Electrical switchgear with a built-in connection system for connecting measuring equipment and injecting and sensing low-frequency and high-frequency signals

摘要

The present invention relates to electrical switchgear with a built-in connection system (7) for connecting measuring and/or communication equipment comprising: at least one high-voltage compartment (1, 1') incorporating electric power distribution elements (2); at least one low-voltage compartment (3) incorporating control, communication, diagnostic, measuring and protection elements (4); and at least one connecting point (6) for measuring and/or communication equipment (5); where the connecting point (6) for measuring and/or communication equipment (5) is installed in the low-voltage compartment (3), such that the measuring and/or communication equipment (5) can be connected without having to perform switching operations in the high-voltage power grid.
