Abstract

The invention discloses a radiator cooling water path for a converter valve cooling system, which comprises a radiator pipeline, and further comprises a confluence metal water inlet pipe, a confluencemetal water outlet pipe and a radiator pipeline metal joint, and is characterized in that one end of the radiator pipeline is communicated with the confluence metal water inlet pipe through the radiator pipeline metal joint, and the other end of the radiator pipeline is communicated with the confluence metal water outlet pipe through the radiator pipeline metal joint; and the radiator pipeline metal joint is used for balancing the voltage at the two ends of the radiator pipeline. According to the invention, corrosion to the radiator can be avoided, and a voltage-sharing electrode does not need to be replaced.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to a radiator cooling water circuit used in a converter valve cooling system. Background technique [0002] HVDC transmission system has been widely used all over the world due to its advantages of long-distance large-capacity transmission and grid interconnection. In the HVDC power transmission system, the cooling system of the converter valve is used to dissipate heat for the thyristor to maintain its normal operating temperature. It can be said to be the most important auxiliary system in the whole system. Its cooling capacity is the key to ensure the safe and stable operation of the converter valve. factor. [0003] The existing published patent is a Chinese invention patent with the name of "a cooling waterway for a converter valve" and the publication number CN108495529A. This patent includes a cooling waterway for a converter valve module. The pipeline and cooling elements ...
