Description
The universal control block SM-SKZ-TM may be used as automatic control block for single phase thyristor’s CP rectifiers (with two controlled thyristors). For first installation of the block this one may be completed by additonal set with external power supply transformer, measuring shunt (75 mV, 100 Amps) and wires with connectors plug for connection to the rectifier’s circuits.
The block is equipped by:
Integrated DC Ampermeter/Voltmeter (range till 100Amps/100 V) Output current/voltage regulator Automatic/Nonautomatic modes switcher Switcher of output current or protective potential automatic stabilization modes. The block provide next parameters and modes:
Rectifier’s output current/voltage control for range from 2 till 100% nominal value; Nonautomatic mode control by rectifier’s output current/voltage Mode of automatic stabilization of the rectifier’s output current for range from 2 till 100% nominal value Mode of automatic stabilization of the protective potential relatively reference electrode for range from –0,5 till -4,5 V Accuracy of stabilization is not less 2,5% Indication of output current and voltage for ranges from 0 till 100 Amps and from 0 till 100 V.
Versatility of application and functionality
- applicated for any single phase rectifier with implementation of control and management functions; - connection directly to power thyristors of the CP rectifier's bridge; - ensuring regulation of the output current/voltage of the CP rectifier in the range from 1 to 100% of the nominal values; - ensure full design and electrical compatibility with KATRON-SKZ controllers, which allows the module to be used as a backup control unit during repair or verification of the main controller.
Regulatory compliance
To implement additional protection against external overvoltages and overloads, the module can be equipped with a removable self-healing module for protecting measuring circuits and power supply circuits "Barrier KATRON-SKZ". To facilitate connection to third-party CP rectifier, the module can be supplied complete with a universal electrical harness, measuring shunt and supply transformer.
Advantages
— the ability to connect to any single phase cathodic protection rectifier as a control and automation unit; — possibility of direct connection to power thyristors of the rectifier bridge CP TR for direct regulation of output voltage/current.
