FIELD: electricity. ^ SUBSTANCE: multi-channel cathodic protection station includes one power transformer the primary winding of which is connected to the supply voltage source through smooth actuation device. Power transformer includes several secondary windings (according to the number of the station channels) which are connected to the appropriate direct current rectifiers-stabilisers. Each rectifier-stabiliser is connected by means of negative output to its cathodic protection object, and by means of positive output - to anodic earth conductor, and by means of control input - to protective potential sensor. Besides, rectifiers-stabilisers transmit the information on their operation to input-output modules and then to the receiving-transmitting module of telemetry system. ^ EFFECT: improving reliability and safety, as well as providing ease of maintenance. ^ 3 cl, 1 dwg |
