Band, the bottom of the soft graphite base band is equipped with the water pipeline symmetrical with lateral main line and longitudinal main line, described to send water
The two sides of the bottom of pipeline offer a discharge water hole respectively, and water pump, the outlet end of the water pump and institute are provided in the pond
State the arrival end connection of water pipeline.
As a kind of further improvement of substation grounding device described in the utility model, the vertical grounding electrode and cross
It is connected between line main line and longitudinal main line by lead.
As a kind of further improvement of substation grounding device described in the utility model, the controller is PLC control
Device processed, and the water pump and moisture probe are electrically connected with controller.
As a kind of further improvement of substation grounding device described in the utility model, the transverse direction main line and longitudinal direction
Main line is made of compound copper-made grounding device.
As a kind of further improvement of substation grounding device described in the utility model, the transverse direction main line and longitudinal direction
Infall between main line is welded with cross connecting plate.
Beneficial effect
The utility model by moisture probe to earthing pole carry out Humidity Detection, by water system, endlessly to
It supplies water around grounding body, makes to keep certain humidity around grounding body throughout the year, because graphite-based flexible ground body has water imbibition, inhale
The conductivity that water energy increases grounding body is received, due to the certain moisture of the soil conservation around grounding body, makes grounding body and the earth
Conduction is more preferable, and ground resistance is lower, when lightning current is easier by grounding body, faster spills into the earth, it is possible to reduce apply
Work cost, the long-term stabilization for ensureing earthed system to graphite counterpoise grounding and are drawn online connection using nonmetallic fixture, are more accelerated
Victory is convenient, and compound copper-made grounding device is that connecting body surface face is covered with carbon nano conductive adhesive, protects copper not to be corroded well.
