GAS-INSULATED SWITCHGEAR DEVICE WITH OPTICAL CURRENT SENSOR

摘要

A gas-insulated switchgear device comprises a current sensor and a voltage sensor located at a partition insulator (1). The current sensor comprises a magneto-optical fiber (11) on a flexible carrier strip (2) and can be manufactured separately for being easily mounted to an assembled switchgear device. The current sensor comprises an electro-optical fiber extending radially into the partition insulator (1) and whose ends are embedded in recesses (16) in the bus bar (5) as well as in the metal embracing (3) of the partition insulator (1) for accurately integrating the voltage.
