Insulated bus bar assembly in a voltage source converter
First Claim
1. An insulated bus bar assembly in a voltage source converter system comprising conductor bars (4,5,6) closely spaced for minimizing the generation of induced voltage in the assembly, wherein an elongate central conductor bar (5) is sandwiched between two side conductor bars (4;
- 6) in a plane parallel assembly, each gap that is formed between adjacent conductor bars being completely filled by a polymer insulator (8,9) that is braced in longitudinal contact with a planar side of the central conductor bar and an opposing, planar side of the adjacent side conductor bar, respectively, said polymer insulator being formed for providing freedom of access to exposed external sides of the bus bar assembly.

Abstract
The invention relates to a voltage source converter system, comprising a plane parallel bus bar assembly having conductor bars (4, 5, 6) closely related for reducing induced voltage in the assembly. Each gap that is formed between adjacent conductor bars is completely filled by a polymer insulator (8, 9) which is formed for providing complete freedom of access to fully exposed external sides of said bus bar assembly. The invention also relates to a molded, single piece polymer insulator comprising an elongate rib member (10) of continuous height and thickness, and elongate wing members (11, 12) angularly extended from each longitudinal periphery of the rib member.
