Reactor of low noise

The utility model relates to an electric system passive component technical field especially relates to a reactor of low noise. It includes first magnetic core post, second magnetic core post, last folder, lower folder, winding and three skeleton, combination department in every skeleton of first magnetic core post and second magnetic core post forms first air gap portion, there is the interval and forms interstice portion between first magnetic core post or second magnetic core post and the skeleton, first air gap portion sets up porous air gap board and first embedment material layer, porous air gap board through first embedment material layer respectively with first magnetic core post and second magnetic core support connnection, interstice portion sets up second embedment material layer, adopt the reactor of this structure, it can be under long -time operating mode environment, effectively restraines the noise of reactor. And, its simple structure, low in production cost is honest and clean. Its fine satisfy the low noise demand in, can satisfy current demand and large -scale production.
