Automatic cathodic protection transformer rectifiers Don of the UKZT-AU-OPE TM-GSM N1 series, with high energy efficiency, equipped with a control and telemetry controller, are manufactured according to TU 3415-003-27191815-2014 and are designed to protect underground metal structures (pipelines) from electrochemical corrosion using the cathodic polarization method, including in areas affected by stray currents. The CP TRs of this modification have extended functionality due to the use of the KATRON-SKZ controller as a control unit, which implements the basic functions of automatic cathodic protection rectifiers and allows for remote monitoring and control of the operating modes of the CP TRs via wireless communication channels of the GSM (CSD)/GPRS standard or a wired CAN/RS-485/RS-422 interface (Mudbus RTU protocol). Also, this one sopport OPC UA tecknologie. In the cathodic protection rectifiers of this modification, the principles of compatibility of switching connections, element base, main blocks and design units with the oldes modifications of the Don family of cathodic protection rectifiers are traditionally observed, which ensures a high degree of maintainability and practically unlimited possibilities for expanding the functionality of the devices. In addition to the basic equipment, these rectifiers can be supplied in various configurations for personal requirements. The serial nominal power range of produced CP TRs: 0.3; 0.6; 1.2; 2.0; 3.0 and 5.0 kW.
Regulatory compliance
The rectifiers comply with the requirements of GOST 9.602-2016 and GOST R 51164-98 (for "KF" configurations); EAEU Declaration of the compliance with the requirements of the technical regulations of the Customs Union "On the safety of low-voltage equipment" (TR CU 004/2011) "Electromagnetic compatibility of technical equipment" (TR CU 020/2011) Certificate of VCS "Gazcert" (configuration "KF")
Work modes
(basic functions)
— manual setting of voltage and current values on the CP TR output without automatic maintenance; — automatic maintenance of a given value of protective potential on a structure; — automatic maintenance of a given value of output (protective) current; — automatic transition to the output current stabilization mode of the CP TR in the event of a break in the measuring circuit of the protective potential, with the magnitude of the stabilized current will be provide the required value of the protective potential; — automatic limitation of the CP TR output current no more than 1.1 Inom. — operation in doubling output voltage mode (switching to double voltage mode is done manually, by switching the secondary windings of the power transformer. For this mode accordable value of the output current is no more than 0,5 Inom).
Telemechanic functions
The parameters of the CP TR (basic functionality), measured and transmitted by the KATRON-SKZ controller via the telemetry system channels: — CP TR's output voltage value — CP TR's output current value — The value of the protective potential on the structure (when connecting the reference electrode) — Readings of the CP TR work hour meter and the protection time meter — Electricity meter readings — AC Power Supply Voltage Values — State of the security alarm sensor of the cabinet door CP TR — Information about the set mode, sub-mode of operation and setting value — Controller backup power supply battery charge voltage — Broadcasting of alarm and emergency signaling messages (to the control post and duplication of messages in SMS format to the mobile phone of registered staff) — Controller real time clock status — Actual configuration of the controller settings and the current version of the control software. Remote control: — Setting the operating mode of the CP TR — Setting the submode of operation of the CP TR — Setting the setpoint for the submode — Configuring the controller Service functions: — Transfer of current parameters of the CP TR upon request from a mobile phone in SMS message format (provided that the administrator of the telemetry system provides a telephone number registration in the settings of the controller)
Service functions
— Electronic recorder function with 1 hour recording sampling of average values (data storage depth - 2 months). The data is stored in the non-volatile memory of the controller and can be retrieved remotely — Supports registration of up to 4 phone numbers for sending alarm messages and monitoring current parameters — Automatic detection of equipment/system failure and selection of emergency operation mode (intelligent control function) with corresponding indication of the failure type.
