Abstract
Accessory device for a low or medium voltage switching device including an outer housing, first electrical connection means adapted to electrically connect the accessory device with an auxiliary power line and first mechanical connection means adapted to mechanically connect the accessory device with a mechanical support component of the switching device. The accessory device includes a power line communication unit electrically connectable with the auxiliary power line through the first electrical connection means and adapted to communicate with outer electronic equipment electrically connected with the auxiliary power line by transmitting and receiving communication signals along the auxiliary power line.
Claims22
An accessory device for a low or medium voltage switching device comprising an outer housing, first electrical connection means comprising a socket or a plug adapted to electrically connect said accessory device with an auxiliary power line feeding electronic components of an electric power distribution grid, first mechanical connection means including first coupling portions of said outer housing adapted to mechanically connect with corresponding mechanical coupling portions of mechanical support components of said switching device wherein it comprises a power line communication unit electrically connectable with said auxiliary power line through said first electrical connection means and capable of communicating with outer electronic equipment electrically connected with said auxiliary power line by transmitting and receiving communication signals along said auxiliary power line, said communication signals being analog AC signals travelling at high frequencies and overlapped with feeding voltages and currents provided by said auxiliary power line.
An accessory device for a low or medium voltage switching device comprising an outer housing, first electrical connection means adapted to electrically connect said accessory device with an auxiliary power line and first mechanical connection means adapted to mechanically connect said accessory device with a mechanical support component of said switching device wherein it comprises a power line communication unit electrically connectable with said auxiliary power line through said first electrical connection means and adapted to communicate with outer electronic equipment electrically connected with said auxiliary power line by transmitting and receiving communication signals along said auxiliary power line, wherein said power line communication unit comprises a first processing module and a power line interface module operatively coupled with said first processing module and electrically connected with said auxiliary power line, and further comprising an additional processing unit operatively coupled with said power line communication unit, said additional processing unit comprising a second processing module operatively coupled with said first processing module and a bus interface module operatively coupled with said second processing module.
