Abstract

The invention discloses a cathode protection device for controlling multiplexed output by utilizing polarization potential. The cathode protection device comprises a case, wherein an operation display control unit, an output unit and a multi-path sampling unit are arranged in the case. According to the cathode protection device for controlling multiplexed output by utilizing polarization potential, a control point potential in the area reaches the ideal polarization potential range or polarization potential allowed range, the cathode protection effect of each point can be accurately reflected and guaranteed, the cathode protection device is not required to be adjusted and output, the adjusting steps are greatly simplified, the adjustment complexity is reduced, the reliability of the equipment is improved, the equipment is high in stray current interference resistance, the sudden power change is avoided, and the equipment outputs the constant output current according to a contact current mode, so that the equipment stably operates compared with a potentiostat, the potential adjustment response is reasonable, safe and effective operation of the equipment is guaranteed, the failure rate of the equipment is reduced, the temperature factors are quoted into the adjusting mechanism, and the control precision of the equipment is improved.

Description

technical field [0001] The invention relates to a corrosion protection device, in particular, a cathodic protection device which uses polarization potential to control multiple outputs and its working method, which can be applied to the corrosion protection of metal structures buried in the ground, underwater and in concrete. . Background technique [0002] With the development of the economy and the construction of cities, the number of buried, underwater and concrete metal pipes and metal facilities is increasing, and these metal pipes and metal facilities are prone to corrosion. Cathodic protection is one of the main methods of corrosion prevention at present. , the cathodic protection device is the key equipment of the cathodic protection system. For buried metal pipelines and metal equipment with a large area and high distribution density, regional cathodic protection is required. [0003] When the existing potentiostat is used in the regional cathodic protection envi...
