ANODES WITH MONOLITHIC PRE-PACKING, NOVEL CATHODIC PROTECTION SYSTEM THAT SAVES ELECTRICAL ENERGY AND INCREASES THE USEFUL LIFE OF SAID ANODES

摘要

The invention relates to a cathodic protection system based on impressed current. According to the invention, the anodes, which constitute the positive current diffusers in the system, are altered in terms of the standard structure thereof using a monolithic electroconductive material and a series of internal arrangements which cause a reduction in the electric resistance to the passage of current in an anodic device. In this way, power requirements are reduced, a considerable saving is made in relation to electrical energy and the useful life of said type of anode is increased. The configuration of the novel anode does not alter the electrochemical phenomenon intrinsic to cathodic protection. Said configuration is based primarily on the use of standard and commercial anodes in the form of an anode-core (4). The aforementioned anodes are pre-packed in a mixture of chemical compounds (2) which, through the addition of water, form a larger, heavier monolithic anode which can operate in both the vertical and horizontal positions. Moreover, said anodes can be used on sandy surfaces as well as in swamps, marshes and marine areas.
