Method and apparatus for operating with commutation fault protection a commutation installation composed of several commutation fields, in an electric energy distribution network

摘要

It is proposed to generate a digital operating status image in each switching field (1-4) with the command inputs and the switch position signals (SME, SMA), to send this to a collective memory (BSP) arranged in the dome field, which creates an overall image of all switching fields and then there sends to the individual panels at periodic intervals. The locking test is then carried out in the individual panels with this overall picture. Microprocessors (BSP, SFP) are used for implementation. The data exchange takes place on serial 1-bit wide transmission paths (D2-D4). The previously common interlocking wiring harness in the control panel and the cross-wiring between the control panels are no longer required.
