Abstract
In order to achieve improved mechanical properties for a coil (1), it is proposed to structure a first electroconductive winding (3) of the coil (1) as a coil former. This coil has a first connecting element (15), to which a second connecting element (17) is attached via an insulating part (25). The two connecting elements (15, 17) form the connections for the coil (1). In this way, a self-supporting coil structure is achieved. The coil (1) is particularly intended as an undervoltage winding with a low number of windings for cast resin transformers.
Claims20
A coil, particularly for a high-tension transformer comprising:
- a first electroconductive winding;
- a first connecting element;
- a second connecting element;
- an insulating member attaching said first connecting element to said second connecting element;
- and
- a second electroconductive winding arranged in insulated manner relative to the first winding and electrically connected to said second connecting element,
- wherein:
- said first winding forms a cylindrical former having an axial slit,
- an insulating part is inserted into said axial slit, and
- said second winding is carried by the first winding in an insulated manner.
An insulating part of a coil of a high-tension transformer that has a first winding forming a coil former and at least one outside winding, said coil former having an axial slit, wherein said insulating part comprises:
- a central portion disposable in said slit and mechanically joining two adjacent points of the first winding at said slit in an electrically insulated manner, and
- an outer surface facing the at least one outside winding and being substantially flush with an outer surface of the first winding.
