Problems solved by technology

[0004] However, the equipotential electrodes used in the cooling system of the converter valve must be installed by drilling holes on the water pipe of the converter valve, which increases the number of joints and leakage points in the cooling system and reduces the reliability of the water pipe seal of the converter valve. and the structure of the equipotential electrode is complicated, and multiple sealing rings are set, which is troublesome to install and disassemble, which reduces the reliability of the equipotential electrode

Abstract

An embodiment of the invention discloses an equipotential electrode comprising a ring, at least two through holes arranged in the ring and used to connect a converter valve water pipe flange, and at least one equipotential pin. The outer diameter of the ring corresponds to the outer diameter of the converter valve water pipe flange connected with the ring, and the inner diameter of the ring corresponds to the inner diameter of the converter valve water pipe flange connected with the ring. One end of the equipotential pin is fixed to the inner diameter of the ring, and the other end of the equipotential pin extends to the inside of the ring along the radial direction of the ring. Another embodiment of the invention discloses an installation method of the equipotential electrode.

Description

technical field [0001] The invention relates to the field of direct current transmission, in particular to an equipotential electrode and an installation method. Background technique [0002] As my country's high-voltage direct current transmission technology becomes increasingly mature, the construction and use of direct current transmission systems are becoming more and more extensive. Among them, the converter valve cooling system is an important part of the DC transmission system, and its operation directly affects the transmission capacity of the entire system. [0003] At present, the cooling system of the converter valve mostly adopts the water-cooling method. Since the cooling water flows through the component radiator in the converter valve, it will carry a certain charge. If the breakdown of the water pipe causes water leakage, it is necessary to install an equipotential electrode on the water pipe. [0004] However, the equipotential electrodes used in the cooli...
