The utility model relates to a starting resistor for high-voltage flexible direct-current power transmission. The starting resistor comprises a resistor box, a post insulator, a sleeve and a connecting tubular bus, wherein the resistance boxes are arranged in a layered manner, each layer is provided with more than two resistance boxes, each resistance box is internally provided with one resistancemodule, and the resistance boxes between adjacent layers are connected and supported by the post insulators; the sleeve is arranged on the side wall of each resistance box, the interior of each sleeve is connected with the corresponding resistance module through a connecting piece, the exterior of each sleeve is connected with the corresponding connecting pipe bus or the corresponding inlet and outlet terminal, and a series structure is formed. The utility model has the advantages of good insulating property, large impact resistance energy, small occupied area and good overall voltage-sharingeffect. The utility model can be widely applied to the technical field of high-voltage flexible direct-current power transmission.
