Abstract
The invention relates to a three-phase shunt reactor, which is provided with an iron core and coils wound thereon, wherein the iron core and the coils are mounted in an oil tank integrally. The iron core has a three-phase five-post structure including three mandrels, two side yokes, an upper yoke and a lower yoke, each mandrel consists of iron cakes, and the two side yokes and the lower yoke are clamped by clamping devices. The coil of each phase is a pancake coil with a continuous inner panel and goes out from the middle. The upper yoke, the lower yoke and the two side yokes have wide yoke structures, and shielding devices are arranged in magnetic flux leakage passages, and the width of each wide yoke structure covers the main passage. The two side yokes and the lower yokes are clamped by U-shaped clamps and double-row feed-through bolts from the thickness direction. The mandrels are clamped with the upper yoke and the lower yoke by multiple mandrel feed-through rods. The three-phase shunt reactor has the advantages that vibration is reduced, noise is lowered, additional loss of magnetic flux leakage to structural parts is decreased greatly, and electric field is more uniform in distribution.
