US 8,710,364 B2 · Multiple angle bend for high-voltage lines

Abstract

The bend of the invention makes it possible to provide a great number of different direction changes in the configuration of gas-insulated high-voltage lines. The bend mainly uses an angled ferrule (11). associated with two angular rings (12), placed between the angled ferrule (11) and a straight section (13) of the line, each angular ring (12) forming a change of direction defined by a determined angular offset angle (α) between said two joining surfaces. Thus, the use of an angled ferrule (11), in combination with one or two angular rings (12) makes it possible to obtain the four angular offsets of 70°, 80°, 100°, 110°. These same angular rings (12), used with an angled ferrule having an angle of 140° makes it possible to obtain the angles of 120°, 130°, 150°, and 160°. Use for constructing gas-insulated high-voltage lines.

Dependent claims

A direction-changing bend for a high-voltage line of the gas-insulated type, the line comprising:

two straight sections each composed of:
a tubular conductive bar (19);
and
a confinement ferrule (13) surrounding the conductive bar (19);
and
an angled ferrule (11, 21);
the bend being characterized in that it includes two angular rings (12) each designed to be interposed between the ferrule (11, 21) and one of the two conductive bars (19) with its respective confinement ferrule (13) via two connection surfaces, a first connection surface to be fastened on the angled ferrule (11, 21) and a second connection surface to be fastened on a corresponding conductive bar (19), each of the first and second connection surfaces being in a respective plane that is angularly offset from the other plane by a determined angle (α).
