Abstract

In view of temperature field distribution of±800 kV/6 250 A high capacity dry-type smoothing reactor with rainproof and noise reduction device

the temperature field distribution characteristics of±800 kV/6 250 A drytype smoothing reactor by the use of combination of simulation method of coupling fluid-thermodynamic with test on the basis of UHV DC transmission project with transmission capacity at 10 GW is studied in this paper.It is shown by the test result that:Firstly

the result of temperature-rise test and that of simulation of smoothing reactor is in agreement and the rationality and accuracy of the simulation model are verified.Secondly

the rainproof and noise reduction device changed the flow direction of the air above the reactor

increased the air flow resistance and affected heat dissipation effect of the reactor.Thirdly

the actually measured hot spot temperature rise of the ±800 kV/6 250 A drytype smoothing reactor is 68.1 K（at 14th package）and meets design requirements.The study result mentioned above can provide reference for the study and optimization design on temperature field distribution of dry-type smoothing reactors.
