本考案は巻線の巻回間に電位制御導体を設けた
変圧器巻線に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transformer winding in which a potential control conductor is provided between turns of the winding.

巻線に対して直列の静電容量を形成する。 Generally, transformer windings using disk coils have a large series capacitance in the windings in order to equalize the potential distribution in the windings against steep wave front voltages such as lightning surges that enter from the line end or neutral point. A disc winding system with vibration damping and hems is adopted. This winding method uses an insulated rectangular copper strip as a coil conductor, and winds it into a disk shape. Multiple sections are stacked and connected in series via oil pipes, and a predetermined interval between turns of the winding wire is used. A potential control conductor is wound around the conductor. One end of the potential control conductor is connected to the coil conductor of an adjacent section and the other end is disconnected to form a capacitance in series with the winding.

るので巻線の占積率が悪くなり不経済であつた。 In such a wire-wound type transformer winding, a voltage two to three times the inter-section voltage of the normal winding is applied between the potential control conductor and the adjacent coil conductor. Therefore, when manufacturing the winding wire, there are methods to insulate the coil conductor that is in contact with the potential control conductor by making it thicker than the insulation of the coil conductor in the general winding part, or to increase the overall number of turns while keeping the insulation of the coil conductor thick. There is a way to wind it, but
In the former case, the insulation of the coil conductor is made thicker or thinner from the middle of the winding, resulting in poor workability. Furthermore, since the insulation dimensions of the potential control conductor and the coil conductor are different, a protrusion is formed in the oil passage between the sections, resulting in poor electric field distribution and an unavoidable drop in withstand voltage. In addition, in the latter case, the coil conductor is insulated more than necessary, which deteriorates the space factor of the winding and is uneconomical.

２のそれと同じ寸法にしたものである。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 11 denotes a disk winding with vibration damping and shielding.This winding 11 has sections 13a, 13b, and 13c, which are formed by winding a coil conductor 12 made of an insulated rectangular copper body into a disk shape. 14 and are stacked and connected in series. Between predetermined windings of each section, a potential control conductor 15 made of an insulated rectangular copper strip is wound together with the coil conductor 12, and one end of the conductor 15 is connected to the coil conductor of the adjacent section (not shown). The other end is disconnected. The insulation thickness t of the coil conductor 12 is the same as the insulation thickness of the general winding portion, and all the winding portions are uniformly covered. The dimensions of the copper body of the potential control conductor 15 are made smaller than those of the coil conductor 12, and the insulation thickness t' of the insulation applied thereon is made thicker than the insulation thickness t of the coil conductor 12, so that the voltage applied between it and the adjacent coil conductor is In addition, the insulation height h of the potential control conductor 15 should be set to the height h of the coil conductor 1.
It has the same dimensions as 2.

である。 With this configuration, there will be no protrusions on the surface of the winding in the oil passage, and the electric field distribution will be improved. Moreover, since the insulation thickness of the potential control conductor is increased, withstand voltage is ensured. Further, since the insulation thickness of the coil conductor is uniformly thin and only the insulation thickness of the potential control conductor is thick, the space factor of the winding wire is improved and the winding work is easy.
