In high-voltage installations with metal casing and compressed gas insulation, housings (1, 7) whose longitudinal axes are mutually inclined must often be interconnected via an intermediate piece (8). The intermediate piece (8) consists of two rings (19, 20) whose front faces are in contact. Each ring has holes (22, 32, 23, 33) on an inner (21) and an outer (31) graduated circle. The two rings are connected to the flange (9, 10) of the housing at their respective graduated circles (21) and to each other at their respective outer graduated circles (31). The spacings beta i, beta a of the holes on the two graduated circles are different and chosen so that in each case their sum is 90 DEG or 60 DEG . On one ring (20), the holes (32) on the outer graduated circle (31) are elongated holes (32) the length of which is given by angle gamma = beta i. beta a/90 DEG or beta i. beta a/60 DEG . The intermediate piece (8) makes it possible to set the angles +/- alpha between the longitudinal axes to any value in the range +/- 90 DEG or +/-60 DEG . |
