Dry-type air-core series reactor is an important equipment of compensation device of high voltage shunt capacitor

and is used to supress switching operation inrush current and reduce the harm of harmonics to shunt capacitor banks. The operating conditions require the reactor to operate stably

safely and reliably for a long time. However

high temperature will accelerate the insulation aging of the reactor proper and external protection

leading to the decrease in operation reliability

therefore

reasonable design shall be adopted to control the temperature rise. In this paper the structure of the product is mainly introduced

with the design and research on reducing the loss of the coil and busbar in particular. At the same time

the simulation means of the magnetic filed and temperature field are used to take effective measures to avoid the problems encountered by the type of reactor in the previous design and production. Moreover

the test verification is performed so to provide reference for the design and manufacture of large-capacity dry-type air core series reactor.
