Rectifiers of electrodrainage protection UEDZ are intended for protection of steel underground constructions in a zone of passage of ways of the electrified rail transport by change of distribution of a current in system a rail - the ground -- underground construction. Rectifier UEDZ-A OPE 1,8 У1 differs from the polarized drainage devices presence of own source of a direct current and the block of automatic stabilization of protective potential on a protected construction, and as a matter of fact are the combined device combining in automatically rectifier of cathodic protection and the polarized drainage due to special switching of the rectifier's bridge. These drainages allow to increase considerably limits of adjustment of potentials on a underground construction due to inclusion of an additional source of a current in a circuit of a drainage. Automatic amplified{strengthened} drainages UEDZ are irreplaceable at use in operative ranges of several sources of wandering currents when the drainage on a rail network of one of them appears insufficient. The constructive and circuit decisions applied in rectifier UEDZ, completely are similar used in CP rectifiers UKZT. The given factor causes presence of all advantages and features inherent in UKZT:
-
Simplicity and presentation of controls;
-
Unique ergonomic design;
-
Simplicity and safety in operation;
-
Universality and interchangeability of blocks and units of the case;
-
The compact and strong case from sheet steel 2мм;
-
High-quality and proof powder covering of metal details of the case;
-
Small dimensions and weight.
