Signal coupling apparatus for communication by medium voltage power line

摘要

A signal coupling apparatus for communication by a medium voltage power line comprises a housing with an inner cavity; an electrode formed on one edge of the housing, one end of the electrode connected to an external medium voltage lead line; a coupling capacitor formed within the cavity and connected to the other end of the electrode; a drain coil formed within the cavity and connected to the coupling capacitor; a power-sided ground terminal formed on one edge of the housing, one end of the ground terminal connected to the drain coil and the other end of the ground terminal connected to a ground terminal of a power system; and a communication-sided connection terminal formed on one edge of the housing, one end of the connection terminal connected to the coupling capacitor and the other end of the connection terminal connected to an external communication equipment.
