摘要： PURPOSE:To ensure continuous operations one by one by a large current lightening by opening the lid of a casing by the ignition of an electric igniter by an induced current, drooping a display cloth and changing over a changeover switch. CONSTITUTION:A continuous lightening display is provided with a induction coil 14 and a plurality of displays 2, 2a and 2b as opposed to the passage of a lightening surge current 12. When the lightening current flows in a support 11 and a magnetic field 13 is generated in surroundings, an induced current 15 is generated in the coil 14. This operates an electric igniter 3, a gas is produced and the lid 6 of a casing 5 and a display cloth 7 are discharged. At the same time, a changeover switch 4 is operated to connect the common terminal of the display 2 of a first stage and a normally-opened terminal to each other and the electric igniter 3a of the display 2a of a second stage are connected to each other, taking a stand-by condition. Receiving further lightening, an operation described above is sequentially repeated.

SOLUTION: A main body 6 is made of graphite, and formed with a through hole 2, and the inner wall surface thereof is finished to a smooth surface nearly close to the mirror finish. An iron melting pan 3 is placed on a step difference 7 on the way, and the iron thermit 4 is filled thereon, and furthermore, the igniting agent 5 is arranged. Two pieces of an upper and a lower metal angles 14, 15 are threadedly fastened to each other by a bolt 11 from under and nuts 13, 12 from over, and the upper part is covered with a bottom part of the through hole 2. When the igniting agent 5 is ignited, the melting pan 3 is melted by the high reaction heat of the thermit mixture 4, and the molten steel is fallen onto the bolt 11 and the nut 12, and a slug is positioned thereon. After cooling it, when the main body 6 is pulled up, the bolt 11 and the nut 12 are strongly fixed to each other by the solidified molten steel, and the slug can be eliminated by a hammer or the like, Metal members can be thereby easily, permanently and strongly fixed to each other.

摘要： PURPOSE:To enable easy coupling and separation and electric connection or disconnection between a display unit and a detector and also reliable maintenance of a coupled state thereof by providing a removable coupling means and a disconnectable electric connecting means between the detector and the display unit. CONSTITUTION:Between a detector 40 detecting an abnormal current and a display unit 54 conducting display on the basis of a signal of the detector, a guide plate 47, a fastening plate 50 and an engaging projection 57 constructing a removable coupling means and a plug 52 and a socket 58 constructing a disconnectable electric connecting means are provided. With the display unit 54 rotated, according to this constitution, the projection 57 is made to correspond to a recessed part for insertion and removal of the fastening plate 50 and made to escape from and inserted into the guide plate 47, so that the display unit 54 be separated from the detector 40 and coupled thereto, while they are disconnected and connected electrically by the socket 58 and the plug 52. In a coupled state, besides, there is no possibility of the display unit 54 being separated from the detector 40 and dropping in the course of employment, because of firm coupling obtained from the engagement of the projection 57 with the fastening plate 50.

摘要： PROBLEM TO BE SOLVED: To provide a faulty position detecting system for overhead transmission line that can be heated to a fixed temperature made as high as possible and has a simple constitution and a long detecting distance. SOLUTION: A heater 4 is actuated by the output of a fault detector 3. The heater 4 is constituted of a heating element 41 and a heat storing body 42 and the body 42 is arranged between the heating element 41 and an overhead ground wire 45 and, at the same time, a mixed solution prepared by mixing a plurality of kinds of solutions with each other so that the boiling point of the mixed solution so set at a high temp, set exceeding the heat-resisting temperature of an optical fiber 44, is contained in the heat storing body 42. A faulty position detecting device 5 only measures the intensity distribution of the anti- Stokes' light or Stokes' light of Raman scattering light and detects a faulty position from the variation of the intensity distribution near the place to which the heater 4 is installed.
