metallgekapselte hochspannungsschaltanlage dreipolig encased with bus bars

摘要

In the cylindrical encapsulation housing (1) the three parallel bus-bar conductors (e.g. 2,3) extend along the edges of a triangular prism with fixed contact pieces (e.g. 17,18) of the three isolating switches (14-15) on the axis of the cylinder. About half of the cross-section of the housing is available for the other parts of the isolating switches including esp. the moving contact pieces (36). Each fixed contact piece is located in the middle of the longest side of the triangle.
