Abstract

The utility model discloses an earth mat, wherein, the surface of the earth mat (1) connected with an electrolytic anode plate (3) is provided with an antisepsis conducting film. Accordingly, the earth mat with the structure overcomes the problems of an existing earth mat and can carry out functions thereof without considerations of seasonal variation and edaphic erosion. The utility model has the advantages that the surface of the earth mat do not scar, the service life is long, the value of a ground resistance is smaller than the value of a normal ground resistance during the life time, etc.

Description

A kind of ground network

The utility model discloses a kind of ground network of new structure.

At present, round steel that ground network is normally selected for use by designing requirement routinely and angle steel are welded, buried underground, because the effect of ground network is that the staff has the danger of electric shock when preventing insulation of electrical installation destruction, or provide electric equipment normal operation face to need the working earthing of certain point; Therefore, the grounding resistance of ground network must be less than the specified standard value.But because the corrosion of seasonal variety and soil, grounding resistance often is higher than the standard grounding resistance, in order to address this problem, people increase earth electrode to ground network every year, or increase that it is buried, or watering, but still can not long term maintenance, and have blindness; In addition, the people is also arranged at the ground network place, dose bentonite, gypsum and sodium sulphate mixture though reduced resistance, have strengthened the corrosion of ground network.

The purpose of this utility model provides a kind of ground network of new structure.

The purpose of this utility model is achieved in that a kind of ground network, and the anticorrosion conducting film of one deck is arranged on the surface of ground network, is connected to the sacrificial anode plate on the ground network.

Wherein, ground network surface area: sacrificial anode plate surface area=(25～15): 1

The utility model has the advantages that: touched the anticorrosion conducting film of one deck owing to being coated with on the surface of traditional ground network, on ground network, connect the sacrificial anode plate again, thereby make ground network can not have its due effect because of the corrosion of seasonal variety and soil, do not scab in ground network surface with this structure, long service life can guarantee that in useful life grounding resistance is lower than the standard grounding resistance.

Fig. 1 is the local enlarged diagram of the utility model;

Fig. 2 is the utility model structural representation;

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment 1:

A kind of ground network 1 has one deck corrosion-resistant conductive coating on the surface of ground network 1, forms anticorrosion conducting film 2.

On ground network 1, welding sacrificial anode plate 3, also available VV29 of sacrificial anode plate 3 or XV29 lead 4 are connected on the ground network 1 the ground network surface area: sacrificial anode plate surface area=(25～15): 1, or (23～17): 1, or (21～19): 1, or all can at 20: 1.

Sacrificial anode plate 3 is zinc-base, aluminium base, magnesium base.

The anticorrosion coating 2 of leading is exclusively used on the ground network.
