-mentioned first connector and the technique effect of second connector assembly unit free of one another with regard to realizing being connected.

Description of drawings

Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.

Fig. 1 is the sketch map of the utility model shield type earthing module;

Fig. 2 is the generalized section of the utility model shield type earthing module.

Embodiment

Come the utility model is carried out detailed description below in conjunction with accompanying drawing and specific embodiment.

Fig. 1 is the sketch map of the utility model shield type earthing module; As scheme saidly, said shield type earthing module mainly comprises earthing module body 2 and is located at earthing module body 2 inner metallic plates 1 and forms; And said metallic plate 1 is through said earthing module body 2.

Wherein, said earthing module is made by graphite material; And, be respectively equipped with first connector 32 and second connector 31 of working in coordination at the two ends of said earthing module body 2.

And said first connector 32 and second connector 31 are processed by preforming.

Wherein, also be provided with the center threaded connection hole 4 that supplies earth connection to connect usefulness at the middle part of said earthing module.

Shielding of the utility model and grounding function are mainly realized through following process: use graphite material making earthing module body to be grounded and fall the resistance function.Utilize the metallic plate of earthing module body interior die casting to realize function of shielding.

In addition, said earthing module can be formed by connecting between a plurality of modules, and for example, the connection of said earthing module need not provide external power source to weld, and uses the preforming jointing to carry out free assembling combination and connects.

It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection range of the utility model.

It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection range of the utility model is limited claim and equivalent thereof.
