SYSTEM OF SWITCHING EXECUTIVE BODIES WITH NON-DESTRUCTIVE TESTING SWITCHING ELEMENTS AND EXECUTIVE BODIES Russian patent published in 2018 - IPC G05B23/02 

Abstract RU 2652718 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and electronics and can be used as part of a control equipment with power supply with a constant voltage of branched systems of executive bodies for nondestructive testing the executive bodies and elements of their switching. Switching system of executive bodies with non-destructive testing the switching elements and the executive bodies comprises a power supply unit with a positive and a negative power buses of power supply, +E and -E power supply circuits, herewith the negative power bus of the power supply unit and the -E power supply circuit form a common GND bus, power switches connected to the +E and the -E (GND) power supply circuits, the executive bodies connected in series with the power switches; an electric switch of the power supply bus comprising a changeover contact connected to the +E power supply circuit, and a normally open contact connected to the positive power bus of the power supply unit, a control and monitoring unit comprising a control and feedback input and an output control bus, the circuits of which are connected to the control inputs of the power switches, and ±U power supply source of limited power, whose -U circuit is connected to the common GND bus, control resistors and a diode, a measuring device having two input circuits – a potential and a common ones, and an information output. System is also equipped with a current-limiting resistor connected by one terminal to the +U circuit of the ±U power supply source, and by the other terminal – to the +E power supply circuit. Control resistors and diodes are interconnected in pairs in series forming control RD-circuits, which are connected to the power switches outputs connected to the +E power circuit on one end, and on the other end are interconnected and connected to the potential input circuit of the measuring device, the common input circuit of which is connected to the common GND power bus.

EFFECT: as a result, the operational properties are improved and the functionality of the system is extended.
