Modernization of control actuators and transducers

الوصف

In thyristor converters and, as a rule, the power components (thyristors, reactors, transformers, switchgear and protective equipment) have a service life is several times larger than the electronic devices. Their share in the cost of the product is significantly higher than that of controls. In this regard, cost-effective management is upgrading converters made ​​in ****0., To restore the resource. "Depth" ongoing modernization can range from replacing some blocks (cells) management system to full replacement of all electronic devices (cell control, protection, management, parameter sensors, power supplies, pulse shapers, assistive devices (exciter power supply, power supply, electromagnetic brakes, dynamic brake control) indicating devices, alarm systems, measuring instruments) and replace the wires in the secondary circuit. Given the fact that the recovery of the resource depends on the depth of modernization, the greatest effect brings the most complete modernization, because it is achieved by extending the life of 8 ... *0 years. From the "depth" of modernization and cost depends of work performed, which can range from 5 to *0% of the cost of the converter. For example, if the maximum "deep" modernization of the electric KTE***0/**0 this value is about *0%. Modernization electric modernization drive can be performed using an integrated management system "PROTON" .
