Control device for electromechanical panels of relay protection and automation

摘要

The utility model relates to the field of relay protection and automation (RPA) and can be used in power plants and substations operating relay protection equipment made on electromechanical relays mounted on panels of insulating material (electromechanical panels). The technical result is an increase in the functionality and information content of the control, a reduction in the time for detection and elimination of malfunctions arising from the operation of electromechanical relay protection and automation panels, and an extension of their service life. The device 1 contains a microcontroller 2, equipped with a data exchange port 4, interfaces 5 and 7 with connectors for discrete and analog inputs 6 and 8, respectively, and an interface module 10. Module 10 contains cable parts 11 of the interface connectors fixed to the microcontroller 2 structure. To the contacts of the cable parts 11 with flexible wires 15 are connected branch clamps 12 and equipped with a split core current transformers 14, designed to be removed directly from the mounting wires 13 of the controlled panel 9 of the voltage and current signals, respectively. The microcontroller 2 is programmed with the ability to register and functional identification of signals recorded by module 10. 2 z.p. f-ly, 1 ill.
