During the assembly of the switch pole (10), the individual parts (12, 14, 20, 24, 30) of the housing (36) are loosely stacked one on top of the other and fixed. This can be done by application of a partial vacuum in the interior of the housing (36) and/or by means of the holder (76). The spaces, which are open towards the top, between the fitting (18) and the supporting insulator (14), as well as between the fitting (28) and the switching chamber insulator (24) are filled with potting compound (38). Once this potting compound (38) has at least partially cured, the switch pole (10) is placed on the head by rotating the holder (76) about the horizontal axis (74), after which the spaces, which are now open towards the top, between the fitting (32) and the switching chamber insulator (24) as well as between the fitting (22) and the supporting insulator (14) are filled with potting compound (38). The enables simple assembly, automatic alignment of the contact pieces (48, 68) on top of one another and a sealing test, before the switch pole (10) is completely assembled. …<IMAGE>… |
