Three umbrella-type suspension insulator string applied to converter station

The utility model discloses a three umbrella-type suspension insulator string applied to a converter station, comprising insulator sheet sets and connection fittings, wherein each insulator sheet set is formed by a plurality of insulator sheets in series connection, and the insulator sheets are three umbrella-type suspension insulator sheets. One end of the insulator sheet set is connected to a converter station framework through the connection fittings, and the other end is in connection with leads through the connection fittings. The three umbrella-type suspension insulator string applied to a converter station has a large single sheet creep distance, and needs less insulator sheets under a same voltage class so as to substantially reduce the total length of the insulator string. Meanwhile when the three umbrella-type suspension insulator string is applied to the conflux bus in a converter station, the tension of the conflux bus can be substantially reduced and a framework can be optimized; and when the three umbrella-type suspension insulator string is applied to the Ac filter bus in the converter station, enough wiring space can be left for the downlead of an edge phase and three-phase downlead is tidy and beautiful.
