Device for the connection of insulating gas between two adjacent cells of an encapsulated electrical switchboard, in which the cells contain on their interior an insulating gas and are passed through in a tight manner by flanged lead-throughs which house the conductor for the electrical connection. The device is accommodated inside the flange of a lead-through and consists of a metal body with two passageways for the gas, each connected to a cell, and an element, which can be controlled from the outside, to place said passages in communication with one another or to close them both. The controllable element consists of a screw, the head of which protrudes on the outside of the flange and is sealed by a cap with a seal. |
