AUTOMATIC STATION OF CATHODE PROTECTION OF METAL STRUCTURES AGAINST CORROSION Russian patent published in 2012 - IPC C23F13/02 

FIELD: metallurgy.

SUBSTANCE: station contains nonlinear resistance arresters, a circuit breaker, a power module, a shunt, the first and second sensors of a protective potential, the first and second blocks of comparison, an inverter, the first and second analogue switches, a combiner, power scaling, set point devices of maximum and minimum value of the protective potential, the first and second comparators, a generator, the first and second elements of "И", a bidirectional counter, a digital-to-analogue converter, a current setup unit, a current limiter, a supply voltage sensor, a voltage sensor on the power block, a current sensor, a protective voltage sensor, a door sensor, a cellular modem with a set of data inputs.

EFFECT: increased efficiency of pipeline corrosion protection by automatically adjusting possible deviations of the protective potential values along the pipeline length and maintenance of the protection potential value within tolerable limits.
