ABSTRACT:
An enclosed thyristor valve of the type dividable into first and second portions comprises a tank, a thyristor valve assembly including a plurality of thyristor elements encased in the tank, a plurality of light guides extending through the tank for transmitting light signals for firing the thyristor elements, cooling pipes extending through the tank for circulating a coolant to cool the thyristor assembly, and bushings mounted on the tank for connecting the thyristor valve assembly with a power line system. The first and second portions are connected at mating flange portions disposed to the first and second portions of the tank. The light guides and cooling pipes are provided for the first portion of the tank so that the light guides and the cooling pipes are not disconnected from the first portion when the inspection and the maintenance of the thyristor valve are required.
