Abstract (en)
The invention relates to a reactor for application in a transport or distribution network for electrical energy and comprising at least one winding arranged in a metal housing, wherein means are arranged for applying an axial pressure force to the winding, wherein the metal housing forms part of the pressure means. This renders superfluous the use of extra constructions for applying an axial pressure force to the reactor. This avoids the problems associated with such constructions, while the possibility is likewise created of giving the reactor a smaller, lighter and less expensive form. According to a preferred embodiment a magnetic circuit is arranged inside the housing to screen the stray field generated by the winding, wherein at least a part of the magnetic circuit functions as means for transmitting from the housing the axial pressure force to be applied to the winding. <IMAGE>
