Problems solved by technology

However, this technology does not change the overall control logic of the system and forms a completely independent partition control unit. There are still problems such as high system power, low energy efficiency ratio, low control sensitivity, cumbersome wire and cable layout, and low intelligence of the control system.

Abstract

The invention belongs to the technical field of ship corrosion protection, and particularly relates to a marine impressed current cathodic protection system based on a distributed architecture, which can realize lower equipment power, higher energy efficiency ratio, faster dynamic response feedback regulation speed and more accurate and more uniform ship potential control under the condition of equal current output. The overall weight and energy consumption of the system are greatly reduced, meanwhile, the upgrading of the control terminal enables the control mode to be more intelligent, the functions of zone control and centralized management are achieved, the possibility is provided for upgrading and updating of the ship impressed current cathode protection system, and space is reserved for intelligent upgrading; the structure is simple, the same protection current requirement can be met by adopting electrical equipment with lower power and energy consumption, the dynamic response of'regulation-feedback 'is more sensitive, the potential control and current output are more accurate, and the overall protection potential distribution of the whole ship is more uniform along with the great reduction of the cable arrangement, the great reduction of the total power and the great reduction of the total weight.

Description

Technical field: [0001] The invention belongs to the technical field of ship corrosion protection, and in particular relates to a marine impressed current cathodic protection system based on a distributed architecture, which is suitable for corrosion protection of all large and medium ships. Background technique: [0002] Impressed current cathodic protection system is an essential device for marine ship hull anticorrosion. It has the function of automatically adjusting the protection current with changes in external conditions such as ship speed, sea area, paint damage degree, etc., so that the hull potential is always in the best protection range, so as to protect The underwater parts and appendages of the hull are protected from corrosion by seawater. It is suitable for the mooring and sailing state of ships in seawater, and is mainly composed of a potentiostat, an auxiliary anode and a reference electrode. The basic working principle is to provide direct current through...
