Title: Flyback transformer
Inventor: SHINOOKA TAKUMI
IPC: H04N3/19
Filed: 1984-12-17
Abstract: PURPOSE:To manufacture a small-sized and highly reliable transformer by providing ribs to fix a film condenser and a breeder resistance in an insulating case, accomodating these electronic pats in a case cover and, on the other hand, providing irregularities in the gap between the high tension coil and the insulating case. CONSTITUTION:In an insulating case 6 which accomodates a high tension coil wound around a high tension bobine 1, a breeder resistance 3 and a flat film condenser 8 are held with mounting ribs 6a, 6b respectively. As the terminal part of the film condenser 8 is close to the live section, insulation is retained by providing a concave part 6c in the insulating case 6. As the part 6c is shaped by utilizing the level difference part of the high tension bobine 1, the part 6c introduces no factor to produce large-sized transformers. Since these parts are covered with a replaceable insulating cover 7, correspondence is enabled by replacing the insulating cover even in the case of a flyback transformer that accomodates a breeder resistance alone.

Abstract: PURPOSE:To prevent the breakage of a bracket by oscillating the whole device including the bracket in the direction crossing at a right angle to a line with the connecting part with the support arm of a tower body as the center when the rocking of the wire and the wind pressure act on the device. CONSTITUTION:When the load balance of a transmission line 6 is changed by a snow cover to rock the transmission line 6 in the line direction, the rocking acts on a suspended insulator 7 through a suspension clamp 28 to rotate the suspended insulator 7 in the line direction with a shaft 26 as the center, while a bracket 5 and a lightning protecting insulator 8 are maintained in the static state. Thus, such an unreasonable force as causing a torsion in the bracket 5 and the lightning protecting insulator 8 never act. In this case, as a discharge electrode 31 in the lower part of the suspended insulator 7 is rotated in a circular form with the shaft 26 as the center and also moved nearly corresponding to the circular surface of a discharge electrode 37 in the lower part of the lightning protecting insulator 8, the aerial discharge gap G is maintained nearly constant.
