METHOD AND DEVICE FOR SWITCHING ERROR-PROTECTED OPERATION OF A SWITCHGEAR CONSISTING OF MULTIPLE SWITCHING PANELS IN AN ELECTRICAL POWER DISTRIBUTION NETWORK

摘要

In order to solve the interlocking task in devices for panel-interlocking in the switchboard panels of a switchboard plant, information is required on the states (switching states, earthing etc.) of the other parts of the plant. These states can be detected in a model of the plant and can be interrogated from there. The invention proposes that, as a model, each busbar system (SSI, SSII) of the switchboard plant be provided with a bus system (BI, BII) on which the states of all the switchboard panels (SF) are imprinted and from which the required information on states can be interrogated by panel interlocks (FV). Both a passive parallel bus system and a serial bus system are suitable as the bus system (B). IMAGE
