Switch device, high-voltage circuit breaker, and method for operating the switch device

Abstract

A switching device for a high-voltage circuit breaker includes at least two switches for ascertaining states of apparatuses of the switching device via a monitoring system. The at least two switches are connected together in series and/or in parallel and can be connected together to exactly one input of the monitoring system. A high-voltage circuit breaker includes the switching device and the monitoring system, which is and/or includes a data acquisition, data processing, data storage and/or data transmission unit, in particular with digital-analog and/or analog-digital converters. A method for operating the switching device provides the at least two switches connected in series and/or in parallel, and forwards the state of the apparatuses via an input, in particular via exactly one input of the monitoring system, in the form of electric variables, in particular a voltage.
