Abstract
The present invention relates to a contact unit for changing over between winding taps on a control winding of a tapped transformer. Such a contact unit can be used particularly preferably for electrical switchgear in high-voltage engineering, such as selector switches or changeover switches. A common feature of both kinds of device in this case is that the changeover between the winding taps on the control winding of the tapped transformer is accomplished without load current. The general inventive concept is to include the contact element of the contact unit in a separate contact housing, so that the contact element and the contact housing form a separate assembly and so that the contact housing, including the contact element, can be fixed in a recess provided in the contact mounting by means of a retaining element.
