With the adoption of the instrument, the reliability of safe running of the converter valve cooling system can be effectively improved, the emergency handling efficiency of the field technical person to the converter valve cooling system can be raised, and the abnormal stopping time of the device can be effectively reduced, and therefore, more economic benefit can be created, and a good market popularization and application prospect is brought.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a fault analysis and diagnosis device for a converter valve cooling system and an implementation method thereof. Background technique [0002] The converter is the main equipment in the converter station, and its function is to convert AC power into DC power, or realize inverse conversion. In a direct current transmission project, the cost of the converter accounts for nearly a quarter of the cost of the entire converter station. The converters generally used in HVDC power transmission projects are thyristor valves. During the power conversion process, the components on the thyristor valves will generate a large amount of power consumption and heat. If the heat is not transferred in time, it will directly damage the thyristor valve element. The function of the converter valve cooling system is to transfer the power consumption and heat generation of each component on th...
