A) Electrical equipment and accessories power supply, control cabinet, cable, electrical insulation device, electrical insulation protection device. Power supply is to provide the current source for the system, the main constant current, constant voltage rectifier, potentiostat; The control cabinet is the current control system; The cable is mainly a control cable; Electrical insulation device and electrical insulation protection device are current protection devices of the system to prevent current loss.

B) auxiliary anode, coke (carbon) filler auxiliary anode is divided according to the medium. There are scrap steel, ferrosilicon, graphite, mixed oxide anode and flexible anode in the soil. There are mixed oxide anode, silicon iron anode and lead anode in the water medium.

C) Reference electrode The electrode used for reference comparison when measuring the potential of various electrodes. The electrode to be measured and the reference electrode to which the exact value of the electrode potential is known are formed into a cell, and the electromotive force of the cell is measured, then the electrode potential of the measured electrode can be calculated. Reference batteries mainly include: reference electrodes are mainly long-life saturated copper sulfate reference electrode, high purity zinc reference electrode, silver/silver chloride reference electrode, molybdenum dioxide reference electrode. The reference electrode of saturated copper sulfate and high purity zinc can be used in soil, and the reference electrode of high purity zinc and silver/silver chloride can be used in water.

D) Test device potential test pile, current test pile and protection effect test sheet
