Abstract

The invention relates to an optically-controlled water-cooling radiating thyristor valve box which is characterized in that the valve box is in a dual body vertical structure; a left valve unit and aright valve unit are connected in series to form a uniphase valve box; the left valve unit and the right valve unit are connected by a copper foil soft contactor; a water pipe unit of each valve unitis mounted in the middle of the valve unit, and a thyristors unit needing water cooling and a water-cooling resistance of a resistive-capacitive protective unit are mounted at two sides of the water pipe unit; other elements of the resistive-capacitive protective unit without needing of water cooling except the water-cooling resistance, a cabling channel unit, an equalizing ring unit are mounted at the periphery of the valve box. The water-cooling resistance and a damping capacitance are mounted on a resistive-capacitive bracket side by side in a concentrated layout manner. The resistive-capacitive protective unit uses modular design, and can assemble two eudipleural resistive-capacitive protective units by arranging the same water-cooling resistance and the damping capacitance on the resistive-capacitive bracket. The invention has the advantages of high reliability, small occupied area, separately arrangement of circuit and waterway and pure water cooling.

Description

technical field [0001] The invention relates to a water-cooled and heat-dissipating light-controlled thyristor valve group. The valve group is used in electric power, metallurgy and all other fields using light-controlled thyristors as core devices, and can be used for light-controlled thyristor valve groups with voltage levels of 66kV and above. Background technique [0002] Thyristors are currently the most widely used valve components. By controlling the firing angle of thyristors, the impedance can be continuously adjusted, which can enhance the power transmission capacity of the system, improve system stability, damp power oscillations, and suppress subsynchronous oscillations. The thyristor valve body usually has to withstand high voltage and high current, which needs to be realized by series and parallel connection of multiple thyristors. The thyristor valve group is the core component of the dynamic reactive power compensation device in the power system. [0003] Th...
