An air core reactor of the type having a plurality of coaxial coil windings connected electrically in parallel by structurally rigid spiders at opposite ends of the reactor. There are two electrically conductive spiders at least one end of the reactor. Selected ones of the coil windings are connected to one of the two spiders and further selected ones of the coil windings are connected to the other of the spiders at the one end. In the preferred form the windings connecterd offset from one another around the coaxially disposed coils. In a further preferred embodiment, there are two electrically conductive spiders at each of opposite ends of the coaxial coils. In a still further preferred form, at least some of the coil windings are wound at least two conductors high with the same number of turns and wherein the ends of said two conductors are circumferentially offset from one another by preferably 180.degree.. In the most preferred form all coil windings are wound at least two conductors high ("n" high where "n" is an even number). The two spiders at one end may be a single structural unit with two separate electrically conductive spiders mounted thereon and carried thereby, or they may be two separate rigid electrically conductive structures that are internested or stacked one on top of the other. The two spiders at each of the opposite ends and the coil windings connected in parallel with the connections offset circumferentially provides a coil arrangement which can be checked readily for faults which are even relatively minor in nature or the detection of such faults in an operating system can be used to initiate a shut down of the system or parts thereof before substantial damage takes place.
An air core reactor comprising a plurality of coaxial helical coil windings, an electrically conductive and structurally rigid first spider at one end of said coil windings and two electrically conductive second and third spiders electrically insulated from one another at the opposite end of said coil windings, said coil windings being connected at said one end to said first spider and at said opposite end to said second and third spiders, a selected number of said coil windings being connected only to said second spider and the remaining ones connected only to said third spider.
An air core reactor comprising a plurality of coaxial, concentric, coil packages radially spaced from one another providing air cooling passages therebetween extending lengthwise of the reactor, each said coil package comprising at least one winding layer of two or more conductors wound helically at the same time one on top of the other, said conductors being electrically insulated from one another, a first rigid spider at one end of said coil packages, a second and a third rigid spider at the opposite end of said coil packages, each of said spiders having electrically connected, electrically conducting arms radiating outwardly from the axis of the coil packages, means electrically insulating the electrically conducting arms of said second and third spiders from one another, means typing together said spiders at opposite ends of the coils providing a physically rigid air core reactor unit, said helical coil windings being connected at opposite ends to said spiders at opposite ends of said reactor unit with a selected number of said helical windings connected at said opposite end to only said second spider and the remaining at such end connected only to said third spider.
An air core reactor comprising two or more cylindrical coaxial concentric coil packages electrically connected in parallel and each having helical coil windings characterized in that at least one coil winding in at least one of said packages has at least one multiple of two interwoven helical windings, in that said two interwoven helical windings are of an equal number of turns but with their beginnings and endings of the windings offset circumferentially around the reactor from one another and further characterized in that two spiders, electrically insulated from one another, are located at each of opposite ends of the cylindrical coil packages, a first selected number of said helical windings being connected at respective opposite ends to one of said spiders at the opposite ends of the reactor and the remaining connected to the other spiders at said respective opposite ends.
An air core reactor comprising at least two coaxial concentric coil packages disposed in radial spaced relation, each said coil package comprising one or more layers of at least one multiple of two insulated conductors, said at least one multiple of two conductors being helically wound at the same time providing interwoven helical windings having the same number of turns but wherein one is rotationally offset from the other about the axis of the reactor and means connecting all of said helical windings to one terminal at one end of the reactor and first and second spider means connecting all of said helical windings to a second terminal at an opposite end of the reactor, means electrically insulating said first and second spider means from one another, means electrically connecting a selected number of said helical windings to said first spider means electrically connecting the remaining helical windings to said second spider means.
