Embodiment Construction

[0028] In FIGS. 1-7, which show the entire contact arrangement according to the invention in the assembled state, not all symbols are indicated for the sake of clarity of the illustration.

[0029] 1-7, which show the entire contact arrangement, show an insulating rod 1 on which the contact arrangement according to the invention is to be fastened. exist Figures 8 to 14 The middle part shows the individual parts of the contact arrangement according to the invention.

[0030] The insulating rod 1 has an upper fixing hole 11 and a lower fixing hole 12 for each contact device to be fixed. A U-shaped contact 2 is mounted on the insulating rod 1 . It has a contact area 21; this is an area where the contacts can be made above and below by a moving contact not shown. Furthermore, the contact has a long side 22 and a short side 23, and in the long side 22 there is a connecting hole 24, to which the electrical connecting wires for the winding taps of the variable transformer, not sh...

Abstract

The invention relates to a contact assembly. In said assembly, a U-shaped electric contact is fixed by means of two contact holders that surround the top and bottom of the contact and optionally also upper and lower shielding covers, by means of two bolts that run through corresponding bores of both the inventive components and the insulating bar, to which the contact is to be fixed.

Description

technical field [0001] The invention relates to a contact device for a tap changer or a mains voltage converter, which has a fixed electrical contact fixed on an insulating rod. Background technique [0002] Tap changers or mains voltage converters are known devices for switching between different winding taps of a voltage-regulated variable transformer. They have fixed-position contacts, which are electrically connected to the individual winding taps of the adjustable transformer, and are usually arranged phase-wise on circular tracks superimposed one above the other. In each horizontal plane, the fixed contact can be connected by a moving contact, which is usually a contact bridge connected to the electrical load lead. Here, the fixed contacts are fastened to vertically standing insulating rods made of cardboard or glass-fibre-reinforced plastic or in the wall of an insulating cylinder. [0003] The fastening on the insulating rod has hitherto generally been carried out ...
