The invention relates to the field of flexible direct-current transmission, in particular to a voltage sharing electrode for converter valves. The voltage sharing electrode for converter valves includes a base which is assembled in an electrode mounting hole of a cold water pipe of a converter valve in a sealing manner. The base is equipped with a probe part used for being inserted into the cold water pipe of the converter valve. The outer surface of the probe part and the joint of the probe part and the base are covered with a corrosion-resistant conductive layer. The outer end of the base part away from the probe part is provided with an outer conductive connecting part electrically connected with the probe part. As the outer surface of the probe part and the joint of the base and the probe part of the voltage sharing electrode for converter valves are covered with the corrosion-resistant conductive layer, electrochemical corrosion during contact with water is avoided, and therefore,it is ensured that the probe part is firmly connected to the base and is prevented from falling off.
