5) piezometer ring for average electric field, prevent to launch a surprise attack in the side, lays piezometer ring at material feeding arm, discharge arm, equilibrium arm and the electric panel room top steel structure outside frame of big row's rock machine, and material adopts 30 * 3mm copper bar also to make anti-corrosion treatment.
6) lower conductor adopts 50mm
2The insulation multiply is moulded copper cable, and is no less than two.Connection between arrester, piezometer ring and the earth system adopts the heat release welding technique to connect.
Advantage of the present invention is:
1) discharge in advance arrester and row's rock machine same moved further, disposable input cost is less;
2) the protection area is big and do not have a dead angle;
3) average electric field prevents that effectively side direction from launch aing surprise attack;
4) account for and day do not take up an area of, do not influence that the place main equipment moves and vehicle is come in and gone out;
5) earth system is followed row's rock machine and is moved to extend and lay the compound earth mat of favourable formation.
