Title: On-load tap changer
Inventor: MATSUI SHINICHI
IPC: H01F29/04
Filed: 1986-03-14
Abstract: PURPOSE:To prevent withstand voltage from being deteriorated due to metallic powder which is generated in quantity due to wear during tap change, by installing a metal net on the upper part of a bottom plate of a tap selector so that movable contacts and collector contacts are housed inside a fixed contact insulating cylinder. CONSTITUTION:Since wear occurs in parts betwen the movable contacts 3 and the fixed contact 4, ones between the movable contacts 3 and the collector contacts 8, and the respective sliding parts in mechanism of driving the movable contacts, because of the movable contacts 3 moving during tap change in LTC 2, metallic powder is generated, dropping downwards and passing through a metal net 6 to be piled on a bottom plate 5 of a tap selector. Voltage is always impressed across the movable contacts 3, the fixed contacts 4, and the collector contacts 8 to the bottom plate 5 of the tap selector, and therefore a shield effect of the metal net 6 prevents metallic powder from standing and insulation distance from decreasing. Besides, installation of an insulating cylinder 7, in which the movable contact 3 and collector contacts 8 are housed in addition to the mounting of the fixed contacts 4, prevents the metal powder from being diffused inside a gas insulation transformer, and therefore preventing withstand voltage from being reduced over the whole of the gas insulation transformer.

Filed: 1985-03-18
Abstract: PURPOSE:To achieve a higher reliability, by always setting a pair of optical fibers with end faces thereof facing each other to lose this facing state of the pair of optical fibers with the deformation of a shape memory alloy at a specified temperature. CONSTITUTION:End faces of first and second optical fibers 2a and 3a of a pair of optical fibers A always face each other as shown by the soild line to form an optical fiber communication circuit. For example, when the ambient temperature of the apparatus exceeds a specified value due to the outbreak of a fire or the like, a shape memory alloy 9a deforms to the condition as shown by the dotted line from that shown by the solid line. As a support bar 7a rises with the deformation thereof, the optical fiber 2a supported in contact with the other end thereof 7a is displaced from the state as shown by the solid line to that as shown by the dotted line to made the optical fiber communication circuit of the pair of optical fiber 1A non-conductive. Thus, light from a light receiving element 4a already received with a light receiving element 5a fails to be received thereby enabling the detection of the ambient temperature of the apparatus that has exceeded a specified value.

Title: Insulated coil
Inventor: YAMADA TOSHIMITSU
IPC: H02K15/12
Filed: 1987-03-12
Abstract: PURPOSE:To secure an impregnating path by the formation of winding wrinkles regardless of tension in winding and to impregnate a resin perfectly under the constant impregnating conditions all the time, by winding film-lined mica tapes or sheets, which is partially contracted. CONSTITUTION:Mica paper 8 is stuck to film 7, and film-lined mica tape is obtained. One edge part 9 of the mica tape is thermally shrunk, and the partially shrunk mica tape is obtained. The tape is wound around a conductor 6. After impregnating resin 1 is impregnated, the resin is heated and hardened. When the tape is wound around the conductor 6, a gap 4 due to winding wrinkles, which are determined by the amount of shrinkage of the one edge part 9, is formed regardless of tension at the time of winding, and an impregnating path is secured. Thus a part up to the surface of the conductor 6 is filled with the impregnating resin 1. An insulated coil after the impregnation is heated and hardened. Here, the winding wrinkles formed of wrinkles 10 are contracted and disappear since the film 7 has a thermal shrinkage property. Because of the shrinkage, outflows of the impregnating resin can be prevented.
