| 摘要 |
An enclosed gas-insulated valve means for high voltage and high power, preferably for an installation for power transmission by means of high-voltage direct current, has an enclosure (1) of electrically conducting material and a semiconductor valve (SM1-SM10, RM1-RM11) arranged in the enclosure. The valve has electric main terminals (11, 12) arranged at opposite ends (LV, HV) of the semiconductor valve. One end of the valve (LV) lies at substantially the same potential as the enclosure (1), and the valve has a shape which tapers from this end towards the opposide end (HV). |
