Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 for inspection earthing mechanism 2 for maintenance electric welding machine 3 for earth rod A4 be earth rod B; 5 is earth rod C; 6 is insulated copper heart yearn; 7 is ironware; 8 is copper cash nose; 9 is insulated pliers for pressing hole 10.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
The invention provides a kind of simple and easy ground network apparatus for examination and repair, include inspection earthing mechanism and the maintenance electric welding machine that can keep in repair fault; Inspection earthing mechanism include have grounding function earth rod A, have grounding function earth rod B, there is the insulated pliers of insulation function, on earth rod A and earth rod B, be all provided with ironware, the ironware of the ironware of earth rod A and earth rod B is all crimped with the insulated copper heart yearn with insulation function by copper cash nose, the other end of the upper insulated copper heart yearn connecting of earth rod A is pressed and is connected with insulated pliers by copper cash nose, and the other end of the upper insulated copper heart yearn connecting of earth rod B is connected on the insulated copper heart yearn being connected with earth rod A; On the shell of maintenance electric welding machine, by insulated copper heart yearn, be connected with earth rod C, earth rod C is provided with ironware, and one end of insulated copper heart yearn is by the ironware crimping on copper cash nose and earth rod C; Earth rod A, earth rod B and earth rod C are cylindrical steel, and the Φ of cylindrical steel is 16mm, and the length of cylindrical steel is 80cm, cylindrical steel one end is that pinching degree is 20 aspects, electric conductivity is best, and the pinching end 70cm place apart from cylindrical steel on cylindrical steel is provided with ironware, connects effect best; The thickness of ironware is 20mm, and the length of ironware is 60mm, and the width of ironware is 40mm, and the effect of conduction is best, and connects the most firm; The insulated copper heart yearn total length that earth rod A connects is 10m, and the total length of the insulated copper heart yearn that earth rod B connects is 6m, and the total length of the insulated copper heart yearn that earth rod C connects is 4m, and the radius of insulated copper heart yearn is 5mm; Crimping place of ironware and copper cash nose is provided with presses hole; Pressing the diameter in hole is 12mm, to reducing touch voltage and step voltage, there is the effect of highly significant, the gravitation of earthing device ground connection plumb pile, reduced earth potential, directly touching step voltage all has direct relation (drainage), and most of trouble power flows into the corresponding diffusing amount that has reduced horizontal conductor of the earth by ground network to the vertical utmost point.The maintenance easy device of ground network is provisional, just removes, in case two earth electrodes produce potential difference after ground connection or ground network repair.
