MEDIUM-VOLTAGE ISOLATED CAPACITIVE COUPLING SYSTEM

摘要

The invention relates to a medium-voltage isolated capacitive coupling system comprising a sealed enclosure which houses a medium-voltage capacitor (12) and a shield (17) which is used to distribute the electric field. The aforementioned enclosure is connected to a cable (4) or to a medium-voltage cell (1) with isolation and cut-off provided by means of a gas or another dielectric, using connectors (3) and/or shielded cables (7) which are connected via the bushing (2) of the cell. In this way, analogue and/or digital signals can be transmitted and received via the electric power distribution system while maintaining the isolation and safety characteristics of the transformation centre as well as a high level of protection against environmental conditions.
