Abstract

Valve cooling system is the major auxiliary system in HV DC converter station and it plays an important role in the normal operation of the converter valve. Taking the widely used water cooling system as an example

combining with some DC system operation failures caused by valve-cooling system exception

it concludes some typical defect types. Meanwhile

the corresponding preventive measures are given as references to enhance the operation reliability of the valve cooling system.
