摘要
For protecting service personnel during maintenance work on a metal-encapsulated, compressed-gas-insulated high-voltage switching installation, a protective device is provided which is used if gas spaces with voltage-carrying conductor parts are bounded by unilaterally exposed bulkhead bushing insulators. Sensors of the protective device are arranged at the gas spaces and their signals are fed via an evaluating unit to a tripping unit for opening feed switches to cut off the voltage to the conductor elements in the gas spaces as well as for blocking the reclosing of these feed switches.
