Brief history of our products evolution:
– Development and start of manufacture of the first CP rectifiers with manual step adjustment of parameters UKZ-1.
– Development and start of manufacture thiristors CP rectifiers with manual adjustment of parameters UKZT-1.
– Start of manufacture of diode-resistors blocks BDR-25.
– Development and start of manufacture of automatic CP rectifiers UKZT-A
– Development and start of manufacture of automatic rectifier of electrodrainage protection UEDZ.
– Development and tests connection of CP rectifiers UKZT-A to systems of the telemetering control and management.
– Development and the beginning of manufacture of the pipe finder complete set TIA-1000
– Development and start of manufacture of the capacity-inductive filter for CP rectifiers FPP-1
– Development and start of manufacture of not polarized (copper-sulphate) permanent reference electrodes of comparison ESMS.
– The beginning of manufacture of the nomenclature of the equipment on the electro-mechanical factory of JSC « Donskaya korona».
– Modernization of the pipe finder complete set TIA-1000.Is increased sensitivity the receiver in a mode of definition of places of damage of isolation;
– Complex modernization of CP rectifiers of series UKZT. The design is changed and temperature characteristics of the power transformer are lowered, the circuit of protection from overloads, the design of the case and lock’s mechanism is modified, protection of the electronic block of management is increased and its element base is modernized.
– Development and start of manufacture of CP rectifiers “Don-U ” (UKZT-1U, UKZT-AU).
– Development and start of manufacture of the automatic low power CP rectifier “Don-S”.
– The new design of smoothing filter FPP-1 that has made its more functional, and service of the filter – more convenient;
– The block of smooth start is included in a base complete set of all CP rectifiers “Don” and “Don-U”.
– Producing of the new type of an junction boxes – single cannel diode-resistors block BDR-10-1M Y1;
– Producing of the special chassis for CP test station SKIP-102-2,4 intended for mounting junction boxes BDR-25 on it;
– Changing design connection panel and commutation box of the CP test station SKIP-102-2.
– Together with SPE Turbotron Ltd. began creating a telemetry system for cathodic protection rectifiers. The system include terminal software and controllers of remote objects;
– Realized pilot project of the telemetry system on the CP rectifiers UKZT type in Perm Region of Russia;
– The CP telemetry system named “STEL-K”.
– The start of industrial operation the system STEL-K in Rostov Region by GSM communication;
– Start producing the CP rectifiers UKZT-TM with the “KATRON-1” controllers. The rectifiers are integrated to the “STEL-K” system and have functions full remote control.
– The start of industrial operation the system STEL-K in Voronezh Region. The quantity of the mounted CP rectifiers with telemetry is more 200 objects.
– Start producing the CP rectifiers UKZT-TM “TELUR” modification.
– Together with SPE DonKont Ltd. began creating a new generation of the controllers “KATRON-SKZ” for CP rectifiers. The “KATRON-SKZ” has full compatibility with previously modification controllers “KATRON” and “UNIKONT” series and may be integrated to other SCADAs by universal Modbus RTU protocol;
– Created department of field work groups for execution of mounting, starting and adjusting works of the CP equipment and telemetry system, for conducting research and training activities.
– Start producing the multichannel CP rectifiers UKZT-AU OPE MK.
– Start producing of new modifications of the reference electrode ESMS (CuSO4): the portable version ESMS-P and version permanent reference electrode for dry ground ESMS-A;
– Start producing the universal control block “SM-SKZ-TM” for single phases rectifiers. This block may be applyed as reserve block for the CP rectifiers UKZT-TM and others.
– Start producing additional specifications “PS”, “PN” and “Hybride” of the CP rectifiers UKZT-TM;
– Realized the intelligent control algorithm in firmware of the “KATRON-SKZ” for the CP rectifiers UKZT-TM.
– Start producing the brend name CP rectifiers “Don”. CP rectifiers “Don”, “Don-U” and “Don-TM” models have more types of complectation and functions;
– Intelligent control algorim realized on the CP rectifiers “Don” and “Don-U” without controllers “KATRON-SKZ”.
