INTELLIGENT DEVICE OF CONTROL OF SWITCHING DEVICES OF ELECTRIC NETWORK Russian patent published in 2014 - IPC G05B13/02 G01R11/25 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of electric measurement equipment, switching control and alarm of condition of a three-phase electric network, namely, to multifunctional multi-rate instruments of electric energy accounting. In the intelligent device of switching devices control in the electric network a relay unit is additionally connected to a microcontroller, and the relay unit is energised from a power supply unit and a reserve power supply source and supplying commands to terminals of switching device control, making it possible to perform, using additional equipment (electric drive, electromagnetic coil), control of switching device contacts, and to independent terminals of reserve control, making it possible to switch the reserve or start the generator, and to an analogue-digital converter an additional unit of voltage sensors is connected, which reads the parameters downstream contacts of the switching device, the non-volatile memory includes the second additional memory register, containing parameters of relay unit operation in case of an abnormal situation.

EFFECT: increased reliability of a communicating device.
