摘要： A grounded hollow cylindrical housing filled with SF.sub.6 encircles coaxially a rod-shaped electric conductor through a plurality of spaced, electrically insulating spacers. With the housing disposed horizontally, two spaced, hollow frustoconical dielectric members are connected to the inner surface of the housing adjacent to either surface of each spacer to overlap the latter. With the housing disposed vertically, a disc-shaped dielectric member fixedly extends through the conductor to be adjacent and overlap each spacer. Further, an annular dielectric member may be connected to the inner surface of the housing between the disc-shaped dielectric member and the spacer. The dielectric member is preferably of a poly-tetrafluoroethylene.

摘要： A high-voltage thristor converter and control therefor includes a plurality of thyristor modules and a transducer for feeding a control signal to each of the thyristor modules in response to an external operation command. The transducer produces an electrical control signal which is directed to a laser beam irradiator which converts the control signal into a laser beam signal. The laser beam signal is directed to a light sensitive element in the thyristor module for converting the laser beam signal into an electric control signal to trigger a thyristor element in the module.
