Abstract
The utility model relates to a long acting flexible grounding electrode which is composed of a metal grounding electrode and a conductive silicon rubber protection layer packaged outside the grounding electrode. Because a conductive silicon rubber protection layer packages outside the grounding electrode, the utility model has no affection the subterranean water, is not easy to be corroded, and has an long-term use.
Description
Technical field
The utility model belongs to a kind of earth connection that is used for the overvoltage protection of subterranean pipe line long lines, particularly a kind of long-acting flexible earth electrode.
Background technology
Earth electrode all adopts shaped steel mostly both at home and abroad at present, and as metal earth electrodes such as band steel, angle steel, steel pipes, this class earth electrode itself just is easy to be corroded; The earth electrode of present new class, as the plasma earth electrode, the conducting solution/compound in its earth electrode is subject to phreatic influence, and degradation failure.
Summary of the invention
The purpose of this utility model provides a kind of not perishable, and is not subjected to the phreatic long-acting flexible earth electrode that influences again, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of the metal earth electrode, is characterized in: the protective layer that is wrapped with one deck conductive silicon rubber at the metal earth electrode.
Because the utility model is wrapped with the protective layer of one deck conductive silicon rubber at metallic object, makes the utility model can not be subjected to phreatic the influence, also is not easy to be corroded, and can use for a long time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The metal ground connection of the utility model earth electrode is multiply copper core twisted wire 1 very, and it is outer to be the protective layer of conductive silicon rubber 2.Conductive silicon rubber 2 protective layers both can conduct electricity, and had to protect copper stranded conductor not corroded, and had good low temperature tolerance ability.
The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
Claims (2)
1, a kind of long-acting flexible earth electrode is made of metal earth electrode (1), it is characterized in that: the protective layer that is wrapped with one deck conductive silicon rubber (2) at metal earth electrode (1).
2, long-acting flexible earth electrode as claimed in claim 1 is characterized in that: metal earth electrode (1) adopts multiply copper core twisted wire.
