FIELD: electrical engineering; power-station and substation switchgear installations.
SUBSTANCE: proposed device has switching apparatus position detectors, interlocks on operating mechanisms, and electromagnetic switch; newly introduced in device are receiver and logic circuit. Position detectors are contactless units incorporating nonmagnetic plastic pointer and wireless reed-relay transmitters. Each output of receiver unambiguously relates to continuous coded radio signal of each wireless reed-relay transmitter. Inputs of logic circuit are connected to receiver outputs and outputs, to interlocks. One of receiver outputs unambiguously relates to continuous coded radio signal of wireless reed-relay transmitter of electromagnetic switch and is used for remote connection of logic circuit to power supply.
EFFECT: enhanced operating reliability and reduced maintenance and early-failure charges.
