Furthermore, the inner side of the clamp is provided with anti-skid lines.
Furthermore, the material of montant, horizontal pole, clamp and earth bar is copper.
Furthermore, the sacrificial anode is made of magnesium-aluminum alloy.
Further, the ground rod is provided with an external thread, and the sacrificial anode is provided with an internal thread; the grounding rod is connected with the sacrificial anode through threads.
Furthermore, the length of the grounding rod is 2.0-2.5 m.
Further, the number of the cross rods is 1-4.
The utility model discloses a theory of operation does: when the grounding device is installed, the sacrificial anode is fixed on the grounding rod, then the grounding rod is installed on the hoop and is fixed through the fixing bolt and the fixing nut. And finally, burying the grounding device underground, exposing one end of the vertical rod, and connecting the transformer with the connecting hole of the grounding device through a wire. After the sacrificial anode is used for a period of time and is corroded in a large area, soil above the conductive rod can be dug, the conductive rod is taken out by loosening the fixing bolt and the fixing nut, and the sacrificial anode is replaced for continuous use.
The utility model has the advantages that:
the utility model discloses a set up sacrificial anode, form galvanic cell with the conducting rod, can solve the easy problem of corroding of underground conductor part effectively. The utility model discloses set up the conducting rod into having the external screw thread, can use with having the internal screw thread sacrificial anode cooperation, when convenient the change, also reduced the usable floor area of device.
