ABSTRACT:
A converter valve which is constructed from modular elements is disclosed. Each of these modular elements comprises a group of thyristors arranged in side-by-side relationship and the drive means and circuit component group associated with such thyristor group. A metallic shield surrounds the thyristor group and its associated drive means and a portion of its associated component group. The shield, in turn, is supported within a metallic pressure tube which has both its ends closed off by bulkheads and is adapted to receive SF.sub.6 gas. The aforesaid bulkheads may be separate connecting members which, in addition, may also be designed as nodal elements and mechanical support points. The converter valve is constructed from a small number of the aforesaid modular elements, each element being replaceable without removing the gas from the entire valve.
